A medical device can perform treatment and diagnosis without causing a sense of unease to the patient. The medical device includes a substantially ring-shaped support frame provided in such a manner that a central axis through which an isocenter passes is disposed substantially horizontally; a substantially ring-shaped moving gantry which slides relative to the support frame and which has an opening at the isocenter side thereof a radiation emitter configured to emit a beam towards the isocenter; and a protective cover which covers the radiation emitter and an inner circumferential side of the moving gantry and which moves together with the moving gantry.

A radiotherapy system includes: a waveguide, an adjustable waveguide, and a non-reciprocal circuit element. The waveguide transmits a high-frequency wave from a high-frequency power source to an acceleration tube. The adjustable waveguide is included in said waveguide and transforms a part of said waveguide. The non-reciprocal circuit element is provided between said acceleration tube and said adjustable waveguide in said waveguide. Said acceleration tube accelerates charged particles for generating therapeutic radiation by using said high-frequency wave.
摘要:
In an acceleration tube conditioning apparatus for performing a conditioning process on an acceleration tube when a high frequency power signal to be supplied to an acceleration tube is generated by a high frequency power supply, a power value collecting section collects a traveling wave power value and a reflection wave power value from a sensor which monitors the traveling wave power signal and the reflection wave power signal. A high frequency calculating section calculates a resonance frequency of the acceleration tube based on the traveling wave power value and the reflection wave power value. A high frequency adjusting section determines a high frequency value based on one of the traveling wave power value and the reflection wave power value as a selection power value, and a high frequency power supply control unit controls the high frequency power supply based on the high frequency value. The high frequency value indicates a constant value when the selection power value is smaller than a predetermined value, and indicates the calculated resonance frequency when the selection power value is larger than the predetermined value.

A radiotherapy device control apparatus controlling a radiotherapy device, includes an affected area position database, a motion collection section, and an irradiation position control section. The radiotherapy device includes a therapeutic radiation irradiation device radiating therapeutic radiation, a motion detector detecting motion of the subject, and a drive device moving the therapeutic radiation irradiation device with respect to the subject. The affected area position database associates a position set with a motion related information set related to the motion. The motion collection section collects the motion from the motion detector. The irradiation position control section moves the therapeutic radiation irradiation device by the drive device such that the therapeutic radiation is radiated to a position in the position set corresponding to motion related information of the motion.

A radiotherapy device control apparatus controls a radiotherapy device. The control apparatus includes a reference image creation section, a transmitted image creation section and an affected area position control section. The radiotherapy device includes a therapeutic radiation irradiation device that radiates therapeutic radiation, an imager that generates an image of a subject by using radiation transmitted through the subject, and a drive device that moves a couch, where the subject is arranged, with respect to the therapeutic radiation irradiation device. The affected area position control section judges whether a relative position of the couch with respect to the therapeutic radiation irradiation device is appropriate and changes the relative position of the couch by using the drive device based on a first position and a second position.
