Magnetom Avanto

Description

Overview

The Siemens MAGNETOM Avanto 1.5T remains one of the most successful and reliable workhorses in magnetic resonance imaging, establishing high standards for image consistency and diagnostic breadth. Featuring an ultra-short $150\text{ cm}$ magnet length and a patient table that lowers to just $47\text{ cm}$ ($18.5\text{ inches}$), the Avanto offers easy access for pediatric, geriatric, and mobility-impaired patients while minimizing claustrophobic responses.

At the core of the MAGNETOM Avanto is Siemens’ Tim (Total Imaging Matrix) technology. Tim allows operators to combine up to 76 matrix coil elements across multiple body regions simultaneously, enabling complete head-to-toe scans of up to $205\text{ cm}$ without forcing patient repositioning or manual coil swaps. Driven by the SQ Engine high-performance gradient system and syngo user interface, the Avanto excels in demanding applications such as cardiac cine imaging, high-resolution neuro-vascular mapping, and body oncology.

Key Features & Advanced Technologies

• Tim (Total Imaging Matrix) Technology: Integrates high-density matrix coil elements into seamless multi-coil combinations. Enables flexible imaging of single anatomical regions or whole-body acquisitions without coil changes.

• SQ Engine Gradients ($45\text{ mT/m}$ / $200\text{ T/m/s}$): High-amplitude, high-slew-rate gradients designed for demanding sequence timing, providing ultra-short $TE/TR$ values required for high-resolution cardiac, diffusion, and functional imaging.

• AudioComfort Acoustic Noise Reduction: Suppresses acoustic gradient noise levels by up to $30\text{ dB}$ ($97\%$ sound pressure reduction) at the hardware and sequence level, enhancing patient compliance without degrading gradient output.

• syngo User Interface & iPAT: Streamlined operational interface featuring integrated parallel acquisition techniques (iPAT) that significantly shorten acquisition times and reduce motion artifacts.

• TimCT (Continuous Table Move): Allows continuous table movement during data acquisition, producing smooth, seamless whole-body angiographic and oncological screening images.

• Zero Helium Boil-Off Magnet: Advanced cryostat housing preserves liquid helium levels under normal operation, reducing routine maintenance expenses and operational overhead.
