## Title
Monitoring medical procedures by estimated radiation exposure

## Abstract

Systems and methods monitoring progress of procedures by radiation exposure are provided. Position data is received for an equipment item used for the procedure and configured to produce radiation (“radiation device”). Position data is received from the tracking device during the procedure. An estimated exposure level is determined by a controller for the individual based, at least in part, on the position data from the tracking device relative to the position data from the radiation device and compared to a benchmark. If the estimated exposure level for the individual exceeds the benchmark, an electronic notification is generated.

TECHNICAL FIELD
Exemplary embodiments relate generally to systems and methods for monitoring medical procedures by estimated radiation exposure.
BACKGROUND AND SUMMARY OF THE INVENTION
Many modern surgical procedures require the use of equipment which produces radiation. For example, to reduce the invasiveness of surgery, small devices are often used in conjunction with imaging equipment. A more specific example is vascular surgery, where small devices are inserted into a patient's vascular system and imaging equipment is used to track device position and blood flow. As radiation is released from such machines, it encounters the patient and other objects, such as the operating table, and may scatter through some or all of the operating room. Being invisible to the human eye, radiation exposure zones are difficult to track. Repeated or extended exposure to even minimal amounts of radiation can result in health risks to operating room staff. Radiation shielding and protective equipment, while helpful, do not altogether eliminate such exposures.
It is known to provide radiation tracking devices to medical personnel in an operating room to assist with tracking radiation exposure. These radiation tracking devices may be checked periodically, such as once a month, to determine approximate exposure levels over potentially multiple events of exposure in a given month. As a general rule, medical personnel are encouraged to stay at least six feet away from radiation producing equipment, when possible, to minimize exposure. However, it is difficult for medical personnel to constantly and accurately determine their distance from the equipment, especially in the course of an operation on a patient. Furthermore, radiation intensity varies based on a number of factors which change the radiation intensity for a given location. Medical personnel are able to make changes to their body positioning to reduce exposure if made aware of the location of the invisible and potentially harmful radiation. Therefore, what is needed is a system and method for visualizing scattered radiation in a medical facility.
Systems and methods for visualization of scattered radiation in a medical facility are disclosed. The medical facility may comprise an operating room, for example, though the systems and methods may be used with other medical facilities such as but not limited to, training environments, simulators, laboratories (e.g., catheterization labs), radiology suites, imagining scanner rooms (e.g., CT scanners, MRI scanners), combinations thereof, or the like. The medical facility may comprise one or more items of medical equipment configured to produce radiation for medical reasons such as, but not limited to, treatment and/or diagnosis of diseases. Examples of such equipment which produces radiation includes, but is not necessarily limited to, imaging equipment (e.g., CT scanners, MRI machines, X-RAY machines, electron microscopes, fluoroscopy equipment, combinations thereof, or the like), radiation therapy machines (e.g., external beam radiation machines, sealed source radiation therapy machines, unsealed source radiotherapy machines, photon therapy machines, oncology equipment, combinations thereof, or the like), accelerators, or other equipment capable of producing radiation for medical treatment purposes, that in high enough levels of repeated exposure could be harmful to humans.
Alternatively, or additionally, the medical facility may comprise radioactive medical products and/or medical products which naturally produce radiation, or are configured to produce radiation for medical reasons, such as but not limited to, the treatment and diagnosis of diseases. Examples of such products include, but are not limited to, various isotypes, radiopaque markers, fluoroscopy fluids, seeds, combinations thereof, or the like.
These items of equipment and/or products may be configured to deliberately produce what is considered to be safe or otherwise medically acceptable levels of exposure to radiation for patients, for their medical care. Examples of such radiation include, but are not necessarily limited to, gamma rays, x-rays, charged particles, combinations thereof, or the like. While generally safe or otherwise medically acceptable levels of radiation exposure to patients having a given medical procedure is one thing, repeated levels of radiation exposure to medical personnel who conduct multiple medical procedures over multiple patients, is another. For example, medical science generally accepts a safe or medically acceptable level of radiation exposure for patients, but exposure to that same level and amount of radiation by a medical professional over a long career may be of more concern.
