Development of Radiation Dose Calculation Software Using the Size-Specific Dose Estimate

Abstract

We aimed to develop a software for facilitating absorbed dose per pixel (pixel dose) calculation using a size-specific dose estimate (SSDE). We calculated the pixel dose at nine equal points inserted into the radiophotoluminescence glass dosimeter (RPLD) and compared the pixel dose with the measured doses using RPLD. With this method, the relative errors of average pixel dose was -0.1% for adults and 2.86, 3.36 and 1.17% for those aged 10, 5 and 1 years without tube current modulation, respectively. In contrast, the relative error of SSDE was 17.37% for adults and 20.38, 20.73 and 19.20% for those aged 10, 5 and 1 years, respectively. In other words, the pixel dose was almost equal to the measured doses. Therefore, our software can be useful for determining arbitrary point.

“…Further dose packages have subsequently become available based on other sets of normalized organ dose data (see, for example, (Kalender et al 1999); (Schmidt and Kalender 2002); (Stamm and Nagel 2002); (Lee et al 2011); (Ban et al 2011); (Kalender 2014); (Sahbaee et al 2014); (Lee et al 2015); (Ding et al 2015); (Schmidt et al 2015); (Cros et al 2017); (Guberina et al 2017) and (Adrien et al 2020)). In addition, dose information has been calculated in relation to patient-specific dosimetry (see, for example, (DeMarco et al 2007); (Deak et al 2008); (Turner et al 2011); (Zhang et al 2012); (Shohji et al 2018); (Sharma et al 2019); (Akhavanallaf et al 2020)) and to tube current modulation (see, for example, (Schlattl et al 2010); (Stratis et al 2013); (Khatonabadi et al 2013); (Li et al 2014); (Kawaguchi et al 2015); (Bostani et al 2015); (Tian et al 2015); (Tian et al 2016); (Sookpeng et al 2016); (Bostani et al 2017); (Fujii et al 2017)).…”
