Abstract: There have been several advances to enable an SI definition for the Hounsfield unit, used in medical imaging, from a recent BTF program. These include the intrinsic dimensionality of the space of images available to x-rays under different tube voltages and how to lower the computational burden of scatter corrections. A rapid algorithm for determining optical scattering parameters, a warm-up problem for tomography, will be presented. Finally, there will be a look ahead at on-going work in diffraction-based microtomography.
