Application-specific ICs have been traditionally used to support the high computational and data rate requirements in medical ultrasound systems, particularly in receive beamforming. Utilizing the previously developed efficient front-end algorithms, in this paper, we present a simple programmable computing architecture, consisting of a field-programmable gate array (FPGA) and a digital signal processor...
Traditionally, application-specific integrated circuits (ASICs) are used for supporting the computational and data rate requirements of medical ultrasound systems. Utilizing the previously-developed efficient front-end algorithms and the continuing advances in solid state devices, we developed a hybrid programmable architecture to support core ultrasound signal processing. With the advent of new-...
Ultrasound color Doppler imaging is widely used for real-time evaluation of blood flow in a user-specified region of interest. However, it is computationally expensive and burdensome for low-end ultrasound machines. In this paper, we have investigated the feasibility of performing color Doppler processing on a low-cost programmable architecture consisting of a field programmable gate array (FPGA)...
