Diagnostic filtration is principally employed to reduce the number of:1)  Low energy photons reaching the skin surface2)  Short wavelength photons reaching the skin surface3)  Scattered photons reaching the image receptor

An increase in filtration has what effect on contrast?

What characteristic of the x-ray beam is influenced by changes to the source-to-image distance (SID)?

The three primary geometric factors affecting image quality are ________________________.

Increasing the distance from the x-ray source results in:
