Radiation protection clothing arrangement and method of wearing the radiation protection clothing arrangement. The radiation protection clothing arrangement includes a flexible coat having radiation protection material configurable to surround, in a state of use, an interior space and a bottom edge, a weight-relieving device that is embodied as a support skeleton connected to the flexible coat and that absorbs a weight of the flexible coat in multiple locations distributed in a direction of gravity and a support device, to which the support skeleton is connected, being arranged within a space extending in the direction of gravity from the interior space and being supportable, in the state of use, on an underlying surface.

Disclosed herein is a system, comprising: a first X-ray source comprising a plurality of X-ray generators configured to respectively emit a plurality of X-rays toward an object; and a first X-ray detector configured to detect images of the object formed respectively by the plurality of X-rays from the first X-ray source.

A travel handle (20) is provided with a pair of support plates (22) and a gripping bar (21) extended between the support plates (22). The pair of support plates (22) has a groove-like shape and is engaged with a slider (25) provided to a main body so that the support plates are reciprocally guided in a longitudinal direction inclined relative to the horizontal direction, and the reciprocal motion ends of the support plate in the reciprocating direction are regulated. The slider (25) is provided with a braking roller in contact with a groove portion side surface of the support plate (22) of the travel handle (20) and a braking control mechanism (26) for performing control such that the braking force by the travel handle (20) against the upward/downward movement of the travel handle (20) in the inclined direction is increased when the travel handle (20) is moved downward and decreased when the travel handle (20) is moved upward.

An X-ray tube device includes a main body that incorporates a bulb, which generates X-rays, a collimator that is provided to protrude from the main body in an irradiation direction of the X-rays in a part of a front surface (first surface), which is a surface of the main body, and has an irradiation window for irradiating the X-rays with an adjusted irradiation range, and connectors that are provided for connecting a guard unit for keeping a distance from a test object, between the front surface (first surface) of the main body and a front surface (second surface), which is a surface of the collimator where the irradiation window is provided.

An apparatus and related method for supporting X-ray imaging. The apparatus comprises an input interface (IN) for receiving an X-radiation scatter measurement obtained by an X-ray sensor (SX.sub.i) during operation of an X-ray imager (XI) for imaging a first object (PAT). A predictor component (PC) is configured to predict, based on said measurement, whether or not: i) a second object (P) is present, or ii) there is sufficient X-ray exposure of said first object (PAT). The apparatus comprises an output interface (OUT) for outputting a predictor signal indicative of an outcome of said prediction.

A system of shields designed to provide substantially greater protection, head to toe, against radiation exposure to health care workers in a hospital room during procedures which require real-time imaging. The shields are placed around the patient and the x-ray table and provide protection even when the x-ray tube is moved to various angles around the patient.

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.

A method for collision detection of a radiotherapy equipment includes determining a collision-prone position of a target to be detected; and determining whether the target to be detected having a risk of collision with the radiotherapy equipment according to collision risk analysis data that is capable for reflecting a magnitude relationship between a first distance and a second distance. The first distance is a distance from the collision-prone position to a reference position of the radiotherapy equipment, and the second distance is a minimum distance between a target component of the radiotherapy equipment and the reference position. A distance between the reference position and the target component of the radiotherapy equipment is relatively constant when the target component of the radiotherapy equipment rotates around a rotation axis.
