The kidney stone, also known as renal calculus can be identified by Computed Tomography imaging. There are various problems associated with this imaging technique such as blurry image, the low resolution of CT scan image, the similarity of renal calculi with other parts near kidney and prediction of stone in the image of the kidney. Computed Tomography takes X-rays through the required slices from the body. The image first goes through various preprocessing stages, then it is segmented and finally, the number of stones and their respective area are identified to help the doctor to analyze the patient's condition. This study has developed an automatic renal calculi detection system using the digital image processing techniques in CT scan images.
