In clinical practice, renal cancer diagnosis is performed by manual quantifications of tumor size and enhancement, which are time consuming and show high variability. We propose a computer-assisted clinical tool to assess and classify renal tumors in contrast-enhanced CT for the management and classification of kidney tumors. The quantification of lesions used level-sets and a statistical refinement...
In this paper, we propose an automated method for colon registration from supine and prone scans. Four anatomical salient points on the colon are distinguished first. Then correlation optimized warping (COW) method is applied to the segments defined by the anatomical landmarks to find better global registration based on local correlation of segments. To utilize more features along the colon centerline,...
In this paper, we propose an automated method for colon registration from supine and prone scans. We formulate the colon registration problem as time series matching along the centerline of the colon. Four anatomical salient points on the colon are distinguished first. They can be viewed as landmarks along the central path of the colon. Then correlation optimized warping is applied to the segments...
