Question:
What are the 5 types of patient interactions?

Answer:
1. coherent scattering
2. photoelectric
3. compton scattering
4. pair production
5. photodisintegration


Question:
What energy level does coherent scattering occur?

Answer:
below 10 keV


Question:
What energy level does photoelectric occur?

Answer:
Low kVp


Question:
What energy level does compton scattering occur?

Answer:
All energies


Question:
At what energy level does pair production occur?

Answer:
1.02 MeV


Question:
At what energy level does photodisintegration occur?

, Answer:
10 MeV


Question:
Which 2 interactions are important to our diagnostic range?

Answer:
compton scatter and photoelectric


Question:
Explain photoelectric interactions

Answer:
occurs with a low kVp, secondary radiation occurs through
characteristic cascading, long wavelength/low frequency


Question:
Explain Compton scattering

Answer:
happens in all matter, more matter more scatter, any energy
level


Question:
Which interaction results in image noise and reduces contrast?

Answer:
Compton Scattering


Question:
Additional names for Classical Scatter.

Answer:
coherent, thompson, rayleigh


Question:
why doesn't classical scattering normally occur in the patient
at our diagnostic range?
