Abstract
In this work, We proposed a two-stage method for segmentation of kidneys and kidney tumors in CT images based on cascade Res-VNet. In the first stage, we consider the kidney and tumor as a whole region and use a cascade Res-VNet to do the segmentation. In the second stage, we firstly extract patches of ROIs based on the results of the first stage and use some tricks to improve precision. Then, we use another cascade Res-VNet to segment the tumor. Ouput from each stage are combined together as the final results.
