Digital twin creation of a proton therapy treatment environment with hybrid LiDAR and RGB 3D camera.

ABSTRACT:

Introduction

This study evaluates the feasibility of utilizing a commercial-grade 3D LiDAR/RGB camera, combined with 3D reconstruction software, to create an accurate and hyper-realistic digital model of a proton therapy treatment room. This reconstructed model aims to enhance collision avoidance strategies and improve 3D machine model accessibility. Utilization of a 3D LiDAR/RGB camera as a radiotherapy environment modeling has not been reported prior.

Methods

To create a comprehensive 3D model of a half-gantry proton therapy system, colored point cloud data was captured using the Matterport Pro 3 camera, a hybrid LiDAR and RGB imaging system with high-resolution capabilities (134.2 MP), a 360° horizontal field of view, and 20 mm accuracy at 10 m. A total of 117 acquisition
