Research Abstract

We made a correction of dosimetry to clarify the physical charactaristics of MOSFET wireless dose meter using our original prostate phamtom and Ir-192 radiation source. Next, we planned to make a in vivo dosimetry to calculate the urethral and rectal dose of the patient treated with high-dose-rate brachytherapy for prostate cancer, but main researcher moved to another hosipital and we could not do that.
