Ultrasound System
Analog Front Ends | Pulsers and Switches | Embedded Processors – DSPs and SOCs
Medical and industrial systems use focal imaging techniques to achieve imaging performance far beyond the capabilities of a single-channel approach. Using an array of receivers, TI’s latest products for ultrasound can enable a high-definition image by time-shifting, scaling and intelligently summing echo energy, making it possible to focus on a single point in the scan region. By subsequently focusing on a different point, ultrasound systems can create substantially higher-quality images. Learn more by viewing the interactive ultrasound system block diagram or reading the ultrasound system design considerations.
In addition to advancements to improve image quality, semiconductor technology has also enabled ultrasound systems to become more compact, with cart-based ultrasound systems increasingly complemented by portable and handheld units. Learn more by viewing the portable ultrasound system block diagram. TI offers a range of ultrasound IC solutions that deliver the low power consumption and high performance that advanced ultrasound systems require.
