Proton therapy for cancer treatment

The technique of proton-beam therapy has undergone re-birth over the past decade and should soon be a part of clinical practice for oncology. This post is about a recent Vision 20/20 paper by Smith, Medical Physics, Feb 2009, that overviews this technology and advocates pRoton therapy over pHoton therapy. The potential of this technology is clear and the future is very promising. I know this is not medical imaging, but it influences the field greatly.
