Shuttering removes the dark exposed border, reducing the amount of information to be stored.

Changing the slope of the look-up table graph will increase or decrease:

The image reader scans and reads the image from the:

The process of joining two or more images into one continuous image is known as image:

Suppressing frequencies in the areas of interest is known as:

Image aliasing is similar to the moiré effect caused by grid error.

Data collected within the collimator are represented by a:

Proper patient demographic input is the responsibility of the:

A wraparound image or image aliasing occurs when:

If the entire range of exposure were digitized, pixel values representing ______ would be digitized.

Failure of the reader to find the collimation edges of an image:

The workstation function that allows selection of preset terms or manual text input is termed image:

Window width controls the ratio of black and white, also known as:

A look-up table is not used as a reference to:

If all of the shades were left in an image after processing, the contrast would be:

Low-pass filtering is also known as:

The Nyquist theorem states that the:

In an effort to display the pixels for the area of interest when exposure is greater or less than what is needed to produce an image, ______ occurs.

The longer an image is stored in the computed radiography (CR) cassette, the:

Automatic rescaling can be substituted for appropriate technical factors.
