System for Frame Selection for Optimal Registration of a Multi-frame Dataset

摘要

A system and method 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, determination of a score value for each image of said sequence of X-ray images, selection of a set of images from said sequence of X-ray images based on the determined score values, the set of images excluding one or more images of said sequence of X-ray images, and generation of an averaged image from said set of images.

主权项

1. An X-ray imaging system providing enhanced image feature visualization, comprising:
at least one repository of 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; and an image data processor for, determining, for each image of said sequence of X-ray images, a score value based on a maximum value of the portion of said signal data associated with the image, a minimum value of the portion of said signal data associated with the image, and a composite value of the signal data representing electrical activity of the heart of the patient over the time interval; selecting a set of images from said sequence of X-ray images based on the determined score values, the set of images excluding one or more images of said sequence of X-ray images; and generating an averaged image from said set of images.
