Therapeutic ultrasound (US) can be noninvasively focused to activate drugs, ablate tumors and deliver drugs beyond the blood brain barrier. However, well-controlled guidance of US therapy requires fusion with a navigational modality, such as magnetic resonance imaging (MRI) or X-ray computed tomography (CT). Here, we developed and validated tissue characterization using a fusion between US and ...

This study attempts to compare the signal-to-noise ratio (SNR) of the 40 mm High-Temperature Superconducting (HTS) surface resonator at 77 K and the 35 mm commercial quadrature (QD) surface resonator at 300 K in a 3 Tesla (T) MRI imager. To aquire images for the comparison, we implemented a phantom experiment using the 40 mm diameter Bi2Sr2Ca2Cu3Ox (Bi-2223) HTS surface resonator, the 35 mm com...

This article presents an innovative architecture for the implementation of electrostatic discharge (ESD) protection millimeter-wave (mm-wave) devices. The proposed is based on use 3-dB couplers, whose coupled outputs have been shorted to ground node. In order reduce physical dimensions coupler and reach high coupling required this application, Coupled Slow wave CoPlanar Waveguides (CS-CPWs) was...
