<a name="dicomweb-search-series"></a>

Use the `SearchDICOMSeries` API to search for DICOM series in a HealthImaging [data store](getting-started-concepts.md#concept-data-store). You can search for DICOM series in HealthImaging by constructing a URL that includes supported DICOM data elements (attributes). Series search results are returned in JSON format, ordered by ascending (oldest to latest).

**To search for DICOM series**  


1. Collect HealthImaging `region` and `datastoreId` values. For more information, see [Getting data store properties](get-data-store.md).

1. Collect the `StudyInstanceUID` value. For more information, see [Getting image set metadata](get-image-set-metadata.md).

[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/healthimaging/latest/devguide/dicomweb-search-series.html)

1. Prepare and send your request. `SearchDICOMSeries` uses a HTTP GET request with [AWS Signature Version 4](https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_sigv.html) signing protocol. The following example uses the `curl` command line tool to search for DICOM series information.

------
#### [ curl ]

   ```
   curl --request GET \
     "https://dicom-medical-imaging.us-east-1.amazonaws.com/datastore/datastoreId/studies/StudyInstanceUID/series[?query]"
     --aws-sigv4 'aws:amz:us-east-1:medical-imaging' \
     --user "$AWS_ACCESS_KEY_ID:$AWS_SECRET_ACCESS_KEY" \
     --header "x-amz-security-token:$AWS_SESSION_TOKEN" \
     --header 'Accept: application/dicom+json' \
     --output results.json
   ```

   Series search results are returned in JSON format, ordered by `Series Number (0020,0011)` in ascending order (oldest to latest).
