Discovery MR-750w

Description

Overview

The GE Discovery MR750w 3.0T sets a benchmark for 3.0T magnetic resonance imaging by combining high-end clinical capabilities with wide-bore patient comfort. Traditionally, 3T MR systems faced challenges with $B_1$ field inhomogeneity (shading artifacts) and patient claustrophobia. The Discovery MR750w solves both issues simultaneously by pairing a short, $70\text{ cm}$ flared wide-bore design with MultiDrive RF technology—GE’s multi-channel parallel RF transmit system that automatically adjusts excitation phases and amplitudes for uniform tissue signal.

Integrated with OpTix Optical RF Architecture, which converts analog signals to optical signals directly inside the scan room, the MR750w delivers exceptional Signal-to-Noise Ratio (SNR) for ultra-thin 3D acquisitions, functional MRI (fMRI), diffusion tensor imaging, and body imaging.

Key Features & Advanced Technologies

• 3.0T Wide-Bore Design ($70\text{ cm}$): Designed to accommodate claustrophobic, bariatric, and pediatric patients without compromising the extreme resolution and spectral separation inherent to 3T imaging.

• MultiDrive RF Parallel Transmit: Uses independent RF transmit source control to homogenize the $B_1$ field across large fields of view, eliminating abdominal dielectric shading and signal drop-out common in standard 3T MRIs.

• eXtreme Gradient Performance: Delivers $50\text{ mT/m}$ gradient amplitude and a $200\text{ T/m/s}$ slew rate across all 3 axes simultaneously, driving fast, high-resolution $2\text{D}$ and $3\text{D}$ clinical sequences with minimal echo spacing.

• OpTix Digital Optical RF: Direct optical signal conversion inside the scan room reduces electronic noise, enhancing overall SNR by up to $27\%$ compared to traditional analog receivers.

• GEM (Geometry Embracing Method) Suite: Ultra-lightweight, high-density RF coils that contour naturally around patients to maximize surface SNR while enhancing patient comfort.

• IntelliTouch Patient Setup: Streamlines workflow by letting technologists position patients and align the laser in seconds with a simple touch on the table side.
