基于后端扫描的三维超声成像系统

摘要

A new scanning mode is proposed that the front-end of the probe is fixed, while the back-end makes fan-shaped,rnscanning movement. The new scanning mode avoided ribs drawbacks successfully, based on the new scanning moderna 3D-Ultrasound Images System is accomplished to acquire 2D data of fetusfetus fetusfetus phantom and livers andrnkidneys, to demonstrates the effectiveness of the new scanning mode.%提出了一种将探头前端固定,后端以恒定速度进行扇形扫描的扫描方式,可有效避免肋骨的遮挡.基于此扫描模式,搭建了一套三维超声成像系统,采集了胎儿体模和人体肝肾脏二维数据,证明了该扫描模式的有效性.
