## [Introduction] Anandi: Multimodal AI Empowers Automated Fetal Biometry and Intelligent Decision Support

Anandi is an intelligent auxiliary system for prenatal medical examinations, integrating technologies such as the DETR computer vision model, fine-tuned Gemma large language model, LangGraph state management, and RAG (Retrieval-Augmented Generation) with LanceDB vector database. Its core functions are automatic biometric measurement of fetal ultrasound images and intelligent filling of PC-PNDT Form F, aiming to improve efficiency and accuracy, reduce the burden on medical staff, and ensure compliance.

## [Background] Clinical Pain Points and Compliance Requirements of Prenatal Diagnosis

Traditional fetal biometry relies on manual operation of ultrasound equipment for readings, which is time-consuming and prone to errors; Indian law requires prenatal diagnosis institutions to submit PC-PNDT Form F, and manual filling is cumbersome, easy to miss errors, and has compliance risks.

## [Technical Approach] Analysis of Multimodal AI Architecture and Key Components

- Computer Vision: Based on the DETR end-to-end object detection model, no anchor boxes or non-maximum suppression required, directly analyzing ultrasound images to extract measurement data;
- NLP: Using a fine-tuned Gemma 4B model to understand medical terminology and clinical context;
- State Management: Coordinating component interactions via LangGraph to manage the complete process from image input to report generation;
- Knowledge Enhancement: RAG architecture combined with LanceDB vector database to retrieve external knowledge such as medical literature/guidelines to overcome model hallucinations;
- System Design: Frontend-backend separation architecture, where the backend handles AI inference and business logic, and the frontend processes user interactions.

## [Application Scenarios and Resources] Clinical Value and Demo Environment

- Clinical Value: Automatic biometry improves examination efficiency and accuracy; intelligent filling of PC-PNDT forms ensures document completeness and standardization;
- Resource Support: An online demo environment is provided (anandi-ai.vercel.app), developed using Python for easy understanding and contribution by developers.

## [Conclusion and Insights] Technology Integration and Practical Orientation of Medical AI

Anandi is a typical paradigm of medical AI application in vertical fields, demonstrating the idea of organically integrating multiple technologies to solve clinical problems; the technology selection (DETR/Gemma/LangGraph/LanceDB) has reference value; the balance between technological advancement, compliance, and practicality, as well as the user-centric design concept, are worthy of recognition.
