dcm4che3生成dicom缩略图的代码

你可以使用以下代码生成 DICOM 缩略图：

import org.dcm4che3.imageio.plugins.dcm.DicomImageReadParam;
import javax.imageio.ImageIO;
import javax.imageio.ImageReader;
import javax.imageio.stream.ImageInputStream;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.util.Iterator;

public class DicomThumbnailGenerator {
    public static void main(String[] args) throws IOException {
        File dicomFile = new File("path/to/dicom/file.dcm");
        File thumbnailFile = new File("path/to/thumbnail/file.jpg");

        ImageInputStream iis = ImageIO.createImageInputStream(dicomFile);
        Iterator<ImageReader> readers = ImageIO.getImageReaders(iis);

        if (!readers.hasNext()) {
            throw new RuntimeException("No DICOM ImageReader found!");
        }

        ImageReader reader = readers.next();
        reader.setInput(iis);

        DicomImageReadParam param = (DicomImageReadParam) reader.getDefaultReadParam();
        BufferedImage image = reader.read(, param);

        ImageIO.write(image, "jpg", thumbnailFile);
    }
}

这段代码使用 dcm4che3 库中的 `DicomImageReadParam` 类来读取 DICOM 文件，并将其转换为缩略图。注意，需要将 `path/to/dicom/file.dcm` 和 `path/to/thumbnail/file.jpg` 替换为实际的文件路径。
