CR Exposure Indicator System

EI numbers are not able to distinguish between exposure amounts being from kVp or mAs

(T or F) Each manufacturer has their own system for the Exposure Indication.

(T or F) LgM numbers are typically 1.95 – 2.5

LgM stands for _____________.

(T or F) Properly exposed images should have an EI ranging from 1,700 – 2,200

Any changes by a factor of 2, will cause a_____ change in the LgM

S numbers are (Inversely or proportionally) related to the amount of exposure to the image receptor in mR

Kodak uses an exposure system, which is the (DI, EI, S or LgM ?) number

Outside the manufacturers ranges, an image is under or over exposed, regardless of appearance on screen

The Higher the LgM #, the ( more or less ) exposure.

(T or F) The EI Indicates how much radiation (or exposure) reached the receptor.

(T or F) Exposure of the CR plate to light will NOT increase density & may have a minimal impact on the image.

Changing your mAs by a factor of 2 will change the EI by _______.

Properly exposed IP should have S number of 15 - 25.

Changing your mAs by a factor of 2 (multiply or divide) will change the S# by a factor of _____.
