Metastatic melanoma is a highly heterogeneous tumor; thus, methods to analyze tumor-derived cells circulating in blood should address this diversity. Taking this into account, we analyzed, using multiparametric flow cytometry, the co-expression of the melanoma markers melanoma cell adhesion molecule and melanoma-associated chondroitin sulphate proteoglycan(More)
We propose a multigrid level-set segmentation algorithm for the segmentation of 3D high-frequency ultrasound images. Target applications include the quantitative analysis of lesions or normal structures within cutaneous and superficial subcutaneous tissues. The method is based on an a non-parametric region-based cost function, the Hellinger distance, which(More)
