对于 AWS HealthImaging 的 DICOM 支持

AWS HealthImaging 支持特定DICOM元素和传输语法。熟悉支持的患者、研究和系列级别DICOM的数据元素，因为 HealthImaging 元数据密钥是基于它们的。在开始导入之前，请验证您的医学影像数据是否符合 HealthImaging支持的传输语法和DICOM元素限制。

注意

AWS HealthImaging 目前不支持二进制分割图像或图标图像序列像素数据。

支持的SOP类

使用 AWS HealthImaging，您可以导入使用任何SOP类编码的 DICOM P10 Service-Object Pair (SOP) 实例UID，包括已停用和私有类。所有私有属性也都将被保留。

元数据标准化

将 DICOM P10 数据导入时 AWS HealthImaging，它会转换为由元数据和图像框（像素数据）组成的图像集。在转换过程中，将根据DICOM标准的特定版本生成 HealthImaging 元数据密钥。 HealthImaging 目前基于 DICOMPS3.6 2022b 数据字典生成并支持元数据密钥。

AWS HealthImaging 支持患者、研究和系列级别的以下DICOM数据元素。

注意

有关每个患者等级元素的详细描述，请参阅DICOM数据元素注册表。

支持的传输语法

AWS HealthImaging 支持使用不同的传输语法导入 DICOM P10 文件。有些文件在导入过程中保留其原始传输语法编码，而另一些文件则默认转码为HTJ2K无损。以下示例显示了如何在返回StoredTransferSyntaxUID的元数据中 HealthImaging 记录每个实例的GetImageSetMetadata。

"Instances": {
   "999.999.2.19941105.134500.2.101": {
       "StoredTransferSyntaxUID": "1.2.840.10008.1.2.4.50",
       "ImageFrames": [{ ...
注意

查看下表时，请记住以下几点：

  • 标有星号 (*) 的传输语法UID条目表示文件在导入期间以其原始编码格式存储。对于这些文件，StoredTransferSyntaxUID位于实例元数据中的与原始传输语法相匹配。

  • 不带星号的传输语法UID条目表示文件在导入过程中被转码为HTJ2K无损并存储在中。 HealthImaging对于这些文件，StoredTransferSyntaxUID位于实例元数据中的是 “高吞吐量 JPEG 2000”，带有 “图像压缩-仅限无损RPCL” 选项 (1.2.840.10008.1.2.4.202)。

  • 如果StoredTransferSyntaxUID密钥不存在或设置为null，则可以假设它被编码为HTJ2K无损 (1.2.840.10008.1.2.4.202RPCL)。

DICOM元数据限制

当您使用UpdateImageSetMetadata更新 HealthImaging 元数据属性时，将应用以下DICOM约束。

  • 除非更新约束同时updatableAttributes适用于和，否则无法更新或移除Patient/Study/Series/Instance关卡属性的私有属性 removableAttributes

  • 无法更新以下AWS HealthImaging 生成的属性：SchemaVersionDatastoreID、ImageSetID、PixelData、Checksum、Width、Height、MinPixelValue、MaxPixelValue、FrameSizeInBytes

  • 除非设置了force标志，否则无法更新以下DICOM属性：Tag.PixelData、Tag.StudyInstanceUID、Tag.SeriesInstanceUID、Tag.SOPInstanceUID、Tag.StudyID

  • 除非设置了force标志，否则无法更新 VR 类型 SQ 的属性（嵌套属性）

  • 除非设置了force标志，否则无法更新多值属性

  • 除非设置了force标志，否则无法使用与 VR 属性类型不兼容的值来更新属性

  • 除非设置了标force志，否则无法更新根据DICOM标准不被视为有效属性的属性

  • 无法跨模块更新属性。例如，如果在客户有效载荷请求的研究级别给出了患者级别的属性，则该请求可能会失效。

  • 如果相关属性模块不存在于现有的 ImageSetMetadata 中，则无法更新属性。例如，如果现有影像集元数据中不存在带有 seriesInstanceUID 的序列，则不允许更新 seriesInstanceUID 的属性。
