My first thought is for you to run two times, once with starting angle 0 at 256x256, then a second time with starting angle 45 at the larger size.
But if you need other angles, that will be tedious, and I suggest to crop them programmatically using Octave or python.

Thank yo Greg!My question would also be for drr: for different -r option in command line -- resolution of output Xray image, the different resolution settings would only lead to different size of same body part Xray image right?

The drr options are terrible, by the way. I should make them easier to use.
The -r option is incorrectly documented in the help. It is the detector resolution in pixels, not in mm! You'll want to increase this by sqrt(2). But you'll need to round the result to get an integer.
You also need to set the -z option. Your detector size in mm should be scaled up the same way, rounding the result to get the same pixel size.
I think those are the only things you will need to change.
