We designed all of our CAE Blue Phantom signature Blue Blocks entirely of our patented Simulex tissue. This model contains a wide variety of foreign bodies, including metal projectile BBs, metal shrapnel fragments, wooden splinters, metal needles, large glass fragments and glass shards, dispersed at different depths and positions. It is ideal for developing and practicing the psychomotor skills for ultrasound proficiency, including using ultrasound system controls, positioning and moving the transducer, recognizing a wide variety of foreign bodies in soft tissue, targeting the foreign bodies, and retrieving them. The Simulex tissue has self-healing properties, allowing for 1000+ punctures when used with an 18-21 gauge needle.
