For accurate localization of anatomy, how many sides of collimation must be detected?

To achieve accurate localization of anatomy during imaging, it is essential to detect all four sides of collimation. This comprehensive approach allows for precise delineation of the area to be imaged, ensuring that the anatomy of interest is appropriately represented while minimizing exposure to surrounding tissues. By identifying all four sides—upper, lower, left, and right—the radiologic technologist can confirm that the collimation encompasses the target anatomy fully, which is crucial for both diagnostic quality and radiation safety. Detecting fewer sides may lead to incomplete imaging or unnecessary radiation exposure to adjacent structures, making full collimation detection vital for effective imaging practices.
