What must be sterilized in radiology?

In radiology, it is crucial to ensure that any reusable instruments, such as adjuncts like XCP (extension cone paralleling) devices and beam alignment tools, are properly sterilized. These instruments come into direct contact with the patient during the imaging process, which poses a risk of cross-contamination and infection if they are not adequately sterilized between uses.

Being able to sterilize these adjuncts effectively helps maintain a safe environment for both patients and operators, reducing the likelihood of transmitting pathogens. Other items, such as X-ray films and protective barriers, are typically single-use or designed to prevent contamination and do not require sterilization in the same manner. Adjacent tissues are also not considered to be sterilized, as the focus is on minimizing exposure and infection risk through proper techniques.
