Authors: Lee Jae Sung  , Kim Eomjun  , Park Kwang Suk  , Sung Mi Young  , Sung Myung-Whun  , Kim Kwang Hyun
Published: February 2025

We developed a new analysis technique for the assessment of irregular vibratory movement of vocal folds. Successive frames of pre-recorded video images from videostroboscopy were transferred to computer memory and vibratory track of one selected point was described as a waveform by displaying the same lines of all frames along the vertical direction. Glottal area waveform, which was normalized with glottal length, was composed to quantitatively assess the overall vibratory pattern of vocal folds. By applying this technique, irregular vibratory patterns of multiple regions, such as asynchronized registration of glottal cycles, could be easily visualized It would be possible to monitor and analyze the pathologic changes of vocal fold movement by means of this newly developed system.
A Marker-Free System for the Analysis of Movement Disabilities
Authors: Legrand Louis  , Marzani Franck  , Dusserre Liliane
Published: February 2025

A major step toward improving the treatments of disabled persons may be achieved by using motion analysis equipment. We are developing such a system. It allows the analysis of plane human motion (e.g. gait) without using the tracking of markers. The system is composed of one fixed camera which acquires an image sequence of a human in motion. Then the treatment is divided into two steps: first, a large number of pixels belonging to the boundaries of the human body are extracted at each acquisition time. Secondly, a two-dimensional model of the human body, based on tapered superquadrics, is successively matched with the sets of pixels previously extracted; a specific fuzzy clustering process is used for this purpose. Moreover, an optical flow procedure gives a prediction of the model location at each acquisition time from its location at the previous time. Finally we present some results of this process applied to a leg in motion.

Authors: Wiedemann Timm  , Knaup Petra  , Bachert Andreas  , Creutzig Ursula  , Haux Reinhold  , Schilling Freimut
Published: February 2025

In the past 20 years considerable progress was made in pediatric oncology concerning the results of therapy in Germany. Nationwide multicentre trials provide protocols for the therapy of the children. The calculation of the chemotherapy according to the protocols is rather complex and the documentation efforts for the pediatricians are enormous. Thus, we developed as a first step an application system for Computer Aided Therapy Planning In Pediatric Oncology (CATIPO), that is in routine use in about 20 pediatric clinics in Germany. In order to support the physician comprehensively with the documentation that is necessary for the trials we currently develop a Documentation System for Pediatric Oncology (DOSPO) that comprises the functionality of chemotherapy planning according to the protocols released by the trial centres. Besides supporting the physician in clinical routine the major objective is to improve the quality of the documented data. To reach this aims DOSPO combines research aspects of decision support and clinical documentation: formal representation of general protocols, calculating of a particular therapy for a patient, data acquisition, communication interfaces for transferring the data to the trial centres. In order to support trial centres an authoring system and a central data dictionary will be developed. This will enable the trial centres to develop new modules for trial-specific data acquisition in the clinics.
The Application of Model-based Complexity Inference Method to Molecular Evolution Analysis
Authors: Ren Fengrong  , Hiroshi Tanaka  , Okayama Toshitsugu  , Gojobori Takashi
Published: February 2025

In this study, a new method based on the concept of complexity in inductive inference is proposed for reconstructing molecular phylogenetic tree. This method describes the complexity of molecular phylogenetic tree by three terms, which are related to tree topology, the branch lengths and fitness between the model and data measured by likelihood function. The computer simulation is used to investigate the efficiency of this method. The results suggest that this method is superior to the traditional methods because it avoids excess-complexity in the tree model estimation available from DNA sequence.

