Volume Body Renderer
First Claim
1. A computer-implemented method for identifying irregular volumes represented within volumetric input data, comprising the steps of:
- inputting one or more volume datasets comprising a multiplicity of three-dimensional cells;
establishing criteria describing properties of an irregular volume of interest;
processing each volume dataset, the processing comprising the steps of;
traversing from cell to cell of the volume dataset until a seed cell is identified having properties matching the criteria, the identified seed cell thereby belonging to an identified irregular volume;
identifying cells related to the seed cell by a predetermined relationship as belonging to the identified irregular volume;
storing in a data structure associated with each identified cell belonging to the identified irregular volume, attribute data describing properties of the identified cell, the attribute data including an indication of the location of the identified cell with respect to a predetermined frame of reference and including an identifier uniquely identifying the identified cell as belonging to the identified irregular volume; and
rendering at least a portion of the one or more volume datasets representing at least a portion of the identified irregular volume, the irregular volume portion comprising at least one internal cell and at least one boundary cell.

Abstract
Irregular volumes within one or more three-dimensional volume datasets are identified and extracted in response to criteria. The processing involves automatically finding a seed voxel or seed cell that meets the criteria and thus belongs to an irregular volume of interest, and then identifying cells related to the seed cell by one or more predetermined relationships that are therefore also to be grouped into that irregular volume. Information, which can be of any suitable type, identifying each such cell as being related to other cells and belonging to an irregular volume is stored in a suitable data structure. The location or similar neighborhood information and other data describing properties or attributes of the identified cell are also stored. Because the irregular volumes are extracted and pre-processed in this manner, operations including rendering them on a display and performing Boolean and arithmetic operations on them can readily be performed.
