Abstract: A medical image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry obtains X-ray images that are sequentially collected during a partial period of time in a cardiac phase of a subject who has a device inserted into the body. Then, the processing circuitry identifies a characteristic region of the device captured in a plurality of obtained X-ray images, and performs registration in which the position of the characteristic region identified in a reference image, which is one of the plurality of X-ray images, serves as the reference position, and in which the position of the characteristic region identified in the plurality of X-ray images collected after the reference image is adjusted based on the reference position.

Abstract: A marker-coordinate detecting unit detects coordinates of a stent marker on a new image when the new image is stored in an image-data storage unit; and then a correction-image creating unit creates a correction image from the new image through, for example, image transformation processing, so as to match up the detected coordinates with reference coordinates that are coordinates of the stent marker already detected by the marker-coordinate detecting unit in a first frame. An image post-processing unit then creates an image for display by performing post-processing on the correction image created by the correction-image creating unit, the post-processing including high-frequency noise reduction filtering-processing, low-frequency component removal filtering-processing, and logarithmic-image creating processing; and then a system control unit performs control of displaying a moving image of an enlarged image of a set region that is set in the image for display, together with an original image.

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.

Abstract: A medical information processing apparatus of an embodiment includes an image acquiring unit, an event acquiring unit, a managing unit, and an output unit. The image acquiring unit sequentially acquires medical images during a treatment procedure for a subject. The event acquiring unit sequentially acquires events in the treatment procedure on the basis of the medical images during the treatment procedure. The managing unit manages the medical images and the events, in association with temporal information on the treatment procedure. The output unit outputs the medical images such that relations between the medical images and the events are able to be known.

Abstract: In one embodiment, an X-ray diagnostic apparatus includes an X-ray source, an X-ray detector, an arm, and processing circuitry. The arm supports the X-ray source and the X-ray detector. The processing circuitry identifies a three-dimensional running direction of a blood vessel of an object from a plurality of images that are obtained by using the X-ray source and the X-ray detector to image the object from at least two different angles, and controls positions of the X-ray source and the X-ray detector by using the arm in such a manner that a target position of the blood vessel is imaged from the at least two different directions determined depending on the three-dimensional running direction.
