## Background
CROSS-REFERENCE TO RELATED APPLICATION(S)
The present application derives priority from U.S. provisional application Ser. No. 60/496,395, filed Aug. 20, 2003.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to video imaging systems and, more specifically, to a mobile video imaging, video communication and video production (VCVP) system designed specifically for the health care industry that provides high-resolution interactive audio, video and data communications between hospital operating room/procedure room environments and other remote locations for education, consulting, surgical assistance, diagnostics, demonstrations, and the like.
2. Description of the Background
There are many geographic areas where rural physicians and health practitioners need continuing education, and possibly real-time guidance from experts in carrying out various surgical procedures, etc. Unfortunately, distance and limited resources make it increasingly complicated for providers to furnish these services. This is especially true for military medics who often need education or guidance on certain procedures in the field. The problem has prompted many efforts to provide education and or real-time assistance via videoconferencing and even remote robotic surgery. Unfortunately, these efforts piece together existing hardware and fail to offer a solution that is economical, productive and cost effective in the various situations which would benefit.
Situations calling for real-time assistance are quite apparent, for example, an army medic who needs to perform an unfamiliar procedure in the field. There are also numerous situations where video production services are required in a medical setting, including academic surgical procedural programs to be used in teaching students, or surgical procedural/promotional programs for medical devices, instructional & assembly programs for mapping out the steps for assembling or using a complicated apparatus, seminar & workshop capture, patient education programs & documentary, sales force motivational programs, etc. Indeed, many surgeries are now broadcast by live event video production and internet broadcasting or satellite uplink. Both recorded program production as well as live event productions require extensive production overhead.
Unfortunately, the army medic has no ready solution. Medical production services are available, but usually in the form of a conventional video crew. The crew equip an operating room with video cameras, microphones, video switchers, audio mixers, both preview and viewing monitors, hundreds of feet of cables, and they record or broadcast the surgery. The work product of the various cameras and crewmen may be broadcast and recorded in real time or turned over to an editor for mixing, editing, to generate a final edited master recorded on tape/digital tape/CD/DVD, etc.
There have been few attempts to consolidate the process in the surgical setting to make it less obtrusive, more flexible in serving all the foregoing needs, and more economical to health care providers. One effort is described in United States Patent Application No. 20030142204 by Rus, Steven H. filed Jul. 31, 2003. This application discloses a surgical lighting control and video system that gives a user access to multiple devices at one station and makes control of the system simpler and more intuitive. A graphical LCD display is used to control a plurality of devices, such as overhead lighting, ambient lighting, cameras, and other operating room accessories. A voice interface allows the surgeon to adjust lighting and other aspects by simply speaking. A foot pedal interface and an infra-red remote control interface grant the surgeon control of the cameras, enabling direct control of rotate and zoom functions of the camera.
Surgeons generally are not capable or willing to attend to all of their own video video imaging, production and communications needs themselves while indisposed with a patient. A better solution would be a mobile video imaging, video communications and video production system capable of being manned by a single trained person. In the context of surgical imaging, such as system must provide high-resolution interactive audio, video and data communications between hospital operating room/procedure room environments and other remote locations for education, consulting, remote surgical assistance, diagnostics, demonstrations, and the like.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a mobile video imaging, video communication, video production (VCVP) system designed specifically for health care and surgical video imaging and suitable for operation by a single trained person which provides a complete array of audio and high-resolution video capture tools, mixing and editing tools, recording capabilities to a variety of common analog and digital formats, and real time video and data communications capabilities for networked communications for teleconferencing between hospital operating room/procedure room environments and other remote locations for education, consulting, remote surgical assistance, diagnostics, demonstrations, and the like.
It is another object to provide a mobile VCVP system as described above which is contained in a portable base with fully articulating boom-mounted video camera for high-resolution close-up imaging in any health care arena (such as an operating room).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention is a mobile communication and video production (VCVP) system designed specifically for surgical imaging that provides high-resolution interactive audio, video and data communications, production and recording capabilities at hospital operating room/procedure room or field environments for transmission to other remote locations for education, consulting, surgical assistance, diagnostics, demonstrations, and the like.
