摘要： Embodiments of the present invention describe systems and methods for providing radiotherapy treatment by focusing an electron beam on a target (e.g., a tungsten plate) to produce a high-yield x-ray output with improved field shaping. A modified electron beam spatial distribution is employed to scan the target, such as a 2D periodic beam path, which advantageously lowers the x-ray target temperature compared to the typical compact beam spatial distribution. As a result, the x-ray target can produce a high yield output without sacrificing the x-ray target life span. The use of a 2D periodic beam path allows a much colder target functioning regime such that more dosage can be applied in a short period of time compared to existing techniques.

摘要： 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).

摘要： A radiation system includes a radiation source providing therapeutic radiation, a first gantry supporting a second gantry carrying the radiation source. The first gantry is rotatable about a first axis passing through an isocenter, thereby allowing the radiation source to aim therapeutic radiation at a target volume from a plurality of locations in a first plane. The second gantry carrying the radiation source is rotatable about a second axis passing through the isocenter non-parallel with the first axis, thereby allowing the radiation source to aim therapeutic radiation at the target volume from a plurality of locations in a second plane non-coplanar with the first plane.

摘要： The present disclosure relates to a new scan technique for particle radiation therapy that may be used for cancer treatment. One embodiment relates to a method of mitigating interplay effect in particle radiation therapy in a moving target including a period of movement, where the particle radiation therapy defines a planned dose in each spot of each layer of the moving target. The method comprising dividing the planned dose in each spot into a number of spot repaintings; and generating a scan pattern for each layer by defining a beam-on time at each spot for each spot repainting, and calculating a wait time between consecutive beam-on times to distribute the spot repaintings for each spot of a respective layer are distributed over a duration of an integer number of periods of movement.

摘要： A phantom setup and source-to-surface distance (SSD) verification method uses radiation images. In an exemplary method, a phantom is positioned on a support relative to a radiation source such that a surface of the phantom is horizontally leveled at or approximate to a desired value of SSD. The radiation source is then positioned at a gantry angle predetermined at least based on the desired value of SSD such that a ray of radiation from the radiation source aligns with a horizontal surface located at the desired value of SSD. An image is acquired using radiation from the radiation source at the predetermined gantry angle. Verification is performed to confirm, based on an analysis of the image, if the surface of the phantom is positioned at the desired value of SSD.

摘要： 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.
