Question

Quizplus · Accepted Answer

The area between the x-ray source and the image receptor that will be recorded in relative detail on the resultant radiograph is known as the focal trough or the "zone of sharpness". This is the area where the anatomy is in focus and appears clearly on the radiograph. The negative shadow is an area on the radiograph where no radiation has passed through the patient, creating a white area. A ghost image is an artifact that appears on the radiograph as a faint duplicate of an object due to radiation bouncing off other structures. The rotational center is the point at which the x-ray tube and image receptor rotate around during a cone beam CT scan.
