Abstract: According to one embodiment, an X-ray diagnosis apparatus includes an X-ray generator, an X-ray diaphragm, an X-ray detector, an image capturing unit, a blood vessel running information acquiring unit, a device position specifying unit, and a diaphragm controller. The X-ray generator emits X-rays. The X-ray diaphragm restricts a region to be irradiated with X-rays emitted from the X-ray generator. The X-ray detector detects X-rays emitted from the X-ray generator. The image capturing unit acquires an X-ray image based on a detection result obtained by the X-ray detector. The blood vessel running information acquiring unit acquires blood vessel running information. The device position specifying unit specifies the position of a device in the X-ray image. The diaphragm controller controls the X-ray diaphragm based on the blood vessel running information and the position of the device.

Abstract: According to an X-ray diagnostic apparatus, an X-ray tube radiates X-rays. An X-ray collimator adjusts an irradiation region of the X-rays. An X-ray detector includes a first detector and a second detector having a smaller detection area than a detection area of the first detector. The X-ray detector is able to detect the X-rays radiated with the first detector and the second detector at the same time. Processing circuitry generates a synthesized image obtained by synthesizing a first X-ray image generated based on an output from the first detector that detected the X-rays radiated in the irradiation region adjusted, and a second X-ray image generated based on an output from the second detector that detected the X-rays radiated in the irradiation region adjusted, the synthesized image having an image size corresponding to an aspect ratio of the irradiation region. The processing circuitry causes a display to display the synthesized image.

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 apparatus of an embodiment includes an input interface, and processing circuitry. The input interface accepts an input operation performed by an operator. The processing circuitry identifies a period in which periodic movement is small in an X-ray irradiation area. The processing circuitry determines irradiation start timing of an X-ray according to the period. The processing circuitry controls to perform X-ray irradiation of a relatively high dose in the determined irradiation start timing on condition that the input operation is being continued.

Abstract: According to one embodiment, a medical image processing apparatus includes processing circuitry. The processing circuitry specifies, before position alignment between a first X-ray image and a second X-ray image which is acquired with a device inserted, a device area candidate in the second X-ray image as a candidate of an area where the device appears. The processing circuitry performs the position alignment using first processing of removing the specified device area candidate or second processing of reducing a contribution of the specified device area candidate.

Abstract: A medical information processing apparatus according to an embodiment includes processing circuitry. The processing circuitry is configured to obtain an image capturing a space in which a manipulation is being performed on an examined subject and non-image information related to at least one of the manipulation, the examined subject, or the space. Also, the processing circuitry is configured to detect a situation having a high possibility for an occurrence of an abnormality in the space, on the basis of the obtained image, the obtained non-image information, and first correspondence information. The first correspondence information indicates a correspondence relationship between two or more images capturing the space, non-image information, and abnormalities having a high possibility of occurring in the space.
