Abstract
An advantage of the cyclotron in proton therapy is the continuous (CW) beam outputwhich reduces complexity and response time in the dosimetry requirements and beam controls.A CW accelerator requires isochronous particle orbits at all energies through theacceleration cycle and present compact isochronous cyclotrons for proton therapy reach only250 MeV (kinetic energy) which is required for patient treatment, but low for full ProtonComputed Tomography (pCT) capability. PCT specifications need 300-330 MeV in order forprotons to transit the human body. Recent innovations in nonscaling FFAG design haveachieved isochronous performance in a compact (~3 m radius) design at these higherenergies. Preliminary isochronous designs are presented here. Lower energy beams can beefficiently extracted for patient treatment without changes to the acceleration cycle andmagnet currents. Copyright © 2012 by IEEE.
