| 内容記述 | At Heavy Ion Medical Accelerator in Chiba (HIMAC), more than 200 ocular melanoma patients have been successfully treated by carbon-ion beams since 2001. Traditionally, the vertical and horizontal port with the passive beam delivery system were used to irradiate target volume. To evaluate the advantage of use of rotating gantry and energy scanning carbon-ion beams for choroidal malignant melanoma, we have started the commissioning of the treatment from 2017. The treatment techniques are mostly the same as generally used in HIMAC except for the suturing titanium clips to the outer sclera surface for target positioning. To make the effective dose calculation possible using treatment planning system (TPS), computed tomography (CT)-based treatment planning is employed. By evaluation of the dose distribution, energy scanning with rotating gantry showed to be equal to superior compared to traditional passive scattering method. Evaluation of dose calculation and beam delivery accuracy have proven that the ocular melanoma treatment with rotating gantry and energy scanning carbon-ion beam was feasible. | |||||
