Description
The Shanghai Proton Therapy Device (SAPT) is the first domestic proton therapy system, and China has a truly self-developed and marketable domestic high-end proton therapy device. The gantry is an important part of the proton therapy device, which has the characteristics of large inertia, large size, and large weight, and at the same time requires high motion positioning accuracy and reliability. In this talk, I will discuss the 360° gantry and superconducting gantry structures, and introduce some studies on the accuracy of the center of peer. Through software simulation, we studied the displacement of the equicenter point during the rotation of the gantry, and made some creative improvements to the structure, so that the displacement we were concerned about was controlled below 0.5mm, and the simulation results were regularly analyzed. Our results reveal the changes and influencing factors of the central point such as the rotation process of the gantry, and pave the way for the application of superconductivity technology in the gantry.
