A housing system for a radiotherapy apparatus (100, 200). The system comprises a support structure configured to support a source of radiation, a cover (208), and a lock (214). The cover (208) is hingeably attached to the support structure and movable between a closed position, in which the cover (208) shields the source of radiation, an open position. The lock (214) is configured to releasably lock the cover (208) in the closed position.

Apparatuses (devices, systems) and methods for shielding (protecting) surroundings around periphery of regions of interest located inside objects (e.g., patients) from radiation emitted by X-ray systems towards the objects. Apparatus includes: at least one radiation shield assembly including a support base connectable to an X-ray system radiation source or detector, and a plurality of radiation shield segments sequentially positioned relative to the support base, thereby forming a contiguous radiopaque screen configured for spanning around the region of interest periphery with a radiopaque screen edge opposing the object. Radiation shield segments are individually, actively controllable to extend or contract to selected lengths with respective free ends in directions away from or towards the support base(s), for locally changing contour of the radiopaque screen edge. Applicable for shielding (protecting) medical personnel, and patients, from exposure to X-ray radiation during medical interventions or/and diagnostics.

An apparatus for use with a medical system, the medical system comprising a medical device configured to treat and/or image a patient, includes: a camera configured to capture an image of a first mirror, wherein the image of the first mirror contains an image of at least a part of the patient and/or an image of at least a part of the medical system; wherein the camera comprises electronics that are not radiation-hard.

A beam shaping assembly for neutron capture therapy includes a beam inlet, a target having nuclear reaction with an incident proton beam from the beam inlet to produce neutrons forming a neutron beam, a moderator adjoining to the target, a reflector surrounding the moderator, a thermal neutron absorber adjoining to the moderator, a radiation shield arranged inside the beam shaping assembly and a beam outlet. The material of the moderator is subjected to a powder sintering process using a powder sintering device so as to change powders or a power compact into blocks. The reflector leads the neutrons deviated from the main axis back. The thermal neutron absorber is used for absorbing thermal neutrons so as to avoid overdosing in superficial normal tissue during therapy. The radiation shield is used for shielding leaking neutrons and photons so as to reduce dose of the normal tissue not exposed to irradiation.

New techniques for remote administration of medicine and medical devices using an external guidance and activation system are provided. In some embodiments, medicine(s) and/or medical device(s) is/are energized to a predetermined threshold energy level by externally applied radiation, and then driven into the treatment target. The design of such device(s) (e.g., injectable machine(s)) may include sub-device(s), e.g., medical payload-carrying reservoir(s), injector(s) and abrasive tool(s), which may be activated magnetically and/or by such radiation. In some aspects, such sub-device(s) include actuable housing(s) and/or other sub-tool(s), delivering drugs to specific locations commanded by a control system or a user. In other aspects, a medicine and/or device is provided with multiple dipoles, each oriented differently in three-dimensional space, allowing a guidance control system, remote from the medicine or device, to drive the movement and three-dimensional orientation of the medical agent or particle according to a three-dimensional path.

A radiotherapy system (220, 320) comprises a first rotary support apparatus (204, 304) configured to support a radiation beam source (200, 300) and to cause a radiation beam source (200, 300) to rotate about a rotation axis (218, 318, 518), a second rotary support apparatus (214, 314, 414, 514) and a radiation shield (202, 302, 402, 502) mounted to the second rotary support apparatus (214, 314, 414, 514). The second rotary support apparatus (214, 314, 414, 514) is configured to cause the radiation shield (202, 302, 402, 502) to rotate about the rotation axis (218, 318, 518).

In general, radiation shielding systems that shield radiation from multiple directions are described. In one embodiment, a method of shielding radiation is provided, including supporting a shielding device on an object proximate a radiation source, positioning a first shielding portion in a vertical position relative to the object, positioning a second shielding portion to extend away from the first portion, the second shielding portion attached to the first portion, and shielding radiation from the radiation source by the first shielding portion and the second shielding portion such that the first and second shielding portions provide a radiation shielding zone for a healthcare practitioner.

The disclosure is directed to devices for use in radiation therapy. Various configurations of shielding materials within shielding layers, such as for use in shielding radiation from radioactive sources within implanted radioactive carriers, are discussed herein.

A neutron capture therapy system, including a vacuum tube for transmitting a charged particle beam, a neutron generating part for generating a neutron beam, and a beam shaping assembly for shaping the neutron beam. The beam shaping assembly is provided with an accommodating part. The neutron generating part is disposed at an end of the vacuum tube. The vacuum tube has a first position and a second position. The neutron capture therapy system further includes a removal device, which includes a moving part that drives the vacuum tube to move. The moving part has a third position and a fourth position. When the moving part is in the third position, the vacuum tube is in the first position. When the moving part is in the fourth position, the vacuum tube is in the second position, and the neutron generating part is located at the outer side of the beam shaping assembly.

This patent application claims the use of directed energy in the form of electronically scanned ion beams to form plastic parts by selectively curing commodity or engineering resin in the shape of the part. Polymerization is limited to the vicinity of the controlled Bragg-peak of the ion beam (i.e., where linear energy transfer is maximized), if necessary, by the use of chemical polymerization inhibitors or conditions that inhibit polymerization.
