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.

Although the scatter corrections take most of the time, if the voxel size of the reconstruction were decreased, the time for projective tomography would increase, perhaps as the inverse fourth power of the voxel size, whereas the time to compute scatter corrections would increase much less quickly.
Step 3: Smooth the image with Gauss filtering, and execute Steps 4-6 for each voxel.
Assumed [P.sub.6] (x, y, z) is any point within the voxel, it is necessary to convert its spatial coordinates into image coordinates ([i.sub.6], [j.sub.6], [k.sub.6]) in order to calculate the value of voxel, where [i.sub.6] = x/[DELTA]x, [j.sub.6] = y/[DELTA]y, [k.sub.6] = z/[DELTA]z are represented respectively the position index of the voxel in directions of X, Y, and Z in the body data.
Today Voxel is a wholly-owned subsidiary of Holorad, a privately held corporation headquartered in Salt Lake City, Utah.
Currently, there are 12 different brands of these devices in the market with the FOV size varying between 16x18 and 19x24 cm, and the voxel size varying between 0.08 and 0.20 mm (1, 13).
Binary masks for each of the 10 ROIs were subsequently created in the automated pipeline before applying it on the processed images to collect SUV voxels. Each voxel from the labelled ROIs obtained from segmentation was used in this process.
A proper region space [OMEGA] is selected and a voxel is compared with the voxels in [OMEGA].
Therefore, the aim of this study was to determine a cutoff voxel size value for the assessment of root canal filling voids in micro-CT images as compared to those obtained with nano-CT scans as reference images.
(2) To obtain a more accurate indication of age-related brain regions, different thresholds of voxel values were set and compared correlations between SUVR mean and age using Pearson correlation.

The method is based on a voxel classifier, trained with features obtained from the eigenanalysis of the Hessian matrix corresponding to every voxel in the ultrasound volume.
