| 摘 要： | 扩展视野超声成像技术可以利用常规超声成像系统获得观察视野更大的图像,使得医生能够全面了解被成像部位的解剖结构,从而得出更客观和准确的诊断结果.本文给出一种基于PC平台的扩展视野超声成像系统及图像配准和拼接的快速算法.实验证明此算法不仅有较好的成像精度,并且有望实现实时成像.

| Abstract: | Extended field-of-view (EFOV) ultrasound imaging can acquire a full field of vision by using conventional ultrasound system, which can help doctors to make more objective and accurate diagnosis. In this paper, an EFOV system base on PC-based ultrasound device is presented. A fast algorithms of imaging registration and compound are discussed in detail. At last the system design is validated using experimental data proving that preferable image accuracy is achievable. Furthermore, real-time imaging is believed to be feasible. |
