X-Ray Production
These are the two types of interactions within the x-ray tube
What are Brems and Characteristic
Increasing the OID does this to the quality of your image
What is decrease
This converts x-ray photons into light
What is the input phosphor
This automatically increases the intensity of the x-ray beam in order to maintain brightness.
What is the Automatic Brightness Control (ABC)?
The discovery of X-rays was on this date
What is Nov. 8, 1895
This German term means "breaking"
What is Bremsstrahlung
These are the two visibility properties
This will convert the electrons into intensified light
What is the output phosphor
This replaces the image intensifier from conventional fluoroscopy
What is the flat panel detector
Fluoroscopy was discovered in this year by Thomas Edison
What is 1896
These photons are exiting the patient having no interactions with anatomical structures
What is transmitted
Doing this to your kVp would be equivalent to halving the mAs.
What is decreasing by 15%
These five parts make up the image intesifier
What are input phosphor, photo-cathode, electrostatic focusing lenses, anode, output phosphor
When converting from analog to digital, use this
What is an ADC
In the first x-ray image, this object on the fourth phalange is known as what and may be a cause for a repeat image
What is an artifact
An increase in tube filtration will cause the x-ray beam to do this while not effecting your discreet line.
What is increase
This combination of rows and columns made up of many pixels is how a digital image is recorded
What is matrix
This is the most commonly used camera tube
What is vidicon
Similar to a strobe light, a radiographer can use this setting on the control pannel
What is pulse
What area of the influences the amount of penumbra on an image
What is focal spot size
This is the total amount of inherent filtration in the x-ray tube
This is the result of great differences in radiation absorption for tissues that have greater variation in composition
What is higher subject contrast
Regarding resolution, this is the weakest link in the fluoroscopic chain.
What is the monitor?
This avoids the need to enter patient information multiple times and allows all RT modalities and gives the ability to relay information between different vendors and phone-line communications
What is DICOM System
This discovery on Nov. 8, 1895 by a German physicist represents a letter in the NATO Phonetic alphabet
What is "X"
