Simulation of ultrasound data is often performed for developing new ultrasound data processing techniques. The spatial impulse response method (as implemented in FieldII) has typically been used as the gold standard due to its excellent accuracy in the linear domain. When scatterer numbers become significant and when 3D volumetric data sets need to be computed, calculation time can become an issue however. In order to solve this problem, two alternative methods have recently been proposed both of which are based on the principle of convolving a set of point scatterers with a point spread function. "FUSK" operates in the frequency domain while "COLE" runs in the spatio-temporal domain. The aim of this study was to directly contrast both methodologies in terms of accuracy and processing speed using FieldII as a reference.
超声数据的模拟常用于开发新的超声数据处理技术。由于其在线性域中的出色准确性，空间脉冲响应方法（如 FieldII 中实现的方法）通常被用作黄金标准。然而，当散射体数量变得显著并且需要计算 3D 体积数据集时，计算时间可能会成为一个问题。为了解决这个问题，最近提出了两种替代方法，它们都基于用点扩散函数卷积一组点散射体的原理。“FUSK”在频域中运行，而“COLE”在时空域中运行。本研究的目的是使用 FieldII 作为参考，直接比较这两种方法在准确性和处理速度方面的差异。
