RADT 334 X-ray tube
radiographic physics review covering X-ray tube
| Question | Answer |
|---|---|
| What are the three main components of the x-ray imaging system? | the tube, the operating console, and the high voltage generator |
| What is the purpose of the operating console? | controls the voltage applied to the x-ray tube, and controls the current through the x-ray tube and exposure time |
| What is the purpose of the line voltage meter? | it is the power supply of the x-ray circuit |
| That does the autotransformer do? | supplies a precise voltage to the filament and high voltage circuit |
| What is the line voltage compensator? | controls the voltage coming in to 220 v |
| What does kVp control? | the quality of the beam |
| What does mAs control? | the quantity of the beam |
| What are the four types of exposure timers? | synchronous, electron, mAs timers, AEC |
| What are the three primary parts of the high voltage generator? | high voltage transformer, the filament transformer, and rectifiers |
| What is rectification? | converting alternating current to direct current. allows current to flow in one direction |
| Which generator generally produces the best x-rays? | three phase six pulse |
| What is the ripple of a half wave? | 100% |
| What is the ripple of three phase six pulse? | 14% |
| What is the ripple of three phase, twelve pulse? | 4% |
| What is the ripple of three phase high frequency? | 1% |
| What is the ripple of a full wave? | 100% |
| What is the purpose of a fuse? | keeps volts from back tracking and electrocuting the technologist |
| How many volts should the operating console operate on? | 220 v |
| How many windings does the autotransformer have? | single winding |
| How many amps does the filament circuit run on? | 5-8 amps |
| What kind of current must the x-ray tube have? | direct current |
| What is a diode? | electronic device that contains two electrodes whose electrons from on one direction |
| What are the types of generators? | single phase, three phase, high frequency, capacitor discharge |
