Radiological Technologists


Radiological technologists use equipment that produces radiation to obtain images, such as chest x-rays, back x-rays, CT scans, and mammograms. These images (or x-rays) of a body part or system help the physician make a diagnosis.

Radiological technologists use their excellent patient care skills and expert knowledge of anatomy and pathology to monitor and correctly position the patient. They utilize their technical expertise to operate the equipment properly, and ensure radiation protection methods are followed, in order to protect all staff and visitors.

Radiological Technologists known by many as x-ray technologists, make up about 75% of the 2,000 members of the ACMDTT. Radiological technologists produce structural images of the body for diagnostic purposes. They may be involved with a broad variety of general and specialized procedures and areas including:

  • plain film radiography: x-rays of your chest, bones, joints, and spine
  • gastrointestinal fluoroscopy studies: images of your gastrointestinal or GI system, the area between your throat and your rectum
  • mammography: special images of your breasts to find breast cancer at the earliest stages
  • angiography: specialized test to look at your blood vessels (arteries and veins), also for the blood supply to your limbs (arms and legs) and major organs like the heart and brain
  • computerized tomography or CT scans: test that gives cross-sectional images of parts of your body

The Alberta College of Medical Diagnostic and Therapeutic Technologists (ACMDTT) has adopted the Canadian Association of Medical Radiation Technologists’ (CAMRT) competency profiles for the medical radiation technology specialties that it regulates. Previous competency profiles for these specialties have been rescinded. The ACMDTT acknowledges that CAMRT’s profiles reflect current practice in Alberta.
