Bruker BioSpin MRI introduced its revolutionary MRI system, the Avance II, at the European Society for Magnetic Resonance in Medicine and Biology's 22nd annual meeting in September 2005
The Avance II's 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 multitransmitter 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 5MHz 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 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."
