Abstract
Methods for quantitative flow rate measurements (“velocimetry”) without spatial resolution have already been suggested before imaging techniques became known [376, 453]. Nowadays phase-encoding techniques [32, 130, 339, 348, 356, 399, 490] are standard for spatially resolved representations. A review of applications can be found in [82].

Note
From a more operational point of view, three independent, four-dimensional experiments, one for each velocity component, are more favorable than a single six-dimensional conduct of the measurement. A six-dimensional experiment in the proper sense would involve encoding of six quantities in each transient, i.e., five independent phase-encoding increments would be required. Fortunately a series of three four-dimensional experiments is equivalent to such an extremely time-consuming procedure as long as spatial and velocimetrical encoding are independent from each other, as it usually is the case.
