An important development in the area of simulation has been that of converting a CT scanner into a simulator. CT simulation uses a CT scanner to localize the treatment fields on the basis of the patient’s  CT scans. A computer program, specifically written for simulation, automatically positions the patient couch and the laser cross-hairs to define the scans and the treatment fields.The software (as part of CT scanner or a stand-alone treatment-planning system) provides outlining of external contours, target volumes and critical structures, interactive portal displays and placement, review of multiple treatment plans, and a display of isodose distribution. This process is known as virtual simulation.  圖文出處:khans 5th p205
