Abdominal and obstetric applications of a dynamically focused phased array real time ultrasonic system are described. This work was performed utilising both the Thaumascan (two-dimensional, high resolution, actual time, ultrasound, multi-element array scanner) and the first commercial unit based on this system, the Grumman RT-400. Examples of normal and pathological anatomy are presented from over 300 examinations performed to date, including a series of 28 abdominal aortic aneurysms studied with the RT-400. Following electronic alterations in the Thaumascan with resultant improvement in the grey scale, prospective analyses in 86 obstetric and 23 abdominal examinations were undertaken. These studies indicate that fetal, intra-uterine, and abdominal structures can be rapidly and consistently imaged. The value of real time ultrasonic scanning in obstetric and abdominal examinations is illustrated. The principles of dynamically focused phased arrays are described, and the merits and limitations of these systems are discussed.
本文描述了动态聚焦相控阵实时超声系统在腹部和产科的应用。这项工作是利用索马扫描器（二维、高分辨率、实时、超声、多元阵列扫描仪）以及基于该系统的第一台商业设备格鲁曼RT - 400完成的。文中展示了迄今进行的300多次检查中正常和病理解剖结构的实例，包括用RT - 400研究的一系列28例腹主动脉瘤。在对索马扫描器进行电子改造并由此改善灰度后，对86例产科检查和23例腹部检查进行了前瞻性分析。这些研究表明，胎儿、子宫内和腹部结构能够被快速且连贯地成像。文中阐述了实时超声扫描在产科和腹部检查中的价值。描述了动态聚焦相控阵的原理，并讨论了这些系统的优缺点。
