摘要： A charged particle beam reduces treatment time in the uniform scanning or in the conformal layer stacking irradiation. In the uniform scanning, an optimum charged particle beam scan path for uniformly irradiating a collimator aperture area is calculated. In the conformal layer stacking irradiation, an optimum charged particle beam scan path for uniformly irradiating a multi-leaf collimator aperture area of each layer for each of the layers obtained by partitioning the target volume is calculated. Alternatively, a minimum irradiation field size that covers the multi-leaf collimator aperture area of each layer is calculated, and a scan path corresponding to the irradiation field size, prestored in a memory of a particle therapy control apparatus, is selected. The charged particle beam scan path is optimally changed in the lateral directions in conformity with the collimator aperture area in the uniform scanning or in each layer in the conformal layer stacking irradiation.

摘要： In a particle therapy treatment planning system for creating treatment plan data, the movement of a target (patient's affected area) is extracted from plural tomography images of the target, and the direction of scanning is determined by projecting the extracted movement on a scanning plane scanned by scanning magnets. Irradiation positions are arranged on straight lines parallel with the scanning direction making it possible to calculate a scanning path for causing scanning to be made mainly along the direction of movement of the target. The treatment planning system can thereby realize dose distribution with improved uniformity.

摘要： A method for adjusting an aberration is disclosed that adjusts the aberration existing in a light spot by using a control signal generated from a wobbling signal and a reproduction signal, and thereby maintaining an appropriate S/N ratio for both the wobbling signal and the reproduction signal even when astigmatism, spherical aberration, or other aberrations are present. In an optical pickup, by moving a collimator lens along a light path, a spherical aberration is generated on the light emitted from a light source, a reproduction signal (RF signal) is obtained from the light reflected from an optical disk, a wobbling signal is obtained from the light reflected from grooves on the optical disk, and the correction aberration is adjusted based on the RF signal and the wobbling signal.
