In this paper, we describe a speckle noise reduction method for ultrasound images based on the undecimated wavelet packet transform (UWPT). Recent wavelet domain despeckling methods always assume speckle noise of ultrasound images as oversimplified distributions and use logarithmic transformation to suppress speckle noise in a homomorphic filtering framework. The proposed method avoids that unnatural...
High intensity focused ultrasound (HIFU) has been investigated as a new technique for treating tumors in clinical applications. Detecting HIFU induced lesions in medical imaging is an important method to monitor and guide the HIFU therapies. In this paper, we propose an ultrasound image enhancement method for HIFU lesion detection and measurement based on the combination of the GenLik method and the...
