摘要： Systems and methods for obtaining two-dimensional images of an object, such as a patient, in multiple projection planes. In one aspect, the invention advantageously permits quasi-simultaneous image acquisition from multiple projection planes using a single radiation source.An 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 which is adapted to project radiation onto said object from a plurality of 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 rotatable 360 degrees around the interior of the ring. The source 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： An x-ray scanning imaging apparatus with a generally O-shaped gantry ring, which has a segment 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 the 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 and related method comprising a source that projects a beam of radiation in a first trajectory; a detector located a distance from the source and positioned to receive the beam of radiation in the first trajectory; an imaging area between the source and the detector, the radiation beam from the source passing through a portion of the imaging area before it is received at the detector; a detector positioner that translates the detector to a second position in a first direction that is substantially normal to the first trajectory; and a beam positioner that alters the trajectory of the radiation beam to direct the beam onto the detector located at the second position. The radiation source can be an x-ray cone-beam source, and the detector can be a two-dimensional flat-panel detector array. The invention can be used to image objects larger than the field-of-view of the detector by translating the detector array to multiple positions, and obtaining images at each position, resulting in an effectively large field-of-view using only a single detector array having a relatively small size. A beam positioner permits the trajectory of the beam to follow the path of the translating detector, which permits safer and more efficient dose utilization, as generally only the region of the target object that is within the field-of-view of the detector at any given time will be exposed to potentially harmful radiation.

摘要： An apparatus and method for reconstructing image data for a region are described. A radiation source and multiple one-dimensional linear or two-dimensional planar area detector arrays located on opposed sides of a region angled generally along a circle centered at the radiation source are used to generate scan data for the region from a plurality of diverging radiation beams, i.e., a fan beam or cone beam. Individual pixels on the discreet detector arrays from the scan data for the region are reprojected onto a new single virtual detector array along a continuous equiangular arc or cylinder or equilinear line or plane prior to filtering and backprojecting to reconstruct the image data.

摘要： An x-ray scanning imaging apparatus with a rotatably fixed generally O-shaped gantry ring, which is connected on one end of the ring to support structure, such as a mobile cart, ceiling, floor, wall, or patient table, in a cantilevered fashion. The circular gantry housing remains rotatably fixed and carries an x-ray image-scanning device that can be rotated inside the gantry around the object being imaged either continuously or in a step-wise fashion. The ring can be connected rigidly to the support, or can be connected to the support via a ring positioning unit that is able to translate or tilt the gantry relative to the support on one or more axes. Multiple other embodiments exist in which the gantry housing is connected on one end only to the floor, wall, or ceiling. The x-ray device is particularly useful for two-dimensional multi-planar x-ray imaging and/or three-dimensional computed tomography (CT) imaging applications.
