We report an integrated ultrasound (US) and optical coherence tomography (OCT) probe and system for intravascular imaging. The dual-function probe is based on a 50 MHz focused ring US transducer, with a centric hole for mounting OCT probe. The coaxial US and light beams are steered by a 45° mirror to enable coregistered US∕OCT imaging simultaneously. Lateral resolution of US is improved due to focused ultrasonic beam. Mirror effects on US were investigated and invitro imaging of a rabbit aorta has been carried out. The combined US-OCT system demonstrated high resolution in visualizing superficial arterial structures while retaining deep penetration of ultrasonic imaging.

    We show how in ultracold Fermi gases the difference between the finite temperature T structure factors, called S-(ω,q), associated with spin and density, reflects coherent order at all ω, q, k_{F}a, and T. This observation can be exploited in two photon Bragg scattering experiments on gases which...

    The piezoelectric response of [001] poled domain engineered (1-x)Pb(Mg(13)Nb(23))O(3)-xPbTiO(3) (PMN-PT) crystals was investigated as a function of composition and phase using Rayleigh analysis. The results revealed that the intrinsic (reversible) contribution plays a dominant role i...
