S: The History of Digital Imaging
FC: The History of Digital Imaging | By: Kimberly Kant & Myrna Garcia
1: Through the efforts of many scientists, digital imaging has evolved from just a few pixels which created a grainy radiographic image to electronic images that can be easily viewed, manipulated, and transmitted via the internet. This technology has greatly advanced the field of Radiologic Imaging.
2: The first generation of teleradiology began with Dr Albert Jutras' cable-mediated teleradiology program in Montreal, Canada | 1950's
3: Today, gateways securely send diagnostic images from the DICOM modalities and digitized film to designated off-site radiologists and other service providers using telecommunication infrastructure, usually the internet.
4: Godfrey Hounsfield | Implemented and was the first to use a CT scanner | 1970's
5: Allan Cormack | Shared the 1979 Nobel Prize with Godfrey Hounsfield for their work on the invention of the CT scanner.
6: First CT scanners only imaged the head | developed by Siemens
7: Axial CT image of a normal brain using a state-of-the-art CT system and a 512x512 matrix image | Original axial CT image from the dedicated Siretom CT scanner circa 1975
8: shared the nobel prize with Peter Mansfield in 2003 | Paul Christian Lauterbur | MRI
9: Sir Peter Mansfield | First to step inside the original whole body scanner
10: PACS | Development of PACS began in early to mid 1980's. These early PACS systems had little standardization in image formats
11: DICOM | The establishment of DICOM allowed imaging modalities and PACS to communicate in the same language
12: Early PACS was developed by US Military to move images from VA Hospitals and battlefield images to established hospitals
13: The first full scale PACS installed at the VA Medical Center in 1993
14: Computed Radiography | introduced commercially in the US in 1983
15: Digital Radiography | uses x-ray absorbing material or Charged Coupled Device to form images.
