使用python将Dicom标签转换为excel时出错

如何解决使用python将Dicom标签转换为excel时出错

我正在尝试将.dcm文件中的DICOM标签转换并列出到Excel中（使用pydicom），但是在转换时却显示错误

有些标签虽然以DICOM格式包含/显示数据（“ FileMetainformationGroupLength”，“ FileMetainformationVersion”，“ MediaStorageSOPClassUID”，“ MediaStorageSOPInstanceUID”，“ TransferSyntaxUID”），但在Excel文件中却显示“无”。我该如何解决？

我该如何解决？

这是我的代码：

    import xlsxwriter 
    import sys 
    import pydicom 
    import os.path
    from pydicom.valuerep import PersonName

    dcm_files = [r"C:\Users\akhil\Downloads\CD no.2\CD no.2\MedVision\image\371203\1.3.12.2.1107.5.12.7.4405.30000013122104435475000000004\1.3.12.2.1107.5.12.7.4405.30000013122104435490600001421\img_1_1_1_1.dcm"]   

    for dcm_file in dcm_files:
        ds = pydicom.filereader.dcmread(dcm_file)
        workbook = xlsxwriter.Workbook(os.path.basename(dcm_file) + '.xlsx')
        worksheet = workbook.add_worksheet()

        row = 0
        col = 0

        for keyword in keywords:
            value = ds.get(keyword,"None")
            if isinstance(value,list):
                value = ",".join([str(x) for x in value])
            elif isinstance(value,PersonName):
                value = str(value)
            worksheet.write(row,col,keyword)
            worksheet.write(row + 1,value)
            col += 1

    workbook.close()

以下是来自DICOM标签的数据：

（0002，0000）文件元信息组长度UL：188

（0002，0001）文件元信息版本OB：b'\ x00 \ x01'

（0002，0002）媒体存储SOP类UID UI：数字乳腺X射线图像存储-用于演示

（0002，0003）媒体存储SOP实例UID UI：1.3.12.2.1107.5.12.7.4405.30000013122104435490600001313

（0002，0012）实现类UID UI：1.2.40.0.13.1.1

（0002，0013）实现版本名称SH：'dcm4che-1.4.7'

解决方法

文件元元素位于FileDataset.file_meta属性中，因为它们并非严格属于SOP实例的一部分，而是在写入DICOM File Format时必需的。

>>> ds.file_meta.TransferSyntaxUID
'1.2.840.10008.1.2.1'
>>> ds.file_meta.get("TransferSyntaxUID")
'1.2.840.10008.1.2.1'

我建议您使用dicom-csv python软件包。它是专门为从存储在某个文件夹树中的dicom文件收集所有可用的元数据而设计的（它使用pydicom读取和操作dicom文件）。 https://pypi.org/project/dicom-csv/

安装（pip install dicom-csv后，您可以通过以下方式从某个文件夹的所有dicom图像中收集所有公共dicom标签：

from dicom_csv import join_tree

df = join_tree('path/to/folder',relative=False,verbose=1)

生成的pandas.DataFrame将包含不同的DICOM标签作为单独的列（pixel_array数据除外），以及几个其他列，例如FileName，HasPixelArray。
