Image Quality

______ is a process whereby some of the x-ray beam will be absorbed as well as pass through the anatomic part.

• Transmission

• Differential absorption

• Beam Attenuation

• Scatter

This is the reduction of energy of the primary beam as it passes through various anatomic tissues.

• Absorption

• Scattering

• Attenuation

• Transmission

When an incoming photon has sufficient energy to eject an inner – shell electron and be completely absorbed it is called_____

• Compton Scattering

• Characteristic interaction

• Photoelectric effect

• Bremsstrahlung Effect

Tissues composed of higher atomic numbers will increase beam attenuation

• True

• False

Higher kVp increases the energy of the x-ray beam and will increase beam attenuation

• True

• False

Together, _________ & __________ will provide an image that structurally represents the anatomic part.

• Absorption and scatter

• Absorption and transmission

• Transmission and scatter

Remnant or exit radiation is composed of _______ photons.

• Absorbed and transmitted

• Transmitted and scattered

• Absorbed and scattered

• Absorbed, Transmitted and Scattered

Increased brightness on the radiographic image are created by

• absorbed photons

• transmitted photons

Decreased brightness on the radiographic image are created by:

• Absorbed photons

• Transmitted photons

Attenuation may be defined as:

• interactions that only occur at doses used in radiation therapy.

• radiation that emerges from the patient.

• changes in the x-ray beam as it travels through the patient.

•  interactions that only produce scatter radiation.
