Clear delineation of breast architecture was achieved with compound pulse echo ultrasound imaging in which the images were acquired in the coronal planes used for quantitative transmission ultrasonic computed tomography. Since most connective tissue planes in the breast radiate toward the nipple, compound scans from the sides of the breast record normal interfaces more consistently and reveal greater symmetries in normal portions of relatively full breasts than do conventional scans in sagittal or transverse planes. Simultaneous acquisition of the pulse echo images and images representing the local ultrasound attenuation coefficient and speed of ultrasound suggested complementary role for reflection and through-transmission images in breast cancer detection. The high quality of pulse echo images in coronal planes provides the potential for more complete pulse echo diagnosis and the basis for spatial correlation of lesions viewed in pulse echo and ultrasonic computed tomograms. These observations may permit routine ultrasonic computed tomography of the breast in the clinical setting.
复合脉冲回波超声成像实现了乳腺结构的清晰描绘，其中图像是在用于定量透射超声计算机断层扫描的冠状平面上采集的。由于乳腺中的大多数结缔组织平面都向乳头辐射，因此从乳房两侧进行的复合扫描比矢状面或横断面的传统扫描更能一致地记录正常界面，并且在相对丰满乳房的正常部分显示出更大的对称性。同时采集脉冲回波图像以及代表局部超声衰减系数和超声速度的图像，表明反射图像和穿透传输图像在乳腺癌检测中具有互补作用。冠状平面上高质量的脉冲回波图像为更完整的脉冲回波诊断提供了潜力，并为在脉冲回波和超声计算机断层图中观察到的病变进行空间关联奠定了基础。这些观察结果可能使乳腺超声计算机断层扫描在临床环境中得以常规应用。
