The Relaxation-Corrected Navigator and Gating Technique: An Improved Correction Methodology for Eliminating Both Motion Artifacts and Spin-Condition Artifacts in Thoracic and Abdominal Imaging
- 详细技术说明
- This patented technology provides a system for recording magnetic resonance images with reduced relaxation-related artifacts. This improves upon conventional methods for acquiring MRI images of in vivo tissue by augmenting the procedures for eliminating artifacts caused by motion and the spin of the magnetic resonance-active nuclei. Specifically, to eliminate such spin the delay time is defined by N*T1, where N is a numerical value greater than or equal to 5 and T1 is the characteristic time constant for decay of spins back to the equilibrium longitudinal state.
