如何将dicom文件转换为jpg转换

Question

如何使用Java将Dicom文件（.dcm）转换为jpeg图像？这是我的代码：

import java.io.File;
import java.io.IOException;
import org.dcm4che2.tool.dcm2jpg.Dcm2Jpg;
public class MainClass {
public static void main(String[] args) throws IOException{
Dcm2Jpg conv = new Dcm2Jpg();
conv.convert(new File("C:\\Users\\lijo.joseph\\Desktop\\Dicom\\IM-0001-0001.dcm"), new File("C:\\Users\\lijo.joseph\\Desktop\\Dicom\\IM-0001-0001.jpg"));
}
}

我在运行项目时遇到以下错误

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException
at MainClass.main(MainClass.java:7)
Caused by: java.lang.ClassNotFoundException: org.apache.commons.cli.ParseException

这是使用dcm4che 2将DICOM转换为JPEG的链接

以下是我的代码，效果很好，我将其与导入一起放置，因此可能用完了。

import java.awt.image.BufferedImage;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.Iterator;
import javax.imageio.ImageIO;
import javax.imageio.ImageReader;
import javax.imageio.stream.ImageInputStream;
import org.dcm4che2.imageio.plugins.dcm.DicomImageReadParam;
import com.sun.image.codec.jpeg.JPEGCodec;
import com.sun.image.codec.jpeg.JPEGImageEncoder;

public class Examplke1 {

    static BufferedImage myJpegImage=null;

    public static void main(String[] args) {
        File file = new File("test5/12840.dcm");
        Iterator<ImageReader> iterator =ImageIO.getImageReadersByFormatName("DICOM");
        while (iterator.hasNext()) {
            ImageReader imageReader = (ImageReader) iterator.next();
            DicomImageReadParam dicomImageReadParam = (DicomImageReadParam) imageReader.getDefaultReadParam();
            try {
                ImageInputStream iis = ImageIO.createImageInputStream(file);
                imageReader.setInput(iis,false);
                myJpegImage = imageReader.read(0, dicomImageReadParam);
                iis.close();
                if(myJpegImage == null){
                    System.out.println("Could not read image!!");
                }
            } catch (IOException e) {
                e.printStackTrace();
            }
            File file2 = new File("/test.jpg");
            try {
                OutputStream outputStream = new BufferedOutputStream(new FileOutputStream(file2));
                JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(outputStream);
                encoder.encode(myJpegImage);
                outputStream.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
            System.out.println("Completed");
        }

    }
}

用于运行它的罐子

1. dcm4che-imageio-2.0.28.jar
2. dcm4che-image-2.0.28.jar
3. jai_imageio-1.1.jar
4. dcm4che-core-2.0.28.jar
5. slf4j-api-1.7.7.jar
6. slf4j-log4j12-1.7.7.jar
7. apache-logging-log4j.jar

希望能帮助到你。
