Blob basis functions yield promising results in multiple imaging modalities and we seek to test their use in proton CT (pCT). Unlike the straight-line approximations in
x-ray CT, in pCT discrete steps along a most likely path formalism of the nonlinear paths of Coulomb-scattered protons is used. Below is an illustration of the basis
functions of interest. Voxels have a uniform value inside a set domain while blobs are spherically symmetric and taper smoothly to zero at their border.
