抄録

An optical interference-pattern, a moire artifact, is produced during the film scanning process using a flatbed scanner. Images with moire artifacts include optical density fluctuations thereby leading to inaccuracy of measurement. In this study, we proposed two methods for removing moire artifacts from radiochromic film and compared dose response and profile as well as image resolution and size between our proposed methods versus the conventional process. The proposed methods could remove the artifacts without impairing dosimetric performance. It is expected that the proposed methods facilitate more accurate film dosimetry with reflective radiochromic films.