It is argued that past evaluations have not been particularly informative in progressing the effective use of IT in healthcare due to their narrow focus. The different roles of evaluation in Clinical Informatics are examined, and the breadth and diversity of the available methodological tool kit highlighted The aim is to stimulate a greater awareness of the roles and methods of evaluation. Challenges in evaluation which face the Clinical Informatics community are discussed and finally some comments made concerning the way in which evaluation might be made more effective in order to improve our knowledge of how to deliver useful systems into healthcare.
Computer Experience and Computer Attitude: A Model to predict the use of Computerised Information Systems
Authors: Yaghmaie Farideh  , Jayasuriya Rohan  , Rawstorne Patrick
Published: February 2025

Computers are now essential technology in use by health workers. The literature shows that a number of factors effect the use of computers and many of them are related to attitude towards automation. Computer experience has been mostly used as a factor that effects computer attitude and its relationship with computer anxiety and computer use is not simple. Survey data from a study of 302 health workers, employed in a community setting was used to model the prediction of intention to use computers. The final model shows that ‘positive computer experience’ had a significant effect on computer attitude, computer anxiety and intention to use computers (both directly and indirectly). The model also confirms that those with a positive attitude towards computers had stronger intention to use computers. The value of these findings to health organisations in implementing automated systems is discussed.

VIRTUAL REALITY IN PSYCHOTHERAPY: THE MYTHSEEKER SOFTWARE
Authors: Rogers II McCagie Brooks
Published: February 2025

This chapter outlines the use in psychotherapy and medical diagnosis of an intelligent software system that helps clients to explore Personal Myth within virtual reality environments. Patented MYTHSEEKER software will allow clients to work with mythic analogues of lifeshapes and aspirations. This can help to focus therapy directions, find ways to participate with the person's world, and allow a kind of personal expression not previously possible. The software phases of assessment, facilitation, and enaction are described by which the client is assisted to explore systems of mythology or spirituality (called Depth Systems) that are traditional, ancient or newly-arising. The client builds a Personal Depth System representing Personal Myth, based on experiencing other Depth Systems, which can itself be experienced in the virtual environment This paper outlines our methodology and technology to realize these operations. Space limitations prevent further description in the present chapter of MYTHSEEKER software technology or psychotherapy scenarios of involvement.

Published: February 2025

30 volunteers were studied during bending tests : 16 healthy and 14 with idiopathic scoliosis. Geometry of computerized 3-D reconstruction in standing and lateral bending positions, compared to numerical simulation of the personalized FEM (Finite Element Model, including thorax and spine), showed coherence of the model to predicate the behavior of one healthy spine. The poor agreement for scoliotic spines highlighted the necessity of personalized mechanical characteristics to be introduced in the model. This study shows, for three given patient, effects of mechanical alteration of soft tissues in order to render the specific behavior of scoliotic spine.

Published: February 2025

The purpose of this study is to evaluate the effects of thoracic microdiscectomy(anterior release) and arthrolysis of costotransverse joint(partial resection of transverse process) as additional technique in posterior procedure for scoliosis. Subjects consisted of 11 idiopathic scoliosis patients (1 male and 10 females) aged 12 to 17 years(average:15.3), operated posteriorly using CD technique. The subjects were divided into 3 groups ; group A: three patients operated without release, group B: four patients with arthrolysis of costotransverse joint, group C ; four patients with microdiscectomy of three discs around the apical vertebra and arthrolysis of costotransverse joint, the average preoperative Cobb angle were, respectively, 56, 52 and 55 degrees. Cobb angle and disc wedge angle were measured. The correction rates of Cobb angle in the group A,B and C were 77%, 65%, and 53%, respectively. Improvement in the disc wedge angle was obtained especially in-group A. Microdiscectomy appeared to be effective to de-stabilize the thoracic curve. This additional technique provide excellent correction in one stage posterior procedure. Concerning to the arthrolysis of the costotransverse joint,more detailed study and biomechanical examination are needed for accurate evaluation.

