| Abstract: | To heighten the frame rate of ultrasound imaging system,the thesis focused on the dual beamformation technique and its hardware implementation was introduced.At first,its theoretical model was studied through both acoustic field modeling and computer simulation,and a modification scheme was proposed to solve the problems of distortion revealed by the simulation results.On this basis,a prototype of ultrasound imaging system with dual beams and synthetic aperture was designed and tested.The conclusion shows that the frame rate can be improved twice of the old. |
