What is the term for the motion of the patient that leads to decreased detail during the exposure?

The term that refers specifically to the motion of the patient that leads to decreased detail during the exposure is patient movement. When a patient moves while images are being captured, it can result in blurring or a loss of sharpness in the image. This movement can occur during any part of the imaging process, which may be due to discomfort, anxiety, or inability to remain still.

While voluntary movement describes actions that a patient consciously decides to take, and involuntary movement includes motions like twitching or breathing which cannot be controlled, the broader term "patient movement" encompasses both scenarios and directly addresses the issue at hand. Static motion, on the other hand, refers to a lack of motion, which would not contribute to decreased image detail. Therefore, patient movement effectively captures the overall concept of any motion that causes image degradation during exposure.
