Method and apparatus for gathering ultrasonic diagnosis system high-speed radio-frequency echo wave data

Abstract

The invention discloses a collecting method and a device of the high speed radio frequency echo of an ultrasonic diagnosis system, which comprises a field programmable gate array used for the logic realization of the control process in data collecting and transferring, a data buffer of high speed and large capacity used for buffering the data of high speed radio frequency echo, a program memory used for storing program instruction, a configuration file of the field programmable gate array and a system software memory used for storing configuration parameter of the field programmable gate array, a high speed USB controller used for being connected with the interface of a host computer and transferring the USB data at high speed. As the method and the device of the invention adopts the circuit structure based on FPGA, SDRAM, embedded system of soft nuclear processor, a USB controller, and data transfer between a USB collection card and the host computer, the collection and transfer of large capacity data can be realized, which meets the function of data collection and transfer of the ultrasonic diagnosis system.

Description

Technical field: [0001] The present invention relates to an ultrasonic diagnostic system and method, in particular to a high-speed radio frequency echo data acquisition method and device set on the ultrasonic diagnostic system for data acquisition and transmission with a host computer. technical background: [0002] The ultrasonic diagnostic system of the prior art is a new technology applied to medical diagnosis based on the development of electronics and the combination of radar technology and acoustic principles in the past 60 years. It can provide information about the normal and pathological conditions of the human body in real time. Important information on anatomy, functional status and hemodynamics. Because it is a non-invasive examination method, it has high diagnostic accuracy, relatively simple operation, and is economical. It has developed into one of the four major medical imaging techniques and is an essential clinical diagnostic method. [0003] Existing ultr...

Problems solved by technology

[0007] The existing PCI data acquisition card is generally set to be directly inserted into the PCI slot of the personal computer, and its digital signal input terminal is interconnected with the measured signal through a wire connection. This method will affect the quality of the measured signal, thereby affecting The normal operation of the ultrasonic diagnostic system; at the same time, a large number of wire connections will also cause the ultrasonic diagnostic system to fail to close the shell, because the traditional acquisition card requires a large number of lines to be inserted into the ultrasonic diagnostic system, which leads to the abnormality of the ultrasonic diagnostic system shell. installation that may affect the operation of the system

In addition, the PCI data acquisition card needs to be inserted into the chassis, which is inconvenient to connect and mobile acquisition
