Hey Luis,

>From the deafening silence to your question, I'd say no.  I had a quick
look around CPAN and I see nothing for Radon in PDL or Perl in general.

Then I had a look at what a Radon Transform
<https://en.wikipedia.org/wiki/Radon_transform> actually is and it is
**well cool**!   We were talking last week about the episode of House with
the bullet fragments and the MRI machine and started asking, how _do_ you
get a 3D image from a bunch of attenuations?

As it's not far off the Fourier transform, I'd say it's possible and maybe
PDL::Transform's map <https://metacpan.org/pod/PDL::Transform#map1> function
with it's { map => 'fft' } option is a place to start hacking.  I'll have
some free time in a couple of months if you want a willing novice-to-PDL
collaborator.  It sounds like something that Perl should have in it's
toolbox if we want our language to be serious about Scientific Perl.  I
think I've got a "tuit" around here somewhere.  :)

Saludos,
Boyd
