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 $\text{Δ}\text{(}\text{r}\text{,}\text{v}\text{)}$. In a special simplification, specific-flow-density, $\text{〈v(}\text{r}\text{)〉}$, and flow-current-specific-flow-density, $\text{?}{}_0\text{(}\text{r}\text{)〈}\text{v}\text{〉}$, derive directly from “real” and “imaginary” parts of the image reconstruction.
