Digital Rads
The range of exposure values (amount of X-ray radiation) that can produce an image
Exposure latitude
●Very high exposure of ionizing radiation received in a short time can cause what process?
Cell Death
In manual processing, the function of the fixer is?
Clears away the unexposed emulsion and fixes the image to the film
Beam direction is described first by ?
Where it enters the body
What parameter controls the speed and energy of electrons?
KVp
Has scintillator layer, which converts X-ray photons into light photons, and a photodetector, which converts light photons into digital signals
Indirect digital radiology
The most important part of the x-ray machine; this is where x-rays are produced
The x ray tube
In the early part of manual processing, what absorbs energy from x-rays and undergoes a physical change not yet visible?
Silver halide
Causes the intensity of radiation to be greater on the cathode side
The anode heel affect
They can be absorbed by or scattered by tissues in the body
X rays
Where are digital xray images stored?
on a PACS system
Controls the field of view
The collimater
True or false, in automatic processing the film is processed at a lower temperature vs. manual processing
False - higher temperature
What is missing: Develop, Rinse, Fix, ____, Dry
Wash
The side touching the table determines the label used
Lateral View
The images can be altered on the screen which can _________ the number of retakes
decrease
It is a thin tungsten wire that is placed in the focusing cup
The cathode
In manual processing, if the temperature of the chemicals are too cold, what happens to the image on the film?
It wont develop
Orthogonal means:
2 views at 90 degrees from each other
Material that allows x-ray photons to pass through easily; not visible on x-ray is.
Radiolucent
Patient and client information is stored in ______
A PACS system
It houses an active layer of phosphorus which gives off light when exposed to x-rays
Intensifying screen
What must staff always wear when developing film?
PPE
Dark rooms need every trace of light sealed off to:
keep light out
materials that do not allow x-ray photons to pass easily; visible on x-ray
Radiopaque
