Radiologic Technologist

Working under the direction of radiologists, radiologic technologists, also called medical radiation technologists or radiographers, take X-rays (radiographs), which are images of the inside of the human body. Experienced radiographers may perform more complex imaging procedures, such as computed tomography (CT) or magnetic resonance imaging (MRI) scans. Radiologic technologists work in hospitals, clinics, medical laboratories and private practice.

To prevent unnecessary exposure to radiation, radiation technologists surround the exposed area with radiation protection devices, such as lead shields, or limit the size of the x-ray beam. Radiographers position radiographic equipment at the correct angle and height over the appropriate area of a patient’s body. They must follow physicians’ orders precisely and conform to regulations concerning the use of radiation to protect themselves, their patients, and their coworkers from unnecessary exposure.

The allied health field known as radiologic technology has its own sub-specialties, including:

  • Diagnostic radiography
  • Sonography
  • Fluoroscopy
  • CT (computed tomography)
  • MRI (magnetic resonance imaging)
  • Nuclear medicine
  • Radiotherapy
  • Mammography
