Objective. Students execute a complete radiographic patient episode — from order review through image submission — without instructor prompting, meeting entry-level competency standards across positioning, technique, radiation protection, image critique, and documentation.
This lesson, its worked examples and its practice questions has not yet been verified by a licensed clinician in the field or by a certification or approval body. It is a study draft and may contain errors. Do not use it to make decisions about any patient or medication. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
Every radiographic examination you perform is more than a technical task. It is a continuous chain of decisions — reviewing the order, greeting the patient, positioning, selecting technique, exposing, processing, critiquing, and documenting — and every link must hold. Entry-level competency means you can complete that entire chain independently, without coaching, for any examination type within your scope. This lesson brings together every skill you have built and asks you to execute them as one seamless act of patient care.
Before you touch the equipment or greet the patient, read the order carefully. Confirm the examination type, the body part, any relevant clinical indication, and the ordering provider. Check that the correct patient name and date of birth appear in the imaging system. Order review is your first safety checkpoint — it catches wrong-patient and wrong-exam errors before they reach the room. If anything on the order is unclear or contradicts what the patient tells you, stop and clarify with the ordering provider. Never proceed on an ambiguous order.
Introduce yourself, state your role, and confirm the patient's identity using at least two identifiers (typically name and date of birth). Explain what will happen in plain language. Take a brief history relevant to the examination: prior surgery, implants, possibility of pregnancy in patients of reproductive age, and ability to cooperate with positioning. Ask the patient to remove all metallic objects in the field — jewelry, snaps, zippers, belts — and document that you did. Failure to remove metallic objects is a critical error because artifacts obscure anatomy and can require a repeat exposure, adding unnecessary dose.
Apply gonadal shielding to all patients of reproductive potential unless the shield will obscure essential anatomy. Shield the thyroid and lens of the eye when those structures are near the primary beam. Collimate to the area of clinical interest — tight collimation reduces scatter, improves image contrast, and limits patient dose. These are not optional courtesies; they are professional and ethical obligations. An unshielded gonad on a reproductive-age patient is a critical safety failure that requires an automatic repeat of the encounter in this program's competency evaluation.
Position the patient precisely: align the part to the image receptor, apply the correct central ray angle and direction, use the appropriate source-to-image receptor distance (SID), and place lead markers (R or L, as appropriate) in the correct corner before exposure. Consult your technique chart if needed — that is professional practice, not weakness. Select kVp and mAs appropriate for the part thickness and clinical goal. For digital systems, monitor your Deviation Index (DI) or Exposure Index (EI) after the exposure; values outside the acceptable range signal an under- or over-exposed detector and should trigger a technique correction before the image is sent to the radiologist.
Before you submit any image, evaluate it yourself. Ask: Is the correct anatomy included? Is positioning accurate — are the proper joints open, are the correct structures in profile, is there rotation where there should be none? Is the exposure indicator within target range? Is collimation visible and appropriate? Are markers present and legible? Is there any motion blur? This self-critique step is not bureaucratic; it is your last chance to catch an error that would require a repeat exposure and delay patient care. Document every deviation you find, explain why it occurred, and state what you would do differently.
Complete all required documentation in the PACS or RIS simulation: patient identifiers, examination type, exposure factors, any patient care notes, and your technologist identifier. Submit the images to the correct patient folder. Errors in documentation can cause images to be filed under the wrong patient, with serious consequences for diagnosis and patient safety.
After each simulated encounter, compare your images against the positioning checklist systematically — do not rely on general impressions. Use the competency rubric as a shared language when giving peer feedback: be specific, cite criteria, and focus on the image and the process, not the person. Hearing feedback is a professional skill; receive it without defensiveness and use it to adjust your next encounter.
You will independently perform two randomly assigned examinations — one thoracic/abdominal and one musculoskeletal. No instructor prompting is permitted. You will be evaluated from the moment you review the order through image submission. You must score 80% or higher on each examination using the comprehensive competency rubric. Any single critical safety error — unshielded gonads in a reproductive-age patient, failure to verify patient identity, or failure to remove metallic objects from the field — results in an automatic repeat of that encounter. Passing this examination signals that you are ready to perform at entry level under supervision in a clinical setting.
Answer each question, then check it. Nothing is recorded; this is your own practice.
