Product Introduction
The Piezo Ceramic Transducer for Medical Imaging is the core components of ultrasound imaging systems, converting electrical energy into high-frequency mechanical waves that penetrate tissues and reflect diagnostic information. They are widely used in B-ultrasound, Doppler imaging, 3D/4D imaging, and portable diagnostic equipment.
Features
High-precision imaging performance
Our products use PZT-5H piezoelectric ceramic materials, with an electromechanical coupling coefficient of more than 0.65. With the precision-machined 1/4 wavelength matching layer, the ultrasonic signal conversion efficiency can be increased to 90%, and the axial resolution can reach 0.08mm, which is 40% higher than that of conventional transducers, meeting the needs of high-precision medical imaging diagnosis.
Long service life
Our equipment uses a titanium alloy shell with vacuum sealing technology. Tests in an 85% humidity environment show that the performance degradation does not exceed 5% after 10 years of continuous operation, and the service life is more than twice that of ordinary epoxy resin encapsulated products.
Customizable
The Piezo Ceramic Transducer for Medical Imaging support customized development within the frequency range of 1-20MHz. The number of array elements can be configured from 64 to 512 according to demand. At the same time, it provides a variety of arrangements such as annular, linear, and convex arrays to adapt to the imaging needs of different medical equipment.

FAQ
Q: What role does a piezo ceramic transducer play in medical imaging?
A: It is the core component in ultrasound imaging systems. It converts electrical pulses into high-frequency sound waves that travel through the body and then converts the reflected echoes back into electrical signals, which are used to construct medical images.
Q: Why is frequency range important in medical ultrasound transducers?
A: The operating frequency determines both the resolution and penetration depth of the ultrasound image. Higher frequencies (e.g., 7–15 MHz) provide better resolution for shallow tissues like breast or thyroid, while lower frequencies (1–5 MHz) penetrate deeper, making them suitable for abdominal or cardiac imaging.
Q: How does the design of the piezo ceramic transducer affect imaging quality?
A: Transducer arrays (linear, convex, or phased arrays) made of piezo ceramic elements allow dynamic focusing and beam steering, enhancing spatial resolution and image uniformity. Precision in element alignment and impedance matching directly impacts signal clarity and diagnostic accuracy.
Q: Can piezo ceramic transducers be used in minimally invasive imaging?
A: Yes. Miniaturized piezo ceramic elements (often <1 mm in size) are widely used in intravascular ultrasound (IVUS) and endoscopic ultrasound (EUS), enabling high-resolution imaging inside blood vessels or internal organs with minimal patient discomfort.
Q: What properties make piezo ceramic transducers suitable for clinical use?
A: They offer high electromechanical coupling efficiency, stable performance across temperature ranges, and strong signal sensitivity. Medical-grade ceramics are also biocompatible and chemically stable, ensuring long-term safety and reliability in diagnostic environments.
