2.0 INTRODUCTION
This is the newest public version of blOCh, a MATLAB library for computing and simulating RF pulses using various optimization methods from optimal control theory and by means of the Bloch equations. It extends to three spatial dimensions and a spectral dimension too. Hence, it can optimize RF pulses for a target defined in 4D.
blOCh includes four main script files (blOCh__spc, blOCh__khr, blOCh__opt, and blOCh__sim) that can do the basics. And there is a package folder with supplementary scripts for advanced stuff. The four main scripts involve spatial dependencies, temporal dependencies, optimization parameteres, and simulation facilities, respectively. And each of them can be replaced by alternative functions.
It is also possible to add more functionality to blOCh, e.g., by including frameworks from other researchers through the packages folder. I would need to consider a request and I would need the corresponding authors acceptance of including the framework in blOCh.
As many opensource softwares, blOCh does not yet come with a manual and as in an ideal world I should make one. Until then you are welcome to contact me for help and collaborations, and I will setup blOCh for your specific need if I can.
Best wishes
