Summary of Generative AI in Biomedical Video Synthesis
Generative AI models, particularly Diffusion Models (DMs) and Generative Adversarial Networks (GANs), offer transformative potential in healthcare. DMs have shown superior performance in generating high-quality, temporally consistent biomedical videos, addressing challenges like data scarcity and the need for diverse training data for diagnostic algorithms. GANs, while effective, often face issues with training stability and mode collapse.
This review highlights the critical need for advanced models that can maintain temporal consistency, improve computational efficiency, and overcome data limitations to truly revolutionize personalized medicine and connected healthcare.
Diffusion Models: Superior Fidelity and Control
Diffusion Models (DMs) excel in generating realistic medical videos, offering high-fidelity samples with better diversity and controllability than GANs. Their probabilistic denoising approach ensures stable training and is particularly suited for complex, high-resolution medical video synthesis.
Key Strengths: Exceptional image quality, temporal consistency, and robust training. DMs are becoming the preferred method for generating synthetic echocardiograms and surgical videos, providing a valuable resource for training AI algorithms and simulating clinical scenarios.
Generative Adversarial Networks: Speed and Flexibility
Generative Adversarial Networks (GANs) have demonstrated impressive results in medical image generation and can synthesize videos in a single forward pass, making them computationally efficient for real-time applications. Various GAN architectures, including conditional GANs and StyleGANs, have been adapted for medical video synthesis.
Key Strengths: Faster inference times and flexibility in controlling specific features. However, GANs often struggle with temporal consistency and can suffer from training instabilities like mode collapse, limiting diversity in outputs.
Challenges and Mitigation Strategies
Despite their promise, generative models face several challenges in medical video synthesis:
- Data Scarcity: Limited access to large, diverse, and well-annotated medical video datasets. Mitigation involves data augmentation, transfer learning, and generating synthetic data.
- Temporal Consistency: Ensuring smooth and realistic motion across video frames. Recurrent GANs and temporal-aware DMs are being explored.
- Computational Cost: High computational demands for training and inference, especially for DMs. Lightweight architectures and mixed-precision training can help.
- Generalizability: Models often struggle to generalize across different imaging modalities or patient populations. Domain adaptation and multimodal approaches are key.
- Control & Interpretability: Fine-tuning outputs to specific clinical features remains complex. Latent space manipulation and auxiliary classifiers offer solutions.
Real-World Clinical Applications
Generative AI in biomedical video synthesis offers a myriad of applications:
- Enhanced Diagnostics: Improved algorithms for disease detection and diagnosis through enriched training data.
- Surgical Training: Realistic simulation of complex surgical procedures and disease progression for educational purposes.
- Personalized Medicine: Generating patient-specific video data to simulate treatment outcomes and optimize planning.
- Reduced Radiation Exposure: Synthesizing missing frames or generating low-dose images from limited inputs, as seen in DSA imaging.
- Privacy Preservation: Creating synthetic data reduces reliance on sensitive patient data, enhancing privacy in research and development.

Case Study: Endora for Endoscopy Simulation
Challenge: Generating realistic clinical endoscopy videos to enhance surgical AI algorithms and robotic systems, specifically addressing spatio-temporal complexities.
Solution: Endora, a video Diffusion Model, integrated a latent DM with a video transformer architecture, guided by a 2D foundation model (DINO). It was trained on Colonoscopic, Kvasir-Capsule, and Cholec-Triplet datasets.
Result: Endora outperformed existing GANs and LVDMs in generating higher-quality endoscopic videos across FVD, FID, and IS metrics. It successfully reconstructed 3D scenes with realistic structures, proving its potential for surgical simulations, despite low resolution outputs.
