Ultra-fast ultrasonic Doppler spinal cord micro-blood-flow imaging system

The invention belongs to the technical field of ultrasonic imaging of biomedicine and particularly relates to an ultra-fast ultrasonic Doppler spinal cord micro-blood-flow imaging system. The system disclosed by the invention comprises two parts, i.e., hardware and software, wherein the hardware part comprises an ultrasonic wave transmitting and receiving module and an experimental apparatus module; and the software part comprises modules of ultra-fast ultrasonic imaging, wave beam synthesizing, movement calibrating, clutter filtering, Doppler imaging, differencing and relevance analyzing. Firstly, an ultrasonic plane-wave transmitting and receiving control module is compiled based on an ultra-fast ultrasonic imaging technique and a multiangular plane-wave integrating imaging theory, and hardware units are controlled to transmit and receive ultrasonic waves by computer software; received echo data are processed, so as to finally obtain a Doppler blood flow image; and parameters such asvelocity and direction o
