GCP data access

You can get the NIH chest x-ray images from Cloud Storage, BigQuery, or using the Cloud Healthcare API.

Cloud Storage

The NIH chest x-ray data is available in the following Cloud Storage bucket:

gs://gcs-public-data--healthcare-nih-chest-xray

Go to the NIH chest x-ray dataset in Cloud Storage

The bucket includes paths to the original PNG files, as well as to DICOM instances:

gs://gcs-public-data--healthcare-nih-chest-xray/png/FILENAME.png

DICOM (provided by Google):

gs://gcs-public-data--healthcare-nih-chest-xray/dicom/FILENAME.dcm

The Cloud Storage bucket uses the "Requester Pays" model for billing. Your GCP project will be billed for the charges associated with accessing the NIH data. For more information, see Requester Pays.

BigQuery

The NIH chest x-ray data is available in the chc-nih-chest-xray GCP project in BigQuery.

Go to the NIH chest x-ray dataset in BigQuery
