Private tags after anonymization about evil-dicom HOT 2 CLOSED

HiMany thanks, I thought it was something l had missed.Thank you for your time.James On Thursday, 1 February 2018, 23:04, Rex Cardan <[email protected]> wrote: It has nothing to do with anonymization. It has to do with the format used for writing the DICOM file to bytes. If you use EXPLICIT VR in your DICOM settings, it will write the VR. Otherwise, it just writes the tag, and on reading back, if the tag is not in the Evil DICOM dictionary, it won't know which kind of VR it is. Here is a test that shows you what I mean:` var dcm = new DICOMObject(); dcm.Add(new LongString(new Tag("32751000"), "Online3D")); var dcmBytes = new byte[0]; //Start empty using (var ms = new MemoryStream()) { using (var dw = new DICOMBinaryWriter(ms)) { //Explicity DICOMObjectWriter.Write(dw, DICOMIOSettings.DefaultExplicit(), dcm); } dcmBytes = ms.ToArray(); //Store to read back } var dcmBack = DICOMObject.Read(dcmBytes); //This passes Assert.IsTrue(dcmBack.FindFirst("32751000").VR == EvilDICOM.Core.Enums.VR.LongString); using (var ms = new MemoryStream()) { using (var dw = new DICOMBinaryWriter(ms)) { //Implicit DICOMObjectWriter.Write(dw, DICOMIOSettings.Default(), dcm); } dcmBytes = ms.ToArray(); //Store to read back } dcmBack = DICOMObject.Read(dcmBytes); //This fails Assert.IsTrue(dcmBack.FindFirst("32751000").VR == EvilDICOM.Core.Enums.VR.LongString);` — You are receiving this because you authored the thread.
