Aspose.Medical for .NET 25.4 Release Notes

Major Features

We are pleased to announce the initial release of Aspose.Medical for .NET. This first version focuses on DICOM file format support with the following key features:

• DICOM Reading API: Read and parse DICOM files with full access to metadata, pixel data, and all DICOM elements.
• DICOM Writing API: Create new DICOM files from scratch or modify existing ones with an intuitive API.
• Anonymization API: Easily anonymize patient information in DICOM files while preserving image and diagnostic data.
• Transcoding Support: Change DICOM transfer syntax (transcode) between different compression formats.

As this is our first release, there are some limitations to be aware of:

• Limited support for certain JPEG codecs
• Some advanced DICOM features will be added in subsequent releases
• Performance optimizations will continue in future versions

The functionality of the library will be expanded with each subsequent release to include support for HL7, FHIR, and other healthcare data standards.

Public API Overview

This section lists the key components of the public API that were introduced in Aspose.Medical 25.4.

DICOM Reading and Accessing

The DicomFile class provides methods to load and access DICOM files:

// Load a DICOM file
DicomFile dicomFile = new DicomFile("sample.dcm");

// Access metadata
string patientName = dicomFile.Dataset.GetString(DicomTag.PatientName);
string studyDate = dicomFile.Dataset.GetString(DicomTag.StudyDate);

// Access image data
DicomImage image = new DicomImage(dicomFile);
int width = image.Width;
int height = image.Height;

DICOM Creation

The API allows creating new DICOM files from scratch:

// Create a new DICOM file
DicomFile newFile = new DicomFile();
var dataset = newFile.Dataset;

// Add metadata
dataset.Add(DicomTag.PatientName, "DOE^JOHN");
dataset.Add(DicomTag.PatientID, "12345");
dataset.Add(DicomTag.StudyDate, DateTime.Now.ToString("yyyyMMdd"));

// Add pixel data
// [...code to add pixel data omitted for brevity...]

// Save the file
newFile.Save("new_dicom.dcm");

Anonymization

The anonymization feature allows removing patient identifiable information:

// Load a DICOM file
DicomFile dicomFile = new DicomFile("patient_scan.dcm");

// Create anonymizer with default settings
DicomAnonymizer anonymizer = new DicomAnonymizer();

// Apply anonymization
anonymizer.Anonymize(dicomFile);

// Save anonymized file
dicomFile.Save("anonymized_scan.dcm");

Transfer Syntax Transcoding

Change DICOM compression format:

// Load a DICOM file
DicomFile dicomFile = new DicomFile("original.dcm");

// Change transfer syntax to JPEG Lossless
DicomTranscoder transcoder = new DicomTranscoder();
transcoder.ChangeTransferSyntax(dicomFile, DicomTransferSyntax.JPEGLossless);

// Save transcoded file
dicomFile.Save("transcoded.dcm");
