X-RAY Tube Housing
• Lead and steel
• Absorbs stray radiation
• Prevents x-ray photons from leaking from tube
8
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
12
Tables• Tilting tables – diagnostic and
fluoroscopic work– 90 degrees in one
direction – 15 – 30 degrees in
the other direction– ancillary
equipment:• footboard,
shoulder support, handgrips, compression bands

Tube SupportsDesigned to help technologists with various
tube locations for creative imaging.
Tube suspension systems are available in 5 versions

Tube Movement
• Longitudinal
• Transverse
• Vertical
• Angling or Rolling
• Rotating
• Telescoping
CONTROL CONSOLEGives the
technologist control of the xray machine

The Control Console
• Set technical factors (mAs & kVp)
• Make an exposure
• Only a legally licensed individual is authorized to energize the console

Mobile X-RAY equipment
• Portables– Take machine to
patient
– Still images
• C-arm– Used in
interventional procedures
– Used in surgery
– Dynamic images
– Fluoroscopy
