The results for my pictures were not good so i decided to put a black threeshlod under which all pixels are black and a white threeshol above which all pixels are white.

Do you have any idea how i could automize and speedup the process? Or simply a good idea? You can use remap function from opencv: See this example :.

I am trying to resize DICOM images of different dimensions into a common dimension size for training my neural network. I thought that cv2 could solve my problem. But I am getting a 'datatype not understood error' in my jupyter notebook. I am trying to create a tensorflow neural network that could predict the class of the image.

Thus, I need images of a common dimension size for the first layer training. You will have to convert all of your images into a suitable format e. Then again you may want to use a different library for re-sizing as well, it is probably not worth the effort to:.

I'd recommend you instead look into a library or tool specifically designed to work with DICOM images. Learn more. Asked 1 year ago. Active 12 months ago. Viewed 1k times.

That gives you very powerful true 3d handling and is fast it's wrapped around complied C. However, because it's a lot more powerful than pydicom, it also has a much steeper learning curve - but does have many examples and online jupyter notebook tutorials.

However, if you only really want basic 2d image-at-a-time type processing, pydicom is the way to go. Learn more. Asked 8 months ago. Active 7 months ago. Viewed 72 times.

As clinical radiologists, we expect post-processing, even taking them for granted. We will extract voxel data from DICOM into numpy arrays, and then perform some low-level operations to normalize and resample the data, made possible using information in the DICOM headers.

The remainder of the Quest is dedicated to visualizing the data in 1D by histogram2D, and 3D. Finally, we will create segmentation masks that remove all voxel except for the lungs.

Python has all the tools, from pre-packaged imaging process packages handling gigabytes of data at once to byte-level operations on a single voxel. The Kaggle data science bowl dataset is no longer available. Thanks for the tutorial, I have been looking at the images, and I think I understand most of the preprocessing.

However, after the resampling taking into account we have different pixel spacing and slice thicknesswe obtain volumes of different dimensions for each patient. How would you recommend resizing in order to get for all patients a volume of dimensions XxYxZ, with spacing of 1x1x1? For me this makes more sense to be able to compare them. Thanks in advance. It turns out it is a natural side effect: resampling isotropically means so all voxels are the same size but each exam will be different sizes this is a common approach because patients are different sizes.

This is because CT scans are commonly obtained at a constant x matrix. This means that each CT scan actually represents different dimensions in real life even though they are all x x Z slices. Think of each examination as having a fixed millimeter-per-voxel conversion factor which is based on patient size and different from exam to exam. IIf we made all the XxYxZ the same for all exams, then the voxel size can no longer be 1 x 1 x 1 mm, and vice versa.

Thanks for your fast response, is much clear now what is happening.

My aim is to be able to feed a 3d Neural network with the volumes, and this requires that all of them have the same shape. I understand the trade off you mention in the last paragraph, however, is there a transformation you could suggest to be able to get the images in the shape we want? This should force all the resampled data to be in the same dimensions. Thank you for this tutorial. I try to do your segmentation tutorial.

But I have some problem of your tutorials. Erosion and and dilation process is ok. Then color labels process also is ok. Thank you. Then because boxes that represent lungs are more likely to be shaped a certain way than boxes that represent other labels, you can perform the mathematic to determine which label is most likely the lung.

Try this reference to understand how bbox works. The precise numbers are determined empirically, so to get the right masks you may have to try different numbers.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.
