Leveraging specialist expertise acquired through its system LSI business, Socionext has developed special-purpose LSIs for wireless ultrasound probe systems that are ultra-compact and lightweight, with low power consumption, and high image quality.
Having devised a variety of business patterns based around these special-purpose LSIs, Socionext supplies 32-ch and 64-ch wireless ultrasound solutions with the flexibility to meet the diverse needs of probe developers.
Business Pattern
Socionext supplies LSI chipsets for the development of high-performance wireless ultrasound probes. For customers with special requirements who require customization, we are also available for consultation on the development of PCBs or end-product probes that incorporate the chipset.
