Area of Science:

Medical Physics
Radiotherapy Technology
Computer Vision

Background:

Accurate monitoring of patients and equipment is crucial in radiotherapy.
Existing methods may lack comprehensive integration of diverse data sources.
The need for enhanced real-time verification in radiation delivery is recognized.

Purpose of the Study:

To develop and evaluate a method for monitoring radiotherapy environments.
To create a precise virtual environment integrating treatment plans and real-world data.
To enable external video-based control for improved radiotherapy procedures.

Main Methods:

Integrating treatment plan data with visual, geometric, and semantic information.
Generating a high-precision virtual environment of the radiotherapy scene.
Utilizing multi-camera video sequences to compare real-world data with the virtual model.
Employing fuzzy logic and scene element features for analysis.

Main Results:

A method for creating a precise virtual representation of the radiotherapy setting was established.
The approach allows for the confrontation of filmed scene information with its numerical model.
Feasibility is currently being quantitatively evaluated in a non-treatment setting.

Conclusions:

The proposed method shows potential for enhancing radiotherapy monitoring and safety.
Further development aims to integrate this into a real-time, video-based external control module.
This technology could lead to improved precision and verification in radiation therapy delivery.