FIG. 1 is a front perspective view of the mobile VCVP station 2. Mobile VCVP station 2 generally comprises a multi-camera video and control system (to be described) mounted on a mobile platform 50, an array of video production equipment inside the platform, an array of teleconferencing and networking equipment inside the platform, and a fail-safe battery system in the platform for powering the foregoing.
The platform 50 includes a fully-articulating telescoping boom 4 mounted atop a support mast 6, which is in turn mounted atop a wheeled cabinet. The camera and control system includes a plurality of remote control Pan-Tilt-Zoom cameras (at least two are preferred as in the illustrated embodiment . . . 10A, 10B), one camera of which (10A) is mounted at the end of the boom 4 for overhead images of healthcare procedures. The other remote control Pan-Tilt-Zoom camera 10B is mounted along the mast 6 to provide a full view of the clinical team or entire operating room. Both remote control cameras 10A & 10B are mounted on adjustable camera heads 8, 9, respectively, including quick-release brackets to supplement their inherent remote control pan/tilt/zoom capabilities. Both remote control cameras 10A & 10B are controlled by fixed controls mounted on mobile platform 50 or by wireless remote controls, and their outputs are coupled both to the video production equipment as well as the teleconferencing and networking equipment inside the platform 50. In addition to remote control cameras 10A & 10B, the fixed controls, remote controls, video production equipment and networking equipment in platform 50 are capable of handling additional cameras if desired. Specifically, using the equipment described below the camera and control system may accommodate up to four Pan-Tilt-Zoom cameras. Moreover, the video production and communication equipment inside the platform 50 includes a plurality of auxiliary inputs for connection of external (remote) endoscopes, laparosopes, or other medical imaging devices or remote video cameras as desired to completely capture a given surgical procedure. The system also includes a wireless microphone and wireless receiver/transmitter. This combination of video/audio sources facilitates the complete and unobstructed capture of surgical procedures from multiple selectable angles and proximities, all from a singular point of control.
The mobile VCVP station 2 is designed to be manned and controlled by a single operator (rather then a full production crew as typically required using conventional means), and for this the camera control system includes an operator console with controls 40, and a preview panel 30 comprising a plurality of small color monitors pivotally mounted on the mast 6 for operator previewing. In addition two full size color monitors 20A & 20B are pivotally mounted on the mast 6 above the preview panel 30 to allow previewing by the operator or others and a view of the far side participant(s). The boom 4 and mast 6 stem from a work surface 51 atop the mobile platform 50, beneath which a cabinet enclosure houses an array of video production and teleconferencing equipment to be described. The cabinet enclosure includes two sets of doors 52, 54 for access to a rack-mount support assembly for housing all the video production and communications equipment in a vented dual-column environment overtop the power supply. Generally, the back door 52 provides access to the patch panel, speaker system and power supply, while the front door 54 provides access to video production equipment that provides the real time capability to make recordings to a hard drive, or Mini-DV, S-VHS, VHS and DVD format recordings for the surgeon to leave with if desired, and to and communications (teleconferencing) equipment. The platform 50 is supported on heavy-duty locking castors 56 for mobility.
FIG. 2 is a perspective view of camera 10A mounted at the end of the boom 4 for overhead images. Camera 10A is presently a model PC110R1 Elmo video camera mounted on the snap-in receptacle of a professional camera head mount 8. A Bogen Manfrotto® 3262 camera arm wi snap-in receptacle is presently preferred. The camera 10A is connected by conventional cables coupled by a male connector 102, the cables running the length of boom 4. Referring back to FIG. 1, a preferred camera 10B is an Elmo model PC110S which may be pivotally mounted on a yoke bracket compression fit directly on mast 6. If desired, camera 10B may also be mounted on an optional camera head mount 9 although this is not so necessary because camera 10B is primary intended for wide angle viewing. The camera switching and control circuitry (to be described) is capable of controlling as many as four remote control cameras, and so additional cameras may be attached to mast 6 or boom 4 as desired.
