Nonnegative Gaussian process tomography for generalized segmented planar detectors

2 Dec 2019  ·  D. Blyth, N. Mullins, E. Galyaev, J. Holmes ·

The concept of Gaussian process tomography along with nonnegative constraints is applied in the context of high-resolution image reconstruction using segmented planar detectors with few readout channels. Expanding on the concept of 2-D strip-like projections, 3-D projections as well as more generalized detector segmentation and readout channel mappings are explored. A focus is placed on reconstructing dose distributions in proton therapy pencil beam scanning.