Information may be provided regarding, for example without limitation, a type of radiation producing medical equipment device, patient height, and patient weight. The position of one or more items of equipment in the medical facility may be determined from one or more position sensors. The equipment may include radiation producing equipment. Alternatively, or additionally, the equipment may include medical equipment which scatters radiation, deliberately or unintentionally, when placed in the path of the same. Examples of such equipment which scatters radiation include an operating table, trays, cabinetry, medical devices, combinations thereof, or the like. The operating table is a common source of radiation scatter as it is often placed directly in the path of a radiation beam and comprises one or more metals which scatter encountered radiation.
A visualization of the radiation scatter may be generated by a controller and provided at one or more visualization devices. The visualization devices may include augmented reality (“AR”) tracking devices, electronic displays, and/or projection devices.
The visualization may be configured to appear fixed relative to the various visualization devices such that as medical personnel move about the medical facility and/or change their gaze, the visualization is updated at their visualization device to appear to be in the same location. The location may comprise, for example without limitation, adjacent to or at radiation producing equipment, equipment which scatters radiation, the patient, the operating table, combinations thereof, or the like. As the position of the operating table, the patient, equipment which produces radiation, equipment which scatters radiation, and/or other equipment and/or medical personnel in the medical facility is changed, the visualization may be updated.
Each medical personnel in the medical facility may be outfitted with a position tracking device. Alternatively, or additionally, various pieces of equipment in the medical facility, such as but not limited to, the operating table, radiation producing equipment, storage equipment, trays, radiation producing products, medical devices, equipment which scatters radiation, and the like may be outfitted with position tracking devices. In this way, the position of such people and/or items may be tracked for updating the visualization. Multiple position devices may be utilized for a given person or piece of equipment. Updates to the visualization may be made in substantially real time.
The visualization may comprise a multi-layered cloud or sphere, though other forms such as, but not limited to, lines, shapes, text, color, or the like may be utilized in the alternative or in addition. Various areas of the visualization may be color coded, shape coded, marked with text, provided in certain densities or intensities, some combination thereof, or the like to indicate the danger level associated with expected radiation intensity for that area. In another exemplary embodiment, a single light may be increased in intensity or illuminance to indicate relatively higher relative radiation. Alternatively, or additionally, sounds may be emitted in varying tone, frequencies, amplitudes, some combination thereof, or the like as the personnel approach radiation producing equipment. Regardless, the visualization and/or audio feedback may provide medical personnel in the medical facility with real time, qualitative type feedback regarding their expected level of danger. Medical personnel may use this feedback to limit their exposure level.
The visualization may be provided at a transparency level sufficient to permit the personnel to see the patient and equipment in the room while also viewing the visualization. By way of non-limiting example, transparency levels of 20% or under may be utilized.
In exemplary embodiments, at least some of the visualization devices may comprise radiation exposure tracking devices. Exposure data from such devices may be used to improve the accuracy of the visualization and/or track personnel exposure levels. Alternatively, or additionally, relative exposure may be tracked by position of the personnel while the radiation producing equipment is active. Regardless, exposures data may be recorded to calculate various exposure levels over time, predicted exposure levels, average exposure levels, some combination thereof or the like. Such data may be generated into one or more reports and/or provided as alerts, such as when a person approaches a periodic goal or threshold.
In other exemplary embodiments, the medical facility may comprise one or more training facilities and/or simulators. In such cases, some or all of the medical equipment in the medical facility, such as but not limited to the radiation producing equipment, radioactive products, equipment which scatters radiation, and/or other medical equipment may be simulated or real. The radiation emitted by such equipment and/or products and/or scattered by other such equipment may be simulated and the visualization may be provided to simulate such radiation. This may be used to raise awareness of radiation exposure, train personnel, evaluate the impact of procedures on radiation exposure, test new procedures, combinations thereof, or the like.
