PURPOSE
Purpose:There are a variety of commercially made ultrasound training phantoms available for educational purposes. A new concept in phantoms is presented that utilises a low-cost method to create a reusable phantom.
METHODS
A closed electric circuit was combined with insulating material to create a novel phantom that can be used to practise needle tracking under ultrasound guidance on repeated occasions. A tricolour light-emitting diode (LED) illuminates when the needle (under ultrasound gudiance) contacts one of three metal objects embedded in the phatom material.
CONCLUSION
This prototype model provides a simple solution for trianing ultrasound needle guidance is particularly geared towards programmes with a high volume of users. This protoype provides a starting point for a new concept in educational phantom trainers.
目的
有多种用于教育目的的商用超声训练体模。本文提出了一种体模的新概念，即利用低成本方法制作可重复使用的体模。
方法
将闭合电路与绝缘材料相结合，制作出一种新型体模，可用于在超声引导下反复练习针追踪。当针（在超声引导下）接触到嵌入体模材料中的三个金属物体之一时，三色发光二极管（LED）会发光。
结论
该原型模型为超声针引导训练提供了一个简单的解决方案，特别适用于用户量大的项目。这个原型为教育体模训练器的新概念提供了一个起点。
