1. A method of synthetic image generation for magnetic resonance (MR) imaging, the method comprising: receiving a plurality of MR imaging data sets, each data set comprising a set of pixel values acquired at a different value for at least one MR acquisition parameter; determining a response value for a particular property of tissues for each pixel, based on a calculated fit of each pixel to a property response model; generating a synthetic image for a selected value of the at least one MR acquisition parameter, based on the determined response value for each pixel; providing an option to dynamically change the selected value of the at least one MR acquisition parameter; and in response to any change in the selected value of the at least one MR acquisition parameter, re-generating the synthetic image; wherein the at least one MR acquisition parameter is echo time (TE) or inversion time (TI); wherein if the MR acquisition parameter is TE, the response value is T2 and proton density (PD), and the property response model is a decay model; and wherein if the MR acquisition parameter is TI, the response value is T1, and the property response model is a recovery model.
