The first scanner to store its images digitally onto a computer was a drum scanner built in 1957 at the National Bureau of Standards (NBS, later NIST) by a team led by Russell A. Kirsch. It used a photomultiplier tube to detect light at a given point and produced an amplified signal that a computer could read and store into memory.
A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists. [3][4]

Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene photo (for example the text on signs and ...

A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. [1] Like a flatbed scanner, it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals. Additionally, nearly all barcode readers contain decoder circuitry ...
The DEC PDP11/34 computer played a pivotal role in the operation of the ACTA and 200FS scanners. It controlled the gantry, managed the scanning process, and processed raw data into the final images. Remarkably, this computer functioned with a mere 64 KB of memory and a 5 MB hard disk, which held both the operating program and the acquired raw data.
Scanography (also spelled scannography), more commonly referred to as scanner photography, is the process of capturing digitized images of objects for the purpose of creating printable art using a flatbed "photo" scanner with a CCD (charge-coupled device) array capturing device. Fine art scanography differs from traditional document scanning by ...
