基于java将dicom转化为jpg的几种方式

参考1 JAVA代码实现DICOM文件转换JPG

package com.example;
 
import java.awt.image.BufferedImage;
import java.io.File;
 
import javax.imageio.ImageIO;
 
import ij.plugin.DICOM;
 
/**
 * dicom文件java解析，生成图片
 * 不过这里不能解析压缩的dicom文件
 */
public class ImageDemo {
 
    public static void main(String args[]) {
//        create("test1.dcm");    //在本地目录生成test1.dcm.jpg图片文件
        create2("D:\\dicom\\test3.dcm");   //在电脑dicom文件夹下生成test1.dcm.jpg图片文件
 
    }
 
 
    /**
     * 根据dicom文件生成jpg图片
     * <p/>
     * 这里输入的是image文件夹的dicom文件名字，
     * 运行即可得到一个jpg图片，显示的是dicom里面的图形
     */
    private static void create(String fileName) {
        try {
            String projectPath = System.getProperty("user.dir");
            //Check class DICOM
            DICOM dicom = new DICOM();
            String imagePath = projectPath + "\\image\\" + fileName;
            dicom.run(imagePath);
            BufferedImage bi = (BufferedImage) dicom.getImage();
            int width = bi.getWidth();
            int height = dicom.getHeight();
            System.out.println("width: " + width + "\n" + "height: " + height);
            imagePath = projectPath + "\\image\\" + fileName + ".jpg";
            ImageIO.write(bi, "jpg", new File(imagePath));
            System.out.println("Hehe,Game over!!!");
 
        } catch (Exception e) {
            System.out.println("错误" + e.getMessage());
        }
 
    }
 
 
    /**
     * 输入一个dicom文件的绝对路径和名字
     * 获取一个jpg文件
     */
    private static void create2(String filePath) {
        try {
            DICOM dicom = new DICOM();
            dicom.run(filePath);
            BufferedImage bi = (BufferedImage) dicom.getImage();
            int width = bi.getWidth();
            int height = dicom.getHeight();
            System.out.println("width: " + width + "\n" + "height: " + height);
            String imagePath = filePath + ".jpg";
            ImageIO.write(bi, "jpg", new File(imagePath));
            System.out.println("Hehe,Game over!!!");
 
        } catch (Exception e) {
            System.out.println("错误" + e.getMessage());
        }
 
    }
}

参考2 使用java实现dcm文件转jpg

由于相关的jar基本直接搞不到，需要自己编译jar。这里提供直接带有jar的项目，免去编译问题，很多时候编译失败。

jar一共需要4个：

dcm4che-core-5.20.0.jar
dcm4che-imageio-5.20.0.jar
dcm4che-image-5.20.0.jar
slf4j-api-1.7.30.jar

如果能拿到这几个jar基本随便百度搜索就能解决了。

只需要一个主文件即可：

package club.kittybunny.tool.dcmfile;
import org.dcm4che3.data.Attributes;
import org.dcm4che3.imageio.plugins.dcm.DicomImageReadParam;


import javax.imageio.ImageIO;
import javax.imageio.ImageReadParam;
import javax.imageio.ImageReader;

import javax.imageio.stream.ImageInputStream;

import java.awt.image.BufferedImage;

import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.util.Iterator;


public class Dcm2Jpg2 {
    private final ImageReader imageReader = ImageIO.getImageReadersByFormatName("DICOM").next();

    private boolean preferWindow = true;
    private Attributes prState;
    private int overlayActivationMask = 0xffff;
    private int overlayGrayscaleValue = 0xffff;
    private int frame = 1;
/**

 * @param args
 * @throws Exception
 */
    public static void main(String[] args) throws Exception {
        //源文件加目录全路径，结尾用/结束，只处理里面dcm格式文件 ，例如"/home/bunny/桌面/src/"
        String src = "/home/bunny/Downloads/qq-files/1023354682/file_recv/3000566.000000-03192/";
        //目标路径全路径，将源文件加内所有dcm文件转换为同名jpg文件，使用/结束，；例如 "/home/bunny/桌面/w/dcm/"
        String out = "/home/bunny/桌面/w/dcm/";
        if (args.length >= 2) {
            src = args[0];
            out = args[1];
            
        }
        File f = new File(src);
        //读取到所有文件名
        String[] arr = f.list();
        for (int i = 0; i < arr.length; i++) {
            //筛选符合条件的文件处理
            if (arr[i].endsWith(".dcm")) {
                InputStream in = new FileInputStream(src + arr[i]);

                ByteArrayOutputStream byteArrayOutputStream = new Dcm2Jpg2().convert(in, null);
                FileOutputStream fileOutputStream = null;
                try {
                    fileOutputStream = new FileOutputStream(out + arr[i].substring(0, arr[i].lastIndexOf("."))+".jpg");
                    fileOutputStream.write(byteArrayOutputStream.toByteArray());
                } catch (IOException e) {
                    e.printStackTrace();
                }

