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.

4) The mesh consists in 100*100*20 voxels (Figure 6).
Voxels with other dual-energy behaviors remain grey.
Here, the observations are random voxels inside the mask of the grains.
They compared the cognitive abilities of patients with damage to a particular voxel or cluster of voxels with those of patients without injuries in those brain regions.
TORONTO, April 19, 2012 /PRNewswire/ - Geosoft has announced the availability of its 2012 Software Release, including updates to Oasis montaj, Target, Target for ArcGIS and GM-SYS Modelling software, and the new release of Geosoft VOXI Earth Modelling, a geophysical inversion software service that generates 3D voxel models from airborne or ground gravity and magnetic data.
Another interpretation is that, for every voxel in the brain, the MRI signal is measured at 150 time points over the duration of the task, resulting in a time course plot for every voxel in the brain (Fig.
S<-voxel //S is the aggregate containing the voxel satisfies the growing criterion If (the 18 neighbors in the adjacent slices satisfy the growing criterion) S<-voxel //S is the aggregate containing the voxel satisfies the growing criterion
The signals from the voxels appear on a magnetic resonance (MR) image as varying degrees of light and dark.
14) With the described set-up, micron resolution can be reached, in this paper resulting in scans with voxels sizing approximately 2 x 2 x 2 [micro]m with 2 (16) greyscale levels.
The chosen method for visualization is Marching Cubes (Lorensen & Cline, 1987), an algorithm that takes each volume cell (a cube with four neighbour vertices or voxels on one slice and the other four on an adjacent slice) and computes the intersections of these cubes with an isosurface, thus extracting a polygonal mesh (the contour surface of the 3D shape).
After BOLD signals have been measured and the patient has been released from the machine, researchers must sort the red-hot voxels from the dead fish.
