Fourier-based Inversion of Partial X-ray Transforms in n Dimensions
Murdock G. Grewar
We present two theorems describing analytic left-inverses of partial X-ray transforms. The first theorem concerns X-ray data collected with an arbitrary distribution of parallel pr…

Practical Global Backprojection-Convolution in Transmission Cone-beam Computed Tomography
Murdock Grewar, Glenn Myers, Andrew Kingston
Global backprojection-convolution (GBC) is a recently developed theory for exact reconstruction in transmission cone-beam computed tomography (CBCT). It is the first exact inversio…
