Answer:

quantization

Question 22: kVp controls what?

Answer:

the energy or quality of xrays produced

detail Question 27: which of the following describes the relationship between radiographic density and the use of grids?

Answer:

grids reduce density unless mAs is increased to compensate

Answer:

increase OID=increase contrast
