IMAGE PROCESSING APPARATUS, X-RAY IMAGE DIAGNOSIS APPARATUS AND IMAGE PROCESSING METHOD

摘要

Displaying digital X-ray image data with a constant image quality is achieved by performing noise reduction without dependence on the S/N characteristic and further without causing the edge portions of image signals to be blurred. For this purpose, a medical image is raster-scanned and read (S301); a similarity threshold value (P) for which the S/N characteristic has been taken into account is used to determine whether the component is of an image signal or of noise for each of a plurality of pixels of interest (S302-S304); and either a process (S305) following a determination that the component is of an image signal or a process (S306) following a determination that the component is of noise is performed for each pixel of interest.
