Final answer:
The option that might increase the possibility of motion artifacts is using no straps or pads for patient comfort, as lack of immobilization can lead to involuntary movements resulting in motion artifacts during imaging procedures.
Step-by-step explanation:
Among the options provided, the one that might increase the possibility of motion artifacts occurring during an imaging procedure is: using no straps or pad so that the patient feels comfortable and unrestricted. When patients are not properly immobilized, they may move involuntarily or voluntarily during the imaging process, which can cause motion artifacts and result in poor quality images. On the other hand, immobilizing the patient tends to reduce the likelihood of motion, leading to clearer images. Explaining the procedure to the patient can actually decrease the likelihood of motion artifacts by helping the patient understand the importance of remaining still. Using a helical scanning technique to acquire necessary slices in a single breath hold is also an approach that minimizes motion artifacts by reducing the scan time.
