A method for fast recovery of a magnetic resonance image
A method for fast recovery of magnetic resonance images, magnetic resonance signals from an imaging region (FOV) by magnetic gradient fields (34, 36) which define a spatial frequency domain, are conditioned such that the spatial frequency space extending with radially aligned and through a center of projection (44) trajectories with magnetic resonance signals is occupied, characterized in that the imaging region (FOV) in subregions (fov angig of their spatial position in the imaging area (FOV) - are clearly be reconstructed, and in that a transformation step, the received signals of the individual antennae (14A, 14B, 14C, 14D) in consideration of the position (d) ...
The study of rotifer phylogenies and the analysis of population-level processes historically have been disjunct. This is despite a growing recognition that there are many ways in which rotifer population biologists and ecologists might profit from the availability of a comprehensive phylogeny of the group. New molecular methods which can be applied to a wide range of genetic systems and systematic grades will shortly eliminate the methodological (and perhaps conceptual) distinction between these fields. Of particular importance is the development of the Polymerase Chain Reaction (PCR), a technique of synthetic DNA amplification which produces concentrated preparations of selected genes from complex mixtures of nuclear and mitochondrial genomes. Analysis of PCR products can provide hierarchal genetic comparisons from the level of local rotifer populations through broad evolutionary (at least molecular) phylogenies.
