D
What the acronym "DQE" stands for.
What is "Detective Quantum Efficiency"?
Higher DQE means this for a patient.
What is lower dose?
DQE measures this.
What is the overall efficiency for converting input data into useful output images?
Kyle from Altru went to college here instead of Northland.
Where is Minnesota State Detroit Lakes?
This is why an image could be underexposed even when using the same technical factors.
What is low efficiency DQE?
This is a perfect DQE.
What is 1.0 or 100%?
This is why indirect conversion DR receptors have higher DQE.
What is scintillation layer?
We have this many different clinical sites.
What is 9?
Percentage of photons that get absorbed by different types of detectors.
What is capture efficiency?
This is the type of system capable of producing a perfect DQE.
What is nothing?
Typical DQE for indirect conversion DR receptors at 70 kVp?
What is 77%?
Austin works here.
What is Happy Harry's Bottle Shop 32nd Avenue S
Increasing kVp does this in relation to DQE.
This is the part of the x-ray that is converted by the system and is dependent on DQE.
What is remnant beam?
Typical DQE for direct conversion DR receptors at 70 kVp.
What is 67%?
Imaging modalities that do NOT require additional schooling in most states. (HINT: Five)
The formula to calculate DQE.
What is DQE= SNR2 out/SNR2 in?
Random information created by the electronic components of a system.
What is system noise?
Typical DQE at 70 kVp for CR phosphor plates.
What is 30% or less?
Minnesota does not require additional schooling or licensure to work in this modality.
What is Nuc Med?
The five parts of imaging that determine DQE.
What is type of imaging system, capture efficiency, beam kVp, system noise, and spatial frequency?
