A system update method for a particle beam therapy system, includes: a step of providing a new beam transport system in such a manner as to be branched off from an existing beam transport system of the particle beam therapy system; and a step of providing new installation connected to the new beam transport system, in which the branch is provided in a linear section of the existing beam transport system.

Techniques for particle beam therapy include receiving a target region inside a subject for particle therapy, a minimum dose inside the target region, and a maximum dose inside the subject but outside target region. Multiple beam axis angles are determined, each involving a grantry angle and a couch position. Multiple spots within the target region are determined. For each beam axis angle a pristine particle scan beam (not coaxial with any other particle scan beam) is determined such that a Bragg Peak is directed to a spot, and repeated until every spot is subjected to a Bragg Peak or an intersection of two or more such pristine scan beams. Output data indicating the pristine beamlets is stored for operation of a particle beam therapy apparatus.

Described herein are methods for beam station delivery of radiation treatment, where the patient platform is moved to a series of discrete patient platform locations or beam stations that are determined during treatment planning, stopped at each of these locations while the radiation source rotates about the patient delivering radiation to the target regions that intersect the radiation beam path, and then moving to the next location after the prescribed dose of radiation (e.g., in accordance with a calculated fluence map) for that location has been delivered to the patient.

Disclosed herein is a method comprising: generating multiple radiation beams respectively from multiple locations toward an object and an image sensor, wherein the image sensor comprises an array of multiple active areas, and gaps among the multiple active areas, and capturing multiple partial images of the object with the image sensor using respectively radiations of the multiple radiation beams that have passed through and interacted with the object, wherein each point of the object is captured in at least one partial image of the multiple partial images.

An example method of treating a target using particle beam includes directing the particle beam along a path at least part-way through the target, and controlling an energy of the particle beam while the particle beam is directed along the path so that the particle beam treats at least interior portions of the target that are located along the path. While the particle beam is directed along the path, the particle beam delivers a dose of radiation to the target that exceeds one (1) Gray-per-second for a duration of less than five (5) seconds. A treatment plan may be generated to perform the method.

Systems and methods are described herein to provide a user-interface to visualize and control a beam request panel for requesting allocation of usage of a shared therapy beam. The user interface allows a user to visualize a beam request queue, to request the shared therapy beam for treatment, to estimate when a beam request will be fulfilled, and to cancel a beam request if needed.

A control system is described which provides a user interface that displays a clear graphical representation of relevant data for a particle radiation therapy system (such as a pencil-beam proton therapy system) for treating multiple beam fields as efficiently as possible. The user interface allows a user to visualize a treatment session, select one or multiple beam fields to include in one or more beam applications, and dissociate beam fields previously grouped if necessary. Further embodiments extend the ability to initiate the application of the generated proton therapy beam and the grouping of beam fields to be performed remotely from the treatment room itself, and even automatically, reducing the need for manual interventions to setup between fields.

Provided is an energy degrader including an attenuation member that becomes radioactive only to a lesser extent than conventional attenuation members. An attenuation member (11) is a graphite film, the graphite film has a thermal conductivity, in a surface direction, of 1200 W/(m.Math.K) or greater, and the graphite film has a thickness of 0.1 m or greater and 50 m or less.
