(a) US image of SOBP C-ions irradiation of a PVA/PFB PAM phantom @37 °C (1 Gy, 4 × 106 ND/ml, 312 MeV/u, 180 mm); the yellow arrow indicates the beam enteance side. (b) Comparison between SOBP and pristine Bragg peak irradiation of NDs post 1 Gy exposure. The shaded areas represent the standard deviations, n = 6).
