OVERVIEW
The Model 040GSE Multi-Purpose,
Multi-Tissue Ultrasound Phantom is
a sturdy, reliable phantom for testing
the imaging performance of ultra-
sonic systems.
The phantom is made of CIRS' pro-
prietary Zerdine
®
hydrogel polymer,
which has been formulated to provide
tissue mimicking properties under
B-mode ultrasound and other fea-
tures such as harmonic imaging. To
maximize phantom lifetime, this gel
is contained in a rugged ABS plastic
housing with a Saran-based laminate
membrane.
The Model 040GSE has two attenu-
ation zones to allow use over the
widest range of transducer types
possible. The high attenuation zone
ensures that even low-frequency
probes (5 MHz and below) do not
penetrate to the bottom of the phan-
tom when measuring penetration
depth. The low attenuation zone al-
lows high frequency probes (greater than 5 MHz) to image key testing targets within
the rst 4 cm of the phantom. This combination allows testing of most transducers
in clinical imaging frequencies from 2 to 20 MHz.
CIRS is certied to ISO 13485:2016 standards. We have an in-house test facility to
measure acoustic properties of materials. In addition, ultrasound imaging systems
are used to inspect each phantom. Every ultrasound phantom that CIRS distributes
has passed thorough testing during manufacture and completion to ensure the
highest quality product available. A Certicate of Compliance is issued with each
phantom.
Additional guidance on establishing a quality assurance program can be found in
the accreditation programs established by the ACR and AIUM at www.acr.org or
www.aium.org.
