DICOM storage and transport
Stay organized with collections

HAI-DEF endpoints that deal with DICOM imaging, such as
Path Foundation
and
CXR Foundation,
are capable of retrieving their input data from
DICOM storage
systems that meet the following requirements:
DICOM standard storage
HAI-DEF endpoints require DICOM imaging to conform to the
DICOM standard. This includes defining all
required
Type-1 tags
and ensuring that tag values comply with their specified
Value Representation (VR)
and
Value Multiplicity (VM)
codes.
DICOMweb transport protocol
HAI-DEF endpoints require the DICOM storage system holding the imaging to
support the DICOMweb REST API
and more specifically JSON formatted
QIDO-RS and
WADO-RS
over HTTPS protocol.
The Uniform Resource Identifiers (URIs) must end with a valid DICOMweb suffix:
for example the URI for a
DICOM series
must end with a studies/${STUDY-UID}/series/${SERIES-UID} suffix.
Transfer syntax transcoding
HAI-DEF endpoints transcode their DIOCM inputs based on the
Transfer Syntax UID.
Refer to the respective serving API specification for details.
Private network accessibility
HAI-DEF endpoints operate within the secure Google Cloud private network as
Vertex AI prediction endpoints.
Therefore, if you plan to use HAI-DEF endpoints with DICOMWeb data links, the
DICOMWeb store has to be accessible from this private network. Refer to
Google Cloud private access options.
Authentication and authorization
The DICOMweb storage system either must support public access or accept
OAuth 2.0 bearer tokens for
authorization.
