Signa Architect

Description

Overview

The GE SIGNA Architect 3.0T represents the pinnacle of 3.0-Tesla magnetic resonance imaging. Built to meet the demands of advanced radiology practices, oncology centers, and academic research hubs, the SIGNA Architect eliminates performance compromises by integrating high-channel digital hardware with cutting-edge artificial intelligence.

At its core is GE’s 128-channel Total Digital Imaging (TDI) architecture, which digitizes RF signals directly inside the receiver coil to eliminate analog transmission noise. Paired with AIR™ Technology—ultra-lightweight, flexible surface coils that wrap around patients like a blanket—the SIGNA Architect provides exceptional anatomical coverage while virtually eliminating coil weight discomfort. Enhanced by AIR Recon DL, a deep-learning image reconstruction engine, the system removes noise and truncation artifacts directly from raw $k$-space data, enabling ultra-fast, high-resolution scanning.

Key Features & Advanced Technologies

• 128-Channel TDI Direct Digital RF Architecture: Digitizes signals right at the coil element, yielding up to a $27\%$ boost in SNR over traditional analog 3T platforms.

• AIR Recon DL (Deep Learning Reconstruction): AI algorithm trained on tens of thousands of images that systematically eliminates image noise and ringing artifacts, enabling higher spatial resolution with up to $50\%$ shorter scan times.

• AIR™ Coil Suite: Ultra-flexible, blanket-like array coils that are up to $60\%$ lighter than conventional rigid coils. Automatically conforms to all body shapes, supporting feet-first imaging across every scan protocol.

• AIR x™ & AIR Touch™ AI Workflow: AIR Touch™ automates coil selection and element pairing upon landmarking, while AIR x™ uses deep learning to automatically detect anatomical landmarks and slice planes (such as brain and knee exams) for $5\times$ faster setup and reduced operator variability.

• reFINE & deFINE B1 Homogeneity Engine: Advanced dual-source parallel transmit RF control that corrects $B_1$ field non-uniformities, eliminating abdominal dielectric shading and standing-wave artifacts across a full $50\text{ cm}$ Field of View (FOV).

• eXpress Dockable Patient Table: Supports up to $500\text{ lbs}$ ($227\text{ kg}$) with memory foam padding and quick-release egress for continuous, high-volume patient prep outside the scanner room.
