Fluoroscopy

Fluoroscopy

an imaging technique that uses X-

ray beam to produce real-time,

moving images of the interior of a

patient's body, similar to an X-ray

"movie"

Vitascope

old name of fluoroscope

Enrico Salvioni

He invented the Cryptoscope, one of the

first real-time imaging device used to

view internal body structures. He used

Barium platinocyanide as fluorescent

screen.

William Francis Magie

Another device for direct viewing of real-

time body structure using Barium

platinocyanide as fluorescent screen. It is

called Skiascope or 'shadow perceived'

Thomas Alva Edison

He found calcium tungstate effective at

re-emitting x-ray as visible light. He was

able to develop the live imaging device

named Vitascope and later commercial-

ized and coined the term Fluoroscope.

Clarence Dally

Edison's ‘mucker' (laboratory assistant).

He would spend hours exposing

himself to dangerous radiation as part of

experimentation. Eventually, he lost his

life due to x-ray overexposure.

Wilhelm Trendelenburg

He invented the Red adaptation goggles.

Worn by physician prior to a fluoroscopic

procedure as a way to dark adapt the

eyes while still being able to see well

enough to function.

John Coltman

was credited for inventing the first image

intensifier tube. This invention

revolutionized dark room concepts by

producing bright, visible images, and

reducing radiation exposure to staff.

Conventional Fluoroscopy

X-ray source → Patient →

Image Intensifier (x-ray →

light photons → electron →

intensified light) → Video

Camera → Monitor Display

Digital Fluoroscopy

X-ray source → Patient → Flat

Panel Detector (FPD)/Image

Intensifier (II) → Analog-

Digital Converter (ADC) →

Digital Computer → Monitor
