Ultrasound; Nuclear Medicine - Kodak dryview 8300 User Manual

User Guide
C-ARMs are typically used in surgery and emergency rooms outside of radiology.
Typical surgery uses are during orthopedic procedures for checking pin placements
and joint orientations, and for neuro procedures for guiding to tumors.
A version of C-ARMs is used in urology for prostate and/or bladder surgery. The
urology system differs from a standard C-ARM very little. A different table
configuration exists with stirrups and surgeon seating areas. Various software
differences are also present.

Ultrasound

The Ultrasound system produces images using high-frequency sound waves. When
these sound waves come into contact with structures within the body, part of the
sound energy is reflected back to the body surface where it is converted
electronically into a picture. This technique is commonly used during pregnancy to
determine if multiple fetuses are present or the position and age of a fetus.
An echocardiogram is a useful ultrasonic technique to examine patients with
congenital or acquired heart conditions, and the Doppler ultrasound detects blood
flow in the veins and arteries in the body.
Work is usually performed by radiologists or medical specialists for diagnostic
purposes in hospitals and imaging centers.

Nuclear Medicine

The use of isotopic or radioactive tracers to diagnose or treat disease is the branch
of radiology known as nuclear medicine. Tiny amounts of compounds "tagged" with
radioactive isotopes are introduced into the body either orally or by injection into a
vein. These substances travel through the bloodstream to the specific organ or type
of tissue being evaluated. The radiation released by the isotopes is detected by
devices called scintillation cameras. Computers convert the data from these
cameras to images that allow visualization of parts of organs not usually seen by
normal X-rays.
By tracking how and where the radioactive compounds travel, the nuclear medicine
physician is able to gain information about biological processes, such as in a heart
scan which determines if any areas of the heart are not receiving sufficient amounts
of blood. Also, a therapeutic dose of radiation can be delivered to a specific organ
for treatment, for example, radioactive iodine for thyroid disorders.
Another type of Nuclear Medicine is the Conventional system which uses gamma
camera without computers to create images from injection of radio-isotopes in a
static fashion.
