Kako Anonimizirati Folder DICOM studija

Kako Anonimizirati Folder DICOM studija

Ovaj tutorial pokazuje kako anonimizirati više DICOM datoteka iz mape pomoću C#.Kada radite sa stotinama ili tisućama medicinskih slikarskih datotek, obrada paketa je neophodna za učinkovitost i dosljednost.

Prednosti anonimnosti Batch

  • učinkovitost:- Proizvoditi cijele studije ili arhive u jednoj operaciji.

  • Usklađenost:- Primijenite ista pravila anonimnosti na sve datoteke.

  • Automatizacija:- Integracija u automatizirane radne tokove i cijevi.

Predviđanja: Priprema za okoliš

  • Sastavite Visual Studio ili bilo koji kompatibilni .NET IDE.
  • Stvorite novi .NET 8 konzol aplikacijski projekt.
  • Instalirajte Aspose.Medical iz upravitelja paketa NuGet.
  • Pripremite ulaznu mapu s DICOM datotekama i kreirajte izlazni folder.

Korak po korak vodič za uklanjanje anonimnih DICOM datoteka

Korak 1: Instalirati Aspose.Medical

Dodajte Aspose.Medical knjižnicu u svoj projekt pomoću NuGeta.

Install-Package Aspose.Medical

Korak 2: Uključite potrebne nazivne prostore

Dodajte upute potrebnim nazivnim prostorima u vašem kodu.

using Aspose.Medical.Dicom;
using Aspose.Medical.Dicom.Anonymization;

Korak 3: Postavite direktorije putova

Definicija ulaznih i izlaznih direktorija putova.

string inputDirectory = @"C:\DicomStudies\Input";
string outputDirectory = @"C:\DicomStudies\Anonymized";

// Ensure output directory exists
Directory.CreateDirectory(outputDirectory);

Korak 4: Preuzmite DICOM datoteke

Pronađite sve DICOM datoteke iz ulaznog direktora, uključujući poddirektore.

string[] dicomFiles = Directory.GetFiles(
    inputDirectory, 
    "*.dcm", 
    SearchOption.AllDirectories
);

Console.WriteLine($"Found {dicomFiles.Length} DICOM files to process.");

Korak 5: Stvaranje anonimnog uređaja

Stvorite anonimni primjer sa željeni profil.

Anonymizer anonymizer = new();
// Or with a custom profile:
// ConfidentialityProfile profile = ConfidentialityProfile.CreateDefault(
//     ConfidentialityProfileOptions.BasicProfile
// );
// Anonymizer anonymizer = new(profile);

Korak 6: Proizvodnja svakog datoteke

Prolazite kroz svaki datoteku, anonimno ga i sačuvajte u izlazni direktorij.

int successCount = 0;
int failCount = 0;

foreach (string filePath in dicomFiles)
{
    try
    {
        // Load DICOM file
        DicomFile dcm = DicomFile.Open(filePath);
        
        // Anonymize
        DicomFile anonymizedDcm = anonymizer.Anonymize(dcm);
        
        // Preserve relative directory structure
        string relativePath = Path.GetRelativePath(inputDirectory, filePath);
        string outputPath = Path.Combine(outputDirectory, relativePath);
        
        // Ensure subdirectory exists
        Directory.CreateDirectory(Path.GetDirectoryName(outputPath)!);
        
        // Save anonymized file
        anonymizedDcm.Save(outputPath);
        
        successCount++;
        Console.WriteLine($"✓ Processed: {relativePath}");
    }
    catch (Exception ex)
    {
        failCount++;
        Console.WriteLine($"✗ Failed: {filePath} - {ex.Message}");
    }
}

Console.WriteLine($"\nCompleted: {successCount} succeeded, {failCount} failed.");

Kompletni primjer koda za anonimizaciju batch-a

Ovdje je potpuni primjer dokazivanja anonimnosti s izvješćivanjem o napretku:

using Aspose.Medical.Dicom;
using Aspose.Medical.Dicom.Anonymization;

string inputDirectory = @"C:\DicomStudies\Input";
string outputDirectory = @"C:\DicomStudies\Anonymized";

// Ensure output directory exists
Directory.CreateDirectory(outputDirectory);

// Get all DICOM files
string[] dicomFiles = Directory.GetFiles(inputDirectory, "*.dcm", SearchOption.AllDirectories);
Console.WriteLine($"Found {dicomFiles.Length} DICOM files to process.\n");

// Create anonymizer
Anonymizer anonymizer = new();

int successCount = 0;
int failCount = 0;
int total = dicomFiles.Length;

foreach (string filePath in dicomFiles)
{
    try
    {
        DicomFile dcm = DicomFile.Open(filePath);
        DicomFile anonymizedDcm = anonymizer.Anonymize(dcm);
        
        string relativePath = Path.GetRelativePath(inputDirectory, filePath);
        string outputPath = Path.Combine(outputDirectory, relativePath);
        Directory.CreateDirectory(Path.GetDirectoryName(outputPath)!);
        
        anonymizedDcm.Save(outputPath);
        successCount++;
        
        // Progress reporting
        double progress = (double)(successCount + failCount) / total * 100;
        Console.WriteLine($"[{progress:F1}%] ✓ {relativePath}");
    }
    catch (Exception ex)
    {
        failCount++;
        Console.WriteLine($"✗ Failed: {Path.GetFileName(filePath)} - {ex.Message}");
    }
}

Console.WriteLine($"\n========================================");
Console.WriteLine($"Batch Anonymization Complete");
Console.WriteLine($"Succeeded: {successCount}");
Console.WriteLine($"Failed: {failCount}");
Console.WriteLine($"========================================");

