Materials and methods: Fifteen patients underwent IGPBI. Three fiducial markers were placed in the tumour bed at the time of surgery. Daily orthogonal anterior/ posterior and lateral kV-images were taken before each fraction and compared with the digitally-reconstructed radiographs, both using bony landmarks and fiducial markers as reference. The Student's t test was used to detect a meaningful difference of 3 mm in between the two methods. Results: A total of 105 image-guided radiation therapy (IGRT) sessions were obtained. The mean superior/inferior, right/left, and anterior/posterior shifts obtained using the bony landmarks vs. the fiducial markers were 2 mm [standard deviation (SD) 10 mm] vs. 0 mm (SD 7 mm), 0 mm (SD 7 mm) vs. 1 mm (SD 4 mm), and 1 mm (SD 7 mm) vs. 0 mm (SD 5 mm), respectively. The mean shift differences in absolute value between the two methods, along the superior/inferior, right/left and anterior/posterior directions were 5 mm (p=0.001), 3 mm [p=not significant (ns)], and 3 mm (p=ns), respectively. Conclusions: Fiducial markers for IG-PBI increase set-up accuracy compared to the bony landmarks, in particular along the superior/inferior direction.
