Figure 1From: Semi-automatic algorithm for construction of the left ventricular area variation curve over a complete cardiac cycle Block diagram of the proposed algorithm. The algorithm is composed of two image processing modules: preprocessing and segmentation. Four images - two adjacent images from two successive cardiac cycles - are used as inputs. The output is the area of the left ventricle at the corresponding time instant. The only operator interaction is a one-time-only manual placement of a barrier over the mitral valve.Back to article page
