先前的超声斑点跟踪方法已经被扩展，允许在组织运动的宽动态范围内测量内部位移和应变场。这种方法的动态范围明显增加，应导致应变和弹性图像的对比度分辨率增强。基于明胶的组织等效体模的实验结果表明了该方法的能力。
Previous ultrasound speckle tracking methods have been extended, permitting measurement of internal displacement and strain fields over a wide dynamic range of tissue motion. The markedly increased dynamic range of this approach should lead to enhanced contrast resolution in strain and elasticity images. Results of experiments on gelatin-based, tissue equivalent phantoms show the capabilities of the method.
