Creating and managing DICOM stores

This page explains how to create, edit, view, list, and delete Digital Imaging and Communications in Medicine (DICOM) stores.

DICOM stores hold DICOM instances. You can add and manage DICOM instances in a DICOM store using the DICOMweb implementation in the Cloud Healthcare API, or you can import and export DICOM instances using Google Cloud services.

For more information on how the Cloud Healthcare API conforms to the DICOM standard, see the DICOM conformance statement.

Creating a DICOM store

Before you can create a DICOM store, you need to create a dataset.

The following samples show how to create a DICOM store:

Console

To create a DICOM store:

1. In the Cloud Console, go to the Datasets page.

   Go to the Datasets page

2. Select the dataset where you want to create a DICOM store.
3. Click Create Data Store.
4. Select DICOM as the data store type.
5. Enter a name of your choice that's unique in your dataset. If the name is not unique, the data store creation fails.
6. Click Next.
7. If you want to configure a Pub/Sub topic for the data store, click Receive Cloud Pub/Sub notifications and select the topic name. When specifying a Pub/Sub topic, enter the qualified URI to the topic, as shown in the following sample:

   projects/PROJECT_ID/topics/PUBSUB_TOPIC
   

8. Click Next.
9. To add one or more labels to the store, click Add Labels to organize your data stores and enter the key/value label. For more information on resource labels, see Using resource labels.
10. Click Create.

The new data store appears in the list.

gcloud

To create a DICOM store in the dataset, run the gcloud healthcare dicom-stores create command.

• The DICOM store ID must be unique in the dataset. It can be any Unicode string from 1 through 256 characters consisting of numbers, letters, underscores, dashes, and periods.
• To notify a Pub/Sub topic of DICOM store changes, specify an existing Pub/Sub topic name using the --pubsub-topic argument. When specifying a Pub/Sub topic, enter the qualified URI to the topic, as shown in the following sample:

  projects/PROJECT_ID/topics/PUBSUB_TOPIC
  

The following sample shows how to create a DICOM store.

gcloud healthcare dicom-stores create DICOM_STORE_ID \
  --dataset=DATASET_ID \
  --location=LOCATION \
  [--pubsub-topic=projects/PROJECT_ID/topics/PUBSUB_TOPIC]

If the request is successful, the command prompt displays the following message:

Created dicomStore [DICOM_STORE_ID].

API

To create a DICOM store, use the projects.locations.datasets.dicomStores.create method.

curl

To create a DICOM store, make a POST request and specify the following information:

• The name and location of the parent dataset
• A name for the DICOM store. The DICOM store ID must be unique in its parent dataset. It can be any Unicode string from 1 through 256 characters consisting of numbers, letters, underscores, dashes, and periods.
• An access token
• Optionally, an existing Pub/Sub topic to which the Cloud Healthcare API sends notifications of DICOM store changes. See Editing a DICOM store for information on how to configure the Pub/Sub topic.
• Optionally, whether or not to send Pub/Sub notifications during bulk import. The sendForBulkImport field is only available in the v1beta1 version.

The following sample shows a POST request using curl:

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

If the request is successful, the server returns the following response in JSON format:

{
  "name": "projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/dicomStores/DICOM_STORE_ID"
}

PowerShell

To create a DICOM store, make a POST request and specify the following information:

• The name and location of the parent dataset
• A name for the DICOM store. The DICOM store ID must be unique in its parent dataset. It can be any Unicode string from 1 through 256 characters consisting of numbers, letters, underscores, dashes, and periods.
• An access token
• Optionally, an existing Pub/Sub topic to which the Cloud Healthcare API sends notifications of DICOM store changes. See Editing a DICOM store for information on how to configure the Pub/Sub topic.
• Optionally, whether or not to send Pub/Sub notifications during bulk import. The sendForBulkImport field is only available in the v1beta1 version.

The following sample shows a POST request using Windows PowerShell:

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

Invoke-WebRequest `
  -Method Post `
  -Headers $headers `
  -ContentType: "application/json; charset=utf-8" `
  -Uri "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/dicomStores?dicomStoreId=DICOM_STORE_ID" | Select-Object -Expand Content

If the request is successful, the server returns a response similar to the following sample in JSON format:

{
  "name": "projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/dicomStores/DICOM_STORE_ID"
}

Editing a DICOM store

The following samples show how to make the following changes to a DICOM store:

• Edit the Pub/Sub topic to which the Cloud Healthcare API sends notifications of DICOM store changes.
• Edit the labels. Labels are key-value pairs that help you organize your Google Cloud resources.

When specifying a Pub/Sub topic, enter the qualified URI to the topic, as shown in the following sample:

projects/PROJECT_ID/topics/PUBSUB_TOPIC

For notifications to work, you must grant additional permissions to the Cloud Healthcare Service Agent service account. For more information, see DICOM, FHIR, and HL7v2 store Pub/Sub permissions.

