What is indicated by a radiographic side marker?

A radiographic side marker is used to indicate the side of the patient that is being imaged. This is crucial in ensuring clear communication and proper interpretation of the x-ray films, as it provides essential information about the anatomical orientation. Accurate side marking helps healthcare professionals avoid confusion, especially in cases where the images are reviewed later or by different personnel. The side marker usually specifies whether the left or right side of the body was imaged, which is vital for diagnosis and treatment planning.

While operator identification, the type of examination, and exposure time are important aspects of radiography, they do not convey the immediate anatomical orientation that the side marker does. Therefore, the primary role of the radiographic side marker is to indicate which side of the patient is being viewed in the imaging.
