CAMRT Radiation Therapy study guide
CAMRT Radiation Therapy · Work through your exam, one topic at a time.
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 credential is intended for candidates at the entry-to-practice stage: CAMRT publishes separate certification guidance for graduates of Canadian accredited programs and for internationally educated medical radiation technologists, including an assessment process, language fluency requirements and bridging programs in Canada. Because the exam is competency-based, preparation should start from CAMRT's Entry-to-Practice Competency Profile and the published exam blueprints, which define what is tested and how it is weighted. The CAMRT Radiation Therapy study guide has 4 sections and about 1,161 words.
01Radiological Technology: Image Formation, Exposure Factors, and Quality Control
Radiological technology questions test whether you can trace a single exposure decision through the imaging chain. Know how the primary beam is shaped (collimation, beam-limiting devices), how differential attenuation produces subject contrast, and how the image receptor converts transmitted photons into signal.
332 words, about 2 min02Magnetic Resonance: Physics, Sequences, and Safety
Magnetic resonance questions reward a clear model of spin behavior in a magnetic field. Understand B0 field strength and homogeneity, precession and the Larmor equation (frequency proportional to field strength times the gyromagnetic ratio), and the RF excitation that tips magnetization into the transverse plane.
312 words, about 2 min03Nuclear Medicine: Radiopharmaceuticals, Imaging, and Radiation Safety
Nuclear medicine questions combine radiopharmacy, detector physics, and safety. Know that a radiopharmaceutical pairs a radionuclide with a biodistribution agent.
256 words, about 1 min04Radiation Therapy: Treatment Planning, Delivery, and Radiobiology
Radiation therapy questions test the link between prescription, planning, and delivery. Know absorbed dose units (gray), fractionation, and the therapeutic ratio.
