Novel technique for ultrasound-guided needle tracking: An inexpensive reusable phantom model utilising a closed electrical circuit.

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.
