1 Crew Medical Information System (CMIS) VR and Medicine Integrated for Medical Care for Long-Duration Spaceflight Kevin Montgomery PhD Mihriban Whitmore PhD, MG Sriram PhD, Suresh Sainath

2 The Scenario Long-duration spaceflight (this means going to Mars- 2035): 6 month trip, years on surface, 6 month return 5 Crew members- 1 Chief Medical Officer Millions of miles from nearest hospital Extremely hazardous environment Constant physiological and psychological transformations High stress/high visibility/$50b+ on the line You can t t even call for a consult (7-22 min RTD) No pressure!

3 What you will need Ability to maintain surgical skills and acquire new skills in absence of real patients Ability to plan and train for surgical procedure Database of human anatomy Step-by by-step instructions for any procedure Computer-based assistance to perform surgery Advanced diagnostic devices Integrated medical information management system

4 What you will need Ability to maintain surgical skills and acquire new Surgical Simulators skills in absence of real patients Ability to plan and train for surgical procedure Surgical Planning Systems Database of human anatomy Step-by Anatomical by-step instructions Databases for any procedure Computer-based Intraoperative assistance Assistance to perform Systems surgery Advanced Advanced diagnostic Medical devices Devices Integrated medical information management system Medical Communications Infrastructure

5 What we ve been working on Surgical Simulators Surgical Planning Systems Anatomical Databases Intraoperative Assistance Systems Advanced Medical Devices Medical Communications Infrastructure

6 Space Station Intranet Autonomous Medical Care Optional link to Intranet System (AMCS) Access Point 9 Collaborators: JSC (Space Medicine, Engineering), Wyle, ARC, Stanford, Cleveland Clinic 9 Various Data Sources supported: Physiological and Environmental Sensors, Video (wired/wireless), GPS 9 Various Client Devices supported (Pocket PCs, HMDs, Laptops, PCs) 9 Local ad-hoc Networking using SwitchBoard/MCIA 9 Ad-hoc Network can be connected to Intranet as soon as Access Point is in range, as well as Internet 9 Compatible with most Wireless LAN Technologies (RangeLAN2, b, Bluetooth) 9 Low Bandwidth Requirement (128-kbps S-Band compatible) 9 Modular, Flexible, Reliable, and Secure Switchboard/MCIA Wired or Wireless connections MEC TNG Crew Medical Interface System LifeGuard Physiological Monitors Wireless Streaming Ultrasound Wireless Video Camera WIS Environmental Monitors Downlink (S-Band or Ku-Band) Internet Client Wireless Video Server Video Server Access Point JSC Intranet ipaq Client Stanford University, NASA Ames,

7 Crew Medical Interface System CHeCS (medical equipment rack), MCIA, cue cards are in another part of station- takes too long to move a person during emergency Need optimized, easy-to-use, hands-free (voice i/o), wireless system to access data, procedures, etc. Crew Medical Interface System

8 Terrestrial Applications During surgery, surgeon s s attention must be diverted from field to obtain information Vital signs, CT films, endoscopic video Slows the flow of surgery, limits productivity Instead, bring data to doctor instead of doctor to the data Surgery would similarly benefit from an enhanced, optimized human-computer interface- a Head s s Up Display for a surgeon that provides all relevant data and ability to affect control

9 Needs Unobtrusive system for information access Vital signs, imagery, procedures, communications Lightweight, wearable, wireless Hands-free control of system Advanced visualization and analysis techniques Multimedia, computer models, etc Real-time analysis and advice Crew tracking

10 Integrated headset: Proposed System Monoscopic,, flip-up HMD Microphone/earplug combination Wearable computer Low power for long-term use Tracking Back-end system: Medical information system GDS/ISIS- diagnostic and procedural expert system

11 First Prototype system (2000) Integrated Headset: Sony Glasstron HMD variable transparency/see-thru thru Microphone/earphone Direct tethered to back-end system Back-end system: Voiceserver- custom embedded device Spring simulation software Streaming data via Switchboard

12 First Prototype Environment Integrated, real-time data: CT scans Vital signs Endoscopic video Computer models Virtual patient to practice on Voice I/O subsystem: Recognition- Dragon Systems Synthesis- AI DuPont Institute

13 First Prototype Demo

14 First Prototype Evaluation Used in OR on two surgical cases (craniofacial) Part of Discovery Health channel segment Results: Useful, usable system Yes, they did use it for the whole case and not tear it off Cable management of tethered system is a drag First prototype system was a lot of equipment to drag into OR We could really use a research OR Transparent HMD not as useful as monoscopic however

15 Next Generation System Integrated headset: Monoscopic HMD Wireless mic/earphone Wearable Computer: Wireless ipaq PDA doing video replication Completely untethered system Back-end system: Voiceserver embedded computer Workstation generating graphics Data from MCIA (medical and environmental data) and CHeCS checklists

16 Future steps Further development of system(s): CMIS, MCIA (uplink 2/05), GDS/ISIS, Lifeguard Integration/collaboration with other great folks Please let me know if you d d like to be one Evaluation and test Ground-based Flight

17 Summary Medical care on long-duration spaceflight requires advanced, integrated systems These systems are useful terrestrially as well We ve developed one such system as part of an overall information architecture: Provides for real-time data access (CT, vitals, video, etc) and procedural information Integrated simulation environment Hands-free interaction Integrates with expert system for diagnosis and treatment Useful for many tasks beyond those mentioned here
