Abstract
Filtered backprojection (FBP) reconstruction is the method of choice for diagnostic xray CT, despite the fact that backprojection is computationally costly. FBP image quality is superior over fast Fourier reconstruction techniques because interpolation errors are localized and the backprojector applies the Radon transform, annihilating all measurement errors orthogonal to its range. We discuss computational complexity, sampling rates, and quadrature techniques for FBP reconstruction of thermo/photo/optoacoustic data.
