IMAGE PROCESSING METHOD, PROGRAM, AND IMAGE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/181726
Kind Code:
A1
Abstract:
This image processing method includes: a step in which a vascular mask creating unit creates a vascular mask image by subjecting an image, obtained from a magnetic resonance signal obtained by enhancing regions corresponding to blood vessels in an MRI image, to removal of dot-shaped low signals, removal of linear low signals, extraction of linear low signals, removal of dot-shaped high signals, removal of linear high signals, and extraction of linear high signals; and a step in which a mask processing unit generates an image obtained by employing the vascular mask image to remove a vascular structure from a phase difference enhanced image created from the MRI image.
