摘要： A device for supporting and positioning a patient in a medical equipment comprises a patient support means, a robotic arm supporting the patient support means, and an robotic wrist with at least two motorized rotational degrees of freedom, the robotic wrist being borne by the robotic arm and bearing the patient support means. A translational release unit is connected between the robotic wrist and the patient support means. It includes an XY translation mechanism providing two translational degrees of freedom and a translation locking mechanism cooperating with the XY translation mechanism. The translation locking mechanism is switchable between a locked state, in which it locks the two translational degrees of freedom of the XY translation mechanism in a mechanically defined position, and an unlocked state, in which the two translational degrees of freedom are unlocked.

摘要： The invention is related to a method and apparatus for verifying the beam range in a target irradiated with a charged hadron beam, such as a proton beam. The beam range is the location of the Bragg peak in the target, being the location where the largest portion of the dose is delivered. The method utilizes a prompt gamma camera provided with a slit-shaped opening, so as to be able to produced a 1-dimensional profile of the dose distribution along the beam line. The camera is mounted with the slit oriented perpendicularly to the beam line. The method comprises the steps of calculating a position of the camera with respect to a target, for a plurality of beam energies and spots to be irradiated. The method further comprises the steps of verifying the beam range for said plurality of spots, and delivering a value representative of the difference between the estimated beam range and the actual beam range. The apparatus of the invention is provided with a positioning module for positioning the camera.

摘要： 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.

摘要： An energy degrader (1) for attenuating the energy of a charged particle beam (2), comprising a first energy attenuation member (10) presenting a annular beam entry face (11) and a continuous helical beam exit face (12), a second energy attenuation member (20) presenting a continuous helical beam entry face (21) and an annular beam exit face (22), the first and second helical surfaces facing each other, and a drive assembly configured for rotating the first and/or the second energy attenuation members around respectively a first axis (A1) and a second axis (A2) which are parallel to each other. Such a degrader can have a small moment of inertia, allowing more accurate and faster variation of the beam energy.
