Abstract

In a method of identifying gaseous bubbles in a liquid, an ultrasound contrast agent is introduced into the liquid so as to form gaseous bubbles in the liquid. A first ultrasound pulse centered at a first frequency is directed onto the bubbles so as to cause the bubbles to undergo a first oscillating size change and produce a first oscillating echo signal corresponding thereto. The first oscillating echo signal produced by the bubbles is detected, and the bubbles are identified based upon the detected first echo signal.

Claim

What is claimed is: 1. A method of identifying gaseous bubbles in a liquid, comprising: a) introducing an ultrasound contrast agent into a liquid so as to form gaseous bubbles in said liquid; b) directing a first ultrasound pulse centered at a first frequency onto said bubbles so as to cause said bubbles to undergo a first oscillating size change and produce a first oscillating echo signal corresponding to the first oscillating size change of the bubbles; c) detecting the first oscillating echo signal produced by said bubbles; d) identifying said bubbles based upon the detected first echo signal; e) directing a second ultrasound pulse centered at a second frequency different from said first frequency onto said bubbles, so as to cause said bubbles to undergo a second oscillating size change and produce a second oscillating echo signal corresponding to the second oscillating size change of the bubbles; f) detecting the second oscillating echo signal produced by said bubbles; and g) further identifying said bubbles based upon the detected second echo signal. 2. The composition of claim 1, wherein said steps further include the step of comparing the first echo signal with a first reference echo signal indicative of said bubbles, so as to identify said bubbles. 3. The composition of claim 1 wherein said first frequency is about a resonant frequency of said bubbles. 4.

Abstract

A visceral barrier has a barrier element that is changeable between an opened and a closed configuration. The barrier element may be positioned while in the opened configuration to temporarily reposition the viscera within the body cavity. A method of repositioning the viscera in a body cavity of a patient during a surgical procedure includes providing a visceral barrier, introducing the visceral barrier into the body cavity when the barrier element is in the closed configuration, opening the barrier element to the opened configuration, and positioning the barrier element within the body cavity to reposition the viscera and provide a space for performing a surgical procedure.

Abstract

Transmit based axial whitening is provided. Ultrasonic waveforms to be transmitted are designed to provide for wideband imaging characteristics prior to detection. Rather than transmitting a waveform having a spectral magnitude as white or flat as possible, waveforms with adjusted spectral content, such as spectrally bi-modal waveforms are generated in order to compensate for subsequent effects. Prior to detection, a more wideband or whiter signal response is provided in response to the transmitted waveform. Any of various alterations of the transmit waveform, such as asymmetric, spectrally bi-modal or other characteristics in anticipation of a system transfer function or physical phenomena through which the signal passes electronically or acoustically to result in a wideband or white spectral magnitude and generally linear spectral phase is used. The transmit waveform is altered to improve the imaging characteristics of the downstream processing.

Abstract

A cooling device for an electric or electronic apparatus includes an inhaling member formed to draw in air and then discharge the air heated by heat generated from a component of the electric or electronic apparatus, an exhausting member communicating with the inhaling member and formed to receive the heated air discharged from the inhaling member, a fan provided adjacent to the exhausting member to forcibly draw in the air from the exhausting member, and a heat exchanger absorbing the heat from the air discharged from the fan and discharging the heat through a body casing of the electric or electronic apparatus. The cooling device for the electric or electronic apparatus has a high cooling efficiency, reduces noise, and prevents an inflow of dust.
