Sequence configuration method and configuration system for ultrasonic equipment scanning repeated configuration lines

Abstract

The present invention provides a timing configuration method and configuration system for ultrasonic equipment to scan and repeatedly configure lines. The method includes: in the frozen state, sending and storing the configuration information of all scanning lines at one time; In the parameter parsing and configuration stage of the Nth scanning line, read the configuration information corresponding to the Nth scanning line from the cache, and judge whether the number of sending times reaches the preset parameter value. If so, scan the Nth scanning line At the same time, prepare for scanning N+1 scanning lines, if not, repeat the scanning of the Nth scanning line until the number of sending times of the Nth scanning line reaches the preset parameter value; the present invention Before scanning, preprocess the scanning line to obtain its configured sending times, and further adjust the scanning timing in real time according to the sending times carried by each scanning line, simplifying the configuration of scanning timing during the scanning process This method simplifies the scanning procedure and improves the scanning efficiency.

Description

technical field [0001] The invention belongs to the technical field of medical ultrasound, and mainly relates to a time sequence configuration method and a configuration system for ultrasonic equipment scanning repetitive configuration lines. Background technique [0002] With its unique real-time dynamic characteristics, the color ultrasonic diagnostic instrument has become one of the indispensable means of auxiliary diagnosis in modern medicine, and has become a criterion for judging certain diseases in clinical diagnosis. [0003] Such as figure 1 As shown in the working timing diagram of the ultrasound equipment, the Freeze signal is high to indicate the freezing stage, and low to indicate that the ultrasound equipment is in the scanning phase. Each trig signal represents the scanning of one-line data, and N line signals are combined to form an ultrasound Image; generally speaking, each scanning line has corresponding configuration information. During the working proces...

Problems solved by technology

[0006] However, based on product cost considerations, DDR is used as a memory for scanning configuration information and is also used for buffering echo data. In this way, after the falling edge of trig, the configuration information must be read at the fastest speed, otherwise, If you wait until the echo data arrives, it may affect the data reading and writing; correspondingly, you need to calculate the line number and length of the read scan line on the rising edge of trig, and read it immediately on the falling edge of trig; then, there is a time sequence One problem, in the prior art, it is only when the current trig is at a high level that it is known whether the line needs to be scanned repeatedly. At this time, the current configuration information has been parsed and sent. If you want to read it again, you must read it from the DDR. Read it again; if figure 2 As shown, at a certain time point of t3, line_num needs to be set to the read position of N+1, so that the timing design is cumbersome and error-prone

[0007] In the existing technical solutions, the biggest defect is that when it is analyzed that the current line configuration data needs to be read repeatedly, the configuration information has been delivered and the next scan is ready, and the line number information has jumped to the next line The scanning line is not conducive to finding the configuration information that needs to be sent repeatedly; in the prior art, the general solution is that if a scanning line needs to be repeatedly scanned, the configuration information of the scanning line needs to be stored in the DDR in advance Continuous storage multiple times, so a lot of waste of DDR storage resources
