provide a controlled flow of electrons intense
enough to produce an x-ray beam
appropriate for imaging.

5. Components of x-ray imaging
systems:
 The x-ray tube
 The operating console
 High voltage generators

 High voltage generators

6. The operating console:
 Controls the x-ray tube current.
 Controls the x-ray tube voltage.
 Control the exposure time.
 Ensure x-ray beam produced is of proper
quantity and quality.
 Quantity is the no. of x-rays or the intensity of
the beam (mR or mR / mAs).
 Quality is the penetrability of x-ray beam
(kVp or HVL).6

7. High –voltage generators:
 Contains the high-voltage step-up
transformer.
 Contains the rectification circuit.

8. X-ray imaging systems; identification:
 Depends on the energy of x-ray produced, or
 Intended use, or purpose
 Usually operates at 25-150 kV and 100 to
1200 mA tube current.
 General purpose x-ray examination room will
have a radiographic as well as fluoroscopy
systems.
