Abstract
A method for rapid limited-angle tomography is suggested thatallows the reconstruction of density distribution in hardwood sampleswith high accuracy and spatial resolution from only a few x-rayprojections. The sparsity of the experimental x-ray data iscompensated by incorporation of a priori knowledge aboutgeneric wood macrostructure, as well as some morphological informationobtainable from optical images of the sample surface, in themathematical framework of the tomographic analysis. Numerical testsof the proposed method confirm its potential as a practical techniquefor nondestructive testing of trees for scientific and industrialpurposes. It can also be useful for the analysis of other types ofobject with an underlying layered structure.
