摘　　要：提出了一种全数字化的B超成像系统解决方案,该系统具有16通道80阵元,采用高集成度的超声波发射与回波接收电路设计,基于FPGA和USB技术实现数字化超声成像.与传统模拟解决方案相比,本设计大大降低了系统的面积与功耗,有较高的分辨率与探测精度,具有更高的医学诊断价值,并且能够在社区医疗、大型赛事等方面得到推广.同时在此方案基础上进行了系统雏形的设计与实现,从系统的角度验证方案的可行性.A fully digitalized B-imaging system solution was presented in this paper, possessing 16 channels and 80 mapping array elements, designed with a high integration ultrasound transmitting and echo receiving circuit, being able digital ultrasound imaging based on FPGA and USB technologies. Compared with the traditional analog solutions, this solution can greatly reduce the area of the system and power consumption with better resolution and detection accuracy. It also can be adopted into the community medical service, large-scale sport events rescue and any other fields like this. Based on the presented solution, a prototype of the portable B-imaging system was made. The test result shows the feasibility of the system.
