使用PixelMed
这里的例子

import com.pixelmed.dicom.Attribute;
import com.pixelmed.dicom.AttributeList;
import com.pixelmed.dicom.AttributeTag;
import com.pixelmed.dicom.TagFromName;
import com.pixelmed.display.SourceImage;


public class DisplayImageTagsToConsole {

private static AttributeList list = new AttributeList();
public static void readDcmFile() {
    String dicomFile = "E:\\eye\\demo12.dcm";

    try {
        list.read(dicomFile);
        System.out.println("Patient Name:" + getTagInformation(TagFromName.PatientName));
            System.out.println("Patient ID:" + getTagInformation(TagFromName.PatientID));
            System.out.println("Transfer Syntax:" + getTagInformation(TagFromName.TransferSyntaxUID));
        System.out.println("SOP Class:" + getTagInformation(TagFromName.SOPClassUID));
        System.out.println("Modality:" + getTagInformation(TagFromName.Modality));
        System.out.println("Samples Per Pixel:" + getTagInformation(TagFromName.SamplesPerPixel));
        System.out.println("Photometric Interpretation:" + getTagInformation(TagFromName.PhotometricInterpretation));
        System.out.println("Pixel Spacing:" + getTagInformation(TagFromName.PixelSpacing));
        System.out.println("Bits Allocated:" + getTagInformation(TagFromName.BitsAllocated));
        System.out.println("Bits Stored:" + getTagInformation(TagFromName.BitsStored));
        System.out.println("High Bit:" + getTagInformation(TagFromName.HighBit));
        SourceImage img = new com.pixelmed.display.SourceImage(list);
        System.out.println("Number of frames " + img.getNumberOfFrames());
        System.out.println("Width " + img.getWidth());//all frames will have same width
        System.out.println("Height " + img.getHeight());//all frames will have same height  
        System.out.println("Is Grayscale? " + img.isGrayscale());
        System.out.println("Pixel Data present:" + (list.get(TagFromName.PixelData) != null));

    } catch (Exception e) {
        e.printStackTrace();
    }
}

private static String getTagInformation(AttributeTag attrTag) {
    return Attribute.getDelimitedStringValuesOrEmptyString(list, attrTag);
  }
}
