Figure 2From: A dosimetric phantom study of dose accuracy and build-up effects using IMRT and RapidArc in stereotactic irradiation of lung tumoursMeasured central doses of the tumours (Ø1.5 cm and Ø4.0 cm) with the calculated MUs of PBC and AAA. The dose prescription was 1.0 Gy to the centre of the mimicked tumour. The error bars represent the 95% confidence intervals of the measurements.Back to article page
