E. Rokita et al., THE USE OF THE MAXIMUM-ENTROPY METHOD FOR THE IMPROVEMENT OF THE SPATIAL-RESOLUTION OF THE MICRO-PIXE MAPS, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 130(1-4), 1997, pp. 138-143
The deconvolution procedure based on the maximum-entropy method is app
lied to improve both resolution and noise characteristics of micro-PIX
E maps. The procedure is simple to execute, fast, easily automated and
assumes no a priori information. The best improvement is observed for
data with low statistics. Special emphasis is,given to the difficulti
es and limitations of processing micro-PIXE data. Examples of applicat
ions for biomedical samples are presented.
