Allied health professional in the context of "Scope of practice"

A radiation therapist, therapeutic radiographer or radiotherapist is an allied health professional who works in the field of radiation oncology. Radiation therapists plan and administer radiation treatments to cancer patients in most Western countries including the United Kingdom, Australia, most European countries, and Canada, where the minimum education requirement is often a baccalaureate degree or postgraduate degrees in radiation therapy. Radiation therapists (with master's and doctoral degrees) can also prescribe medications and radiation, interpret tests results, perform follow ups, reviews, and provide consultations to cancer patients in the United Kingdom and Ontario, Canada (possibly in Australia and New Zealand in the future as well).In the United States, radiation therapists have a lower educational requirement (at least an associate degree of art, though many graduate with a bachelor's degree) and often require postgraduate education and certification (CMD, certified medical dosimetrist) in order to plan treatments.

A medical assistant, also known as a "clinical assistant" or healthcare assistant in the US, is an allied health professional who supports the work of physicians, nurse practitioners, physician assistants and other health professionals, usually in a clinic setting. Medical assistants canbecome certified through an accredited program. Medical assistants perform routine tasks and procedures in a medical clinic.

A "medical assistant" may be certified or registered, or may be a loosely defined group (covering related occupational titles such as "medical office assistant", "clinical assistant", "assistant medical officer", or "ophthalmic assistant"). The occupation should not be confused with physician assistants, who are licensed professionals trained to practice medicine and perform surgical procedures in collaboration with a physician.
