In ______ scattering, the incident x-ray interacts with a target atom, causing it to become excited. The target atom immediately releases this excess energy as a scattered x-ray with wavelength equal to that of the incident x-ray
_______scattering occurs between moderate-energy x-rays and outer-shell electrons. It results in ionization of the target atom, a change in x-ray direction, and a reduction in x-ray energy. The wavelength of the scattered x-ray is greater than that of the incident x-ray.
Compton scattering _____ image contrast.
X-rays in the diagnostic range also undergo ionizing interactions with inner-shell electrons. The x-ray is not scattered, but it is totally absorbed. This process is called the _____effect
what is the interaction called
A photoelectric interaction _____ occur if the incident x-ray has energy equal to or greater than the electron binding energy
The x-ray interacts with the nuclear field, and two electrons that have opposite electrostatic charges are created this is called _____
Differential absorption ______as the kVp is reduced
To image small differences in soft tissue, one must use ___ kVp to get maximum differential absorption
clinical x-rays are _______. They are emitted over an entire spectrum of energies.
The total reduction in the number of x-rays remaining in an x-ray beam after penetration through a given thickness of tissue is called 1-
