ABOMR study plan

Explain photon interactions (photoelectric, Compton, coherent) and predict how kVp and tissue atomic number shift the dominant interaction

Derive and apply the inverse square law and half-value layer to calculate exposure changes at varying distances and filtration

Distinguish deterministic (threshold) from stochastic radiation effects and state the dose thresholds for erythema, epilation, and cataractogenesis

Compare dose metrics (absorbed, equivalent, effective) and convert between units (Gy/Sv, rad/rem) in worked problems

Summarize radiation-induced carcinogenesis risk models and the basis for ALARA and dose-reference levels in dental imaging

Trace the intraoral image-formation chain from x-ray tube through receptor and identify where geometric and absorption unsharpness arise

Calculate magnification and describe how object-receptor distance and focal spot size govern spatial resolution

Compare intraoral receptor types (film, PSP, CMOS) on dose, dynamic range, and resolution

Sequence the steps of panoramic and cephalometric acquisition and predict the artifacts produced by patient positioning errors

Select exposure and technique factors for pediatric, edentulous, and gag-reflex patients and justify each adjustment

Describe digital processing operations (windowing, contrast/brightness, sharpening, noise reduction) and explain how each alters diagnostic yield without adding information

Design a quality-assurance schedule for intraoral and panoramic equipment including collimation, kVp, exposure reproducibility, and receptor uniformity tests

Interpret a rejected-image log and propose corrective actions that reduce repeat rate

Apply occupational and patient dose-reduction measures (collimation, shielding, selection criteria) to clinical scenarios

Explain the legal and recordkeeping requirements for equipment logs and dosimetry in a dental practice

Identify normal radiographic landmarks of the maxilla and mandible and distinguish them from pathologic findings

Map the anatomic spaces and foramina on panoramic and CBCT images and describe what each transmits

Classify developmental anomalies (cleft, dens invaginatus, taurodontism, supernumerary, fusion, concrescence) by their radiographic appearance

Differentiate radiolucent and radiopaque normal variants (e.g., mental foramen, submandibular fossa, torus) from disease in case-style vignettes

Correlate CBCT multiplanar anatomy with panoramic distortion to explain why a lesion appears in two locations

Build a differential-diagnosis framework for radiolucent jaw lesions organized by location, margin, and effect on adjacent structures

Compare odontogenic cysts and tumors (radicular, dentigerous, odontogenic keratocyst, ameloblastoma, odontoma, cemento-osseous lesions) on key imaging features

Distinguish non-odontogenic and fibro-osseous lesions and state which require biopsy versus imaging follow-up

Apply the border-margin and internal-structure descriptors used in lesion characterization to at least 10 written vignettes

Explain the limits of radiography for lesion diagnosis and when advanced imaging changes management

Recognize radiographic patterns of inflammatory bone disease (periapical, osteomyelitis, peri-implantitis) and their progression over time

Classify maxillofacial fractures by location and describe the radiographic projections or CBCT views that best demonstrate each

Identify signs of metabolic bone disease (hyperparathyroidism, Paget disease, osteoporosis) on dental and maxillofacial images

Differentiate osteoradionecrosis and medication-related osteonecrosis from routine infection using imaging and history

Sequence imaging decisions for trauma versus inflammatory presentations and justify each choice

Describe normal and abnormal TMJ imaging findings on panoramic, CBCT, and MRI and correlate them with clinical presentation

Compare imaging modalities for sialolithiasis, sialadenitis, and salivary gland masses and state the first-line choice for each

Identify soft-tissue calcifications (sialoliths, phleboliths, lymph nodes, carotid calcification) and state their clinical significance

Explain the role of ultrasound in head and neck soft-tissue evaluation and its limitations

Interpret written soft-tissue and TMJ vignettes and select the next best imaging study with justification

Compare CBCT, CT, MRI, ultrasound, and nuclear medicine on physical basis, dose, resolution, and clinical indications

Apply CBCT dose and field-of-view optimization principles and explain artifact sources (beam hardening, metal, motion)

Describe MRI weighting and contrast principles well enough to explain soft-tissue discrimination in the maxillofacial region

Apply ethical and professional standards: informed consent, appropriate use, referral, and documentation for imaging studies

Integrate all domains in a timed mixed-format practice set and analyze errors by domain
