Methods and systems for selective recombination of reconstructed image regions

An imaging system, comprising:

• a detector array including a plurality of detectors;
• a display device;
• and
• a computing device communicatively coupled to the detector array and the display device, and configured with instructions in non-transitory memory that when executed cause the computing device to:
• acquire imaging scan data including data elements with different accuracy properties;
• sort the imaging scan data into two or more different groups based on an anticipated accuracy metric;
• reconstruct a high accuracy image from a first group, the first group comprising data elements with a highest anticipated accuracy metric;
• calculate image-based kernels for a guided hybrid-reconstruction algorithm;
• select a second group from the two or more different groups, the second group having a next highest accuracy data of a set of image data groups, with respect to the first group;
• reconstruct an updated high accuracy image from the high accuracy image, the image-based kernels, and the second group;
• update the image-based kernels for the guided hybrid-reconstruction algorithm, based on the updated high accuracy image;
• and
• output the updated high accuracy image for display on the display device.
