Image processing via a modified segmented structure
View Patent ↗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.

12. The method of claim 11 further comprising wherein the additional image processing is used to determine a dose of a pharmaceutical.
13. The method of claim 1 further comprising wherein additional non-contiguous pixels or voxels are subtracted from said modified segmented structure to form a further modified segmented structure.
14. The method of claim 1 further comprising wherein a visual appearance of the pixels or voxels in the modified segmented structure are modified independently from the pixels or voxels in the structure.
15. The method of claim 1 further comprising wherein the number of pixels or voxels included in the modified segmented structure is dependent upon at least one of the group consisting of: a patient demographics; a metadata; a type of pathology of clinical concern; a type of pathology in the structure; and, a size of the pathology in the structure.
16. The method of claim 1 further comprising wherein the modified segmented structure at a first time point and the modified segmented structure performed on the structure at a second time point are analyzed to determine interval change.
17. The method of claim 1 further comprises wherein a number of pixels or voxels included in the modified segmented structure can be varied by at least one of the group consisting of: a user input; and, an artificial intelligence input.
18. The method of claim 1 further comprising wherein an annotations is inputted to mark the modified segmented structure.
