Doppler Effect - II01:05

Doppler Effect - II

4.2K
The Doppler effect has several practical, real-world applications. For instance, meteorologists use Doppler radars to interpret weather events based on the Doppler effect. Typically, a transmitter emits radio waves at a specific frequency toward the sky from a weather station. The radio waves bounce off the clouds and precipitation and travel back to the weather station. The radio frequency of the waves reflected back to the station appears to decrease if the clouds or precipitation are moving...

Doppler Effect - I

5.6K
The Doppler effect and Doppler shift were named after the Austrian physicist and mathematician Christian Johann Doppler in 1842, who conducted experiments with both moving sources and moving observers. Consider an observer standing on a street corner, observing an ambulance with a siren sound passing by at a constant speed. The observer experiences two characteristic changes in the sound of the siren. Initially, the sound increases in loudness as the ambulance approaches and decreases in...

Assessing Blood pressure using a doppler ultrasound

2.1K
To obtain accurate blood pressure measurements in clinical settings, especially when traditional methods are insufficient, healthcare professionals utilize the Doppler ultrasound technique. This method uses high-frequency sound waves to detect blood flow within the arteries, which is crucial for patients with conditions that complicate circulatory system assessment.

Equipments Used To Measure Blood Pressure

Direct Method
This invasive approach involves cannulating a peripheral artery. During each cardiac contraction, pressure generates mechanical motion within the catheter, transmitted through rigid, fluid-filled tubing to a transducer. This transducer converts mechanical motion into electrical signals displayed as waveforms on a monitor. An automatic flushing system prevents blood backflow. Due to the potential risk of unexpected arterial blood loss, this method is primarily used in intensive...

    Area of Science:

    • Biomedical Engineering
    • Acoustic Imaging
    • Ultrasound Therapeutics

    Background:

    • Therapeutic ultrasound with microbubbles requires precise control of microbubble activity and location.
    • Passive acoustic mapping (PAM) can locate microbubble activity but struggles with rapid microbubble movement.

    Purpose of the Study:

    • To develop and validate a technique for imaging microbubble movement by estimating their velocities within the ultrasound focal volume.
    • To assess the feasibility of Doppler PAM for real-time monitoring of microbubble dynamics in therapeutic ultrasound.

    Main Methods:

    • Microbubbles in a tissue-mimicking material were sonicated with focused ultrasound.
    • Acoustic emissions were captured, and PAM with robust Capon beamforming localized sources.
    • Spectral analysis of time traces and Doppler shifts were used to construct microbubble velocity maps.

    Main Results:

    • Microbubbles exhibited velocities around 1 m/s, primarily moving away from the transducer due to acoustic radiation forces.
    • Both away and toward motion were detected, influenced by acoustic forces and ultrasound-induced fluid motion.
    • High-speed optical imaging validated the Doppler PAM-derived microbubble velocities.

    Conclusions:

    • Doppler PAM provides a passive method for estimating microbubble motion during therapeutic ultrasound.
    • This technique has potential applications in targeted drug delivery, sonoporation, and sonothrombolysis.
