 The SSA-380A PowerVision is the first fully digital ultrasound system for dedicated cardiovascular studies. PowerVision's Digital Continuous Beam Former (DCBF) converts the analog signal leaving the patient into digital form earlier than conventional analog/ digital hybrid ultrasound systems, which rely on the use of analog delay lines for signal summation. The result is a purer signal, with higher accuracy and repeatability. A fully digital architecture offers even more advantages: reduced noise and side lobes, improoved contrast and lateral resolution, speckle reduction,and enhanced Doppler sensitivity and greater dynamic range. The PowerVision "time-shares" the high-speed Continuous Beam Former to receive echoes from four directions simultaneously. Quad Signal Processing (QSP) empowers the system to receive up to four imaging lines of information, resulting in a two-time increase in frame rate, and two-time increase in line density. QSP provides more diagnostic information and greater accuracy, due to more sampling points (typically B/W-79 frames/second; Color Doppler-30 frames/second). Powervision provides the diagnostic power
for all of today's traditional Cardiology appli cations, including adult and pediatric
imaging with the system's Multifrequency capability allowing smart transducer imaging from
2.5-10MHz. Vascular imaging is made easy with the use of a Multifrequency 5/7.5/10MHz
linear transducer, which features independent beam steering and excellent low-flow
sensitivity from the utilization of the Advanced Velocity Range
Processing (AVRP) function. Additionally, a
comprehensive Stress Echo
