5. This is a modern rotating anode x-ray tube. It is encased
completely in a metal protective housing.
There are two principle parts:
•The rotating anode(acts as the target for electrons and
releases x-rays)
•The cathode(provides a source of electrons)
Purpose:
– Controls leakage & off-focus radiation
– Isolates high voltages
– Helps to cool the tube

7. OPERATING
CONSOLE
THE CONSOLE IS THE PART OF MACHINE THAT
CONTROLS THE OPERATION OF X-RAY MACHINE
ALL MACHINE CONSOLE ARE LITTLE DIFFERENT BUT
THERE ARE ALWAYS SIMILARITIES.
THE CONSOLE IS WHERE WE CONTROL THE X-RAY TUBE
CURRENT,VOLTAGES LINE COMPENSATION.
8. HIGH VOLTAGE
GENERATOR
A single phase HV generator can take the power
supplied by AC mains rectify it & transform
Rectification process is either in half wave or full
wave to remove any negative going voltages, which
would otherwise excite an anode to act as electron
source.
9. TUBE HEAD
The external structure of x-ray tube consists of
3 parts
1.The support system
2.the protective housing
3.glass or metal enclosure
10. PROTECTIVE HOUSING
The x-ray photons are
generated isotropic
ally or in all directions.
The housing is
designed to limit the
beam to window.
11. PROTECTIVE HOUSING – PREVENT
DAMAGE
The housing also provide mechanical support
and protection from damage.
On some tubes, the housing also contains oil
that provides more insulation and a thermal
cushion.
12. Collimators
Beam restricting device.
it’s considered the best beam restricting
device.
remove unwanted radiations.
13. A collimator has two or three sets of lead shutters.
Located immediately below the tube window, the
entrance shutters limit the x-ray beam.
One or more sets of adjustable lead shutters are
located 3 to 7 inches (8 − 18 cm) below the tube.
14. GRID
IT’S MADE UP OF LEAD MATERIAL
ITS INSERTED B/W PATIENT AND THE FILM
PURPOSE
REDUCE THE SCATTERED RADIATION
IMPROVE IMAGE CONTRAST.
15. X-RAY TABLES OR PATIENT
TABLES
CHARACTERISTICS
•RADIOLUCENT MATERIAL
•EASILY CLEANED
•SCRATCH RESISTANT
•BUCKY TRAY
•BUCKY SLOT COVER
•GRID
16. BUCKY
A BUCKY IS TYPICALLY USED FOR TABLE
OR WALL MOUNTED X-RAY SYSTEMS AND
HOLDS THE X-RAY CASSETTE AND GRID. A
BUCKY IS A DEVICE FOUND UNDERNEATH
THE EXAM TABLE, A DRAWER LIKE DEVICE
THAT THE CASSETTE AND GRID IS SLID
INTO BEFORE SHOOTING X-RAY.
