MEDICAL VIEWING SYSTEM AND METHOD FOR ENHANCING STRUCTURES IN NOISY IMAGES

摘要

A viewing system and method for enhancing objects of interest represented on a moving background in a sequence of noisy images and for displaying the sequence of enhanced images, comprising extracting means ( 11 ) for extracting features related to an object of interest in images of the sequence; registering means ( 12 ) for registering the features related to the object of interest with respect to the image referential, yielding registered images ( 13 ); similarity detection means for determining the resemblance of the representations of a registered object of interest in succeeding images and weighing means for modulating the intensities of the pixels of said object of interest over the images of the sequence; temporal integrating means ( 14, 33 b) for integrating the object of interest and the background over a number, or at least two, registered images ( 13 ) of the sequence; and display means ( 54 ) for displaying the processed images ( 15, 45 ) of the enhanced registered object of interest on faded background. Application: Medical Imaging. X-ray Fluoroscopic Imaging.
