T2 Relaxometry with Indirect Echo Compensation from Highly Undersampled Data
This invention enables accurate T2 estimation from highly undersampled data with indirect echo contamination. The technique is based on an iterative algorithm where the signalmodel (which is derived from a model that takes into account the presence of indirect echoes) is linearized using principal component analysis. The goal of the proposed SlicE Resolved...
