Oh, I'd say it's a lot easier than that. The THETA keyword to RADON allows
you to specify the values of the angles in your sinogram, in radians. It
works nicely if you stick to the instructions (RADON is a bit picky about
whether parameters are given as named variables or not), and for any
angular range, not only 0-180 degrees.

Have fun
