According to one embodiment, an X-ray diagnosis apparatus includes an X-ray tube, a diaphragm mechanism, an X-ray detector, image generating circuitry, a display, a first interface, a second interface, and processing circuitry. The processing circuitry controls the diaphragm mechanism and the X-ray tube according to the operation to the first interface so that the X-rays are radiated to a first radiation range, and controls the diaphragm mechanism and the X-ray tube according to the operation to the second interface so that the X-rays are radiated to a second radiation range. The processing circuitry controls the display so that the first display area displays the X-ray images sequentially generated according to radiation of the X-rays, in parallel with the radiation.

X-ray diagnosis apparatus

An X-ray diagnostic apparatus according to one embodiment comprises an X-ray tube, an X-ray detector, a holding mechanism, position specifying circuitry and control circuitry. The X-ray detector detects the X-ray which has been generated by the X-ray tube and has passed through an object placed on a top of a bed movable in an examination room. The holding mechanism holds the X-ray tube and the X-ray detector, and movable in the examination room. The position specifying circuitry specifies a position of the holding mechanism in the examination room and a position of the bed in the examination room. The control circuitry controls the holding mechanism in order to change a position and angle of the holding mechanism based on the position of the holding mechanism and the position of the bed.

According to one embodiment, an X-ray diagnostic apparatus includes a support frame, an input button, and processing circuitry. The support frame supports an X-ray detector which detects X-rays. The input button provides on at least one of an exterior of the support frame and an exterior of the X-ray detector and inputs an instruction to implement an assigned moving operation pattern of a plurality of moving operation patterns concerning movement of at least one of the support frame, the X-ray detector, and a table top. The processing circuitry assigns the input button with an instruction to implement a moving operation pattern, of the plurality of moving operation patterns, which is selected by an operator.

An X-ray diagnosis apparatus detects X-rays output from an X-ray source and transmitted through a subject, and generates images of the inside of the subject, and comprises a detector, an X-ray intensity distribution data generator, and an entrance dose distribution data generator. The detector detects the intensity of the X-rays output from the X-ray source. The X-ray intensity distribution data generator generates X-ray intensity distribution data showing the X-ray intensity for each of a plurality of subdomains of an X-ray irradiation field from the X-ray source based on the detection outcome by the detector. The entrance dose distribution data generator generates entrance dose distribution data showing the dose of X-rays output from the X-ray source and irradiated onto the subject, based on the X-ray intensity distribution data.

According to one embodiment, a holding apparatus includes an arcuated arm, a first roller, and a second roller. The arcuated arm is provided with a guide groove along the outer surface, has a hollow portion inside, and holds the X-ray generator and X-ray detector while making them squarely face each other. The first roller runs in the hollow portion in contact with the inner wall of the hollow portion on the outer surface side. The second roller runs in the guide groove while being fitted in the guide groove, and holds the arm together with the first roller so as to allow the arm to slide along the arcuated direction.

Holding apparatus and X-ray diagnostic apparatus

An X-ray imaging system that allows X-ray images to be acquired from a desired direction by considering the tilt of a tabletop. The X-ray imaging system includes a support unit that holds an X-ray imaging unit that performs X-ray imaging of a subject. The subject is placed on the tabletop. A memory stores in advance imaging angle information from previous imaging. A tilt detector detects the tilt angle of the tabletop. A calculator calculates a correction angle for correcting the imaging angle information based on the imaging angle information and on the tilt angle. A drive unit moves the support unit to a position based on the imaging angle information and the correction angle.

A medical bed apparatus of an embodiment includes: a tiltable top board on which to place an examinee; a photographic mechanism configured to radiograph the examinee; an operation unit which is provided to a lateral side of the top board, and through which at least one of the top board and the photographic mechanism is operated by an operator; and a horizontally-holding mechanism configured to hold the operation unit horizontally when the top board tilts.

Medical bed apparatus

According to one embodiment, an X-ray diagnostic apparatus includes X-ray generators, X-ray detectors, high voltage generators, a switching device, an abnormality detection unit and a control unit. The high voltage generators are configured to apply voltages to the X-ray generators. The switching device is configured to switch outputs from the high voltage generators to the X-ray generators. The abnormality detection unit is configured to detect an abnormality in the high voltage generators. The control unit is configured to control the switching device to switch from an output from a high voltage generator of which abnormality has been detected by the abnormality detection unit toward a corresponding X-ray generator to an output from another high voltage generator toward the corresponding X-ray generator.
