摘要：
The invention relates to the field of medical instrumentation, in particular, to devices for non-invasive control of hemodynamics of cerebral blood flow and automatic registration of emboli. Provides portability by reducing the mass and size characteristics of the device with the implementation of the ability to display and transfer data. The device contains ultrasonic sensors 1, the outputs of which are made with the ability to connect to the inputs of the switch 2, the path 3 forming the sounding signals, consisting of a driver 4 excitation signals connected to the input of the pallet 5. The path 3 forming the sounding signals is connected through the output of the pulser 5 to the switch 2 The path 6 for receiving the echo signals contains a series-connected low-noise amplifier 7, an amplifier 8 with a time-varying gain, analog-to-digital converter (ADC) 9. The output of switch 2 is connected to the path 6 of receiving echo signals through the input of a low-noise amplifier 7. The path 6 of receiving echo signals through the output of analog-digital converter 9 is connected to the input of a digital signal processor (DSP) 10, having two-way communication with the universal processor 11, the output of which is connected to the connector 12 for connecting a removable memory card. A touch screen 13 and an information exchange unit 14 are connected to the universal processor unit 11, which includes the WiFi interface module 15 and / or the USB interface module 16. The device is equipped with a synchronizer 17 and a power supply 18, which is equipped with a battery 19. A path 3 for forming sounding signals, a digital signal processor 10 and a synchronizer 17 are implemented on a single FPGA chip. The digital signal processor 10 is made in the form of a software-hardware core, which consists of programmable FPGA elements and FPGA elements with rigid logic of operation. The digital signal processor 10 is made with the possibility of simultaneous implementation of the mod
