A History of Fluoroscopy Systems - The Evolution of Medical Imaging Technology

The development of X-ray image intensifiers

A Brief History of Fluoroscopy Systems:

The xray photons struck the fluoroscopic screen – emitting light

Direct Fluoroscopy: radiologist stands behind the screen and views the picture

Stages in the Development of Flouroscopy:

‘Photomultipliers, which enable visualization of weak photons to improve diagnostic radiology, were invented in 1955. Since 1961, remotely operated X-ray fluoroscopy has been developed; this was followed by widespread clinical application of the image intensifier (I.I.) system for analog fluoroscopy in the 1980s. Ten years after, fluoroscopy was further enhanced by image intensifier digital radiography (IIDR), which began to be utilized in the clinics in the 1990s.’

The development of image intensifiers:
The red adaptation goggles became obsolete as image intensifiers allowed the light produced by the fluorescent screen to be amplified, allowing it to be seen even in a lighted room.

The development of the television camera:
The addition of the camera enabled viewing of the image on a monitor, allowing a radiologist to view the images in a separate room away from the risk of radiation exposure.

Modern improvements in screen phosphors

Development of flat panel detectors

Use of CsI screens:
Modern fluoroscopes use CsI screens and produce noise-limited images, ensuring that the minimal radiation dose results while still obtaining images of acceptable quality.

1898: The inappropriate, nonmedical use of fluoroscopy becomes increasingly common.

1900: Radiation injuries become increasingly common, and practitione
1929: The National Council on Radiation Protection and Measurement (NCRP) is created to protect patients, healthcare workers, and the public from the harmful effects of radiation.

Pioneers in the Development of Fluoroscopy:

1896: Thomas Edison invents the first fluoroscope, which is quickly adopted for medical uses.

rs become increasingly aware of the dangers of x-ray exposure.
1910: After several years of practice, radiology pioneer Dr. Mihran Kassabian suffers severe radiation burns to his hands and ultimately dies of radiation-induced cancer at age 34.
