The number of lead lines per inch or centimeter is:
 
 grid linearity
  grid frequency
  grid ratio
  grid efficiency

Question 2

The primary disadvantage of performing chest images with the AP projection rather than the PA is:
 
 distortion of the bony thorax

  increased technical settings for the patient
  increased magnification of the heart

Answer to Question 1

grid frequency

Rationale: Grid frequency is the number of lead lines per inch or centimeter.

Answer to Question 2

increased magnification of the heart

Rationale: Imaging chests with the PA projection is preferred as it positions the heart closer to the image receptor, reducing magnification. Heart size is certainly of importance and is included in radiologist dictation report.
