在Piezolith 2300泌尿和胆石粉碎装置中用两个实时B型超声扫描仪作结石的超声定位,并在碎石期间由它们提供连续超声谱的监护。这两个扫描仪都能作90°旋转,以完成纵向和横向截面的扫描。扫描仪能伸展80mm,并用数字显示出来。这样,允许有60～140mm的贯穿深度。变焦距可以用不同 Two real-time B-mode ultrasound scanners were used for the sonographic localization of stones in the Piezolith 2300 urinary and gallstone comminution unit and they were monitored by serial sonography during the gravel. Both scanners can be rotated 90 ° to complete the longitudinal and transverse cross-section of the scan. The scanner can stretch 80mm and display it digitally. In this way, a penetration depth of 60 to 140 mm is allowed. Zoom can be different
