Development of an anthropomorphic phantom that can be used for ultrasound guidance evaluation in the management of thyroid nodules.
In order to evaluate and test the various transducers in a controlled setting, phantoms can be used. We develop phantoms with various characteristics to aid us in this evaluation. We have developed an ablation phantom that shows the extent of the ablation area via the use of thermochromic ink, see Figure 3. This allows for a direct comparison of the impact of the transducer on the ablation procedure. This also described in our publication shown below.
We now focus on improving this phantom to include also dynamic characteristics and be anthropomorphic.
