Efficient reconstruction of 3D images from photon starved integral imaging using PMLEM Conference Paper uri icon

abstract

  • Reconstruction of three dimensional (3D) images from photon counting integral images was recently demonstrated by applying several methods including: maximum likelihood estimation, Bayesian estimation, and statistical estimation involving truncated Poisson statistics. Here we present simulation results for a new estimation approach implementing Penalized Maximum Likelihood Expectation Maximization (PMLEM) that better incorporates prior information in the reconstruction process.
