| Abstract: |
This work presents an algorithm for the segmentation of myocardial regions in echocardiography imaging based on the statistics of the radiofrequency image. We formulate the problem of segmentation in a Maximum Likelihood framework using the Generalized Gaussian distribution. We minimize the resulting functional using a Radial Basis Functions-based multiphase level set model. Numerical results obtained on both simulation and in vivo data demonstrate the capacity of our approach to segment myocardial regions in echocardiography. |
