Introduction: Politics and Health,ame molecular assemblies after isolation. As with studies using single-particle cryoelectron microscopy, specimens smaller than 1 µ in size can be prepared for cryoelectron tomography by plunge-freezing (.). Cells or organelles can be rapidly frozen directly on an electron microscope grid in thin la

In this chapter, we enquire whether it is valid in electron microscopy, where intuition might well lead us to suspect that it is not. Electron-specimen interactions are very different from those encountered in X-

Both convolution back-projection and weighted back-projection algorithms are based on the same theory as Fourier reconstruction methods, whereas iterative methods normally do not take into account the Fourier relationships
