BigQueryDestination

The BigQuery table where the server writes the output.

Fields
table_uri

string

BigQuery URI to a table, up to 2000 characters long, in the format bq://projectId.bqDatasetId.tableId
force

bool

Use write_disposition instead. If write_disposition is specified, this parameter is ignored. force=false is equivalent to write_disposition=WRITE_EMPTY and force=true is equivalent to write_disposition=WRITE_TRUNCATE.
write_disposition

WriteDisposition

Determines whether the existing table in the destination is to be overwritten or appended to. If a write_disposition is specified, the force parameter is ignored.

WriteDisposition

The BigQuery WriteDisposition used by the export operation.

Enums
WRITE_DISPOSITION_UNSPECIFIED Default behavior is the same as WRITE_EMPTY.
WRITE_EMPTY Only export data if the destination table is empty.
WRITE_TRUNCATE Erase all existing data in the destination table before writing the instances.
WRITE_APPEND Append data to the destination table.

CreateDicomStoreRequest

Creates a new DICOM store.

Fields
parent

string

Required. The name of the dataset this DICOM store belongs to.

Authorization requires the following IAM permission on the specified resource parent:

  • healthcare.dicomStores.create
dicom_store_id

string

Required. The ID of the DICOM store that is being created. Any string value up to 256 characters in length.
dicom_store

DicomStore

The DICOM store to create.

DeleteDicomStoreRequest

Deletes the specified DICOM store and removes all images that are contained within it.

Fields
name

string

Required. The resource name of the DICOM store to delete.

Authorization requires the following IAM permission on the specified resource name:

  • healthcare.dicomStores.delete

DicomStore

Represents a DICOM store.

Fields
name

string

Identifier. Resource name of the DICOM store, of the form projects/{project_id}/locations/{location_id}/datasets/{dataset_id}/dicomStores/{dicom_store_id}.
notification_config

NotificationConfig

Notification destination for new DICOM instances. Supplied by the client.
labels

map<string, string>

User-supplied key-value pairs used to organize DICOM stores.

Label keys must be between 1 and 63 characters long, have a UTF-8 encoding of maximum 128 bytes, and must conform to the following PCRE regular expression: [\p{Ll}\p{Lo}][\p{Ll}\p{Lo}\p{N}_-]{0,62}

Label values are optional, must be between 1 and 63 characters long, have a UTF-8 encoding of maximum 128 bytes, and must conform to the following PCRE regular expression: [\p{Ll}\p{Lo}\p{N}_-]{0,63}

No more than 64 labels can be associated with a given store.
stream_configs[]

StreamConfig

Optional. A list of streaming configs used to configure the destination of streaming exports for every DICOM instance insertion in this DICOM store. After a new config is added to stream_configs, DICOM instance insertions are streamed to the new destination. When a config is removed from stream_configs, the server stops streaming to that destination. Each config must contain a unique destination.

StreamConfig

StreamConfig specifies configuration for a streaming DICOM export.

Fields
Union field destination. Required. destination can be only one of the following:
bigquery_destination

BigQueryDestination

Results are appended to this table. The server creates a new table in the given BigQuery dataset if the specified table does not exist. To enable the Cloud Healthcare API to write to your BigQuery table, you must give the Cloud Healthcare API service account the bigquery.dataEditor role. The service account is: service-{PROJECT_NUMBER}@gcp-sa-healthcare.iam.gserviceaccount.com. The PROJECT_NUMBER identifies the project that the DICOM store resides in. To get the project number, go to the Cloud Console Dashboard. It is recommended to not have a custom schema in the destination table which could conflict with the schema created by the Cloud Healthcare API. Instance deletions are not applied to the destination table.

The destination's table schema will be automatically updated in case a new instance's data is incompatible with the current schema. The schema should not be updated manually as this can cause incompatibilies that cannot be resolved automatically. One resolution in this case is to delete the incompatible table and let the server recreate one, though the newly created table only contains data after the table recreation.

BigQuery imposes a 1 MB limit on streaming insert row size, therefore any instance that generates more than 1 MB of BigQuery data will not be streamed.

If an instance cannot be streamed to BigQuery, errors will be logged to Cloud Logging (see Viewing error logs in Cloud Logging).

DicomStoreMetrics

DicomStoreMetrics contains metrics describing a DICOM store.

Fields

ExportDicomDataRequest

Exports data from the specified DICOM store. If a given resource, such as a DICOM object with the same SOPInstance UID, already exists in the output, it is overwritten with the version in the source dataset. Exported DICOM data persists when the DICOM store from which it was exported is deleted.

Fields
name

string

Required. The DICOM store resource name from which to export the data. For example, projects/{project_id}/locations/{location_id}/datasets/{dataset_id}/dicomStores/{dicom_store_id}.

Authorization requires the following IAM permission on the specified resource name:

  • healthcare.dicomStores.export

Union field destination. Specifies the destination of the output.

To enable the Cloud Healthcare API to write to resources in your project, such as Cloud Storage buckets, you must give the Cloud Healthcare API service account the proper permissions. The service account is: service-{PROJECT_NUMBER}@gcp-sa-healthcare.iam.gserviceaccount.com. The PROJECT_NUMBER identifies the project that the DICOM store resides in. To get the project number, go to the Cloud Console Dashboard. destination can be only one of the following:
gcs_destination

GcsDestination

The Cloud Storage output destination.

The Cloud Healthcare Service Agent requires the roles/storage.objectAdmin Cloud IAM roles on the Cloud Storage location.
bigquery_destination

BigQueryDestination

Fields
uri_prefix

string

The Cloud Storage destination to export to.

