Claim 16:
17. A system, comprising:
a detector array configured to acquire emission data during a scan of a subject; and
a controller operationally coupled to the detector array storing executable instructions in non-transitory memory that, when executed, cause the controller to:
reconstruct live images of the subject at pre-determined time points during the scan of the subject based on acquired emission data; and
track a motion of the subject in real-time during the scan based on a voxel-wise variation between image frames of the live images,
wherein to track the motion of the subject in real-time during the scan based on the voxel-wise variation between the image frames of the live images, includes additional executable instructions stored in the non-transitory memory that, when executed, cause the controller to:
determine a voxel-wise background noise of the scan of the subject;
determine the voxel-wise variation between the image frames relative to the voxel-wise background noise; and
output a real-time indication of the motion of the subject as one or more of a map indicating a magnitude of the voxel-wise variation at each voxel of the live images, a motion overlay on the live images, and a plot of a number of voxels having voxel-wise variations that exceed a threshold variation per image frame of the live images.
