Ultrasonic data packaging processing method and system

Abstract

The invention provides an ultrasonic data packaging processing method and configuration system, and the method comprises the steps: S1, configuring a register which is used for storing echo signal line length parameters, and the register comprises an analysis register and an execution register; S2, packaging the echo signal according to the line length parameter stored in the execution register ina state that the scanning signal and the echo data effective receiving signal are enabled at the same time; wherein each time the echo signal line length parameter analysis is completed, the analysisregister is updated; and after the current echo signal main body data is packaged, updating the execution register according to the echo signal line length parameter in the analysis register. According to the echo signal line length parameter updating method and device, the analysis register and the execution register which are both used for storing echo signal line length parameters are configured, and the two registers are updated according to the real-time data processing result, so that the problem of data line length loss or other parameter errors when transient delay of echo data occurscan be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical ultrasound, and mainly relates to a method and system for packaging and processing ultrasound data. Background technique [0002] Ultrasound imaging has become one of the most widely used clinical diagnostic tools because of its non-invasive, real-time, convenient operation, and low price. [0003] In an ultrasound system, each ultrasound image is composed of many scanning lines. After collecting the echo data sent back from the front end, the main control chip FPGA is required to package the data of each line, and add head and tail information to facilitate the PC to process and identify the data of each line. [0004] Such as figure 1 As shown, the Freeze signal is high to indicate the freezing stage, and low to indicate that the ultrasound equipment is in the scanning stage. Each trig signal represents the scanning of one-line data, and N line signals are combined to form an ultrasound image....

AI Technical Summary

Problems solved by technology

If, for the scanning line, the line length parameter is packed in the header information, then when the PC parses the line, it analyzes the header information and obtains that the line length of the scanning line is 2000, and the actual data length is 1900. In this way, the PC will think that the line transmission error

If the mode parameter or other parameters indicating the current line number are added at the end, it will cause the tail information to upload the parameters of the next line, which will also cause PC parsing errors
