|
||||
| list at least 5 properties of x-rays | show 🗑
|
||||
| show | wavelength
🗑
|
||||
| show | .1-.5 Angstroms
🗑
|
||||
| what is the definition of: LET | show 🗑
|
||||
| what are examples of high & low LET? | show 🗑
|
||||
| show | particulate = alpha, beta ...... photon = x-ray, gamma
🗑
|
||||
| what is the definition of: NBR types | show 🗑
|
||||
| show | ability of ionizing radiation to produce biologic effect relative to same amount of 200 keV x-ray required to produce similar effect. EX. epilation & errythema
🗑
|
||||
| show | exposure in air of x or gamma up to 3 meV (usded with skin entrance exposure)
🗑
|
||||
| what is the definition of: Rem (sV) | show 🗑
|
||||
| what is the definition of: Rad (Gy) | show 🗑
|
||||
| what is the definition of: HVL | show 🗑
|
||||
| what is the definition of: attenuation | show 🗑
|
||||
| list 4 factors that affect attenuation | show 🗑
|
||||
| show | time it takes a radioactive substance to reduce by 1/2 its original energy
🗑
|
||||
| what is the definition of: biological half life | show 🗑
|
||||
| what is the definition of: filtration | show 🗑
|
||||
| show | high
🗑
|
||||
| high kVp is _________ beam quality? | show 🗑
|
||||
| high kVp is _________ frequency? | show 🗑
|
||||
| high kVp is _________ s/s? | show 🗑
|
||||
| show | high
🗑
|
||||
| show | low
🗑
|
||||
| high kVp is _________ contrast scale? | show 🗑
|
||||
| what is the interaction that is most common in diagnostic? | show 🗑
|
||||
| what interaction gives you contrast? | show 🗑
|
||||
| show | Compton
🗑
|
||||
| show | it reduces contrast because the more the s/s the lower (gray) the contrast
🗑
|
||||
| what happens to the incident x-ray photon in: Photoelectric Effect | show 🗑
|
||||
| show | the incident x-ray interacts with an outer shell e- and ejects it from the atom, ionizing the atom. The ejected atom is called a compton electron. The x-ray continues in a different direction with less energy
🗑
|
||||
| name the predominant interaction in the diagnostic x-ray range | show 🗑
|
||||
| Differentiate between secondary and s/s radiation | show 🗑
|
||||
| show | >1.02 meV
🗑
|
||||
| in order for photodisintregration to occur, the incident photon must have energy of at least ______ | show 🗑
|
||||
| show | when an incident x-ray is totally absorbed during the ionization of an inner-shell e-. The incident photon disappears & the k-shell e-, now called a photoelectron, is ejected from the atom w/ the same energy as the incident x-ray called CHARACTERISTIC RAD
🗑
|
||||
| why does the probability of PE interaction decrease with increasing kVp? | show 🗑
|
||||
| the wavelength of EM radiation ________ as the energy decreases | show 🗑
|
||||
| show | quality or HVL
🗑
|
||||
| Differentiate between the 2 types of classical s/s | show 🗑
|
||||
| what is coherent s/s | show 🗑
|
||||
| show | 180 degrees
🗑
