ARRT registry review covering Equipment operations and quality control

QuestionAnswer
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
