Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been developed.
Ultrasonography01:17

Ultrasonography

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 a...

    Summary

    A novel super-resolution ultrasonic imaging technique enhances resolution by adaptively focusing on desired points and suppressing other signals. This method achieves superior performance compared to existing techniques for localized objects.

    Area of Science:

    • Acoustics
    • Medical Imaging
    • Signal Processing

    Background:

    • Conventional ultrasonic imaging methods face limitations in achieving high resolution, particularly for complex or localized structures.
    • Existing super-resolution techniques may not optimally address signal suppression in specific regions, impacting image clarity.

    Purpose of the Study:

    • To introduce a new super-resolution ultrasonic imaging method utilizing adaptive focusing.
    • To enhance image resolution and signal-to-noise ratio by intelligently illuminating target areas and suppressing unwanted signals.

    Main Methods:

    • Acquisition of reflected wave field data using all transducer pairs.
    • Object-dependent adaptive focusing to illuminate desired points and create signal nulls in other regions.
    • Numerical image reconstruction via wave field data matrix manipulation, eliminating the need for physical beam scanning.