Authors: Weiss Hans Rudolf  , Verres CH.  , Steffan K.  , Heckel I.
Published: February 2025

In our rehabilitation center scoliosis treatment consists of a daily postural education, lasting several hours. For pain therapy, we apply mainly physiotherapeutical methods with osteopathy, manual therapy, Mc Kenzie and Briigger. In addition we offer psychological help for pain relief. In case of severe chronic pain, we treat additonally with acupuncture. Pain therapy with medication is only performed in rare cases.The aim of the following study was to investigate the correlation between pain and scoliosis as well as short-term effects of pain therapy in scoliosis.In our database we have meanwhile 2.049 adult patients with scoliosis of different etiology (mainly idiopathic scolioses), who reported their pain level at the beginning and the end of a 3-6 week in-patient rehabilitation program. For this aim we used a visual analog scale (VAS), a numerical scale (NS), a standardized adjective scale (VRS) and a pain frequency scale. In addition, we correlated age and curvature angle according to Cobb with pain level and pain frequency. Patients with an average curvature angle according to Cobb of 38� and an average age of 29 years showed no correlation between pain severity and curvature angle, but there was a correlation between pain severity and the patient’s age. Before the in-patient treatment, 35% of the patients suffered no pain, after an in-patient treatment, 41% of the patients reported having no pains. AH scale values showed a highly significant decrease in the nonparametrical Wilcoxon-test.
Energy Status in Patients with Idiopathic Scoliosis
Authors: Tessakov D.
Published: February 2025

Energy system is one of the major communicating and regulating systems of the body. It has different parameters that characterize both normal and pathologic state of the organism. Idiopathic scoliosis (IS) is an irreversible disease that has a tendency to grow progressively worse. In this connection one can assume that the mode of IS development depends on, besides other factors, the condition of the energy status (ES) of the patient. The aim of the study was the investigation of the ES of the organism in IS for stating the possible prognostic parameters and assessment of the disease perspective. We have studied ES by means of measuring the electric activity of the acupuncture points in 62 patients aged from 8 to 14 years with IS in different stages. The control group consisted of 27 healthy persons of the same age range. The investigation of the patients was made according to a specially developed scheme. We measured the electric potentials in specific paired points. In the follow-up period (3-5 years) the clinico-radiographic dynamics of the deformity progressing was observed. All of the patients received conventional conservative treatment. The investigation of the healthy persons gave information about the condition of the normal ES depending on the period of pubescence. We revealed the ES types specific for prepuberty, puberty, postpuberty periods. These findings served as controls. We found different types of ES condition in the patients with IS depending on the stage and the character of the development of spine deformity. On the basis of the obtained clinico-radiographic findings we analyzed retrospectively the results of measuring electric activity of the acupuncture points. It gave us the opportunity to determine the energy criteria of prognosis for the disease development, when it was diagnosed at the early stages in growing patients. These findings are important for planning rational management program.

“HausTeleDienst” - A CATV-based Interactive Video Service for Elderly People
Authors: Stroetmann Karl A.  , Erkert Thomas
Published: February 2025

Since 1991, 17 elderly persons (aged 75 to over 90) in 15 households have been connected via TV-videophones to a service centre. A standard CATV network was modified to support a reverse channel. This has been world-wide the first fully interactive broadband video communications project implemented in a real setting and operating over an extended period of time. The overall aim has been to prove the ability of frail elderly and mobility-impaired persons to live independently, and to demonstrate strategies for reducing the load on social and health care service resources. Service components include remote care; information and assistance; emergency, counselling, training and exercise services. Practical experience, both from the side of the service provider and that of the users, is discussed. Simplicity of technical design and ease of handling contributed to a feeling of being empowered by the technology. In addition, the very personal and close relationship to the staff– which was strongly supported, not inhibited by the video communications– was a major factor in acceptance of the service. It proved a highly successful activity with a great potential for the future: In different contexts with newer technology, market trials are underway to commercialise this service.
Evaluation of a Canadian Telepsychiatry Service
Authors: Urness Douglas A.
Published: February 2025

A telepsychiatry pilot project linking five rural general hospitals and Alberta Hospital Ponoka was implemented in June 1996 as a response to both a scarcity of psychiatric resources in the Province of Alberta and the emphasis on community-based care. Psychiatrists located at Alberta Hospital Ponoka provided psychiatric consultations using videoconferencing technology in response to referrals from general practitioners. The project was evaluated through the use of questionnaires administered to consumers, service providers, and psychiatric consultants. Questionnaires were supplemented by interviews, site visits, logs, telephone interviews with consumers, and surveys to general practitioners at the rural sites.

