i downloaded Data from TCIA and its already have a seg results.
what i want to do is exporting the segmented lesion out of the whole volume as dicom file to start working on it.
what i’m getting after exporting the file is the segmented area without any data only empty contour.
What work would you like to do on it?
I’m what software?
What DICOM information objects that software can read - CT, Segmentation, RT structure set,…?
i want to use it for ML for extracting the features of each voxel to make it able to differentiate tumors
i’m runinng python script on juypter.
DICOM is great as an archival and data exchange file format, but not as a working file format. To train an AI model you would normally convert input images from DICOM to NRRD or other research file formats that are simpler and more efficient than DICOM.
You don’t need to deal with DICOM until the very end of your project, when you deploy your tool to hospitals for clinical use. If you deploy your model using an application framework (such as 3D Slicer) then you don’t need to think about DICOM even then, aS the framework takes care of DICOM import/export.
that’s great to know thank you for saving my time.
but
the issue remain that when i export nrrd i dont get info about the real lesion its just empty photos
the pixels are 0 1
Usually you use the original images and segmentations (that you call “empty photos” that contain discrete label values) as training data for your network.
