Abstract
An Angiographic X-ray imaging system provides enhanced image feature visualization. At least one repository includes data representing a sequence of X-ray images of a portion of patient anatomy acquired over a time interval and signal data representing electrical activity of the heart of the patient over the time interval. An image data processor determines for individual images of the sequence of X-ray images, characteristics of a portion of the signal data associated with a corresponding image. The characteristics comprise at least one of, (a) a peak to peak value of a portion of the signal data associated with a corresponding image and (b) an average value of a portion of the signal data associated with the corresponding image. The image data processor selects a set of images exclusive of particular images from the sequence of X-ray images in response to the determined characteristics and generates an averaged image from the set of images.
