CAMRT Radiation Therapy case studies
CAMRT Radiation Therapy · Put your knowledge to work in context.
The CAMRT Entry-to-Practice Certification Examination - Radiation Therapy is the certification exam pathway offered by the Canadian Association of Medical Radiation Technologists (CAMRT), which describes itself as Canada's national professional association and certifying body for medical radiation technologists and therapists across the country. CAMRT lists radiation therapy as one of the four disciplines represented among its membership, alongside radiological technology, magnetic resonance and nuclear medicine, so the radiation therapy certification route sits within a national framework that spans all four disciplines. The CAMRT Radiation Therapy case studies are 5 cases and about 2,058 words.
