It’s a C-T scan to stabalize the patient for treatment planning without having the patient move from one room to anohter. Another treatment, the Belo System, focuses on lung cancer. Straped to a patients chest it detects the breathing cycle and pressure changes. Then there’s the Optical Guidance System; an equipped camera that tracks the movement of the patients chest and records the motion of the tumor when the person breathes. The Optical Guidance tool is also used for precise detection of brain and neck cancer. It’s non invasive and uses a mouth piece to hold a camera in position while the patient wears a special head mask helping the person to keep still during the procedure.
