Computer-aided detection of exophytic renal lesions on non-contrast CT images
We developed a novel computer-aided diagnosis system to detect renal lesions on non-contrast CT images. We designed an efficient belief propagation method to accurately segment kidneys on non-contrast CT images. Manifold diffusion was developed to accurately and smoothly measure shape changes on the kidney surface. We detected renal lesions with local maximum diffusion response on the kidney surface graph. Manifold diffusion achieved 95% sensitivity with 15 false positives per patient on 167 patients.
