Product Information
Based on Acuson’s proprietary technologies, the Acuson Sequoia 512 platform
stablishes
an entirely different category for ultrasound performance, with major advances
in all system operations and performance modes. Its unique use of ultrasound
physics will allow you to see aspects of anatomy and physiology like never before.
As the Acuson Sequoia platform sets new standards, it advances ultrasound to
a new level of diagnostic confidence, with the ability to explore and expand
clinical capabilities. The unrivaled performance of the Acuson Sequoia platform
is based on four technology cornerstones. To understand these technologies is
to appreciate just how far this platform has advanced the science of ultrasound.
Acuson’s proprietary Coherent Imaging Technologies have completely revolutionized
the way ultrasound echoes are transmitted, received and processed. They provide
an unprecedented amount of new information in every image, making it possible
to see anatomy and physiology never seen before with ultrasound.
Coherent Pulse Formation
Marks the first time the transmitted ultrasound waveform has been precisely
controlled to push the boundaries of imaging performance. Through Precision
Pulse Shaping,
exacting transmitter control is used to generate complex transmitted waveforms.
Thus, imaging performance can be optimized in all applications. Coherent Pulse
Formation enables Native® Tissue Harmonic Imaging and several new system
capabilities, with the
promise of even more advancements to come.
Chirp Coded Excitation provides extraordinary penetration
and resolution at high frequencies.
Dynamic Transmit Focus utilizes a single transmit firing
to dynamically focus the transmitted sound beam at multiple focal depths throughout
the image with high frame rates.
Coherent Image Formation uses both phase and amplitude
information to form an image. Subtle tissue contrast differences become immediately
apparent. There’s more
information at depth—even at high frequencies. The definitive gold standard
in imaging performance results in:
A dramatic increase in temporal and spatial resolution.
Greater dynamic range and system sensitivity.
Increased frame rates for better visualization of dynamic structures.
To tap the full potential of the Acuson Sequoia platform, many new transducer
technologies have been developed. The resulting designs, using the latest acoustic
ceramic materials and advanced manufacturing processes, provide increased sensitivity
and resolution which yield more clinical information and expanded applications.
These ergonomically designed transducers provide easier imaging access, increased
operator
comfort and greater clinical impact across all patient types.
Hanafy Lens Transducer Technology provides wide-bandwidth
imaging with a tightly controlled sound beam slice thickness throughout the
entire imaging plane. This clearly
differentiates near-field structures with higher resolution, reduces far-field
beam spread and improves 3-D imaging.
MICROSON™ High Resolution Transducers, such as the 15L8w,
15L8 and EC-10C5, provide exceptionally high resolution, as fine as 200 microns
in gray scale, and
highly sensitive color Doppler, enabling superb breast, musculoskeletal, small
parts, and
first trimester imaging.
MultiHertz® Multiple Frequency Imaging allows users to
select from an expanded range of frequencies to optimize penetration and resolution
in all clinical applications.
microCase™ Transducer Miniaturization Technology provides
significant reduction in transducer case and cable size, optimizing ergonomic
form factors. Fully integrated into the Acuson Sequoia platform, the DIMAQ workstation
offers image and data management, real-time image processing and advanced display
options. Its powerful digital architecture enables storage of complete, digitally
preserved exams, comprised of static and dynamic clip images and calculations.
Since exams are saved in a JPEGcompressed DICOM format, accessing them is fast
and easy. They can be transferred to the KinetDx® family of products or
any ultrasound-compatible PACS, review workstation or web browser, at any time
for efficient review at remote
locations.
The DIMAQ workstation has direct access to all exam data and
offers real-time image processing such as DELTA® differential echo amplification.
It also enables other
special applications, including:
On-board digital image and data management
A full suite of DICOM capabilities
Advanced calculations
Staged protocols for complicated exams, such as contrast agent imaging
and stress echo
Perspective® Advanced Display Option
The Perspective Option provides the foundation for existing
and future applications of extended field-of-view imaging for static and dynamic
studies and a wide array of 3-D imaging displays. A new level of workflow efficiency
is achieved through the ability to easily review digital dynamic studies, capture
and analyze patient data and quickly process patient reports. The Acuson Sequoia
platform empowers clinicians to optimize
image quality in every application, simply and quickly. The subtlest pathology
becomes clearer. There is considerably more anatomical detail in every image.
Clinicians can make diagnoses simpler, faster and with more confidence than
ever before.
=TEQ™ Technology is a sophisticated signal-processing
technology that automatically
equalizes tissue gain and brightness in two dimensions, providing consistent,
eproducible image quality in 2-D and M-mode— all at the touch of a button.
Tissue Equalization Technology is a pre-processing technology, applied to RF
echo data before the image
is formed. It produces consistent, high-quality studies, with more time to focus
on the patient. Tissue Equalization Technology is easy to use and affords higher
productivity
and a dramatic reduction in interoperator variability.
Native® Tissue Harmonic Imaging (NTHI) is a patented method
of harmonic imaging that works by detecting subtle harmonic echoes generated
within tissue while completely rejecting fundamental frequency echoes used in
traditional ultrasound imaging. This essentially eliminates body wall artifacts
and acoustic noise, resulting in more definitive
diagnoses.
Transmit Compounding combines multiple transmitted images
utilizing different
ultrasound frequencies into a single, compounded image. This significantly improves
contrast and detail resolution and reduces image artifacts such as speckle,
noise,
edge shadow and clutter. The result is better differentiation of subtle lesions
and improved visualization of borders and interfaces.
Cadence™ Contrast Agent Imaging. Extensive scientific
and clinical investigations worldwide indicate that the Acuson Sequoia platform
is the premier system for contrast imaging. The success of Cadence contrast
imaging is attributable to innovations in
Coherent Pulse Formation, Tissue Equalization Technology and the digital dynamic
clips enabled by the DIMAQ workstation. Acoustic energy uniformity is enhanced
by means of Dynamic Transmit Focusing and proprietary Hanafy Lens Transducer
technology.
Cadence contrast imaging provides new methods for contrast agent detection,
including extremely effective bubble preservation algorithms. Unique emission
technologies allow clinicians to display the tissue image, the contrast-agent-only
image, or both together—all from the same acquisition dataset.
SST™ Color and Solo™ Spectral Doppler. The unique
architecture of the Acuson Sequoia platform sets a new standard for Doppler
sensitivity and resolution. SST
Color Doppler utilizes multiple beam formers to produce images with high spatial
resolution, high frame rates and unprecedented sensitivity to low flow. Solo
Spectral
Doppler uses a dedicated audio beam former to achieve a new degree of sensitivity
and clarity with superb low flow detection and increased penetration for detection
of deep flow dynamics.
