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...

Background:

Focused ultrasound (FUS) has emerged as a non-invasive therapeutic tool for tumor ablation, treating conditions like prostate cancer and uterine fibroids.
Despite advancements, clinical application faces challenges, particularly in brain targeting due to skull-induced distortions and motion artifacts in abdominal treatments.

Purpose of the Study:

To highlight the potential of novel ultrasonic therapy devices capable of operating in both Transmit and Receive modes.
To address the persistent challenges of skull distortion correction for brain targeting and motion artifact reduction in abdominal FUS treatments.

Main Methods:

Review of technological advancements in focused ultrasound therapy.
Emphasis on the dual Transmit and Receive mode capabilities of new ultrasonic devices.
Presentation of clinical results obtained from studies on monkeys and pigs.

Main Results:

The study emphasizes the potential of new FUS devices to overcome current limitations.
Clinical data from animal studies (monkeys and pigs) are presented to demonstrate efficacy.
The dual-mode functionality is shown to be crucial for addressing targeting and motion artifact issues.

Conclusions:

Novel focused ultrasound devices with Transmit and Receive modes offer promising solutions for overcoming clinical challenges in tumor ablation.
Further validation and clinical translation are needed, particularly for brain and abdominal applications.
The presented animal study results support the advancement of this technology for broader therapeutic use.
