Abstract
Embodiments of the present invention describe systems and methods for providing proton therapy treatment using a beam line where the ESS is reduced or eliminated. For multi-room configurations, a beam line is included having quadrupole and steerer magnets to align and focus a particle beam extracted by an accelerator and guided by a bend section. A degrader is disposed between the bend section and the treatment room, and the energy analyzing functionality is performed by the gantry.

A modular multi-room treatment system comprising:
- N number of bend sections coupled to a beam transfer line, wherein the beam transfer line and N number of bend sections are operable to direct a particle beam from an accelerator to N number of treatment rooms;
- N number of degraders disposed between the N number of bend sections and the N number of treatment rooms, wherein the particle beam is focused on the N number of degraders to modulate an energy of the particle beam;
- and
- N number of gantries disposed in the N number of treatment room and operable to receive the particle beam downstream from the N number of degraders, wherein the N number of gantries provide energy selection functionality for the N number of treatment rooms.
A treatment system particle beam delivery method comprising:
- directing a particle beam from a particle beam source along a beam transfer line to N number of bend sections;
- aligning and focusing the particle beam on the N number of bend sections by the beam transfer line;
- directing the particle beam from the N number of bend sections to N number of degraders;
- degrading the particle beam by the N number of degraders to modulate an energy of the particle beam downstream of the N number of bend sections;
- and
- providing energy selection functionality of the modulated energy of the particle beam by N number of gantries disposed in N number of treatment rooms downstream of the N number of degraders.
