摘要： Magnetic resonance (MR) calibration data are acquired using a plurality of radio frequency receive coils, and both coil sensitivity maps and reference projection vectors are generated based on the MR calibration data. During imaging, extra navigator projection vectors are acquired, or part of the imaging data can be used as navigator projection vectors. Partially parallel imaging (PPI) can performed to enhance the navigation information. The navigator projection vectors and the reference projection vectors are sensitivity weighted using the coil sensitivity maps to generate navigator sensitivity weighted projection vectors (navigator SWPV) and reference sensitivity weighted projection vectors (reference SWPV) respectively, and these are compared to generate subject position information. The subject motions are compensated prospectively or retrospectively using the generated subject position information. The motion compensation may be prospective, performed by adjusting an imaging volume of the PPI based on the subject position information.

摘要： A method of operating a communication system is disclosed. A first communication session between a first base station and a mobile station is established. A service session between a first access network and the mobile station is established. When the mobile station moves to the service area of a new base station, a second communication session between a second base station and the mobile station is established. A distance between the first base station and the second base station is determined. If the distance exceeds a criteria, the service session is handed off a second access network. The criteria, which must be greater than zero, corresponds to the number of base station service areas separating the first base station and the second base station.

摘要： Embodiments of the invention pertain to a method and apparatus for image reconstruction for parallel Magnetic Resonance Imaging (MRI). In a specific embodiment, a method for image reconstruction in image space is provided. The method can suppress aliasing caused by undersampling when the number of sampling lines in k-space is reduced to increase the imaging speed. In an embodiment, suppressing aliasing from under-sampling can improve the quality of images reconstructed from the data acquired using a MRI coil array. In an embodiment, the method operates in image space and achieves a good resolution. In the reconstruction, the sum of square errors can be minimized within a region of interest, which can allow the image reconstruction to be optimized in a particular imaging region of interest by sacrificing the reconstruction of other regions. In a further embodiment, image reconstruction can be implemented region by region, allowing global optimization by spending a longer time in reconstruction.

摘要： An imaging method comprises acquiring an undersampled magnetic resonance partially parallel imaging (MR-PPI) dataset using a plurality of radio frequency receive coils and reconstructing the undersampled MR-PPI dataset to generate a reconstructed magnetic resonance (MR) image. The reconstructing includes: (i) using a generalized auto-calibrating partially parallel acquisition (GRAPPA) operator or direct convolution to fill in at least some missing data of the undersampled MR-PPI dataset so as to generate an enhanced dataset; and (ii) using an algorithm other than a GRAPPA operator and other than direct convolution to reconstruct the enhanced dataset or to reconstruct the undersampled MR-PPI dataset using the enhanced dataset as an initialization dataset for an iterative reconstruction algorithm. In some embodiments the MR-PPI dataset is a non-Cartesian dataset and a GRAPPA operator for wider radial bands (GROWL) is used in the operation (i).

摘要： A medical apparatus (300, 400, 500, 600) includes a magnetic resonance imaging system (301). The medical apparatus further includes a memory (330) containing instructions (350, 352, 354, 456, 458, 460) for execution by a processor (324). Execution of the instructions causes the processor to acquire (102, 202) baseline magnetic resonance data (332) and reconstruct (104, 204) a first image (334) using the baseline magnetic resonance data. Execution of the instructions further causes the processor acquire (106, 212) undersampled magnetic resonance data (336), which is undersampled in k- space in comparison to the baseline magnetic resonance data. Execution of the instructions further causes the processor reconstruct (108, 214) a second image (338) using the undersampled magnetic resonance data and the first image. The second image is reconstructed using an image ratio constrained reconstruction algorithm (354). A temperature map (340) is calculated (110, 216) using the second image.
