近年来，基于超声图像相关性的无创速度场测量被认为是疾病过程基础研究的一种有前途的技术，也是一种诊断工具。该方法的一个主要缺点是在使用常规超声设备时动态范围相对有限。我们提出了一种方法，它可以在保持全视场的同时，放宽对最大流速的限制。该方法使用传统的硬件，但使用了一种新的读出序列，该序列交织了后续图像。通过改变两幅交织图像之间的偏移量，我们重新引入了帧间时间作为一个参数，该参数可以被优化用于测速。这种新的方法是用一个参照流的体外研究的数据来证明的。
In recent years, non-invasive velocity field measurement based on the correlation of ultrasound images was 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, while still retaining the full field-of-view. The method uses conventional hardware, but a novel read-out sequence that interleaves subsequent images. By varying the offset 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.