A Pattern Catalogue of Surgical Interventions for Computer-Supported Operation Planning
Authors: Münchenberg J.  , Wörn H.  , Brief J.  , Hassfeld S.  , Mühling J.
Published: February 2025

In this paper we present a new operation planning system which was evaluated in the clinic for Cranio-Maxillo-Facial-Surgery at the University of Heidelberg. In opposite to commercial systems our goal was, that the system considers the complete surgical intervention and not only a single procedure of it. A second goal was, that the system enables managing of complex operations, independent of which way the intervention will be intraoperatively performed (without technical support, with passive navigation support or active support by robots). Our system supports the surgeon during the preoperative planning as well as during the intraoperative execution phase. Therefore we developed a course model by which the managing of surgical interventions is possible. The focus of this paper is on this course model. At first we introduce instruction graphs and describe the structure of each activity observing its attributes and their context. Additionally, various surgical scopes will be presented which enable the surgeon to select one view among different ones of the individual operation procedures in accordance to medical and technical knowledge as well as in accordance to different degrees of abstraction. At last we demonstrate operation patterns, used as expert knowledge.

Published: February 2025

Training of medical staff on minimally invasive surgery (MIS) is an area where new effective training methods are needed. We have studied stent grafting, a type of MIS, which is used to treat abdominal aortic aneurysm. Our analysis revealed that this procedure requires a range of motor, perceptual and cognitive skills. In this paper, we present a training environment that could be used to acquire these skills. Our proposed solution differs from the usual VR solutions by operating within the World Wide Web as an environment for our system. This paper discusses how our solution covers the training skills and presents the results of an appraisal process, which we conducted to evaluate our solution.

An Anatomical Atlas to Support the Virtual Planning of Hip Operations
Authors: Ehrhardf J.  , Handels H.  , Wegner T.  , Strathmann B.  , Plötz W.  , Pöppl S.J.
Published: February 2025

Two three-dimensional digitized atlases of a female and a male pelvis were generated to support the virtual 3D-planning of hip operations. Beside the anatomical labeling of bone structures the determination of orthopedic measures, like angles, distances or sizes of contact areas, is important for the planning of hip operations. Thus, each atlas consists of labeled reference CT data sets, a set of landmarks as well as definitions of orthopedic measures and methods for their automatic computation. Furthermore, methods for the automatic transfer of anatomical labels from the atlas to an individual data set are presented resulting in three-dimensional models of the patient’s bone structures. The anatomical atlases are designed to replace the interactive, time-consuming pre-processing steps for the virtual 3D operation planning.

Since 1990 the Romanian healthcare system has been crossing a stage of dramatic change. The healthcare reform, which is in progress, has structural, organizational and functional implications at the country level. The Ministry of Health is now preparing for the big IT changes. A Healthcare Management Information System (HMIS) will assure in the very next future automate data collection on health status of the population and on resource allocation and consumption. It is not an easy Way towards the use of the Data Warehouse concept and On Line Analytical Processing technology for creating and accessing the data repository. Therefore we decided to integrate existing applications related to health system indicators until the HMIS will assure a high performance analysis and data interpretation.

Automatic Skeleton Generation for Visualizing 3D, Time-dependent Fluid Flows: Application to the Virtual Aneurysm
Authors: Lee Daren  , Valentino Daniel J.  , Duckwiler Gary R.  , Karplus Walter J.
Published: February 2025

Intracranial aneurysms are the primary cause of non-traumatic subarachnoid hemorrhage. Difficulties in identifying which aneurysms will grow and rupture arise because the physicians lack important anatomic and hemodynamic information. Through simulation, this data can be captured, but visualization of large simulated data sets becomes cumbersome, often resulting in visual clutter and ambiguity. To address these visualization issues, we developed an algorithm that extracts a skeleton of the patterns in 3D, time-dependent blood flow. The algorithm decomposes the blood flow into “bare-bones” components that can be visualized individually or superimposed together to formulate an understanding of the flow patterns in the aneurysm.
Student-centered Distance Learning in Health and Medical Informatics
Authors: McCullagh Paul  , Duisterhout Joop  , Alexander Sylvia
Published: February 2025

