Phase-cycled balanced TFE disentangled using configuration states: Multi-purpose imaging for the MRI-Linac workflow

Phase cycled bGRE images disentangled into configuration modes can be used to generate alternative signal contrasts for for example for radiotherapy delineation purposes while simultaneously geometrical errors due to B0 inhomogeneity can be quantified. Numerical simulations show the change in modulation for different configurations states. In vivo experiments on the male pelvis are used to illustrate the changed image contrast and obtained B0 map against the reference method.
