DICOM and non-DICOM format files

Altris AI works with any OCT macular examination in DICOM and non-DICOM formats (images) like jpg, png, bmp, and tiff.

Altris AI recommends using the DICOM file format because it contains the original image pixel data without any modifications to the study metadata.

Therefore using the DICOM type of file gives you more opportunities within the platform:
Such features as retina layers thickness in a Single scan tab, linear measurements, area, and volume calculations from the Measurements tab are only available when using DICOM file format (not images). In case you upload an image, retina layers thickness won't be available, as well as the measurements.
Another advantage of the DICOM format is that you can add patient and examination details in a few clicks by just uploading a DICOM file since this information is being pulled out automatically. In the case of the Images, when for example uploading an examination, you would have to fill in manually a bunch of information such as scan widths, eye type, etc.
Taking into consideration all mentioned above, usage of DICOM format files saves time, increases efficiency, and gives you more opportunities within the Altris AI platform.


The recommended settings for data export in Dicom format:

  • Retina 3D, horizontal b-scans (no fundus image should be exported with b-scans)
  • Retinal area of interest – 6-7-8 mm (no wide scans!)
  • Scan Width - 1024
  • Scan Height - 944
  • Altris AI analyses the central sector of the retina and does not provide optic nerve analysis
