title: An analog patient model derived from computed tomograms for three-dimensional radiotherapy planning.
abstract: An analog model of the part of a patient's body containing a tumor is constructed by drawing anatomical contours obtained from computed tomograms on a set of transparent plastic sheets. The coverage of radiotherapy fields in the patient is visualized in three dimensions using the model and the light beam from the radiotherapy machine or a simulator. A clinical example is presented.
