Description​
Upon a user-initiated request to perform a severity analysis on an ingested image, the system shall execute the Automatic SCORAD (ASCORAD) assessment. The system shall perform the following integrated actions:
- Calculate clinical signs: Invoke the ASCORAD model to compute clinical signs from the image and combine them with user-provided subjective symptom scores to calculate:
- Visual signs (from image analysis): The quantitative grades for Erythema, Swelling, Crusting, Excoriation, Lichenification, and Dryness, as well as the percentage of Affected Surface Area.
- Subjective symptoms (from user input): The system shall incorporate the provided values for Pruritus and Sleeplessness into the final score calculation.
- Compute SCORAD score and its corresponding interpretation using the calculated clinical scores.
- Generate visual evidence: Create a derivative image by overlaying a segmentation mask on the original input image. This mask shall precisely delineate the lesion areas used for the surface area calculation.
- 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 SCORAD score and its corresponding clinical interpretation band (e.g., "Mild," "Moderate," "Severe").
- All objective and subjective component values used in the calculation.
- The visual evidence image generated in step 2.
