The HAADF (high-angle annular dark-field) STEM imaging has widely been applied in tilt electron tomography because it shows Z-contrast. However, in this technique, we still need to suppress the unwanted diffraction contrast.

However, for very thick specimens or those with high mass density, HAADF STEM imaging is no longer applicable to tomography study as the signal decreases with increase of the specimen thickness because more scattering proportionately occurs outside the outer edge of the annular detector.
