Abstract
Target respiration information is created in which a patient respiration pattern is set in advance to a cycle suitable for an operation cycle of a synchrotron, and the target respiration information is informed to the patient, so that a patient respiration timing becomes a state suitable for an operation of the synchrotron in such a manner that the patient consciously matches with the informed information.
Claims10
A respiration navigation apparatus used for a particle beam treatment apparatus including an accelerator operated on the basis of predetermined operation timing information, the respiration navigation apparatus comprising:
- a respiration navigation computer which stores target respiration information having a cycle set in advance on the basis of the operation timing information, and
- a respiration information informing device which informs a patient of distinct past and future portions of a respiration waveform obtained by quantifying information, involved with a respiration amplitude of the target respiration information, in time series.
A particle beam treatment apparatus comprising:
- a particle beam generating device which includes an accelerator operated on the basis of predetermined operation timing information and generates a particle beam;
- a patient respiration measurement device which measures a patient respiration state;
- a respiration synchronizing device which allows a patient to be irradiated with the particle beam on the basis of the patient respiration state information measured by the patient respiration measurement device;
- a respiration navigation computer which stores target respiration information having a cycle set in advance on the basis of the operation timing information;
- and
- a respiration information informing device which informs the patient of distinct past and future portions of a respiration waveform obtained by quantifying information, involved with a respiration amplitude of the target respiration information, in time series.
