Experiment Description

Research Overview
  • The ultrasound is the only medical imaging device currently available on the International Space Station (ISS). Ultrasound may have direct application for the evaluation and diagnosis of 250 medical conditions of interest for treating exploration crews.
  • This experiment demonstrates the diagnostic accuracy of ultrasound in medical contingencies in space, determining the ability of minimally-trained crewmembers to perform ultrasound examinations with remote guidance from the ground.
  • Crews traveling beyond Low Earth Orbit (LEO) need the telemedicine strategies this experiment investigates, should injury or illness occur in space. There are also widespread Earth applications for emergencies and rural care situations.

Previous Missions

ADUM is the first formal experiment to examine the use of ultrasound in microgravity. Crewmembers, however, did check out the ultrasound equipment during Increment 5.
