2D scanners are commonly used to convert paper documents into electronic form by scanning images. They are often used at airports to scan documents. 3D scanners scan solid objects and produce three-dimensional images by taking images along the x, y, and z coordinates. Computed tomography (CT) scanners are a type of 3D scanner that uses tomography technology to build up a 3D image of a solid object by creating a series of very thin slices.

THE MOST COMMON FORM AND
ARE GENERALLY USED TO INPUT
HARD COPY (PAPER) DOCUMENTS.
THE IMAGE IS CONVERTED INTO
AN ELECTRONIC FORM THAT CAN
BE STORED IN A COMPUTER.

• 3D SCANNERS SCAN SOLID OBJECTS
AND PRODUCE A THREE-DIMENSIONAL
IMAGE. SINCE SOLID OBJECTS HAVE X,Y
AND Z COORDINATES, THESE SCANNERS
TAKE IMAGES AT SEVERAL POINTS
ALONG THESE THREE COORDINATES. A
DIGITAL IMAGE WHICH REPRESENTS
THE SOLID OBJECT IS FORMED.

• Computed tomographic (CT) scanners are
used to create a 3D image of a solid object.
This is based on tomography technology,
which basically builds up an image of the
solid object through a series of very thin
'slices'. Each of these 2D 'slices' make up a
representation of the 3D solid object.
