ScholarBank@NUS Repository. | Abstract: | We have developed a computer program for PIXE tomographic reconstruction of trace elemental distributions using the maximum-likelihood expectation-maximization (MLEM) algorithm. This algorithm is based on the exact stochastic model of X-ray yield measurements. Energy loss of the incident particles and attenuation of the X-ray photons are incorporated into the reconstruction algorithm so quantitatively accurate trace elemental concentrations can be obtained. The reconstruction algorithm has been tested using calculated X-ray yields generated from a micro-PIXE line scan simulation program. This algorithm is capable of reconstructing elemental distributions using only four angular views of the sample. © 1995. | Source Title: | Nuclear Inst. and Methods in Physics Research, B | URI: | http://scholarbank.nus.edu.sg/handle/10635/97552 | ISSN: | 0168583X |
