Radiation systems with minimal or no shielding requirement on building
A radiation system includes: a first support; a first structure rotatably coupled to the first support so that the first structure is rotatable about a first axis relative to the first support; a second structure rotatably coupled to the first structure so that the second structure is rotatable about a second axis that forms a non-zero angle relative to the first structure; and a first radiation source connected to the second structure; wherein the first structure and the second structure are parts of a capsule for accommodating at least a portion of a patient.

Radiation Shielding Devices, Systems, and Methods
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.

NEUTRON CAPTURE THERAPY SYSTEM
A neutron capture therapy system is provided, including a neutron generating device and a beam shaping assembly. The neutron capture therapy system further includes a concrete wall forming a space for accommodating the neutron generating device and the beam shaping assembly and shielding radiations generated by the neutron generating device and the beam shaping assembly. A support module is disposed in the concrete wall, the support module is capable of supporting the beam shaping assembly and is used to adjust the position of the beam shaping assembly, and the support module includes concrete and a reinforcing portion at least partially disposed in the concrete. The neutron capture therapy system designs a locally adjustable support for the beam shaping assembly, so that the beam shaping assembly can meet the precision requirement, improve the beam quality, and meet an assembly tolerance of the target.
APPARATUS FOR SHIELDING RADIATION
An apparatus for shielding radiation emitted during a medical procedure. The apparatus includes a board positionable on top of a procedure table. The board extends laterally between a first board edge and a second board edge, and longitudinally between a third board edge and a fourth board edge. The board includes a plurality of apertures distributed along at least one of the board edges. At least one radiation shield is removably mountable to the board. The at least one radiation shield includes at least one peg engageable with any one of the apertures in the board. The apparatus can include a body shield assembly and/or an adjustable screen assembly.

Medical radiation shielding system for use with a radiation source below a table
A radiation shield assembly is described, configured to block radiation emanating from a radiation source from reaching a user. Two shields are supported by a support arm, and are configured to rotate and translate relative to one another about the support arm's longitudinal axis. This allows the shield to be easily configured and reconfigured as necessary to visualize various parts of a patients body via radiography.
