Ultrasonography

4.5K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

    Purpose of the Study:

    • To investigate the combination of coded excitation and single-bit data capture for improving ultrasonic phased array imaging.
    • To assess the impact of this combined approach on image resolution, signal-to-noise ratio (SNR), and hardware requirements.

    Main Methods:

    • Utilized coded excitation pulses and single-bit data capture in an ultrasonic phased array system.
    • Employed pulse compression to recover image resolution from low-resolution data.
    • Performed phase coherence imaging (PCI) and total focusing method (TFM) on a carbon steel sample with tip diffraction.

    Main Results:

    • Achieved high SNR images comparable to conventional methods despite using single-bit data.
    • Demonstrated effective resolution recovery through coded excitation pulse compression.
