Description

Upon a user-initiated request to perform a severity analysis on an ingested image, the system shall execute the Automatic International Hidradenitis Suppurativa Severity Score System (AIHS4) assessment. The system shall perform the following integrated actions:

1. Calculate clinical signs: Invoke the AIHS4 model to detect and count the total number of nodules, abscesses and tunnels in the image.
2. Compute IHS4 score and its corresponding interpretation using the calculated clinical scores.
3. Generate visual evidence: Create an annotated image by overlaying bounding boxes on the original input image. These boxes shall highlight each individual lesion detected. The annotations shall be visually differentiated by lesion type (e.g., using different colors or labels for nodules, abscesses, and draining tunnels).
4. Assemble and present report: Generate and display a structured clinical report that consolidates the analysis results. The report shall contain the following clearly labelled data points:
   • The final IHS4 score and its corresponding clinical interpretation band (e.g., "Mild," "Moderate," "Severe").
   • The counts for each lesion type: nodules, abscesses, and draining tunnels.
   • The annotated visual evidence image generated in step 2.
