Abstract
We previously reported a method for automated detection of ventricular contours in cardiac magnetic resonance (MR) image. However, in the case that the gray-level difference between the ventricles and surrounding tissues is extremely obscure, this technique may not work well. To overcome the shortcomings, in this paper we present an improved algorithm to enable us to extract the contours of ventricles from cardiac MR images having extremely low contrast. The technique is based on our previously reported algorithm by incorporating a 2-step preprocessing procedure. Namely, we first automatically determine the gray value of the boundary between ventricles and surrounding tissues, and then enhance the location of edges to make the boundary clearer. Experimental results confirmed the superiority of our improved method over the previous technique and other commonly used methods.
