Abstract: In one embodiment, an X-ray diagnostic apparatus includes a memory and processing circuitry. The processing circuitry causes the memory to store a movement path that is defined by a combination of movements of a plurality of movable shafts of an imaging apparatus and is generated based on movements of the imaging apparatus in response to a user's operation. The processing circuitry moves the imaging apparatus in a reverse order of the movement path stored in the memory.

Abstract: According to one embodiment, an X-ray diagnostic apparatus includes processing circuitry. The processing circuitry sets a plurality of ROIs in a first X-ray image. The processing circuitry calculates a statistical value for each ROI based on a plurality of values of pixels included in each ROI, thereby obtaining a plurality of statistical values. The processing circuitry acquires a threshold value for each statistical value. The processing circuitry determines a set of X-ray conditions relating to capturing of a second X-ray image subsequent to the first X-ray image based on the statistical value and the threshold value relating to each ROI.

Abstract: An X-ray diagnosis apparatus according to an embodiment includes an X-ray limiter having four diaphragm blades; and a console on which four physical operating units that correspond to the four diaphragm blades are placed at four positions. When viewed from the side of the operator of the console, the four operating units are placed on the far side, the near side, the left side, and the right side. The far-side operating unit, the near-side operating unit, the left-side operating unit, and the right-side operating unit correspond to the upper diaphragm blade, the lower diaphragm blade, the left-side diaphragm blade, and the right-side diaphragm blade, respectively, with reference to an X-ray image displayed in a display. An operation of moving the far-side operating unit in the far-side direction results in the movement of the upper diaphragm blade in the upward direction of the X-ray image displayed in the display, and an operation of moving the far-side operating unit in the near-side direction results in the movement of the upper diaphragm blade in the downward direction of the X-ray image displayed in the display. An operation of moving the near-side operating unit in the far-side direction results in the movement of the lower diaphragm blade in the upward direction of the X-ray image displayed in the display, and an operation of moving the near-side operating unit in the near-side direction results in the movement of the lower diaphragm blade in the downward direction of the X-ray image displayed in the display. An operation of moving the left-side operating unit in the leftward direction results in the movement of the left-side diaphragm blade in the leftward direction of the X-ray image displayed in the display, and an operation of moving the left-side operating unit in the rightward direction results in the movement of the left-side diaphragm blade in the rightward direction of the X-ray image displayed in the display. An operation of moving the right-side operating unit in the leftward direction results in the movement of the right-side diaphragm blade in the leftward direction of the X-ray image displayed in the display, and an operation of moving the right-side operating unit in the rightward direction results in the movement of the right-side diaphragm blade in the rightward direction of the X-ray image displayed in the display.

Abstract: An operation device comprises a detector configured to detect an operation on a virtual switch by an operator to operate an X-ray irradiation in an X-ray diagnosis apparatus, wherein the virtual switch is virtually set at a position settled relatively with respect to the operator and output circuitry configured to output a detection result of the operation detected by the detector to the X-ray diagnosis apparatus to be operated. This device eliminates the need for looking away from a display monitor every time the operator operates the X-ray diagnosis apparatus.

Abstract: An X-ray diagnostic device according to embodiments includes an X-ray tube, an X-ray detector, a couchtop, a drive mechanism, an input interface, and processing circuitry. The X-ray tube emits X-rays to a subject. The X-ray detector detects X-rays transmitted through the subject. The couchtop has the subject placed thereon. The drive mechanism generates the driving force for moving the couchtop. The input interface accepts instruction operations from an operator regarding the movement of the couchtop. The processing circuitry acquires one of a weight applied to the couchtop and a deflection amount of the couchtop, and determines the driving force to be generated by the drive mechanism based on one of the weight and the deflection amount and on the instruction operation.
