Brain Tissue Classification of Magnetic Resonance Images Using Conditional Random Fields

by unknown authors
"... In this project, I propose the application of a discriminative framework for segmentation of a T1weighted magnetic resonance image(MRI). The use of Gaussian mixture models (GMM) is fairly ubiquitous in processing brain images for statistical analysis. This generative framework makes several assumpti ..."

Coil sensitivity encoding for fast MRI. In:

by Klaas P Pruessmann , Markus Weiger , Markus B Scheidegger , Peter Boesiger - Proceedings of the ISMRM 6th Annual Meeting, , 1998
"... New theoretical and practical concepts are presented for considerably enhancing the performance of magnetic resonance imaging (MRI) by means of arrays of multiple receiver coils. Sensitivity encoding (SENSE) is based on the fact that receiver sensitivity generally has an encoding effect complementa ..."

or collimation but by spectral analysis. The idea of Lauterbur (1) to encode object contrast in the resonance spectrum by a magnetic field gradient forms the exclusive basis of signal localization in Fourier imaging. However powerful, the gradient-encoding concept implies a fundamental restriction. Only one

Classification of

In proposed methodology three supervised neural networks has been used: Back Propagation Algorithm (BPA), Learning Vector Quantization (LVQ) and Radial Basis Function (RBF). The features of magnetic resonance images have been reduced, using principal component analysis (PCA
