Abstract: Systems for treating a patient using protons include a proton source configured to provide a proton beam having a plurality of proton energies and at least one processor. The at least one processor is configured to control relative movement between the proton beam and the patient in two dimensions, and to control the proton energy distribution to adjust the penetration depth of the protons in the third dimension while maintaining substantially fixed coordinates in the other two dimensions. Such treatment systems allow for shorter treatment times, higher patient throughput, more precise treatment of the desired areas, and less collateral damage to healthy tissue.

Abstract: Systems for generating a proton beam include an electromagnetic radiation beam (e.g., a laser) that is directed onto an ion-generating target by optics to form the proton beam. A detector is configured to measure a laser-target interaction property, which a processor uses to produce a feedback signal that can be used to alter the proton beam by adjusting the source of the electromagnetic radiation beam, the optics, or a relative position or orientation of the electromagnetic radiation beam to the ion-generating target. By adjusting the laser-target interaction, the feedback can be used to control properties of the proton beam, such as the proton beam energy or flux. Such systems have certain advantages, including reducing the size, complexity, and cost of machines used to generate proton beams, while also improving their speed, precision, and configurability.

Abstract: Systems for generating a proton beam include an electromagnetic radiation beam (e.g., a laser) that is directed onto an ion-generating target by optics to form the proton beam. At least one processor is configured to control the source of the electromagnetic radiation and the optics to alter the energy, polarization, spatial profile, and/or the temporal profile of the electromagnetic radiation beam, and to adjust the flux and/or energy of the proton beam. In some instances the system may adjust the proton beam energy while holding the proton beam flux substantially constant, or alternatively adjust the proton beam flux while holding the proton beam energy substantially constant. In other instances the system may adjust the proton beam energy while varying the proton beam flux, and/or adjust the proton beam flux while varying the proton beam energy.

Abstract: Disclosed are systems and methods for generating a beam of charged particles, such as an ion beam. Such a system may comprise an interaction chamber configured to support a target, one or more electromagnetic radiation sources, a sensor, and at least one processor. The one or more electromagnetic radiation sources may be configured to provide a probe beam at a first energy for determining orientation data of the target and a particle-generating beam at a second energy, which is greater than the first energy, for producing a beam of charged particles. The processor may be configured to receive feedback information from the sensor and to cause a change in a relative orientation between the particle-generating beam and the target.
