Current Techniques in Three-Dimensional CT Simulation and Radiation Treatment Planning

November 01, 1995

The modern CT simulator is capable of interactive three-dimensional (3D) volumetric treatment planning; this allows radiation oncology departments to operate without conventional x-ray simulators. Treatment planning is performed at the time of virtual simulation by contouring the organs or volumes of interest and determining the isocenter.
