Abstract: When an amount of visceral fat is measured using ultrasonic waves during medical examination of metabolic syndrome, three contact positions are defined on the surface of the abdominal region, and three distances inside the living body are measured by bringing a probe into contact with the surface of the abdominal region at the contact positions. Specifically, three measurement paths having a starting point at the center of the descending aorta are set, and the distances from the center to a surface of the fat layer adjacent to the surface of the body (inner surface of the subcutaneous layer) in the measurement paths are observed. An approximate area of a visceral fat region can be determined from the three distances and two angles defined by the three measurement paths, and an index value is calculated on the basis of the area. A probe holder having three holding portions is desirably used.

Abstract: The present invention provides a method for displaying a three-dimensional image without using a lens array with aberration and a highly defined flat display. The method comprises steps of arranging a plurality of basic units 8a, 8b, 8c . . . two-dimensionally; inputting image signals to the respective basic units 8a, 8b, 8c . . . ; and projecting light beams emitted from light sources 9a, 9b, 9c . . . two-dimensionally in space by driving the respective basic units in accordance with the inputted image signals. Light beams before emitting from the light sources are respectively modulated in their luminance in accordance with movements of the two-dimensionally projected light beams.

Abstract: The present invention provides a method of manufacturing a lens array for recording or reproducing three-dimensional images with enhanced precision comprising uniform convex lenses of excellent optical properties without difficulties. A plurality of circular plateaus 3m having uniform diameter and shape are formed two-dimensionally arranged with high precision on a transparent substrate 3 by utilizing a laser plotter or an electron beam exposure system. A predetermined amount of transparent liquid resin 5 is dropped onto the respective circular plateaus one after another. The transparent liquid resin is left as it is until it forms dome shapes on the respective plateaus due to its surface tension. The dome shaped transparent liquid resin 5? is hardened, so that the lens array having excellent and uniform optical properties two-dimensionally regularly arranged is obtained.

Abstract: The present invention provides a three-dimensional image display device capable of reproducing clear, deviation-free and distortion-free three-dimensional images generated by a three-dimensional generating method. The three-dimensional image display device 4 comprises a lens array 1 having the predetermined number of convex lenses arranged in a matrix; and image display means for displaying a plurality of two-dimensional images 3 corresponding to the respective convex lenses. The same lens array 1 is employed in the three-dimensional display device as the lens array employed for generating the two-dimensional images.
