제목 Model040GSE Multi-Purpose Multi-Tissue Ultrasound Phantom












THE NEW STANDARD FOR ULTRASOUND QUALITY ASSURANCE
 
The CIRS Model 040GSE Multi-Purpose, Multi-Tissue Ultrasound Phantom contains nine performance measurements, including gray scale targets, anechoic stepped masses and elasticity targets. The CIRS Multi-Purpose, Multi-Tissue Ultrasound phantom exceeds ACR accreditation requirements, making it the only phantom of its kind designed to meet the ultrasound QA challenges of today and tomorrow.
The unique dual attenuation of the background gel allows for evaluation of transducers that range from 2 MHz - 15 MHz.  A removable water well and endocavity cover extends the use of the phantom by allowing evaluation of all transducer configurations: linear, curvilinear and intercavity.
CIRS ultrasound QA phantoms come standard with a robust housing, rugged carry case, 48-month warranty, and user guide.
