[2] IP exposure/dose measurement
SUPPLEMENTARY NOTE
Measure the dose at the center of the IP sensitivity calculation area and its outside beforehand
to calculate the ratio between them, and then determine the correction dose value according to
the calculated ratio.
(1) While exposing the IP with the center of the X-ray exposure aligned to the center of the
IP sensitivity calculation area, measure the dose with a dosimeter.

(2) Determine the correction dose value by rounding the dosimeter reading (in mR) to two
decimal places.
