摘要:
A malfunction procedure indicating system which monitors continuously the condition of a plurality of inspection items associated with the operation of a vehicle, whereby when the existence of a malfunction in at least one of the plurality of inspection items is detected, a first procedure corresponding to the malfunction is indicated by both verbal representation and visual display during the operation of the vehicle and a second procedure following the first procedure is also indicated by both verbal representation and visual display.

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.

An object is to provide a medical device which can rotate a radiation emitter or the like with high positional precision over an extended period of time. Provided are a support frame installed such that a central axis thereof is positioned substantially horizontally; circular tracks respectively disposed on both side faces of the support frame; a moving gantry configured to revolve relative to the support frame via sliding portions configured to slide on the circular tracks; and revolving driving means for revolving the moving gantry, wherein the moving gantry is constructed of a rigid-framed structure formed of a first side portion and a second side portion disposed so as to flank the support frame from both side faces thereof, and coupling portions for coupling the first side portion and the second side portion.

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 deflection magnetic system and method are provided to deflect an electron beam through a predetermined angle while maintaining a circular cross-section for the electron beam. A plurality of spaced magnetic fields are provided to deflect the electron beam through angles less than the total predetermined angle, but the total angle is achieved when the beam passes through the last magnetic field. Magnetic shields are provided between the spaced magnetic fields to absorb any undesired leakage magnetic flux.

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 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.

A radiotherapy device control apparatus controlling a radiotherapy device, 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 radiating therapeutic radiation, an imager generating an image of a subject by using radiation transmitted through the subject, and a drive device moving a couch, where the subject is arranged, with respect to the therapeutic radiation irradiation device. The reference image creation section collects a reference image taken by the imager. The transmitted image creation section takes a transmitted image of the subject by the imager. The affected area position control section judge whether a relative position of the couch with respect to the therapeutic radiation irradiation device is appropriate based on a position where a characteristic point of the subject is displayed in the transmitted image and a position where the characteristic point is displayed in the reference image. The affected area position control section changes the relative position of the couch by using the drive device based on the first position and the second position.
摘要:
An automobile running position indicator apparatus which comprises a device for generating a unit coverage distance signal each time the automobile has covered a unit distance, a device for generating a direction signal representing the automobile running direction at each time and a device for generating set signals representing the distance and direction from the starting point to the destination. A vectorical length from the starting point to the destination is operated from the set signals. The distance covered by the automobile is accumulated for each direction from the distance signal and the direction signal thereby to calculate a vectorial value length from the starting point to the present position. These vectorial values are used to determine a vectorial length from the present position to the destination, and the resulting vectorial direction and distance are displayed in the same display section.