URI for a Cloud Storage directory where the server writes the result files, in the format gs://{bucket-id}/{path/to/destination/dir}). If there is no trailing slash, the service appends one when composing the object path. The user is responsible for creating the Cloud Storage bucket referenced in uri_prefix.
mime_type

string

MIME types supported by DICOM spec. Each file is written in the following format: .../{study_id}/{series_id}/{instance_id}[/{frame_number}].{extension} The frame_number component exists only for multi-frame instances.

Supported MIME types are consistent with supported formats in DICOMweb: https://cloud.google.com/healthcare/docs/dicom#retrieve_transaction. Specifically, the following are supported:

  • application/dicom; transfer-syntax=1.2.840.10008.1.2.1 (uncompressed DICOM)
  • application/dicom; transfer-syntax=1.2.840.10008.1.2.4.50 (DICOM with embedded JPEG Baseline)
  • application/dicom; transfer-syntax=1.2.840.10008.1.2.4.90 (DICOM with embedded JPEG 2000 Lossless Only)
  • application/dicom; transfer-syntax=1.2.840.10008.1.2.4.91 (DICOM with embedded JPEG 2000)
  • application/dicom; transfer-syntax=* (DICOM with no transcoding)
  • application/octet-stream; transfer-syntax=1.2.840.10008.1.2.1 (raw uncompressed PixelData)
  • application/octet-stream; transfer-syntax=* (raw PixelData in whatever format it was uploaded in)
  • image/jpeg; transfer-syntax=1.2.840.10008.1.2.4.50 (Consumer JPEG)
  • image/png

The following extensions are used for output files:

  • application/dicom -> .dcm
  • image/jpeg -> .jpg
  • image/png -> .png
  • application/octet-stream -> no extension

If unspecified, the instances are exported in the original DICOM format they were uploaded in.

GcsSource

Specifies the configuration for importing data from Cloud Storage.

Fields
uri

string

Points to a Cloud Storage URI containing file(s) with content only.

The URI must be in the following format: gs://{bucket_id}/{object_id}. The URI can include wildcards in object_id and thus identify multiple files. Supported wildcards:

  • '*' to match 0 or more non-separator characters
  • '**' to match 0 or more characters (including separators). Must be used at the end of a path and with no other wildcards in the path. Can also be used with a file extension (such as .dcm), which imports all files with the extension in the specified directory and its sub-directories. For example, gs://my-bucket/my-directory/**.dcm imports all files with .dcm extensions in my-directory/ and its sub-directories.
  • '?' to match 1 character.

All other URI formats are invalid. Files matching the wildcard are expected to contain content only, no metadata.

GetDicomStoreMetricsRequest

GetDicomStoreMetricsRequest specifices the DICOM store to get metrics for.

Fields
name

string

Required. The resource name of the DICOM store to get metrics for.

Authorization requires the following IAM permission on the specified resource name:

Fields
name

string

Required. The name of the DICOM store resource into which the data is imported. For example, projects/{project_id}/locations/{location_id}/datasets/{dataset_id}/dicomStores/{dicom_store_id}.

Authorization requires the following IAM permission on the specified resource name:

  • healthcare.dicomStores.import

Union field source. Specifies the source data location and import configuration.

To enable the Cloud Healthcare API to read from resources in your project such as Cloud Storage, you must give the Cloud Healthcare API service account the proper permissions. The service account is: service-{PROJECT_NUMBER}@gcp-sa-healthcare.iam.gserviceaccount.com. The PROJECT_NUMBER identifies the project that the DICOM store resides in. To get the project number, go to the Cloud Console Dashboard. source can be only one of the following:
gcs_source

GcsSource

Cloud Storage source data location and import configuration.

The Cloud Healthcare Service Agent requires the roles/storage.objectViewer Cloud IAM roles on the Cloud Storage location.

ImportDicomDataResponse

ListDicomStoresRequest

Lists the DICOM stores in the given dataset.

Fields
parent

string

Required. Name of the dataset.

Authorization requires the following IAM permission on the specified resource parent:

  • healthcare.dicomStores.list
page_size

int32

Limit on the number of DICOM stores to return in a single response. If not specified, 100 is used. May not be larger than 1000.
page_token

string

The next_page_token value returned from the previous List request, if any.
filter

string

Restricts stores returned to those matching a filter. The following syntax is available:

  • A string field value can be written as text inside quotation marks, for example "query text". The only valid relational operation for text fields is equality (=), where text is searched within the field, rather than having the field be equal to the text. For example, "Comment = great" returns messages with great in the comment field.
  • A number field value can be written as an integer, a decimal, or an exponential. The valid relational operators for number fields are the equality operator (=), along with the less than/greater than operators (<, <=, >, >=). Note that there is no inequality (!=) operator. You can prepend the NOT operator to an expression to negate it.
  • A date field value must be written in yyyy-mm-dd form. Fields with date and time use the RFC3339 time format. Leading zeros are required for one-digit months and days. The valid relational operators for date fields are the equality operator (=) , along with the less than/greater than operators (<, <=, >, >=). Note that there is no inequality (!=) operator. You can prepend the NOT operator to an expression to negate it.
  • Multiple field query expressions can be combined in one query by adding AND or OR operators between the expressions. If a boolean operator appears within a quoted string, it is not treated as special, it's just another part of the character string to be matched. You can prepend the NOT operator to an expression to negate it.

Only filtering on labels is supported. For example, labels.key=value.

ListDicomStoresResponse

Lists the DICOM stores in the given dataset.

Fields
dicom_stores[]

DicomStore
