Although ultrasound examination became almost indispensable in prenatal diagnosis as well as in gynecological examination, there are still a lot of deficits in the quality management of medical education. We present a "ultrasound simulation system", that makes it possible to simulate a complete ultrasound examination. The system is able to simulate all imaginable kinds of ultrasound examination.
At the Department of Gynecology and Obstetrics of the "Medizinische Hochschule Hannover" 115 banks of normal and 29 banks of pathologic volumes were scanned and stored into our newly developed "ultrasound simulation system". 7 physicians had to examine 10 "virtual" cases each; we evaluated the incidence of positive and negative results. Furthermore, the physicians had to evaluate the quality of visualization with a score.
12 of 14 malformations were identified as "fetal anomalies", whereas 2 fetal anomalies could not be identified correctly. All 56 healthy fetuses could be identified to be normal. The quality of visualization was regarded to be good in 62 cases, sufficient in 6 cases and poor in 2 cases.
The "ultrasound simulation system" enables users to test and improve their levels of skill to detect pathologic findings in gynecological and obstetrical examinations. At the same time the system gives the instructor the possibility to test the quality of medical examinations. The integration of ultrasound training with an ultrasound simulation system into medical education should be discussed to improve the general level of skill in gynecological ultrasound.
尽管超声检查在产前诊断以及妇科检查中几乎不可或缺，但医学教育质量管理仍存在诸多不足。我们展示了一种“超声模拟系统”，它能够模拟完整的超声检查。该系统能够模拟所有可想象到的超声检查类型。
在汉诺威医学院妇产科，对115份正常病例组和29份病理病例组进行扫描，并存储到我们新开发的“超声模拟系统”中。7名医生每人必须检查10个“虚拟”病例；我们评估了阳性和阴性结果的发生率。此外，医生们必须用评分来评估可视化质量。
14例畸形中有12例被识别为“胎儿异常”，而2例胎儿异常未能正确识别。所有56例健康胎儿均被识别为正常。可视化质量被认为良好的有62例，足够的有6例，差的有2例。
“超声模拟系统”使使用者能够测试和提高他们在妇科和产科检查中检测病理结果的技能水平。同时，该系统使教师能够测试医学检查的质量。应讨论将超声训练与超声模拟系统整合到医学教育中，以提高妇科超声的总体技能水平。
