Abstract:

Featured are devices for compression of target tissue while magnetic resonance imaging the target tissue and methods and systems related thereto. The method includes disposing target tissue between the fixed surface and the moveable member of a compression device and compressing the target tissue between the fixed surface and the moveable member. The method also includes acquiring one or more, more specifically a plurality, of sequences of image data of the compressed target tissue using an MRI imaging technique (MRI). In particular embodiments, the MRI technique is a SENC MRI technique, where tissue encoding is done prior to compressing the tissue and acquiring includes adding a gradient moment in the slice-selection direction to cause demodulation with a specific frequency. In further embodiments, the sequences of image data are acquired one of during successive periodic compressions of the tissue or successive periodic relaxation of the tissues.

Appl. No.:

14/000003

Inventors:

Michael A. Jacobs - Sparks MD, US

Assignee:

THE JOHNS HOPKINS UNIVERSITY - Baltimore MD

International Classification:

G06T 3/40

US Classification:

382131, 382296

Abstract:

Featured are methods and systems for reslicing-based nonrigid registration of multiparametric and modality images or objects. In such registration methods, global motion is modeled by multiple affine transforms (rigid), while local motion and slices matching is estimated using non-uniform radial reslicing of RTV to search for best match between reference volume slices and resampled target volume (RTV), orthogonally re-sliced to higher spatial resolution compared to the spatial resolution of the reference volume. The reference and target volumes can be in any plane and the method presented in this invention transfers them to target plane which can be any of axial, coronal, or sagittal and there is no need for the original and target scanning planes to be the same.

International Classification:

G06T 11/00

US Classification:

382132

Abstract:

Featured are methods and systems to multiparametric non-linear dimension reduction (NLDR) methods for segmentation and classification of radiological images. Such methods for segmentation and classification of radiological images, includes pre-processing of acquired image data; and reconstructing the acquired image data using a non-linear dimension reduction technique so as to yield an embedded image representing all of the acquired, where the acquired image data comprises a plurality of different sets of image data of the same region of interest. Such NLDR methods and systems are particularly suitable for the ability to combine multiple input images into a single unit for increased specificity of diagnosis.

International Classification:

H04L 29/06

US Classification:

370328

Abstract:

A system and method are provided for converting radio communication signals between a Digital Fixed Station Interface (DFSI) Internet Protocol (IP) APCO P25 standard communications format and binary serial data protocol standard communications. Received serial binary data may be evaluated, separated into control information and data payloads, and converted to DFSI IP standard data. Incoming and outgoing data communications are processed by implementing decisions about how to handle the information contained in, or to be contained in, the incoming and outgoing data communications based upon the substance, or overarching format, of the data contained in individual data packets, or serial bit streams. In embodiments, decisions and determinations regarding the information include determining that the information is damaged or corrupted and therefore not available to be converted. The data may be discarded based on such a determination.

Abstract:

The ability to identify anomalous behavior in video recordings is important for security and public safety. Current identification techniques, however, suffer from a number of limitations. The present invention describes a novel identification technique that permits unsupervised, automatic identification of moving objects and anomaly detection in real-time recordings (MovA). The present invention specifically utilizes a novel real-time manifold learning system (RML), which generates a semantic crowd behavior descriptor that the inventors call a Trackogram. The Trackogram can be used to identify anomalous crowd behavior collected from video recordings in a real-time manner. MovA can be used to detect anomaly in standard video datasets. Importantly, MovA is also able to identify anomalies in night-vision stereo sequences. Ultimately, MovA could be incorporated into a number of existing products, including video monitoring cameras or night-vision goggles.

Abstract:

Systems and methods are disclosed to intelligently employ antenna resources in a manner that may reduce interference between communications signals even in instances where multiple separate frequency band communications need to be supported in a vehicle of limited size. A manifold antenna system is proposed that provides a scheme and a physical construct whereby multiple individual radio receiver/transmitter units may share a limited number of transmitting and receiving antennas. The disclosed manifold antenna system is particularly adaptable to aircraft, spacecraft, vessel or vehicle applications where there is limited room for mounting a number of individual antennas as may be needed to support each radio receiver/transmitter unit in an effort to minimize an amount of interference as is conventionally caused by having transmitting antennas located in too close a proximity to receiving antennas.
