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： 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。定位系统能够精确地平移三个正交轴X-Y-Z中的连接机架，同时保持台架的中心固定，使台架绕X轴和Y轴定向（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。

摘要： A method and apparatus for producing a three-dimensional part from a plurality of planar layers using an ultrasonic welder. A sheet of planar material is placed on the partial part and ultrasonically welded, with the first sheet placed on a base. The sheet is cut to the shape of the partial part. The process of placing of the sheet materials on the partial, welding, and cutting of the two-dimensional contour layer is continued until part is complete. In a preferred embodiment, the three-dimensional part has layers of different material. The materials can be layers of incompatible materials for ultrasonic welding in which voids are created through interposed non-compatible materials for ultrasonic welding, to allow ultrasonic welding of compatible material layers spaced by a sheet of incompatible material. In a preferred embodiment a component, such as a thermal actuator; a optical component; an internal sensor; a plurality of electronic elements, or a mechanical actuator for creating a actively deformable part, is introduced between layers of material of the part. The method described allows the introduction of components which are sensitive to manufacturing temperatures. A pressure mask applies pressure to the top layer as the layer is ultrasonic welded to the part. In a preferred embodiment, the elongated sheets of material are carried on a supply drum and moved over the partial part using a feed system having the supply drum and a take-up drum.

摘要： A system and a method for acquiring image data of a subject with an imaging system is provided. The system can include a gantry that completely annularly encompasses at least a portion of the subject, which can be positioned along at an isocenter of the imaging system. The system can include a source and a detector positioned within and movable relative to the gantry on a rotor. The system can include a move control module that sets move data for each of the source, detector and rotor that causes the source, detector and rotor to move in a desired motion profile to acquire image data of a portion of the subject off the isocenter of the imaging system.
