MOSkin detectors were studied to perform real-time in vivo dose measurements in high dose rate prostate brachytherapy. Measurements were performed inside an urethral catheter in a gel phantom simulating a real prostate implant. Measured and expected doses were compared and the discrepancy was found to be within 8.9% and 3.8% for single MOSkin and dual-MOSkin configurations, respectively. Results show that dual-MOSkin detectors can be profitably adopted in prostate brachytherapy treatments to perform real-time in vivo dosimetry inside the urethra.
研究了MOSkin探测器，以在高剂量率前列腺近距离放射治疗中进行实时体内剂量测量。测量在模拟真实前列腺植入物的凝胶体模中的尿道导管内进行。比较了测量剂量和预期剂量，发现单MOSkin和双MOSkin配置的差异分别在8.9%和3.8%以内。结果表明，双MOSkin探测器可有效地应用于前列腺近距离放射治疗，以在尿道内进行实时体内剂量测定。
