Abstract
A method for reconstructing medical images comprises: identifying a plurality of organs in a body of a subject based on an anatomic image; assigning a plurality of voxels in the body to respective ones of the plurality of organs based on the anatomic image; and reconstructing activity images of the body using respectively different processing for the voxels assigned to each respective one of the plurality of organs.
Claims16
A method for reconstructing medical images, comprising:
- identifying a plurality of organs in a body of a subject based on an anatomic image;
- assigning a plurality of voxels in the body to respective ones of the plurality of organs based on the anatomic image;
- and
- reconstructing activity images of the body using respectively different processing for the voxels assigned to each respective one of the plurality of organs, wherein the reconstructing includes performing regularization for one or more selected organs based on information from the anatomic image and wherein the reconstructing includes performing regularization for one or more selected organs based on information from the anatomic image.
A system for reconstructing medical images, comprising:
- a non-transitory, machine-readable storage medium coupled to receive medical image data, the machine-readable storage medium containing instructions;
- and
- a processor coupled to the machine-readable storage medium for executing the instructions, wherein the instructions configure the processor for performing a method comprising:
- identifying a plurality of organs in a body of a subject based on an anatomic image;
- assigning a plurality of voxels in the body to respective ones of the plurality of organs based on the anatomic image;
- and
- reconstructing activity images of the body using respectively different processing for the voxels assigned to each respective one of the plurality of organs, wherein the reconstructing includes performing regularization for one or more selected organs based on information from the anatomic image and wherein the selected organs are selected based on a correlation between voxel values of the anatomic image and voxel values of the activity images.
A non-transitory, machine-readable storage medium containing instructions, such that when a processor executes the instructions, the instructions configure the processor for reconstructing medical images by:
- identifying a plurality of organs in a body of a subject based on an anatomic image;
- assigning a plurality of voxels in the body to respective ones of the plurality of organs based on the anatomic image;
- and
- reconstructing activity images of the body using respectively different processing for the voxels assigned to each respective one of the plurality of organs, wherein the reconstructing includes performing regularization for one or more selected organs based on information from the anatomic image and wherein the selected organs are selected based on a correlation between voxel values of the anatomic image and voxel values of the activity images.
