摘要： Embodiments of systems, devices, and methods relating to a beam system. An example beam system includes a charged particle source configured to generate a beam of charged particles, a pre-accelerator system configured to accelerate the beam, and an accelerator configured to accelerate the beam from the pre-accelerator system. The pre-accelerator system can cause the beam to converge as it is propagated from the source to an input aperture of the accelerator. The pre-accelerator system can further reduce or eliminate source disturbance or damage caused by backflow traveling from the accelerator toward the source.

摘要： Disclosed herein is a radiation head for a radiotherapy device. The radiation head comprises a source of radiation configured to emit a beam of radiation; and beam shaping device for collimating the beam of radiation. The beam shaping device comprises a multi-leaf collimator; and a diaphragm positioned between the source and the multi-leaf collimator. The diaphragm comprises a diaphragm block movable along a curved path, the diaphragm block having a flat face focused on a focus point which is offset from the source of radiation.

摘要： An example computer-implemented method for tuning a beam spot in a radiation therapy system based on radiation field measurements has been disclosed. The example method includes configuring an electron beam to generate a first beam spot (302) on an electron-beam target (303) of the radiation therapy system, determining a value for one or more radiation field quality metrics for a first radiation beam (230) that originates from the first beam spot, and based on the value, determining whether the first radiation beam is outside a specified quality range.

摘要： A particle therapy system that is adapted to irradiate a target volume (1) with charged particles in compliance with a desired 3-D dose distribution. Such a desired 3-D dose distribution is achieved while delivering a plurality of particle energy distributions at the output of an energy- shaping device (10) crossed by an incident mono-energetic charged particle beam (6). The energy-shaping device comprises a plurality of groups (12, 22) of energy-shaping elements (11, 21), each of them comprising an individual layer of fluid or solid material (13), which thickness is adapted individually by a control unit (14). The use of configurable layers of fluids or solid materials makes the energy-shaping device reusable for treating different patients.
