Save radius and phase information in FFT for radial PSD

Hi everyone

I have a, what seems to me, very simple problem. But during past two days of trying different things and googling, I cannot figure it out.

I have a microscopy image, with a know scale (nm/px). I to the FFT on a specific region and get the power spectrum below. Now, imagej already provides the radius, angle and value for every pixel, which I can even measure with the point selection tool. What I want, is to know the radius and value for every pixel, such that I can plot the intensity vs. the radius.
But gun to my head, I cannot figure out how to get that information. The profile only gives me one value at one radii, and i don’t want to manually select 512^2 pixel with the multi point tool.

Does anyone have an idea?

Thank you all in advance!
