Résumé

The problem of mathematical data processing of gated blood pool SPECT is considered. Gated blood pool SPECT is a radionuclide tomographic method which due to its high diagnostic accuracy and the large volume of the data is one of the most popular in the problems of estimation and visualization of the pumping function of heart ventricles. To solve the problem the following algorithms: building parametric heart images using wavelet transforms; determining volumes of left and right ventricles; building activity/time curve reflecting changes of blood filling of ventricles; building parametric images presented in the form of polar diagrams on whose grounds it is possible to judge time sequence of various ventricle departments movement are suggested. The problem of determine basic diagnostic parameters that characterize the work of heart ventricles is also defined. Bibliogr. 21. Il. 7.

Détail

Keywords: wavelet, polar diagrams, gated blood pool SPECT.
