In the paper novel application of the level set method to heart segmentation in ultrasound echocardiography is addressed. In the presented approach region of interest of the ultrasound image is calculated by means of Hough transform and speckle noise is reduced by anisotropic diffusion filter. The method is initially validated on USG like simulated noisy images. In article segmentation results for real echocardiograpic images are also shown.

W artykule zaprezentowano nowe zastosowanie metody zbiorów poziomicowych do segmentacji danych echokardiograficznych. W proponowanym podejściu przedstawiono sposób wyznaczenia obszaru zainteresowań w obrazach ultrasonograficznych bazujące na transformacji Hough'a oraz redukcję zakłóceń wykorzystującą anizotropowe filtry dyfuzyjne. Metoda została wstępnie sprawdzona na modelu wraz symulacją zakłóceń. Przedstawiono wyniki segmentacji dla rzeczywistych obrazów echokardiograficznych.
