摘要： The particle therapy system includes a particle beam generator for generating a particle beam; an irradiation nozzle arranged in a treatment room and irradiating a target with the particle beam; a particle beam transport system communicating the particle beam generator with the irradiation nozzle; an X-ray imaging device arranged in the treatment room and imaging the position of the target through irradiation with X-rays; a dosimeter arranged at a position passed by the particle beam in the irradiation nozzle; and a control apparatus performing control to exclude the measurement result of the X-rays from the measurement result obtained using the dosimeter when the X-rays are emitted during treatment.

摘要： A scanning magnet of an irradiation nozzle is controlled to irradiate the ion beam irradiated from a synchrotron accelerator to a target position Pi,j of a spoti,j in a certain layer Li of a target volume, using a scanning control apparatus. A deviation Dj between the target position Pi,j and an actual irradiation position Pai,j is obtained. Using the deviation Dj, a systematic error Esi,j and a random error Eri,j of the actual irradiation position Pai,j are obtained. Whether the systematic error Esi,j exists within a first permissible range of the systematic error Esi,j is determined. Whether the random error Eri,j exists within a second permissible range of the random error Eri,j is determined. When the systematic error Esi,j or the random error Eri,j is deviated from the permissible range, the irradiation of the ion beam to the target volume is stopped.

摘要： The present invention provides a particle therapy system including an irradiation compensating device made up of an energy absorber, a first collimator, and a second collimator for use in a short-range region. The irradiation compensating device is characterized by a mechanism for attaching and detaching the first energy absorber, first collimator, and second collimator. The first collimator is located upstream where the beam diameter is small with a view to suppressing the width of the compensating device, thereby contributing to making the compensating device small and lightweight. The second collimator is located downstream to improve penumbrae.

摘要： The charged particle beam irradiation system includes a charged particle beam generating unit, scanning electromagnets, a beam irradiation apparatus, beam radiation dose measuring instrument(s), and a beam position measuring instrument for obtaining one or both of the position and the width of the beam scanned by the scanning electromagnets. The beam position measuring instrument obtains one or both of the position and the width of the beam for each irradiation spot and determines whether the obtained result is within an allowable range and obtains one or both of the position and the width of the charged particle beam for each split during irradiation to the spot with the charged particle beam regarding a split of which a dose is managed by dividing a part of or all of irradiation spots into irradiation sections and determines whether the obtained result is within an allowable range.
