Abstract
An x-ray imaging system is presenting having two independently articulated arms supporting an x-ray tube and x-ray detector, respectively. The detector is included in a detector assembly that further includes a display and user interface for controlling the arms. The detector assembly further includes at least one lead shield that is extendable to protect an operator stationed at the display during use.
Claims20
An x-ray imaging system comprising:
- an x-ray source producing an x-ray beam directed along a source axis;
- an x-ray detector assembly including a frame supporting a detector for detecting x-rays received along a detector axis aligned with the source axis, and a user interface mounted to the frame;
- a first and second articulated arm each having at least two independent axes of motion, the first articulated arm holding the x-ray source at its first end, the second articulated arm holding the x-ray detector at its first end;
- at least one extendable x-ray blocking shield connected to the frame that is movable in a longitudinal direction between a retracted and extended configuration via an opening extending through a first end of the frame.
1 more element
An integrated x-ray imaging detector assembly for use in an x-ray imaging system, the detector assembly comprising:
- a support frame;
- an x-ray detector module supported by the frame and operable to receive a beam of x-rays emitted from an x-ray source and passed through a target along a detector axis, and further operable to produce electrical signals in response to the received beam of x-rays;
- a display terminal supported by the frame and disposed behind the detector module with respect to the direction of x-ray beam travel, the display terminal being configured to receive the electrical signals and produce an output image corresponding to the electrical signals;
- and
- at least one extendable x-ray blocking shield connected to the frame that is movable in a longitudinal direction between a retracted and extended configuration via an opening extending through the frame.
