High Standard Trolley Fully Digital Ultrasound Scanner

Elasticity Imaging in Healthcare

Introduction
Tissue elasticity offers clinically significant information on
tumor and lesion growth, including early state characterization
that may greatly assist early diagnosis. We present
visualization of tissue elasticity through two methods:
1) Freehand elastography using manual probe compression
2) Sound-Push© elastography & shear wave speed
estimation using ARFI

Freehand elastography
Motion tracking of manual compression or breathing
induced movement generates a strain image
representing the elasticity of the underlying tissue. Saset
has one issued patent and our lab in collaboration with
Sichuan University has 17 published academic papers
and 7 PhD theses.

Wave Speed estimation
Saset introduces Sound-Push© elastography, with two pending
patents, which does not require manual compression as it is
based on transmitting high energy pulses to acoustically push
the tissue. This technique results in more accurate strain
images. Moreover, Saset offers shear wave speed estimation
which can diagnosis liver fibrosis diseases quantitatively.

Experimental verification and accuracy analysis
In our lab, we have verified our Sound-Push© elastography using
Model 049, CIRS Elasticity QA phantom, with results between
1.25% and 4.44% error using four types of hard/soft lesions.
Additionally, we verified shear wave speed estimation using
Model 039, CIRS Shear Wave Liver Fibrosis Phantom, with
1.61% to 6.37% error (from 4 to 44.4 kPa Young’s modulus)

State (Beijing) Medical Technology Co., Ltd. established in 2002, is a High-tech medical products enterprise combining R&D, production ,sales and after-sale together, specialized in Medical Ultrasonic Instruments, ENT Workstation, Medical Endoscope Imaging Systems, Colposcope, Spectral Instrument for gynecology, Plasma Air Disinfection Machine, X-ray machines and etc. We constantly develop high-quality electric medical devices by adopting the domestic advanced technical facilities to blend the computer information process technology and clinical medicine research perfectly.

With advanced ultrasonic technology, high-standard quality system, strict production process control and efficient after-sales service, our medical ultrasound products has obtained the trust of many medical institutions, such as Colour Doppler ,Digital B/W Ultrasound, Wireless Mini Ultrasound Scanner. Our Colour Doppler is the advanced scientific research achievement of State, which is the reflection that State has been taking customer's demand as design concept and making excellent technology innovation as backup force whether from scalable structure or high-quality images and powerful clinical application. State supply cost-effective and best image colour ultrasounds to global medical communities and make ultrasonic diagnosis enter into a new level. State has got good social and economic benefits because it pays attention to develop new technology and products, train and introduce high-quality talents.

State has first passed the ISO 13485 certificate and the Quality System Certification of ISO9001 as early as 2004 among the same industry in China. The ISO14001 environmental management system certification and ISO 18001 occupational health and safety management system certification has been obtained in 2012. By the end of 2016, three products of our factory have passed the European CE certification. So far, we have 4 computer software copyrights, 2 invention patents, 18 practical and new patents. We always put "quality-oriented, customer the first" as our tenet and stick to the belief "high-standard product, excellent service". We will explore and develop unceasingly and try to make outstanding contributions to human health in the world, which is the common goal of every State people.
