如何将dicom文件转换为jpg转换 [英] How to convert dicom file to jpg conversion

问题描述

我们如何使用java将dicom文件（.dcm）转换为jpeg图像？
这是我的代码：

How we can convert a dicom file(.dcm) to a jpeg image using java? Here is my code:

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

and i am getting the following error while running the project

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/cli/ParseException

推荐答案

这是链接使用dcm4che 2将DICOM转换为JPEG

以下是我的代码，它完美地运行。我已将它放入导入，因此可能是使用完全。

Following is my code which works perfectly.I have placed it with imports so it might be use-full.

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");
        }

    }
}
