[Augmented reality in echocardiography. A new method of computer-assisted training and image processing using virtual...

Area of Science:

• Medical imaging
• Augmented reality applications
• Cardiovascular imaging

Background:

• Augmented reality (AR) enhances medical education and 3D image data interpretation.
• Simulators are crucial for training complex or high-cost medical procedures.
• Echocardiography, particularly 3D datasets, presents challenges in spatial understanding for trainees.

Purpose of the Study:

• To introduce EchoCom2, an AR application for echocardiography training and 3D data exploration.
• To improve spatial comprehension of cardiac anatomy for echocardiography trainees.
• To facilitate the interpretation of complex 3D echocardiographic datasets.

Main Methods:

• Developed EchoCom2, linking a 3D heart model with echocardiographic volume data.
• Registered 3D echocardiographic data with the heart model for synchronized spatial and temporal orientation.
• Utilized an electromagnetic orientation and position system (EPOS) for interactive exploration and real-time feedback.

Main Results:

• EchoCom2 functions as a simulator for 2D echocardiographic examinations.
• It serves as an orientation and navigation aid for exploring 3D echocardiographic datasets.
• Simultaneous visualization of the cutting plane in both data and model aids in recognizing position and structures.

Conclusions:

• EchoCom2 effectively aids echocardiography trainees in developing 3D spatial understanding.
• The AR application improves the interpretation of 3D echocardiographic data by providing real-time spatial context.
• EchoCom2 offers a valuable tool for both educational and clinical applications in echocardiography.
