Cross-Community Access for Imaging

Summary

Cross-Community Access for Imaging(XCA) - Supports the means to query and retrieve patient relevant medical imaging data held by other communities.

The XCA-I Profile extends the IT Infrastructure XCA Profile. XCA provides access to all medical data including diagnostic reports and imaging manifests. XCA-I provides access to the images referenced in the imaging manifests.

Benefits

• Image access between Communities
• Common health information infrastructure with non-imaging data

Details

The Cross-Community Access for Imaging profile supports the means to query and retrieve patient relevant medical image data held by other communities. A community is defined as a coupling of facilities/enterprises that have agreed to work together using a common set of policies for the purpose of sharing clinical information via an established mechanism. Facilities/enterprises may host any type of healthcare application such as EHR, PHR, etc.

Such communities may be XDS Affinity Domains which define image sharing using the XDS-I profile. This profile addresses sharing between such communities.

The XCA-I Profile extends the IT Infrastructure XCA Profile for Imaging. XCA provides access to Diagnostic reports and Imaging Manifests. XCA-I provides access to the imaging objects referenced in the Manifests.
