The SONOtrain Breast model with cysts is a realistic reproduction of a breast made from ultrasound material with two cysts for realistic punctures and aspirations. The material of the SONOtrain trainer simulates the feel of real soft tissue for carrying out palpations and injections and shows realistic texture and echogenicity on ultrasound images. The SONOtrain trainer is easy to use as a teaching tool for basic training and for improving dexterity and hand-eye coordination skills.
