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...

Physical Assessment of the Respiratory Tract III: Percussion

Physical Assessment of the Respiratory Tract III: Percussion

The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.

Summary

High intensity focused ultrasound (HIFU) can treat liver tumors but risks skin burns from rib absorption. This study introduces a DORT method to focus ultrasound on targets while sparing ribs, significantly reducing energy absorption by up to 100-fold.

Background:

High intensity focused ultrasound (HIFU) shows promise for treating liver tumors like hepatocarcinoma.
A significant clinical challenge is skin burns caused by ultrasonic energy absorption in ribs.

Purpose of the Study:

To develop and validate a method for acoustic field focusing that spares ribs during HIFU treatment.
To mitigate the risk of skin burns associated with HIFU therapy for liver tumors.

Main Methods:

Utilized the Decomposition of the Time-Reversal Operator (DORT) method to create an excitation weight vector.
Applied a vector orthogonal to rib-focusing emissions to a transducer array.
Experimented with a linear transducer array and a chest phantom with immersed human ribs.

Main Results:

Successfully generated acoustic fields focused on a target while minimizing energy deposition on ribs.
Measured specific absorption rates demonstrating up to a 100-fold enhancement in the energy ratio at the focal point versus the ribs.
Validated the method's efficacy in sparing ribs using a needle hydrophone to measure acoustic fields.

Conclusions:

The DORT method effectively enables targeted ultrasound focusing, sparing ribs and reducing burn risks.
This technique significantly improves the safety profile of HIFU for liver tumor ablation.
The findings support the clinical translation of rib-sparing HIFU for enhanced patient safety.
