Zrozumienie zawartości pliku DICOM jest niezbędne dla rozwoju obrazu medycznego, rozwiązywania problemów i zapewnienia jakości.Tutorial ten pokazuje, jak zbudować kompleksowy widz metadanych DIKOM w C#, który ekstraktuje i wyświetla informacje o pacjencie, szczegóły studiów oraz parametry obrazy technicznej.

Co to jest DICOM Metadata?

Pliki DICOM zawierają dwa główne elementy: dane piksela (prawdziwy obraz) i metadane (informacje o obrazie).

  • ** Demografia pacjenta**: nazwa, identyfikator, data urodzenia, płeć
  • Informacje o badaniu: Data, godzina, opis, odniesienie do lekarza
  • ** Szczegóły serii**: Modalność, część ciała, protokół obrazu
  • Parametry obrazu: wymiary, przestrzeń piksela, ustawienia okna/poziomów
  • Informacje o sprzęcie: producent, model, wersja oprogramowania

Przeglądarka metadanych pomaga deweloperom sprawdzić te atrybuty do debugowania, weryfikacji i analizy danych.

Podstawowe metody ekstrakcji

Zacznij od ekstrakcji powszechnych atrybutów DICOM:

using Aspose.Medical.Dicom;

public class DicomMetadataViewer
{
    public DicomMetadata ExtractMetadata(string filePath)
    {
        DicomFile dicomFile = DicomFile.Open(filePath);

Eksportowanie metadanych

Generowanie raportów metadanych w różnych formach:

public class MetadataReportGenerator

        var viewer = new DicomMetadataViewer();
        var records = new List<string>();
        
        // Header

        var files = Directory.GetFiles(dicomDirectory, "*.dcm", SearchOption.AllDirectories);

konkluzja

Budowa przeglądarki metadanych DICOM daje niezbędne możliwości rozwoju obrazu medycznego. Niezależnie od tego, czy potrzebujesz szybkiego inspektora linii poleceń, sieci API do integracji lub narzędzi do raportowania paczek, Aspose.Medical for .NET zapewnia podstawę do ekstrakcji i analizy atrybutów DIKOM. Te techniki są cenne dla rozwiązywania problemów, zapewnienia jakości i budowania aplikacji obrazów medycznych.
