Left ventricular function analyzer and its application
The design of an image processor for the total evaluation of cardiac function is described. The system quantitatively evaluates cardiac function efficiently and accurately. Its functions include automatic boundary extraction, computation of volume, and three-dimensional display of a left ventricle. The method of automatic boundary extraction comprises: (1) processing to vignette and then correct blur using a Hadamard transformation, and (2) processing to extract the boundary automatically and reliably. Computation of volume is achieved using a gray-level method which computes blood volume by using three-dimensional information inherent in the X-ray image. The three-dimensional display is produced using a gray-level and spline functions.
