DSPs and SoCs are specially designed single-chip digital microcomputers that process digitized electrical signals generated by electronic sensors (e.g., cameras, transducers, microphones, etc.) that will help to revolutionize the area of diagnostic ultrasound imaging. A diagnostic ultrasound imaging system generates and transmits acoustic waves and captures reflections that are then transformed into visual images. The signal processing on the received acoustic waves include interpolation, decimation, data filtering and reconstruction. Programmable DSPs and SOCs, with architectures designed for implementing complex mathematical algorithms in real-time, can efficiently address all the processing needs of such a system.
TI Digital Signal Processor (DSP) for Portable Ultrasound
Portable ultrasound systems are considered to be ultrasound systems that weigh around 10 lbs or less, and can run on batteries. They began to appear in the market place in the late 90s and have seen a remarkable growth in sales in the recent years. This growth has been a direct result of their applicability in areas such as ICUs, emergency medicine, regional anesthesia and battlefield.
