Development of an ultrasound training phantom of the thyroid gland: physical characteristics of TMM.

The objective of this research was to synthesize a thyroid phantom with ultrasound properties similar to those of tissue-mimicking materials (TMM). This was done so that an ultrasound thyroid-training phantom could be developed. A polymer urethane TMM was made by using the following materials: C, CCR, TiO(2), silver, tungsten, and graphite, in the hope that it would have the same properties as soft tissue.
