A fast mean-field method for large-scale high-dimensional data and its application in colonic polyp detection at CT colonography
Found in: Neural Networks, IEEE - INNS - ENNS International Joint Conference on
By Shijun Wang, Ronald M. Summers, Changshui Zhang
Issue Date:June 2009
pp. 3251-3258
In this paper, we propose a fast mean-field method called LHMF to handle probabilistic models of large-scale data in high dimensional space. By using diffusion map locally linear embedding method which is a non-linear dimensionality reduction method, we fi...
Asymmetric Affinity in Fuzzy Connectedness Segmentation for Oral Contrast-Enhances CT Colonography
Found in: Computer-Based Medical Systems, IEEE Symposium on
By Marek Franaszek, Ronald M. Summers
Issue Date:June 2006
pp. 419-423
In oral contrast-enhanced CT colonography, patients are given barium- or iodine-containing solutions to drink to tag out remnants of stool and residual fluid in the colon. Frequently, residual fecal matter absorbs more tagging material and appears much bri...
A Scalable Reference Standard of Visual Similarity for a Content-Based Image Retrieval System
Found in: Healthcare Informatics, Imaging and Systems Biology, IEEE International Conference on
By Jessica S. Faruque,Daniel L. Rubin,Christopher F. Beaulieu,Jarrett Rosenberg,Aya Kamaya,Grace Tye,Sandy Napel,Ronald M. Summers
Issue Date:July 2011
pp. 158-165
In order to develop content based image retrieval (CBIR) systems, a robust reference standard of similarity between pairs of images is required, but challenging to create given the large number of pair-wise comparisons. We demonstrated a novel method of cr...
Teniae Coli Guided Navigation and Registration for Virtual Colonoscopy
Found in: Visualization Conference, IEEE
By Adam Huang, Dave Roy, Marek Franaszek, Ronald M. Summers
Issue Date:October 2005
pp. 36
We present a new method for guiding virtual colonoscopic navigation and registration by using teniae coli as anatomical landmarks. As most existing protocols require a patient to be scanned in both supine and prone positions to increase sensitivity in dete...
