Fujifilm Sonosite has introduced what it says is the first 46 MHz ultrahigh-frequency transducer designed specifically for point-of-care ultrasound (POCUS).

The UHF46-20 transducer, compatible with the company’s Sonosite LX system, is intended for detailed superficial imaging and targets clinical areas where high-resolution visualization is essential, such as neonatology and rheumatology.

According to the Bothell, Washington-based manufacturer, the transducer provides a scan depth starting at 4 mm, allowing users to visualize anatomy just beneath the skin, including structures smaller than 1 mm. The technology is derived from Fujifilm VisualSonics’ UHF platform, which has traditionally been used in preclinical and research settings.
The company says the pairing of the UHF46-20 with the Sonosite LX offers the broadest frequency range currently available in a POCUS system. Use cases highlighted by the company include visualizing submillimeter vessels and nerves in neonatal care and identifying subclinical signs of inflammation in rheumatology exams.

Richard Fabian, president and CEO of Fujifilm Sonosite, said in a statement, “The UHF46-20 transducer, when paired with the Sonosite LX system, enables the largest frequency range of any point-of-care ultrasound system on the market today — addressing a long-standing challenge that current clinical ultrasound systems have been unable to overcome.”

While the UHF46-20 is currently exclusive to the Sonosite LX platform, the company is positioning it as a tool for improving procedural accuracy and diagnostic clarity at the bedside. Fujifilm also suggests the technology could support better first-attempt success rates during needle-based interventions, by enhancing anatomical visibility.

Fujifilm Sonosite is a subsidiary of Tokyo-based Fujifilm Holdings Corporation. More details on the UHF46-20 are available on the company’s website.
