Preferred embodiments of the present invention provide a system and method for the management of virtual storage. Magnetic field gradients are applied to the sample to select for acquisition components of each MR echo signal. The invention includes expandable implantable conduits and expandable bioprosthetic stented valves. Measured parameters associated with the measured conductivity topology and derived from the acoustic data can be used to generate a time-reversed mirror acoustic treatment signal that can be used to apply a therapeutic treatment to a target tissue within the region of interest. Circuit devices can be mounted to the surface of the deposited interconnect layer at locations that minimize, or substantially minimize, the interconnect length between the chip device and the decoupling capacitors for that circuit device. The optical fiber includes at least one kind of metallic nanostructure that is capable of generating surface plasmon resonance in the optical fiber.
