The utility model relates to the field of medicine, biomedical modeling, in particular to phantoms for thyroid research, and can be used in ultrasound imaging laboratories to train specialists in ultrasound diagnostics of the thyroid gland, manipulations with ultrasound navigation, testing equipment and creating new diagnostic techniques and devices. A thyroid phantom [Thyroid Ultrasound Training Phantom. CIRS. https://www.doza.ru/catalog/ultrasound_training_phantoms/2882/], made in the shape of a neck, containing models of the thyroid gland, soft tissue surrounding the gland, trachea, internal jugular vein and common carotid artery as internal anatomical landmarks. The disadvantage of this technical solution is its low detail, caused by the absence of many important anatomical landmarks, such as bones, cartilage, lymph nodes, and vertebral arteries. Unlike this prototype, the proposed utility model contains models of bones, cartilage, lymph nodes, and vertebral arteries. Due to this, greater realism is achieved and the scope of application is expanded. The task to be solved by the claimed utility model is the creation of a phantom for ultrasound research, characterized by realistic modeling and the resulting realistic observation conditions using ultrasound diagnostic tools. The technical result provided by the given set of features is to increase the degree of correspondence of the phantom structure to the structure of the human thyroid gland and the resulting increase in the realism of the conditions for conducting ultrasound experiments for the purpose of training specialists and thereby improving the quality of mastering ultrasound diagnostic techniques and manipulations under the control of ultrasound imaging performed with using a phantom. Working with a phantom will provide skills in differential diagnosis of thyroid nodules, assessment of the size of the thyroid gland and thyroid nodules, and the skill of inserting a needle to take a biopsy sample.
