SU‐E‐T‐163: Thin‐Film Organic Photocell (OPV) Properties in MV and KV Beams for Dosimetry Applications

Abstract

With proper calibration, the OPV cells could be used for online radiation dose measurement for quality assurance and patient safety purposes. Their response to kV beam show promising potential in development of low cost kV radiation detection devices.

Technical Note: Nanometric organic photovoltaic thin film detectors for dose monitoring in diagnostic x‐ray imaging

“…Kingsley et al 4 used OPVs exposed to 6 MV clinical beams and found that these devices have sensitivities of an order of magnitude greater than a commercial silicon detector. Separately, Ng et al 5 investigated the dosimetric properties of thin film OPV cells for various irradiation conditions in medical applications of x-rays. The response of these cells was determined for different thicknesses and sizes and was found to be linear with dose and cell size, and slightly decreasing with the thickness of the active layer.…”
