OBJECTIVE: The recent acquisition of the first-ever hand radiography in low Earth orbit marked a milestone for X-ray imaging in space, motivating further research for the development of space-adapted devices. This review intends to provide an overview of the current state of X-ray imaging technologies for space applications, analysed within the framework of astronauts' healthcare assessment, highlighting the role of medical physicists in advancing this field.
METHODS: An initial search was conducted on PubMed using keywords related to radiography and spaceflight. A further selection was performed by screening the reference lists of pertinent papers that emerged in the initial search.
RESULTS: This review shows medical conditions that may pose risks to astronauts during spaceflight and could benefit from X-ray imaging for diagnosis or treatment. Currently available technology for in-flight X-ray imaging is presented. Gender-specific aspects have been considered. Critical aspects identified include device limitations, sources of image deterioration, the need for quality assessment and dosimetry studies.
CONCLUSIONS: A strong interest in the use of radiography in space emerged. However, to date, only one radiographic image has been acquired in low Earth orbit. Further research is needed to identify adequate hardware and to investigate the feasibility, image quality, and radiation dose for in-flight radiographic imaging. Quality assurance procedures should possibly be adapted to the space environment. The role of medical physicists in this context is central, and specific attention to this field is desirable to address the challenges outlined.
