Question

Quizplus · Accepted Answer

For an AP erect abdomen projection, the patient should be upright for a minimum of 5 minutes before imaging to allow gas to rise and the bowel to settle, resulting in better visualization of abdominal organs. Collimating to the level of ASIS may be necessary for proper positioning, but it is not a factor specific to this projection. A higher kV technique may be used for larger patients or to minimize scatter radiation, but it is not a requirement for this projection. Increasing the SID to 72 inches may help reduce magnification, but it is not practical in most clinical settings and not necessary for this projection.
