What should the monthly retake analysis be below? - ✔5%
What are quarterly QC tests for CR/DR/Fluoro/CT - ✔-Collimator operation (CR/DR/Fluoro)
-Interlocks (all) (on doors to prevent exposure if door is open)
-Compression devices (Fluoro)
-Table angling/motion (Fluoro)
-Fluoro protection devices (lead drapes = .25mm of pb)
-CT patient support movement
What are the annual QC tests for CR/DR/Fluoro/CT - ✔-Accuracy of loading
factors (CR/DR/fluoro)
-Output reproducibility
-Output linearity
-Beam filtration
-AEC
-Beam/light field alignment
- Beam collimation

Flexion/ Extension views of the C spine assess? - ✔Anteroposterior mobility
CR angle for an AP coccyx is - ✔10 degrees caudad
What does ERCP stand for, what 2 things is it done for? - ✔Endoscopic
Retrograde Cholangiopancreatography
1. Diagnose biliary and pancreatic pathological conditions
2. Investigate gallbladder, CBD, pancreatic ducts, and intervention
Test tool used to test focal spot - ✔Slit camera, pinhole camera, star pattern
State the line focus principle - ✔By angling the anode target the effective focal spot is
made much smaller than the actual focal spot
What are the effects of a smaller anode angle? (more vertical) - ✔-Smaller effective focal spot
-Better spatial resolution
-More anode heel effect
-Smaller max size of collimation
What is the grid ratio? - ✔The height of the lead strips divided by the distance between
lead strips
