Abstract
A magnetic resonance elastography (MRE) scan is performed using an array of transducers for applying a strain wave to tissues in a region of interest. A calibration process is performed prior to the scan in which the strain wave produced by each transducer in the array is imaged using an MRE pulse sequence so that information may be acquired that enables each transducer to be properly driven during a subsequent MRE scan.
