OBJECTIVES The aim of this study is to investigate the correlation between 2-dimensional (2D) cephalometric measurement and 3-dimensional (3D) cone beam computed tomography (CBCT) measurement, and to evaluate the availability of 3D analysis for asymmetry patients. MATERIALS AND METHODS A total of Twenty-seven patients were evaluated for facial asymmetry by photograph and cephalometric radiogr...

Two pilot studies investigated potential sources of error in static human body surface measurement for conventional anthropometry methods and three-dimensional electromechanical methods under different experimental conditions. In the first pilot study, two anthropometrists measured Humeral breadth, Radiale-Stylion length and Wrist breadth of a cadaveric arm repeatedly in nearly nude and lightly...

In this study, to measure the human finger’s tactile sensation capability of recognizing a fine surface texture using psychophysical experiments, a computer-controlled measurement system that presents fine step-heights of 0 to 1000 μm to human subjects’ fingers at various presentation angles were developed. The measurement system can control four parameters of fine step presentation, i.e., the ...

Vertical resolution is the most widely quoted and most frequently misunderstood performance specification for equipment that measures surface topography. Here I propose to use internationally standardized terms and definitions for measurement noise and surface topography repeatability as more meaningful quantifiers for measurement performance. A specific example is an interference microscope op...
