Joint T1 and T2 Mapping with Tiny Dictionaries and Subspace-Constrained Reconstruction
[article]
2018
arXiv
pre-print
Preserved Fulltext
Based on simulation results, tiny dictionaries were used for T1-T2 mapping in phantom and in vivo studies. Reconstruction and parameter mapping were performed entirely in subspace. ...
Purpose: To develop a method that adaptively generates tiny dictionaries for joint T1-T2 mapping. ...
The demonstrated ability to perform reconstruction and parameter mapping entirely in subspace justifies the coined term "tiny dictionaries". ...
