X-RAY Tube Housing

• Lead and steel

• Absorbs stray radiation

• Prevents x-ray photons from leaking from tube

Collimator Knobs

Collimator

• Attaches directly below the x-ray tube

• Projects a high-intensity light field on the patient, which represents the area of the x-ray field exposure

• Serves as a beam limiting device

• Controls size and shape of the x-ray field

Tables• Tilting tables – diagnostic and

fluoroscopic work– 90 degrees in one

direction – 15 – 30 degrees in

the other direction– ancillary
