範例 1：建立資料存放區

下列 create-datastore 程式碼範例會建立名為 my-datastore 的資料存放區。當您在不指定 的情況下建立資料存放區時--lossless-storage-format，AWSHealthImaging 預設為 HTJ2K （高輸送量 JPEG 2000)。

aws medical-imaging create-datastore \
    --datastore-name "my-datastore"

輸出：

{
    "datastoreId": "12345678901234567890123456789012",
    "datastoreStatus": "CREATING"
}

範例 2：使用 JPEG 2000 無失真儲存格式建立資料存放區

使用 JPEG 2000 無失真儲存格式設定的資料存放區會以 JPEG 2000 格式轉碼並保留無失真影像影格。然後，可以在 JPEG 2000 無失真中擷取影像影格，而無需轉碼。下列create-datastore程式碼範例會建立名為 的 JPEG 2000 無失真儲存格式所設定的資料存放區my-datastore。

aws medical-imaging create-datastore \
    --datastore-name "my-datastore" \
    --lossless-storage-format JPEG_2000_LOSSLESS

輸出：

{
    "datastoreId": "12345678901234567890123456789012",
    "datastoreStatus": "CREATING"
}
