Interactive 3D Models and Animations for Cardiac Imaging Education

Background

Cardiac imaging is a specialized branch of medical imaging that focuses on capturing detailed images of the heart. The coronary angiography procedure is one of the cardiac imaging techniques where radiographers use different angles and projections to get a comprehensive view of the coronary arteries in the heart and assess any potential blockages or abnormalities. Radiography student needs to grasp the theoretical and practical knowledge of these procedures before attending their clinical attachments and working in the field. However, the current teaching relies on static visualization (eg. still illustrations and photographs) which is insufficient to deliver the complex concepts in cardiac imaging. Practical sessions are challenging due to the limited access to the facility and involve ionizing radiation. Integrating 3D models and animations into e-learning for teaching cardiac imaging can significantly enhance the learning experience and provide an immersive and interactive environment.

Methods

3D models and animations were developed using Autodesk Maya software from creating 3D models to animations and rendering of coronary angiography procedures demonstrating different angles and projections.

Results

3D models and animations provide a dynamic visualization of the complex imaging procedure. All animations also provide a short description of each angulation, projection, and image, as well as other important notes related to clinical applications and scenarios. This allows students to learn the real-life scenarios and situations they might encounter in imaging patients in the hospital. This study could be extended for visualization in augmented reality (AR) where students can turn the 3D models around and manipulate the model in their own hands to perform the coronary angiography procedure.

Conclusion

3D models and animations in cardiac imaging education simplify abstract processes and enhance understanding, in line with the needs of the current generation and the fast-paced Industrial Revolution 4.0 (IR 4.0).
