X-ray Tube Housing
5
X-RAY Tube Housing
• Lead and steel
• Absorbs stray
radiation
• Prevents x-ray
photons from
leaking from tube
6
Collimator Knobs
7
Collimator
• Attaches directly below the xray tube
• Projects a high-intensity light
field on the patient, which
represents the area of the xray field exposure
• Serves as a beam limiting
device
• Controls size and shape of the
x-ray field

• Tilting tables
– diagnostic and
fluoroscopic work
– 90 degrees in one
direction
– 15 – 30 degrees in
the other direction
– ancillary
equipment:
Tables
• footboard,
shoulder support,
handgrips,

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

CONTROL CONSOLE
 Gives the technologist
control of the xray
machine
 Technique selection
 Located OUTSIDE of
the Radiographic
Room

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