Sub-Nanowatt Ultrasonic Bio-Telemetry Using B-Scan Imaging

Ultrasonic elastography using sector scan imaging and a radial compression.

Elastography is an imaging technique based on strain estimation in soft tissues under quasi-static compression. The stress is usually created by a compression plate, and the target is imaged by an ultrasonic linear array. This configuration is used for breast elastography, and has been investigated both theoretically and experimentally. Phenomena such as strain decay with tissue depth and strai...

On Modeling the Tissue Response From Ultrasonic B-Scan Images - Medical Imaging, IEEE Transactions on

AbstructWe model tissue as a collection of point scatterers embedded in a uniform media, and show that the higher-order statistics (HOS) of the scatterer spacing distribution can be estimated from digitized radio frequency (RF) scan line segments and be used in obtaining tissue signatures. We assume that RF echoes are non-Gaussian, on the grounds of empiricaVtheoretical justifications presented...

Development of Wireless Bio-telemetry System Using Fm Stereo Method

Development of telemetry system is used for Transmission and detection of vital body signals. The transmitting unit detects and sends two kinds of patient’s vital signals. The stationary receiving unit receives and analyzes the signals and alerts a nurse to the dangers of the patient if necessary. The system could be simplified and minimized in size by using commercialized electronic components...

On modeling the tissue response from ultrasonic B-scan images

The authors model tissue as a collection of point scatterers embedded in a uniform media, and show that the higher-order statistics (HOS) of the scatterer spacing distribution can be estimated from digitized radio frequency (RF) scan line segments and be used in obtaining tissue signatures. The authors assume that RF echoes are non-Gaussian, on the grounds of empirical/theoretical justification...
