CR Review #2

Distance exists between the surface of the plate & the PM tube results in (increase or decrease) in resolution?

(T or F) High(er) kVp values can be used in CR imaging, as long as the technologist stays within the penetration range.

The thinner the phosphor layer; the (higher or lower) the image resolution.

It is suggested grid frequencies (greater or less) than 150 lines per in. be used in CR imaging.

CR (digital) imaging, is said to have a (narrow or wide) dynamic range.

Quantum Mottle occurs from (too much or too low) of mAs.

The smaller the laser beam, the (greater or less) the resolution.

(T or F) It is not acceptable to select a body part or position different from that actually being performed simply because it looks better.

__________ a signal is the assignment of a numeric value to each light photon.

(T or F) Automatic rescaling means images are produced with uniform density & contrast regardless of the amount of exposure.

The number of bits per pixel, that define the shade of each pixel, is known as the ____ _______.

A wavy artifact caused by grid lines running parallel to the laser scanning motion is called:

The bit depth will be a factor in determining the quality, specifically the (density or contrast) of the image.
