MULTIPARAMETRIC IMAGE FUSION AND SEGMENTATION

MULTIPARAMETRIC IMAGE FUSION AND SEGMENTATION

Multiparametric Magnetic Resonance Imaging (MRI) produces large amounts of high dimensional data for radiologists to read. Currently, radiologists integrate multiparametric MRI data visually to identify meaningful structures within the data. In this project, we developed different novel visualization and clustering techniques based on manifold learning and deep learning for integration of multidimensional radiological data. The algorithms developed in this project include Consensus Similarity Mapping (CSM) and multiparametric deep network (MPDN). We demonstrate the performance of our algorithms on well-known synthetic datasets as well as multiparametric magnetic resonance imaging (MRI) data.
