Quick quantitative assessment cardiac function and strain measurement used from magnetic resonance imaging (MRI) image circuit at least partly onboard or communicate MRI scanner and at least one described display, which includes at least one processor. The heart of the patient of the cardiac MRI length axial plane of multiple series is obtained, wherein obtaining the cardiac imaging session of the patient of different single beats in each series magnetic resonance image, that is, five minutes or more initiative sweep time come from and patient scan device Measurement strains the heart of the patient of myocardium heart tissue, the heart of the cardiac MRI patient based on the multiple series With the longitudinal and circumferential cardiac module of generation, there is multiple adjacent compartments composition, wherein compartment is coloud coding, according to the strain of measurement.
