Abstract
After the lesion has been discovered in the ordinary diagnostic procedures, the patient is placed on the CT couch in a position similar to that to be adopted in radiotherapy, and the upper and lower limits of the region to be treated are determined and marked on the skin. Three lines — anterior, left, and right — are marked on the skin of the patient using the three light localizers attached to the ceiling and bilateral walls of the room. These lines are termed “positioning skin markers” and are parallel to the body axis (Fig. IV.10a).
