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.
