LATEST THINKING ON O.R. SCENARIOS FROM TECHNICAL REQUIREMENTS VIEWPOINT

 

The operating room hardware is constructed from the following elements, 
with specific items selected to meet the needs of each of the 
demonstration scenarios (note that wireless is advantageous for 
decreasing the complexity of the environment but not required):

 

           Existing video generating devices in O.R. (RCA video out and 
other options): laparoscope, overhead camera, room view

 

           Existing video generating devices in O.R.: DaVinci surgical 
system (several output options including two video streams – left-eye, 
right-eye) – surgical assistant today looks at only one mono-view on 
monitor over table while operating surgeon is at separate console with 
stereo viewing device and controls.

 

           Existing audio generating devices in O.R.: lapel microphone 
for surgeon

 

           Existing video display monitor (one) in O.R. (I think 
they’re RCA into a VCR)

 

           Head-mounted or hand-held displays for two users with 
head-tracking (each has to have their own view-point, but looking at 
the “same” content) for volume visualization

 

           Control system for head-mounted or hand-held displays 
(remote and/or local)

 

           Ambient audio play back (speakers) in the room

 

           Lapel microphone for assistant patched in

 

           Large format video display

 

           Control system for large format video display

 

           Compact AG node incorporating as many elements above as 
possible

           

Notes: The communication points with the O.R. and the radiology 
workstation will consist of Fixed Standard AG nodes, Stereo enhanced AG 
nodes, compute/visualization servers, and hand-held nodes selected 
depending on scenarios. These are each under separate development 
within the ABC Testbed project and/or under base AG Team funding so 
will not be addressed here at this time (the whole AG Project is 
essentially “assumed”!). Only specific addition in regard to above is 
this: for the “handheld” wireless solution to be used in Hospitals, 
Hospitals are likely to have the following infrastructure in place in 
time for us: Tablet PC device or similar wireless laptop running XP 
with Hospitals’ information system running on it native OR through 
citrix – this is significant in that if we create a dual boot device or 
use Windows or use small Mac running Citrix to create a portable node, 
we CAN issue the residents a single prototype machine on which they 
will be able to do all their usual work plus the ABC Testbed scenario!

 

 

 

LATEST THINKING ON ER SCENARIOS FROM TECHNICAL REQUIREMENTS VIEWPOINT

 

The field hardware is constructed from the following elements, with 
specific items selected to meet the needs of each of the demonstration 
scenarios:

 

compact, portable, battery-powered wireless high-resolution video 
camera.

 

fixed location, wire-connected remote controlled high-resolution video 
camera (perhaps two – one mounted IN ambulance for view of transport, 
one mounted ON ambulance for view of scene – perhaps one with “Velcro”)

 

prototype General Devices “Rosetta” signal processing device with 
multiple data inputs capable of interfacing with various camera types 
and multiple output interfaces capable of mating with various radios, 
cellphones, and satellite phones. (Depending on engineering, this may 
be an AG node as well – or just an extension of the fixed AG node at 
hospital)

 

conventional cellphone.

 

next generation (high data-rate) cellphone.

 

conventional EMS field radio.

 

next generation (high data-rate) data-capable radio.

 

satellite phone.

 

 

The hospital hardware is constructed from the following elements, with 
specific items selected to meet the needs of each of the specific 
demonstration scenarios:

 

CAREpoint EMS Workstation to: present video images; manage (decode, 
archive, re-transmit, etc.) those images; interface with various 
communications means; serve as an AG node.

 

conventional telephone line for cellphone and satellite phone 
communications.

 

conventional EMS field radio receiver.

 

next generation (high data-rate) radio receiver.
