Integrated Department Workflow — Patient Care, QC, and Image Management

Objective. The student accurately executes full end-to-end radiographic workflow — from requisition review and patient assessment through image processing, PACS archiving, and equipment QC documentation — meeting department standards on every encounter.

⚠ Pending professional review

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.

Integrated Department Workflow — Patient Care, QC, and Image Management

A radiographic examination is not a single act — it is a chain of coordinated steps that begins the moment a requisition arrives and ends only when a verified, correctly labeled image is archived and available to the interpreting radiologist. Mastery of that entire chain, performed consistently and independently, is what the clinical practicum demands of you.

Requisition Review and Order Verification

Every encounter starts with the order. Before approaching the patient, read the requisition carefully. Confirm the clinical indication, the body part and projection(s) requested, and any special instructions (weight-bearing, post-reduction, portable). If anything is unclear or contradicts what you observe — for example, the order says left ankle but the patient points to the right — stop and clarify with the ordering provider before proceeding. Acting on an incorrect or ambiguous order is a preventable error.

Patient Identification and Assessment

The single most important safety step in the intake sequence is confirming two patient identifiers. Acceptable identifiers are defined by your facility's policy and typically include the patient's full name and date of birth, or name and medical record number. Never use room number or bed location as an identifier. Ask the patient to state the information — do not read it to them and ask for a nod.

After confirming identity, complete your clinical assessment before any exposure:

Explain the procedure in plain language, free of jargon. Obtain verbal consent and document it. A patient who understands what to expect is more cooperative, which directly improves image quality and reduces repeat exposures.

Image Processing and PACS Archiving

After acquisition, your responsibility shifts to image management. Before finalizing any series in the Picture Archiving and Communication System (PACS), verify every demographic field:

1. Patient name and medical record number match the order.

2. Date of birth is correct.

3. Body part label matches what was imaged.

4. Laterality markers (R/L) are present, correct, and visible within the image without obscuring anatomy.

A demographic error in PACS is not a minor clerical issue. A study archived under the wrong patient can lead to misdiagnosis, wrong-side surgery, or missed pathology. If you find an error, do not attempt an informal fix. Use the department's established correction protocol — this typically involves the PACS administrator and creates an auditable record. Document every correction in the clinical log with the date, nature of the error, and action taken.

Archive a minimum of 10 complete image series per week. Supervisor spot-checks will verify accuracy. Zero uncorrected demographic errors is the standard.

Equipment Quality Control

Quality control (QC) protects both patients and staff. Daily QC tasks assigned by your supervising technologist may include:

Record every result on the department QC log immediately — do not reconstruct entries from memory at the end of the shift. If any result is out of tolerance, remove the equipment from service and notify the radiologist or physicist in writing before resuming patient imaging on that unit. Verbal notification alone is insufficient; the written record protects the patient, the department, and you.

Dosimetry and Radiation Safety

Wear your personal dosimeter at the collar level, outside any lead apron, for every shift. Never leave it in a hot environment (car dashboard, windowsill) between shifts. Report any unexpectedly high reading to your supervisor immediately. Your dosimeter is the record of your occupational exposure — treat it as a professional document.

Clinical Documentation

Every patient encounter, QC task, and PACS correction must be documented in your clinical log on the day it occurs. The supervising technologist countersigns QC entries weekly. Incomplete or delayed documentation is treated the same as incomplete work: it does not exist in a regulatory or legal sense. Accurate, timely documentation demonstrates professional accountability and supports your credentialing portfolio.

Key terms9

Two patient identifiersTwo distinct pieces of information — such as full name and date of birth, or name and medical record number — used together to confirm a patient's identity before any procedure, per facility policy and accreditation standards.
PACS (Picture Archiving and Communication System)A digital network that acquires, stores, retrieves, and transmits medical images, allowing radiologists and clinicians to view studies from any authorized workstation.
RIS (Radiology Information System)A database system that manages patient scheduling, orders, and procedural records within a radiology department; often linked to PACS for worklist management.
Flat-field uniformity checkA daily QC test in which the detector is exposed without a phantom to identify artifacts, dead pixels, or areas of non-uniform response that could degrade diagnostic image quality.
Laterality markerA lead R or L marker placed in the primary beam during exposure to permanently indicate the right or left side of the body part imaged; must be visible without obscuring anatomy.
Demographic errorA mismatch between the patient's actual identity data and the information attached to an image study in PACS; requires correction through an official protocol to prevent diagnostic or surgical errors.
Penetrometer (step wedge)A QC test tool with graduated thicknesses of absorbing material used to evaluate a radiographic system's ability to reproduce a range of densities and contrast levels.
Out-of-tolerance findingA QC measurement that falls outside the acceptable range established by the manufacturer, the facility, or a regulatory body, requiring the equipment to be taken out of service until corrected.
Personal dosimeterA radiation-monitoring device worn by occupationally exposed workers to measure and record cumulative radiation dose; typically worn at collar level outside any lead apron.
In class: For every assigned patient encounter, complete the full intake sequence independently: verify order, confirm two patient identifiers, assess contraindications (pregnancy status, allergies, fall risk, mobility limitations), explain the procedure in plain language, obtain verbal consent, and document the interaction in the clinical log; the supervising technologist observes and rates patient communication on the standard evaluation form. · Perform and document daily equipment QC tasks assigned by the supervising technologist — including flat-field uniformity check, phantom or test-tool image review, and detector calibration verification — recording results on the department QC log and flagging any out-of-tolerance finding to the radiologist or physicist in writing. · Process and archive a minimum of 10 complete image series in PACS per week, verifying patient demographics, body part labels, and laterality markers before finalizing; correct any demographic error using the department's established correction protocol and document the correction in the log.
Materials: PACS workstation, RIS/order entry system, QC test tools (penetrometer, step wedge, or manufacturer-supplied phantom as available), department QC logs, clinical log, facility patient care policy manual, personal dosimeter
Check: Zero unresolved patient identification errors over the practicum period; QC log entries reviewed and countersigned by supervising technologist weekly; PACS archiving accuracy verified by supervisor spot-check — pass = no uncorrected demographic errors at month-end review

Practice check8

Answer each question, then check it. Nothing is recorded; this is your own practice.
