Physics Chapter 7 Term Quiz Flashcards
An event that the incident x-ray photon interacts with an orbital electron of a tissue atom and change direction
Classical Scattering
When an incident xray photon enters a tissue atom, interacts with an orbital electron(generally a middle or outer shell electron) and removes it from its shell
Compton interactions
low energy X-ray photons
secondary photons
The process of outer shell electrons filling inner shell vacancies creating a cascading effect
Characteristic cascade
The interaction occurs when the incident x-ray photon has enough energy to escape interaction with the orbital electrons and interact with the nucleus of the tissue atom
pair production
The nucleus of the atom involved regains stability by ejecting a nuclear particle such as a photon, neutron, or alpha particle
Photodisintegration
The difference between the x-ray photons that are absorbed photoelectrically versus those who penetrate the body
Differential Absorption
Refers to those x-ray photons that pass through the body and reach the IR
transmission
Those photons that are attenuated by the body and do not reach the IR
Absorption