            }
        }
        
    }

    /**

            }
            ByteArrayOutputStream os = new ByteArrayOutputStream();

            return os;
            
        } catch (IOException e) {
            e.printStackTrace();
            return null;
        }
    }

    private ImageReadParam readParam() {
        DicomImageReadParam param = (DicomImageReadParam) imageReader.getDefaultReadParam();
        param.setWindowCenter(windowCenter);
        param.setWindowWidth(windowWidth);
        param.setAutoWindowing(autoWindowing);
        param.setWindowIndex(windowIndex);
        param.setVOILUTIndex(voiLutIndex);
        param.setPreferWindow(preferWindow);
        param.setPresentationState(prState);
        param.setOverlayActivationMask(overlayActivationMask);
        param.setOverlayGrayscaleValue(overlayGrayscaleValue);
        return param;
    }

    private BufferedImage readImage(ImageInputStream iis) throws IOException {
        imageReader.setInput(iis);
        return imageReader.read(frame - 1, readParam());
    }
}

附带可执行jar的说明文件：

先将需要转换的dcm文件统一放到一个文件夹内，然后创建转换后文件的文件夹，文件夹全路径不能有空格。
执行命令例如：
java -jar dcm2jpg.jar /home/bunny/Downloads/qq-files/1023354682/file_recv/3000566.000000-03192/ /home/bunny/桌面/w/new/

其中第一个参数是源文件所在目录。
第二个参数是转换后文件艘在目录。
所有目录需要“/”结尾。

上面示例，命令中
"/home/bunny/Downloads/qq-files/1023354682/file_recv/3000566.000000-03192/"是原文件所在目录；
“/home/bunny/桌面/w/new/” 是转换后文件所在目录。

参考3 java解析dcm文件到jpg

1、下载源码编译

下载dcm3che源码
mvn install

2、gradle/maven 引用

compile (‘org.dcm4che.tool:dcm4che-tool-dcm2jpg:5.20.0’){
exclude group: ‘org.slf4j’,module: ‘slf4j-log4j12’
}

3、编写工具类

参考4 java代码使用ImageJ解析dicom文件成图片

Dicom全称是医学数字图像与通讯，这里讲java解析diocm格式文件变成jpg示例。
这里的代码只能解析普通的dicom文件成jpg图片，对于压缩的dicom文件是没有办法解析的！
ImageJ解析代码很简单，但是要导入ImageJ的jar包。
从第一个图片可以看到lib中导入了ij.jar，这就是ImageJ的jar包，下面那个zip是source文件，这样就可以看到ImageJ里面的源码。
下面是调用ImageJ的代码：

import ij.plugin.DICOM;

import java.awt.image.BufferedImage;
import java.io.File;

/**

    public static void main(String args[]) {
//        create("test1.dcm");    //在本地目录生成test1.dcm.jpg图片文件
        create2("D:\\dicom\\test3.dcm");   //在电脑dicom文件夹下生成test1.dcm.jpg图片文件

    }


    /**
     * 根据dicom文件生成jpg图片
     * <p/>
     * 这里输入的是image文件夹的dicom文件名字，
     * 运行即可得到一个jpg图片，显示的是dicom里面的图形
     */
    private static void create(String fileName) {
        try {
            String projectPath = System.getProperty("user.dir");
            //Check class DICOM
            DICOM dicom = new DICOM();
            String imagePath = projectPath + "\\image\\" + fileName;
            dicom.run(imagePath);
            BufferedImage bi = (BufferedImage) dicom.getImage();
            int width = bi.getWidth();
            int height = dicom.getHeight();
            System.out.println("width: " + width + "\n" + "height: " + height);
            imagePath = projectPath + "\\image\\" + fileName + ".jpg";
            ImageIO.write(bi, "jpg", new File(imagePath));
            System.out.println("Hehe,Game over!!!");

        } catch (Exception e) {
            System.out.println("错误" + e.getMessage());
        }

    }


    /**
     * 输入一个dicom文件的绝对路径和名字

     */
    private static void create2(String filePath) {
        try {
            DICOM dicom = new DICOM();
            dicom.run(filePath);
            BufferedImage bi = (BufferedImage) dicom.getImage();
            int width = bi.getWidth();
            int height = dicom.getHeight();
            System.out.println("width: " + width + "\n" + "height: " + height);
            String imagePath = filePath + ".jpg";
            ImageIO.write(bi, "jpg", new File(imagePath));
            System.out.println("Hehe,Game over!!!");

        } catch (Exception e) {
            System.out.println("错误" + e.getMessage());
        }
