What is the tube tilt requirement for the lateral sacrum projection?

For the lateral sacrum projection, the tube tilt requirement is indeed none. When performing this projection, the X-ray beam is directed perpendicular to the film or detector, which means that no angling of the tube is necessary.

This positioning technique is designed to visualize the sacrum without distortion or unnecessary superimposition of surrounding anatomy. By keeping the tube in a perpendicular orientation, it ensures that the anatomical details of the sacrum are captured clearly and accurately, which is crucial for effective diagnosis and treatment planning in radiology.

Understanding the specific positioning requirements for different projections, including the absence of tube tilt for this particular one, is vital for radiologic technologists when positioning patients and aiming for quality imaging results.