It will be appreciated by those of skill in the art that the systems and/or methods shown and/or described herein may be used in conjunction with any type of healthcare setting, with any type of equipment and/or to visualize any type of radiation. The types of radiation may be those defined by the Occupational Safety and Health Administration, Nuclear Regulatory Commission, Centers for Disease Control, the Food and Drug Administration, or other governmental or regulatory body, standards setting organization, combinations thereof, or the like, that in high enough levels and/or amounts of exposure is deemed to be harmful to humans. For example, without limitation, such radiation may include the types or kinds of radiation that in high enough levels of exposure is known to increase the incidence of cancer in humans following such exposure.
Judging complexity and progress of a medical procedure (hereinafter also a “case”) is a difficult and uncertain endeavor. This is particularly unfortunate considering that case complexity and progress are important measures of patient outcome as well as operator and other personnel performance. Therefore, what is needed are systems and methods for monitoring case complexity and progress.
System and methods for monitoring progress and complexity of a medical procedure, such as by tracking estimated radiation exposure are provided. Radiation exposure may serve as an effective surrogate for case progress and complexity. More complex cases tend to require additional imaging, operating time, and/or physical proximity to radiation producing and/or scattering equipment (which is typically physically proximate to the patient) for the operator or other personnel relative to less complex cases. Thus, more complex cases, or even portions of cases, may tend to result in increased radiation exposure relative to other, less complex cases, or portions of cases. Alternatively, or additionally, as a case progresses, radiation exposure may increase. For example, without limitation, multiple imagining sessions may be performed during the course of a procedure and/or the operator or other personnel may spend more time physically proximate to radiation producing or scattering devices as a case proceeds. Thus, radiation exposure may increase as a case is performed.
Radiation exposure levels during a case may be estimated using the tracking devices, with or without the scattered radiation visualization. Where tracking devices worn by various personnel for a procedure report a location within a radiation scatter area while radiation production is underway, the controller may record an estimated radiation exposure amount for the individual(s). Alternatively, or additionally, the radiation exposure measurement devices may be utilized.
Estimated radiation exposure may be tracked, such as by multiple individuals over multiple procedures at multiple medical facilities, to develop a database of estimated radiation exposure for various medical procedures. Such radiation exposure may be associated with personnel information regarding the individual wearing or otherwise associated with the tracking device and/or with patient information. For example, information about personnel may include demographic information, education, training, and/or certification information, associated medical facilities, combinations thereof, and the like. Such estimated radiation exposures may, alternatively or additionally, be associated with information about the procedure performed, such as but not limited to, medical codes, date and time information, devices used, combinations thereof, or the like. This information may be analyzed to develop averages, medians, ranges or other benchmarks. The benchmarks may be specific to the type or kind of procedure performed (e.g., by CPT or IDC code), the personnel or certain personnel information (e.g., experience, training, education, etc.), a medical facility or geographic area, patient demographics (e.g., age, co-morbidities, risk factors, etc.), combinations thereof, or the like.
After further cases are performed, or while such further cases are underway, radiation exposure levels (estimated and/or actual) may be tracked and compared to such benchmarks to identify the need for intervention. For example, where a tracked radiation exposure level is found to exceed a benchmark by more than a predetermined amount, an intervention may be triggered. Such benchmarks may be developed automatically, on demand, combinations thereof, or the like. Machine learning, artificial intelligence, and/or statistical analysis techniques (e.g., averages, weighted averages, median, mode, standard deviations, etc.) may be utilized to develop such benchmarks.
Interventions may include, for example without limitation, identifying candidates for additional training and/or education, providing such training and/or education, providing access to medical literature and/or training materials, videoconferencing or teleconferencing access to other medical personnel (e.g., a more experienced operator) or other relevant parties (e.g., technical support staff), access to a chatbot or artificial intelligence entity, auditory or visual feedback, notifications information, information regarding new devices or techniques available to improve efficiency and/or reduce exposure, combinations thereof, or the like. Such interventions may be provided in substantially real-time, such as during the procedure, or after, such as but not limited to, in a post-operative review, during quarterly, annual, etc. review, combinations thereof or the like. Particularly where the interventions are provided while a procedure is underway, such interventions may be provided by way of the AR tracking devices in an augmented reality fashion. Interventions may be provided directly to the personnel or to other associated parties such as hospital or other medical practice administrators, medical device companies, insurance providers, combinations thereof, or the like, to name a few examples without limitation.
