Imaging

Review

Name How Image is Created What grayscale means Full thickness?

Radiography utilizes high

frequency EM rays

Radiographic penetrance is dependent on two variables: 1.) 2.)

Tissue Thickness

Tissue Thickness

Tomato B was cut in half, because it is darker, and therefore thinner

Tissue Density

MORE Dense, therefore absorbing more X-Rays, therefore less is transmitted, therefore the radiographic film is read as white LESS Dense, therefore absorbing fewer X-Rays, therefore more is transmitted, therefore the radiographic film is read as black

Tissue Density

MORE Dense, therefore absorbing more X-Rays, therefore less is transmitted, therefore the radiographic film is read as white Radiopaque LESS Dense, therefore absorbing fewer X-Rays, therefore more is transmitted, therefore the radiographic film is read as black Radiolucent
