GRICS: Reconstruction process of a magnetic resonance image disrupted by patient physiological movements

Presentation

Adaptive magnetic resonance imaging (MRI) allows to adapt the imaging process to patients, taking into account their physiology and movements. During medical images acquisition, movements induce a kinetic blur, which alter image quality and can make the diagnostic impossible. 

This new process remedies these problems by providing a way to reconstruct the image, by taking into account organs and patient movements  directly from corrupted experimental data. It is based on an iterative image optimization, using data obtained by motion sensors. This process enables a  reconstruction of the MRI image without motion blur.

Competitive advantages

• Better image quality and no data loss in comparison with blur correction technologies currently available.
  

Validation

• Several image acquisitions on moving patients with and without « GRICS » technology - images available-

Applications/Markets

• MRI, NMR, Tomography, Echography;
• Medical imaging;
• Cardiac, pulmonary, renal, hepatic imaging…
