Abstract
A method and apparatus of generating a modified segmented structure is disclosed. This modified segmented structure subtracts pixels or voxels in an inward direction from the segmented structure to create a smaller volume or area than the segmented structure. Analysis of the smaller volume can be useful in generating custom volumes, which can then be processed to improve visualization inside the custom volume.

A method comprising:
- loading an imaging dataset into an image processing computer system;
- performing an initial segmentation of a structure within the imaging dataset;
- determining an outer surface of the structure;
- determining at least one layer of pixels or voxels internal to the outer surface of the structure
- wherein the at least one layer of pixels or voxels is not conformal with the outer surface of the structure, and
- wherein a non-conformal shape of said at least one layer of pixels or voxels is determined based on at least one of the group of:
- said at least one layer of pixels' data units relative to said structure's pixels data units;
- and
- said at least one layer of voxels' data units relative to said structure's voxels data units;
- and
- subtracting the at least one layer of pixels or voxels internal to the outer surface of the structure to generate a modified segmented structure.

An apparatus comprising:
- an IO device;
- and
- an image processor in communication with the IO device, the image processors comprising a program stored on a computer-readable non-transitory media, the program comprising instructions that perform:

- determining at least one layer of pixels or voxels internal to the first boundary
- wherein the one layer of pixels or voxels is not conformal with the first boundary, and
- wherein a non-conformal shape of said at least one layer of pixels or voxels is determined based on at least one of the group of:
- said at least one layer of pixels' data units relative to said structure's pixels data units;
- and
- said at least one layer of voxels' data units relative to said structure's voxels data units;
- and
- generating a second boundary wherein the second boundary is generated by moving inward the at least one layer of pixels or voxels from the first boundary.
