+**Pipeline Multi-Agents pour l'analyse de comptes rendus radiologiques**  
+I3AFD 2026 — Groupe 4 — BioMistral-7B (quantize 4-bit)
+

+
+## 🚀 Fonctionnalités
+
+| Fonctionnalité | Description |
+|---|---|
+| 🏠 **Tableau de bord** | Métriques, pipeline 7 agents, graphiques évolution/radar |
+| 🔬 **Analyser** | Texte libre + PDF/Word/Image + base de données |
+| 📊 **Performance** | Ablation study, tableau métriques, courbe évolution ROUGE-L |
+| 🗄️ **Base de données** | 5 rapports démo IU X-Ray + ajout dynamique |
+| 🕒 **Historique** | Toutes les analyses avec filtrage par date |
+| ⚙️ **Paramètres** | **Activation/désactivation des agents** + reset base |
+| 📄 **Export PDF** | Rapport complet téléchargeable |
+| 🖨️ **Export HTML** | Synthèse médecin + synthèse patient imprimables |
+| 🌐 **Bilingue** | Français / Anglais avec traduction automatique |
+| 🤖 **7 Agents** | Détecteur, Extracteur, Structurateur, Vérificateur, Méd.Synth, Pat.Synth, Monolithique |
+
+---
+
+## 🤖 Contrôle des Agents (NOUVEAU)
+
+Dans l'onglet **⚙️ Paramètres**, vous pouvez activer ou désactiver chaque agent individuellement :
+
+- 🔍 **Agent 1 — Détecteur** : Valide que le document est un rapport médical
+- ⚡ **Agent 2 — Extracteur** : Extrait les entités cliniques (anatomie, findings, anomalies)
+- 🗂️ **Agent 3 — Structurateur** : Structure les données en JSON
+- 🛡️ **Agent 4 — Vérificateur** : Évalue la fidélité et la complétude
+- 🩺 **Agent 5 — Synthèse Médicale** : Génère le rapport pour le médecin
+- 👤 **Agent 6 — Synthèse Patient** : Génère l'explication pour le patient
+- ⚖️ **Agent 7 — Monolithique** : Baseline pour comparaison de performance
+
+> Un agent désactivé est sauté dans le pipeline et retourne un résultat par défaut. Le pipeline continue normalement avec les agents restants.
+
+---
+
+## 🛠️ Architecture
+
+```
+Rapport radiologique
+       ↓
+[Agent 1] Détecteur      → Validation médicale
+       ↓
+[Agent 2] Extracteur     → Entités cliniques (LLM)
+       ↓
+[Agent 3] Structurateur  → Structuration JSON (LLM)
+       ↓
+[Agent 4] Vérificateur   → Fidélité & qualité
+       ↓
+[Agent 5] Méd. Synth.   → Synthèse médicale (LLM)
+       ↓
+[Agent 6] Pat. Synth.   → Synthèse patient (LLM)
+       ↓
+[Agent 7] Monolithique  → Baseline comparaison (LLM)
+       ↓
+Métriques ROUGE-L + BERTScore
+```
+
+---
+
+## 📋 Utilisation
+
+1. Allez dans **🔬 Analyser**
+2. Collez un rapport radiologique ou importez un fichier (PDF, Word, Image, TXT)
+3. Choisissez la langue (Français / English)
+4. Cliquez sur **🚀 Lancer l'analyse**
+5. Téléchargez le rapport PDF ou les synthèses HTML
+
+**Pour gérer les agents :**  
+Allez dans **⚙️ Paramètres** → section "Contrôle des Agents" → cochez/décochez les agents souhaités
+
+---
+
+## ⚙️ Notes techniques
+
+- **Modèle** : BioMistral-7B si GPU disponible, TinyLlama-1.1B-Chat sinon (CPU)
+- **Dataset** : IU X-Ray (Indiana University Chest X-Ray Collection)
+- **Évaluation** : ROUGE-L, BERTScore F1, Fidélité clinique
+- **Traduction** : Deep Translator (Google Translate API)
