FINAL STUDY 201
| Question | Answer |
|---|---|
| With exposure values whats the best way to reduce motion | reduce mAs |
| filtration does what to does to exposure | decreases dose |
| filtration does what to the quality of the beam | improves |
| filtration does what to the quantity of photons | decreases |
| what is total filtration | the aluminum shutter, tube hosuing, and oils withing the housing |
| what is the added filtration | the added shutters, that create collimation |
| how does collimation help image quality | be reducing scatter |
| what happens when there is insuffencent exposure | noise (quantom mottle) |
| what is kvP | penatrability |
| what is mAs | intensity |
| which side of exposure will normal be less | the anode side due to heel effect |
| why does heel effect occur | because some on the beam is absorb in the anode resulting in uneven exposure across the field. |
| Best kvp and mA setting to reduce exposure to the patient | high kVp and lower mA |
| if (one) HVL is applied to 100 how much will hit the patient | 50 |
| if (3) HVL is applied to 120 how much will hit the patient | 15 |
