According to one embodiment, an X-ray diagnosis apparatus includes an X-ray tube, an input interface, a holding mechanism, an X-ray detector, a display, and processing circuitry. The X-ray tube is configured to radiate X-rays. The input interface is configured to receive an input manual operation of designating at least a direction. The holding mechanism is configured to hold the X-ray tube, and to move the X-ray tube in accordance with the input manual operation, the X-ray tube radiating X-rays during the moving. The X-ray detector is configured to detect X-rays radiated from the X-ray tube and passing through an object, the X-ray detector generating X-ray image data based on the detected X-rays. The display is configured to subsequently display an X-ray image based on the X-ray image data.

X-ray procedure tables with improved structural strength that enable radiation shielding and integrated medical device and monitoring systems. The design allows the incorporation of an integrated patient support structure, radiation shielding and associated devices and conduits for medical care in procedures that employ X-ray imaging.

A method is for positioning a positionable table for a patient inside a medical imaging device. In an embodiment, the method includes a determination of a table position as a function of an organ or body part of the patient for examination; an ascertainment of correction data for correcting the table position; a determination of a corrected table position based on the ascertained correction data; and a positioning of the table at the corrected table position.

In an X-ray diagnostic apparatus of one embodiment, an image data generator sequentially generates X-ray images based on X-rays transmitted through a subject. An image processor executes: first processing where, in response to an instruction to start correction processing, a position of a target contained in a predetermined X-ray image is obtained as a reference position; and second processing where corrected images in which positions of the target are set at the reference position are sequentially generated from newly generated X-ray images. An image data storage unit stores therein information on a reference position with respect to each set of conditions of manipulation on the subject. Upon receiving the instruction to start correction processing, the image processor executes the second processing by using information on the reference position stored in the image data storage unit, in accordance with a set of the conditions of manipulation on the subject.

An X-ray CT device according to an embodiment includes a gantry, a top board, and a movement mechanism. The gantry includes an X-ray tube that generates X-rays and a detector that detects the X-rays. The top board inserts the subject into the opening section of the gantry. The movement mechanism moves the top board in a longitudinal direction. Furthermore, the position of the top board in a vertical direction at the position that intersects with the path of the X-rays is changed at substantially the same slope relative to the movement distance of the top board when the top board is moved in the longitudinal direction.

According to an embodiment, an X-ray CT system includes a gantry, a first couch, a second couch, a carrier unit, and control circuitry. The gantry includes an X-ray tube, an X-ray detector, and an operation unit. The first couch is arranged in a first room. The second couch is arranged in a second room. When carrying the gantry to the first room, the carrier unit arranges the gantry in an orientation in which the front side of the gantry faces the first couch. When carrying the gantry to the second room, the carrier unit arranges the gantry in an orientation in which the back side of the gantry faces the second couch. The control circuitry controls the direction of the tilt movement of the gantry in accordance with the room where the gantry is arranged.

A scanning system for three-dimensional imaging comprises a bench, a gantry frame, a light source, a sensor and a control unit. The bench is to support a subject to be scanned. The gantry frame is movably mounted at a lateral side of the bench. The light source is movably mounted on the gantry frame so as to emit a light for a radiographic purpose. The sensor is movably mounted at a side of the bench, by opposing to the subject with respect to the bench, so as to receive the light emitted from the light source. The control unit is electrically coupled with the gantry frame, the light source and the sensor so as thereby to perform motion controls upon the gantry frame, the light source and the sensor.

Realized is a pedal mechanism that does not lock and does not provide an operation feeling unless operated in a determined order. The pedal mechanism has first and second pedals 105 and 106, first and second plates 108 and 109, and a locking bar 115. The radius of the second plate 109 is smaller than that of the first plate 108, and the second plate does not come into contact with the locking bar in a state where a circular-arc region of the first plate supports the locking bar 115. Therefore, the second pedal does not give an operation feeling even when stepped on, and the second plate cannot be locked. In a locked state where the locking bar is located in a cutout region of the first plate, the locking bar contacts the second plate, the second pedal provides an operation feeling, and the second plate can be locked.

A radiation monitoring system includes a patient support apparatus. A radiation sensor assembly is operably coupled to the patient support apparatus. The radiation sensor assembly includes a radiation sensor and a first controller. The radiation sensor senses radiation data corresponding to a radiation dose received by a patient. A management system includes a second controller that stores a patient profile database. The second controller is communicatively coupled with the first controller. The first controller communicates the radiation data to the second controller for storage in the patient profile database to monitor the radiation dose received by the patient.

A positioning apparatus and a positioning method has a control element and function 40 includes a radiograph acquisition element 41 that acquires radiograph data detected by two radiography systems selected from a group consisting of a flat panel detector, a DRR (Digital Reconstructed Radiograph) generation element 42 that generates DRR in two different directions by virtually performing fluoroscopic projection relative to the 3-dimensional CT data obtained through the network 17, a positioning element 43 that positions a CT to the X-ray fluoroscopic radiograph obtained from two radiography systems, and a displacement distance calculation element 44 that calculates a displacement distance of the tabletop 31 based on the gap between radiographs for improved positioning. The positioning element 43 has a multidimensional optimization element 45 and a 1-dimensional optimization element 46 that optimize parameters relative to rotation and translation of the fluoroscopic projection to maximize an evaluation function that evaluates a matching degree between the DRR and the X-ray fluoroscopic radiograph.
