Introduction

MEDIVIS is an XR application in surgery. It creates the 3D models of the human body (organs) through Magnetic Resonance Imaging (MRI) scan, and then the 3D models can be used in AR as the environment. The application provides 3D realistic structure visualization for the human body through a VR environment, and the user can zoom the visualization (model).

Attractive Reasons

MEDIVIS provides two primary services: an AR-based surgical support platform and a VR/AR-based health education platform. The application combines two stages (training and working) with the same interface, which smooths the transaction for people from a student to become a surgeon. The teaching and reality tools intergrade together is a highlight which attracts me.

Another advantage of the application is that it offers medical students without qualifications to get real surgy experience. Every surgeon has the first time conducting the surgy for a realistic patient, but using the AR/VR platform beforehand can reduce the nervous or unskilled situations that may happen in real surgy. This improvement would increase the success rate for the surgy overall, which saves more lives.

Engaging Reasons

Compared to other XR applications, the highlights of MEDIVIS listed below make it stand out:

1. The application enables more medical students to have realistic chances to practice. By contrast, the number of medical students is more than the traditional practice materials they can conduct training.
2. Compared to the monitor screen or textbook, which only provides a 2D view, the application provides a 3D visualization of the human body (organs), which makes students benefit from the AR visualization as the real world is in 3D. Students obtain more intuitive interaction without relying on their imagination.
3. The application only needs a single glass to implement the provided features. The original devices used to support surgery, teaching, and training are sets of multiple large items. The application achieves better performance overall and is more convenient to use.

Highlights Features

Two main features are well done:

1. Reusable is a critical feature provided by the application. In the healthcare industry, every case is unique, and one limitation for practitioners is the experiences (illness cases) cannot be saved for further review in a traditional way. The AR application makes the model once and can keep it in the database to share for future reference.
2. Sharing the same view/opinion synchronously with other students makes abstract concepts in medical subjects easier to understand. With the 3D environment, students can get a deeper understanding of concepts, and communicating with others leads the learning experience to a new level. For example, the application could make students stand in the blood vessel to investigate around and look at the same parts together to discuss.

Improvable Features and the Way to Implement

1. Delay for realistic surgy may cause serious consequences. The devices for supporting surgery are connected wirelessly. The delay for using a cable is an order of magnitude reduction. The cable connection can make the platform more stable as well. Using high-band cables to connect devices when doing a realistic surgery instead of a wireless connection is necessary to improve delay and provide a more stable application.
2. Real-time scan modeling provides no pain discovery for patients would be a further improvement. This feature can benefit right before the realistic surgery to provide surgeon feedback for the patient and evaluate the risk of conducting the surgery, which reduces the danger of surgery. At the same time, creating a customized profile for patients is a benefit for further decision-making. The real-time investment needs more computing power and an efficient algorithm. Adding high-performance computing units and implementing a customized algorithm for this device would be the next step to improve the application.

Conclusion

In healthcare, the XR application brings a more intuitive way to better help both patients and doctors through its 3D visual interaction. It realizes the 3D existence in the real world, which greatly makes up for the lack of information caused by the lack of one dimension.
