+## 1. Introduction
+
+MedVisionAI represents a breakthrough in medical imaging analysis. In this latest version, MedVisionAI has achieved significant improvements in diagnostic accuracy and multi-modal imaging interpretation through advanced transfer learning and domain-specific fine-tuning. The model demonstrates exceptional performance across radiology, pathology, and dermatology imaging benchmarks, approaching human-expert level performance in many categories.

+</p>
+
+Compared to the previous version, the upgraded model shows remarkable improvements in detecting subtle abnormalities. For instance, in the RadBench-2025 evaluation, the model's tumor detection sensitivity increased from 82% in the previous version to 94.3% in the current version. This advancement stems from enhanced attention mechanisms during the diagnostic reasoning process: the previous model processed images in 2K token context windows, whereas the new version utilizes 8K token context for comprehensive analysis.
+
+Beyond its improved diagnostic capabilities, this version also offers reduced false-positive rates and enhanced support for multi-modal inputs combining imaging with clinical notes.

+### Overall Performance Summary
+MedVisionAI demonstrates exceptional performance across all evaluated medical imaging benchmark categories, with particularly notable results in detection and safety-critical tasks.
+
+## 3. Clinical Integration & API Platform
+We offer HIPAA-compliant API endpoints and clinical integration services. Please check our official website for compliance documentation and integration guides.
+
+## 4. How to Run Locally
+
+Please refer to our clinical deployment repository for information about running MedVisionAI in healthcare environments.
+
+Compared to previous versions, the deployment recommendations for MedVisionAI have the following changes:
+
+1. GPU with minimum 24GB VRAM is recommended for optimal inference speed.
+2. Multi-image batch processing is now supported for radiology workflows.
+
+The model architecture of MedVisionAI-Lite is optimized for edge deployment while maintaining diagnostic accuracy above 95% of the full model.
+
+### System Configuration
+We recommend using the following clinical context prompt:
+```
+You are MedVisionAI, an AI assistant for medical imaging analysis.
+Current examination date: {exam_date}
+Patient context: {patient_context}
+```
+
+### Confidence Thresholds
+We recommend setting the diagnostic confidence threshold to 0.85 for clinical alerts.
+
+### Input Formats
+For DICOM image analysis, use the following template:
+```
+image_template = \
+"""[modality]: {modality}
+[body_region]: {body_region}
+[clinical_indication]: {indication}
+[image_data_begin]
+{encoded_image}
+[image_data_end]
+{diagnostic_question}"""
+```
