Abstract

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.

超声引导针跟踪新技术：利用闭合电路的廉价可重复使用模型

目的：市面上有多种用于教学目的的超声培训模型。闭合电路与绝缘材料相结合，创造出一种新型模型，可用于在超声引导下反复练习追踪针头。当针头（在超声引导下）接触到镶嵌在模型材料中的三个金属物体之一时，一个三色发光二极管（LED）就会发光。这个原型模型为超声针引导的三维练习提供了一个简单的解决方案，特别适合使用人数较多的项目。该原型模型为教育用模型训练器的新概念提供了一个起点。
