Product Overview:
     The General Multi-Tissue Ultrasound Phantom (054GS) contains grayscale targets and enhanced sensitivity targets that exceed the requirements outlined in the ACR accreditation program. This phantom is made from CIRS' proprietary Zerdine? hydrogel polymer, which is formulated to provide tissue-mimicking properties, including compatibility with harmonic imaging. To maximize the phantom's lifespan, the gel is enclosed in a sturdy ABS plastic housing with a Saran-based laminated membrane.
