The setup picture of in-vivo dosimetry for patient 2. NanoDot™ optically stimulated luminescent (OSLD) dosimeters (Landauer Inc., Glenwood, IL) were used to measure the irradiated dose. The 15 × 15 cm2 cone was used to irradiate the target which size was 10 cm (superior-to-inferior) × 11 cm (Anterior-to-inferior). OSLD3 and OSLD4 are numbered 1 and 2 in the figure. OSLD3 and OSLD4 were located at the 2 cm and 3 cm from the isocenter, respectively
