  • Abstract
    In this paper the Nakagami-MRF model is proposed to model the backscattered echo from tissue and at the same time the spatial interaction found in the image. This paper investigates the efficiency of the model parameters to discriminate between normal and abnormal tissue by comparing the Nakagami-MRF parameters inside and surrounding the tumor. The study of the behavior of these latter parameters at different stages of the treatment are also undertaken to inform whether the tumor is cured or not. We conclude that our Markovian model is farther more informative than the use of the Nakagami distribution.
