Gammex CT Sim Laser systems are used in the simulation stage of radiation therapy to prepare a patient for treatment. The lasers can be moved to a point that defines the radiation treatment isocenter or can be used to define the center of the CT imager. The Gammex CT Sim is intended to read laser positioning coordinates in a specified file format. Typically the coordinates are calculated by a Radiation Therapy Treatment Planning System (RTPS) or CT Virtual Simulation System.
A fixed or variable focal distance lasing device assembly designed to project a harmless beam (light pattern) onto a patient's skin or other alignment device. It is typically used to position and/or monitor the position of a patient during diagnostic imaging, radiation therapy, or radiation therapy treatment planning or simulation procedures. A set of these assemblies is used to enable precise and reproducible 1, 2, or multi-dimensional alignment of a selected portion(s) of the patient's anatomy with respect to a radiation beam(s) used during diagnostic or therapeutic procedures. It typically includes a light source, mechanical/electronic controls, and associated mounting devices.
