| In a particle therapy facility, accelerated particles are transported to treatment room, then delivered towards a tumor by a gantry system to acquire multiple treatment angles, so that multiple treatment angles can be used to minimize the dose in healthy tissue in vicinity of the tumor. To realize the rapid change of treatment angle, enabling stereotactic irradiations to mitigate motion effect on the dose distribution, we are designing a HTS (High Temperature Superconducting) Spectroscopy-type Gantry System. In the conception of spectroscopy-type gantry, the beam is guided to the appropriate azimuthal angle with cylindrical magnetic field surrounding the patient, and treatment angles are set only by adjusting the strength of dedicated magnets, instead of rotating a gantry with magnets of the beam transport around the patient. This method is realizing a fast change of azimuthal angle in a static gantry system. The rapid change of treatment angle also gives potential possibility of FLASH therapy. In this work, a conceptual design of a HTS Spectroscopy-type Gantry System and different methods to optimize its beam transportation to the patient will be discussed. |
