    摘要: A method for time-resolved imaging of N-dimensional magnetic resonance (=MR) with the following steps: Acquisition of MR signals from a sample volume by parallel imaging, wherein N-dimensional data matrices (M1, M2, . . . MNt) in k-space is acquired undersampled from each receiver coil, wherein the acquisition of the MR signals is performed according to an acquisition scheme that is periodic over time and describes the time sequence of the undersampled data matrices (M1, M2, . . . Mn) and reconstruction of missing data points (FP) of the acquisition scheme using a set of coil weighting factors (CW, ) and using N+1-dimensional reconstruction kernels (RK, RK′ RK″) is characterized in that reconstruction of the missing data points (FP) is performed using a single reconstruction geometry, wherein each reconstruction kernel comprises an (N+1)-dimensional target area (TB), wherein all non-acquired data points (TP) are reconstructed within the associated target area (TB) using each reconstruction kernel (RK, RK′ RK″), and wherein the target area (TB) exhibits at least the extent (nR×mR) in the ky-t plane of the acquisition scheme. This can shorten the computation time for reconstruction and reduce reconstruction artifacts and optimize the signal-to-noise ratio.

    摘要: A four-cylinder, reciprocating piston-machine includes a crankshaft having a rotary axis; a center bearing supporting the crankshaft; two outer bearings flanking the center bearing and supporting the crankshaft; and first, second, third and fourth torsion springs extending parallel to the crankshaft axis. The first and second torsion springs are parallel to and facing a first side of a reference plane containing the crankshaft axis, while the third and fourth torsion springs are parallel to and facing a second side of the reference plane. First, second, third and fourth elongated balancing masses are secured to and extending unidirectionally from respective first, second, third and fourth torsion springs toward the crankshaft in a perpendicular orientation to the crankshaft axis. The first and second balancing masses are situated at the outer bearings, while the third and fourth balancing masses are situated at the center bearing. First, second, third and fourth control cams are keyed to the crankshaft and are in engagement with the respective first, second, third and fourth balancing masses for oscillating the balancing masses toward and away from the crankshaft axis to exert varying torques to the respective torsion springs.