While some discussion is made herein with regards to medical applications, those of skill in the art will recognize that applications in other radiation environments may be realized. For example, without limitation, such radiation producing environments may include security screening areas which utilize radiation producing equipment, nuclear power facilities, nuclear production facilities, combinations thereof, or the like.

The AR tracking device 46 may comprise the network connectivity device 38. The location and/or radiation exposure may be monitored and/or transmitted continuously or periodically to remote devices, such as but not limited to, the controller 56.
FIG. 7 through FIG. 10 illustrates exemplary medical facility 52 with exemplary augmented reality system 48. The medical facility 52 may comprise an operating room, for example, though the augmented reality system 48 may be utilized in association with other types of medical facilities 52 may be utilized such as but not limited to, training environments, simulators, laboratories (e.g., catheterization labs), radiology suites, imagining scanner rooms (e.g., CT scanners, MRI scanners), combinations thereof, or the like.
The medical facility 52 may comprise one or more items of medical equipment 100 configured to produce radiation for medical purposes, such as but not limited to, the treatment and/or diagnosis of disease. Such radiation producing medical equipment 100 may comprise, for example without limitation, imagining equipment (e.g., CT scanners, MRI machines, X-RAY machines, electron microscopes, fluoroscopy equipment, combinations thereof, or the like), radiation machines (e.g., external beam radiation machines, sealed source radiation therapy machines, unsealed source radiotherapy machines, photon therapy machines, oncology equipment, combinations thereof, or the like), accelerators, or other equipment capable of producing radiation for medical care purposes, such as but not limited to, gamma rays, x-rays, charged particles, combinations thereof, or the like. Alternatively, or additionally, the medical facility 52 may comprise one or more radioactive medical products and/or products capable of producing radiation for medical purposes, such as but not limited to, the treatment and/or diagnosis of disease. Such products may include, for example without limitation, various isotypes, radiopaque markers, fluoroscopy fluids, seeds, combinations thereof, or the like which produce radiation.
The medical facility 52 may comprise, alternatively or additionally, medical equipment which scatters radiation 54, deliberately or unintentionally, when placed in the path of such radiation. Examples of such equipment which scatters radiation 54 includes, but is not limited to, operating tables, trays, cabinetry, medical devices, metallic surfaces, shielding, combinations thereof, or the like. The operating table is a common source of radiation scatter as it is often placed directly in the path of a radiation beam and comprises one or more dense metals which may scatter encountered radiation.
Medical personnel in the medical facility 52 may be outfitted with the AR tracking device 46. The AR tracking device 46 may be configured to display a radiation scatter visualization 50 at the display portions 44 of the AR tracking devices 46 worn by each person. FIGS. 7 through 10 illustrate exemplary embodiments of the visualization 50 as it may appear to an individual wearing the AR tracking device 46. However, the visualization 50 may be displayed in the context of the user's position and/or gaze. Stated another way, FIGS. 7 through 10 illustrate what a user observes when wearing the AR tracking device 46 from a perspective view of the medical facility 52. The user may see the surgeon in the middle of the visualization 50 and others off to the sides of the visualization 50. The surgeon in the middle may see the visualization 50 all about them while looking at a patient on the operating table and/or seeing other equipment, such as but not limited to the equipment which scatters radiation 54, in the medical facility 52.
The visualization 50 may be generated and updated, at least in part, by a controller 56. The controller 56 may be configured to utilize one or more reference or registration points to virtually affix the visualization 50 relative to the personnel in the room such that the visualization 50 appears fixed as persons wearing the AR tracking devices 46 move about the room. The visualization 50, for example without limitation, may be virtually affixed relative to the radiation producing equipment 100, the radiation scattering equipment 54, other equipment, other part of the medical facility 52, the patient, some combination thereof, or the like.
