Finally, 3DPB shields have been used during the treatment of seven patients' skin lesions. Results 10 and 15 mm of 3DPB were sufficient to shield 6 and 9 MeV electrons by 95%, respectively. The 3DPB and lead shields had nearly identical beam widths (within 1%). Output factors were on average within 0.8% for bronze shields and 1.2% for lead shields relative to an unshielded field. The skin enhancement for bronze was higher than for lead by an average of 6.3%. Phantom measurements using 3DPB shields generally showed less than 3
