1. A nuclear medicine image reconstruction device comprising:

  • an electronic processor; and

    a non-transitory storage medium storing instructions readable and executable by the electronic processor to perform an image reconstruction method including;

    generating a reconstructed image by performing iterative image reconstruction on nuclear medicine imaging data wherein the iterative image reconstruction produces a sequence of update images; and

    during the iterative image reconstruction, applying a standardized uptake value (SUV) transform to convert an update image to an update SUV image and adjusting at least one parameter of the iterative image reconstruction using the update SUV image;

    wherein the SUV transform operates to scale values of voxels of the update image to SUV values using scaling factors including at least a body size metric and a dose metric.
