24
Q

Describe QC - Filtration

Study These Flashcards
A
  • To ensure that radiographic unites have min. of 2.5 mm AL
  • Determined by testing HVL
  • Done by physicist
  • Checked Annually
  • Both digital & Film screen
25
Describe QC-Collimation
- Done to ensure that the x-ray field aligns with light field - Margin of error: within 2% of SID - Checked semiannually ( 2x's / year) - Both Digital and film screen - Tested by QA personell
26
Describe Quality Control - Focal Spot Size 1. What is it 2. Margin of error 3. How many times is it checked 4. 3 tools to measure are?
-measure of spatial resolution of x-ray tube - Margin of error" within 50% - Checked annually ``` 3 tools used to measure: 1. Pinhole camera 2.Star Pattern 3.Slit camera (most common) ```
27
What is the margin of error for kVp and how often is it checked?
10% Bushong , 5% otherwise -Checked annually
28
Describe QC Exposure timer
-ensures that back up time does not exceed 6 s or 600 mAs check annually -margin of error: within 20% under 10 ms. or 5% over 10 ms
29
Which towels are best for cleaning intensifying screens
