A radiophotoluminescent glass plate system for medium-sized field dosimetry

Abstract: A two-dimensional radiophotoluminescent system for medium-sized field dosimetry has been developed using a silver-activated phosphate glass plate with a dimension of 120mm×120mm×1mm and a readout unit comprising a UV excitation lamp and a CCD imager. A dose ranging from 0 to 400 cGy, provided by a 6 MV x-ray beam, was delivered to the glass plate oriented perpendicularly to the beam and positioned in a water phantom at a depth of 10 cm, where the center of the glass plate coincided with the linac isocenter.

“…This issue may be Elekta VMAT-specific because the machine parameters such as gantry speed and dose rate are automatically modified in the linac controller when delivered MUs are reduced. A solution may be to use a radiophotoluminescent glass plate with a linear dose response of up to 30 Gy [ 15 ].…”
