^Äëíê~Åí=cáëáÅá= =absorbed dose. The angular coefficient of 10 FFF straight line was different by 1,2% from 10 MV one. NanoDots angular dependence response presented a maximum deviation from the 0° angle reading of 5%, corresponding at 240° angle. A dose-rate dependence was found in the range 800- 2400 MU/min: 2% respect to reference dose rate (1200 MU/min). The results of the comparison Pin Point VS OSLD VS TPS are showed in the table. The Nanodot signal, caused by CBCT, was negligible (<1%) for high dose used in these cases.•• TPS Dose (Gy)• Pin point Dose (Gy)• OSLD Dose (Gy)• Deviation (%) OSLD - Pin Point• Lu ng• 29.7 1• 29.62• 30.22•2• Sp ine• 31.8 7• 32.13• 31.95• -0.56Table 1.ConclusionsThe OSLD exhibited to be feasible for SBRT treatments application.42
