IR of Conventional X-ray?

Film Screen Cassette

IR of Computed Radiography

Imaging Plate

IR of Digital Radiography

Flat Panel Detector

represents the amount of current passed through the X-ray tube.

determines the number of photons the X-ray tube produces, also known as X-ray quantity.

Current

Total exposure time is measured in what unit?

Seconds

controls the length of the x-ray exposure by determining how long the current (mA) will be passing through the x-ray tube.

Exposure time

measure of radiation produced (milliamperage) over a set amount of time (seconds) via an x-ray tube.

Milliampere-seconds (mAs)

calculation for receptor exposure formula

mas1 over mas2 equals D1^2 over D2^2

pertains to mAs in the sense that all combinations of mA x seconds that amount to an equal quantity will produce the same amount of density.

Reciprocity Law

________ with a longer time allow for less patient motion

smaller mA

measures how much scatter is removed by the grid and how the mechanical factors be adjusted to produce the same optical density.

Bucky Factor

ratio of the mAs required with the grid to the mAs required without the grid to produce the same optical density

Bucky Factor

Use of grid increases what by the Bucky?

Patient dose

of a film represents the amount of radiation required to produce a radiograph of acceptable density.

Speed Class

As the speed of the film increase, the amount of radiation needed to properly expose it will what?

Decrease

Increasing speed also decreases image noise. True or False

False. Increase

Speed for routine work: Speed for high detail:

• 200-800 • 50-100

speed films that are small grain, better definition, more exposure

Slow speed films

Letter of each Fast Speed Films (ultra ekta speed) (ekta speed) (ultra speed)

F E D

can be measured by - intensification factor, - relative name or speed value

Screen Speed

exposure required to create a certain optical density without a screen is divided by the exposure required with a screen to create the same optical density determines?

Intensification Factor

distance between the x-ray tube and the image receptor is the

Source to Image Distance (SID)

Screen speed used for high resolution?

Slow

Screen speed used for regular/standard

Medium

Screen speed used for fast screen?

Fast
