Localization and Atlas-based Segmentation of the Heart from Cardiac MR Images: Validation with a Large Clinical Trial

摘要：

This paper presents an automatic method to find and segment the boarders of the left and right ventricles (LV and RV) from the middle short axis (SA) slice of a functional cardiac MRI study. The segmentation is implemented using a new atlas-based registration framework which is able to integrate boundary, intensity and anatomical information. The method is shown to be accurate, robust and reliable in a clinical trial of 330 patients with a range of cardiac and vascular disease. The method failed in only two cases, and showed high agreement with expert observers in the remaining 328.
