Abstract
For obtaining image information from a subject, in an excitation phase nuclear resonance signals are excited with wavelet-encoding by emitting a radio-frequency pulse under the influence of a gradient in a first direction, the pulse having an envelope that corresponds to the Fourier transforms of a wavelet function. In addition, a layer selection is achieved by the application of an oscillating gradient in a second direction. In a readout phase, a gradient echo signal is sampled under the influence of a readout gradient in a third direction. The pulse sequence can be repeated with a repetition time that is shorter than the longitudinal and transverse relaxation time, so that a steady state arises.
