By Suresh Ram, National Semiconductor Corporation There is a rising demand for accessible medical care. The world population is rapidly growing and aging, increasing the cost of healthcare. Medical practitioners need small energy efficient and cost effective diagnostic devices. Portable diagnostic equipment that improve quality of healthcare in a cost effective manner are highly desirable.
National Semiconductor Corporation has unveiled an eight-channel ultrasound transmit/receive chipset specifically designed for portable ultrasound systems used in hospitals, clinics, ambulances and remote point-of-care facilities. The PowerWise® chipset’s innovative circuit architecture enables the design of both hand-carried and handheld units that deliver longer battery life and imaging performance comparable to larger console systems.
