What is a common characteristic of lateral sacrum projection concerning patient positioning?

A common characteristic of the lateral sacrum projection is that it varies based on the patient's size. This is important because the anatomy and body habitus of each patient can significantly impact how the radiographic image is obtained. For example, larger or heavier patients may require adjustments in positioning or the use of different equipment to ensure that the entire sacrum is adequately visualized in the image. This adaptability in technique is necessary for accurate imaging and diagnosis, as it allows the radiologic technologist to optimize the exposure factors and achieve the best quality images based on individual patient needs.
