Abstract: An image processing apparatus according to an embodiment includes processing circuitry. The processing circuitry extracts a fixed object included in chronologically collected X-ray images and having a substantially fixed position. The processing circuitry detects a target object included in each of the X-ray images, on the basis of extraction results of the fixed object. The processing circuitry generates a plurality of corrected images by a correction process to substantially match, with a reference position, the detected position of the target object in an X-ray image other than a reference X-ray image, the reference position being the detected position of the target object in the reference X-ray image.

Abstract: A medical image-processing apparatus according to an embodiment includes processing circuitry configured to determine a position of a feature point of a device in a first X-ray image, and generate a superimposed image in which a 3D model expressing the device is superimposed on the first X-ray image or a second X-ray image that is acquired later than the first X-ray image. The processing circuitry is configured to superimpose the 3D model on the first X-ray image or the second X-ray image at a position based on the position of the feature point.

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.
