The ultrasound imaging system 1000 of the present embodiment is used for performing ultrasound scanning, the ultrasound imaging system 1000 includes a host 100 and an ultrasound probe 200, the host 100 is used for sending information on how to scan, and the ultrasound probe 200 receives the scanning information to perform scanning. Taking scanning a human body as an example, ultrasonic wave characteristic information of human tissue and organ structure is obtained by using propagation of ultrasonic wave in the human body, ultrasonic echo is obtained, and an image of ultrasonic scanning is obtained. Referring to the background art and fig. 1, a set of complete ultrasound scanning data may include a plurality of scanning lines, in this embodiment, the compression method shown in fig. 2 is adopted, so that the data amount of the plurality of scanning lines sent by the host 100 is greatly reduced, the storage sequence of the compression link is shown in fig. 3, and the format of the compressed data is shown in fig. 4.
Although the present application provides method operational steps as described in the following embodiments or flowcharts, the method is not limited to the order of execution provided in the embodiments of the present application in which the steps are logically not necessarily causal, based on conventional or non-inventive labor.
The data transmission method of the ultrasound imaging system 1000 specifically includes the following steps:
step 101: and acquiring data of a plurality of scanning lines which are arranged in sequence.
Here, the data of the scan line may be directly acquired, or the following steps may be adopted:
acquiring an original scanning parameter table, wherein the original scanning parameter table comprises original data of a plurality of scanning lines which are arranged in sequence;
and compressing the original data of each scanning line to obtain the data of each scanning line.
The host 100 may include a compression module, where the data size of the original data is reduced after being compressed by the compression module, and the original data of each scan line is compressed to be a plurality of compressed data arranged in sequence.
In addition, the compression step of the compression module may be performed first, and then the above step 101 is started, or the compression may be performed when the difference data calculation is performed on each line in the following text, that is, the original data of each scan line is compressed first, then the difference data calculation is performed, and then the next scan line is compressed.
Taking the background art or fig. 1 as an example, a plurality of scanning lines are sequentially arranged in a certain order, namely L0, L1, and … … Lm, and the ultrasound probe 200 scans column by column in the order of the arrangement of the scanning lines. In fig. 3, the original scan parameter table S00 includes all scan lines of a frame of a scan, which include original data composed of S01, S02, S03, and so on, and the original data is compressed to obtain the data.
Step 102: and storing the data of the nth scanning line into the nth bit of the precise table.
The nth scanning line is the first scanning line, namely the L0, the first scanning line is determined as a base line, and the data of the first scanning line is directly stored.
In FIG. 3, the first scanline is stored in its entirety to the start of the fine profile, i.e., the location of the first line stored in block S11.
Step 103: and calculating difference data of the (n + 1) th scanning line and the data of the nth scanning line.
And when n is 1, the (n + 1) th scanning line is the second scanning line, and the difference data between the data of the second scanning line and the data of the 1 st scanning line is calculated.
The method for calculating the difference data can calculate the difference data between the data of the (n + 1) th scanning line and the data of the (n) th scanning line through an exclusive-or algorithm, wherein the difference data comprises index information and difference content information, the index information comprises an index number corresponding to a position where the content of the same position on the data of the (n + 1) th scanning line and the content of the same position on the data of the (n) th scanning line are different, and the difference content information comprises a specific difference value of the position corresponding to the index number.
Since many bits of many scanning lines are the same, especially, there is a difference only in the position of part between the adjacent scanning lines, so that many repeated data can be omitted by the calculation method of difference data, and only the part of difference is reserved, specifically, the specific difference content can be determined by the index information and the difference content information.
For example, assuming that each scan line has 100 bits, the nth scan line is different from the (n + 1) th scan line in that there is a difference between the 69 th bit and the 72 th bit, and the remaining 98 th bits have the same data, in the xor algorithm, when two bits have the same data, the obtained value is 0, and the value obtained when the two bits have the same data is not 1, that is, the values of the remaining 98 th bits have 0, and are not expressed, only the 69 th bit and the 72 th bit are recorded in the index information, and the difference between the specific contents of the 69 th bit and the 72 th bit is recorded in the difference content information. Except the data of the first scanning line, all the other scanning lines are stored in the form of difference data, so that the data volume is greatly reduced.
Step 104: and storing the difference data of the (n + 1) th scanning line into the (n + 1) th bit of the refined table, and simultaneously storing the data of the (n + 1) th scanning line into a buffer area.
The data except the nth bit in the precise profile is the complete data of the scanning line, and the data after the nth bit is all differential data from the (n + 1) th bit.
Step 105: and calculating difference data of the next scanning line and the data of the previous scanning line in sequence.
And performing difference calculation on the data of the (n + 2) th scanning line and the data of the (n + 1) th scanning line, performing difference calculation on the data of the (n + 3) th scanning line and the data of the (n + 2) th scanning line, and repeating the steps to complete the difference calculation of all the scanning lines, namely performing difference calculation on each line and the previous adjacent scanning line. In that
Step 106: and storing the difference data into the position corresponding to the next scanning line in the precise table, and replacing the data of the previous scanning line in the buffer area with the data of the next scanning line.
And (3) performing difference calculation on the n +2 th scanning line and the n +1 th scanning line, wherein although the data of the n +1 th scanning line is changed into difference data and is stored into a precise table, in step 104, the data of the n +1 th scanning line is stored in a cache region, so that the data of the n +2 th scanning line is compared with the data of the n +1 th scanning line in the cache region in a difference mode, after the difference data of the n +2 th scanning line is calculated, the data of the n +2 th scanning line is replaced by the data of the n +1 th scanning line in the cache region, and by analogy, after the difference data of any subsequent scanning line is calculated, the data of the scanning line is replaced by the data of the previous scanning line in the cache region.
