摘要：
Radiochromic film (RCF) has been applied to mapping of dose distributions in radiation therapy. However, this particular RCF product suffers from intrinsic nonuniform response. In this study, we have carefully measured the nonuniformity of unirradiated RCF and the response of irradiated RCF in pixel-to-pixel as function of various absorbed doses, in order to ascertains for the method of predicting the error of irradiated, unirradiated RCF.
