Munich-based CAT PRODUCTION and CAT MEDIC recreate human anatomy in 3D—inviting VR users and consumers of other media to take a journey through their own bodies. Executive director Johannes Atze explains

VRWT: What is CAT PRODUCTION AND CAT MEDIC’s background and what do they do today?

Johannes Atze: CAT MEDIC is a brand for products of CAT PRODUCTION, an animation studio that has been in operation since 1993. In 2010, the studio began focusing on medicine and in that time we have developed detailed 3D representations of human anatomy. This was the starting point of our custom productions and for CAT MEDIC, which today develops an in-house app, an image library and an interactive animated anatomy chart.

VRWT: Where are your visualisation solutions gaining the most traction and why?

Johannes Atze: For the past three years, we have produced animations for interactive 360-degree journeys through the body. Most of our productions have been developed for the pharmaceutical industry and for a Bavarian ministry for public education purposes.

The public is very interested in how the body works, which has prompted healthcare companies, medical practices, clinics and government organisations to respond to their desire for this kind of content. Studies show that knowledge conveyed via VR has a greater impact than traditional media. And anyone who has ever experienced an interactive 360-degree journey through the body knows what I’m talking about.

VRWT: What are some of the things you’ve been able to achieve for your clients in the healthcare space?

Johannes Atze: For most of our new customers, this kind of production is a new experience for them. At first, they tend to be surprised at how manageable the costs are. Due to the sophistication of our modelling methods, the majority of budgets are spent on visualisation and animation. This means that our customers receive high-end productions for a fair price. Secondly, they can use the content for a whole range of media platforms.

VRWT: What do you have planned for this year?

Johannes Atze: We are taking part in two research projects. One is a VR surgery training system with realistic haptic feedback where surgeons practice milling of the acetabulum before inserting an artificial hip. This was completed successfully. In May, we will begin working on the replacement of the femoral part.

The second research project is under the leadership of the Munich School of Robotics and Machine Intelligence, a new institute of the Technical University of Munich. We are developing a digital twin of the shoulder, arm and hand for a complex VR system.

With our partners, we will continue to develop the VR journey into the body, which is accompanied by adapted programming of massage chairs. One task of the system will be to show patients what could happen if they do not change their lifestyles. With this system, they will learn what happens during a heart attack, a stroke and other lifestyle diseases.
