The use of a new 3D ultrasound system should reduce the drawbacks of former 3D workstations (long image generation time, limited use due to the need for special 3D transducers), so that it is now applicable in daily clinical routine.
An ultrasound 3D workstation was used based on a pentium PC platform, employing a magnetoelectronic position detection system for spatial reconstruction of conventional 2D B-scan image sequences.
Better assessment of topographico-anatomical spatial relationships was achieved when presenting pathological findings, especially in assessing lymph nodes and salivary stones. Pathological processes in the maxillofacial area occurring during a period of five months were visualised.
The method of 3D reconstruction of standard two-dimensional electronic scans, as presented here, is the first method of its kind enabling applicability in daily clinical routine thanks to rapid imaging. The images can be produced with any ultrasound unit or transducer. First clinical results in maxillofacial surgery clearly show improved diagnostic possibilities although there still room for an improvement of the image quality. The possibility of semi-automatic exact volumetry appears meaningful especially in the investigation of lymph nodes. Integration of colour duplex sonography will further enhance the diagnostic value of this method.
新型三维超声系统的应用应能减少以往三维工作站的缺点（图像生成时间长、因需要特殊三维换能器而使用受限），从而使其现在可应用于日常临床工作。
使用基于奔腾PC平台的超声三维工作站，采用磁电子位置检测系统对传统二维B超图像序列进行空间重建。
在呈现病理结果时，尤其是在评估淋巴结和涎腺结石时，能更好地评估地形解剖学空间关系。可视化了五个月期间颌面区域发生的病理过程。
本文介绍的标准二维电子扫描三维重建方法是同类方法中的第一种，由于成像快速，使其能够应用于日常临床工作。可以使用任何超声设备或换能器生成图像。颌面外科的初步临床结果清楚地表明诊断可能性有所提高，尽管图像质量仍有改进空间。半自动精确容积测量的可能性尤其在淋巴结检查中似乎很有意义。彩色双功能超声的整合将进一步提高该方法的诊断价值。
