    DICOM: Работа с DICOM файлами.
    В этом разделе
    Цифровая обработка изображений и коммуникации в медицине (DICOM) - это стандарт для передачи и управления информацией о медицинских изображениях и связанных с ними данными. Стандарт DICOM включает определение формата файла и протокол сетевой связи.

    VintaSoft DICOM .NET Plug-in имеет набор классов, которые позволяют очень легко получать изображения и данные пациентов из DICOM файлов.

    Класс DicomSeriesManager

    Класс DicomSeriesManager позволяет группировать файлы/изображения DICOM по DICOM-сериям.

    Вот C#/VB.NET код, демонстрирующий, как распечатать информацию о DICOM-серии для указанных DICOM-файлов:
    /// <summary>
    /// Prints information about DICOM series to the console.
    /// </summary>
    /// <param name="dir">The directory path.</param>
    public static void PrintDicomSeriesInformation(string dir)
    {
        // create the DICOM series manager
        Vintasoft.Imaging.Metadata.DicomSeriesManager manager = new Vintasoft.Imaging.Metadata.DicomSeriesManager();
        manager.Images = new Vintasoft.Imaging.ImageCollection();
    
        // get names of DICOM files in file directory
        string[] dicomFilePaths = System.IO.Directory.GetFiles(dir, "*.dcm", System.IO.SearchOption.AllDirectories);
        // add DICOM files to the DICOM series manager
        foreach (string dicomFilePath in dicomFilePaths)
            manager.Images.Add(dicomFilePath);
    
    
        // get patient identifiers from DICOM files
        System.Collections.Generic.IList<string> patientIdentifiers = manager.GetPatientIdentifiers();
        // for each patient identifier
        foreach (string patientIdentifier in patientIdentifiers)
