DICOM
DICOM（Digital Imaging and Communications in Medicine，医学数字成像和通信）是一种用于存储和传输医学影像数据的国际标准。
版本
自从 1985 年首次发布以来，DICOM 标准已经经历了多次修订和扩展，以适应不断发展的医学影像技术和需求。当前最新版本为 2025e，历史版本可见 历史版本 和 各版本多种文件格式归档。
数据字典
DICOM 数据字典定义了 DICOM 文件中使用的各种数据元素及其属性。以下是一些常见的数据元素及其含义：
| 标签 (Tag) | 名称 (Name) | VR (Value Representation) | VM (Value Multiplicity) | 说明 (Description) |
|---|---|---|---|---|
| (0010,0010) | Patient’s Name | PN | 1 | 患者姓名 |
| (0010,0020) | Patient ID | LO | 1 | 患者标识 |
| (0008,0060) | Modality | CS | 1 | 检查模态（如 CT、MR、US 等） |
| (0028,0010) | Rows | US | 1 | 图像的行数 |
| (0028,0011) | Columns | US | 1 | 图像的列数 |
| (0028,0030) | Pixel Spacing | DS | 2 | 像素间距（行间距和列间距，单位为毫米） |
| (0028,1050) | Window Center | DS | 1-n | 窗口中心值 |
| (0028,1051) | Window Width | DS | 1-n | 窗口宽度值 |
| (0028,0008) | Number of Frames | IS | 1 | 图像的帧数（对于多帧图像） |
以上仅为部分常见的数据元素，DICOM 数据字典包含了数千个数据元素，涵盖了医学影像的各个方面。完整的数据字典可以在 DICOM 标准的第 6 部分 DICOM PS3.6 2025e - Data Dictionary 中找到。
标准中将数据元素分成了四类：
- DICOM Data Elements
- DICOM File Meta Elements
- DICOM Directory Structuring Elements
- DICOM Dynamic RTP Payload Elements
每类均以表格形式列出，如：
| Tag | Name | Keyword | VR | VM | |
|---|---|---|---|---|---|
| (0008,0001) | Length to End | LengthToEnd | UL | 1 | RET |
| (0008,0005) | Specific Character Set | SpecificCharacterSet | CS | 1-n | |
| … | … | … | … | … | … |
其中：
- Tag：数据元素的标签，相当于唯一 ID，由两个十六进制数字组成，分别表示组号和元素号，标准数据元素的组号为偶数，私有数据元素组号为奇数。
- Name：数据元素的名称，描述了该元素的含义。
- Keyword：数据元素的关键字，通常是名称的简写形式。
- VR (Value Representation)：数据元素的值表示，定义了该元素的数据类型，如：UL（Unsigned Long）、CS（Code String）、PN（Person Name）等，完整的 VR 值列表可见 Table 6.2-1. DICOM Value Representations。
- VM (Value Multiplicity)：数据元素的值多重性，表示该元素可以包含多少个值（如单值、多值等）。
pydicom
pydicom 是一个用于处理 DICOM 文件的 Python 库。它允许用户读取、修改和创建 DICOM 文件，支持大部分 DICOM 标准的数据元素和功能。
pydicom 使用内置的数据字典来解释 DICOM 文件中的数据元素。该数据字典包含了 DICOM 标准中定义的（除 Dynamic RTP Payload Elements 外）所有数据元素及其属性，可在 _dicom_dict.py 文件中对照标准查看。
示例代码
下面的代码演示了如何使用 pydicom 读取 DICOM 文件中的元素及图像。
