A medical image-processing apparatus of an embodiment includes a processing circuitry. The processing circuitry acquires a plurality of medical images including a predetermined region and having different time phases. The processing circuitry sets a first region of interest and a second region of interest in each of the plurality of medical images. The processing circuitry derives a temporal change in first pixel values, which are pixel values on the first region of interest, on the basis of the first pixel values and derives a temporal change in second pixel values, which are pixel values on the second region of interest, on the basis of the second pixel values. The processing circuitry sets a first time window on the basis of the temporal change in the first pixel values and sets a second time window on the basis of the temporal change in the second pixel values.

Medical image-processing apparatus, medical image-processing method, and storage medium

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.
