在Java項目中處理DICOM圖像,通??梢允褂瞄_源庫,如dcm4che2或PixelMed

  1. 添加依賴:首先,需要在項目中添加dcm4che2的依賴。如果你使用Maven,可以在pom.xml文件中添加以下依賴:
   <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>
  1. 讀取DICOM文件:使用dcm4che2庫讀取DICOM文件并獲取其中的圖像數(shù)據(jù)。以下是一個簡單的示例:
import org.dcm4che3.data.Attributes;
import org.dcm4che3.data.Tag;
import org.dcm4che3.io.DicomInputStream;
import org.dcm4che3.io.DicomOutputStream;

import java.io.File;
import java.io.IOException;

public class DicomReader {
    public static void main(String[] args) {
        File dicomFile = new File("path/to/your/dicom/file.dcm");
        try (DicomInputStream dis = new DicomInputStream(dicomFile)) {
            Attributes attributes = dis.readDataset(-1, -1);
            String patientName = attributes.getString(Tag.PatientName, "Unknown");
            System.out.println("Patient Name: " + patientName);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
  1. 將DICOM圖像轉(zhuǎn)換為Java圖像:使用dcm4che2的ImageIO插件將DICOM圖像轉(zhuǎn)換為Java BufferedImage。以下是一個簡單的示例:
import org.dcm4che3.imageio.plugins.dcm.DicomImageReadParam;
import org.dcm4che3.io.DicomInputStream;

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.File;
import java.io.IOException;

public class DicomToImage {
    public static void main(String[] args) {
        File dicomFile = new File("path/to/your/dicom/file.dcm");
        try (ImageInputStream iis = ImageIO.createImageInputStream(dicomFile)) {
            ImageReader reader = ImageIO.getImageReadersByFormatName("DICOM").next();
            reader.setInput(iis, false);
            ImageReadParam param = new DicomImageReadParam();
            BufferedImage image = reader.read(0, param);
            // 現(xiàn)在可以對image進行處理,例如縮放、旋轉(zhuǎn)等
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
  1. 保存Java圖像:最后,可以將處理后的Java圖像保存到文件中。以下是一個簡單的示例:
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

public class SaveImage {
    public static void main(String[] args) {
        BufferedImage image = ...; // 從上面的示例中獲取處理后的圖像
        File outputFile = new File("path/to/output/image.png");
        try {
            ImageIO.write(image, "png", outputFile);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

這些示例展示了如何在Java項目中使用dcm4che2庫處理DICOM圖像。你可以根據(jù)自己的需求對這些示例進行修改和擴展。
