Abstract
A registration technique is provided that can combine one or more related registrations to enhance accuracy of a registration of image volumes. A registration relationship between a first source volume and a target volume and a registration relationship between the first source volume and a second source volume are concatenated to provide an estimate of a registration relationship between the second source volume and the target volume. The estimate is utilized to inform the direct registration of the second source volume to the target volume or utilized in place of the direct registration.
Claims21
A system, comprising:
- a processor coupled to memory storing computer-executable instructions that, when executed by the processor, configure the processor to:
- respectively register a first image to each reference image of a set of reference images to generate a set of registration relationships between the first image to each reference image;
- and
- combine each registration relationship of the set of registration relationships to generate combined registration information;
- and
- generate a final registration of the first image to a template space based on the combined registration information.
A system, comprising:
- a processor coupled to memory storing computer-executable instructions that, when executed by the processor, configure the processor to:
- register each pair of images from a library of images to generate a set of intra-library registrations;
- combine each registration from the set of intra-library registrations with a predetermined registration relationship to a reference template to generate a set of estimated registrations that includes estimated registrations of each image from the library of images to the reference template;
- and
- register each image from the library of images to the reference template based on respective estimates from the set of estimated registrations.
A non-transitory, computer-readable storage medium having stored thereon on computer-executable instructions that, when executed, configure a processor to:
- respectively register a first image to each reference image of a set of reference images to generate a set of registration relationships between the first image to each reference image;
- and
- combine each registration relationship of the set of registration relationships to generate combined registration information;
- and
- generate a final registration of the first image to a template space based on the combined registration information.
The non-transitory, computer-readable storage medium of claim of 17, further storing instructions that configure the processor to generate the final registration according to an optimization function that determines whether a convergence criterion is satisfied based on the average score.
