    EXCELLENT explanation, and in perfectly understandable English. I've been a radiologist for 35 years, and you clearly know your stuff. I'm moving into the AI-imaging world; I look forward to more of your videos.

    I like it so much when people take care about reproducibility of their research especially when it comes to computational science. Code should be supplementary material along with the data, and there shouldn't be "unnecessary hurdles on a way to reproducibility" (a citation from a Nature article as I recall). We have a technology for this like online repositories and code should also get doi numbers.
    Thanks for this video!

    Hi, my jaw dropped on thie masterpiece, but I have one question:
    In the import file, you used a CT_scan.npy, wich means, and correct me if I'm wrong, that you transformed 200 layers of 1 exam that was .dcm in one single archive that is a group of arays .npy.
    Do you have any tutorial on how to do that or some link to how can I learn the way you did it? It would help a lot! Thanks!

  • @domillima

    Excellent video. In my case, I have CT DICOM files that I’ve segmented using 3D slicer. I read those files in with sitk and need to work on processing them with labels the way you did here so that I can multiple the image x the labels and remove background nose before training into my model. Would love more videos along this line!

    Great video! I wonder how do you include more complex organs with lobes. For example, if you want to keep the trachea. I see that the lungs are kinda cut short on the bottom end because of the 3 biggest areas threshold. Would be cool to follow the diggestive system by using the center of mass function (at each layer, the center can shift a small amount).

    Interesting video, Thanks.
    There are many heuristics and parameters used in the video which may not work in the general case. So, I was wondering if you choose to look at slices that use the first 2 dimensions instead of the last 2 dimensions (different slices should be at different depths of the chest-back dimension), it might be easier to find out the location of the lungs and get rid of the table (the table should be less or more always at the same depth)?
    In any case, it must be assumed that this type of problem is more suitable for three-dimensional segmentation than the union of two-dimensional segmentations.
    Regardless, I would be very happy if you made a tutorial to image-processing libraries (2D) in the same style as you did for NumPy, SciPy & SymPy

The challenge I have is that the code you used for finding boundaries and areas is not working properly due to having thin layers side by side. Do you have any suggestions as to how to fix this issue?
