The respiratory gating radiotherapy technique can apply to moving tumors, such lung and liver cancer. CGMH introduces Real-time Position ManagementTM (RPM) respiratory gating system, which gates the beam delivery during treatment to account for organ motion. The infrared camera tracks tumors that move during treatment as the patient breathes in and out, then the linac accelerator controlled x-ray beam treats the tumor within the gated phase to assure the accuracy of treatment position. The non-invasive infrared tracking marker box is placed on patient's body. We have the big bore CT simulator with four-dimensional CT capability, it can record combines continuous monitor chest wall movement during treatment with pre-plotted target trajectories to ensure the maximum dose is delivered to the target while avoiding critical organs. In this case, we can treat patients with high accuracy while minimize treatment errors. Radiation beam is gated to when the target falls within the treatment field, patient can breathe normally and remain comfortable and high compliance during the treatment. This technique will takes about five to ten minutes more than the regular treatment time.
