摘要： PROBLEM TO BE SOLVED: To provide an X-ray gantry positioning apparatus, which is connected to a mobile cart, ceiling, floor, wall, or patient table, and robotically controlled, and which can precisely translate the attached gantry in the three orthogonal axes X-Y-Z. SOLUTION: This positioning system can orient the gantry about the X-axis and Y-axis while keeping the center of the gantry fixed. The positioning apparatus provides both iso-centric and non iso-centric "Tilt" and "Wag" rotations of the gantry around the X-axis and Y-axis respectively. The iso-centric "Wag" rotation is a multi-axis combination of two translations and one rotation. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a system for obtaining two-dimensional images of an object in multiple projection planes that permits quasi-simultaneous image acquisition from multiple projection planes using a single radiation source. SOLUTION: The imaging apparatus comprises: a gantry having a central opening for positioning an object to be imaged; a source of radiation that is rotatable around the interior of the gantry ring and adapted to project radiation onto the object from multiple different projection angles; and a detector system adapted to detect the radiation at each projection angle to acquire object images from multiple projection planes in a quasi-simultaneous manner. The gantry can be a substantially "O-shaped" ring with the source of radiation rotatable 360 degrees around the interior of the ring. The source of radiation can be an x-ray source, and the imaging apparatus can be used for medical x-ray imaging. The detector array can be a two-dimensional detector, preferably a digital detector.

摘要： PROBLEM TO BE SOLVED: To provide an imaging apparatus having a substantially O-shaped gantry ring including an X-ray source and a detector, in which the gantry ring can be fixed and connected to a support body or can be connected to a support structure through a ring-positioning unit which can move a gantry in parallel or incline it relative to the support body on one or a plurality of axes. SOLUTION: The X-ray scanning imaging apparatus has the substantially O-shaped gantry ring 11 which is rotatably fixed. One end of the gantry ring is connected to the support structure such as a moving carriage 12, a ceiling, a floor surface, a wall surface or a patient-support table in a cantilever form. The annular gantry holds an X-ray image scanning device which is rotatably fixed and which can continuously or gradually rotate around an object to be imaged inside the gantry.

摘要： An x-ray scanning imaging apparatus (10) with a generally O-shaped gantry ring (11), which has a segment (16) that fully or partially detaches (or "breaks") from the ring to provide an opening through which the object to be imaged may enter interior of the ring in a radial direction. The segment can then be re-attached to enclose the object within gantry. Once closed, the circular gantry housing remains orbitally fixed and carries an x-ray image-scanning device that can be rotated inside the gantry 360 degrees around the patient either continuously or in a step-wise fashion. The x-ray device is particularly useful for two-dimensional and/or three-dimensional computed tomography (CT) imaging applications.

摘要： An imaging apparatus (10) comprising a gantry (11) having an interior diameter, a radiation source (13) and a detector (14) rotatable about the interior of the gantry to obtain images of an object positioned inside the gantry, a support structure (12), a gantry positioning apparatus (20) that secures the gantry to the support structure (12) in a cantilevered manner, the positioning apparatus operable to translate the gantry in two perpendicular directions, and a control system that actuates the gantry positioning apparatus to translate the gantry in coordination with the rotation of the source and detector, such that, for a rotational position of the source (13) and detector (14), the detector (14) is tangent to a virtual circle centered on and containing the object being imaged, where the interior diameter of the gantry (11) is greater than a diameter of the virtual circle.
