The purpose of this study was to investigate the accuracy of ultrasound speckle tracking in various tissues. Results from two-dimensional tissue speckle tracking in liver, muscle, fat, and sponge samples are presented, while keeping other speckle tracking parameters constant. Speckle tracking performance was characterized both in terms of the magnitude of tracking errors and in terms of the percentage of correctly tracked displacement vectors. Speckle tracking in muscle tissue, which contains myofibrils and significant tissue microstructure, produced the highest percentage of correctly tracked vectors and smallest tracking errors relative to other tissues.
本研究的目的是调查超声散斑追踪在各种组织中的准确性。本文呈现了肝脏、肌肉、脂肪和海绵样本的二维组织散斑追踪结果，同时保持其他散斑追踪参数不变。散斑追踪性能通过追踪误差的大小以及正确追踪的位移向量的百分比来表征。相对于其他组织，在含有肌原纤维和显著组织微观结构的肌肉组织中进行的散斑追踪产生了最高百分比的正确追踪向量和最小的追踪误差。
