Abstract: Due to the unpredictable location, fuzzy texture, and diverse shape, accurate segmentation of the kidney tumor in CT images is an important yet challenging task. The segmentation of kidneys and kidney tumors is a challenging process for physicians, thereby representing an area for further study. To aid machine-learning-based approaches to this problem, 210 such CT scans were publicly released along with segmentation masks created manually by medical students under the supervision of an experienced urologic oncology surgeon. First, the location of tumors may vary significantly from patient to patient. Due to the wide variety in kidney and kidney tumor morphology, there is … 2019 Kidney Tumor Segmentation Challenge Method Manuscript MengLei Jiao, Hong Liu Beijing Key Laboratory of Mobile Computing and Pervasive Device Institute of Computing Technology, Chinese Academy of Sciences, Beijing, China Abstract.
