我正在尝试按照教程

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

读取 dicom 文件。这是我运行的一些代码

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);
    }

但在

list.read(dicomFile);

我明白了

我该如何解决？另外，这是我得到pixelmed jar的方法

我一直在努力解决同样的问题，据我所知，根本问题是 JDK 不支持开箱即用的 JPEG2000。它与 Pixelmed 库本身无关。这个答案列出了一些不错的选择：

使用 ImageIO 将 JPEG2000 转换为 PNG

最好的长期解决方案可能是使用 OpenJPEG 项目，但对我来说，将本机库捆绑为我的项目的一部分太麻烦了。

我通过使用jai-imageio-jpeg2000库使其工作（只需将其添加为 Maven 依赖项，无需更改代码），但其 GitHub 页面上列出的许可免责声明可能对您来说是个问题。
