Development of Augmented Reality Body-Mark System to Support Echography

We propose visualization system of 3D shape of internal organs using Augmented Reality and Virtual Reality technology. Echography has been used in every field of medical diagnosis because of its safety and cost-effectiveness. Therefore, portable echography device so called "Ubiquitous Echo" was released by many manufacturers. However, the skill to recognize relationship between ultrasound probe and internal organ is required to acquire echogram. Therefore we have developed tracking system of probe orientation to transfer 2D position of echogram into 3D space. Then we have applied Radial Basis Function Interpolation to reconstruct the shape of internal organs. Furthermore, GUI interface to visualize the internal organ was developed by OpenGL. As a result of evaluation experiments, visualization of internal organ was satisfied to show the echogram for diagnosis.
