Standard Operating Procedure: X-Ray Room Operations

This Standard Operating Procedure (SOP) outlines the mandatory protocols for the safe, efficient, and regulatory-compliant operation of the X-Ray suite. As an expert-managed facility, our priority is the optimization of image quality while strictly adhering to the ALARA (As Low As Reasonably Achievable) principle to ensure radiation protection for patients, staff, and the general public. All personnel must review these guidelines to maintain compliance with departmental safety standards and legal diagnostic imaging requirements.

1. Pre-Examination Room Preparation

• Safety Inspection: Confirm the lead apron, thyroid shields, and protective goggles are free of cracks or damage (perform visual and tactile inspection).
• Equipment Calibration: Power on the generator and console. Run the automated quality control (QC) sequence to ensure the tube and detector are communicating correctly.
• Sanitation: Utilize hospital-grade disinfectant wipes on the table surface, bucky tray, and control console touchpoints.
• Consumable Audit: Verify an adequate supply of patient gowns, drapes, and positioning sponges is readily available.

2. Patient Intake and Screening

• Identity Verification: Confirm the patient's identity using two identifiers (Full Name and DOB) against the digital radiology order.
• Pregnancy Screening: Mandatory verbal and written screening for female patients of childbearing age (10–55 years) to rule out pregnancy.
• Clearance: Remove all radiopaque objects (jewelry, piercings, bras with underwire, zippers) from the area of interest.
• Informed Consent: Clearly explain the procedure to the patient and confirm they understand the purpose of the exam.

3. Positioning and Radiation Safety

• ALARA Execution: Use the smallest field size (collimation) necessary to cover the anatomy of interest.
• Shielding: Apply gonadal shielding for patients of reproductive age if it does not interfere with the diagnostic quality of the image.
• Distance/Barrier: Ensure all staff members are behind the leaded control booth glass before initiating exposure.
• Verification: Double-check the SID (Source-to-Image Distance) and detector alignment to prevent magnification errors.

4. Post-Examination Protocol

• Image Review: Verify that the images are diagnostic, free of motion blur, and correctly labeled with the appropriate anatomical markers (R/L).
• Patient Discharge: Provide the patient with instructions on when to expect results or any necessary follow-up care.
• Equipment Reset: Return the X-ray tube to the park position and ensure the room is organized for the next patient.
• Documentation: Log the exposure indices and any repeat images in the digital logbook for departmental auditing.

Pro Tips & Pitfalls

• Pro Tip: Always utilize the "Collimator Light" to guide your positioning before the patient enters the room; this minimizes patient time on the table and reduces anxiety.
• Pro Tip: If the equipment displays an error code, do not attempt a hard reset more than once. Power down and call clinical engineering immediately.
• Pitfall: Never rely on a patient’s "memory" regarding pregnancy. If they are unsure, a urine or blood pregnancy test must be performed before ionizing radiation is administered.
• Pitfall: Ignoring "Repeat" images. If you are consistently getting poor images, do not just "make do." Notify the lead tech or clinical supervisor to check for potential tube or sensor drift.

Frequently Asked Questions (FAQ)

Q: What should I do if a patient refuses to remove a metallic item that is not in the field of view? A: If the item is clearly outside the primary beam, explain the impact of scatter radiation, but prioritize patient comfort. If the item is in the field of view, it must be removed. If the patient refuses, document the refusal in the EMR and consult the Radiologist on call.

Q: How often should lead aprons be inspected? A: Per regulatory standards, lead-lined protective gear must be fluoroscoped for cracks or tears at least once every 12 months. Visual inspection should occur during every shift.

Q: What is the procedure if the emergency stop button is pressed? A: Do not panic. Determine the cause of the emergency. Once the area is cleared, ensure the patient is safe, perform a full system reboot, and report the incident in the hospital’s safety reporting system (e.g., RLDatix or equivalent).
