摘要： A technique for acquiring desired image data in an imaging system comprising at least one radiation source and a detector is described. Initially, preliminary image data corresponding to an object may be acquired. Further, at least one parameter associated with the radiation source and corresponding to a particular view angle of the radiation source may be determined based on the preliminary image data and a priori information. Similarly, at least one parameter associated with the detector and corresponding to the particular view angle may be determined based on a priori information and the preliminary image data. Efficient operating modes of the radiation source and the detector corresponding to the particular view angle may be selected based on the determined parameters to achieve a desired system performance. Subsequently, the final image data may be acquired using the selected operating modes of the radiation source and the detector.

摘要： A diagnostic imaging system includes an x-ray source that emits a beam of x-ray energy toward an object to be imaged and an energy discriminating (ED) detector that receives the x-ray energy emitted by the x-ray energy source. The ED detector includes a first layer having a first thickness, wherein the first layer comprises a semiconductor configurable to operate in at least an integrating mode and a second layer having a second thickness greater than the first thickness, and configured to receive x-rays that pass through the first layer. The system further includes a data acquisition system (DAS) operably connected to the ED detector and a computer that is operably connected to the DAS. The computer is programmed to identify saturated data in the second layer and substitute the saturated data with non-saturated data from a corresponding pixel in the first layer.

摘要： A superconductive lead assembly for a superconductive device (e.g., magnet) cooled by a cryocooler coldhead having first and second stages. A first ceramic superconductive lead has a first end flexibly, dielectrically, and thermally connected to the first stage and a second end flexibly, dielectrically, and thermally connected to the second stage. A first glass-reinforced-epoxy lead overwrap is in general surrounding contact with and attached to the first superconductive lead. The first lead overwrap has a coefficient of thermal expansion generally equal to that of the first superconductive lead. The lead overwrap protects the lead from moisture damage and from breakage during handling. For added protection against shock and vibration while in the device, the lead assembly is surrounded by a (e.g., polystyrene foam) jacket surrounded by a helically-wound metallic wire surrounded by a glass-reinforced-epoxy jacket overwrap surrounded by a rigid support tube.

摘要： X-ray detector system with improved spatial resolution for a computed tomography systems is provided. The detector system may include pairs of first and second detector arrays, with each array containing detector elements of a different design. In one embodiment, the first array may comprise a first, relatively thin and continuous (i.e., monolithic) scintillation layer with an array of individual diodes positioned to receive light generated within the scintillation layer. The second array may comprise a second, relatively thick scintillation layer formed of separate scintillator elements. An array of diodes may be positioned to receive radiation from the scintillation layer such that each diode element is aligned to primarily receive radiation from one scintillator element in the layer. The structural arrangements of the detector system may also be adapted for applications involving direct conversion of x-ray energy.
