Medical imaging machines send complex signals into the body, then receive and process the signal reflections to develop an image of the internal body organs, blood flow or bone structure. Our high-performance signal-chain components drive imaging transducers that send and receive imaging signals to produce high-resolution images for improved diagnosis and treatment.
By transmitting acoustic energy into the body and receiving and processing the signal reflections, phased-array ultrasound systems can generate images of internal organs and structures, map blood flow and tissue motion, and provide highly accurate blood velocity information.
Historically, the large number of high-performance phased-array transmitters and receivers required to implement these imaging systems resulted in large and expensive cart-based implementations. Recently, advances in integration have empowered system designers to migrate to smaller, lower cost, and more portable imaging solutions with performance approaching that of the larger systems.
The challenge going forward is to continue to drive the integration of these solutions into smaller form factors, while increasing their performance and diagnostic capabilities.
This octal, three-level, digital pulser generates high-frequency, HV bipolar pulses (up to ±105V) from low-voltage control logic inputs for driving piezoelectric transducers in ultrasound systems.
This octal, high-voltage, transmit/receive (T/R) switches is based on a diode bridge topology and features . The amount of current in the diode bridges can be programmed through an SPI™ interface.
This fully-integrated octal ultrasound transceiver is optimized for high channel-count, high-performance portable and cart-based ultrasound systems. This transceiver allows the user to achieve high-end 2D and Doppler imaging capability using substantially less space and power.
