ABR TMP study plan

Reconstruct the photon dose-calculation chain end to end: CT number to electron density conversion, beam commissioning data, and the path from percent depth dose and tissue-air ratio to absorbed dose.

Solve by hand at least six monitor-unit and dose problems covering SSD and SAD setups, inverse-square corrections, tray and wedge factors, and field-size output factors.

Derive and interpret plan-evaluation metrics (D95, D2, V20, conformity index, homogeneity index) and state the clinical failure mode each one is designed to catch.

Build a one-page equation sheet from memory, then verify every entry against your references and mark each correction in a different color.

Compare 3DCRT, IMRT, VMAT, and SBRT plans for the same hypothetical target and justify the chosen technique using dose-gradient, integral-dose, and treatment-time arguments.

Evaluate a written DVH summary for a target and two organs at risk, and write the specific replan or accept recommendation with the tradeoff quantified.

Explain how heterogeneity correction, grid size, and calculation algorithm choice shift calculated dose, and predict the direction of the shift in a lung-like geometry.

Draft the acceptance criteria you would apply to a patient-specific IMRT QA measurement and state which failures trigger a plan review versus a measurement repeat.

Reconstruct the reference-dosimetry calibration chain from ion chamber reading to stated machine output, including temperature-pressure and electrometer corrections, and compute output for one changed condition.

Reproduce from memory the daily, monthly, and annual QA tests for a linear accelerator with their tolerances, then flag every item you could not recall and close those gaps.

Diagnose three written fault scenarios (output drift, MLC position error, flatness change) by naming the confirming measurement and the corrective action sequence.

Sequence an end-to-end IGRT workflow from simulation to treatment, stating the action taken at each matching threshold and who authorizes it.

Calculate source strength conversions and decay corrections for iridium-192, iodine-125, and palladium-103 high- and low-dose-rate sources, working from stated half-lives.

Apply the TG-43 formalism by hand to compute dose at a point from a single source with anisotropy and radial dose function values supplied in the problem, and state each assumption.

Compare HDR, PDR, and LDR approaches on fractionation, radiobiology, shielding, and workflow, and select the appropriate modality for two contrasting case vignettes.

Outline the response to a source dislodgement or stuck-source event, naming the survey, documentation, and notification steps in order.

Interpret implant quality metrics (D90, V100, V150, dose to organs at risk) for a prostate and a gynecologic implant and state the corrective action for each under-covered case.

Trace the brachytherapy workflow from applicator insertion through imaging, planning, treatment, and source removal, listing the verification checkpoint at each transition.

Explain how applicator reconstruction uncertainty and imaging modality choice propagate into reported dose for gynecologic implants.

Audit a written brachytherapy plan against a checklist you construct, and document every discrepancy found.

Compare CT simulation, kV and MV cone-beam CT, ultrasound, and MRI on contrast, spatial accuracy, artifacts, and dose, and match each to the clinical question it answers best.

Quantify image-quality tradeoffs by explaining how mAs, kVp, slice thickness, and reconstruction kernel change noise, contrast, and geometric fidelity.

Evaluate rigid versus deformable registration output for a written case and state when deformable registration must not be used for dose accumulation.

Integrate image guidance into a brachytherapy and an SBRT scenario, specifying the registration method, tolerance, and escalation path for each.

Compute primary and secondary barrier transmission for one treatment room using stated workload, use factor, occupancy factor, and distance, and compare the result to the required limit.

Apply ALARA and dose-limitation principles to a written scenario involving a pregnant worker or a member of the public, and state the recommended action with the governing limit cited.

Trace a DICOM image set and RT plan through the informatics chain from scanner to treatment record and verify, identifying where a mismatch could cause a wrong-site or wrong-dose error.

Explain the reporting obligations and root-cause process following a written near-miss, and distinguish an error from a violation.

Synthesize professionalism content - informed consent, peer review, scope of practice, and conflict-of-interest disclosure - into answers for four written vignettes.

Complete a timed full-length mock examination under test conditions and score it by domain to identify residual weak areas.

Re-derive every formula on your equation sheet from memory and reconcile any drift against your corrected version.

Build a prioritized remediation list for the final days, ordered by expected score gain per hour of study.
