Definition of voxel in English: voxelnounˈvɒksɛlˈväksəl (in computer-based modelling or graphic simulation) each of an array of elements of volume that constitute a notional three-dimensional space, especially each of an array of discrete elements into which a representation of a three-dimensional object is divided. Example sentencesExamples - Our sensitivity map demonstrates that in all voxels we had sufficient power to detect changes in gray matter fraction of 0.17 or less.
- The internal voxels were then discarded, leaving the object surface only.
- A small portion of the image surrounding one of the z lines, as indicated by the box in Fig.1 B, was magnified so that individual voxels could be seen.
- The values presented are the mean of nine voxels taken from the longitudinal images as shown in Figs 5 and 7.
- Thus, the signal from each image voxel is then proportional to the amount of blood that entered the voxel in the delay between the selective inversion pulse and the image acquisition.
- Greene has pointed out the computational advantages of operating in voxel space for quickly checking for obstructions as well as determining direct lighting.
- The mean number of water molecules contained in a definite volume is obtained by summing up the local density over all contributing voxels.
- The grid is made up of small cubes called ‘voxels,’ and each voxel has a specific address.
- The loss of lung tissue associated with emphysema can be measured as a reduction in lung density by CT, using various parameters derived from the frequency distribution histogram of lung voxels.
- The simulation box was divided into slices parallel to the xy plane and the atoms within these voxels were counted.
- In image reconstruction, the object is represented by a grid of pixels (picture elements) in two dimensions or voxels (volume elements) in three dimensions.
- The map demonstrates that, with our methods and subjects, changes in a voxel's gray matter fraction of 0.17 or less, depending on brain region, would have been detectable.
- The search engine works by converting stored CAD models and user-inputted sketches to voxels, the 3D equivalent of a pixel.
- A voxel (volume element) is defined as the individual picture element of a CT image, which has dimensions in the x and y plane, and includes the CT slice thickness as the third dimension (z axis).
