voxelsize
Voxel size is a basic property of 3D image data that describes the physical edge length of a voxel, the smallest unit in a three-dimensional grid. It is typically expressed as a three‑value vector [dx, dy, dz], with units such as millimeters or micrometers. If dx = dy = dz, the voxels are isotropic; otherwise they are anisotropic, which is common when in-plane resolution differs from slice thickness.
Voxel size is determined by acquisition and reconstruction parameters. In medical imaging, it depends on factors
Voxel size matters for quantitative analysis. Volumes and surfaces are computed from voxel counts via the voxel
Metadata and formats: voxel size is stored in image metadata. DICOM represents this as Pixel Spacing and
Common considerations include avoiding the assumption of isotropy, accounting for partial volume effects, and distinguishing voxel
