FLUOROSCOPY
Fluoroscopy is a method of obtaining radiological image in a fluorescent screen or phosphor.
This imaging procedure gives live X-ray viewing of the patient. It is used to obtain real-time
moving images of the internal structures of a patient through the use of a fluoroscope.
This requires 30 frames per second, as in television technology. This will facilitate to
follow motion of an organ, over a period of time.
INDICATIONS:
Used in a variety of procedures
Orthopedic surgery
Observe fractures and healing bones
Catheter insertion
Direct catheter placement
(Angiography / Angioplasty)
Barium X-rays
Observe movement through GI tract
Blood Flow studies
View blood flow to organs
Injections into the knees
Viscosupplementation injections
Locating foreign bodies
Percutaneous vertebroplasty
Treating compressed fractures of the spine
Injections into joints or spine
, Image guided anesthetic injections

Fluoroscopy is divided into
Direct vision fluoroscopy
Image intensifier fluoroscopy
Flat panel fluoroscopy
DIRECT VISION FLUOROSCOPY:
In direct vision fluoroscopy, the X-rays that are transmitted through the patient are
passed on to a scintillation phosphor screen, which gives an image as faint scintillations. The
radiologists used to view the image directly with red goggles in a dark room. The thick
phosphor converts the X-rays into light proportionally, but the brightness is low.
Disadvantages:
1) The light output of the fluorescent screen is very poor
2) Patient will receive High radiation dose.
3) The contrast and spatial resolution is very low.
IMAGE INTENSIFIER FLUOROSCOPY:
Modern systems use image intensifiers and a closed circuit TV system. The
transmitted radiation is made to fall on a phosphor through a image intensifier. A collimator
limits the size of the X-ray beam automatically to the proper field of view. As a result, a
