An X-ray diagnostic apparatus of an embodiment includes processing circuitry. The processing circuitry determines a concentration of a contrast agent in contrast-enhanced image collection based on first reference information in which a recommended contrast in a contrast-enhanced image is associated with each region of interest to be subject to collection of the contrast-enhanced image, and on second reference information that indicates a relation among a generation condition of an X-ray, a concentration of a contrast agent, and a contrast. The processing circuitry calculates setting information of an injector to inject a contrast agent to the subject based on the determined concentration of a contrast agent.

X-ray diagnostic apparatus and medical-information processing apparatus

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.

Medical image processing apparatus, X-ray diagnostic apparatus, and computer-implemented method

A storage unit stores volume data including a blood vessel region. An extracting unit extracts the blood vessel region from the volume data. A specifying unit specifies a position of a region of interest in the blood vessel region and a deflection direction of a blood vessel region included in the region of interest. A determining unit determines a viewing position and a viewing direction based on the position of the region of interest and the deflection direction. A generating unit generates image data concerning the viewing position and the viewing direction based on the volume data. A display unit displays an image represented by the image data.

Image processing apparatus and image processing method

In an embodiment, an X-ray diagnostic apparatus includes an image capturing unit which captures an X-ray image of a subject on a tabletop, a movement mechanism which moves the tabletop and the image capturing unit relative to each other, an acquisition unit which acquires device position information on the tabletop and the image capturing unit in capturing the X-ray image, a display unit which displays the X-ray image captured by the image capturing unit, an input unit which inputs added information to be added to the X-ray image displayed on the display unit, and a management unit which manages the X-ray image captured by the image capturing unit, the device position information acquired by the acquisition unit, and the added information inputted by the input unit in association with one another.

X-ray diagnostic apparatus

An X-ray image diagnosis apparatus according to an embodiment includes: an image processing unit configured to create a synthesized image by synthesizing an X-ray image of a region of interest inside a given region and an X-ray image of a peripheral region excluding the region of interest in the given region, wherein when the region of interest is changed, the image processing unit acquires an X-ray image of a changed region which is in the region of interest before the change and is changed to the peripheral region, from the X-ray image of the region of interest before the change, and then superimposes the X-ray image of the changed region on the X-ray image of the peripheral region to create the synthesized image.

X-ray image diagnosis apparatus

According to one embodiment, an X-ray diagnostic apparatus includes processing circuitry. The processing circuitry generates a plurality of contrast images sequentially based on X-rays after administration of a contrast medium to the object, determines a monitoring region in the plurality of contrast images, monitors change in signal strength of each of pixels included in the monitoring region, and determines whether or not the signal strength of each of the pixels included in the monitoring region satisfies a specified condition. The processing circuitry controls an X-ray generator based on a result of the determination so as to reduce an X-ray dose or turn off irradiation. The processing circuitry generates a parametric image based on a feature amount determined by change in signal strength of each of pixels of a part of the plurality of contrast images sequentially generated before the X-ray generator is controlled based on the result of the determination.
