11 Questions
What is the primary consequence of the coherent scattering process described in the text?
The incident photon is scattered with no loss of energy.
What is the primary reason that coherent scattering is of little significance in most diagnostic procedures?
The scattered radiation does not leave the beam.
Which of the following properties of the incident photon is most important for the coherent scattering process to occur?
Low energy of the photon.
Which of the following terms is used to describe the coherent scattering process described in the text?
Coherent, classical, elastic, or Thomson scattering
What is the primary mechanism by which the incident photon interacts with the electron in the coherent scattering process?
The photon excites the electron, causing it to vibrate.
What does the linear attenuation coefficient measure?
Probability of photon interaction per unit length
How is the linear attenuation coefficient value affected by the number of atoms in a material?
Increases with more atoms
What calculation can be made using the transmitted intensity equation and linear attenuation coefficients?
Estimating the thickness of the material
In what situations can the incident x-ray energy be determined using linear attenuation coefficients?
When material thickness and transmitted intensity are known
What information is needed to determine the material from the value of μ?
Incident and transmitted intensity
How does the fraction of photon interaction in the 1-cm thickness impact the linear attenuation coefficient?
Fraction directly determines coefficient
Learn about the coherent scatter process in photon interaction where incident photons interact with tightly bound electrons to cause vibration and scatter the photon, with no energy loss or secondary effects. This occurs with low-energy photons and at small angles of scattering.
