Patient Shielding and Positioning

Selective Shielding Use

Apply patient shielding selectively based on exam type and diagnostic necessity and avoid routine use that may obscure anatomy or trigger automatic exposure increases. Use gonadal shielding for appropriate radiographic exams when it does not interfere with the diagnostic region. For CT and fluoroscopy consider bismuth or equivalent shields only after protocol optimization and vendor guidance.

Positioning and Collimation

Accurate patient positioning and tight collimation reduce irradiated volume and improve image quality by limiting scatter. Use immobilization and support devices to minimize motion and avoid repeat exposures. Train technologists in positioning techniques for diverse patient body habitus and clinical indications.

Pediatric Considerations

Children require size adapted shielding and technique selection to minimize dose while preserving diagnostic information. Use weight or diameter based protocols and prefer non ionizing modalities when feasible. Communicate with caregivers and use child friendly immobilization to reduce motion and need for repeat scans.

Documentation and Consent

Document shielding decisions and positioning rationale in the imaging record when deviations from standard practice occur. Provide clear patient information about benefits and risks and obtain informed consent for procedures with significant exposure. Use standardized checklists to ensure consistent application of protective measures.

Lead Glass Window

Overview

Lead glass windows allow staff to observe procedures while remaining protected from scatter radiation. They provide visual contact between control rooms and procedure areas. Proper installation ensures shielding effectiveness and visibility.

Optical Quality

High optical clarity and minimal distortion are important for accurate observation. Anti glare coatings and appropriate lighting improve visibility. Regular cleaning maintains optical performance.

Shielding Specifications

Lead equivalence and thickness are specified based on room design and expected scatter levels. Certification and testing verify shielding performance. Integration with room layout ensures safe viewing angles.

Maintenance and Inspection

Periodic inspection checks for cracks and seal integrity to maintain protection. Documentation of testing supports regulatory compliance. Replacement planning addresses wear and accidental damage.
