Abstract
In order to reduce errors in assessment of a structure caused by noise and remove the noise superimposed in an image without causing artificiality in the result image after the removal while retaining significant information, a similarity is calculated by comparing a reference image generated from a plurality of original images with each original image and set as an index of noise determination. The respective original images are smoothed and synthesized using the said index to acquire a final image after the noise removal.
