3D datasets used in Toward-ground-truth optical coherence tomography. Guangming Ni et al., "Toward ground-truth optical coherence tomography via three-dimensional unsupervised deep learning processing and data", 2023 There are two dataset: OCT-R1 and OCT-R2. OCT-R1 contains three-dimensional (3D) data collected from 41 human eyes using a BM-400K BMizar (Topi Ltd.) OCT scanner at Sichuan Provincial People's Hospital. To enhance the diversity of the data, we performed scans over two different ranges.
