Method and system for performing image registration
First Claim
Patent Images
1. A method for performing image registration, comprising the steps of:
- obtaining a reference image dataset and at least one other target image dataset;
defining an image mask for a region of interest in the reference image dataset;
differently weighting respective sub-regions within the image mask, wherein each sub-region corresponds to a different respective anatomical structure; and
registering a corresponding region of interest in the at least one other target image dataset with the image mask, using a similarity metric, wherein the similarity metric is computed based on one or more voxels in the region of interest defined by the image mask and using the respective weights associated with each voxel.

Abstract
A method for performing image registration is provided. The method comprises obtaining a reference image dataset and a target image dataset and defining an image mask for a region of interest in the reference image dataset. The method further comprises registering a corresponding region of interest in the target image dataset with the image mask, using a similarity metric, wherein the similarity metric is computed based on one or more voxels in the region of interest defined by the image mask.

15. A system, comprising:
-
at least one imaging system configured to obtain a reference image dataset and at least one other target image dataset; and a processing module in communication with the at least one imaging system and configured to define an image mask for a region of interest in the reference image dataset, to differently weight respective sub-regions within the image mask, wherein each sub-region corresponds to a different respective anatomical structure, and to register a corresponding region of interest in the at least one other target image dataset with the image mask, using a similarity metric, wherein the similarity metric is computed based on one or more voxels in the region of interest defined by the image mask and using the respective weights associated with each voxel. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
