UNASSIGNED: 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.
UNASSIGNED: 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.
■将闭合电路与绝缘材料结合在一起,以创建一种新颖的体模,该体模可用于在重复的场合在超声引导下练习针跟踪。当针(在超声指导下)与嵌入在phatom材料中的三个金属物体之一接触时,三色发光二极管(LED)发光。
■该原型模型为三维超声针引导提供了一种简单的解决方案,特别适合于具有大量用户的程序。这种原型为教育幻影教练的新概念提供了起点。
