Answer:

compton Question 3: An interaction which occurs between very low energy x-ray photons and matter is called

Answer:

coherent

Question 4: During photoelectric absorption, the ejected electron is called

Answer:

photoelectron

Question 5: What is the predominant interaction through most of the diagnostic x-ray range in the human body

Answer:

compton

Question 6: What is the electron dislodged during Compton scattering called

Answer:

recoil

Question 7: Patient's absorb x-ray photons

Answer:

primary Question 8: How many half-value layers must be added to the primary beam to reduce its intensity to less than 20% of its original value

Answer:

3

Question 9: Describe inherent filtration

Answer:

Anything in the tube, makes up 1.5

Question 10: Can filtration remove a portion of the useful beam

Answer:

yes

Question 11: What is backscatter

Answer:

Photon goes back in the direction it came from

Question 12: Problems of unequal subject density can be solved by using

Answer:

filters

Question 13: What happens during pair production

Answer:

Energy from the x-ray photon is converted to matter in the form of 2 electrons

Question 14: What is a photoelectron

Answer:

Ejected inner shell electron Question 15: As the tube ages, the anode begins to pit and the glass envelope may gain a mild coating of vaporized metal. This causes a in inherent filtration

Answer:

increased

Question 16: What shell electron is ejected during photoelectric absorption

Answer:

k

Question 17: What is the most common filter material used

Answer:

tungsten

Question 18: Filtration outside of the tube and housing is considered to be

Answer:

added Question 19: A photoelectric interaction is more likely to occur with an electron which is bound in its orbit

Answer:

loosely

Question 20: What happens during coherent scattering

Answer:

Photons get excited and released energy into another photon with the same wavelength and frequency.

Question 21: filtration occurs as the primary beam passes through the glass window of the x-ray tube

Answer:

Inherent

Question 22: The thickest portion of the wedge filter is placed over

Answer:

cathode

Question 23: Collimation devices are considered part of the filtration

Answer:

added

Question 24: At what energy level do electrons posses the highest total energy

Answer:

K-shell Question 25: Some x-ray photons may pass through matter and not with that matter

Answer:

interact Question 26: Most of the inherent filtration of a typical x-ray equipment comes from the

Answer:

tube Question 27: What does filtration permit the radiographer to do to the photon emission spectrum

Answer:

Remove low energy electrons and harden the beam

Question 28: Photodisintegration is relevant in diagnostic imaging ranges.

Answer:

NA
