如何利用Java實(shí)現(xiàn)Dicom圖像的可視化

要使用Java實(shí)現(xiàn)DICOM圖像的可視化，您需要遵循以下步驟：

1. 獲取DICOM庫：首先，您需要一個用于處理DICOM文件的Java庫。其中最流行的是dcm4che2和PixelMed。在這里，我們將使用dcm4che2庫。要將dcm4che2添加到項目中，請將以下依賴項添加到Maven或Gradle構(gòu)建文件中。

Maven:

   <groupId>org.dcm4che</groupId>
   <artifactId>dcm4che-core</artifactId>
   <version>5.23.0</version>
</dependency><dependency>
   <groupId>org.dcm4che</groupId>
   <artifactId>dcm4che-imageio</artifactId>
   <version>5.23.0</version>
</dependency>

Gradle:

implementation 'org.dcm4che:dcm4che-core:5.23.0'
implementation 'org.dcm4che:dcm4che-imageio:5.23.0'

2. 讀取DICOM文件：使用dcm4che2庫讀取DICOM文件并將其轉(zhuǎn)換為Java圖像對象。

import org.dcm4che3.data.Attributes;
import org.dcm4che3.data.Tag;
import org.dcm4che3.io.DicomInputStream;
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

public class DicomImageReader {
    public static BufferedImage readDicomFile(String dicomFilePath) throws IOException {
        try (DicomInputStream dis = new DicomInputStream(new File(dicomFilePath))) {
            Attributes attributes = dis.readDataset(-1, -1);
            return ImageIO.read(attributes.getBytes(Tag.PixelData));
        }
    }
}

3. 顯示DICOM圖像：創(chuàng)建一個Java Swing應(yīng)用程序，將DICOM圖像繪制到JPanel上。

import javax.swing.*;
import java.awt.*;
import java.io.IOException;

public class DicomImageViewer extends JFrame {
    private BufferedImage dicomImage;

    public DicomImageViewer(String dicomFilePath) throws IOException {
        dicomImage = DicomImageReader.readDicomFile(dicomFilePath);
        setSize(dicomImage.getWidth(), dicomImage.getHeight());
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    @Override
    public void paint(Graphics g) {
        super.paint(g);
        g.drawImage(dicomImage, 0, 0, this);
    }

    public static void main(String[] args) throws IOException {
        String dicomFilePath = "path/to/your/dicom/file.dcm";
        DicomImageViewer viewer = new DicomImageViewer(dicomFilePath);
        viewer.setVisible(true);
    }
}

現(xiàn)在，當(dāng)您運(yùn)行此程序時，它將顯示給定DICOM文件的圖像。請確保將dicomFilePath變量設(shè)置為您要查看的DICOM文件的路徑。
