For the first time in history, scientists have successfully captured X-ray images of a human directly in Earth’s orbit. The experiment demonstrated that a portable digital X-ray system can function effectively in microgravity conditions.
This was reported by RSNA.
The study was conducted during the 3.5-day polar orbit flight of the Fram2 spacecraft.
The crew utilized a commercially available portable digital X-ray system, which had been previously tested on Earth. Prior to the flight, participants underwent only a four-hour training session, after which they independently performed X-ray imaging in space.
The resulting images were compared with those taken before the mission’s launch.
Researchers determined that the quality of the X-ray images obtained in space was virtually comparable to those taken on Earth.
Radiologists did not identify significant differences in the clarity, contrast, or overall quality of the images. The sole challenge encountered was the proper positioning of the individual during the imaging of the central body part, as this is considerably more difficult in a weightless environment.
In addition to medical diagnostics, the system was tested for equipment inspection.
The X-ray technology allowed for a highly precise examination of the internal structure of technical devices without the need for disassembly. Upon returning to Earth, the equipment remained fully functional, despite minor damage sustained during the spacecraft’s re-entry into the atmosphere.
The authors of the study emphasize that during extended space missions, particularly voyages to the Moon or Mars, astronauts may require rapid diagnostics for fractures, injuries, or other medical conditions.
Until now, ultrasound imaging remained the primary method for visual diagnostics in orbit. The integration of X-ray capabilities significantly expands the possibilities for medical assistance in space.
Concurrently, scientists note that before implementing such systems in regular space missions, it is essential to refine the methodologies for operating in microgravity and to standardize the image acquisition process.
Recall that in space, the human heart rapidly loses mass due to the absence of gravity and reduced workload. After a 10-day mission, the heart’s main chamber decreases in size by an average of 12%. This is a natural adaptation of the body. Upon returning to Earth, there is a risk of dizziness and fainting due to reduced blood volume. For long-duration flights, such as a mission to Mars, effective preventive measures and training are necessary.
