Abstract :
A statistical method for computing 3-D reconstructions of virus particles from cryo electron microscope images and minimal prior information - particle symmetry and radii - is described. Two different approaches for parallel implementation of the algorithm are described based on parallel processing of different images and based on parallel numerical integration and numerical results showing nearly linear speedup are presented.
