  1. mA has what realationship with density?
    Directly proprotional
  2. Time has what relationship with density?
    Directly proprotional
  3. KVP has what relationship with density?
    A direct relationship according to the 15% rule
  4. SID has what relationship with denisty?
    Inversely squared proportional according to the inverse square law, because the intensity of the beam is inversly proportional to the square of the distance.
  5. IR speed has what relationship with denisty?
    directly proprotional
  6. Grid ratio has what relationship with denisty?
    inverse relationship, according to the grid ratio
  7. OID has what relationship with denisty?
    Inverse relationship, air gap technique
  8. Field Size has what relationship with denisty?
    direct relationship, as field size decreases, density decreases
