Abstract: The embodiments of the present disclosure relate to a method and system for controlling the extraction of ion beam pulses produced by a synchrocyclotron. The synchrocyclotron comprises electrodes configured to be placed in a magnetic field. An alternating voltage is applied between the electrodes, and the frequency of the alternating voltage is modulated in a cyclic manner. In other embodiments, the method further comprises the steps of starting an acceleration cycle of the synchrocyclotron, generating a reference signal when the modulated frequency reaches a predefined value, communicating the time, at which the reference signal is generated, to the beam control elements, assessing one or more status parameters of the one or more beam control elements, and cancelling or proceeding with the extraction of the beam pulse depending on the results of the assessment.

Abstract: The present disclosure relates to an apparatus including a hadron therapy device and a magnetic resonance imaging device (MRI). The MRI may be an open MRI for acquiring magnetic resonance data in an MRI imaging volume. A nozzle of the apparatus may be fixed and positioned for directing a beam along a beam path substantially along an axis or substantially perpendicularly to the axis. The apparatus may further include a patient support system adapted for supporting a patient in a non-supine position in the MRI. The present disclosure also relates to methods for adapting a treatment plan to movements of organs resulting from displacement of a patient from a supine position in which treatment plan imaging was performed to a non-supine position in which a treatment will be performed.

Abstract: Disclosed embodiments include an energy degrader for attenuating the energy of a charged particle beam and comprising two energy attenuation members having different masses. The degrader further comprises a drive unit configured to move simultaneously the two energy attenuation members at respectively a first and a second speed across the particle beam during a first movement and to move the lightest of the two energy attenuation members at a third speed across the particle beam during a second movement, the third speed being higher than the first speed. More accurate and faster variation of the energy of the charged particle beam can hence be achieved.

Abstract: Disclosed embodiments include an energy degrader for attenuating the energy of a charged particle beam. The energy degrader may include a first energy attenuation member presenting a annular beam entry face and a continuous helical beam exit face, a second energy attenuation member presenting a continuous helical beam entry face and an annular beam exit face. The first and second helical surfaces may face each other. The energy degrader may also include a drive assembly configured for rotating the first and the second energy attenuation members around respectively a first axis and a second axis which are parallel to each other. The degrader may have a small moment of inertia, allowing more accurate and faster variation of the beam energy.
