Document Type and Number:
Japanese Patent JP6371515
Kind Code:
B2
Abstract:
An X-ray image processing apparatus includes a first difference processing unit for generating a first difference image by performing difference processing between a mask image obtained by capturing an object before an inflow of a contrast medium and a live image after the inflow of the contrast medium, a first obtaining processing unit for obtaining a line-shaped region indicating a region, into which the contrast medium has flowed, using a distribution of pixel values in the first difference image, a second obtaining processing unit for obtaining a peripheral region of the line-shaped region from the first difference image using pixel values of pixels adjacent to the line-shaped region, and a registration processing unit for performing registration between pixels of the live image and the mask image by comparing positions using the line-shaped region and the peripheral region.
