Abstract:
Over the last few years, there has been a growing interest in digital processing of coronary angiograms to derive precise quantitative measurements on the severity of coronary stenoses. A reliable computer assisted, fully automated edge-detection technique has been developed to assess absolute coronary arterial dimensions from 35 mm cineangiograms. A region of interest to be analyzed is optically magnified and video-digitized prior to the automated contour detection. Contour positions are corrected for pin-cushion distortion.
