摘要： Example apparatus and methods order projections in a 3D MRI acquisition to achieve improved equidistant spacing or to achieve improved adherence to a target distribution. The equidistant or target spacing may exist in k-space and/or in kt-space. In one embodiment, the improved equidistant spacing is a substantially uniform spacing. The substantially uniform spacing may be achieved using a modification of a charge repulsion analysis that treats points of projections that intersect the surface of a 3D volume to be imaged as point charges distributed on the 3D volume. In another embodiment, the target spacing may be uniform, non-uniform, uniform in parts and non-uniform in other parts, and other combinations.

摘要： Systems and methods of writing data to a buffer during a buffer cycle are described. The buffer has a plurality of buffer banks having various fill levels. The buffer determines a first portion of banks from the plurality of buffer banks. The first portion of banks unfilled banks. A rank can be assigned to each of the first portion of banks and a candidate set of banks chosen from the first portion of banks. A target bank is then chosen from the candidate set and the data is written to that bank. The ranking may be random. Furthermore, the target bank can be chosen based on ranking, fill level, or both.

摘要： In a method and apparatus for generating a magnetic resonance image of a contiguous region of a human body on the basis of partial parallel acquisition (PPA) by excitation of nuclear spins and measurement of radio-frequency signals indicating the excited spins, the spin excitation is implemented in steps with measurement of an RF response signal simultaneously in each of a number of N component coils. a number of response signals thus are acquired that, for each component coil, form an incomplete data set (40) of acquired RF signals. Additional acquired calibration data points exist for each incomplete data set. The N incomplete data sets are acquired to a subset of M reduced, incomplete data sets on the basis of an N×M reduction matrix, so that M reduced, incomplete data sets are obtained, M complete data sets are formed on the basis of an N×M reconstruction matrix with the non-measured lines of the M reduced, incomplete data sets being reconstructed from all N incomplete data sets. A spatial transformation of the completed reduced data sets is then implemented in order to form a complete image data set from each completed, reduced data set.

摘要： A magnetic resonance (MR) imaging apparatus and technique exploits spatial information inherent in a surface coil array to increase MR image acquisition speed, resolution and/or field of view. Magnetic resonance response signals are acquired simultaneously in the component coils of the array and, using an autocalibration procedure, are formed into two or more signals to fill a corresponding number of lines in the signal measurement data matrix. In a Fourier embodiment, lines of the k-space matrix required for image production are formed using a set of separate, preferably linear combinations of the component coil signals to substitute for spatial modulations normally produced by phase encoding gradients. One or a few additional gradients are applied to acquire autocalibration (ACS) signals extending elsewhere in the data space, and the measured signals are fitted to the ACS signals to develop weights or coefficients for filling additional lines of the matrix from each measurement set. The ACS lines may be taken offset from or in a different orientation than the measured signals, for example, between or across the measured lines. Furthermore, they may be acquired at different positions in k-space, may be performed at times before, during or after the principal imaging sequence, and may be selectively acquired to optimized the fitting for a particular tissue region or feature size. The in vivo fitting procedure is readily automated or implemented in hardware, and produces an enhancement of image speed and/or quality even in highly heterogeneous tissue. A dedicated coil assembly automatically performs the calibration procedure and applies it to measured lines to produce multiple correctly spaced output signals. One application of the internal calibration technique to a subencoding imaging process applies the ACS in the central region of a sparse set of measured signals to quickly form a full FOV low resolution image. The full FOV image is then used to determine coil sensitivity related information and dealias folded images produced from the sparse set.
