Description

This invention presents a method for producing multiple MR images with different contrast from a single image acquisition. (MR T2) The methodology is used to enhance the T2 related contrast in an MRI image acquired at, but no restricted to, just-enough-to-highlight-T2, repetition time so as to produce a computed mosaic of the same image at different repetition (TR) and echo (TE) times. This leads to substantial reduction in scan time and simultaneous provision of multiple snapshots of the same image at different TR and TE time settings. The enhanced mapping is performed using a feature-guided non-linear equalization technique. Feature bank based on intensity distribution is derived using a priori training images acquired for a range of TR and TE times.
