Question

Quizplus · Accepted Answer

Taking the exposure on the second inspiration rather than on the first would improve the inspiration of lungs. This allows the patient to take a deeper breath and expand their lungs further, resulting in a better radiograph. Using a higher kV may not necessarily penetrate the diaphragm more, and a shorter exposure time may not allow the patient enough time to take a deep breath. Performing the chest position supine may not necessarily improve lung inspiration.
