Quizplus · Accepted Answer

AEC systems are designed to adjust the exposure technique based on patient size, thickness, and density. In this case, the patient is cachexic and emaciated, which means that their body density is likely to be lower than average. Allowing the AEC system to adjust the technique will help to compensate for this, resulting in an image with optimum quality. Raising the kVp would not necessarily benefit the image quality in this case, as it would increase the risk of scatter radiation and decrease contrast resolution. Raising the mAs would lead to an increase in patient dose, and decreasing the SID would also affect image quality.
