If the exposure is within the range 27.5 to 29.5 kVp, the
reading is accurate. If ---.kVp is displayed, set the
generator for 28 kVp and repeat step 4. If 0.0 kVp is
displayed, set the generator to 30 kVp and repeat step 4.
The k-edge kVp is used to determine linear filter pack
correction.
Once an accurate determination of kVp has been made do
not disturb the x-ray generator settings. Proceed to linear
mammo filter pack use.
Linear Measurement Setup:
Remove the k-edge filter pack and replace it with the
linear mammo filter pack. Increase the target to filter pack
distance to about 15 inches (38cm). If the Model
35080/A/B/M kVp Divider changes position in the x or y
axis with respect to the x-ray generator during the linear
kVp measurements, you must repeat the determination of
the k-edge kVp and the correction value since this
measurement is position sensitive.
Linear Correction Exposure:
Make an exposure using the same generator settings as
those used to make the last k-edge exposure. After this
measurement is complete, the kV correction for the linear
filter pack will be displayed. If you do not want your linear
kVp measurements automatically corrected, press F1
(LINEAR CHANGE…) and select No Correction. To
recalibrate the k-edge correction, select Recalibrate…
