CMOS Chip for Invasive Ultrasound Imaging

  title={CMOS Chip for Invasive Ultrasound Imaging},
  author={C. B. William and Nicki Douglas},
Abstruct-A very small transmiffreceiver chip has been developed for use in an arterial ultrasonic imaging system. In this technique, a solid-state ultrasonic imaging head placed within a small medical catheter is used to provide high quality 360" images of arteries as small as 2 mm in diameter. Novel design and packaging techniques have been used to allow four easily testable 0.86 mm x 1.65 mm mixed-signal CMOS die to be placed on a multichip carrier within this 1.83 mm diameter imaging probe… CONTINUE READING
