Radiological technology is the production of images of internal organs and structures by passing a small, highly controlled amount of radiation through the human body, and capturing the resulting image on an image recording device. When x-rays penetrate the body, they are absorbed in varying amounts by different parts of the anatomy. Bones, for example, will absorb much of the radiation and, therefore, appear white or light gray on the image, whereas soft tissue absorbs little radiation and appears dark.

Contrast agents are sometimes used to enhance certain organs and structures that otherwise are not visualized on a radiographic image. The exposed imaging plate is either placed in a developing machine, producing images much like the negatives from a 35-mm camera, or is digitally captured and stored on a computer.

The field of radiological technology also includes therapeutic procedures, often referred to as interventional radiology. Interventional Radiology is used in the detection, diagnosis and treatment of injury and disease.

Some Examples of Radiography:

• Plain film radiography is used to detect bone fractures and pathological processes, locate foreign objects in the body, and demonstrate the relationship between bone and soft tissue.
• Mammography produces radiographic images of the breast to detect cancer in its earliest stages
• Angiography uses contrast agents to examine the heart and blood vessels
• Fluoroscopy produces real-time images that show movement of material (contrast agents) through blood vessels or ducts; fluoroscopy is also used in orthopedic procedures,such as hip and knee surgery, to enable the surgeon to visualize the bony anatomy of interest in relation to surgical devices/hardware
• Computerized Tomography produces cross-sectional, 3-dimensional images of the body

What does a Radiological Technologist do?

• Radiological Technologists play an integral role in the detection of injury and disease; they are the medical personnel who perform diagnostic imaging examinations, including mammography and computerized tomography.
• Radiation Technologist are detail-oriented and enjoy applying their knowledge of anatomy, physiology, and mathematics; Radiological Technologists are responsible for accurately positioning patients and ensuring that a quality diagnostic image is produced.
• Radiological Technologists work closely with patients, doctors, and other health professionals as part of the interdisciplinary health care team.
• Radiological Technologists use cutting-edge medical imaging technology and advanced computer systems to produce and enhance radiographic images.
• Radiological technology uses advanced computerized equipment to perform complex anatomical scans, many in real-time!

Why become a Radiological Technologist?

Radiological technology offers many areas of specialization

• mammography (breast imaging)
• computed tomography (CT)
• diagnostic visceral and peripheral angiography with interventional radiology
• electronic image management (PACS)
• neuroradiology or trauma radiography

Radiological Technologists are vital members of the interprofessional health care team devoted to patient care. Technologists must have the technical expertise to operate sophisticated instruments, but must also have the humanistic skills necessary to communicate with patients, problem-solve, and work well with other members of the health care team.

The joint University of Toronto/Michener Radiological Technology Degree/Advanced Diploma program is a three-year full time program. There is one intake each year, in September, and courses are held at both UofT’s downtown campus and at Michener.

Graduates earn a BSc in Medical Radiation Sciences from the University of Toronto and a Diploma in Radiological Technology from The Michener Institute and may pursue advanced studies at Michener, including:

• Magnetic Resonance Imaging (MRI)
• PACS Administrator
• Master of Health Science in Medical Radiation Sciences
• Master of Applied Science (Medical Imaging)
