Benchmarking trial begins for Computer Vision technique

Started benchmarking our Computer Vision patient alignment technique against the current gold standard IR-marker motion tracking.

Project Overview

Traditional surface-guided radiation therapy (SGRT) relies on fixed, expensive hardware with limited adaptability. Our approach replaces this with low-cost RGB cameras and neural networks, enabling real-time patient pose tracking and internal anatomy estimation from external surfaces.

Improved Access

Improves access to simulation-free treatment for ~50% of patients currently excluded

Reduced Clinic Visits

Leverages diagnostic CTs and video-based pose tracking to reduce clinic visits

Higher Precision

Models skeletal and soft tissue shifts using deformation models for higher precision

This innovation supports simulation-free workflows — eliminating the need for CT simulation in palliative treatment and reducing delays, burden, and cost.

This work builds on advanced computer vision techniques including SMPL-based modeling and pose estimation, applied in the context of real-world radiation oncology workflows.

Multi-View Demonstration

Simultaneous visualization of RGB, depth, pose tracking, and internal anatomy estimation

3D Point Cloud Visualization

Interactive 3D visualization for radiation therapy planning and analysis.
