title: [A method for removing moiré artifacts from scanned images of radiochromic films: application to transmissive scanning].
abstract: Dose verification using radiochromic films may bring about moiré artifacts during the film scanning process using a flatbed scanner. A method for removing the moiré artifacts was already reported for reflective scanning. Recently, transmissive scanning using EBT2 films has played a major role for dose verification in intensity-modulated radiation therapy. It was found that placing a nonreflecting glass plate on the detector side could eliminate all the moiré artifacts for transmissive scanning.
