I assume there already was a DICOMDIR created with some other application that included the Icon? then the foreach crashes when you reach the newly added entry.

I don't know why the line of code worked well before you stored the file with fo-dicom. DicomDir allows to contain a small icon to show if you want to display some previews quickly.Īctually imageRecord should contain all the informations you might need like instanceuid or filename etc. One of those optional informations, that fo-dicom does not automatically add, is the Icon. When Adding an image to the dicomdir it is up to you to add additional information. DicomDir does only contain some main data of the image. You try to access the IconImageSequence (0088,0200) that is obviously not present. I don't know if I'm missing something regarding saving a DICOMDir file, or if it's an error. Var dicomDataset = imageRecord.GetSequence(DicomTag.IconImageSequence).Items.First() //This line works fine before saving the image in the method above, but throws when opening the same study Var dicomdir = DicomDirectory.Open(dicomdirPath) ĭicomdir.AddFile(dicomfile, //this executes without problems and the DICOMDIR is savedĪnd this is the series opening method: var dicomDirectory = await DicomDirectory.OpenAsync(dicomdirPath) įoreach (var patientRecord in dicomDirectory.RootDirectoryRecordCollection)įoreach (var studyRecord in patientRecord.LowerLevelDirectoryRecordCollection)įoreach (var seriesRecord in studyRecord.LowerLevelDirectoryRecordCollection)įoreach (var imageRecord in seriesRecord.LowerLevelDirectoryRecordCollection) Var dicomdirPath = Path.Combine(studyPath, Constants.DICOMDIRFileName) Var pathImage = Path.Combine(dirImages.FullName, imageFileName) ĭicomfile.Save(pathImage) //Image is saved fine and it's well formed, I've checked opening it with an online DICOM viewer Var pixelData = DicomPixelData.Create(dataset, true) This.FillDataset(dataset) //this function copies several Tag values of an already existing DICOM Series file, such as Patient informationĭataset.Add(DicomTag.PhotometricInterpretation, ) ĭataset.Add(DicomTag.Rows, (ushort)rows) ĭataset.Add(DicomTag.Columns, (ushort)columns)

Then, I tried adding that file to the DICOMDIR, so that the Dir references the new file, and, though the saving is successful, when I try to open the DICOMDir and its series again, I get a 'Tag: (0088,0200) not found in dataset' exception.Ĭode is as follows: var dataset = new DicomDataset()

Based on this example I've successfully created and saved to disk an image from a series. I'm experiencing an issue with adding a file to a DICOMDir.

Since the dicomdir file is invalid
