This dicom file contains 2 4D images one of type [ORIGINAL\PRIMARY\M_FFE\M\FFE] an the other of type [ORIGINAL\PRIMARY\VELOCITY MAP\P\PCA]. I'm trying to use ImageFileReader + GDCMImageIO but as a result only a big 3D volume is obtained.</div><div><br></div><div>Attached is a file containing the output of the tags contained inside the DICOM.</div><div><br></div><div>One difficulty I have found is that the volumes have different rescale parameters, <br></div><div><br></div><div>* frame of type ORIGINAL\PRIMARY\M_FFE\M\FFE has:</div><div><br></div><div>

For the example attached, we have 25 time steps and this means that the first 25 slices in the pixel data correspond to the first slice of each 2 3D volumen. Is it possible to read this kind of data using ITK? If not any recommendation of how to read to create ITK images from it?</div><div><br></div><div>Thanks in advance and best regards,<br></div></div></div></div><meta http-equiv="x-dns-prefetch-control" content="on"><br><br> </div> </div> </div></body></html>
