Abstract

Beating of the heart is a type of motion which is the most difficult to control during the cardiac CT scan and causes significant artifacts. Hearts have the least motion at systole and diastole phase which for an average heart happens at 45% and 75% phase respectively. However, in practice this is not guaranteed, so doctors sometimes reconstruct several phases, review all those images and then make diagnosis from the phase that has the least artifacts. The new method for automatic dynamic optimal phase reconstruction has image quality comparable to the manual phase selection but it also significantly reduces the exam time by omitting the review of unnecessary phases.