In exemplary embodiments, without limitation, the controller 56 may be configured to process data stored in memory of a two or three-dimensional radiation intensity diagram 10,20, underlying data regarding the same, or the like, for the particular equipment 100 being used in the room, along with other inputted or detected data such as the patient's body data, radiation scattering equipment 54 position data, equipment 100 position data, and/or type of other equipment, facility parameters, etc., as further explained below. The controller 56 may be located in the medical facility 52 or remote therefrom. The controller 56 may be in wired and/or wireless electronic communication with each AR tracking device 46, device 30, and/or tracking device 36 in the medical facility 52. The visualization 50 may be updated at the various AR tracking devices 46 by the controller 56 periodically or continuously. The visualization 50 may be updated in substantially real time, such as but not limited to, as data is received and processed accounting for normal delays due to transmission time, processing time, and the like.
The visualization 50 may comprise one or more shapes, text, lines, some combination thereof, or the like of the same or various types to represent the intensity of the radiation. In exemplary embodiments, the visualization 50 may comprise a multi-layered cloud or sphere, though any form of the visualization may be utilized. For example, without limitation, the visualization 50 may comprise a first color representing a high level of relative radiation intensity, a second color representing a medium level of relative radiation intensity, and a third color representing a low level of relative radiation intensity. The first color, for example without limitation, may comprise a shade of red, the second color a shade of orange, and the third color a shade of yellow. As another example, without limitation the first color may comprise a shade of red, the second color a shade of yellow, and the third color a shade of green. Any color, or combination of colors may be utilized.
As another example, the visualization 50 may comprise a multi-layered cloud or sphere where certain shapes are displayed at a first density to represent a low level of relative radiation intensity, a second density to represent a medium level of relative radiation intensity, and a third density to represent a high level of relative radiation intensity.
Any number of layers, colors, shapes, lines, text, some combination thereof, or the like may be utilized. Each change in layer, color, shape, line, text, some combination thereof, or the like may correspond with a change in level of relative radiation intensity. The visualization 50 may be displayed at a transparency sufficient to provide visibility of the patient and/or equipment through the visualization 50 yet of adequate opaqueness to call the visualization 50 to the user's attention. An exemplary transparency is at or below 20%, though any percentage may be utilized.
The various layers of the visualization 50 may be visible simultaneously such that the user can see each layer of the visualization 50. Alternatively, each layer of the visualization 50 may be visible only as the user approaches and/or enters the layer of the visualization 50.
As yet another example, without limitation, the visualization 50 may comprise one or more lights of monochromatic or multiple colors which becomes brighter or otherwise more intense as a user approaches the machine 100 or other area of higher relative radiation intensity. The one or more lights may be of monochromatic or multiple colors which becomes dimmer or otherwise less intense as a user steps away from the machine 100 or moves into areas of lower relative radiation intensity.
Alternatively, or additionally, one or more speakers 59 may be provided. The speakers 59 may be in electronic communication with the controller 56. The controller 56 may be configured to cause the speakers 59 to emit an audible tone(s) or message(s) regarding relative radiation intensity. For example, without limitation, the tones emitted may increase or otherwise differ in tone, frequency, pitch, amplitude, some combination thereof, or the like as the user approaches areas of relatively higher radiation intensity and decrease as the user approaches areas of relatively lower radiation intensity. Audible messages regarding the relative radiation intensity, or the like may be emitted.
Each AR tracking device 46 may be configured to provide a visualization 50 of the scattered radiation specific to the location and/or direction of gaze of the person wearing the AR tracking device 46. Personnel may move about the medical facility 52 and/or redirect their gaze and be provided with a substantially real-time update of the visualization 50 while still able to view the patient, the radiation producing equipment 100, the radiation scattering equipment 54, other equipment, and otherwise perform their duties. In this way, personnel may be appraised of at least the approximate level of relative radiation intensity in a given area in the room. Personnel may use the visualization 50 as a guide for adjusting their position within the medical facility 52, where possible, to minimize their exposure. For example, without limitation, a surgeon may lean backwards when activating the equipment 100 to minimize exposure. As another example, without limitation, an anesthesiologist who may not need to be physically close to the patient to perform his or her duties may position themselves outside of the visualization 50 to minimize his or her exposure. As yet another example, without limitation, a nurse may pull his or her hands away from the patient when the equipment 100 is active to move their hands from a relatively high to a relatively low area of relative radiation intensity.
