  • Information Technology and Digital Imaging: Pixel, Voxel, Hounsfield Unit (CT Number) – see Bushong [BUS1997:359, 386-387]:
    1. Pixel – picture element or a cell of information with position, brightness, and (if included) color data in a two-dimensional (2D) image matrix display; the storage space for each pixel must be adequate for positioning in the matrix and display qualities; in digital imaging, a 2D representation of tissue volume
    2. Voxelvolume element, which amounts to pixel size extended by CT scan slice thickness
    3. Hounsfield Unit – a standardized numerical value for pixel brightness for CT scanning
