Radiological technologists operate X-ray, radiographic and fluoroscopic equipment, specialized CT scanners and mammography units to produce images of the body for use by radiologists in the diagnosis of disease or injury.

Nuclear medicine technologists operate radiation detection equipment such as gamma cameras, scanners, scintillation counters and ionization chambers to acquire information for use by nuclear medicine physicians in the diagnosis of disease.

Radiation therapists operate linear accelerators, and cobalt-60, X-ray and other radiation therapy equipment to administer radiation treatment prescribed by radiation oncologists.

Radiological technologists perform some or all of the following duties:

Operate X-ray, radiographic and fluoroscopic equipment, computerized tomography (CT) scanners, mammography units and magnetic resonance imaging (MRI) scanners to produce radiographs or anatomic images of the human body for the diagnosis by radiologists of disease or injury;

Record and process patient data;

Perform basic verification and quality control checks on radiographic and film processing equipment;

Provide appropriate care for the patient during the radiographic examination;

Apply radiation protection measures;

May train and supervise student radiographers or supervise other radiological technologists.

Radiological technologist may specialized in areas such as computerized tomography, angiography, mammography, magnetic resonance imaging, interventional radiology, dosimetry, stereotaxy or brachytherapy.
