TLDR
A new spot beam scanning system was constructed for a 70 MeV proton beam and has been confirmed to be satisfactory for delivering a protonbeam in the desired field shape and dose level.Abstract:
In order to provide a uniform and desirable dose distribution over a large radiation field, spot beam scanning is one of the most useful methods. A new spot beam scanning system was constructed for a 70 MeV proton beam. The lateral dose distribution was uniform with +/- 2.5% for an 18 cm square field. It was possible to control the dose at each point in the radiation field by this spot scanning method. This system has been confirmed to be satisfactory for delivering a proton beam in the desired field shape and dose level.read more

Intensity modulation methods for proton radiotherapy.
TL;DR: It is concluded that the 3D method provides the greatest flexibility for constructing conformal doses in challenging situations, but that when large numbers of beam ports are available, little advantage may be gained from the additional modulation of intensity in depth.

TL;DR: Field specific dosimetry shows that these treatments can be delivered accurately and precisely to within +/-1 mm (1 SD) orthogonal to the field direction and to within 1.5 mm in range, indicating the flexibility of the spot scanning system for treating lesions of all types and sizes.
