A visual comparison suggests that the image quality becomes acceptable for P ≥ 192, see the second column in the Figure 8.9. 8.3 Electron microscopy/tomography Electron microscopy/tomography (EM) =-=[130]-=- is an imaging technology based on the similar principle as X-ray CT but uses electron flux to probe nanoscale objects. It is widely used in biology and material science and can provide a few tenth na...
