Introduction #
The Large Dataset of Labeled Optical Coherence Tomography (OCT) and Chest X-Ray Images encountered challenges related to reliability and interpretability in implementing clinical-decision support algorithms for medical imaging. They embarked on developing a diagnostic tool utilizing a deep-learning framework specifically designed for screening patients with common treatable blinding retinal diseases. The final OCT dataset contains 109,309 images.
The full dataset consists of the following parts:
- ZhangLabData: OCT (current)
- ZhangLabData: Chest X-Ray (available on DatasetNinja)
Spectral-Domain OCT Imaging
The primary application was in the diagnosis of retinal OCT images. Spectral-domain OCT captures high-resolution optical cross sections of the retina, assembling them into three-dimensional-volume images. It has become a widely performed medical imaging procedure, particularly in diagnosing age-related macular degeneration (DRUSEN, choroidal neovascularization CNV) and diabetic macular edema (DME).
OCT imaging has become a standard of care in guiding the diagnosis and treatment of leading causes of blindness, including AMD and diabetic macular edema. The prevalence of these diseases is significant, with millions affected, and the utilization of anti-vascular endothelial growth factor (anti-VEGF) medications has revolutionized treatment.
Dataset Details and Training Outcome
The authors obtained 207,130 OCT images initially, with 108,312 images passing quality review for training the AI system. Testing involved 1,000 images from 633 patients. After 100 epochs, training was halted due to the absence of further improvement in both accuracy and cross-entropy loss.
An independent test set of 1,000 images was used to compare the AI networkās referral decisions with those of human experts. The AI systemās performance was comparable to human experts in distinguishing patients needing urgent referral.
The authors conducted an occlusion test on 491 images to identify areas contributing most to the neural networkās assignment of the predicted diagnosis. The testing successfully identified regions of interest, demonstrating high accuracy in recognizing clinically significant areas of pathology.
Summary #
Large Dataset of Labeled Optical Coherence Tomography (OCT) and Chest X-Ray Images is a dataset for a classification task. It is used in the medical industry.
The dataset consists of 109309 images with 0 labeled objects. There are 2 splits in the dataset: train (108309 images) and test (1000 images). Alternatively, the dataset could be split into 4 classification splits: NORMAL (51390 images), CNV (37455 images), DME (11598 images), and DRUSEN (8866 images). The dataset was released in 2018 by the Zhang Lab, Univercity of San Diego, USA.
Here are the visualized examples for the classes:
