    J Appl Clin Med Phys 15:4721. 2014
    ..These observations, based on the 40 separate curves that were calculated, should help the medical physicist at any new proton therapy facility in deciding which considerations are worth particular attention. ..

    Christopher G Ainsley
    Department of Radiation Oncology, University of Pennsylvania, Philadelphia, PA 19104, USA
    Phys Med Biol 58:N145-55. 2013
    ..Our technique is simple to implement, robust in nature and also provides insight allowing parameters that must be contrived in that model to be related directly to physical aspects of the beam delivery system...

    Phys Med Biol 58:6193-204. 2013
    ..Integration of these dose kernels from 0 to 40 mm radius shows that the charge deficit in the Bragg peak chamber varies <2% from entrance to the end of range for energies <180 MeV, but exceeds 5% at 225 MeV...

    Phys Med Biol 59:493-504. 2014
    ..Though the one-dimensional distributions are similar for the primary and tail components at different positions, the primary components of the DN spots are more elliptical 270 mm upstream than at isocentre...