FIG. 3 is a perspective view of the operator console with controls 40, and a preview panel 30 comprising a plurality (here four) of small color monitors pivotally mounted on the mast 6 for operator previewing. The controls 40 sit atop work surface 51 on the mobile platform 50. The Elmo cameras 10A, 10B described are commonly controlled by a hardwired camera controller 142 which controls the pan/tilt/zoom/focus/iris functions for up to four cameras. A suitable camera controller 142 is the Telemetrics, Inc. Model CP-ITV-VCC-4 with joystick control. Additionally, remote control of the cameras 10A & 10B is possible with a wireless remote controller 144, which may be an infrared camera remote control by Elmo RCW-PTZS. A video switcher keypad 143 provides push-button selection of the active camera (one of up to six in the illustrated embodiment), and provides blinking indicator LEDs designating the currently-active camera. A suitable video switcher keypad 143 is the Extron Model KP-6. Optionally, a video mixer can be used in place of the video switcher keypad 143 to allow fades and transition effects when changing active cameras. Remote control 172 is also provided for the video conferencing codec 86, remote 174 is provided for a combination VHS/MiniDC video tape recorder 72, and remote 145 for a combination optical media recorder 74 (all to be described).

The active broadcast monitor 132 is likewise mounted on a display bracket attached by a yoke compression fitting to the mast 6, just above the mini-display panel 131.
In addition to the operator console with controls 40, two viewing monitors 20A, 20B are likewise attached by a bracket and yoke compression fitting to the mast 6, just above the active broadcast monitor 132, these two main monitors allow the immediate surgical team to view the audience on the far side of a teleconference, as well as the video feed being broadcasted to that audience. Suitable viewing displays 20A, 20B are Panasonic Model TC1701 17′′ diagonal LCD TVs held together on a single adjustable bracket.
FIG. 4 is a close-up view showing the bracket 152 for attaching the two viewing displays 20A, 20B to the mast 6. Bracket 152 spans both displays 20A, 20B with an outstretched crossbar that secures the displays 20A, 20B at the sides. The camera head 9 for mounting camera 10B to the mast 6 is also shown. Bracket 152, camera head 9 and mini-display panel 131 (all other fixtures to mast 6) are made using yoke compression fittings 153 which grip the mast 6, all of the yoke compression fittings 153 being substantially uniform. Each yoke compression fitting 153 is an aluminum collars that is hex-screwed together around the mast 6 to anchor the respective components to the mast.
FIG. 5 is a side view of the mobile VCVP station 2 with open back door 52 to reveal the mast 6 configuration. The mast 6 is a height adjustable 2′′ diameter stainless steel tube that penetrates the work surface 51 through a pre-cut hole therein. The mast 6 is slidably supported in a yoke inside the mobile platform 50, and is locked at a fixed vertical position by lock knob 116. Referring back to FIG. 1, the boom 4 comprises three telescoping sections of aluminum tubing which telescope from approximately 5 to 15′. The boom 4 is horizontally attached to mast 6 at a T-junction 148 which preferably includes a Teflon collar-insert in its upper extent which serves as a bushing to allow easy sliding deployment.
To assemble the mobile VCVP station 2, a user will first slide the mast 6 into the pre-cut hole in surface 51 and into the yoke inside the mobile platform 50, where it is locked at a fixed vertical position by lock knob 116. The mini-display panel 131 is then secured to the mast via a yoke collar 153. The active broadcast monitor 132 is then secured to the mast via a yoke collar 153. The dual viewing displays 20A, 20B are then secured to the mast via two yoke collars 53 and bracket 152. The mast camera mount 9 is secured to the mast 6 by a yoke collar 53, and the Elmo camera 10B is secured thereto by quick-release plate. Next, the T-junction 148 is slidably inserted onto the top of the mast 6. The boom 4 is inserted into the T-junction 148. The Elmo camera mount 8 is secured to the boom 4, and the Elmo camera 10B is attached and secured to the boom 4 (likewise by quick-release plate). All electrical components are then wired-up, and all wires are labeled to expedite this. The wiring connections are described in detail with regard to FIG. 8. The system 2 is now fully assembled.
