Hello,

I want to convert dicom series (89 slices) into single file of 3D image using 3D slicer. Could you please help me by providing steps to do it?

I want to use this 3D image for segmentation purpose in ITK.

Hi - I guess you mean just save a nifti file of your dicom? Generally that’s just a matter [of loading the data and saving in a new format](https://www.slicer.org/wiki/Documentation/4.10/Training#Slicer4_3D_Visualization_of_DICOM_images_for_Radiology_Applications). Or if you want a more direct path you might use [dcm2niix](https://github.com/rordenlab/dcm2niix).
