SS-OCT Data

The central wavelength, spectral bandwidth and A-scan rate of the custom-made SS-OCT are 1064 nm, 100 nm, and 100 kHz, respectively.

The participants included people with DME or “1” (73 subjects), Healthy or “0” (54 subjects), and Non-diabetic patients or “2” (64 subjects) with AMD, CNV, or Macular Hole (MH) disorders. Each subject contains 300 B-scans with 300 to 1200 x 300 pixels resolution. These 191 are available in “1-Raw Dataset”.

Since some of the data have poor quality or the macular region was not captured, Quality Assessor (QA) was designed to automatically determine if the B-scan is suitable for further analyses or not. For the data preparation step, the manual quality assessment was performed on 191 volumes. The data was divided into two categories: 190 folders of qualified B-scans and 188 folders of non-qualified B-scans. Each folder consists of 1 to 300 B-scans. And all B-scans in each folder belong to one specific subject. The training data for QA is available in “0-QA-data”. Deep Convolutional Neural Network 1 method is employed to train QA. In the next step, QA was used to assess the quality of subjects in “1-Raw Dataset”. Volumes with more than 30 qualified B-scans passed.

0-QA-data: This data includes 190 folders of qualified B-scans and 188 folders of non-qualified B-scans. Each folder consists of 1 to 300 B-scans with 300 x 300 pixels resolution.

1-Raw Dataset: This dataset includes all 191 volumes before any processing. Each volume contains 300 B-scans with 300 to 1200 x 300 pixels resolution. The participants included people with DME or “1” (73 subjects), Healthy or “0” (54 subjects), and Non-diabetic patients or “2” (64 subjects) with AMD, CNV, or Macular Hole (MH) disorders.

2-Raw Dataset QA: Includes 124 volumes which has been obtained after image quality assessment with automatic cropping. Each subject contains 30 to 300 B-scan with 300 x 300 pixels resolution. The participants included people with DME or “1” (40 subjects), Healthy or “0” (50 subjects), and Non-diabetic patients or “2” (34 subjects) with AMD, CNV, or Macular Hole (MH) disorders.
