Multiple input, multiple output communication systems and a method using multimode media are provided. An interior of the hermetic casing is kept at an intermediate pressure between a suction pressure and a discharge pressure. If the identifier has not been previously registered, the central server creates an association between the identifier and the wireless network, which is stored in a database maintained by the central server. Pixels of a two-dimensional sheared image having a plurality of lines of pixels are then determined from voxel values of the object volume data set identified by the shear mapping.
