Film Radiography

Emulsion in the context of film composition refers to:

• The light-sensitive (or x-ray sensitive) layer on photographic film

• A type of camera lens

• A method of editing film

• A style of film lighting

The base of the film is a ______ sheet to support the emulsion and is ______.

• Polyester, Translucent

• Plastic, Opaque

• Glass, Transparent

• Paper, Colored

The role of a Developer in film processing is to:

• Convert the latent image into a visible image

• Fix the image permanently on the film

• Remove unexposed silver halide crystals

• Add color to the film

The function of a Fixer in film processing is:

• to remove unexposed silver halide from the film

• to develop the latent image on the film

• to stop the development process

• to add color to the film

Density in image characteristics refers to:

• The degree of darkness or lightness in an image

• The sharpness of the image edges

• The number of colors in an image

• The size of the image file

A Characteristic Curve in imaging is:

• a graph showing the relationship between exposure and density in an imaging system

• a curve representing the color spectrum of an image

• a chart showing the resolution of an imaging system

• a diagram of the physical structure of an x-ray tube

Contrast in image characteristics refers to:

• The difference in brightness between the light and dark areas of an image.

• The sharpness of the edges in an image.

• The number of colors present in an image.

• The size of the image.

Speed in the context of image characteristics refers to:

• The sensitivity of the image sensor or film to light or x-rays

• The sharpness of the image

• The color accuracy of the image

• The resolution of the image

A faster speed film will require _____ radiation than a slower speed film to provide similar optical density.

• more

• less

• the same amount

Latitude in image characteristics refers to:

• The range of exposure that produces acceptable results

• The sharpness of the image

• The color balance of the image

• The resolution of the image