The controller 56 may be configured to accept user input such as, but not limited to, at a touch screen interface, mouse, keyboard, voice recognition interface, some combination thereof, or the like. User input may include specification information for the machine 100, height of the patient, weight of the patient, radiation scatter, radiation intensity, radiation type, machine 100 settings, user preferences, some combination thereof, or the like.

In exemplary embodiments, each controller 56 may comprise one or more timekeeping devices 412 configured to track date and/or time information in conjunction with received data, such as the radiation exposure data. In other exemplary embodiments, such timekeeping may be achieved at the individual components of the augmented reality system 48, the projection system 60, the electronic display system 70, and/or the combined system 80, such as but not limited to, the tracking device 36, the AR tracking device 46, the position tracking device 57, combinations thereof, or the like, or otherwise provided, and provided to the controllers 56. Such components may comprise timekeeping device 412 and the time and/or date information may be reported to the controllers 56 for recordation at the database(s) 402.
The database(s) 402 may be integrated with the controllers 56 or remote therefrom. Communication between the controllers 56 and the database 402 may be accomplished by way of network communication devices 404 at each respective device and one or more networks 406.
An analytics subsystem 408 may be configured to process some or all of the data stored at the database 402. The analytics subsystem 408 may be integrated with the controllers 56 and/or database 402, or may be remote therefrom and in electronic communication with the same by way of said network communication devices 404 and networks 406. The analytics subsystem 408 may comprise one or more executable software routines configured to analyze the stored estimated radiation exposure data and other information to generate various benchmarks, reports, and/or measures, which may be used to trigger interventions as further discussed herein.

The type, kind, or number of interventions provided may be specific to the procedure performed, the recipient of the intervention, the benchmarks met or exceeded, user preference, personnel information, medical facility information, procedure status (e.g., underway or post-operative), combinations thereof, or the like.
The controllers 56, database 402, and analytics subsystem 408 may comprise any type or kind of electronic device such as, but not limited to, computers, electronic storage devices, processors, servers, combinations thereof, or the like. Such electronic devices may be the same or different across the controller 56, database 402, and/or analytics subsystem 408.
The analytics subsystem 408 may comprise a predictive module 422. The predictive module 422 may be configured to generate predicted exposure levels for the personnel. The predictive module 422 may be configured to utilize extrapolation, artificial intelligence, and/or machine learning techniques or algorithms to determine predicted exposure levels for personnel over a period of time (e.g., day, week, year, career, etc.). For example, without limitation, an operator's predicted exposure for a period of time may be generated based on a number and type of prior procedures performed, operator certification, training, experience level, combinations thereof, or the like. The database 402 may be queried to retrieve data relevant to such specifics and an average or other measure of exposure per procedure may be generated. The operator's predicted number of procedures, of the same or different type, for the time period may be developed based on the operator's history or averages for similarly situated operators, and the average or other value may be multiplied by the predicted number of procedures to develop a predicted exposure value. The predicted value may be added to any current cumulative values to predict a cumulated exposure level for a future time period. The prediction may also be based on scheduled cases. The same or similar techniques may be utilized for other personnel including nurses, assistants, anesthesiologists, combinations thereof, or the like. These examples are provided to be illustrative and are made without limitation.
