Fast Improvement of TEM Images with Low-Dose Electrons by Deep Learning

This is a dataset of High-Dose-Electron (HDE) images and Low-Dose-Electron (LDE) images taken with a transmission electron microscopy used in  H. Katsuno, Y. Kimura, T. Yamazaki and I Takigawa, Microsc. Microanal. 28 (2022), pp 138--144 (arXiv:2106.01718).

There are two LDE images for each HDE image.

cf) HDE image is 0001.tif and corresponding LDE images are 0002.tif and 0003.tif.

Equipment of TEM:

field-emission gun (JEM-2100F, JEOL, Tokyo)

OneView IS (Gatan, Inc., Pleasanton, CA, USA)

Typical magnification was 25,000x and 30,000x.

HDE image

The resolution was 4096 x 4096 pixels and its exposure time was 5 s.

The typical total doses was 1010 e-.

LDE image

The resolution was 512 x 512 pixels and its exposure time was 3.3 ms.

The typical total doses was 106 e-.
