The segmentation is a step of great importance and difficulty in the analysis of digital images, much more when it is about medical images. Conscious of the value that the processing can offer to the treatment of compression for varicose veins, this article takes the first step in the development of a dynamic geometric model of the leg that would allow to evaluate the effect of the average of compression as a treatment of the varicose veins A designed protocol is shown for the acquisition of images in RM of inferior limbs, the results of the implementation of several methods of segmentation of these images, that allow to obtain different tissues on hand: bone, muscle, subcutaneous greasy tissue and vasciilar system. Finally 3D representations of the segmerited volumes are shown. The implementations are put together in a series of interactive modules that allow a user to execute the segmentations and to visualize the results.
