pixelmed : 无法读取 dicom 文件

Question

I am trying to follow the tutorial at

https://saravanansubramanian.com/Saravanan/Articles_On_Software/Entries/2014/10/6_DICOM_Basics_-_Extracting_Image_Pixel_Data.html

to read dicom files. Here is some code i run

private static AttributeList list = new AttributeList();
    public static void main(String[] args) {
        String dicomFile = "/path/to/CT1_J2KR.dcm";

        try {
            list.read(dicomFile);
            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));
            OtherWordAttribute pixelAttribute = (OtherWordAttribute)(list.get(TagFromName.PixelData));
            //get the 16 bit pixel data values
            short[] data = pixelAttribute.getShortValues();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

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

but at

list.read(dicomFile);

i get

how do i fix this? Also, here is how i got the pixelmed jar

Answer 1

I have been struggling with the same issue and as far as I can tell the root problem is that the JDK has no support for JPEG2000 out-of-the box. It has nothing to do with the Pixelmed library per se. This answer lists some good options:

Using ImageIO to convert from JPEG2000 to PNG

The best long-term solution would probably be to use the OpenJPEG project, but for me it would be too cumbersome to bundle native libraries as part of my project.

I got it to work by using the jai-imageio-jpeg2000 library (simply added it as Maven dependency, no code changes required), but the licensing disclaimer listed on their GitHub page might be an issue for you.
