Datasets:
Are the "scans" different series from the same study or from different studies?
Hi @ibrahimhamamci @sezginer ! I have a question re the dataset. The dataset card mentions the following:
Our folders are structured as split_patientID_scanID_reconstructionID. For instance, "valid_53_a_1" indicates that this is a CT volume from the validation set, scan "a" from patient 53, and reconstruction 1 of scan "a". This naming convention applies to all files.
For example, the screenshot below shows different scans for patient 968 (each scan has two reconstructions, sharp and soft tissue kernels). But, it is not clear if the word "scan" refers to a series from the same patient study (same visit), or a series from an entirely different study (e.g. follow-up visit). All scans in a patient study should ideally correspond to different series within the study (patient --> study --> series 1, series 2, series 3,..). Can the authors of this dataset please clarify this point? It is crucial when using and describing this dataset in publications. Thanks!
Great, thanks for letting me know! May I suggest that the dataset card be edited to reflect this information? Might make it easier for others to find if they have the same question as me. I also found that the train_metadata.csv and valid_metadata.csv files contain the StudyDatecolumn that confirms your description above.
