USB 3.0-based color-ultrasound radiofrequency digital signal acquisition system

Abstract

The invention relates to the field of ultrasonic radiofrequency data acquisition and transmission, in particular to a USB 3.0-based color-ultrasound radiofrequency digital signal acquisition system which allows for high-speed acquisition and transmission of radiofrequency digital signals between a computer and a color-Doppler-ultrasound medical imaging system by USB 3.0 data transmission technology. The USB 3.0-based color-ultrasound radiofrequency digital signal acquisition system comprises a CPLD (complex programmable logic device) unit, an FIFO (first input first output) external buffer cache and a USB 3.0 interface chip. An output end of the FIFO external buffer cache is connected with an input interface of the USB 3.0 interface chip. The FIFO external buffer cache can transmit color ultrasound radiofrequency digital signals to the computer at high speed through the USB 3.0 interface chip under logic control of the CPLD unit, so that complete real-time transmission of the color ultrasound radiofrequency digital signals is achieved and transmission speed of the color ultrasound radiofrequency digital signals is also guaranteed. In addition, the USB 3.0-based color-ultrasound radiofrequency digital signal acquisition system has the advantages of the USB interface, such as high universality, connection convenience, and plug-and-play.

Description

technical field [0001] The present invention relates to the technical field of ultrasonic radio frequency data acquisition and transmission, in particular to a computer and a color Doppler ultrasonic medical imaging system using USB3.0 (provided by Intel, Microsoft, HP, Texas Instruments, NEC, ST-NXP and other enterprises) Published a new generation of USB standard) data transmission technology for high-speed acquisition and transmission of ultrasonic radio frequency digital signals, a color ultrasound radio frequency digital signal acquisition system based on USB3.0. Background technique [0002] Medical ultrasonic diagnostic equipment is generally welcomed by clinical units because it has advanced technical performance and can display tomographic images of different depths of the human body. It can not only image human soft tissues and organs, but also image blood flow according to the Doppler effect. . At present, although some high-end color ultrasound equipment importe...

AI Technical Summary

Problems solved by technology

In the prior art, the acquisition and transmission of ultrasonic radio frequency digital signals are mainly completed based on the PCI interface, but the color ultrasound radio frequency digital signal acquisition system designed based on the PCI interface has the following defects: first, it will be limited by the number of computer slots and interrupts resources, resulting in slower transmission speed; second, it is not easy to connect and install; third, radio frequency data transmission is easily affected by the electromagnetic environment in the chassis

The existence of these unavoidable defects has seriously inhibited the development of color Doppler ultrasound radio frequency digital signal acquisition system based on PCI bus
