Direct Estimation of Cardiac Bi-ventricular Volumes with Regression Forests

Abstract: Abstract. Accurate estimation of ventricular volumes plays an essential role in clinical diagnosis of cardiac diseases. Existing methods either rely on segmentation or are restricted to direct estimation of the left ventricle. In this paper, we propose a novel method for direct and joint volume estimation of bi-ventricles, i.e., the left and right ventricles, without segmentation and user inputs. Based on the cardiac image representation by multiple and complementary features, we adopt regression forests to jo… Show more

“…Direct estimation of cardiac volumes has started to generate increasing interest due to the avoidance of intermediate segmentation (Afshin et al, 2012a;Wang et al, 2014;Zhen et al, 2014d). To directly estimate the ejection fraction of the LV, global image statistics are used to calculate LV volumes in (Afshin et al, 2012a).…”

“…However, segmentation itself is an extremely challenging problem which in clinical practise physicians are not interested in. Direct estimation methods which remove the segmentation step become attractive in cardiac function diagnosis and ventricular estimation due to its efficiency and clinical significance (Afshin et al, 2012a,b;Wang et al, 2014;Afshin et al, 2014;Zettinig et al, 2014;Zhen et al, 2014d;Wang et al, 2013;Zhen et al, 2015a). A comprehensive study of methods for cardiac ventricular volume estimation has been conducted in (Zhen et al, 2014c) showing that direct estimation methods provide more accurate estimation than segmentation-based methods for both left and right ventricles (LV and RV).…”

“…Segmentationonly class of supervised techniques, on the other hand, mainly focuses on featurebased representation of the myocardium. Texture information is generally considered as an effective feature representation of the myocardium for standard CINE MR images [22]. Patch-based static discriminative dictionary learning technique (SJTAD) [16] and Multi-scale Appearance Dictionary Learning technique [4] have achieved high accuracy and are considered as state-of-the-art mechanisms for supervised myocardial segmentation.…”
