Radiotherapy Simulation Systems, Computed Tomography-Based
Definition : Radiotherapy simulation systems that use a computed tomography (CT) scanner with specialized hardware and software for radiotherapy simulation and treatment-field delineation. These systems can delineate the tumor in CT slices, determine the target volume using a treatment-planning computer, select the treatment field, and mark the patient for radiation treatment in a single session. CT-based systems are also used for verification of tumor margins, tracking of tumor regression, and three-dimensional image analysis for multileaf collimators and conformal radiotherapy.
