Ultrasonic probe (Transducer)

NDK has a medical manufacturing licence.

RoHS compliant

Ultrasonic probe is a very important sensor which generate acoustic signals and also detect returned signals. The performance and imaging quality of ultrasonic scanner are highly affected by the characteristic and the structure(piezoelectric material, matching layer and acoustic lens) of probe.
NDK has a wide range of probe portfolio for many applications and designs a customized(OEM) probe according to customer's request.
Moreover, the attestation of "ISO13485:2016" that is International Standard of the quality management system in medical devices acquired, and we will deliver secure, safe and high-quality product for medical devices.

Frequency and Resolution

High frequency probe can get the fine imaging with good resolution.
However the imaging of deep part will be smudgy due to wave length is short.
Meanwhile the imaging resolution of low frequency probe is low but ultrasonic wave can reach deep part. The scanning depth and resolution are mainly determined by the frequency of probe.

Frequency Resolution Penetration Possible scanning depth
High Fine Weak Shallow
Low Rough Strong Deep
