Intro: Interactions with Matter Test Review

Front

Photon

Back

A unit of energy in a light ray.

Front

X-ray Photon Production

Back

X-ray photons are produced by accelerating electrons into a metal target.

Front

kVp (Kilovolt peak)

Back

A measure of the peak voltage applied to the x-ray tube.

Front

mAs (Milliampere-seconds)

Back

The product of current (mA) and exposure time (seconds), influencing patient dose and image quality.

Front

Patient Dose Factors

Back

Primarily determined by mAs.

Front

X-ray Interaction with Tissue

Back

X-rays can be absorbed, scattered, or pass through human tissue.

Front

Absorption

Back

Refers to energy transferred to tissue.

Front

Absorbed Dose (D)

Back

Energy absorbed per unit mass of tissue.

Front

Primary Radiation

Back

The x-ray beam directed toward the image receptor.

Front

Attenuation

Back

Decrease in intensity of x-rays due to absorption or scatter.
