使用客户端库存储医疗保健数据

使用客户端库存储医疗保健数据

本页面介绍如何使用 Cloud Healthcare API 和 Google API 客户端库完成以下任务:

  1. 创建 Cloud Healthcare API 数据集。
  2. 在数据集内创建以下数据存储区之一:
    • 医学数字图像和通信 (DICOM) 存储区
    • 快速医疗互操作性资源 (FHIR) 存储区
    • Health Level Seven International 版本 2 (HL7v2) 存储区
  3. 在 DICOM、FHIR 或 HL7v2 存储区中存储和检查特定类型的医疗数据。

如果您只想使用一种类型的数据存储区,可以在完成准备工作创建数据集中的步骤后直接跳到快速入门的相应部分。

准备工作

  1. 登录您的 Google Cloud 帐号。如果您是 Google Cloud 新手,请创建一个帐号来评估我们的产品在实际场景中的表现。新客户还可获享 $300 赠金,用于运行、测试和部署工作负载。
  2. 安装 Google Cloud CLI。
  3. 如需初始化 gcloud CLI,请运行以下命令:

    gcloud init
  4. 创建或选择 Google Cloud 项目。

    • 创建 Google Cloud 项目:

      gcloud projects create PROJECT_ID
    • 选择您创建的 Google Cloud 项目:

      gcloud config set project PROJECT_ID
  5. 确保您的 Google Cloud 项目已启用结算功能

  6. Enable the Cloud Healthcare API:

    gcloud services enable healthcare.googleapis.com
  7. 为您的 Google 帐号创建本地身份验证凭据:

    gcloud auth application-default login
  8. 向您的 Google 账号授予角色。对以下每个 IAM 角色运行以下命令一次: roles/healthcare.datasetAdmin, roles/healthcare.fhirStoreAdmin, roles/healthcare.dicomStoreAdmin, roles/healthcare.hl7V2StoreAdmin

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:EMAIL_ADDRESS" --role=ROLE
    • PROJECT_ID 替换为您的项目 ID。
    • EMAIL_ADDRESS 替换为您的电子邮件地址。
    • ROLE 替换为每个角色。
  9. 安装 Google Cloud CLI。
  10. 如需初始化 gcloud CLI,请运行以下命令:

    gcloud init
  11. 创建或选择 Google Cloud 项目。

    • 创建 Google Cloud 项目:

      gcloud projects create PROJECT_ID
    • 选择您创建的 Google Cloud 项目:

      gcloud config set project PROJECT_ID
  12. 确保您的 Google Cloud 项目已启用结算功能

  13. Enable the Cloud Healthcare API:

    gcloud services enable healthcare.googleapis.com
  14. 为您的 Google 帐号创建本地身份验证凭据:

    gcloud auth application-default login
  15. 向您的 Google 账号授予角色。对以下每个 IAM 角色运行以下命令一次: roles/healthcare.datasetAdmin, roles/healthcare.fhirStoreAdmin, roles/healthcare.dicomStoreAdmin, roles/healthcare.hl7V2StoreAdmin

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:EMAIL_ADDRESS" --role=ROLE
    • PROJECT_ID 替换为您的项目 ID。
    • EMAIL_ADDRESS 替换为您的电子邮件地址。
    • ROLE 替换为每个角色。

在 Cloud Healthcare API 中存储和查看 DICOM 实例后,请继续清理,以免因本页面上使用的资源导致您的 Google Cloud 帐号产生费用。

如需详细了解如何使用 DICOM 数据,请参阅后续步骤

存储和查看 FHIR 资源

本部分介绍了如何完成以下任务:

  1. 创建 FHIR 存储区。
  2. 在 FHIR 存储区中存储 FHIR 资源。
  3. 查看 FHIR 资源的数据。

Cloud Healthcare API 实现了 FHIR 规范标准,用于存储和访问 FHIR 数据。

创建 FHIR 存储区

FHIR 存储区位于数据集内,用于存储 FHIR 资源。请运行以下示例以创建 FHIR 存储区。

在运行示例之前,请根据需要取消注释并提供以下值:

  • 您在准备工作部分中创建或选择的 Google Cloud 项目的 ID 作为项目 ID
  • my-dataset 用于数据集 ID
  • us-central1 - 数据集位置
  • my-fhir-store 用于 FHIR 存储区 ID

  1. 创建 HL7v2 存储区
  2. 将 HL7v2 消息存储在 HL7v2 存储区中。
  3. 查看 HL7v2 消息的数据。

Cloud Healthcare API 中的 HL7v2 实现符合 HL7v2 标准

HL7v2 存储区位于数据集内,用于存储 HL7v2 数据。请运行以下示例以创建 HL7v2 存储区。

在运行示例之前,请根据需要取消注释并提供以下值:

  • 您在准备工作部分中创建或选择的 Google Cloud 项目的 ID 作为项目 ID
  • my-dataset 用于数据集 ID

创建 HL7v2 消息

  1. 示例 HL7v2 消息文件下载到您的机器上:

    curl

    curl -O https://cloud.google.com/healthcare-api/docs/resources/hl7v2-sample.json
    

    PowerShell

    Invoke-WebRequest -Uri "https://cloud.google.com/healthcare-api/docs/resources/hl7v2-sample.json" -OutFile $pwd/hl7v2-sample.json
    

    HL7v2 消息包含以下基本信息,它采用 base-64 编码存放在示例文件的 data 字段中:

    MSH|^~\&|A|SEND_FACILITY|A|A|20180101000000||TYPE^A|20180101000000|T|0.0|||AA||00|ASCII

在 Cloud Healthcare API 中存储和查看 HL7v2 消息后,请继续清理,以避免因本页面中使用的资源导致您的 Google Cloud 帐号产生费用。

如需详细了解如何使用 HL7v2 数据,请参阅后续步骤

清理

为避免因本页面中使用的资源导致您的 Google Cloud 账号产生费用,请删除包含这些资源的 Google Cloud 项目。

如果您为此快速入门创建了新项目,请按照删除项目中的步骤操作。否则,请按照删除数据集中的步骤操作。

  1. 可选:撤消您创建的身份验证凭据,并删除本地凭据文件。

    gcloud auth application-default revoke
  2. 可选:从 gcloud CLI 撤消凭据。

    gcloud auth revoke

删除项目

    删除 Google Cloud 项目:

    gcloud projects delete PROJECT_ID

删除数据集

如果您不再需要在本快速入门中创建的数据集,可以将其删除。删除数据集会永久删除该数据集以及其中包含的任何 FHIR、HL7v2 或 DICOM 存储区。

在运行示例之前,请根据需要取消注释并提供以下值:

  • 您在准备工作部分中创建或选择的 Google Cloud 项目的 ID 作为项目 ID
  • my-dataset 用于数据集 ID
  • us-central1 - 数据集位置
