100
This is the organization that establishes standards and provides the certification examination for radiologic technologists.
What is the ARRT
100
The quantity of matter that makes up any physicial object.
What is its mass?
100
This type of exposure timer makes it possible to expose very short exposures (1msec or less).
What is electronic timer?
100
This is a "cassette-based' digital x-ray system.
What is computed radiography (CR)?
200
This is the term to describe a pattern of exposure on a film that has been exposed but has not yet been processed.
What is latent image?
200
The unit that potential difference is measured in.
What are volts?
200
A series of warm-up exposures is made for this purpose.
What is preventing damage to the anode from sudden heating?
200
A phosphor in a CR plate can be reused this many times.
What is 10,000 times?
300
This is termed the IR.
What is the image receptor. The film and cassette, image receptor plate or digital receiver plate.
300
This material makes up the target of the x-ray tube.
What is tungsten?
300
This increases the voltage on the secondary side to provide an appropriate current to heat the filament.
What is a step-up transformer?
300
This system is used to view and store digital x-ray images.
What is PACS?
400
This is the principal source of scatter radiation.
What is the patient?
400
This is the charge of the anode, or targe of the x-ray tube.
What is positive?
400
This is referred to as a "programmed technique chart" in the control consul.
What is APR (anatomically programmed radiography)?
400
When a CR plate is inserted into the reader for processing, the phosphor is scanned with this kind of light.
What is a laser light?
500
Absorption of x-rays by matter is called this.
What is attenuation?
500
The mAs used for an exposure determines this.
What is the quantity of radiation of the exposure?
500
This is the process of causing alternating current to flow in one direction only.
What is rectification?
500
Barium fluorohalide with europium is used here.
What is the phosphor that absorbs the x-ray energy in a CR plate?
