SRS-028: Orchestrate diagnosis support workflow

Identifier

SRS-016

Software System

• Orchestrator

Category

• Functional

Description

Upon receiving a diagnosis support request via the API, the system shall orchestrate the end-to-end processing workflow. The system shall perform the following integrated actions:

1. Parse request: The system shall parse the incoming request to extract the set of one or more dermatological images.
2. Invoke processors: The system shall sequentially invoke the required processors to handle the request.
   • First, it shall execute pre-processing processors responsible for image adequacy assessment (PRS-003) and input validation (PRS-004).
   • Upon successful pre-processing, it shall call the appropriate AI analysis processor to generate the probability distributions and explainability heat maps.
3. Aggregate data: The system shall aggregate the results returned from the AI analysis processor, which includes both the aggregated probabilities and the per-image analyses.
4. Invoke report builder: The system shall pass the aggregated data to the Report Builder microservice to assemble the final, structured clinical report as defined in software requirements SRS-013, SRS-014, and SRS-015.
5. Return response: The system shall return the final, structured report.
