Ultrasound training phantoms are specialized tools designed to simulate human tissue and anatomy for practicing and perfecting ultrasound techniques and procedures, particularly those involving needle guidance.

The model simulates thyroid module with a realistic skin-colored appearance, accurately replicating ultrasound imaging characteristics. It includes anatomical structures such as thyroid lobes and nearby vessels. The nodules have varying echogenic properties, supporting training in ultrasound image recognition, measurement, and fine needle aspiration biopsy.
