CR Review #1

This device converts analog data into digital data.

The latent image will lose about ____% of its energy over about 8 hours time.

IP’s are very sensitive to scatter and should be erased how often? to prevent the buildup of any background signal (or if unsure of last use)

An IP is 'erased' via exposure to what color light ?

(T or F) CR systems are considered to be "Stimulated Phosphorescence"

What causes the electrons to be released from the F centers, within the phosphors of the CR IP ?

(T or F) To correct the elliptical shape of the laser, the beam is “shaped” by special optics that keep the beam size, shape, and speed largely independent of the beam position.

The distance between the midpoint of one pixel to the midpoint of an adjacent pixel describes the _____ _______.

The letters, PM as part of a PM tube stands for:

The movement of the laser across the imaging plate (vs the plate moving), is called:

The reader scans the plate with red light in a zigzag, or _______ pattern.

To digitize the analog signal from the PMT, it must first be _______.

(T or F) The CR latent image is considered to be 'trapped' electrons.

This means the general emission of light:

Increasing the sampling frequency results in a smaller sampling and pixel pitch, which (increases or decreases?) the spatial resolution of the digital image.

Contained within the IP Active layer, are the ____ _____ crystals.
