The conductor layer within the computed radiography (CR) imaging plate is
responsible for which of the following? Answer - Decreasing electrostatic
charge
Which layer of the computed radiography (CR) imaging plate prevents
unwanted light and background radiation from affecting the unprocessed latent
image? Answer - Light shield layer
Which layer of the computed radiography (CR) imaging plate is responsible for
creating the latent image from the transmitted x-ray photons exiting the
patient? Answer - Phosphor layer
The phosphor layer of the computed radiography (CR) imaging plate is
composed of: Answer - Barium fluorohalides and europium activators
The term "latent image" is used to describe the: Answer - Stored energy within
