| Abstract | Many studies have shown that multiparametric magnetic resonance imaging (MRI), which combines MR spectroscopic imaging (MRSI), T2 weighted MRI, diffusion weighted imaging (DWI) and dynamic contrast enhanced (DCE) MRI, leads to more accurate cancerous tissue localization for prostate cancer patients. However, manual delineation with multiparametric MRI datasets requires a high level of expertise, is a labor-intensive procedure and prone to inter- and intra-observer variability. In this paper, we present an automatic prostate cancer segmentation method based on fuzzy information fusion of multiparametric MRI. In this method, fuzzy c-means clustering (FCM) is first used to obtain fuzzy information related to cancerous tissue shown on each kind of MRI data. Then, an adaptive fuzzy fusion operator based on Bayesian model with a Gibbs penalty term is designed to fuse fuzzy sets obtained by FCM and produces a membership degree map for the region of interest. Based on this map, a decision of cancer regions can be made. In this study, datasets from biopsy-confirmed prostate cancer patients are used to test this method. Experimental results have shown that the proposed method can well localize cancerous regions not only in peripheral zones but also in transition zones of the prostates. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
