The chest X-ray is the commonest diagnostic X-ray examination. Normally a frontal (anteroposterior) view is obtained. The patient stands facing thc photographic plate with the chest pressed to the plate, with bands on hips and elbows pushed out in front. The radiographer, the technician who takes the X-ray, asks the patient not to move, then to breathe in deeply and not to breathe out. This makes a blurred, unclear X-ray image less likely and improves the quality of the image, as it is casier to see abnormalities in air-filled (inflated) lungs than in deflated lungs.
