"Horizontal-beam lateral hip"
"Pelvic radiography"
"Lateral cervical spine"
"There are many different methods of performing the horizontal beam lateral hip projection depending on the patient’s ability to move and the equipment available. Many methods have an air gap present due to the position of the patient and image detector. Due to the thickness of the proximal anatomy, an anti-scatter grid may also be necessary for optimal scatter reduction."
