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.

As an example of the program applied without scatter corrections, we take the case of a binary pattern with 128 x 128 x 1 voxels using the tube spectrum of Fig.
Step 5: Nodule and vessel enhancement filter are used to enhance the voxels.
ICA yields rs-fMRI networks by deriving spatially and temporally independent components from whole brain voxels. ICA examines multiple simultaneous voxel-to-voxel interactions of distinct networks in the brain (1).
Extreme positive deviations were significantly higher among healthy controls (1.08% of voxels), compared with bipolar patients and schizophrenia patients (0.79% and 0.78%, respectively).

VoxelMorph learned about common groups of voxels and anatomical shapes.
VR is a technique that can use all the voxels but does not allow the operator to change the translucency value using the density level.
Images were reconstructed in 3D using the CTPro 3D XT 3.0.3 (Nikon Metrology NV) in a subvolume of interest of 840 x 840 x 840 voxels. In the software VGStudio MAX 2.2 (Volume Graphics, Heidelberg, Germany), the images were converted to the Hounsfield scale, in which the air has value of 0 and water has value of 1000.
The transfer function designed through the histogram classifies the voxels with different degree of homogeneity by mapping them to different optic parameters.
Then, Pearson's correlation analysis was adopted between each voxel and the mirrored counterpart voxels within the interhemispheric symmetry in each subject.
These steps include (1) coregistration between sequences to reduce the effect of patient motion and converting it into DICOM format, (2) mean averaging of the 6 five-minute frames of the coregistered dynamic image set, (3) reorientation of the output images into a standard space with 160 x 160 x 96-voxel image grid of 1.5 mm cubic voxels, and (4) acquiring a uniform image with isotropic resolution of 8 mm full width at half maximum [24] (http://adni.loni.usc.edu/).
A thresholding (binarization) process was used, which entails processing the range of grey levels to obtain an image formed of black/white voxels only.
