A MATHEMATICAL MODEL OF THE LEFT VENTRICLE SURFACE AND A PROGRAM FOR VISUALIZATION AND ANALYSIS OF CARDIAC VENTRICLE FUNCTIONING

Abstract

The left heart chamber’s contractibility is an important part of heart diagnostics. Ultrasonographic pictures are very often used as the imaging method, as they are widely available, inexpensive and non-invasive. However, ultrasonographic pictures are very unclear, blurred and noisy, and thus very difficult for automatic analysis. To obtain a quick and useful analysis of ventricle performance, a special mathematical model has been created. The model can be used in contour detection, visualization of the heart’s motion and even in automatic surface analysis. We hope that in the future such programs could be incorporated into a general medical expert system.
