Embodiment Construction

[0023] first reference Figure 4 , illustrates a system 400 including a computing system 402 and an imaging system 404 . In a variation, imaging system 404 can be omitted. In a variation, image data processed by computing system 402 can be obtained from an image storage device, which may be part of computing system 402, that is remotely located relative to (e.g., used with) computing system 402 its hardware memory) or distributed between computing system 402 and a remote location.

[0024] In the illustrated embodiment, imaging system 404 includes a computed tomography (CT) scanner. CT scanner 404 includes a generally fixed gantry 406 and a rotating gantry 408 rotatably supported by fixed gantry 406 . The rotating gantry 408 rotates about an examination region 410 about a longitudinal or z-axis. A radiation source 412, such as an X-ray tube, is supported by the rotating gantry 408 and emits a radiation beam. A radiation sensitive detector array 414 detects radiation passi...

Abstract

A method includes obtaining first image data that includes voxel representing a structure of interest. The structure of interest includes a plurality of different sub-structures. The method further includes segmenting a volume of the first image data that includes only a single sub-structure for each of the plurality of different sub-structures. The method further includes creating a different local coordinate system for each of the different sub-structures for each of the volumes. The method further includes visually presenting the structure of interest through separate visual presentations of sets of reformatted images for each of the individual plurality of different sub-structures. A set of reformatted images for a sub- structure includes different cut planes generated from a corresponding segmented volume of the segmented volumes and the local coordinate system for the sub-structure.

Description

technical field [0001] The present invention relates generally to volumetric image data visualization and is described with the particular application of computed tomography (CT). However, the invention is also applicable to other imaging modalities. Background technique [0002] CT scanners typically include an x-ray tube mounted on a rotatable gantry opposite a detector array across the examination area. The rotatable gantry and thus the x-ray tube rotate around the examination field. The x-ray tube is configured to emit radiation that passes through the examination region and is detected by the detector array. In response, the detector array generates and outputs a signal indicative of the detected radiation. The signals are reconstructed to generate three-dimensional (3D) volumetric image data that can be processed to generate one or more images of the structure of interest. Efficient visualization of image data is crucial to support diagnosis and to save reading tim...
