Abstract: A computer system and a data recovery method are provided. The computer system includes an embedded controller (EC). The data recovery method includes following steps. When the computer system stores data into the EC through a basic input/output system (BIOS), the data is backed up into a non-volatile random access memory (NVRAM) by the BIOS. The EC enters a power-off mode. The data is obtained from the NVRAM and is stored back to the EC after the EC leaves the power-off mode. Accordingly, the EC recovers from the power-off mode.

Abstract: A method for removing “grid line artifacts” from x-ray images without changing the diagnostic quality of the x-ray image is presented. The method utilizes the Fourier spectrum of the image to detect the grid line frequencies and employs spectral domain filtering to remove the grid line spectral components. The diagnostic information is preserved by modifying the grid line spectral components to be indistinguishable from local variations in image intensity values, and edge density of the x-ray image.

Abstract: A source applies imaging energy that passes through an object being imaged and is then detected by a detector connected to a processor. A scanning trajectory includes first and second scan paths. The first scan path has a shadow zone where a complete image cannot be obtained from corresponding first scan path data. The second scan path provides data from the shadow zone. Partial images from the first scan path and the second scan path are Fourier transformed after which some data is removed prior to adding the Fourier data together. An inverse Fourier transform is then used to provide an overall image.

Abstract: A system is provided for reconstructing x-ray tomographic images based upon the circle-and-line orbit. The system includes the steps of combining, in the frequency domain, images reconstructed separately from the circular and linear orbit data. Specifically, the method involves the steps of (1) converting the shadow zone into a shadow cone in frequency domain, (2) mapping the shadow cone in 3D Fourier space onto a set of 2D Fourier planes, (3) removing data lying within the region marked as the projection of the shadow cone from the Fourier transform of the circular orbit data and patching the same from the Fourier transform of the line orbit data, (4) transforming each 2D Fourier plane into a respective 2D image plane, and (5) converting the horn-shaped volume back to a grid volume. An interpolation technique is also provided for reconstructing the line orbit data using a Direct Fourier method (DFM).
