Abstract
In this paper, we describe how the resolution integral can be used as a tool for characterising the grey-scale imaging of diagnostic ultrasound scanners. The definitions of resolution integral, characteristic resolution and depth of field are discussed in relation to grey-scale imaging performance, together with a method of measuring these parameters using the Edinburgh Pipe Phantom. We show how the characteristic resolution and depth of field can be used to quantify the differences between transducers designed for different applications and how they are useful in identifying and quantifying changes in the performance of individual transducers.
摘要
在本文中，我们描述了分辨率积分如何用作表征诊断超声扫描仪灰度成像的工具。讨论了分辨率积分、特征分辨率和景深的定义与灰度成像性能的关系，以及使用爱丁堡管道体模测量这些参数的方法。我们展示了特征分辨率和景深如何用于量化为不同应用设计的换能器之间的差异，以及它们如何有助于识别和量化单个换能器性能的变化。
