Abstract

Transmission electron microtomography (TEMT) is a powerful technique to investigate the three-dimensional structures in nanometer scale, which is based on the transmission electron microscopy (TEM) and computerized tomography (CT). In this study, we demonstrate the advantage of zero-loss imaging based on electron energy loss spectroscopy (EELS) in the quantitative data acquisition for TEMT. Transmission of zero-loss image during tilting the specimen agreed with the calculated transmission under assumption of the increase of effective specimen thickness, which is necessity to obtain the quantitative reconstructions according to the principle of CT. On the other hand, the transmission of unfiltered images was almost constant during tilting. It is concluded that the zero-loss imaging is always required for TEMT.
