Reconstruction of Signal using Interpolation

920
Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

Ultrasonography

6.5K
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...

    Area of Science:

    • Medical Imaging
    • Ultrasound Technology
    • Signal Processing

    Background:

    • Traditional delay-and-sum (DAS) beamforming for ultrasound image reconstruction is primarily one-dimensional.
    • This limits the contribution of individual receiving elements and time points to pixel generation.

    Purpose of the Study:

    • To introduce a new two-dimensional (2D) algorithm for reconstructing ultrasound images from raw radiofrequency (RF) data.
    • To enhance image quality, spatial resolution, and contrast compared to existing methods.

    Main Methods:

    • Developed a 2D reconstruction algorithm utilizing matrix inversions to create a reusable reconstruction matrix.
    • Image generation involves a single matrix multiplication with raw RF data, bypassing envelope detection and gridding.
    • Acquired RF data using a digital ultrasound engine for various probe configurations and field-of-view (FOV) types.

    Main Results:

    • The proposed 2D method demonstrated a 20-38% reduction in point spread function (PSF) size and spatial integral compared to DAS.
    • Ultrasound images reconstructed with the new algorithm exhibited superior spatial resolution and contrast on a quality-assurance phantom.

    Conclusions:

    • The proposed 2D reconstruction algorithm offers significant improvements in ultrasound image quality.
    • This method provides a more effective approach to reconstructing ultrasound images from raw RF data.
