1. A system, comprising: a data store for storing an input signal data received from an MRI or NMR system, where the input signal data includes two or more related sets of image data; a first logic for processing the input signal data into a processed signal data, where the effects of one or more undesired phase shifting events on the input signal data are reduced in the processed signal data; and a second logic for processing the processed signal data to quantify the effects of one or more desired phase shifting events.
