Abstract
A new concept of phase encoding called position‐velocity combined oblique Fourier phase encoding is introduced. It encodes both spatial and velocity information in a single oblique direction in the position‐velocity space. Using this method, two‐dimensional projection images of the three‐dimensional position‐velocity joint spin density distribution along different directions can be obtained. These projection images can provide detailed information on the flow system under study. The imaging of the two‐dimensional projection is less time consuming compared to three‐dimensional Fourier flow imaging and can be easily implemented on a conventional magnetic resonance imaging scannner. © 1990 Academic Press, Inc.