FIG. 18 illustrates an exemplary profile 414 which may be generated by the analytics subsystem 408. The profiles 414 may be generated on-demand or periodically. The analytics subsystem 408 may be configured to send data sufficient to generate the profile 414 at any number of remotely connected electronic devices, including but not limited to, the AR tracking devices 46, by way of the projection devices 62, at the electronic displays 72, at one or more remote electronic devices 424A, 424B (e.g., computer, server, tablet, smartphone, etc.), combinations thereof, or the like. Any number or type of remote electronic devices 424 may be utilized. For example, without limitation, the remote electronic devices 424 may be associated with hospital or medical practice administrators, personnel, insurance providers, medical device companies, combinations thereof, or the like.
The profile 414 may comprise any type of kind of data tracked by the system 400. For example, without limitation, the profile 414 may comprise a photo or other visual depiction of the individual with which the profile is associated (e.g., the operator or other personnel), name and other demographic information for the individual, practice area, certifications and/or completed trainings, associated hospital or other practice information, experience information, age, average or other measure of estimated radiation exposure per procedure, average or other measure of actual radiation exposure (e.g., as measured by the radiation exposure measurement devices 32), cumulative estimated and/or actual radiation exposure information for a given time period (e.g., year, month, quarter, etc.), procedure information (e.g., CPT, IDC, or other code, date and time information, exposure information, radiation producing equipment used, radiation scattering items used, medical devices used, procedure techniques used, patient information, etc.), average or other measure of number of procedures for a given time period (e.g., year, month, quarter, etc.), combinations thereof, or the like.
The profiles 414 may, alternatively or additionally, be developed for hospitals, medical practices, medical facilities, medical groups, geographic regions, procedures, combinations thereof, or the like. The profiles 414, or underlying data, may be utilized by personnel, hospital or practice administrators, peers, medical societies, medical device representative or companies, combinations thereof, or the like to target candidates for further training and/or education, management and workload balancing, marketing opportunity, development or commercialization opportunities, combinations thereof, or the like. The profiles 414 and related data may be depersonalized or otherwise deidentified in exemplary embodiments, though such is not required. To name a few examples, without limitation, hospitals may identify operators whose procedures typically result in higher exposure levels and target those candidates for further training or education. Medical device companies may identify procedures, or parts or procedures, having higher exposure levels and develop new devices or techniques for those procedures. Hospitals, medical device companies, or insurance companies may identify practices with higher exposure levels for particular procedures and suggest investment in newer equipment or training of new techniques.
A profile 414 may be generated for each personnel associated with one or more tracking devices 36 and/or AR tracking devices 46 or otherwise registered with the system 400. However, such profiles 414 may, alternatively or additionally, be generated for certain such personnel, such as on an on-demand basis for a subset of such personnel. For example, without limitation, a hospital administrator may generate a profile for all personnel associated with a particular practice group. As another example, a profile 414 may be generated for each personnel at approximately each anniversary of hiring as part of an annual review process.
The database 402 may form part of, or be in electronic communication with, an electronic health record (“EHR”) system. Alternatively, or additionally, the controllers 56 may be in electronic communication with said EHR system. In this way, radiation exposure (actual and/or estimated) and other procedure information for said patient and/or said personnel may be stored at said EHR system. One or more of the remote devices 424 may comprise one or more EHR systems, in exemplary embodiments.
FIG. 19 illustrates exemplary logic for use with the system 400. The radiation exposure data (actual and/or estimated) may be tracked, such as by way of the augmented reality system 48, the projection system 60, the electronic display system 70, and/or combined system 80, the tracking device 36, the AR tracking device 46, the position tracking device 57, combinations thereof, or the like. Such data may be tracked over multiple procedures associated with multiple personnel, patients, and/or medical facilities. This data may be used to build a data set within the database 402. The data may be analyzed by way of the analytics subsystem 408.
In exemplary embodiments, estimated and/or actual exposure levels may be cumulated for a given procedure for purposes of triggering interventions. The analytics subsystem 408 may determine radiation exposure for each instance radiation producing medical equipment 100 is activated, such as but not limited to, the position of each personnel as determined by the tracking device 36, the AR tracking device 46, the position tracking device 57 relative to the radiation scatter intensity field data 10 associated with the radiation producing medical equipment 100 activated. Such exposure may be compared against the benchmarks by the analytics subsystem 408 for each instance of exposure. Alternatively, or additionally, such exposure may be cumulated for a given procedure against the benchmarks by the analytics subsystem 408. Such individual or cumulative exposures against benchmarks may be used to trigger interventions from the intervention subsystem 410.
