Techniques for particle beam therapy

A non-transitory computer-readable medium carrying one or more sequences of instructions for execution by one or more processors, wherein execution by the one or more processors causes the one or more processors to:

• receive first data indicating a plurality of target volumes within a target region inside a subject for particle therapy, the first data indicating the plurality of target volumes relative to a particle beam outlet on a gantry for directing a particle beam from the particle beam outlet;
• move automatically one or more energy modulator components of an energy modulator device disposed between the particle beam outlet and the subject, to reduce an energy of the particle beam such that a Bragg Peak is delivered to at least one target volume of the plurality of target volumes;
• repeat the step of moving automatically the one or more energy modulator components as the particle beam outlet rotates with the gantry around the subject without changing energy of the particle beam at the particle beam outlet until every target volume is subjected to a Bragg Peak;
• and
• initiate a vibrating component to vibrate the one or more energy modulator components during a delivery of a plurality of particle beams to a target volume to spread depth of the Bragg Peak over at least a subset plurality of target volumes of the plurality of target volumes.

A system for particle therapy comprising:

• a gantry with a particle beam outlet for directing a particle beam;
• an energy modulator comprising one or more energy modulator components disposed between the particle beam outlet and a subject;
• a vibrating component configured to vibrate the one or more energy modular components;
• and
• at least one processor;
• and
• at least one memory including one or more sequences of instructions,
• the at least one memory and the one or more sequences of instructions configured to, with the at least one processor, cause the system to perform at least the following,
• receive first data indicating a plurality of target volumes within a target region inside the subject for particle therapy, the first data indicating the plurality of target volumes relative to the particle beam outlet;
• move automatically the one or more energy modulator components of the energy modulator, to reduce an energy of the particle beam such that a Bragg Peak is delivered to at least one target volume of the plurality of target volumes;
• repeat the step of moving automatically the one or more energy modulator components as the particle beam outlet rotates with the gantry around the subject without changing the energy of the particle beam at the particle beam outlet until every target volume is subjected to a Bragg Peak;
• and
• initiate the vibrating component to vibrate the one or more energy modulator components during a delivery of a plurality of particle beams to a target volume to spread depth of the Bragg Peak over at least a subset plurality of target volumes of the plurality of target volumes.
