Which of the following is not one of the five basic x-ray interactions with matter?
Bremsstrahlung
Which of the following x-rays would be most likely to undergo classical scattering?
5 keV
Which of the following interactions contributes to image noise?
Compton scattering
During the compton effect, most of the incident x-ray energy is given to which of the following?
Scattered x-ray
After compton scattering, the scattered x-ray has
longer wavelength
Compton interaction affects the image by increasing which of the following?
Noise (fog)
The probability that an x-ray will interact with an outer shell electron is influenced principally by:
The energy of the incident x-ray
The compton interaction involves so called "unbound" electrons because:
The have a very low binding energy
Which of the following is the x-ray interaction that does not cause ionization?
calssical scattering
The photoelectric effect is principally associated with which of the following?
Absorbtion of an x-ray
The radiographic image is formed principally by which of the following?
Photoelectric interactions
The photoelectric effect is:
The complete absorbtion of an x-ray eith the subsequent emission of an electron
Differential absorbtion, although a complicated process, is basically the result of differences between:
photoelectric effect and transmission
At what approx x-ray energy is the probability of a photoelectricinteraction in soft tissue equal to the probability of a compton interaction?
20keV
Differential absorbtion is:
The difference betweenh those x-rays that are absorbed and those that are transmitted
As kVp increases, the realative number of x-rays:
that interact with tissue decreases
High kVp in chest radiography will
reduce patient dose
Increasing kVp in x-ray imaging will:
reduce skin dose
