Abstract: The present disclosure relates to a medical apparatus including a magnetic resonance imaging (MRI) system for acquiring magnetic resonance (MR) data from an imaging volume. In one implementation, the MRI system may include a particle beam apparatus having a particle beam line for producing, directing and managing a particle beam of charged particles, a magnetic correction device for applying a magnetic correction to a magnetic field perturbation within the imaging volume, and a controller for controlling the magnetic correction device. The controller may be configured to provide a spatially optimized magnetic correction within a restricted volume of the imaging volume during a spatially optimized magnetic correction period posterior to an excitation period during which a selected slice from the imaging volume is excited.

Abstract: The present disclosure relates to a particle therapy apparatus for irradiating a target with a charged particle beam and having a particle accelerator and an isocentric gantry rotatable about an axis. The gantry includes a sequence of bending magnets to successively bend and direct the particle beam towards the isocentre of the gantry. A last bending magnet of the sequence is configured to bend the particle beam in a first plane including the isocentre and making a large angle with the axis. The gantry further includes a first scanning magnet arranged upstream of the last bending magnet and configured to scan the particle beam over the target. The apparatus also includes a magnetic resonance imaging (MRI) system having two main magnet units arranged on both sides of the isocentre and configured to generate a main magnetic field parallel to or coaxial with the axis.

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.
