5.4 Corrections

If the amount of molybdenum filtration were known, the correction could be made with the correction
curves in Figures 5-1 and 5-2. Figure 5-1 shows the correction required for total molybdenum filtration of
12 microns, 24 microns, and 35 microns (no correction is required for 24 microns). Figure 5-2 shows the
effect of adding 0.25 mm Al to the 24 microns of molybdenum.

























Figure 5-1.

Correction Curves for 12, 24, and 35 Microns Molybdenum Filtrations


A machine with 35 microns of molybdenum and a reading of 29.0, add 1.0 kV; the corrected reading is
30.0 kVp (Refer to Figure 5-1). For 12 microns and a reading of 28.0 kVp, subtract 1.5 kV for a corrected
reading of 26.5 kV.
