Abstract:
1. A method for medical imaging with motion analysis, the method comprising: obtaining a sequence of frames of data representing a region at different times, the region including a plurality of different spatial locations; identifying from a sequence of frames using a processor, first and second phases of sinusoids representing cyclically varying imaging values over time for first and second spatial locations, respectively, the phases being of an offset of the sinusoids relative to a wave representing a physiological cycle, each of the first and second locations being in each scan of a plurality of scans, the imaging values from each of the first and second locations being used separately for the identifying, the first and second phases being phase differences of the sinusoids of the variations of the imaging values over time with the physiological cycle, the phase differences comprising an amount of the offset, wherein the identifying is performed for a plurality of spatial locations including the first and second spatial locations and other spatial locations in at least three segment regions; determining a quantity as a function of the first and second phases; and displaying, on a display, an image as a function of the quantity, the image having a phase axis and a location axis, a curve of the first, second and other phases as a function of the first, second, and other spatial locations, a straight line fit to the first, second, and other phases, and an indication of variance for each of the first, second, and other phases.
