Abstract: Systems and techniques may be used for radiotherapy. An example system may include a fixation device arranged to receive and immobilize a patient. The example system may include a first filter arranged to extend along a first portion (e.g., a spine or cranium) of the patient, the first filter attached to the fixation device at a first location, the first filter including a plurality of beam attenuating elements. The example system may include a fixed beam proton delivery system arranged to deliver a therapeutic proton radiation dose attenuated via the first filter to the first portion of the patient.

Abstract: Systems and techniques may be used for determining a line segment to be delivered from a particle beam towards a target. An example technique may include continuously scanning the particle beam at a constant rate from a starting point to an ending point, and determining a plurality of spots located between the starting point and the ending point. The technique may include determining a plurality of beamlets based on the plurality of spots, and determining, using an amount of dose to be delivered via each beamlet, a total amount of dose to be delivered. The technique may include generating a line segment having the starting point and the ending point, the line segment having the total amount of dose to be delivered based on the plurality of beamlets.

Abstract: Systems and techniques may be used to generate a radiotherapy treatment plan to execute using a particle beam from a continuously rotating gantry towards a target. A technique may include identifying a target location within a tumor of a patient, providing a particle beam configured to deliver radiotherapy treatment to the tumor along a trajectory using at least two energies including a first energy and a second energy, the first energy greater than the second energy, and determining a first location along the trajectory past the target location and a second location before the target location along the trajectory. The technique may include determining a configuration for the particle beam to deliver the first energy to the first location and the second energy to the second location. In some examples, a radiotherapy treatment plan according to the configuration may be output.

Abstract: Systems and techniques may be used for generating an image using one or more protons. For example, a technique may include detecting, over a time period using two orthogonal two-dimensional detector arrays, a magnetic field corresponding to a proton in motion. The technique may include determining a trajectory of the proton based on the magnetic field over the period of time, and generating a two-dimensional proton image using the trajectory. The two-dimensional proton image may be output for display.

Abstract: Techniques are described herein for delivering a particle beam from a continuously rotating gantry towards a target according to a determined patient state. The determined patient state and an identified gantry angle of a gantry may be used to deliver a set of beamlets (e.g., a pattern of radiation dose) to the target. The particle beam may rotate through a range of gantry angles. The set of beamlets may be delivered continuously while the gantry rotates.
