The process was detailed in a recently published study in the journal Radiology, and focuses on last year's Fram2 mission. Instead of days of medical training, astronauts spent only four hours learning how to use their portable radiography device. They then took preflight X-rays of a hand, forearm, chest, abdomen, and pelvis ahead of their SpaceX Falcon 9 rocket launch on March 31, 2025. Once in orbit, the team calibrated the system before testing their MinXray on the same body parts as well as a smartwatch.
Once the crew returned, a trio of independent radiologists reviewed the orbital X-ray images based on their positioning, spatial and contrast resolutions, and general scan quality. Although positioning scores were slightly decreased for the central body images, every other scan held up to similar examples created on Earth. Meanwhile, the astronauts reported that using the machine was easy despite minimal prior coaching. Looking ahead, researchers hope to conduct further X-ray tests during orbital missions, while continuing to reduce the overall size of equipment.
