Abstract

A method for fully automatic modelling of medical structures with homogeneous attenuation function from few projections is provided. The object of interest is modelled as a polyhedron with triangular surface mesh. The optimization of both the coordinates of the polyhedral model and the attenuation value of the polyhedral model is performed during a data reconstruction. This results in an attenuation value together with a three-dimensional surface model of the physical structure imaged. Combining several polyhedral models into one compound model, the method may allow for fully automatic modelling of medical structures with piecewise constant attenuation function.
