position, inspiration, exposure, rotation(English)

• refers to 4 items: 1) position: is this a supine AP file? PA? Lateral?; 2) inspiration: count the posterior ribs. You should see 10 to 11 ribs with a good inspiratory effect; 3) exposure: well-exposed films have good lung detail and an outline of the spinal column; 4) rotation: the space between the medial clavicle and the margin of the adjacent vertebrae should be roughly equal to each other; look for indwelling lines or objects
