What is Respiratory Gating System?
Respiratory Gating System is essential to the imaging diagnoses and the radiation therapy. In the imaging diagnoses, the respiration-gated image provides the blur-corrected image, and in the radiation treatment it minimizes the area of the treatment target tumor which moves due to patient respiration.
At AAPM Report No. 92 written by AAPM Task Group 76 in July 2006, it is reported that the first study of the respiration-gated radiation therapy was conducted in Japan. The study was conducted at University of Tsukuba Hospital. In 1989 ANZAI, in collaboration with University of Tsukuba Hospital, developed the Respiratory Gating System for the first time in the world. The AZ-733V, a world-standard model of the Respiratory Gating System, utilizes “ANZAI BELT” as the respiratory sensor which has been used from the original model. Now, we would like to introduce the new model, AZ-733VI, with the additional safety function and the new type of respiratory sensor “Laser Sensor“.
