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 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： A mobile diagnostic imaging system includes a battery system and charging system. The battery system is located in the rotating portion of the imaging system, and includes one or more battery packs, comprising electrochemical cells. Each battery pack includes a control circuit that controls the state of charge of each electrochemical cell, and implements a control scheme that causes the electrochemical cells to have a similar charge state. The battery system communicates with a charging system on the non-rotating portion to terminate charge when one or more of the electrochemical cells reach a full state of charge. The imaging system also includes a docking system that electrically connects the charging system to the battery system during charging and temporarily electrically disconnects the rotating and non-rotating portions during imaging, and a drive mechanism for rotating the rotating portion relative to the non-rotating portion.

摘要： A mobile medical imaging device that allows for multiple support structures, such as a tabletop or a seat, to be attached, and in which the imaging gantry is indexed to the patient by translating up and down the patient axis. In one embodiment, the imaging gantry can translate, rotate and/or tilt with respect to a support base, enabling imaging in multiple orientations, and can also rotate in-line with the support base to facilitate easy transport and/or storage of the device. The imaging device can be used in, for example, x-ray computed tomography (CT) and/or magnetic resonance imaging (MRI) applications.

摘要： A drive mechanism for a mobile imaging system comprises a main drive geared into a drive wheel for propelling the imaging system, including a base and one or more imaging components, across a surface. The drive mechanism can also include a scan drive that moves the drive mechanism and the one or more imaging components along an axis relative to the base to provide an imaging scan, and a suspension drive that extends the drive wheel relative to a bottom surface when the imaging system is in a transport mode and retracts the drive wheel relative to the bottom surface of the base when the imaging system is in an imaging mode. The drive wheel supports the weight of the imaging components, but does not directly support the base assembly, which can include pedestal and tabletop support. One or more casters located on the base can support the weight of the base assembly.

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.
