Abstract: Techniques and systems are disclosed for performing mechanical ablation of blood clots using low-intensity ultrasound. A system includes a computed tomography (CT) scanner to acquire axial scans of a target subject containing at least one intravascular blood clot, and generate volumetric CT data of the target subject based on the acquired axial scans. A data processing device is in communication with the CT scanner to process the generated volumetric CT data, and identify at least one parameter of an ultrasound beam to ablate the at least one intravascular blood clot based on the processed volumetric CT data. Also, an ultrasound ablation device is in communication with the data processing device to generate the ultrasound beam based on the identified at least one parameter, and apply the generated ultrasound beam with the identified at least one parameter to ablate the at least one intravascular blood clot.

Abstract: A method of improving the electromagnetic (EM) shielding performance of a mposite material is provided. The composite material has conductive and semi-conductive filler particles suspended in a non-conductive resin. The filler particles can be up to 40 weight percent of the composite material. The composite material is electroplated with a conductive material onto a portion of its surface to improve the electrical connection between the conductive material and a portion of the filler particles. EM shielding performance can be further enhanced by injecting an exponentially decaying electromagnetic pulse through the composite material that has been electroplated.

Abstract: A magnetic resonance (MR) imaging system includes a magnet for producing a magnetic field to which a patient is subjected, a radio frequency (RF) transmitter coupled to a body coil within the magnet, an RF receiver coupled to a surface coil within the magnet and placed as close as possible to tissue being analyzed by the MR imaging system, and a computer controlled system for generating RF signals sent from the transmitter and detected by the receiver for use in producing nuclear excitation and corresponding detected induced currents in the surface coil sent to an analog-to-digital converter and then to the computer for processing into an image display of the tissue under analysis.