The analytics subsystem 408 may be configured to generate various benchmarks based on the data set at the database 402. For example, without limitation, the analytics subsystem 408 may generate average radiation exposure data for various procedures, such as but not limited to, as classified by CPT code, IDC code, or other classification, technique(s) used, equipment used, combinations thereof, or the like. As another example, the average radiation exposure data may be analyzed by hospital, practice, operator information (e.g., age, experience, training, associated hospital or practice, etc.), medical staff information, geographic region, patient information (e.g., demographics, presenting symptoms, outcome, etc.), experience, training, certification, procedures using similar equipment or techniques, equipment used (e.g., radiation producing equipment, radiation scattering equipment, medical devices utilized) combinations thereof, or the like. Essentially, radiation exposure may be measured as a surrogate for case complexity and/or progress. In exemplary embodiment, the radiation exposure may be estimated exposure levels based on personnel position within estimated radiation scatter, but actual radiation exposure measurements may alternatively or additionally be used. The benchmarks may include any type or kind of measure including, but not limited, averages, medians, modes, maximums, minimums, ranges, predictions, combinations thereof, or the like.
The analytics subsystem 408 and/or the intervention subsystem 410 may be configured to determine where one or more particular procedures has met, not met, exceeded, or fallen short of one or more benchmarks, such as by a predetermined amount, and the intervention subsystem 410 may be configured to initiate one or more appropriate interventions. These benchmarks may be average, median, modes, maximum, minimum, or other measure of estimated or actual exposure levels for similar cases. Similar cases may be where, for example without limitation, the same or similar procedures are performed, the same or similarly situated operators performs the same or similar procedures, the procedures are performed at the same hospital or practice, within a given geographic area, and/or on similarly situated patients, where the same or similar techniques and/or devices are used, combinations thereof, or the like. Similarly situated operators may be those having the same level of experience, certification, training, combination thereof, or the like.
Where a benchmark is met, not met, exceeded by a predetermined threshold, combinations thereof, or the like, one or more interventions may be initiated. The analysis and/or interventions may be initiated during a procedure, during post-operative review, or periodically, such as during quarterly, annual, etc. reviews. For example, without limitation, the interventions may include providing the operator or other personnel with access to medical literature, training videos or information, educational opportunities, auditory or visual feedback, audio and/or visual communication with another operator or medical staff, combinations thereof, or the like. Such access may be facilitated by way of one or more reference databases 416 integrated with, or remote from and in electronic communication with, the intervention subsystem 410. In exemplary embodiments, during a procedure if a benchmark exposure level is met, not met, exceeded, or fallen short of, this may indicate that the procedure is more complex than anticipated and/or that the procedure is not progressing as expected. An audible or visible indicator of the same may be generated by a notification subsystem 418, such as at the AR tracking devices 46, the projection devices 62, the electronic display 72, the remote devices 424, a speaker, combinations thereof, or the like. The audible or visible indicator may alert the personnel to the unanticipated complexity and/or progress (or lack thereof). Options to access training or educational materials, such as those stored at the reference databases 416, may be provided, such as at the AR tracking devices 46, the projection devices 62, the electronic display 72, and/or the remote devices 424, to facilitate further case progress, either in substantially real-time or post-operative such as for further training and education. Such training materials may provide latest or alternative techniques, equipment available for use in such procedures, combinations thereof, or the like. Alternatively, or additionally, virtual consults with other operators, medical staff, technical support representatives (particularly in the case of operating certain medical devices) may be provided such as at the AR tracking devices 46, the projection devices 62, the electronic display 72, and/or the remote devices 424, by way of one or more communication subsystem 420. The communication subsystems 420 may be integrated with, or remote from, the intervention subsystem 410.
