摘要： A method and an apparatus for real-time calculation of receive focusing parameters for beamforming are provided. The apparatus is coupled to the signal input end of the receive beamforming module of an ultrasound imaging system as an independent accessory, including a first accumulator and a second accumulator for calculating a quantified focus coordinate (Fx,Fz); a distance determination circuit for calculating the distance between the quantified focus coordinate (Fx,Fz) and quantified coordinate (Elexj,Elezj) of the j-th array element of a probe; a third accumulator for accumulating the value of i*N/2; and a third summator for reading the output results of the third accumulator and the distance determination circuit, adding both output results up and outputting the added-up result as a reading address of echo data calculated in real time. With the present invention, the system memory resource required is reduced, the circuit is simpler, and the parameter loading is faster.
