MedViT - Medical Vision Transformer
1. Introduction
MedViT is a state-of-the-art Vision Transformer specifically designed for medical image analysis. This latest version incorporates advanced attention mechanisms optimized for detecting subtle anomalies in medical imagery. The model has been trained on a diverse dataset spanning multiple imaging modalities including X-ray, CT, MRI, and pathology slides.
Compared to the previous version, MedViT shows remarkable improvements in detecting early-stage conditions. For instance, in the ChestX-ray14 benchmark, the model's AUC has increased from 0.82 in the previous version to 0.91 in the current version. This advancement stems from the multi-scale patch embedding mechanism that captures both fine-grained cellular details and broader anatomical structures.
Beyond improved detection capabilities, this version also offers enhanced interpretability through attention visualization and reduced false positive rates for clinical deployment.

3. Clinical Integration & API Platform
We offer a secure API for integrating MedViT into clinical workflows. All endpoints are HIPAA-compliant and support DICOM format inputs. Please check our official documentation for more details.
4. How to Run Locally
Please refer to our code repository for more information about running MedViT locally.
Key requirements for deployment:
- GPU with at least 16GB VRAM recommended for full-resolution analysis
- Support for DICOM, NIfTI, and standard image formats
- Optional integration with PACS systems
Input Preprocessing
We recommend the following preprocessing pipeline:
preprocessing = {
"resize": (384, 384),
"normalize": {"mean": [0.485, 0.456, 0.406], "std": [0.229, 0.224, 0.225]},
"intensity_windowing": True # For CT/MRI
}
Inference Configuration
For optimal results, use these inference settings:
inference_config = {
"batch_size": 8,
"use_tta": True, # Test-time augmentation
"threshold": 0.5,
"return_attention_maps": False
}
Multi-Modal Analysis
For multi-modal studies, combine predictions using:
multi_modal_config = {
"fusion_method": "attention_weighted",
"modalities": ["ct", "mri", "pet"],
"weight_by_confidence": True
}
