A cabin type beam irradiation apparatus and a method for performing beam irradiation method are provided. According to an embodiment, the beam irradiation apparatus comprises: a gantry having a hollow frame structure, the hollow portion of which being formed as a treatment cabin; a first guide rail, which is fixedly arranged on the frame; a treatment head, which is slidably arranged on the first guide rail; and an entry door, which may be openably and closably arranged on the gantry. The beam irradiation apparatus can perform radiotherapy on patients in a standing or sitting posture. Imaging guidance is additionally used to ensure the accuracy of the treatment position, and thus highly focused radiation is achieved by (non)coplanar radiotherapy. Further, the apparatus may have self-shielding function, and can reduce the difficulty and cost for construction of a machine room.

The disclosure relates to a system for immobilizing and supporting a subject in a medical procedure. The system may include a treatment apparatus configured to generate a radiation beam, and a device for immobilizing a subject. The device may include an immobilizing component for immobilizing at least one portion of the subject, and a radio frequency (RF) coil configured to receive a magnetic resonance (MR) signal related to the at least one portion of the subject. The immobilizing component may be configured to switch between a first mode and a second mode. The first mode may correspond to a positive pressure or a constant pressure related to the device. The second mode may correspond to a space of vacuum or substantially of vacuum related to the device. The RF coil may be located in the immobilizing component according to a position where the radiation beam is incident on the device.

The invention comprises a method and apparatus for treating a tumor of a patient, in a beam treatment center comprising a floor, with positively charged particles, comprising: (1) a synchrotron mounted to an elevated floor section above the floor of the beam treatment center; (2) a beam transport system, comprising: at least three fixed-position beam transport lines, where none of the synchrotron and the beam transport system penetrate through the floor of the beam treatment center; (3) the positively charged particles transported from the synchrotron, through the beam transport system, to a position above a patient positioning system during use; and (4) an optional repositionable nozzle system connected to a first, second, and third fixed-position beam transport line at a first, second, and third time, respectively, where the nozzle track forms an arc of a circle and the repositionable nozzle system moves along the nozzle track.

Systems for immobilizing a patient are disclosed. The system includes at least one preform formed from a low melting temperature thermoplastic, the preform being configured to be formed to the anatomy of the patient, at least one frame coupled to the at least one preform, and at least one support configured to support the anatomy of the patient. The system also includes at least one lock mechanism coupled to at least one of the frame and the support and configured to couple the at least one frame to the at least one support, and at least one adjuster mechanism coupled to at least one of the at least one frame and the at least one support and configured to selectively adjust a distance between the at least one frame and the at least one support while the at least one frame is coupled to the at least one support.

A headrest for an immobilization system for immobilizing at least a part of a patient is provided. The headrest includes a supporting structure and a sheet-like formed elastic panel attached to the supporting structure on at least two opposite sides of the elastic panel. The elastic panel is configured to support at least a part of a head and/or at least a part of a neck of a patient, wherein at least a part of the elastic panel is stretchable and configured to stretch when said at least part of the head and/or neck of the patient is arranged on the elastic panel, such that a shape of said at least part of the elastic panel is formed corresponding to a shape of said at least part of the head and/or neck of the patient.

A joint assembly releasably connecting an extension panel to a patient support panel mounted on a pedestal includes a first body member configured to be coupled to the extension panel and a second body member configured to be coupled to the patient support panel. The first body member has a cavity member extending in an engagement direction and an attachment member. The second body member includes a tab member and a latch. The first body member is engageable with the second body member by moving the cavity member with respect to the tab member and by latching the attachment member with the latch. The cavity member is moveable translatable over the tab member in the engagement direction up to a locking position where the latch latches on the attachment member.

An assembly for a thermoplastic preform for securing body part is provided. The thermoplastic preform is deformable when heated to a softening temperature by an external heating source and hardens when cooled below the softening temperature. The assembly includes the thermoplastic preform and a protective cover surrounding the thermoplastic preform. The thermoplastic preform is sealed within the protective cover. The protective cover is heat resistant up to a temperature that exceeds the softening temperature for the thermoplastic preform. The protective cover transfers heat from the external heating source to the thermoplastic preform and prevents airborne and waterborne bacteria from contacting the thermoplastic preform.

The treatment couch includes a couch panel, a main supporting structure, an auxiliary supporting structure and a supporting beam. Both ends of the supporting beam are respectively connected to the main supporting structure and the auxiliary supporting structure.
