Abstract
A nuclear medicine image reconstruction method generates a reconstructed image () by performing iterative image in reconstruction () on nuclear medicine imaging data (). The iterative image reconstruction produces a sequence of update images (). During the iterative image reconstruction, a standardized uptake value (SUV) transform () is applied to convert an update image () to an update SUV image (). The SUV transform scales values of voxels of the update image to SUV values using scaling factors including at least a body size metric and a dose metric. During the iterative image reconstruction, at least one parameter used in an image update of the iterative image reconstruction is adjusted using the update SUV image. For example, a parameter of a prior or filter () incorporated into an image reconstruction update step () or used in filtering of an update image () may be adjusted.
