Performance of optically stimulated luminescence Al2O3 dosimeter for low doses of diagnostic energy X-rays

Entrance Skin Dose (ESD) and Bucky Table Induced Backscattered Dose (BTI-BSD) in Abdominal Radiography With nanoDot Optically Stimulated Luminescence Dosimeter (OSLD)

“…Several other factors that need to be included are tube output, tube voltage, tube loading, focus-to-skin distance, and backscatter factors [18,19]. [34,49,50]. Also, the difference in ESD may be caused by several things, such as differences in patient weight and exposure factors [52,53].…”

“…This study utilized the nanoDot OSLDs while the other published data obtained the ESD values using different dosimeters, e.g., dose area product (DAP). Endo et al, Al-Senan and Hatab, and Lim et al were able to effectively evaluate how OSLDs (nanoDots) responded to x-rays in the diagnostic energy range [ 34 , 49 , 50 ]. With an average signal loss of less than 2.5% over the course of three repeated readouts, it is found that the nanoDots demonstrate high linearity and repeatability in the chosen radiation quality [ 51 ].…”

Studies done by Endo et al, Al-Senan and Hatab, and Lim et al have also looked at the dosimetric properties of OSLDs and found that they work well in the diagnostic energy range of 40-140 kVp [ 34 , 49 , 50 ]. Also, the difference in ESD may be caused by several things, such as differences in patient weight and exposure factors [ 52 , 53 ].…”

Image reconstruction algorithm for optically stimulated luminescence 2D dosimetry using laser-scanned Al2O3:C and Al2O3:C,Mg films

“…Optically stimulated luminescence (OSL) is now an established technique in personal dosimetry (Bøtter-Jensen et al 2003) and of increasing interest for medical physics applications, including remote dosimetry of therapeutic beams (Homnick et al 2008, Aguirre et al 2009, Dunn et al 2013, in vivo dosimetry in radiotherapy (Mijnheer et al 2013, Tanderup et al 2013, ion beam dosimetry (Sawakuchi et al 2010, Kerns et al 2012, Granville et al 2014, Yukihara et al 2015, as well as organ, phantom, surface dose and dose profile measurements in diagnostic radiology and fluoroscopy (Bauhs et al 2008, Lekovic et al 2008, Ruan et al 2010, Al-Senan and Hatab 2011, Endo et al 2011, Lim et al 2011, Al-Senan et al 2012, Funaga et al 2012, Vrieze et al 2012, Brunner et al 2013, Endo et al 2013, Giaddui et al 2013, Zhang et al 2013. Some of the intrinsic advantages of the technique are the optical readout, low background signal, wide dynamic range, re-readability, and precision (Yukihara et al 2014).…”
