Standard Operating Procedure: X-Ray Room Operations

This Standard Operating Procedure (SOP) outlines the mandatory safety protocols, equipment handling procedures, and diagnostic workflows for the X-ray imaging suite. As an operations manager, the primary objective is to ensure radiation safety (ALARA principle—As Low As Reasonably Achievable), maintain optimal diagnostic image quality, and minimize equipment downtime. All staff must adhere to these guidelines to ensure compliance with regulatory health standards and to provide a secure environment for both patients and medical personnel.

Section 1: Pre-Operational Checks

• Radiation Safety Audit: Confirm all lead aprons, thyroid shields, and leaded glasses are present and undamaged. Ensure the "X-Ray in Use" warning light is functional.
• Equipment Initialization: Power on the X-ray generator, console, and digital image receptor (DR/CR system).
• Calibration Verification: Perform a daily exposure consistency check according to the manufacturer’s QC log.
• Software Readiness: Ensure the Radiology Information System (RIS) and PACS connectivity are stable and that patient worklists are populated.
• Sanitation: Wipe down the examination table, upright bucky, and handles with hospital-grade disinfectant wipes. Replace the table cover/sheet.

Section 2: Patient Intake and Safety

• Patient Verification: Verify the patient’s identity using two identifiers (Full Name and DOB).
• Pregnancy Screening: Conduct a mandatory pregnancy status inquiry for all patients of childbearing age per clinic policy.
• Consent and Preparation: Explain the procedure clearly, obtain necessary consent, and ensure the patient removes all radiopaque items (jewelry, piercings, metal fasteners) from the area of interest.
• Shielding: Apply lead shielding to the patient if the anatomy allows and if it does not interfere with the diagnostic field of view.

Section 3: Exposure and Imaging Protocol

• Positioning: Align the patient precisely with the X-ray tube and the image receptor. Utilize sponges or positioning aids to ensure stability and reduce the need for retakes.
• Technique Selection: Select the appropriate anatomical preset (kVp/mAs) based on patient body habitus. Do not deviate from established exposure charts without radiologist approval.
• Safety Clearance: Confirm all staff and escorts have exited the room or are positioned behind the leaded control booth glass.
• Exposure: Announce "X-Ray!" or "Exposure!" clearly before depressing the exposure switch. Maintain visual contact with the patient through the observation window.

Section 4: Post-Procedure and Documentation

• Image Quality Review: Verify the images on the console for motion blur, correct density/contrast, and proper inclusion of anatomical landmarks before releasing the patient.
• Data Transmission: Ensure the images are successfully sent to the PACS/Radiologist queue.
• Patient Discharge: Provide the patient with post-procedural instructions and escort them to the dressing area.
• Room Reset: Return the X-ray tube to its home position, clear the floor of any clutter, and sanitize the examination surface again.

Pro Tips & Pitfalls

• Pro Tip: Always utilize the "collimation" feature to the smallest possible area of interest. This reduces scatter radiation and significantly improves image contrast.
• Pro Tip: Perform a visual inspection of lead aprons every 6 months using fluoroscopy to identify potential "cracks" in the lead lining.
• Pitfall: Never bypass safety interlocks. If a door sensor fails, lock the room and contact maintenance immediately; the risk of accidental exposure is non-negotiable.
• Pitfall: Avoid "technique creep." Technicians often increase exposure factors to hide poor positioning; focus on precise anatomical alignment rather than higher radiation doses.

FAQ

Q: What should I do if the X-ray unit displays an error code? A: Record the exact error code, power down the system completely, wait 60 seconds, and restart. If the error persists, do not attempt a reset; tag the machine as "Out of Service" and contact biomedical engineering.

Q: How often should the X-ray room undergo professional maintenance? A: Preventive maintenance (PM) should be performed at least annually by a certified field engineer, or more frequently if the throughput exceeds the manufacturer's recommended duty cycle.

Q: Is it mandatory to wear a personal dosimeter badge? A: Yes. All staff working in the X-ray suite must wear their assigned dosimetry badge at the collar level outside the lead apron to track cumulative radiation exposure accurately.
