An implementation of wavelet encoding to resolve one spatial direction of a three‐dimensional gradient‐echo magnetic resonance image is described. This is the first report of the use of wavelet encoding with a relatively short repetition time for rapid image acquisition. An important feature of this implementation is that it allows wavelet‐encoded images to be reconstructed without phase correction. The images show no discernible degradation compared with images acquired with phase encoding or scaling‐function encoding instead of wavelet encoding. In addition to describing the implementation, typical sources of phase errors are investigated both theoretically and experimentally.
