1. A method comprising:

(a) determining a three-dimensional (3D) model, wherein the 3D model comprises a plurality of voxels, wherein each voxel of the plurality of voxels is associated with an illumination intensity value, wherein each voxel of the plurality of voxels is associated with a represented foreground of the 3D model or a represented background of the 3D model based on the respective illumination intensity value;

(b) causing display of an interactive element;

(c) receiving, via the interactive element, an indication of a selection of a seed voxel, wherein the seed voxel is associated with an illumination intensity of a specific value;

(d) determining one or more voxels of the plurality of voxels with illumination intensity values within a threshold range of the specific value, wherein the one or more voxels of the plurality of voxels with the illumination intensity values within the threshold range of the specific value are associated with a region of interest (ROI) within the 3D structure;

(e) causing one or more of a change in the illumination intensity values of one or more voxels associated with the ROI and a change of the illumination intensity values of one or more voxels of the plurality of voxels;

(f) causing, based on one or more of the change in the illumination intensity values of the one or more voxels associated with the ROI, and the change of the illumination intensity values of the one or more voxels of the plurality of voxels, one or more of a change in a represented shape of the ROI, and a change in a location of the ROI within the 3D model;

(g) repeating, based on an interaction with the interactive element via a user indicator, one or more of steps (c)-(f);

(h) associating, based on another interaction with the interactive element via the user indicator, one or more voxels of the plurality of voxels with a boundary within the ROI, wherein the illumination intensity values of the one or more voxels associated with the boundary match the specific value; and

(i) causing the illumination intensity value of one or more voxels within the boundary to match the specific value.

2. The method of claim 1 , wherein determining the 3D model comprises determining the 3D model based on image data.

3. The method of claim 2 , wherein the image data comprises one or more of magnetic resonance imaging (MRI) data or computed tomography (CT) image data.

determining another structure within the 3D model, wherein the another structure comprises another one or more voxels of the plurality of voxels;

receiving, an indication of a selection of the another one or more voxels;

receiving, based on the indication of the selection of the another one or more voxels, a request to change the coordinates of the another one or more voxels; and

changing, based on the request, the coordinates of the another one or more voxels, wherein changing the coordinates associates the another structure with the structure.
