faster cal_density_compensation_function?

[wenqihuang]

Hi @mmuckley,

thank you for the great job for non-Cartesian MR reconstruction!

I'm currently working on cardiac MRI with radial acquisition. I found that the computation of density compensation takes much longer time than the nufft itself. Would it be possible to speed it up? Or any suggestions on that?

Thanks in advance!

Hello @wenqihuang, you can reduce the number of iterations. 10 is definitely erring on the side of accuracy and is probably too many.

Thanks @mmuckley, it's faster now.
