The paper describes two particular applications of image processing for the purpose of analysis and simulation in the field of cardiology. The authors describe a method which allows for combining the 2D image obtained in ECHO examination, and a 3D model of heart, extracted from a set of CT slices. The fused image provides an intuitive view on the contractual function of heart, by overlaying the bull's eye diagram on the model of left ventricle. By preserving the spatial information, it is possible to accurately point the location of areas with impaired contractual function. Another method described by the authors, displays the use of the CT volume for simulation of echocardiography images for purpose of training application. A simple approach based on pixel brightness adaptation is used to provide images of sufficient training quality. At the same time authors highlight the issues of storage and run-time memory requirement of such application, and suggest a method of reducing the working set size.
