Final answer:
The most common source of artifacts in Computed Radiography (CR) typically arises from processing errors, scanner malfunctions, or issues with the imaging plate, along with operator errors like incorrect exposure settings or patient movement.
Step-by-step explanation:
The most common source of artifacts in Computed Radiography (CR) can be attributed to several factors, including but not limited to, processing errors, scanner malfunctions, or problems with the imaging plate itself. For instance, when an imaging plate is not erased completely, it can retain a 'ghost' image from previous exposures, resulting in a superimposed artifact on the next image. Moreover, dust or scratches on the imaging plate can lead to visible artifacts on the final image.
Additionally, technical mistakes made by the operator, such as incorrect exposure settings or patient movement during the procedure, can be contributing factors as well. It is crucial for radiologic technologists to adhere to proper procedures and regularly maintain equipment to minimize these occurrences.
