Figure 4-30. Set up for 80 kVp (base at six inches).
4-37. EVALUATION AND INTERPRETATION
a. Measure each film at a reference point.
b. Record the data on the appropriate area of the form.
c. If the kVp is constant, the exposure time should increase with the increased
d. If the phantom thickness remains the same, the exposure time should
decrease with the increased kVp.
Densities should be in the range of 0.4 optical density over the kVp for a
phantom thickness above four inches.
