データセットの作成と管理

このページでは、データセットを作成、編集、表示、一覧表示、削除する方法について説明します。データセットを作成したら、電子医療記録と医用画像データを保持するデータストアを作成し、データセットを匿名化できます。

準備

Cloud Healthcare API のデータモデルをご覧ください。

データセットの作成

以下のサンプルは、データセットの作成方法を示しています。

コンソール

  1. Google Cloud コンソールの [ブラウザ] ページに移動します。

    [ブラウザ] に移動

  2. [データセットを作成] をクリックします。[データセットのプロパティ] ページが表示されます。

  3. [名前] フィールドに、データセットで使用可能な文字とサイズの要件の対象となるデータセットの識別子を入力します。

  4. 次のいずれかのロケーション タイプを選択します。

    • Region を使用します。リージョン: データセットは、1 つの Google Cloud リージョン内に永続的に存在します。このオプションを選択したら、[リージョン] フィールドにロケーションを入力するか選択します。

    • マルチリージョンデータセットは、複数の Google Cloud リージョンにまたがるロケーションに永続的に存在します。このオプションを選択したら、[マルチリージョン] フィールドでマルチリージョン ロケーションを入力または選択します。

  5. [作成] をクリックします。[ブラウザ] ページが表示されます。新しいデータセットがデータセットのリストに表示されます。

gcloud

gcloud healthcare datasets create コマンドを実行します。

後述のコマンドデータを使用する前に、次のように置き換えます。

次のコマンドを実行します。

Linux、macOS、Cloud Shell

gcloud healthcare datasets create DATASET_ID \
  --location=LOCATION

Windows(PowerShell)

gcloud healthcare datasets create DATASET_ID `
  --location=LOCATION

Windows(cmd.exe)

gcloud healthcare datasets create DATASET_ID ^
  --location=LOCATION

次のようなレスポンスが返されます。

Create request issued for: [DATASET_ID]
Created dataset [DATASET_ID].

REST

projects.locations.datasets.create メソッドを使用します。

  1. データセットの作成

    リクエストのデータを使用する前に、次のように置き換えます。

    リクエストを送信するには、次のいずれかのオプションを選択します。

    curl

    次のコマンドを実行します。

    curl -X POST \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    -d "" \
    "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets?datasetId=DATASET_ID"

    PowerShell

    次のコマンドを実行します。

    $cred = gcloud auth print-access-token
    $headers = @{ "Authorization" = "Bearer $cred" }

    Invoke-WebRequest `
    -Method POST `
    -Headers $headers `
    -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets?datasetId=DATASET_ID" | Select-Object -Expand Content

    API Explorer

    メソッド リファレンス ページを開きます。ページの右側に [API Explorer] パネルが開きます。このツールを操作してリクエストを送信できます。必須項目を入力して、[Execute] をクリックします。

    次のとおり出力されます。レスポンスには、長時間実行オペレーション(LRO)の識別子が含まれます。長時間実行オペレーションは、メソッドの呼び出しが完了するまでに時間がかかる場合に返されます。OPERATION_IDの値をメモします。この値は次の手順で必要になります。

  2. projects.locations.datasets.operations.get メソッドを使用して、長時間実行オペレーションのステータスを取得します。

    リクエストのデータを使用する前に、次のように置き換えます。

    • PROJECT_ID: Google Cloud プロジェクトの ID
    • LOCATION: データセットの場所
    • DATASET_ID: 作成するデータセットの ID
