 About Computed Tomography
Computed tomography, or CT scan, is an
advanced imaging modality that combines
the use of x-rays and computers to display a
cross-sectional picture of the body’s tissues
and organs.
The CT technologist performs the patient examination
under the supervision of the radiologist,
and has extensive knowledge of the capabilities
of the CT scanner, cross sectional anatomy and
basic pathology as it relates to CT. The CT technologist
may be required to administer contrast
injection and assist in interventional procedures.
The CT technologist supports quality patient care
and medical ethics. The patient and other members
of the health care team rely on the judgment,
skill and knowledge of the technologist as well as
his or her ability to operate the equipment safely
and efficiently.
Computed tomography has advanced so rapidly
that it is becoming the diagnostic tool of choice
for many non-invasive procedures, including
virtual colonoscopy and cardiac imaging.
