The MEMS (Micro-Electro-Mechanical-Systems) technology is quickly evolving as a viable means to combine micro-mechanical and micro-optical elements on the same chip. The methods for MEMS fabrication are based on those already used in the well established semiconductor industry. Dry and wet etching of deposited, grown, or bulk layers is used to form movable(More)
PURPOSE The influence of angular deformity of the scaphoid on wrist function and arthrosis is debated and the reliability of the described quantitative measurements of deformity has been questioned. We hypothesized that the inherent imprecision with which computed tomography scanning planes are selected introduces another source of variability in(More)
