摘要： Some configurations of the present invention thus provide a method for producing images of an object. The method includes dynamically helically scanning an object on a moving table utilizing a scanning imaging system. During the scan, projection views of the object are acquired and stored together with corresponding table locations. A plane for reconstruction of an image of the object is selected. The stored table locations are used to determine geometric variables applicable to the stored projection views; and the stored projection views are filtered and backprojected utilizing the geometrical variables to reconstruct an image of the object at the reconstruction plane.

摘要： Methods and systems for scanning a patient by using a medical imaging device are provided. The methods include determining a defective cell in a row n of a detector of the medical imaging device, determining a mode of operation of the medical imaging device, estimating the output of the defective cell using the determined mode of operation and at least one of a conjugate sample of the defective cell, an adjusted conjugate sample of the defective cell, and an estimate of the output of the defective cell using an output of a corresponding cell in an adjacent row and reconstructing an image of the patient using the estimated value of the defective cell.

摘要： A method and system for an improved data acquisition system with an image detector array and an image processing system which finds a malfunctioning cell, interpolates a signal for the malfunctioning cell using neighboring channels of the cell, and corrects the interpolation with an error rate found in performing interpolations on neighboring rows with cells which are not malfunctioning. The image processing system may include a DAS and a reconstruction system. The step of finding a malfunctioning cell may be accomplished through a variety of methods, such as measuring discrepancies between a cell's and its neighboring cell's average readings over time and exposing the cells to x-rays which should produce similar readings in all the cells and comparing the cells' signals, looking for discrepancies. The step of interpolating and the step of correcting may take into consideration cells within the same projection view as the malfunctioning cell.

摘要： A system software solution for testing various network elements/entities and processes in a telecommunications network is provided. A network under test contains network entities which save data to a common database that is associated with processing particular test cases. A server correlates database data from the network under test and compares it to anticipated test case results. A disposition of the test cases is determined. Various elements of the invention interface appropriately, and process accordingly, to accomplish the testing and test result(s) disposition. In addition, the test system provides a means to verify billing records within the telecommunications network.

摘要： A system software solution for testing various network elements/entities and processes in a telecommunications network is provided. A network under test contains network entities which save data to a common database that is associated with processing particular test cases. A server correlates database data from the network under test and compares it to anticipated test case results. A disposition of the test cases is determined. Various elements of the invention interface appropriately, and process accordingly, to accomplish the testing and test result(s) disposition. In addition, the test system provides a means to verify billing records within the telecommunications network. Integrated into the system is logic that captures timepoints associated with critical events in a phone call from a test application perspective (particularly the events important to correct billing) and comparing those timepoints with actual results from the tested network. Timepoints are time information with milestones in the progress of call processing. Time information of applicable network elements is first assured to be synchronized, or translated for consistency. The test application timepoints are gathered, compared to billing records associated with the test case (e.g. call), and used to produce an accurate test case result.
