Description
Overview
The Siemens MAGNETOM Avanto Fit 1.5T offers healthcare facilities a cost-effective path to acquiring modern 1.5-Tesla MRI performance. By retaining the reliable, high-homogeneity OR105 magnet frame, the “Fit” upgrade replaces legacy RF receivers, gradient amplifiers, control electronics, and user interfaces with Siemens’ state-of-the-art Tim 4G and syngo MR platforms.
At the core of the Avanto Fit’s performance is Tim 4G DirectRF technology. By digitizing signals directly at the receiver components, the platform eliminates signal loss over long cable runs, increasing Signal-to-Noise Ratio (SNR) by up to $40\%$. Combined with ultra-lightweight DirectConnect cable-free coils, the DotGO workflow engine, and Quiet Suite acoustic noise reduction, the Avanto Fit provides fast exam turnaround, high diagnostic confidence, and a quiet, patient-friendly environment.
Key Features & Advanced Technologies
-
Tim 4G Integrated RF System: Features up to 64 independent receive channels and up to 204 integrated coil elements. Cable-free DirectConnect coils simplify technologist positioning and dramatically reduce set-up times.
-
DotGO Engine Automation: Guided software architecture that standardizes scan protocols and automates slice alignment via predefined Dot Engines (GOBrain, Spine Dot, Cardiac Dot, etc.).
-
SQ Engine Gradients ($45\text{ mT/m}$ / $200\text{ T/m/s}$): High-amplitude, high-slew-rate gradient performance designed for dynamic sequence execution, short $TE/TR$ timing, and high spatial resolution.
-
Quiet Suite Noise Suppression: Hardware and software acoustic dampening technology that achieves up to $97\%$ reduction in sound pressure levels during neuro and musculoskeletal acquisitions without affecting contrast or detail.
-
FREEZEit Free-Breathing Motion Suppression: Advanced body sequences (TWIST-VIBE and StarVIBE) that permit free-breathing, dynamic contrast-enhanced liver and abdominal studies in uncooperative or pediatric patients.
-
Eco-Fit Upgrade Advantage: Extends system longevity by upgrading the RF/electronics cabin in as little as 10 to 15 working days, bypassing heavy structural construction or room wall removals.
