Standard Operating Procedure: X-Ray Room Operations and Safety

This Standard Operating Procedure (SOP) outlines the mandatory protocols for the safe and efficient operation of the X-Ray examination suite. As ionizing radiation presents significant health risks, adherence to this document is non-negotiable for all personnel. This SOP ensures compliance with regulatory radiation safety standards (ALARA—As Low As Reasonably Achievable), protects equipment integrity, and ensures optimal diagnostic image quality for patient care.

Pre-Operational Inspection & Safety Checks

• Radiation Safety Badge: Ensure all staff members are wearing their assigned dosimeter badge at chest level outside of any lead shielding.
• Warning Signage: Verify that the "X-RAY IN USE" illuminated sign is functional and visible above the room entrance.
• Equipment Integrity: Inspect the X-ray tube housing, cables, and collimator for visible damage or frayed wires.
• Emergency Stop: Locate the emergency kill switch and ensure the path to it is unobstructed.
• Lead Apparel Check: Inspect all lead aprons, thyroid collars, and gonadal shields for cracks or tears. Conduct a monthly fluoroscopic check of lead integrity.
• System Warm-up: Execute the manufacturer-recommended X-ray tube warm-up sequence to prevent anode cracking.

Patient Handling & Examination Protocol

• Patient Identification: Verify the patient’s identity using two identifiers (Full Name and DOB) against the imaging requisition form.
• Pregnancy Screening: Perform a mandatory verbal pregnancy screening for all patients of childbearing age; document the response in the medical record.
• Instruction: Provide clear, concise instructions to the patient regarding breath-holding and movement restrictions.
• Shielding: Apply appropriate gonadal shielding to the patient without obscuring the anatomical region of interest.
• Collimation: Adjust the collimator blades to the smallest field size necessary to capture the required anatomy, thereby reducing patient dose and scatter radiation.
• Technique Selection: Select the pre-programmed exposure technique (kVp/mAs) based on the patient’s size and the specific anatomical protocol.

Post-Examination & Shutdown Procedures

• Image Verification: Ensure all images are verified for quality and clinical relevance before dismissing the patient.
• Room Sanitization: Disinfect the examination table, upright bucky, and any contact surfaces using hospital-grade antimicrobial wipes.
• Equipment Reset: Return the X-ray tube to the neutral "parked" position and ensure the table is locked in place.
• Power Down: Follow the software shutdown sequence on the workstation; power down the generator if the room is closing for the day.
• Supply Restock: Replenish inventory such as medical-grade paper, gowns, and hand sanitizer.

Pro Tips & Pitfalls

• Pro Tip (ALARA): Always prioritize the use of the smallest effective radiation dose. If an image is diagnostic, do not repeat it to achieve "perfect" aesthetics.
• Pro Tip (Log Management): Maintain a digital log of all rejected images and their causes. This is essential for both regulatory audits and optimizing departmental workflow.
• Pitfall (Lead Apparel): Never fold lead aprons; folding causes the lead lining to crack, rendering the garment ineffective. Always hang aprons on designated racks.
• Pitfall (Room Traffic): Do not allow non-essential personnel (e.g., family members without shielding) to remain in the room during the exposure.

Frequently Asked Questions

Q: How often should lead aprons be tested for damage? A: Lead aprons must be visually inspected before every shift and subjected to a formal fluoroscopic inspection or radiograph check at least once every 12 months to detect internal cracks.

Q: What is the procedure if the "X-Ray in Use" light fails? A: If the warning light is non-functional, the room must be taken out of service immediately. Place a physical "OUT OF SERVICE" sign on the door and contact biomedical engineering for repair.

Q: Can I manually override a technique setting? A: While manual overrides are possible, they should only be used by experienced technologists for non-standard anatomy or specialized orthopedic hardware. Always prioritize the facility’s validated exposure charts.
