Medi_Gui error on attempting to load Phillips data

[Paul Mullins]

Dear MEDI_TOOLBOX developers,

I am trying to load some Philips data and use the MEDI_GUI. IN doing so I browse to the dicom directory. When I click the load button I get these error messages:

Warning: File and dictionary VR values do not match for attribute "RespiratoryIntervalTime" (0020,9254). Expected: FD. Found: UN. Consider setting the

'UseDictionaryVR' parameter to true.

Error while evaluating UIControl Callback.

Any ideas of what may be causing these problems?

Okay, managed to solve this - I think - by editing the MEDI_GUI.m file, line 164 from:

 

[iField,voxel_size,matrix_size,CF,delta_TE,TE,B0_dir] = Read_DICOM(FilePath);

to 

[iField,voxel_size,matrix_size,CF,delta_TE,TE,B0_dir] = Read_Philips_DICOM(FilePath);

I am sending this solution and reply, so that if some one else has a similar problem in the future they can find this solution to it.

One more thing I have worked out - to remove the annoying warning messages about 'UseDictionaryVR' you may need to further modify the Read_Philips_Dicom.m file by inserting 'UseDictionaryVR', true into lines 39, 52, and 75 like so:

39 -  info = dicominfo(fnTemp, 'UseDictionaryVR', true);

52 -  info = dicominfo([DicomFolder '/' filelist(i).name], 'UseDictionaryVR', true);

75 -  info = dicominfo([DicomFolder '/' filelist(i).name],'UseDictionaryVR', true);
