HIGH PULSE REPETITION FREQUENCY FOR DETECTION OF TISSUE MECHANICAL PROPERTY WITH ULTRASOUNDDetection of tissue response is provided with a high pulse repetition frequency. A sequence of separable signals is transmitted in one event. For example, pulses at different frequencies are transmitted as separate...
We report that (1) calcium signaling increases with the application of ultrasound; (2) the neuronal response rate to ultrasound is dependent on pulse repetition frequency (PRF); and (3) ultrasound can reversibly alter the inhibitory effects of tetrodotoxin (TTX) in pharmacological studies. This ...
Automatic adjustment of velocity scale and pulse repetition frequency for doppler ultrasound spectrogramsAutomatic adjustment of velocity scale and pulse repetition frequency for doppler ultrasound spectrogramsAn ultrasound transmitter generates ultrasound signals at an adjustable pulse repetition rate. A Doppler ...
Microbubble cavitation can be controlled by tuning ultrasound parameters (e.g., pressure amplitude, frequency, pulse repetition frequency, burst length). Low acoustic pressures induce stable cavitation (alternation of expansion and shrinkage of microbubbles) near the vessel wall that can result in tight...
The samples are end-ground to improve the ultrasonic coupling between the transducer holders and the samples before ultrasound couplant is coated on to the faces of the ultrasonic loading platens. Ultrasonic coupling is further enhanced by use of thin lead foil between the samples and the loading...
Time domain formulation of pulse-Doppler ultrasound and blood velocity estimation by cross correlation The Doppler effect is usually described as a frequency shift of the backscattered signals from moving targets with respect to the frequency transmitted. Re... O Bonnefous,P Pesqué - 《Ultrason ...
The objective of this study was to further assess the role of inertial cavitation in ultrasound-induced lung hemorrhage by examining the effect of pulse polarity at a common in situ (at the lung surface) peak rarefactional pressure [pr(in situ)] and at a common in situ pulse intensity integ...
Define Pulse Technology. Pulse Technology synonyms, Pulse Technology pronunciation, Pulse Technology translation, English dictionary definition of Pulse Technology. Noun 1. battery charger - a device for charging or recharging batteries charger device -
the use of various physical agents (for example, electric current, ultrahigh-and superhigh-frequency electromagnetic-field oscillations, ultrasound, mechanical pressure, and light) for therapeutic purposes. In pulse therapy the energy of the agent is applied to the body in the form of separate ...
Superthreshold Behavior of Ultrasound-Induced Lung Hemorrhage in Adult Rats Role of Pulse Repetition Frequency and Pulse Duration The purpose of this study was to enhance the findings of an earlier ultrasound-induced lung hemorrhage study (Ultrasound Med Biol 2003; 29:1625-1634) that estimated pressu...
