voxel

[′väks·əl]
(computer science)
The smallest box-shaped part of a three-dimensional image or scan. Derived from volume pixel.

voxel

(jargon)
(By analogy with "pixel") Volume element.

The smallest distinguishable box-shaped part of a three-dimensional space. A particular voxel will be identified by the x, y and z coordinates of one of its eight corners, or perhaps its centre. The term is used in three dimensional modelling.

voxel

(VOlume piXEL) A three-dimensional pixel. A voxel represents a quantity of 3D data just as a pixel represents a point or cluster of points in 2D data. It is used in scientific and medical applications that process 3D images.

In order to avoid problems, we filtered the data prior the analysis by coring out the voxels belonging to a parallelepiped-shaped region wrapping the artefact.
To overcome this limitation while still performing a whole brain analysis, an alternative solution is to downsample the brain volume to get a smaller set of the time series from the mean signals of spatially contiguous voxels and apply correlation analysis on this set.
have proposed a rule-based transfer function based on the local frequency distribution of a voxels neighborhood [19].
Particles, Voxels, Metavoxels, and the system's various coordinate systems
Imported to the BT planning system isosurfaces that connect voxels with the same values were created and labeled as percentage of encompassed voxels.
Typically voxels don't have their coordinates encoded in their values, but instead the position of a voxel is based on its position relative to other voxels.
4) The mesh consists in 100*100*20 voxels (Figure 6).
Reconstruction of an industrial component based on the projected image slices leads to a voxel--the 3D analogue of a pixel--model, where the grey value of the voxels is a measure of the linear attenuation coefficient of the material.
The decomposition process splits and structures the environment by associating the facets to the voxels comprising terminal nodes of the octal tree.
In the background, Freeform automatically converts the voxels and mesh data into high-quality NURBS surfaces, which can then be combined with other solid models or exported to other programs requiring surface data (such as for generating tool paths in CAM).
