Xray - Outcome 8

Question 1

The basic factors in rotational panoramic radiography include:

Answer 1

A narrow vertical slit beam of X-rays is used to scan a stationary object

The tubehead and film carrier are connected to each other; they circle around the object so that the X-ray beam turns around a pivotal point (rotation axis) in the object

While the tube and film carrier are moving, the film also moves behind a scatter guard

The film moves through the X-ray beam at the same rate as the layer being imaged in the object. Therefore, when one inch of film moves through the x-ray beam, the layer in the object where one inch of depth has been scanned by the beam appears sharp in the radiograph layers past that depth appear blurred
