Automatic Detection of Left and Right Ventricles from CTA Enables Efficient Alignment of Anatomy with Myocardial Perfusion Data

摘要

BackgroundAccurate alignment between cardiac CT angiographic studies (CTA) and nuclear perfusion images is crucial for improved diagnosis of coronary artery disease. This study evaluated in an animal model the accuracy of a CTA fully automated biventricular segmentation algorithm, a necessary step for automatic and thus efficient PET/CT alignment.
