(a) Original image and simulated sensitivity map, (b) comparison of pseudo-inverse and Bloch-LSQR solved B 1 -RRFC image reconstruction results, and (c) the corresponding deviation maps from original image (in |%|).

Journal: Computational and Mathematical Methods in Medicine

Article Title: Model for B 1 Imaging in MRI Using the Rotating RF Field

doi: 10.1155/2014/461647

Figure Lengend Snippet: (a) Original image and simulated sensitivity map, (b) comparison of pseudo-inverse and Bloch-LSQR solved B 1 -RRFC image reconstruction results, and (c) the corresponding deviation maps from original image (in |%|).

Article Snippet: Instead of applying ( ) and the linear map equation , the nonlinear Bloch-LSQR solution was modeled by populating the matrix E whilst calling the Bloch function written in Matlab script, followed by the solution of ( ) by using the lsqr method in Matlab.

Techniques: Comparison

3D- B 1 -RRFC encoded results using Bloch-LSQR solver: (a) original 3D image, (b) normalized sinc (line) and sech (dotted line) RF pulses (absolute magnetic flux density in μ T over time), (c) 3D- B 1 -RRFC using sinc , and (d) 3D- B 1 -RRFC using sech RF pulse.

Techniques:

Performance evaluation of the pseudo-inverse and Bloch-LSQR method versus the strength of encoding B 1 + -gradient. The encoding system performs best (<5%) when the unit B 1 -gradient is at least 10 −9 T/m.
