BioSpin MRI New AVANCE™ II MRI Spectrometer Series Offers Signal-to-Noise
Performance Increase
Basel,
Switzerland, Sep. 15: Bruker BioSpin MRI GmbH introduces its new
and revolutionary MRI system, the AVANCE II, at the European Society for
Magnetic Resonance in Medicine and Biology’s
22nd Annual Meeting. Its scalable receiver and transmitter architecture
will enable new MRI applications in preclinical research and molecular imaging.
A four-fold increase in digital resolution
results in an unmatched dynamic range which, in combination
with multi-array rf coil technologies, raises signal-to-noise ratios to
unsurpassed levels. An order of magnitude
increase in digital receiver bandwidth speeds up acquisition times and
provides MRI image quality that could previously not be obtained.
Bruker BioSpin pioneered the first-generation digital receiver technology in the
1990s as part of its NMR digitalization
initiative with the introduction of the novel AVANCE platform. For
the first time, the AVANCE featured innovative digital receiver technology for
oversampling, digital filtering and digital
quadrature detection, now a standard in MRI technology.
In vivo researchers using the new
Avance II will benefit from compelling performance advantages
in all areas of MRI and MRS: A scalable
receiver architecture which supports phased array and parallel imaging technology
with state-of-the art applications (such as ‘GRAPPA’). The scalable multi-
transmitter architecture allows ‘Transmit SENSE’
technology for fast 2D excitation and homogeneous
RF penetration even at ultra-high magnetic fields.
The Avance II architecture allows further
expansion of channels in the future. A
four-fold higher digital resolution and high dynamic range preamplifiers provide
optimum detection sensitivity of all k-space
regions, resulting in superb contrast and SNR in
3D imaging. An order of magnitude increase in
digital filtering bandwidth up to 5 MHz with faster digitization
rates and faster over-sampling shortens acquisition times and reduces geometric
image distortions and susceptibility effects (such as in single-shot EPI).
"For in vivo MRI and MRS, the new AVANCE II, with its scalable
receive and transmit channel architecture,
underlines our continuing commitment to providing our customers with the most
advanced imaging technology," commented Dr.
Bernd Gewiese, Managing Director of Bruker BioSpin
MRI.
"New developments such as single-shot EPI, GRAPPA and Transmit SENSE
benefit from our new AVANCE II technology and lead
to high quality images which clearly surpass
those of previous generation MRI systems."
