OVERALL VISION:

To close the loop between imaging, image analysis, and biomarker/predictive model, so as to inform the optimal task-specific acquisition and reconstruction of raw image data.

Machine Learning on Multiparameter MRI

Self-Organizing Maps for Differential Diagnosis. Activation maps of two classes of tumors are shown, with the top five neurons most characteristic of each tumor class indicated by green X's and red diamonds. Also shown are the normalized intensities on T2W, T1W unenhanced, T1W-CE arterial phase, and T1W-CE venous phase MRI that correspond to each neuron.
