To minimize motion unsharpness, which of the following methods is considered acceptable?

Minimizing motion unsharpness is essential for obtaining high-quality images in radiography and similar fields. Each of the techniques mentioned plays a valuable role in achieving this goal.

Suspended respiration is an effective method to reduce motion caused by breathing. By instructing patients to hold their breath during the exposure, the likelihood of movement during the image capture is significantly decreased, leading to sharper images.

Short exposure time is another crucial strategy. Reducing the amount of time that the imaging detector is exposed to potential motion (from either the patient or the surrounding environment) minimizes the chance that any movement will result in unsharpness. Quick image capture helps to freeze any small movements that may occur.

Patient instruction is just as important. By clearly informing the patient about what to expect and what they need to do during the procedure—such as remaining still or holding their breath—they are better prepared to comply, thereby reducing the risk of motion-related issues.

Given that all these methods complement each other effectively, their combined use represents a comprehensive approach to minimizing motion unsharpness in imaging. Thus, recognizing that all these methods contribute significantly to image quality justifies the choice of selecting all of them.
