CR Review #1

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

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

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

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

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

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

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

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

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

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)

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

This device converts analog data into digital data.

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

This means the general emission of light:

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