The percentage of target interaction that result in the production of x-ray photons.
What is less than 1% (1% will be accepted as an answer)
100
The L shell can hold this maximum number of electrons.
What is 8?
100
10 to 20% of these interactions are produced in the diagnostic x-ray range.
What are characteristic interactions?
100
The process in which an x-ray photon undergoes when it passes through matter.
What is attenuation?
100
The process in which x-ray photons interact with matter, and change direction is called.
What is scatter?
200
These are the two types of target interactions.
What are Bremsstrahlung (brems) and characteristic?
200
During this process, after an outer shell electron has dropped to fill the hole, another electron will drop to fill the hole it left and so on until only the outermost shell is missing an electron.
What is characteristic cascade?
200
This exposure setting controls the maximum possible energy for any photon that exits the x-ray tube.
What is kVp?
200
Of the K,L,M, and N energy level electrons the one which possess the highest total energy.
What is the N? 2n squared
200
This occurs when an x-ray photon with a slightly greater energy than the binding energy of the inner-shell electron interacts with that inner-shell electron.
What is photoelectric absorption?
300
Almost all kinetic energy is converted into this.
What is heat?
300
Electrons will undergo this many interactions to dissipate all of their excess energy.
What is 1,000+?
300
The primary x-ray beam photons have an average keV energy of _____ to _____ of the kVp.
What is 30 to 40%?
300
Binding energies __________ as the electron shells move further away from the nucleus.
What is decrease?
300
This occurs when an incident x-ray photon interacts with a loosely bound outer shell electron.
What is Compton scattering?
400
These interactions may only occur when the incident electron interacts with the force field of the nucleus.
What is a bremsstrahlung interaction?
400
These types of electrons always flow from the cathode filament to the anode.
What are incident electrons?
400
These two factors control the quantity of electrons in the x-ray beam.
What are mA and time?
400
total electron energies _______ as they move further away from the nucleus.
What is increase?
400
During photoelectric absorption the ejected electron is called.
What is a photoelectron?
500
During a characteristic interaction, the kinetic energy of the incident electron must be __________ _________that of the electron it knocks from orbit.
What is greater than?
500
________ are characterized as electromagnetic waves having short wavelengths and high frequencies.
What are x-rays?
500
As generator phasing efficiency increases, the x-ray beam __________ in intensity, and there is also an _________ in the average photon energy.
What is increases, increase?
500
During Compton scattering the dislodged electron is called.
What is the recoil electron?
500
During this x-ray interaction with matter, the scattered photon possesses the same energy, same frequency, and the same wavelength as the incident photon.
