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: Embodiments of the present disclosure are directed to radiotherapy systems. An exemplary radiotherapy system may comprise a radiotherapy output configured to deliver a charged particle beam to a patient. The system may also comprise a detector array. The detector array may have an axis that extends parallel to an axis along which the charged particle beam is delivered by the radiotherapy output. The detector array may comprise a plurality of detectors configured to detect a magnetic field generated by the charged particle beam during delivery of the charged particle beam from the radiotherapy output.

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.

Abstract: Techniques are described herein for delivering a particle beam composed of a plurality of beamlets from a continuously rotating gantry towards a target, by determining a plurality of predefined spots on the target and configuring them into a set of smaller spots on the outside of the target and a set of larger spots on the inside of the target, optimizing the delivery of the rotating particle beam such that the inside edge and the outside edge of the arc of the rotating beam are delivered to the spots located at the center of the target, and the central component of the arc of the beam is delivered to the spots located at the outside of the target.
