To proceed with the decommissioning of Fukushima Daiichi Nuclear Power Station, it is necessary to visualize radioactive substances using a gamma camera in high-dose-rate regions inside nuclear reactor building. We developed an umbrella-shaped Compton camera, whose sensitivity distribution can be adjusted by changing its shape. When used on robot, moving distance robot reduced compared pinhole ...

background: the effectiveness and safety of brachytherapy treatment is mainly concerned with the calibration of sources and their traceability to internationally accepted standards. secondary standard dosimetry laboratory (ssdl) does not offer calibration of ionization chambers with gamma-ray spectrum of high dose rate source 192ir . this work has been carried out to calibrate the high dose rat...

PURPOSE High-dose-rate (HDR) brachytherapy plays a potential curative role in the treatment of prostate cancer. An expert panel was convened to review the recent literature and reach a consensus on its appropriate clinical applications. METHODS AND MATERIALS The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are revie...
