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.

摘要： A robotically controlled five degree-of-freedom x-ray gantry positioning apparatus, which is connected to a mobile cart, ceiling, floor, wall, or patient table, is being disclosed. The positioning system can be attached to a cantilevered o-shaped or c-shaped gantry. The positioning system can precisely translate the attached gantry in the three orthogonal axes X-Y-Z and orient the gantry about the X-axis and Y-axis while keeping the center of the gantry fixed, (see FIG. 1). 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. Additionally, a field of view larger than that provided by the detector is provided in pure AP (anterior/posterior) and lateral detector positions through additional combinations of multi-axis coordinated motion. Each axis can be manually controlled or motorized with position feedback to allow storage of gantry transformations. Motorized axes enable the gantry to quickly and accurately return to preset gantry positions and orientations. A system and method for enlarging the field of view of the object being imaged combines a rotation of the x-ray source and detector with a multi-axis translation of the gantry.
摘要翻译：公开了一种机器人控制的五自由度X射线门架定位装置，其连接到移动车，天花板，地板，墙壁或患者台。定位系统可以连接到悬臂的o形或c形台架上。定位系统可以精确地平移三个正交轴XYZ中的连接机架，同时保持台架的中心固定在X轴和Y轴上，（参见图1 ）。定位装置分别在X轴和Y轴上分别提供了台架的异中心和非等中心的“倾斜”和“摇摆”旋转。等轴“瓦格”旋转是两个平移和一个旋转的多轴组合。另外，通过多轴协调运动的附加组合，在纯AP（前/后）和横向检测器位置提供比检测器提供的视场大的视场。可以通过位置反馈手动控制或机动每个轴，以允许龙门架转换的存储。电动轴使龙门架快速准确地返回到预设的龙门架位置和方向。用于扩大正在成像的物体的视场的系统和方法将X射线源和检测器的旋转与台架的多轴平移相结合。
