Ultrasonography

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...

Imaging Studies II: Ultrasonography

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Curvilinear Motion: Rectangular Components

Curvilinear Motion: Rectangular Components

Curvilinear motion characterizes the movement of a particle or object along a curved path, notably evident when envisioning a car navigating a winding road. If the car starts at point A, its position vector is established within a fixed frame of reference, where the ratio of the position vector to its magnitude signifies the unit vector pointing in the position vector's direction.
As the car advances, its position evolves over time. Quantifying the car's velocity involves computing the time...

Relative Motion Analysis using Rotating Axes

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it instrumental in...

Medical Imaging
Ultrasound Technology
Signal Processing

Background:

Complementary coded pulses in ultrasound enhance SNR but can suffer from side-lobes due to tissue motion.
Tissue motion causes misalignment in complementary filter outputs, leading to artifacts and reduced image quality.

Purpose of the Study:

To develop and validate a robust method for filtering and motion compensation of complementary coded ultrasound signals.
To mitigate side-lobe artifacts caused by tissue motion in ultrasonic imaging.
To improve image quality and maintain frame rates in complementary coded ultrasound systems.

Main Methods:

A novel filtering and motion compensation technique for complementary coded signals was developed.
The method incorporates mirrored compensation stages to minimize motion estimation error impact.
Robustness to non-ideal transducer effects was integrated into the signal processing chain.

Main Results:

The proposed method significantly reduces side-lobes, achieving levels comparable to FM-coded signals.
It offers improved coding gain and range resolution compared to existing methods.
Motion compensation enabled data utilization without the typical frame-rate penalty associated with complementary coding.

Conclusions:

The developed filtering and motion compensation method effectively addresses side-lobe artifacts in complementary coded ultrasound.
This technique enhances image quality and maintains high frame rates, making it suitable for medical imaging applications.
The method's robustness and performance were validated through simulations and experimental verification.
