density

What is the controlling factor for density?

Which law states that density should remain the same with any combination of mA and time as long as your mAs is the same?

What percentage of change in mA will be needed to have a visible difference in density

T or F A 5% increase in KvP will cause a visible difference in density

SID and beam intensity have a _________ relationship

Film density will ____________as filtration is increased

T or F Grids have no Effect on density
True False

As tissue thickness and type increase density will

Will increasing collimation increase or decrease the total number of x-ray photons hitting the IR?

A grid is used to improve contrast by__________

Scatter increases and contrast is impaired as KvP

T or F Scatter decrease with increasing volume of tissue being radiated and decreases with increased atomic number of the tissue.

T or F a 12:1 gird ratio will absorb more scatter than an 8:1
True False

________ grids are commonly used because they allow tube angulations.

T or F A focused grid with lower grid ratios has a greater latitude than higher grid ratios
True False
