kVue™ CT Overlays provide a method of accounting for the dosimetric properties of the kVue™ Couch Tops by enabling CT imaging of the treatment specific kVue™ insert and immobilization accessories to seamlessly support the simulation and treatment planning process. This is due to the fact that the kVue™ CT Overlays and kVue™ Couch Tops use inserts that have the same dosimetric properties. The kVue™ platform is designed to adhere to the guidelines set forth in AAPM TG176 and therefore increases the potential for more accurate dose planning and delivery.
