Treatment fields can be produced as part of a treatment plan that achieves a desired balance between field delivery time and dose based on machine parameters and knowledge, such as machine-specific beam production, transport and scanning logic, and/or a maximum treatment time value. The treatment parameters can be adjusted using a graphical user interface so that treatment time or dosimetry is prioritized. As a result, the overall treatment time is reduced, and hence treatment quality and patient experience are improved.

System and method for radiotherapy field delivery time optimization

In various embodiments, a radiation therapy method can include loading a planning image of a target in a human. In addition, the position of the target can be monitored. A computation can be made of an occurrence of substantial alignment between the position of the target and the target of the planning image. Furthermore, after the computing, a beam of radiation is triggered to deliver a dosage to the target in a short period of time (e.g., less than a second).

Triggered treatment systems and methods

A beam transport assembly conveys a particle beam from a particle source to an irradiation nozzle, which rotates about a swivel axis at the horizontal input of the nozzle. A support can move horizontally in a plane perpendicular to the swivel axis. The beam transport assembly can change a path length of the particle beam so as to follow a vertical location of the swivel axis of the irradiation nozzle with respect to the support. A controller can coordinate the path length change of the particle beam, rotation of the irradiation nozzle about the swivel axis, and/or horizontal motion of the support to provide irradiation of a supported object from various angles in the plane perpendicular to the swivel axis while maintaining the irradiation nozzle at a constant distance from the supported object.

Particle therapy systems, devices, and methods for beam transportation

Irradiation device for irradiating an irradiation object with heavy charged particles, comprising a support for the irradiation object, and an irradiation nozzle irradiating a charged particle beam towards the irradiation object, wherein the beam is deflected within the irradiation nozzle. The support for the irradiation object is moveable at least horizontally, and the irradiation nozzle is moveable at least vertically and rotatable around a nozzle swivel axis along which the particle beam enters into the irradiation nozzle.

Irradiation device and method

System and method for shaping the intensity profile of a radiation beam incident on a target volume. Embodiments according to the present disclosure include a multi-leaf collimator (MLC) capable of sharpening (e.g., 'trimming') a proton beam, the MLC having a reduced overall weight. Leaves of the MLC according to embodiments of the present disclosure have two regions of different density, where a high density region is proximal to a radiation beam so as to block a portion of the beam, and a lower density region provides structural integrity to the leaf while reducing overall MLC weight.
