Description

Upon a user-initiated request to perform a severity analysis on an ingested scalp image, the system shall execute the Automatic Severity of Alopecia Tool (ASALT) assessment. The system shall perform the following integrated actions:

1. Calculate clinical signs: Invoke the ASALT model to analyze the image and compute the percentage of scalp hair loss, which constitutes the final, composite SALT score.
2. Generate visual evidence: Create a derivative image by overlaying a hair loss mask on the original input image. This mask shall visually delineate the areas of alopecia identified by the model.
3. 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 SALT score (percentage of hair loss) and its corresponding clinical interpretation band (e.g., "Moderate").
   • The visual evidence image generated in step 2.

Derived from PRS

• PRS-2ZB: Measure severity by combining image analysis and user-reported symptoms in scoring systems
