OCCUPATIONAL SUMMARY
(Reference: THE
HEALTH PROFESSIONS by Boyles, Morgan and McCaulley)
Radiologist: A doctor
of medicine or osteopathy who specializes in the use of x-rays and other
ionizing and non ionizing radiation in the diagnosis and treatment of disease.
Radiologic Technologist: A generic term
encompassing technically trained persons specializing in radiography, radiation
therapy, and/or nuclear medicine who work under the direction of a physician
qualified to order and perform radiologic procedures.
Radiographer (Diagnostic
Radiographic Technologist, X-ray Technologist): A technically trained
person who, under the supervision of a radiologist, maintains and safely uses
equipment and supplies necessary to demonstrate portions of the human body on
x-ray film, computers or fluoroscopic screens for diagnostic purposes.
Radiation Therapy
Technologist or Radiation Therapist: A radiologic
technologist who assists physicians in the treatment of diseases, such as
certain types of cancer, by administering prescribed doses of radiation to the
affected areas of the body.
Nuclear Medicine
Technologist: A technically prepared individual who performs a variety of
diagnostic tests and some therapeutic procedures using radioactive compounds in
pharmaceutical form.
INTRODUCTION: Radiologic technologists are health professionals whose
broad interests and capabilities encompass the use of ionizing and non-ionizing
radiation, particularly x-rays and radionuclides, in
diagnosis and therapy. Within this general category are radiographers,
radiation therapy technologists, and nuclear medicine technologists.
Radiographers make up the
largest group. Their principal duties consist of performing x-ray
examinations of patients under the direction of a doctor of medicine,
osteopathy, or veterinary science, usually a radiologist, whom they also assist
in fluoroscopic examinations and in special radiographic procedures, some of
which are quite complex. Most of these technologists are employed in
hospitals, clinics, and physicians' offices.
The second group, the radiation therapy technologists, assist the
therapeutic radiologists in the treatment of patients usually in health centers
involved in the management of patients afflicted with cancer.
The third group consists of
nuclear medicine technologists, who administer radiopharmaceuticals to perform
diagnostic imaging and laboratory examinations.
RADIOGRAPHERS: Tasks performed by
radiographers vary. The radiographer must know how to perform all types
of x-ray examinations and must also be able to handle seriously ill and injured
patients. They must obtain the maximum amount of image information
without injury to the patient and with the least amount of pain and discomfort
from the examination. The radiographer, who assists the radiologist or
other specialist in some of the complex procedures, often involving the
injection of opaque media through needles or catheters, must be well trained
and experienced in aseptic techniques, requiring skills often comparable to
those of nurses in some specialties.
The radiographer in the
hospital or office works on patients in radiographic-fluoroscopic rooms and
frequently has other duties, such as film procession, checking and filing of
radiographs (exposed x-ray films) and other responsibilities, depending on the
size and nature of the department. Most are employed for a 40-hour week,
but since emergencies occur at any time of day or night, radiographers may also
be on call for night, weekend, and holiday coverage. When such is the case,
compensatory time off or additional financial compensation is usually allowed.
Large departments often employ radiographers just for this type of coverage.
Special imaging procedures,
which encompass many types of examinations, are challenging to enterprising
radiographers who wish to develop special skills. In larger hospital
departments such radiographers often devote the major portion of their time to
assisting radiologists and other specialists in procedures, such as vascular
catheterization, myelography (spinal canal studies),
and cerebral angiography (brain studies). The development of computed
axial tomography (CAT scanning) magnetic resonance imaging (MRI) and other
advanced techniques such as thermography, xerography,
and the use of ultrasound, have brought about a corresponding need for
radiographers in these areas, even though all do not involve ionizing
radiation.
