pixel

 [pik´sel]
a picture element; a CT scan or PET scan is composed of an array of squares (pixels), each of which is colored a uniform shade of gray or another color. The corresponding region in the tissue slice that is imaged is called a voxel (volume element).

pix·el

(pik'sĕl),
A contraction for picture element, a two-dimensional representation of a volume element (voxel) in the display of the CT or MR image, usually 512 × 512 or 256 × 256 pixels, respectively.

pixel

A portmanteau for picture element, the smallest discrete two-dimensional unit of a digital image.

pix·el

(piks'ĕl)
A contraction for picture element, a two-dimensional representation of a volume element (voxel) in the display of the CT or MR image, usually 512 by 512 or 256 by 256 pixels respectively.

pix·el

(piks'ĕl)
Contraction for picture element, two-dimensional representation of a volume element (voxel) in the display of the computed tomographic or magnetic resonance image, usually 512 × 512 or 256 × 256 pixels, respectively.

pixel

a picture element such as a dot on a video display screen. The greater the concentration of pixels the clearer the image.
A CT scan or PET scan is composed of an array of squares (pixels), each of which is colored a uniform shade of gray or another color. The corresponding region in the tissue slice that is imaged is called a voxel (volume element). See also computed tomography.
