16 Questions
What is the aim of the provided information and procedures?
To provide information and procedures for diagnosing or repairing a problem with an X-ray generator
What does Section 1 of the contents focus on?
Preparing for radiographic exposure
What does the control system do before permitting preparation to begin?
It makes a number of safety tests
What happens if all tests are satisfied during the preparation mode?
The system signals ready for an exposure
Which section focuses on diagnosing or repairing a problem with an X-ray generator?
Part 1: Nothing happens
What are flow charts provided for in the content?
To indicate logical steps when diagnosing a problem with an X-ray generator
What could be the reason for no sound of X-ray tube anode rotation?
Fault in the generator
When would a warning light indicate a fault in the generator?
Incorrect setting of the X-ray control
What would cause a warning light indicating wrong exposure factors?
kV set above the maximum X-ray tube rating
What happens if the combination of a high value of mA and a low value of kV is selected?
X-ray tube filament overheats
Why might selecting a very short exposure time combined with a low mA prevent operation?
Exceeds X-ray tube anode heat capacity
What should be done if the X-ray control microprocessor has calculated the amount of heat in the X-ray tube anode to be exceeded?
Wait a few minutes for the anode to cool down
What do modern microprocessor-controlled generators have in special display modes?
'Reduce mAs' message on the control panel
What would cause a warning light to indicate operator error?
Incorrect setting of X-ray control
When might a small symbol indicate excessive anode heat on the control panel?
'Anode heat exceeded' symbol displayed
What type of message might be displayed with microprocessor-controlled generators?
Direct message 'Reduce mAs'
This quiz provides information and procedures for diagnosing and repairing problems with a fixed installation X-ray generator in an X-ray department. It includes flow charts for logical steps when diagnosing a problem, covering issues such as bad connections, fuses, and warning signals due to fault conditions.
