Wide exposure latitude is a benefit of which system of radiographic technique?

Question

Quizplus · Accepted Answer

Variable mAs/fixed (optimum) kVp system provides the best wide exposure latitude. In this technique, the optimal kVp is selected for the body part being imaged, while the mAs is adjusted according to the size and density of the patient to maintain a constant image receptor exposure. This allows for a wider range of acceptable exposure settings, resulting in better image quality with less variation in exposure. Fixed mAs/variable kVp and variable mAs/low kVp systems may also offer some exposure latitude, but they are not as effective as variable mAs/fixed kVp. Fixed mAs/fixed kVp systems provide the least amount of exposure latitude, making it challenging to adjust the technique for variations in body size and density. Hence, the correct answer is D.
