3D general lesion segmentation in CT

This paper describes a general purpose algorithm to segment any kind of lesions in CT images. The algorithm expects a click or a stroke inside the lesion from the user and learns gray level properties on the fly. It then uses the random walker algorithm and combines multiple 2D segmentation results to produce the final 3D segmentation of the lesion. Quantitative evaluation on 293 lesions demonstrates that the method is ready for clinical use.
