Methods and systems for selective recombination of reconstructed image regions

Abstract

Various methods and systems are provided for selective recombination of reconstructed nuclear medicine (NM) image regions. The method may include acquiring and sorting imaging scan data that includes data elements having different accuracy properties into two or more different groups using an anticipated accuracy metric, reconstructing a first initial image volume from a first group having a highest anticipated accuracy metric of the two or more different groups, reconstructing a second initial image volume from a combined data group comprising data of the first group and a second group of the two or more different groups, wherein the second group has a lower anticipated accuracy metric compared to the first group, and generating an optimized image volume using corresponding image values from the first initial image volume, the second initial image volume, and an output of a high spatial frequencies detection (HSFD) operator applied to the first initial image volume.
