Paper Abstract

This paper presents a novel approach to automatically detect the end-diastolic (ED) and end-systolic (ES) frames from an X-ray left ventricular angiographical image sequence. ED and ES image detection is the first step for widely used left ventricular analysis in catheterization lab. However, due to the inherent difficulties of X-ray angiographical image, automatic ED and ES frame selection is a challenging task and still remains unsolved. The current clinical practice uses manual selection, which is not only time consuming but also sensitive to different persons at different time. In this paper, we propose to formulate the X-ray angiogram by a dynamical graphical model. Then the posterior density of the left ventricular state is estimated by using Bayesian probability density propagation and adaptive background modeling. Preliminary experimental results have demonstrated the superior performance of the proposed algorithm on clinical data.
