This means that we can visualize the morphology of the otolith and otolith organs in the bony labyrinth under normal conditions and their morphological changes under unstable woozy. This imaging technique allows us to simultaneously visualize in the 3D bony labyrinth of the inner ear and the tissue consisting of calcium carbonate (CaCO 3) within it. When combined with the volume rendering algorithms 6, 7, these algorithms will create a new algorithm for reconstructing the in vivo otolith and the otolith organs. We propose the new technique based upon the multi-resolution neighborhood matching technique but the powerful method is effective at synthesizing a wide range of textures. Because texture synthesis is an important technology for graphics and animation and fits for imaging these thin anatomical structures 5. A texture synthesis algorithm is useful for reconstructing the otolith and the otolith organs. The solution to these problems is to establish the in vivo imaging computer technique for thin otolithic membranes from their imaging data set.

If we can know in vivo conditions of the otolith and the otolith organs, we can reveal several unknown functions and metabolisms. Little is known about in vivo morphological conditions and their metabolisms, so our knowledge of them is still unclear. Therefore, it can be imagined that these otolith organs may be inconstant morphological shapes in the in vivo inner ear. The utricular signals affect eye movements, and the saccular signals usually go to muscles to maintain our posture 1, 2, 3, 4. The otolith organs as the saccular and utricular maculae detect linear accelerations and decelerations. The semicircular canal systems identify the circulation movement. The sensory organ of the vestibular systems consists of the saccular macula, the utricular macula, and three cristae of the superior, lateral, and posterior semicircular canals. The vestibular end-organs play in motion, equilibrium, and spatial recognition. Keeping a balance is maintained by the brain’s output from a complex set of sensorimotor control systems inputs, which are visual, muscles, joints, and the vestibular end-organs. Movements and balance are controlled by sensorimotor systems as sensory peripheral organs such as vision, tactile, and the vestibular end-organs. This imaging technique will contribute to our understanding of pathology and calcium metabolism in the in vivo vestibulum. These created 3D microanatomical images can allow detailed observations of changes in physiological and biological information. The saccule, utricle, and endolymphatic sac were not constantly shaped according to their conditions. In benign paroxysmal positional vertigo (BPPV), the otolith increased in the utricular macula but did not change much in the saccular macula. In Meniere’s disease (MD), the saccular macula was larger and the utricular macula was smaller. Both shapes and volumes were not always constant depending on time.

The changes in the amount of CaCO 3 in the maculae and the endolymphatic sac showed various morphologies, reflecting the balance status of each subject. The saccular macula was almost bud-shaped. The utricular macula was elongated pea-shaped. The otolith and otolith organs images were reconstructed from a texture synthesis algorithm under the skull volume rendering algorithm using a cutting-plane method. We will create the technique for 3D microanatomical images of them, and investigate the in vivo internal state and metabolisms. Although the otolith and otolith organs correlate with vertigo and instability, there is no method to investigate them without harmful procedures.
