Contrast Enhanced Ultrasound Images Restoration

In this paper, we propose a new anisotropic diffusion scheme to restore contrast enhanced ultrasound images for a better quantification of liver arterial perfusion. We exploit the image statistics to define a new edge stopping function. The method has been tested on liver lesions. The results show that the assessment of lesion vascularization from our process can potentially be used for the diagnostic of liver carcinoma.