Console

To edit a DICOM store, complete the following steps:

1. In the Cloud Console, go to the Datasets page.

   Go to the Datasets page

2. Select the dataset containing the DICOM store you want to edit.
3. In the Data stores list, click the data store you want to edit.
4. If you want to configure a Pub/Sub topic for the data store, select the topic name from Select a Cloud Pub/Sub Topic.
5. To add one or more labels to the store, click the edit icon next to Labels, click Add label, and enter the key/value label. For more information on resource labels, see Using resource labels.
6. If you have added a label, click Save.

gcloud

To update the DICOM store, run the gcloud healthcare dicom-stores update command.

The following sample shows how to update the Pub/Sub topic for the DICOM store. gcloud tool does not support editing labels.

Optionally, you can specify whether or not to send Pub/Sub notifications during bulk import. The sendForBulkImport field is only available in the v1beta1 version.

gcloud healthcare dicom-stores update DICOM_STORE_ID \
  --dataset=DATASET_ID \
  --location=LOCATION \
  --pubsub-topic=projects/PROJECT_ID/topics/PUBSUB_TOPIC

If the request is successful, the command prompt displays the DICOM store details including the new topic name:

Updated dicomStore [DICOM_STORE_ID].
name: projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/dicom-stores/DICOM_STORE_ID
notificationConfig:
pubsubTopic: projects/PROJECT_ID/topics/PUBSUB_TOPIC
sendForBulkImport: VALUE

API

To edit a DICOM store, use the projects.locations.datasets.dicomStores.patch method.

curl

To edit a DICOM store, make a PATCH request and specify the following information:

• The name and location of the parent dataset
• The name of the DICOM store
• The metadata to update. In this example, the qualified URI to the Pub/Sub topic and the labels to update as a comma-delimited list of key-value pairs.
• An update mask
• An access token
• Optionally, whether or not to send Pub/Sub notifications during bulk import. The sendForBulkImport field is only available in the v1beta1 version.

The following sample shows a PATCH request using curl:

curl -X PATCH \
    -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
    -H "Content-Type: application/json; charset=utf-8" \
    --data "{
      'notificationConfig': {
        'pubsubTopic':'projects/PROJECT_ID/topics/PUBSUB_TOPIC'

    }" \
    "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/dicomStores/DICOM_STORE_ID?updateMask=notificationConfig,labels"

If the request is successful, the server returns a response similar to the following sample in JSON format:

{
  "name": "projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/dicomStores/DICOM_STORE_ID",
  "notificationConfig": {

The following sample shows a GET request using Windows PowerShell:

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

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

If the request is successful, the server returns a response similar to the following sample in JSON format:

{
  "name": "projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/dicomStores/DICOM_STORE_ID"
}

If you configured any fields in the DicomStore resource, they also appear in the response.

Listing the DICOM stores in a dataset

The following samples show how to list the DICOM stores in a dataset:

Console

To view the data stores in a dataset:

1. In the Cloud Console, go to the Datasets page.

   Go to the Datasets page

2. Click the ID of the dataset whose data stores you want to view.

gcloud

To list the DICOM stores in a dataset, run the gcloud healthcare dicom-stores list command.

gcloud healthcare dicom-stores list --dataset=DATASET_ID

If the request is successful, the command prompt lists the DICOM stores:

ID              LOCATION     TOPIC
DICOM_STORE_ID  LOCATION       projects/PROJECT_ID/topics/PUBSUB_TOPIC

API

To list the DICOM stores in a dataset, use the projects.locations.datasets.dicomStores.list method.

curl

To list the DICOM stores in a dataset, make a GET request and specify the following information:

• The name and location of the parent dataset
• An access token

The following sample shows a GET request using curl:

curl -X GET \
     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/dicomStores"

If the request is successful, the server returns a response similar to the following sample in JSON format:

{
  "dicomStores": [
    {
      "name": "projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/dicomStores/DICOM_STORE_ID"
    },
    {

Deleting a DICOM store

Caution: Deleting a DICOM store also deletes the object instances in the DICOM store. If deleted, this data cannot be recovered. DICOM object instances that were exported to Cloud Storage are not affected.

The following samples show how to delete a DICOM store:

Console

To delete a data store:

1. In the Cloud Console, go to the Datasets page.

   Go to the Datasets page

2. Select the dataset containing the data store you want to delete.
3. Choose Delete from the Actions drop-down list for the data store that you want to delete.
4. To confirm, type the data store name and then click Delete.

gcloud

To delete a DICOM store, run the gcloud healthcare dicom-stores delete command:

1. Run the delete command.

gcloud healthcare dicom-stores delete DICOM_STORE_ID \
  --dataset=DATASET_ID \
  --location=LOCATION

1. To confirm, type Y.

If the request is successful, the command prompt displays the following response:

Deleted dicomStore [DICOM_STORE_ID].

API

To delete a DICOM store, use the projects.locations.datasets.dicomStores.delete method.

curl

To delete a DICOM store, make a DELETE request and specify the following information:

• The name and location of the parent dataset
• The name of the DICOM store to delete
• An access token

The following sample shows a DELETE request using curl:

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth application-default print-access-token)" \
     "https://healthcare.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/datasets/DATASET_ID/dicomStores/DICOM_STORE_ID"

If the request is successful, the server returns the empty response body in JSON format:

{}
