Method for determining ECG-triggered recording times for imaging to support interventional and diagnostic cardiac procedures

摘要

The invention is directed to a method for determining a plurality of ECG-triggered recording times for cardiac imaging, comprising the steps: recording a plurality of images of the heart at predetermined time intervals; assigning the images to specific cardiac phase times; comparing the images in order to determine similarity measures between two images in each case, said similarity measures representing states of the heart requiring to be imaged that are similar in terms of imaging technology; identifying a group of images with mutual similarity measures in a predefined area, between the pairs of images; and specifying the cardiac phase times associated with the images in the group as the plurality of ECG-triggered recording times. In a further aspect the method can additionally include the step of performing the moving-target imaging based on image recordings at the specific recording times with the aid of ECG triggering.
