flouroscopy

1. • Fluoroscopy is a radiologic technique used to examine
the body or an organ.
• It uses X-rays for this purpose.
• While the X-ray machine is able to take one picture at a
time, fluoroscopes are able to take multiple shots per
second to show it as a moving

• Fluoroscopes are used mainly for organs because they
do involuntary work. Bones do not do anything unless
they are commanded.
• Because of this, fluoroscopes are used to check if the
organ(s) is(are) functioning properly.

• The main part that differs a fluoroscope from an X-ray
machine
is an Image Intensifier.
• Image Intensifiers are used to amplify low light level
images in a wide wavelength range to observable
levels.
• Since X-ray photons are not visible, they are sent to
image
intensifiers.
• This work is done by
input phosphor.
• Photocathode respond
to light stimulation with
emission of electrons,
process called
photoemission.

4. • Fluoroscopy is used in many types of
examinations and
procedures:
• Barium X-rays
• Cardiac catheterization
• Arthrography (visualization of a joint or joints)
• Lumbar puncture
• Placement of intravenous (IV) catheters
(hollow tubes inserted into veins or arteries)
• Biopsies
