Title:
IMAGE PROCESSING DEVICE, MAGNETIC RESONANCE IMAGING DEVICE, AND IMAGE PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/132830
Kind Code:
A1
Abstract:
In the present invention, in order to reduce errors in assessment of a structure due to noise, and to remove noised superimposed on an image while retaining significant information and without introducing artificiality into a resultant image after noise removal, a reference image created from a plurality of source images and each source image are compared to compute a degree of similarity, and the degree of similarity is used as an index for noise determination. The source images are smoothed and synthesized using the index, and a final image is obtained from which noise has been removed.