Learning and teaching of health and medical Informatics is currently supported by web based material, which in the main has been derived from traditional texts. Aided by contributions from the expert community, the web site of the handbook of Medical Informatics has been developed to incorporate increased interactivity (with question and answers related to each section). This approach has proved beneficial to both student and teacher. To further increase the interactivity of the WWW we investigate the suitability of authoring tools for developing complex simulations and interactive tutorials, using an example from the area of quantitative decision support (Bayes Theorem). We propose that these tools provide a suitable platform for the preparation and delivery of collaboratively produced HMI courses, which address open and distance learning and pedagogic issues.

Published: February 2025

In many fields in histopathology diagnosis making is notoriously difficult. We explored the diagnostic process in the area of CL and related disorders. The field of cutaneous lymphomas (CL) and borderline lesions is complex and representative for the type of diagnostic problems encountered. A review of diagnostic support systems in diagnostic pathology revealed that the usefulness of these systems has been disappointing. We contribute this to the fact that these systems target only part of the diagnostic process.

Capitalizing on Knowledge for an Adaptive User interface
Authors: Ghédira Chirine  , Maret Pierre  , Fayn Jocelyne  , Rubel Paul
Published: February 2025

Hypermedia data browsing is a mean for improving information access. However, the overload and the heterogeneity of medical information, as well as the multitude of possible navigational paths, turn the consultation of data into a difficult task. We present in this paper a solution for the development of adaptive user interfaces in a hypermedia data browsing environment. It is based on the capitalization of the users knowledge in the decision-making process, expressed in terms of navigational paths and of data presentation modes that are customized to the user's preferences. This capitalization offers the user a way to reuse the cumulative experiences in browsing through patient records. We illustrate our approach with the implementation of HEMA, a clinical workstation prototype.

Building a Text Corpus for Representing the Variety of Medical Language
Authors: Zweigenbaum Pierre  , Jacquemart Pierre  , Grabar Natalia  , Habert Benoît
Published: February 2025

Medical language processing has focused until recently on a few types of textual documents. However, a much larger variety of document types are used in different settings. It has been showed that Natural Language Processing (NLP) tools can exhibit very different behavior on different types of texts. Without better informed knowledge about the differential performance of NLP tools on a variety of medical text types, it will be difficult to control the extension of their application to different medical documents. We endeavored to provide a basis for such informed assessment: the construction of a large corpus of medical text samples. We propose a framework for designing such a corpus: a set of descriptive dimensions and a standardized encoding of both meta-information (implementing these dimensions) and content. We present a proof of concept demonstration by encoding an initial corpus of text samples according to these principles.

Published: February 2025

Background: Retrieval tests have assumed that the abstract is a true surrogate of the entire text. However, the frequency of terms in abstracts has never been compared to that of the articles they represent. Even though many sources are now available in full-text, many still rely on the abstract for retrieval.

Authors: Nugent Chris  , Lopez Jesus  , Smith Ann  , Black Norman
Published: February 2025

The classification of the electrocardiogram (ECG) with Neural Networks (NNs) has proven to be a successful approach [1]. The objective of the current study was to develop prediction models to indicate the point at which training should cease for a given NN based ECG classifier and hence avoid the heuristic design process. Two prediction models have been generated; one based on NNs and one on Genetic Programming (GP). Following testing the NN exhibited no significant differences between desired and predicted outputs (p=0.306); the GP approach was just marginally significantly different (p=0.047).

Published: February 2025

The PACS system built and used in hospitals nowadays has quite significant overload on its central server because of both treatment of very large data and full management of medical images. We suggest a distributed communication and management methodology using PC to PC multicasting strategy for efficient management of medical images produced by DICOM modalities. It is absolutely necessary for reducing strict degradation of PACS system due to large size of medical images and its very high transport rates. DICOM PC to PC component is composed a service manager to execute requested queries, a communication manager to take charge of file transmission, and a DICOM manager to manage stored data and system behavior. Each manager itself is a component to search for requested file by interaction or transmit the file to other PCs. Distributed management and transformation of medical information based on PC to PC multicasting methodology will enhance performance of central server and network capacity reducing overload on them.
The Structure of Networks in Living Systems

Published: February 2025

It is known today there are many networks existing in living systems like signal transduction, transcriptional regulation, immanence response and like so on. These networks, like all the other networks, are based on relationships between elements. In this contribution, we propose a network model of living systems. It possesses information of connections among nodes, which stand for critical elements in a network. We formulate it as a simple model of probability theory and find interesting phenomena in it.

