摘要：

The first generation Prototype of a portable, low-cost medical ultrasound device is described along with experimental results. The prototype system consists of a fully sampled 2D transducer array, sixteen custom receive circuitry chips multiplexed into two bandpass filter channels, and an onboard programmable logic device. A PC fitted with a commercially available data acquisition card is used for data collection and analysis. Beamforming is performed using the Direct-Sampled In-phase/Quadrature method. Pulse-echo images obtained with the prototype are presented and future work is discussed.
