Kinect2 - respiratory movement detection study.

Area of Science:

• Medical Physics
• Radiotherapy Technology
• Image-guided Therapy

Background:

• Accurate patient positioning is critical in radiotherapy to target tumors while sparing healthy tissues.
• Current positioning methods, including skin markers and X-ray imaging, have limitations in accuracy and invasiveness.
• Existing commercial systems utilize Time of Flight cameras for real-time motion monitoring.

Purpose of the Study:

• To assess the feasibility of using the Microsoft Kinect2 camera for patient positioning in radiotherapy.
• To evaluate the Kinect2 camera's capability for real-time patient movement monitoring and respiration gating.
• To explore a cost-effective, non-invasive alternative for radiotherapy patient alignment.

Main Methods:

• The Microsoft Kinect2 Time of Flight camera was tested for its performance in patient positioning tasks.
• The study focused on evaluating the camera's ability to track patient movement during simulated radiotherapy sessions.
• Respiration data acquisition and analysis were performed using the Kinect2 camera.

Main Results:

• The Kinect2 camera demonstrated potential for non-invasive patient positioning in radiotherapy.
• Real-time monitoring of patient movement was achievable with the tested system.
• Preliminary results suggest suitability for respiration gating applications.

Conclusions:

• The Microsoft Kinect2 camera presents a promising, low-cost solution for enhancing patient positioning accuracy in radiotherapy.
• Its non-invasive nature and real-time capabilities could facilitate clinical adoption.
• Further validation is warranted to fully integrate this technology into radiotherapy workflows.
