What you need to know about focused ultrasound transducers

Views: 63     Author: Site Editor     Publish Time: 2024-05-31      Origin: Site

A focused ultrasound transducer is an advanced device that uses ultrasound energy for non-invasive treatment and diagnosis. By focusing ultrasound waves to a specific small area, this transducer can accurately deliver high energy without damaging surrounding tissues, and is used in a variety of medical applications, including tumor ablation, pain management, thrombolysis, and image enhancement.

Focused ultrasound technology combines the principles of acoustics and medical engineering to provide a safe, efficient, and repeatable treatment method that is constantly changing the face of modern medicine.


What is HIFU?

HIFU, short for High-Intensity Focused Ultrasound, is a medical technology that uses focused high-energy ultrasound waves to treat tumors and other diseases. HIFU technology focuses sound wave energy into a small area in the human body, generating high temperatures or mechanical effects, thereby destroying or killing abnormal cells in the tissue without damaging surrounding healthy tissue.


How HIFU works

  • Sound wave generation: The HIFU system generates high-frequency sound waves.

  • Sound wave propagation: These sound waves propagate through the skin and other tissues.

  • Sound wave focusing: The HIFU system uses special transducers to focus sound waves into a small target area.

  • Energy conversion: At the focus point, the energy of the sound waves is converted into heat or mechanical effects.

  • Therapeutic effects: High temperatures can destroy tumor cells, or the mechanical effects of sound waves can directly damage cell membranes, causing cell death.

Applications of HIFU

  • Facial Lifting: HIFU generates heat deep in the skin through focused ultrasound, stimulating the regeneration and remodeling of collagen, thereby lifting and tightening the facial skin.

  • Fat Burning: HIFU generates heat in fat tissue through high-energy focused ultrasound, causing fat cells to be damaged and gradually absorbed and metabolized by the body.

  • Tumor treatment: HIFU is commonly used to treat benign and malignant tumors, such as breast cancer, prostate cancer, uterine fibroids, etc. HIFU technology can precisely destroy tumor cells without surgery.

  • Pain management: HIFU can also be used to treat chronic pain, such as pain caused by bone tumors. By destroying pain-sensing nerve fibers, pain symptoms can be relieved.

  • Vascular disease treatment: HIFU can be used to treat vascular diseases such as hypertension and varicose veins.



  • Non-invasive: No surgical incision is required, reducing infection and recovery time.

  • Accuracy: Ability to accurately target and treat tumors without damaging surrounding healthy tissues.

  • Repeatability: The treatment process can be repeated and is suitable for multiple treatments.



  • Depth limitation: The penetration depth of ultrasound is limited, which affects the treatment effect on deep tissues.

  • Monitoring and control: Accurately controlling and monitoring temperature changes during treatment is a technical difficulty.

  • As an innovative medical technology, HIFU is gradually becoming an important means of tumor treatment and other disease treatments, and has broad prospects for future clinical practice.


How to choose a focused ultrasound transducer?

Application requirements: Determine what kind of application you plan to use the ultrasonic transducer in. Different applications may require different types of transducers, such as medical imaging, therapy, material processing, etc.


Frequency: The frequency of the ultrasonic transducer affects its performance in a specific application. Low-frequency transducers are suitable for deep tissue imaging and therapy, while high-frequency transducers are suitable for shallow tissue imaging and high-resolution imaging.

Focal length: The focal length determines the focal depth and diameter of the ultrasound. Selecting a transducer with the appropriate focal length ensures clear imaging or treatment effects in the required area.


Output power: For therapeutic applications, output power is an important consideration. Make sure the selected transducer can provide enough power to achieve the desired therapeutic effect.


Durability and reliability: The transducer should have sufficient durability and reliability to ensure stable operation over a long period of time and will not be damaged due to frequent use.
