Multi-structure atlas and/or use thereof
First Claim
1. An image data processor, comprising:
- a structural image data processor that employs a multi-structure atlas to segment a region of interest from structural image data which includes tissue of interest and that segments the tissue of interests from the region of interest, wherein the structure is rib cage and the tissue of interest is lung lobe, and the multi-structure atlas is a rib cage/lung lobe atlas that includes a mapping that maps one or more ribs to a location of a boundary of a lung lobe, and the mapping includes a lung lobe region of interest, in a form of a least one of a point cloud on a surface of the lung or a 3D sheet across lung, through the rib case/lung lobe atlas; and
a functional image data processor that identifies the tissue of interest in functional image data based on the segmented tissue of interest.

Abstract
An image data processor (106) includes a structural image data processor (114) that employs a multi-structure atlas to segment a region of interest from structural image data that includes tissue of interest and that segments the tissue of interests from the region of interest. The image data processor further includes functional image data processor (116) that identifies the tissue of interest in functional image data based on the segmented tissue of interest. An image data processor includes a multi-structure atlas generator (104) that generates a multi-structure atlas. The multi-structure atlas physically maps structure to tissue of interest such that locate the structure in structural image data based on the multi-structure atlas localizes the tissue of interest to the region of interest.

7. An apparatus, comprising:
a processor that generates a multi-structure atlas, wherein the multi-structure atlas physically maps structure of interest to tissue of interest such that locating the structure of interest in structural image data based on the multi-structure atlas localizes the tissue of interest to the region of interest, wherein the processor generates the multi-structure atlas by; automatically segmenting the structure from the structural image data based on a predetermined algorithm; segmenting the tissue of interest from the structural image data with user interaction; mapping a physical spatial location of the segmented structure to the segment tissue of interest; and generating the multi-structure atlas based on a plurality of maps, wherein each map corresponds to sub-set of the image data for at least one of a different examination or a different subject. - View Dependent Claims (8, 9)
