Ultrasound a diagnostic tool for space, sports and more

sed instructional presentation on the basics of ultrasound examination and examples of remote guidance. Remote guidance is presented in experiment-specific sections, comparable to visual case studies. "One video session walks you through basic positioning, and the next one might demonstrate how to image a bone," Dulchavsky said.

After the computer-based instruction, trainees participate in a hands-on session where they perform abdominal and musculoskeletal ultrasound scans. A video stream from the ultrasound device is split between the on-site monitor and the remote location. Watching the simultaneous video feed, the remote medical expert can see the trainee's ultrasound images. He or she uses voice commands to guide the operator into positioning the probe and fine-tuning the settings to produce clear, useful images. The hands-on sessions are designed to closely simulate ultrasound experiments performed in orbit.

After the initial training, ultrasound operators complete a one-hour refresher course developed by Dulchavsky's team, called the Onboard Proficiency Enhancement (OPE) program. The OPE employs multi-media instruction similar to the original computer-based training. ISS Expedition 9 crewmembers astronaut Michael Fincke and cosmonaut Gennady Padalka completed the OPE program before doing inflight ultrasound scans of the shoulder.

Dulchavsky says the program will soon be one of the medical tools used by the Detroit Tigers baseball club. In addition, the U.S. Olympic Committee recently announced a collaboration with Dulchavsky's group to create research protocols involving Olympic athletes.

"Our next challenge is to improve the speed and efficiency of diagnosing and treating injury," Dulchavsky said. "We have the opportunity now to expand ultrasound from the medical and hospital setting to include assessment capabilities for sports, emergency medical care and for under-served areas of the world."
