标 题: Asymmetric angle Parallel Beam in CT image reconstruction
发信站: BBS 未名空间站 (Wed Dec 13 12:59:43 2006)
if i use algebraic method, should I treat asymmetric just like symmetric,
updates all cells falling in the ray, just use different way of defining
each projection for angles?
Thanks. | c*******l

the way algebraic method works is that it projects in the n degree space.
evenly angles work. but i dont know if that theory doesnot limit to even
angles or not :(
thanks for help
