# 3D Visualization in Digital Medicine Using XR Technology
## 4 Discussion  
The basic idea of our research was to design a solution that would provide doctors and researchers with the opportunity to evaluate digitized pathology serial sections in a comfortable and customizable 3D environment. In order to make this evaluation as immersive as possible, we used virtual reality technology. Using VR technology, we were able to create a 3D environment that the doctor can share with colleagues to jointly evaluate the medical data displayed. Our research had two goals. First, we have established equations that can be universally used for 3D visualization not only of digitized medical tissue samples used in pathology, but also of any digitized medical image data based on the DICOM standard. Based on Section 3.3, it can be said that the star based solution gave the best results regarding the parameters that directly affect the user experience (loading time, frame rate), but it should be mentioned that voxel-based solutions also have their own advantages. The second aim of our research was to use the visualization possibilities offered by VR technology. In the Section 3.4 we have described the different zoom functions we have developed. This feature is also found in 2D visualization software used today, but in our case it has been implemented in 3D, virtual reality. Based on the test results obtained during our research, further optimization solutions can be implemented in order to achieve even better results in the field of 3D visualization of digitized medical samples. The resolution of serial sections displayed in virtual reality must be further increased in the future in order to make the displayed 3D model and certain parts of the model suitable for making diagnostic decisions. Increasing the displayed resolution can be achieved by using technologies such as GPU programming. Basically, with our research, we wanted to create a work environment that is comfortable for the pathologist, customizable, and has the most basic functionalities that the pathologist may need when evaluating a 3D serial section. The basic premise of our research is that in the future the pathologist will be able to evaluate tissue samples with the help of XR technologies more easily, faster and more precisely. In addition to the development results of our research, we also wanted to show with our paper that the technology is already there today, that image data generated in medicine can be displayed even in virtual reality. With our research we also wanted to show that virtual reality can provide an interdisciplinary environment that has no spatial limitations. With our solution, it will be possible for doctors and researchers to share their medical data with each other in the 3D space provided by virtual reality. In the future, it will be possible for doctors from different fields of medicine to create a diagnosis together in a common virtual 3D environment by examining the same 3D sample. With this solution, the time needed to establish a diagnosis can be shortened, as physical barriers between doctors working on the same case can be eliminated. Of course, setting up a common virtual 3D lab environment has many requirements. Such requirements include secure data management between users, authentication, and low-latency data transmission. In the course of our research, we have successfully developed a solution that can visualize medical samples stored in DICOM format in 3D and zoom in on either the displayed 3D model or on an element of the model. During our research, we have created a solution within the developed software that allows the user to perform volume measurements on a specific region of the displayed 3D model in a VR environment. In the future, we would like to further develop the display solutions to be able to visualize different metadata for the samples together with the 3D serial section. According to our plans, in the next period, we will realize that our software can be used by several pathologists at the same time, thereby creating an opportunity to establish a common diagnosis.
