EIT dataset with MAX30009 and ADG706

This is a time difference dataset from EIT, consisting of 200,000 simulation data points built using EIDORS and 79 data points collected by ourselves. The acquisition devices used were MAX30009 and ADG706, with a constant current source excitation of 49.984 kHz 1.28 mA (RMS) and 16 electrodes. The `base` folder contains our basic experiments, including simulation and test datasets of blocks, triangles, and squares, labels, training files, and test files; the `transfer` folder contains the training set, validation set, training scripts, test results on simulation and test datasets, and comparison results with other methods; the `pretrained_checkpoint.pth` file contains pre-trained weights that can be directly used for transfer learning or testing.
