Centroidal Voronoi Tessellation (CVT) space partitioning

A CVT is a special type of Voronoi tessellation when each generator, of each Voronoi cell, is located in the center of the mass of the cell.  CVT is an optimal partition corresponding to an optimal distribution of generators. A set is tessellated by k generators (is the position of the generator) into k Voronoi cells (denoting…

Catheter overloading for patient specific QA in brachytherapy

Patient specific QA is the gold standard for external beam radiotherapy (IMRT/VMAT). Brachytherapy treatment planning (BTP) has become more complex due to advanced imaging (MR, PET, US), advanced dose calculation algorithms and new applicators.
