This study uses Monte Carlo simulation and experimental measurements to develop a predictive model for estimating the external dose rate associated with permanent radioactive source implantation in prostate cancer patients. The objective is estimate accuracy of patient’s measurement. First, I-125 sources were implanted into Mylar window water phantoms simulate these Water phantom measurement was combined equations, whose performance verified against clinical data. model’s predicting patients...
This paper discusses the feasibility of a monitoring program for quality assurance status activity meters. We sent questionnaire to clinical nuclear medicine departments medical institutions, requesting information on their meters and practices. On-site visits were conducted with exemption-level standard sources (Co-57, Cs-137 Ba-133) dose calibrators in including physical inspection, accuracy reproducibility. A method offering quick check detection efficiency space dimension inside was also...
Transmission-target x-ray tubes generate more x-rays than reflection thick-target tubes. A transmission tube combined with radiosensitizers has a better radiation enhancement effect. This study investigated the feasibility of using in clinical radiotherapy and its effect on dose enhancement.This used MCNP6.2 to simulate model Co-60 beam. The was examined iodine-127 (I-127), radioiodinated iododeoxyuridine (IUdR), gold nanoparticles (GNPs).The results showed that factor (DEF) GNPs 10.27,...
Abstract This study discussed comparing result accuracy and time cost under different tally methods using MCNP6 for a novel transmission X-ray tube which was designed the Auger electron yield with specific material (eg. iodine). The assessment included photon spectrum, percent depth dose, mass-energy absorption coefficient corresponding to air water, figure of merit comparison. mean energy in-air phantom from 41.8 keV (0 mm) 40.9 (100 mm), in-water 41.41 45.2 mm). dose conversion factors...
Summary Soft ground is often improved to increase strength and stiffness by jet grouting method which results in heterogeneous with columns. Conventional testing methods used assess such improvement are subjected several limitations as small sampling volume, time-consuming, cost ineffectiveness. It's difficult the average property of actual replacement ratio improvement. The use seismic surface wave (i.e. multi-station analysis wave, MASW) for a purpose seems be good candidate. But...
There are two types of X-ray devices: transmission-type and reflection-type. These rely on different principles to generate X-rays. This study aimed explore physical characteristics the newly developed anode device. The device (NanoRay Biotech) was assessed, beam quality determined by measuring half-value layer (HVL) energy spectrum. Furthermore, this measured percentage depth dose (PDD) flatness symmetry using ionization chambers in PTW MP3-s water tank, discussed stability linearity tube...
