Technical workers are trained to operate scanning and imaging equipment that is used to confirm what is happening with patients and health problems. The technical workforce is diverse with at least 20 occupational groups ranging from anaesthetic technicians to medical physicists and radiation therapists. Technical workers often work in relative isolation from each other.

Medical Training

A medical technician can work in a diverse number fields, and often takes certification or training courses in a specialized field after completion of high school. The term medical technical can apply to people who work in x-ray labs, pharmacy and veterinary assistants, and a plethora of other work environments.

Medical Imaging

Medical imaging refers to the techniques and processes used to create images of the human body for clinical purposes or medical science (including the study of normal anatomy and physiology).

As a discipline and in its widest sense, it is part of biological imaging and incorporates radiology, radiological sciences, endoscopy, thermography, medical photography and microscopy e.g. for human pathological investigations.
