ARRT registry review covering Equipment operations and quality control
| Question | Answer |
|---|---|
| What x ray interaction is an electron approaching a positive nuclear charge changes direction and loses energy | bremsstrahlung |
| light sensitive AEC devices | phototimers |
| what control functions to compensate for changing patient/part thickness during fluoroscopic procedures | automatic brightness control |
| As kV increases, HVL | increases |
| as window level increases, brightness | increases |
| circuit devices that allow electrons to flow in only one direction | solid-state diodes |
| A device that converts mechanical energy into electrical energy | generator |
| a slit camera is used to measure | focal-spot size and spatial resolution |
| a type of x ray tube that is designed to turn on and off rapidly that provides multiple short and precise exposures | grid-controlled |
| the voltage ripple associated with a 3 phase, 12 pulsed rectified generator | 13 % |
| the device that receives the remnant beam, converts it into light, and then increases the brightness of that light is called | image intensifier |
| this device replaces the image intensifier's television camera tube in digital fluoroscopy | charge-coupled device |
| A procedure involving reciprocal motion of the x-ray tube and the IR | tomography |
| in fluoroscopy the automatic brightness control is used to adjust | kV and mA |
| the auto-transformer is adjusted by | kV |
| star and wye configurations are related to | three-phase transformers |
| what is a beam splitter | a device that directs the light emitted from the image intensifier to various viewing and imaging apparatus |
| to test the congruence of the x ray beam with the light field you use | radiopaque objects |
| kV must be accurate to within | +/- 4kV |
| equipment that is mandatory for a myelogram | tilting x ray table |
| device that is used to change alternating current to unidirectional current | solid-state diode |