Paralelna obrada za bolju učinkovitost

Za velike zbirke podataka, koristite paralelnu obradu kako biste iskoristili više CPU korijena:

using Aspose.Medical.Dicom;
using Aspose.Medical.Dicom.Anonymization;
using System.Collections.Concurrent;

string inputDirectory = @"C:\DicomStudies\Input";
string outputDirectory = @"C:\DicomStudies\Anonymized";

Directory.CreateDirectory(outputDirectory);

string[] dicomFiles = Directory.GetFiles(inputDirectory, "*.dcm", SearchOption.AllDirectories);
Console.WriteLine($"Found {dicomFiles.Length} DICOM files to process.\n");

// Thread-safe counters
int successCount = 0;
int failCount = 0;
ConcurrentBag<string> failedFiles = new();

// Process in parallel
Parallel.ForEach(dicomFiles, new ParallelOptions { MaxDegreeOfParallelism = Environment.ProcessorCount }, filePath =>
{
    try
    {
        // Each thread gets its own anonymizer instance
        Anonymizer anonymizer = new();
        
        DicomFile dcm = DicomFile.Open(filePath);
        DicomFile anonymizedDcm = anonymizer.Anonymize(dcm);
        
        string relativePath = Path.GetRelativePath(inputDirectory, filePath);
        string outputPath = Path.Combine(outputDirectory, relativePath);
        
        lock (outputDirectory) // Ensure directory creation is thread-safe
        {
            Directory.CreateDirectory(Path.GetDirectoryName(outputPath)!);
        }
        
        anonymizedDcm.Save(outputPath);
        Interlocked.Increment(ref successCount);
    }
    catch (Exception ex)
    {
        Interlocked.Increment(ref failCount);
        failedFiles.Add($"{filePath}: {ex.Message}");
    }
});

Console.WriteLine($"\nBatch Anonymization Complete");
Console.WriteLine($"Succeeded: {successCount}");
Console.WriteLine($"Failed: {failCount}");

if (failedFiles.Any())
{
    Console.WriteLine($"\nFailed files:");
    foreach (string failure in failedFiles)
    {
        Console.WriteLine($"  - {failure}");
    }
}

Povećana verzija s logiranjem

Za proizvodno okruženje, provedite odgovarajući logging:

using Aspose.Medical.Dicom;
using Aspose.Medical.Dicom.Anonymization;

string inputDirectory = @"C:\DicomStudies\Input";
string outputDirectory = @"C:\DicomStudies\Anonymized";
string logFile = Path.Combine(outputDirectory, "anonymization_log.txt");

Directory.CreateDirectory(outputDirectory);

string[] dicomFiles = Directory.GetFiles(inputDirectory, "*.dcm", SearchOption.AllDirectories);

Anonymizer anonymizer = new();
List<string> logEntries = new();

logEntries.Add($"Anonymization started: {DateTime.Now}");
logEntries.Add($"Input directory: {inputDirectory}");
logEntries.Add($"Output directory: {outputDirectory}");
logEntries.Add($"Total files to process: {dicomFiles.Length}");
logEntries.Add("---");

int successCount = 0;
int failCount = 0;

foreach (string filePath in dicomFiles)
{
    string relativePath = Path.GetRelativePath(inputDirectory, filePath);
    
    try
    {
        DicomFile dcm = DicomFile.Open(filePath);
        DicomFile anonymizedDcm = anonymizer.Anonymize(dcm);
        
        string outputPath = Path.Combine(outputDirectory, relativePath);
        Directory.CreateDirectory(Path.GetDirectoryName(outputPath)!);
        anonymizedDcm.Save(outputPath);
        
        successCount++;
        logEntries.Add($"SUCCESS: {relativePath}");
    }
    catch (Exception ex)
    {
        failCount++;
        logEntries.Add($"FAILED: {relativePath} - {ex.Message}");
    }
}

logEntries.Add("---");
logEntries.Add($"Anonymization completed: {DateTime.Now}");
logEntries.Add($"Succeeded: {successCount}");
logEntries.Add($"Failed: {failCount}");

// Write log file
File.WriteAllLines(logFile, logEntries);

Console.WriteLine($"Processing complete. Log saved to: {logFile}");

Najbolje prakse za obradu batha

  • Run on Copy of Data: Uvijek obrađujemo kopiju vaših izvornih podataka, a ne originalnih podataka.
  • Log Sve operacije: Čuvajte detaljne logove koje su datoteke obrađene i bilo kakve pogreške.
  • Test First: Radite na malom uzorku prije obrade cijelog zbirke podataka.
  • Monitor Disk Space: osigurava dovoljno prostora na disku za izlazne datoteke.
  • Trade Interruptions: Razmislite o implementaciji funkcije checkpoint/resume za vrlo velike partije.

Troubleshooting

Problemi s pamćenjem s velikim zbirkama podataka

Za vrlo velike datoteke ili skupove podataka, obrađivanje dosjea jedan po jedan bez zadržavanja referencija:

foreach (string filePath in dicomFiles)
{
    using (DicomFile dcm = DicomFile.Open(filePath))
    {
        DicomFile anonymizedDcm = anonymizer.Anonymize(dcm);
        anonymizedDcm.Save(outputPath);
    }
    // Files are disposed after each iteration
}

pogreške dopuštenja

Uvjerite se da je vaša aplikacija pročitao pristup ulaznom direktoriju i napisati pristup izlasku.

zaključak

Ovaj tutorial je pokazao kako sačuvati anonimne DICOM datoteke u C# pomoću Aspose.Medical. Bilo da se obrađuju stotine ili tisuće datotek, pristupa sažuvaju osigurava dosljednu anonymizaciju diljem cijelog zbirke podataka, a istodobno pruža praćenje napretka i rješavanje pogrešaka za pouzdanost proizvodnje.
