| Abstract: | This article introduces a new blood flow measuring system based on PC. Its hardware consists of a personal computer, data acquisition board and a Doppler sensor unit. The quantitative measurement formula of blood flow velocity and BP neural network algorithm are applied in the system. The computation of blood flow velocity and error correction are realized by its software. Such a low cost system is universal and convenient for clinic applications. |
