Proton therapy: IMPT goes clinical
Proton therapy today is delivered almost exclusively via passive scattering, in which the proton beam is spread out and then shaped to the target volume using customized collimators and compensators. Pencil-beam scanning, in which a narrow beam is scanned throughout the target volume, should improve dose distributions and increase sparing of proximal healthy tissue. Taking things a step further, we're now seeing the emergence of intensity-modulated proton therapy, or IMPT.
IMPT – defined as the simultaneous optimization of all Bragg peaks from all incident beams – could increase dose conformality even further. The technique, pioneered by researchers at the Paul Scherrer Institute in Switzerland, is now being offered commercially by Varian Medical Systems (Palo Alto, CA).
