Abstract
A new Magnetic Resonance Imaging of flow by a method of successive excitation of a moving slice is presented here. The method, which in general belongs to the Time-of-Flight methods is based upon selectively changing the frequencies in a sequence of rf pulse in such a way that a selected slice moves through the imaged volume in a preselected direction and velocity, and is repeatedly excited. It is claimed that most of the measured signal is contributed by only the parts of the images substance which move with the selected slice. The activation procedure of the flowing spins, which is presented here, enhances the imaging of the flowing matter and reduces the signal from static matter. A specially tailored selective sequence of rf αΔ-pulses has been developed. During this sequence, a set of rephasing 180° selective rf-pulses is applied. At the end of this sequence, an additional 180° selective rf-pulse is applied to eliminate redundant signals from the static matter in the last activated slice.
