A flow velocity zeugmatographic interlace for NMR imaging in humans.
We describe a flow sensitizing zeugmatographic phase-modulation interlace for NMR-imaging which is exactly analogous to Lauterbur's spatial-location-sensitizing magnetic field gradients. The method may be implemented by minor modification of any NMR-imaging scanner without interfering with its conventional operation, and enables up to 6-D imaging of the joint (spatial-flow) density of spins delta (r,v). In a special simplification, specific-flow-density, mean value of v(r), and flow-current-specific-flow-density, rho 0(r)v, derive directly from "real' and "imaginary" parts of the image reconstruction.
