  • Publication number: 20180028138
    Abstract: A medical image processing apparatus includes a processor configured to acquire a first image and a second image captured by radiating an X ray to an object, generate a synthesis image by overlapping a first region of the first image with a second region of the second image, and determine matching accuracy representing a degree to which the first region and the second region match with each other; and a display configured to display the matching accuracy and the synthesis image. The medical image processing apparatus captures and synthesizes a plurality of images and display information of matching accuracy of the plurality of images. The medical image processing apparatus may provide a more accurate image by correcting a mismatched region of an overlapped region between the images.
