Final answer:
Intensifying screen, Cephalostat, and Screen Film are essential components in radiography for clear imaging.
Explanation:
Intensifying screen is used as an extension of the panorex machine to aid in taking extraoral images. It works by amplifying the light emitted by the X-ray to produce a clearer image.
Cephalostat, on the other hand, is a device used to position the patient's head during X-ray imaging, ensuring consistent and accurate positioning for cephalometric radiographs.
Screen film is a light-sensitive film that captures the X-ray image once it has passed through the patient's body or dental structures.
