Dataset

Dear Organizers,

Could you tell me how the dataset was prepared? For example, are the noisy images artificially degraded versions of the clean images? Also, do images with the same identifier (e.g., patient-1-4C-frame-1) in the clean and noisy sets correspond to the same patient, the same cross-sectional view, and the same cardiac phase? I’d like to confirm this, as the images with the same identifier seem to have slightly different morphologies.

Thank you for your inquiry. To clarify, both the noisy and clean images in the dataset are sourced from real data and are not artificially generated or paired. Images sharing the same identifier in both sets do not necessarily correspond to the same subject, anatomical view, or cardiac phase.
