SYSTEMS AND METHODS FOR MOTION MITIGATION DETERMINATIONS

摘要

A method is provided that includes acquiring, with a detector comprising a plurality of rings defining corresponding slices, emission event data of an object of interest. The method also includes determining, with one or more processing units, an amount of motion for each of a plurality of segments, wherein each segment corresponds to less than an axial field of view (AFOV) of the detector. Further, the method includes performing, with the one or more processing units, motion mitigation for segments for which the amount of motion satisfies a threshold to provide motion mitigated data, and not performing motion mitigation for segments for which the amount of motion does not satisfy the threshold to provide non-mitigated data. Also, the method includes reconstructing an image using the motion mitigated data and the non-mitigated data. The method also includes displaying the image on a display.

1. A method comprising:
acquiring, with a detector comprising a plurality of rings defining corresponding slices, emission event data of an object of interest; determining, with one or more processing units, an amount of motion for each of a plurality of segments, wherein each segment comprises at least one of the slices and corresponds to less than an axial field of view (AFOV) of the detector; performing, with the one or more processing units, motion mitigation for segments for which the amount of motion satisfies a threshold to provide motion mitigated data, and not performing motion mitigation for segments for which the amount of motion does not satisfy the threshold to provide non-mitigated data; reconstructing, with the one or more processing units, an image using the motion mitigated data and the non-mitigated data; and displaying the image on a display.
