DICOM Read with Java Code Example

Introduction

In the field of medical imaging, the DICOM (Digital Imaging and Communications in Medicine) standard is widely used for storing and transmitting medical images. In this article, we will provide a code example in Java for reading DICOM files.

Prerequisites

To run the code example, you need to have the following software installed on your machine:

• Java Development Kit (JDK) version 8 or above
• Maven build tool

Code Example

The code example below shows how to read a DICOM file using the dcm4che library in Java:

import org.dcm4che3.data.Attributes;
import org.dcm4che3.io.DicomInputStream;

import java.io.File;
import java.io.IOException;

public class DicomFileReader {
    public static void main(String[] args) {
        File inputFile = new File("/path/to/dicom/file.dcm");
        try {
            DicomInputStream dicomInputStream = new DicomInputStream(inputFile);
            Attributes attributes = dicomInputStream.readDataset(-1, -1);
            dicomInputStream.close();
            // Process DICOM attributes
            String patientName = attributes.getString(Attributes.PatientName);
            System.out.println("Patient name: " + patientName);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

In the above code example, we create a File object representing the location of the input DICOM file. We then create a DicomInputStream object and pass the File object to its constructor. We call the readDataset method on the DicomInputStream object to read the DICOM attributes from the input file, and store them in an Attributes object. Finally, we process the DICOM attributes as we like, for example, we can retrieve the patient name from the Attributes object.

Conclusion

In this article, we provided a Java code example for reading a DICOM file using the dcm4che library. You can use this code as a basis for your own DICOM file reading application.
