【Introduction】
Medical imaging plays a crucial role in modern healthcare, indispensable from diagnosis and surgical planning to treatment monitoring, all relying on the precise visualization of internal human structures. H.I.T. (Health, Innovation, Technology)’s “3D Imaging SAM and Generation Technology Exchange Group” is dedicated to overcoming the limitations of traditional 2D imaging by leveraging cutting-edge Segment Anything Models (SAM) and 3D generation technologies. We aim to usher medical imaging into a new era of three-dimensional interaction. Our goal is to provide more intuitive, precise, and intelligent 3D medical imaging solutions, completely transforming how doctors observe, understand, and interact with human anatomy.
I. Revolutionizing Medical Imaging from 2D to 3D, from Segmentation to Generation
H.I.T. has achieved exciting results in 3D medical imaging SAM and generation technology:
- Precise Segmentation in Medical Imaging with SAM (Segment Anything Model) :
- We actively explore and apply the potential of SAM and its variants for medical image segmentation. SAM can perform rapid and precise segmentation of any object in an image, demonstrating excellent generalization capabilities even with limited annotated data. This is highly significant for segmenting complex and diverse tissues, organs, and lesions in medical images.
- (Although the presentation doesn’t directly showcase SAM applications, SAM is a crucial prerequisite technology for accurate 3D reconstruction and analysis. The image report generation and dental 3D imaging on P.26 and P.31 rely on precise structural identification and segmentation of 2D images.)
- Visual Aid Suggestion: Use publicly available diagrams illustrating SAM’s ability to segment organs or lesions in medical images (like X-rays, CT scans) with its powerful “click-to-segment” or “box-to-segment” capabilities.
- Intelligent Generation of 3D Models from 2D Medical Images :
- We have successfully developed technology to intelligently generate high-precision 3D models from a series of 2D medical images (such as CT, MRI slices) or single 2D images (like X-rays, endoscopic photos).
- These 3D models are not just visual reconstructions; they contain rich anatomical information and allow for interactive operations such as rotation, scaling, and transparency, providing doctors with unprecedented observational perspectives.
- Visual Aid Suggestion: Showcase the generation of dental 3D models from X-ray images (Omniverse Kaolin APP). Demonstrates general image-to-3D technology. “Automated 3D Modeling from Medical Records Using Multiview Diffusion AI,” directly illustrates an advanced workflow for automatically generating 3D surgical models from medical records (including images).
- Text/Image-Guided 3D Medical Content Generation (Text-to-3D / Image-to-3D) :
- We are exploring the direct generation of corresponding 3D medical content using text descriptions (e.g., “generate a 3D liver model with a specific lesion”) or reference images. This technology holds immense potential in medical education, surgical simulation, and personalized implant design.
- Visual Aid Suggestion: Shows general examples of Text-to-3D (e.g., “a delicious hamburger”) and Image-to-3D (Zelda figurine). Shap-E and Point-E display more diverse text/image-to-3D generation effects. Text descriptions (Surgical Instruction Description) are one of the inputs for generating 3D surgical models.
- Application of Advanced Platforms like NVIDIA Omniverse Kaolin:
- We fully leverage advanced 3D development and collaboration platforms like NVIDIA Omniverse Kaolin APP to accelerate the creation, rendering, simulation, and deployment of 3D medical models. These platforms provide powerful toolsets and efficient rendering pipelines, ensuring the quality and real-time interactivity of the generated 3D models.
- Visual Aid Suggestion: Explicitly mention the application of Omniverse Kaolin APP in dental 3D imaging and surgical 3D modeling.
- Accelerating 3D Model Inference and Optimization :
- We utilize software like NVIDIA TensorRT to accelerate the inference process of 3D models, ensuring rapid generation and interaction with 3D models in clinical applications to meet real-time demands.
- Visual Aid Suggestion: NVIDIA TensorRT software accelerates inference time.
II. A More Realistic, Intelligent, and Interactive 3D Medical Vista
H.I.T.’s 3D Imaging SAM and Generation Technology will continue to explore the cutting edge, focusing on:
- Ultra-High-Precision 3D Digital Twins with Physiological Functions:
- Beyond morphological reconstruction, we aim to construct 3D Digital Twins capable of simulating physiological functions and pathological changes. Examples include simulating hemodynamics, drug distribution in the body, and tumor growth.
- (Reference to latest tech trends): Medical digital twins are a current research hotspot, requiring deep integration of multi-physics simulation and AI.
- Real-Time Intraoperative 3D Navigation and Augmented Reality (AR) Overlay:
- Register and fuse pre-operatively generated 3D models with real-time intraoperative images (such as endoscopy, ultrasound) to achieve precise intraoperative 3D navigation.
- Further overlay 3D anatomical structures and lesion information onto the surgical field or the surgeon’s AR glasses using augmented reality (AR), providing surgeons with “X-ray vision.”
- (Reference to latest tech trends): AR surgical navigation systems are rapidly developing, with high demands for registration accuracy and real-time performance.
- Interactive 3D Surgical Simulation and Skills Training Systems:
- Develop highly realistic 3D surgical simulators that allow medical students and young doctors to practice surgical procedures in a virtual environment and receive immediate feedback. This will greatly enhance the safety and efficiency of surgical skills training.
- (Reference to latest tech trends): VR/AR surgical simulators combined with haptic feedback technology can provide a more realistic experience.
- Automated Design of Personalized 3D-Printed Implants and Surgical Guides:
- Based on individual patient’s 3D imaging data, automatically design and optimize personalized 3D-printed implants (such as orthopedic implants, dental restorations) and surgical guides, achieving true precision medicine.
- (Reference to latest tech trends): AI-aided design combined with 3D printing is revolutionizing the manufacturing of personalized medical devices.
- Intelligent 3D Lesion Detection and Quantitative Analysis Fusing Multimodal Information:
- Combine SAM segmentation capabilities with 3D generation technology, and fuse information from different imaging modalities (e.g., CT+MRI+PET), to develop more intelligent tools for automated 3D lesion detection, segmentation, volume measurement, and malignancy assessment.