Published: February 2025

Health care professionals use more and more computerized systems in order to manage their work and the quality of care also relies on the improvement of cooperation between all the health care actors. Our ambition is to use new cooperation tools, in the context of the homecare, in order to facilitate coordinated cooperative work of health actors. We study the homecare activity, focus on its specificities, propose some specification for cooperation tool in such a context.

Published: February 2025

In the years 1975-1979, the longitudinal twenty years lasting epidemiological study of the risk factors of atherosclerosis in the population of 1419 middle-aged men was started. The main aims of the study were: to determine prevalence of the risk factors of atherosclerosis (RFA, i.e. smoking, obesity, hypertension, hypercholesteroaemia, family anamnesis), to follow up and to influence the development of RFA in order to decrease incidence and mortality from cardiovascular diseases (CVD).

Published: February 2025

Pathology beneath the highly reflective surface, such as the human retina, is key in the detection and management of disease. Advanced imaging techniques can help reveal these. Visualization and guiding the imaging to the appropriate area still remain as problems, in part due to the small scale of the pathology with respect to the potential area to be covered.

We developed a Virtual Reality Driving Simulator in order to safely evaluate and improve the driving ability of the handicapped. The Virtual Environment consists of 18 sections (e.g. a speed limited road, a strait road, a curved road, a left turn course, etc) and each section is linked naturally. For the interface of our driving simulator, an actual car was adapted for realism and then connected to a computer. We also equipped it with hand control driving devices especially adapted for the handicapped. A beam projector was used so that the subjects could see the virtual scene on a large screen which was set in front of them. The subjects selected for this trial were 10 normal drivers with valid driving licenses and 15 patients with thoracicor lumber cord injuries who had prior driving experience. For evaluation, 5 driving skills were measured including average speed, steering stability, centerline violations, traffic signal violations, and driving time in various road conditions such as strait and curved roads. The normal subjects manipulated the gas pedal and the brake with their feet while the patients manipulated a hand control with their hands. After they finished driving the whole course, the participants answered the questions such as “How realistic did the Virtual Reality Driving Simulator seeme to you?” and “How much was your fear reduced”. The five driving skills measured between the two groups (normal vs. handicapped) did not show any significant differences (p > 0.05). And in the three kinds of road conditions (a speed limited road and roads with a sharp curve and left-hand turn), the average speed of the handicapped group was 45.6 Km, less than 61.2 Km (p<0.05) of the normal group. In all, 11 patients (73%) reported that their fear of driving was reduced. Furthermore, their average score on the degree of realism question was 51.5%.

Authors: Seehusen A.  , Harrison A.
Published: February 2025

This research looks at the human ability to perceive haptic information when using Minimally Invasive Surgery (MIS) tools. In the simulation of MIS it is important to understand what haptic information can be perceived by a user. Understanding what can be felt allows the force feedback system of the simulator to be optimized.

Published: February 2025

The study and treatment of spinal deformities may lead to excessive doses of radiation for patients (especially children) examined by conventional X-ray radiology apparatus. In order to avoid this very crucial problem, a new X-ray radiology system has been devised. The new apparatus uses a high efficiency linear solid-state detector and highly sensitive electronics, operating in single X-ray counting mode (quantum mode). The scan parameters and image filtering are computer controlled. Data is acquired in real time by a high speed VME system. In this paper, the first images recorded using this new apparatus are shown. The main conclusion of the preliminary comparative dosimetric analysis is that it is possible to divide the patient’s dose by a factor of at least ten to one hundred with the quantum X-ray radiology apparatus.
