Fraser, K.H. Faculty Mechanical, Maritime and Materials Engineering Department Process Energy Date 2013-07-02 Abstract In recent years, non-invasive velocity field measurement based on correlation of ultrasound images has been introduced as a promising technique for fundamental research into disease processes, as well as a diagnostic tool. A major drawback of the method is the relatively limited dynamic range when conventional echography equipment is used. We present a method by which the restriction of the maximum flow rates can be relaxed. The method uses conventional hardware, but a novel read-out sequence that interleaves subsequent images. By varying the off-set between two interleaved images, we re-introduce the inter-frame time as a parameter that can be optimized for velocimetry. The novel approach is demonstrated with data from an in vitro study of a reference flow.
