Proton dose distortions within uniform transverse magnetic field of 0.5 T (a), 1.5 T (b), and 1.5 T with delivery corrections (c), for a prostate plan (i.e. large range representing the worst-case scenario). d Dose volume histogram for the 3 above scenarios with the magnetic field on, compared to the planned dose with no magnetic field.