In use, the mobile VCVP station 2 is wheeled and parked (by locking castors 56) at a convenient unobtrusive location in an operating room or other environment. The mast 6 is pivoted to angularly position the boom 4 as desired, and the telescoping boom 4 is extended to position the camera 10A directly overhead the operating site. Likewise, camera 10B is adjusted to give a full view of the surgery. These adjustments are further facilitated by positioning the camera heads mounts 8, 9. With cameras in place, the operator pivots his preview panel 30 over the controls 40, and pivots the two full size color monitors 20A & 20B to provide the surgical team or other onlookers with preview capability. As the surgery proceeds, the operator can multiplex the camera signals and produce a live high resolution video and audio feed that is networked in real time for teleconferencing, and/or recorded in any known format such as Hard Drive, Mini-DV, S-VHS, VHS and DVD. All of the foregoing is powered by the internal dual-battery supply, making the platform completely mobile and self-contained such that it can be repositioned in any venue.
Each time the system 2 is rolled from one location to another it is imperative to remove the video and power cables from the boom camera 10A, remove the boom camera 10A from boom 4, remove boom 4 from T-junction 148, and lower the mast 6 to clear any doorway. Once the system 2 is in its new location, the castor wheels 56 should be locked.
FIG. 6 is a front view of the mobile platform with open front doors 54 providing access to video production equipment that provides the real time capability to record to a hard drive, or make Mini-DV, S-VHS, VHS and DVD format recordings for the surgeon to leave with if desired, and to communications (teleconferencing) equipment.

The power input to battery charger 188 is connected to a standard isolation transformer 183 (for surge protection) to a standard wall outlet. A suitable power supply/charger 188 is the Intella Model PCS-2201 trickle charger. The batteries 182 are safety sealed to prevent leakage in a surgical environment. The batteries 182 are also connected to a conventional 12 vdc distribution panel for coupling all 12 vdc equipment described above. In addition, the batteries 182 are connected through a conventional 120 vac power inverter 185 for AC conversion, which in turn is connected to an AC power strip 189 for coupling all 120 vac equipment described above.
It is noteworthy that the regulated power supply/battery charger 188 and power inverter 185 can be combined in a single device (combination regulated power supply/battery charger/power inverters being readily available). In this instance the power-strips 189 are connected directly to the combination regulated power supply/battery charger/power inverter.
To use the system 2 in real time for teleconferencing, the video conferencing codec 86 must be programmed and networked in accordance with the manufacturer instructions (e.g., Polycom, Inc.).
During installation a technician will program the video conferencing codec 86 to operate in the particular IT environment as necessary, inclusive of all network info. This is done by a display screen on the codec 86. A graphical menu allows the user to set the following parameters.
WINS Resolution—allows codec 86 to be resolved to an IP address in a routed environment. When this option is selected, the codec 86 sends requests to the WINS server for WINS name resolution.
DHCP—The Dynamic Host Configuration Protocol allows a server to dynamically assign IP addresses to devices on a LAN. The DHCP option can be set to Off, Client, or Server. When Off is selected, the IP address, DNS servers, default gateway, subnet mask, and WINS server information must be entered as static addresses. These addresses are permanent until they are manually changed. When the Client option is selected, the user's DHCP server automatically assigns an IP address, a DNS server address, a default gateway, a subnet mask, and a WINS server address. When Server is enabled, the options IP Address, DNS Servers, Default Gateway, Subnet Mask, and WINS Server cannot be changed.
DNS Servers—DNS servers are computers which translate domain names (example: ww.polycom.com) into IP addresses. If the DHCP Client option is selected, the DNS server addresses are automatically filled in and you cannot make any change to this field. If the DHCP Off option is selected, the DNS server addresses must be entered manually.
Default Gateway—The default Gateway is a router on the local network. Its main task it to act as an interpreter between two systems that do not use the same communications protocol, data formatting, and other network functions. Your system must go through this router to access destinations outside of its network.
If the DHCP Client option is selected, the Default Gateway address is automatically filled in. If the DHCP Off option is selected, the Default Gateway address must be entered manually.
