  • Patent number: 10124191
    Abstract: The invention relates to a hadron therapy installation that comprises an irradiation unit (1) supported by a rotary support structure, so as to be able to rotate around a target volume (15) centered on the axis of rotation (22), to deliver a treatment beam (17) from different angles on the target volume (15). An imaging device (3, 4) is secured in rotation with the irradiation unit (1) and translatable relative to the irradiation unit (1) between a retracted position at the irradiation unit (1) and a lateral deployed position relative to the target volume (15), such that in its deployed position, the imaging device (3, 4) can rotate around the target volume (15) together with the irradiation unit (1). Such an installation can be used for a cone beam computed tomography method and/or a fluoroscopic imaging method on a patient to be treated in the hadron therapy installation.

  • Patent number: 9789343
    Abstract: The present disclosure relates to an accessory holder attachable to or integrated in the nozzle of an apparatus for particle beam irradiation treatment. The accessory may be an aperture piece, a range shifter or any other element that can be placed in the beam path between the outer end of the nozzle and the irradiated target. The accessory holder may be equipped with first displacement means for moving the accessory away from or towards the nozzle, thereby moving the accessory forwards and backwards in the direction of the beam and second displacement means for moving the accessory into or out of the beam path. Measurements or treatment steps may be performed with and without the accessory in the beam path, without interrupting the treatment.

  • Patent number: 9302123
    Abstract: A gantry structure (16) designed for pivoting about an axis of rotation (18) and for delivering a hadron beam on a target comprises a beam delivery line (24) receiving the hadron beam in a direction essentially parallel to the axis of rotation (18), deviating it away from said axis of rotation (18) and delivering it so that the axis of the beam intersects the axis of rotation (18). The beam delivery line (24) is a self-supporting structure supported by a pivotable support arm (32) in proximity of the center of gravity of the beam delivery line (24). A counterweight (42) is supported by a support arm extension (40) on the other side of the axis of rotation (18) for compensating the moment of force due to the weight of the beam delivery line (24) and the support arm (32).

  • Patent number: 9237640
    Abstract: RF device (1) able to generate an RF acceleration voltage in a synchrocyclotron. The device comprises a resonant cavity (2) formed by a grounded conducting enclosure (5) and enveloping a conducting pillar (3) to a first end of which an accelerating electrode (4) is linked. A rotary variable capacitor (10) is mounted in the conducting enclosure at a second end of the pillar, opposite from the first end, comprising at least one fixed electrode (stator) (11) and a rotor (13) exhibiting a rotation shaft (14) supported and guided in rotation by galvanically isolating bearings (20), said rotor (13) comprising one moveable electrode (12) possibly facing the stator (11). When the shaft (14) rotates, the stator and the moveable electrode together form a variable capacitance whose value varies cyclically with time. The rotor (13) is galvanically isolated from the conducting enclosure (5) and from the pillar (3). The stator (11) is connected to the second end of the pillar (3) or to the conducting enclosure (5).

  • Patent number: 8223920
    Abstract: The present invention is related to a patient positioning imaging device for positioning a patient in a hadron therapy device provided with a rotatable gantry (20). The patient positioning imaging device comprises a rotatable structure (10) provided with an extensible arm or foldable pivoting arm (12) arranged for connecting an imaging beam source (121) and an extensible structure or foldable pivoting structure (14) arranged for carrying an imaging beam receiver (141). The rotatable structure (10) is arranged for taking CBCT shots of the patient while the patient is located in an offset position with respect to an isocentre of the hadron therapy device, said offset position being in the direction of a rotational axis of the rotatable gantry (20). The rotatable structure (10) is arranged for being rotated while the rotatable gantry (20) remains fixed, and while the extensible or pivoting arm (12) and the extensible or pivoting structure (14) are in extended or unfolded position.

  • Patent number: 8111806
    Abstract: Therapy system (100) for irradiating a target volume (2) of a patient (1) with a charged particle beam (6), including a beam generator (3), a beam transport system (4), and a nozzle (5) for distributing the beam to the target volume (2), the nozzle (5) being, when in operation, under vacuum. The therapy system comprises an X-ray device (10) which is rotatably mounted inside the nozzle (5) between a first position and a second position. In the first position, an X-Ray source (12) within the X-Ray device is able to emit X-Rays along a charged particle beam path for generating an X-Ray image on a corresponding X-Ray receiving device (11) arranged opposite to the patient (1), said X-Ray image serving to determine a correct position of the target volume (2) with regard to the charged particle beam (6). In the second position, the X-Ray device (10) is set outside of a charged particle beam treatment path envelope (23), so that the charged particle beam (6) can reach and irradiate the target volume (2).
