FHIR Resource Sanitizer Operator #

Authors: Holoscan SDK Team (NVIDIA)
Supported platforms: x86_64, aarch64
Language: Python
Last modified: June 28, 2025
Latest version: 1.1
Minimum Holoscan SDK version: 2.0.0
Tested Holoscan SDK versions: 2.5.0, 3.3.0
Contribution metric: Level 2 - Trusted

A Holoscan operator that processes and sanitizes FHIR medical records into a standardized, AI-friendly format while maintaining essential medical information.

Overview#

The FHIR Resource Sanitizer Operator is designed to transform raw FHIR (Fast Healthcare Interoperability Resources) medical records into a more standardized format suitable for AI processing. It handles various FHIR resource types including Patient, Observation, Condition, DiagnosticReport, ImagingStudy, and more, while implementing robust error handling and logging mechanisms.

Requirements#

holoscan
fhir.resources
pydantic

Example Usage#

Please check fhir_client.py in Generative AI Application on Holoscan integrating with FHIR Services.

Name Input/Output#

Input: records: A FHIRQueryResponse object containing patient medical records
Output: out: A sanitized FHIRQueryResponse object with standardized medical records

Parameters#

fhir_endpoint (str): FHIR service endpoint URL (default: "http://localhost:8080/")
