MRI Performance & Image Quality

The SIGNA Architect combines a superconducting magnet, high-performance gradients, and digital signal acquisition for detailed anatomical imaging. These technologies support routine examinations and specialized clinical applications, including neurological, musculoskeletal, and body studies.

3T Magnet & High-Resolution Imaging

The scanner uses a 3.0 Tesla superconducting magnet designed for whole-body MRI.

Its high magnetic field strength supports detailed visualization of the brain, spine, joints, and soft tissue. It also provides the imaging performance needed for advanced diffusion, vascular, and neurological examinations.

The system offers a maximum field of view of 50 × 50 × 50 cm (19.7 × 19.7 × 19.7 in). This extended imaging coverage helps accommodate larger anatomical regions and off-center structures such as shoulders and hips.

Compatible image correction technologies also help maintain image uniformity and anatomical accuracy across the field of view.

Gradient Performance

The SIGNA Architect features gradients rated at 44 mT/m with a maximum slew rate of 200 T/m/s.

Gradient amplitude influences how precisely the scanner locates signals within the body, while slew rate measures how quickly those gradients can change.

Together, these capabilities support high-resolution anatomical imaging, diffusion studies, and advanced MRI sequences that require rapid gradient switching.

Digital RF System & Coil Performance

The scanner features GE’s Total Digital Imaging (TDI) technology with a 128-channel receive architecture.

The radiofrequency (RF) system collects signals from coils positioned around the patient and processes those signals into the data used to create MRI images.

Its digital architecture supports multichannel signal acquisition, detailed anatomical coverage, and compatible accelerated imaging techniques.

The number of receive channels represents the system’s signal-processing capacity rather than the number of elements in an individual coil. Architect configurations may also feature different RF hardware, including 96-channel variants.

 

Patient Access & Exam Experience

The SIGNA Architect’s 70 cm wide-bore design combines additional patient space with flexible coil technology and positioning options. These features help accommodate different body types, examination requirements, and mobility needs.

70 cm Wide Bore & Feet-First Imaging

The scanner features a 70 cm (27.6 in) bore, providing approximately 10 cm (3.9 in) more diameter than traditional 60 cm MRI scanners.

The additional space helps accommodate patients with broader body dimensions and examinations requiring specialized coil arrangements.

Compatible configurations also support feet-first imaging across a broad range of examinations, reducing the need for patients to enter the scanner head-first when clinically appropriate.

Dockable eXpress Patient Table

The SIGNA Architect supports the dockable eXpress Patient Table, allowing patients to be prepared and positioned outside the scanner before the table is docked for imaging.

The eXpress table supports a maximum patient weight of 500 lb (227 kg) in the applicable configuration.

The detachable design provides flexibility for patient transfers and specialized examinations. Compatible IntelliTouch controls also simplify patient positioning through touch-sensitive operation.

Alternative table configurations support specialized surgical-suite and radiation oncology workflows, with weight capacities and positioning specifications varying by configuration.

Flexible AIR Coils & Patient Comfort

GE AIR Coils use lightweight, flexible construction that conforms to patient anatomy rather than relying entirely on rigid coil housings.

This allows compatible coils to fit more naturally around the imaging area, improving positioning flexibility while reducing unnecessary bulk around the patient.

Additional patient-focused technologies include:

• • 48-Channel Head Coil: Accommodates a range of patient head sizes while supporting detailed neurological imaging.
  • Auto Navigator: Tracks respiratory motion without a separate external breathing sensor, supporting free-breathing examinations.
  • Accelerated Imaging: Compatible acquisition and reconstruction technologies shorten selected sequences, reducing the time patients need to remain still.

Exam Setup & Scan Automation

SIGNA Works includes anatomy-specific imaging applications and protocol tools that help technologists prepare and perform MRI examinations.

Available workflow technologies include:

• • AIR Touch: Automatically identifies appropriate coil elements based on patient positioning and the selected imaging area, reducing manual coil selection during supported examinations.

  • Auto Navigator: Tracks respiratory motion during scanning, supporting free-breathing abdominal imaging without requiring an external respiratory sensor.

Together, these technologies help simplify examination setup and reduce repetitive operator steps when included in the installed configuration.

Image Reconstruction & Scan Acceleration

The system supports advanced imaging technologies designed to improve image quality, reduce motion artifacts, and accelerate compatible examinations.

• • AIR Recon DL: Uses deep-learning reconstruction to reduce image noise and improve sharpness. On compatible systems, it can support shorter acquisitions or higher-resolution imaging while maintaining useful image detail.
  • HyperSense: Accelerates selected MRI sequences by acquiring less scan data and using advanced reconstruction methods to complete the image.
  • HyperBand: Acquires information from multiple slices simultaneously to accelerate supported neurological examinations, including selected diffusion and functional MRI studies.
  • PROPELLER: Uses a specialized data acquisition technique to reduce the effects of patient motion during suitable examinations.
  • SONIC DL: Uses deep-learning acceleration for supported MRI acquisitions, including certain cardiac and three-dimensional imaging applications. Compatibility depends on the software generation, licensing, and available upgrade path.

These technologies can be incorporated into compatible Architect configurations, with installed functionality varying by software and hardware package.
