摘　　要：为探讨静态结构三维超声成像的基本方法和临床应用前景，本研究对１３５例各种不同病例的有关脏器或病变进行了三维图像重建。采样方式包括机械驱动平行扫查和扇形扫查以及磁场空间定位自由扫查。结果表明三维超声成像在以下方面显示出其临床应用价值：①对含液性结构和病变可显示其立体形态，内部结构和内壁特征；②对被液体环绕的结构和病变，可清楚显示其表面特征；③采用连续平行切割，灰阶阈值调节或透明成像等方法显示实质性脏器内部结构的形态和空间位置关系；④利用血流的彩色多普勒能量信息显示正常组织或病变的血管结构和立体形态及其与周围结构的空间位置关系。因此，三维超声成像可为疾病的诊断或治疗提供更加丰富的信息。To evaluate the clinical value of threedimensional (3D) ultrasonic reconstruction, the 3D images were reconstructed in related structures or organs in 135 patients with different diseases. The mechanically driven scanning (including parallel and fan scanning) and freehand scanning were used for data aquisition. The results showed that the 3D ultrasonic reconstruction will be clinically valuable in the following aspects: ①3D demonstration of the organs or structures containing fluid; ②surface depiction of the organs or stuctures surrounded by the fluid; ③the structures in the parenchymal organ can be reconstructed or observed by continuously parallel cutting of the volume data, adjusting the threshold of the gray scale or using transparent imaging technique; ④3D demonstration of the vascular structures and its spacial (anatomical) relationship with the other adjecent structures by using color Doppler energy.
