Abstract: An intra-oral device for positioning oral tissues during medical treatment, for example, radiation treatment. The device includes upper and lower dental arch members configured to engage the maxillary and mandibular teeth or edentulous arch(es) of a patient, respectively. Moldable material is maintained within channels formed in the dental arch members by partially extruding the material through keyways formed in the arch members during the bite mold process. The upper and lower dental arch members are operatively coupled to provide a dental arch assembly. A protective element to displace or depress a patients tongue is secured at a suitable working position with respect to the dental arch assembly via a threaded strut adjustably coupled between the protective element and a support structure disposed between the dental arch members.

Abstract: A self-shielded and computer controlled system for performing non-invasive stereotactic radiosurgery and precision radiotherapy using a linear accelerator mounted within a two degree-of-freedom radiation shield coupled to a three-degree of freedom patient table is provided. The radiation shield can include an axial shield rotatable about an axial axis and an oblique shield independently rotatable about an oblique axis, thereby providing improved range of trajectories of the therapeutic and diagnostic radiation beams. Such shields can be balanced about their respective axes of rotation and about a common support structure to facilitate ease of movement. Such systems can further include an imaging system to accurately deliver radiation to the treatment target and automatically make corrections needed to maintain the anatomical target at the system isocenter. Various subsystems to automate controlled and coordinated movement of the movable shield components and operation of the treatment related subsystems to optimize performance and ensure safety are also provided.

Abstract: A neutron-capture therapy system includes a charged particle beam generation unit, a beam transmission unit and a neutron beam generation unit. The charged particle beam generation unit includes an ion source and an accelerator. The accelerator accelerates charged particles generated by the ion source, so as to obtain a charged particle beam of the required energy. The neutron beam generation unit includes a target, a beam shaping body and a collimator. The charged particle beam irradiates onto the target through the beam transmission unit to generate neutrons, which sequentially pass through the beam shaping body and the collimator to form a neutron beam for therapy. The neutron-capture therapy system is accommodated in a concrete building including an irradiation room, an accelerator chamber and a beam transmission chamber. The neutron beam generation unit is at least partially accommodated in a partition wall of the irradiation chamber and the beam transmission chamber.

Abstract: An ophthalmic radiation device having a substantially light-transparent wand configured to emit light propagating through the wand light from a series of illumination ports at least partially circumscribing a radioactive source disposed in the holder, thereby providing a visual reference for identifying a position of the radioactive source. Embodiments are directed at effectively directing light from a light source through the body of the wand to illumination ports by using the wand body itself as the light guide. The illumination ports are used as reference points by a medical practitioner to facilitate placing the device into a correct treatment position.

Abstract: A radiation therapy system comprises a magnetic resonance imaging (MRI) system combined with an irradiation system, which can include one or more linear accelerators (linacs) that can emit respective radiation beams suitable for radiation therapy. The MRI system includes a split magnet system, comprising first and second main magnets separated by gap. A gantry is positioned in the gap between the main MRI magnets and supports the linac(s) of the irradiation system. The gantry is rotatable independently of the MM system and can angularly reposition the linac(s). Shielding can also be provided in the form of magnetic and/or RF shielding. Magnetic shielding can be provided for shielding the linac(s) from the magnetic field generated by the MM magnets. RF shielding can be provided for shielding the MRI system from RF radiation from the linac.
