MVis-Fold: A Three-Dimensional Microvascular Structure Inference Model for Super-Resolution Ultrasound
🤖 AI Summary
This study addresses the challenge of three-dimensional (3D) microvascular reconstruction from super-resolution ultrasound (SRUS) imaging, which has traditionally been limited to two-dimensional (2D) representations. To overcome this limitation, the authors propose MVis-Fold, a novel model that enables high-fidelity 3D reconstruction of microvascular networks directly from 2D SRUS images for the first time. The method employs a cross-scale neural network architecture that deeply integrates deep learning with SRUS imaging physics to accurately infer 3D structural parameters inaccessible to conventional 2D approaches. Experimental validation on solid tumor datasets demonstrates the model’s accuracy and reliability, offering a powerful new tool for quantitative 3D microvascular analysis and potential applications in disease diagnosis.
📝 Abstract
Super-resolution ultrasound (SRUS) technology has overcome the resolution limitations of conventional ultrasound, enabling micrometer-scale imaging of microvasculature. However, due to the nature of imaging principles, three-dimensional reconstruction of microvasculature from SRUS remains an open challenge. We developed microvascular visualization fold (MVis-Fold), an innovative three-dimensional microvascular reconstruction model that integrates a cross-scale network architecture. This model can perform high-fidelity inference and reconstruction of three-dimensional microvascular networks from two-dimensional SRUS images. It precisely calculates key parameters in three-dimensional space that traditional two-dimensional SRUS cannot readily obtain. We validated the model's accuracy and reliability in three-dimensional microvascular reconstruction of solid tumors. This study establishes a foundation for three-dimensional quantitative analysis of microvasculature. It provides new tools and methods for diagnosis and monitoring of various diseases.
