20110101978 | MOTION INFORMATION CAPTURE AND AUTOMATIC MOTION CORRECTION FOR IMAGING SYSTEMS - Systems, methods and articles of manufacture are disclosed for compensating for motion of a subject during an MRI scan of the subject. k-space data may be received from the MRI scan of the subject. Motion information may be received for the subject. Based on the received motion information, a translational motion of the subject may be determined between a first point in time and a second point in time. A search space for motion correction may be reduced using the determined change and an error margin of the capturing technique. A motion-compensated, graphical image of the subject may be generated using the reduced search space. | 05-05-2011 |
20110105882 | CORRECTING SUBJECT MOTION IN MULTIPLE RESOLUTIONS IN MAGNETIC RESONANCE IMAGING - Systems, methods and articles of manufacture are disclosed for compensating for motion of a subject during an MRI scan of the subject. k-space data may be received from the MRI scan of the subject. A first graphical image may be generated from a first set of data elements from the k-space data. Similarly, a second graphical image may be generated from a second set of data elements from the k-space data. An offset in pixels may be determined by which to translate the second graphical image from the first graphical image to compensate for the motion. The k-space data may be modified at a sub-pixel offset relative to the determined offset. A motion-compensated graphical image of the subject may be generated from the modified k-space data. Doing so reduces the search space evaluated to sharpen images generated from the k-space data. | 05-05-2011 |
20110105883 | REAL TIME MOTION INFORMATION CAPTURE IN AN MRI ENVIRONMENT - Systems, methods and articles of manufacture are disclosed for capturing motion information in a magnetic resonance imaging (MRI) environment. A light sink in the MRI environment may detect light emitted from a plurality of light sources. Each of the plurality of light sources may emit light of a different frequency. Further, each of the plurality of light sources may be located at a different spatial position in the MRI environment. The detected light may be analyzed. A change in spatial position of the light sink may be computed based on the analysis. | 05-05-2011 |
20110107060 | TRANSPOSING ARRAY DATA ON SIMD MULTI-CORE PROCESSOR ARCHITECTURES - Systems, methods and articles of manufacture are disclosed for transposing array data on a SIMD multi-core processor architecture. A matrix in a SIMD format may be received. The matrix may comprise a SIMD conversion of a matrix M in a conventional data format. A mapping may be defined from each element of the matrix to an element of a SIMD conversion of a transpose of matrix M. A SIMD-transposed matrix T may be generated based on matrix M and the defined mapping. A row-wise algorithm may be applied to T, without modification, to operate on columns of matrix M. | 05-05-2011 |

20100205580 | GENERATING PARALLEL SIMD CODE FOR AN ARBITRARY TARGET ARCHITECTURE - Techniques are disclosed for automating the generation of parallel SIMD native source code in three major functional areas of data transmission, synchronization, and SIMD operations. An annotation standard is defined that is independent from native compilers and, coupled with a source-to-source compiler that provides high-level abstractions of data transmission, synchronization, and SIMD operations, relieves the need for programmers to work in a hardware-specific manner, while addressing issues of productivity and portability in a parallel SIMD computing environment. | 08-12-2010 |
20100205585 | FAST VECTOR MASKING ALGORITHM FOR CONDITIONAL DATA SELECTION IN SIMD ARCHITECTURES - Techniques are disclosed for generating fast vector masking SIMD code corresponding to source code having a conditional statement, where the SIMD code replaces the conditional statements with vector SIMD operations. One technique includes performing conditional masking using vector operations, bit masking operations, and bitwise logical operations. The need for conditional statements in SIMD code is thereby removed, allowing SIMD hardware to avoid having to use branch prediction. This reduces the number of pipeline stalls and results in increased utilization of the SIMD computational units. | 08-12-2010 |
20100241824 | PROCESSING ARRAY DATA ON SIMD MULTI-CORE PROCESSOR ARCHITECTURES - Techniques are disclosed for converting data into a format tailored for efficient multidimensional fast Fourier transforms (FFTS) on single instruction, multiple data (SIMD) multi-core processor architectures. The technique includes converting data from a multidimensional array stored in a conventional row-major order into SIMD format. Converted data in SIMD format consists of a sequence of blocks, where each block interleaves s rows such that SIMD vector processors may operate on s rows simultaneously. As a result, the converted data in SIMD format enables smaller-sized 1D FFTs to be optimized in SIMD multi-core processor architectures. | 09-23-2010 |

20130188271 | TAPE WIDTH MEASUREMENTS - A tape drive is disclosed. The tape drive determines a current tape width and writes data to the tape as well as the current tape width. The tape width written to the tape is associated with the data. When reading data from a tape the tape drive reads the stored tape width and adjusts the current tape width to match the stored tape width before reading the data associated with the stored tape width. | 07-25-2013 |
