To further investigate the potential of the Extended Phase Graph algorithm, the reconstruction chain has been applied to the signal components created by Extended Phase Graph simulations. The resulting images can then be used as convolution kernels to simulate the sequence response to the parameter map of an object or to extract information about parameter sensitivity and influence from a sequence. An algorithm has been developed and utilized to generate images from object parameter maps to compare simulation results to measured images and to extract contrast information from a pulse sequence.
