CAMRT RTR Exam study plan

Map Domain 1 into a one-page topic tree covering radiation physics, image acquisition and production, equipment, positioning/procedures, and patient care

Derive the relationships among mAs, kVp, distance, and receptor exposure, and predict how each change shifts brightness and contrast

Solve 10 inverse-square-law and attenuation problems showing each step

Reconstruct the skull, facial bones, and major long-bone landmarks from memory on blank outlines

Answer 25 positioning and projection questions by reasoning from anatomy rather than memorized protocols

Diagram the MR system components (main magnet, shim coils, gradients, RF chain) and state the function and failure mode of each

Contrast T1, T2, and proton-density weighting by predicting signal from given TR/TE values

Rank common radiographic and MR safety hazards by severity and state the control for each

Trace k-space filling and explain how it governs contrast, resolution, and scan time

Explain how flip angle, TR, and TE interact to change tissue contrast in gradient-echo imaging

Identify 8 artifacts from written descriptions only (no images) and prescribe the correction for each

Summarize gadolinium safety, SAR limits, and implant screening rules into a checklist

Compare MR signal generation with radiotracer decay and detection in a two-column written analysis

Explain radionuclide production routes and match 8 common radiopharmaceuticals to their clinical study and normal biodistribution

Solve 10 half-life and decay-factor problems to within 5% of the correct value

Differentiate gamma camera components and collimator choice by energy and resolution requirement

Explain photopeak, energy window, and scatter correction and predict the effect of a mis-set window

Compare static, dynamic, SPECT, and whole-body acquisition modes by indication and processing steps

Apply ALARA to three worked scenarios involving dose limits, shielding, and contamination control

Recite the regulatory and handling rules for receiving, storing, and disposing of radioactive material

Sequence the radiotherapy workflow from simulation through planning, delivery, and verification, annotating decision points

Compare photon and electron interactions with tissue and explain how each shapes dose distribution

Interpret percent depth dose, isodose curves, and DVH summaries for a stated plan

Calculate 8 simple dose, fractionation, and treatment-time problems

Differentiate external beam, brachytherapy, and systemic therapy by physics, delivery, and safety requirements

List tolerance doses for at least 8 organs at risk and explain the clinical consequence of exceeding each

Explain machine and plan QA, imaging-on-rails, immobilization, and set-up error sources and their corrections

Describe the roles and responsibilities of each member of the treatment team

Sit two full-length timed mocks under exam conditions with no references open

Reconcile every error-log entry by rewriting the 20 most-missed concepts as one-line decision rules

Recite the top 10 safety, regulatory, and dose-limit facts for each of the four domains from memory

Rehearse exam-day logistics, timing strategy, and flag-and-return rules for question blocks
