static voxel

Gulce Esenturk
Hi,

I am not familiar with image J. Can anyone tell me what static voxel is and how I can calculate it?

Thanks in advance!!

Good day Gulce Esenturk,

not sure where you've found the term "static voxel" and how it may be
related to ImageJ.

What I'm able to tell you is, what "voxel" means:

A _voxel_ is a "volume element" (3D) which was derived from the term
_pixel_ that stands for "picture element" (2D).

In both cases it means a sample value, i.e. a _single_ number or, if
color is involved, a color spectrum or three color values in case of RGB.

Sample values (voxels) of 3D-objects are obtained by a discretization
process. Most often volume discretization is done by first selecting
consecutive planes and by applying 2D sampling to every plane. Usually,
the distance of the planes is called delta_z and the sampling distances
in every plane are called delta_x and delta_y. In many cases delta_x
equals delta_y.

It is important to understand that a voxel isn't a volume, but a number
(or a spectrum or an RGB number triple) located at a defined 3D _point_
location of an object. A volume can only defined by the three sampling
distances delta_x delta_y and delta_z.

Whether "static" has something to do with the temporal behavior of an
object, depends on the context that is apparently missing in your post.
