20080279337 | FILTER UNIT, X-RAY TUBE UNIT, AND X-RAY IMAGING SYSTEM - A small-sized filter unit of a simple structure, as well as an X-ray tube unit and an X-ray imaging system both having the filter unit, are implemented, A filter unit in a first aspect of the present invention comprises a filter plate, the filter plate having a first filter, a second filter disposed in a first direction with respect to the first filter and a third filter disposed in a second direction having a predetermined angle from the first direction with respect to the first filter, a guide plate having a guide frame for movement of the filter plate in the first and second directions, and a drive device for moving the filter plate. | 11-13-2008 |
20100054420 | ADJUSTING DEVICE FOR BARRIER BLADE OF SCATTERED X-RAY - An adjusting device for a barrier blade includes a barrier blade for limiting scattered X-ray of a tube and a base plate for mounting the barrier blade. The adjusting device also includes a barrier blade support and a drive unit, wherein said barrier blade support includes a sliding post; said barrier blade support is fixedly connected to the barrier blade and mounts the barrier blade in the opening of the base plate; and the drive unit controls and changes the path of the sliding post to cause the sliding post to drive the barrier blade support to make rectilinear movement on the base plate, thereby driving the barrier blade thereon to make rectilinear movement in the opening of the base plate. This adjusting device for a barrier blade of scattered X-ray has advantages of simple structure, small space, high reliability, and low cost. | 03-04-2010 |
20100185478 | Collaborative Working of Business Process Management Methods - The collaborative working of process-oriented and event-based business process management (BPM) methods in a service-oriented architecture (SOA) is supported. The execution models of the business process include process-oriented execution models and event-based execution models. The process-oriented execution models and the event-based execution models are executed at runtime. A bridge implements the interaction between the process-oriented runtime execution and the event-based runtime execution. | 07-22-2010 |
20100189216 | FILTER AND X-RAY IMAGING SYSTEM - A filter capable of adjusting spectrum in multiple stages and that capable of attaining the reduction of size, as well as an X-ray imaging system having such a filter, are provided. The filter, which is for adjusting the spectrum of passing radiation, comprises a support plate having an aperture for passage therethrough of radiation, plural filter plates supported by the filter plate and having mutually different filter characteristics, and moving device for moving the plural filter plates selectively to a position to close the aperture and a position to open the aperture. | 07-29-2010 |
20100246775 | FILTER AND X-RAY IMAGING APPARATUS USING THE FILTER - A filter includes a plurality of filter plates for adjusting X-ray energy spectrum, a plurality of rails for fixedly supporting the filter plates, a plurality of cams which are respectively provided with a groove curve on a surface thereof, a driving wheel for driving the cams, and a plurality of link levers, each link lever being connected to one of the filter plates at one end and being mounted to an axis at an opposite end such that the link lever is rotatable about the axis, and each link lever being provided with a pin which is in cooperation with the groove curve of the corresponding cam so that the link lever proceeds with a reciprocating movement according to rotation of the corresponding cam to move the filter connected to it into or out of the X-ray passing space. The plurality of cams are respectively located at different sides of the driving wheel to move the filter plates into the X-ray passing space from different directions. | 09-30-2010 |
20100260318 | BLADE DEVICE AND X-RAY IMAGING APPARATUS - A blade device for forming a hollow cone-like radiation includes a pair of blade members opposed to each other symmetrically at a fixed inclination angle in a first direction perpendicular to the axis of the cone, a pair of second blade members opposed to each other symmetrically at a variable inclination angle in a second direction perpendicular to the axis of the cone and also perpendicular to the first direction, a pair of lever members fixed respectively at one ends thereof to faces of the pair of second blade members on the side opposite to the mutually confronting side, and lever actuating unit for pivoting the pair of lever members about respective shafts. | 10-14-2010 |
20120134476 | COLLIMATOR FOR X-RAY IMAGING APPARATUS AND THE ASSEMBLE AND DISASSEMBLE METHOD THEREOF - A collimator for X-ray imaging apparatus is provided. The collimator includes a collimator housing including a tube flange, a tube, a locating ring configured to be mounted at an outlet of the tube flange, and at least one tongue set fixed on the locating ring. An outstretching direction of the tongue is towards a center of the locating ring. | 05-31-2012 |
20120148028 | LINKAGE MECHANISM, A COLLIMATOR, AND AN X-RAY MACHINE - A linkage mechanism of a scattered ray inhibition apparatus and a radiation field control apparatus is provided. The linkage mechanism includes a first timing belt, a second timing belt, and a transmission mechanism between the first timing belt and the second timing belt, wherein the scattered ray inhibition apparatus is mounted on the first timing belt, the radiation field control apparatus is mounted on the second timing belt, the transmission ratio of the transmission mechanism is equal to the ratio of the moving speed of the scattered ray inhibition apparatus to the moving speed of the radiation field control apparatus. | 06-14-2012 |
