Our Technology(Magnetic Resonance Imaging) GE SIGNA 1.5T Excite High Definition

General Electric SIGNA 1.5T Excite High Definition

With new, high-density, multi-channel coil technologies, a faster and fully scalable reconstruction engine, and new parallel imaging acquisition and reconstruction technology, the Singa HDx 1.5T represents the next level of performance in 1.5T imaging.

Features

• 1.5T Magnet
  The 1.5T Magnet guarantees high homogeneity and provides excellent results in:
  • Large FOV imaging up to 48cm X 48cm X48cm
  • Off-centre FOV imaging such as knee, shoulder and wrist imaging
  • Fat saturation techniques required for abdominal, breast, musculoskeletal imaging
  • Demanding applications such as cardiac, fMRI, diffusion tensor and spectroscopy
  
  
• TwinSpeed Gradient System
  Singa HDx 1.5T gradients are of high fidelity and performance, delivering the necessary accuracy and reproducibility for top quality results across all applications and all pulse sequences. It is especially advantageous in acquisitions demanding high spatial and temporal resolution and in rigorous applications such as Echoplanar (EPI) and Diffusion (DT) imaging. The System combines high gradient amplitudes and slew rates with 100% duty cycles, assuring optimized contrast, SNR and scan time for any exam.
  
  The gradients are also non-resonant and shielded to minimise eddy current and improve image quality. The gradient and RF body coils are integrated into a single, water cooled unit to maximise performance.
  
  
• TwinSpeed Design
  By utilizing two concentric sets of non-resonant gradient coils, the TwinSpeed gradient coil option provides maximum performance with compromising the imaging FOV. Its Zoom mode offers simultaneous high gradient amplitude (50mT/m) and slew rate (150T/m/s) while avoiding peripheral nerve stimulation and maintaining a 60 cm bore aperture.
  
  In addition to the standard linear shims, the Signa HDx 1.5T with TwinSpeed provides an advanced compensation technique called High Order shim. It automatically compensates for magnetic field distortions originating in the individual patient, thus resulting in improved homogeneity, especially in spectroscopy and ultra-fast imaging techniques.
  
  
• Meticulous Computer Architecture
  Its computer architecture minimises the delays associated with conventional MRI, Built on a parallel, multiprocessor design, it enables simultaneous scanning, reconstruction, filming, archiving, networking and post-processing—ideal for both clinical and research environments.
