We designed this CAE Blue Phantom training block entirely of our patented Simulex tissue. Use this model to develop, practice and maintain the skills necessary to perform ultrasound-guided fine-needle biopsies of the thyroid gland. Learn to use ultrasound system controls, position and move the transducer, recognize the thyroid and surrounding structural anatomy, identify a variety of masses present in the thyroid gland, use ultrasound system calculation packages, and target the lesions for fine-needle biopsies. The Simulex tissue has self-healing properties, allowing for 1000+ punctures when used with an 18-21 gauge needle.
