3D X-ray CT is widely used in medical, non-destructive testing, and security fields to visualize internal structures of objects. However, CT data are stored as volumetric voxel data, whereas humans primarily perceive three-dimensional structures from two-dimensional visual information using binocular disparity.
In this study, we propose a mixed reality (MR) visualization method that integrates a haptic device, enabling users to not only observe but also “touch” internal structures derived from X-ray CT data. The developed system consists of a PC, a spatial display, and a haptic device, allowing users to perceive reaction forces and resistance when interacting with virtual structures.
By combining visual and haptic feedback, the proposed method enhances intuitive understanding of boundaries, thickness, and spatial relationships of internal structures, particularly in cases involving overlapping components or limited visibility.
