Abstract: A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.

Abstract: An imaging system, which improves the optical revolution and reduces optical alias of a solid state imager comprises a lens and a modulating element, which alters incident radiation in such a manner as to displace the image by fractions of a pixel between adjacent fields by either mechanically shifting the elements or by electro-optic variations of refractive index. A processing system is also provided, in which alternate fields are interlaced and output to a monitor. The modulator is arranged in a demountable manner, so that it can be "bolted on" as an additional attachment to a standard camera. The processing system is attached via the original CCD output terminal.
