2. Patient Protection Measures

• Use of lead shielding for sensitive areas (gonads, thyroid, breasts).
• Avoid unnecessary repeat X-rays by ensuring proper positioning and exposure settings on the
first attempt.
• Special precautions for pregnant patients, including alternative imaging options (e.g.,
ultrasound, MRI).

Orthopaedic Technologist’s Role in Imaging Assistance

Orthopaedic technologists are essential in assisting with imaging procedures by ensuring
accurate patient positioning, optimizing image quality, and adhering to radiation safety
protocols. Their role is crucial in obtaining high-quality diagnostic images while minimizing
unnecessary exposure to radiation. Additionally, they act as a liaison between patients, radiologic
technologists, and orthopaedic specialists to ensure smooth workflow and improved patient care.

Orthopaedic technologists may be responsible for ensuring accurate patient positioning,
assisting in imaging procedures, and maintaining radiation safety standards.

1. Responsibilities in the Imaging Process

a. Patient Preparation and Positioning

• Educate patients on the procedure, positioning requirements, and the importance of staying
still to avoid motion artifacts.
• Ensure accurate anatomical positioning to obtain the best diagnostic images.
• Use positioning aids such as foam pads, straps, or sandbags to stabilize the extremity or joint.
• Confirm that metal objects (jewelry, implants, or external devices) are either removed or
properly accounted for to prevent image distortion.

b. Equipment Preparation and Optimization

• Verify that X-ray machines, cassettes, and digital imaging detectors are functioning correctly
and are properly aligned.
• Adjust exposure settings (kVp, mAs) based on patient size, tissue density, and body part
being imaged.
• Check grid usage to reduce scatter radiation and enhance image contrast when imaging thicker
body parts.
• Utilize collimation techniques to focus the X-ray beam on the area of interest, reducing patient
dose and improving image clarity.

c. Radiation Protection and Safety Compliance

• Implement the ALARA (As Low As Reasonably Achievable) principle to minimize radiation
exposure.
