Question

Quizplus · Accepted Answer

The OID (object-to-image distance) is the distance between the object being imaged and the image receptor. When the OID is large, excessive magnification occurs, making the image appear larger than the actual size of the object. To reduce this, the SID (Source-to-Image Distance) needs to be increased. This means moving the x-ray tube farther away from the patient or object being imaged. This reduces magnification and improves image resolution. Increasing kVp or decreasing SID will not reduce excessive magnification.
