dcm4che是一个用于处理DICOM（数字影像和通信医疗图像的通信）协议的Java库。下面是一个简单的示例代码，用于从DICOM协议文件中获取图像：

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 void main(String[] args) {
        String dicomFilePath = "/path/to/dicom/file.dcm";

        try (DicomInputStream dis = new DicomInputStream(new File(dicomFilePath))) {
            Attributes attrs = dis.readDataset(-1, -1);
            
            // 获取图像的宽度和高度
            int width = attrs.getInt(Tag.Columns, 0);
            int height = attrs.getInt(Tag.Rows, 0);
            
            // 获取图像数据
            byte[] pixelData = attrs.getBytes(Tag.PixelData);
            
            // 创建一个BufferedImage对象
            BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_USHORT_GRAY);

            // 将图像数据写入BufferedImage对象
            image.getRaster().setDataElements(0, 0, width, height, pixelData);
            
            // 保存图像到文件
            String outputFilePath = "/path/to/output/image.png";
            ImageIO.write(image, "png", new File(outputFilePath));
            
            System.out.println("图像成功保存到文件：" + outputFilePath);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

请将`/path/to/dicom/file.dcm`替换为你实际的DICOM协议文件路径，并将`/path/to/output/image.png`替换为你想要保存图像的输出路径。这段代码将读取DICOM文件，提取图像的宽度、高度和像素数据，并将图像保存为PNG格式的文件。

使用dcm4che库从dicom协议文件中获取图片的Java代码如下：

import org.dcm4che3.data.*;
import org.dcm4che3.io.*;
import org.dcm4che3.util.*;

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.*;
import java.nio.file.Files;
import java.nio.file.Paths;

public class DICOMImageExtractor {
    public static void main(String[] args) {
        String dicomFilePath = "path_to_dicom_file.dcm";
        
        try {
            DicomInputStream dicomInputStream = new DicomInputStream(new FileInputStream(dicomFilePath));
            DicomObject dicomObject = dicomInputStream.readDicomObject();

            Attribute pixelData = dicomObject.get(Tag.PixelData);
            byte[] pixelDataBytes = pixelData.getByteValues();

            String photometricInterpretation = dicomObject.getString(Tag.PhotometricInterpretation);
            int bitsAllocated = dicomObject.getInt(Tag.BitsAllocated);
            int rows = dicomObject.getInt(Tag.Rows);
            int columns = dicomObject.getInt(Tag.Columns);

            BufferedImage image = ImageUtil.convertToImage(pixelDataBytes, photometricInterpretation, bitsAllocated, rows, columns);

            String outputImagePath = "path_to_output_image.jpg";
            ImageIO.write(image, "jpg", new File(outputImagePath));

            System.out.println("Image extraction complete.");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

以上代码使用dcm4che库中的`DicomInputStream`类读取dicom文件，并使用`DicomObject`类获取图片信息。然后，通过`ImageUtil.convertToImage`方法将获取的像素数据转换为`BufferedImage`对象。最后，使用`ImageIO.write`方法保存图片为JPEG格式。请根据实际情况根据路径填写正确的dicom文件路径和输出图片的路径。

给出java代码使用dcm4che库获取dcm4chee服务的dicom文件

以下是使用dcm4che库获取dcm4chee服务的Dicom文件的Java代码示例：

import org.dcm4che3.data.Attributes;
import org.dcm4che3.data.Tag;

import org.dcm4che3.net.service.QueryRetrieveSCP;
import org.dcm4che3.net.service.QueryRetrieveService;
import org.dcm4che3.util.SafeClose;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.net.Socket;
import java.util.List;

public class DicomRetrieveExample {

    public static void main(String[] args) throws Exception {
        // 连接dcm4chee服务
        Device device = new Device("retrieve");
        Connection conn = new Connection();
        conn.setHostname("dcm4chee-server");
        conn.setPort(11112);
        device.setConnection(conn);
        ApplicationEntity ae = new ApplicationEntity("retrieve");
        ae.addConnection(conn);
        device.addApplicationEntity(ae);
        device.setAssociationInitiator(true);
        device.setPackPDV(true);
        device.setTcpNoDelay(true);

        device.setRspTimeout(5000);
        device.setAssociationAcceptor(true);
        device.setAsyncOpsWindow(0, 1);
        device.setMaxAsyncOpsInvoked(1);
        device.setMaxAsyncOpsPerformed(1);
        device.setStorageSCP(new QueryRetrieveSCP("*") {
            @Override
            protected void store(Socket socket, InputStream data, int pcid, String tsuid, Attributes attrs, Attributes rsp)
                    throws IOException, DicomServiceException {
                // 不存储
            }
        });
        device.startListening();

        // 检索Dicom文件
        QueryRetrieveService qrService = ae.getDevice().getQrService();
        qrService.setQueryOptions(QueryOption.RELATIONAL);
        qrService.setRetrieveTimeout(10000);
        qrService.setCMoveDestination(conn.getCalledAET());
        List<String> studies = qrService.queryStudies("*");
        for (String study : studies) {
            List<String> series = qrService.querySeries(study, "*");
            for (String serie : series) {
                List<String> instances = qrService.queryInstances(serie, "*");
                for (String instance : instances) {
                    // 获取Dicom文件
                    DicomInputStream dis = null;
                    FileOutputStream fos = null;
                    try {
                        dis = new DicomInputStream(qrService.retrieveInstance(instance));
                        Attributes attrs = dis.readDataset(-1, -1);
                        // 保存Dicom文件
                        File outputFile = new File("path/to/output/file.dcm");
                        fos = new FileOutputStream(outputFile);
                        fos.write(dis.readBytes());
                    } finally {
                        SafeClose.close(fos);
                        SafeClose.close(dis);
                    }
                }
            }
        }

        // 断开连接
        device.stopListening();
        device.unbindConnections();
    }

}

这个示例演示了如何使用dcm4che库从dcm4chee服务检索Dicom文件。首先，使用dcm4che库连接dcm4chee服务。然后，使用dcm4chee服务的QueryRetrieveService查询Dicom文件，获取Dicom文件并保存它们。最后，断开连接。

请将`dcm4chee-server`替换为dcm4chee服务的主机名或IP地址，并将`path/to/output/file.dcm`替换为要保存的文件路径。
