Console Controls
A system of preprogrammed exposure techniques organized by exam and body part.
What is APR (Anatomical Programmed Radiography)
The three main parts of the x-ray imaging system.
What are the operating console, high-voltage generator, and x-ray tube
The process of converting alternating current to direct current.
What is rectification
The simplest type of x-ray power supply with the most voltage fluctuation.
What is single-phase power
Radiation quantity refers to this property of x-rays.
What is x-ray intensity (number of photons)?
What is x-ray intensity (number of photons)?
This device automatically stops the exposure when enough radiation reaches the detector.
What is Automatic Exposure Control (AEC)
The device that supplies a precise voltage to both the filament circuit and high-voltage circuit.
What is the autotransformer
This type of rectification allows only one half of the AC waveform to pass.
What is half-wave rectification
his type of power supply produces nearly constant voltage.
What is three-phase power
Radiation quality refers to this property of x-rays.
What is penetrability (energy)
The exposure factor that controls radiographic contrast.
What is kVp (kilovoltage peak)
The device that increases voltage to kilovolt levels for x-ray production.
What is the step-up transformer
This rectification method uses both halves of the AC waveform.
What is full-wave rectification
the modern generator type used in most radiography systems.
What is a high-frequency generator
The device in the bucky that absorbs scattered radiation.
What is the grid
This exposure factor controls the number of x-ray photons produced.
What is mA (milliamperage)
The transformer that lowers voltage but increases current to heat the filament.
What is the step-down transformer
The main advantage of full-wave rectification.
What is exposure time is cut in half?
The term describing variation between maximum and minimum tube voltage.
What is voltage ripple
A moving grid system used to reduce grid lines on radiographs.
What is a reciprocating (oscillating) bucky
The total amount of electrical charge used to produce x-rays.
What is mAs
The circuit that converts AC electricity to DC so electrons flow from cathode to anode only.
What is rectification
The components used to accomplish rectification.
What are rectifiers (diodes)
The generator type with the lowest voltage ripple (~1%).
What is high-frequency power
This console stage heats the filament and spins the anode before exposure.
What is the prep stage
