摘　　要：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。A new scanning mode is proposed that the front-end of the probe is fixed, while the back-end makes fan-shaped, scanning movement. The new scanning mode avoided ribs drawbacks successfully, based on the new scanning mode a 3D-Ultrasound Images System is accomplished to acquire 2D data of fetusfetus fetusfetus phantom and livers and kidneys, to demonstrates the effectiveness of the new scanning mode.
