  I am looking for a backprojector subroutine, preferably with the following
characteristics:

	- source in fortran (or translatable from C)

	- for use with parallel-beam, filtered backprojection image
		reconstruction

    ** 	- code should vectorize and/or parallelize

(optional, don't really need, but would be nice to have anyway):

	- allow for center of rotation correction
	- allow for x or y shifting of the center of reconstructed image
	- allow for rotation of the reconstruction 	

  I'm not too thrilled with the Donner implementation(s), and what I have now
is just too spaghetti-ish to vectorize.  Does anyone have any good
references for something similar to the above description?  Please email or
post.  Thanks.
