ABSTRACT
This chapter discusses the three-dimensional representation of complete voxel data including internal structures obtained from invisible information, X-ray computed tomography (CT). Since humans are always aware of three dimensions but use surface information of objects, three dimensions including internal structures such as X-ray CT are difficult to understand. In this chapter, we introduce the use of extended reality (XR) to achieve a representation that is easy for humans to understand, as well as a method to facilitate pointing of the desired location of 3D information. In addition, examples of these applications in the medical field are presented, showing that xR can be used not only for X-ray CT but also for magnetic resonance imaging (MRI) and other types of information that can provide 3D information including internal structures.
