Description

TECHNICAL FIELD

[0002] A medical ultrasonic imaging system scans a human body by using an ultrasonic beam, and obtains images of tissues and organs in the body by receiving echo signals of the tissues or organs and processing the data. Miniaturization and portability of the ultrasonic device are conducive to wider use of the ultrasonic device.

[0003] However, problems that do not exist or are not obvious on conventional large ultrasonic devices will be particularly prominent in the process of miniaturization. For example, a large amount of data during ultrasonic scanning makes it difficult for the miniaturized device to meet the operating capacity, and the system has poor real-time performance when switching parameters. On the other hand, it brings higher power consumption, making the device hot, especially for wireless small ultrasonic devices, which have short endurance and the bandwidth of wireless transmission cannot meet the demand of large data transmission.

[0004] As shown in the prior art ultrasonic scanning data, Figure 1 a complete scanning mode (S40) is included, and the complete scanning mode includes scanning of multiple surfaces (S41). Each scanning of the surface includes multiple groups of transmission (S42), which are grouped according to B mode (two-dimensional image mode), HAR mode (harmonic mode), CF mode (color Doppler mode), PW mode (pulse Doppler mode), TM mode (M mode), etc. Each group includes multiple scanning segments (S43, S44, S45).

Detailed Implementation

[0067] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0068] One embodiment of the present invention provides an ultrasound imaging system and its data transmission method that significantly reduces the amount of data. By using this data transmission method, the amount of data transmitted can be greatly reduced, thereby making the ultrasound imaging system more compact, with longer battery life, higher real-time system switching, and less heat generation during long-term operation.

[0069] The ultrasound imaging system 1000 of this embodiment is used for ultrasound scanning. The ultrasound imaging system 1000 includes a main unit 100 and an ultrasound probe 200. The main unit 100 sends information on how to scan, and the ultrasound probe 200 receives the scanning information and performs the scan. Taking human body scanning as an example, the propagation of ultrasound waves in the human body is used to obtain ultrasound characteristic information of human tissues and organ structures, obtain ultrasound echoes, and thus obtain ultrasound scan images. (See background technology and...) Figure 1 As shown, a complete ultrasound scan dataset includes multiple scan lines. This embodiment uses... Figure 2The compression method shown greatly reduces the amount of data of the multiple scan lines sent by the host 100. The storage order of the compression link is as shown in Figure 3 The compressed data format is as shown in Figure 4 .

[0070] Although the present application provides the method operation steps as described in the following embodiments or flowcharts, the execution order of the steps in the method is not limited to the execution order provided in the embodiments of the present application, based on conventional or non-creative labor, and there is no necessary causal relationship between the steps in terms of logic.

[0071] The data transmission method of the specific ultrasonic imaging system 1000 includes the following steps:

[0072] Step 101: Obtain the data of multiple scan lines arranged in order.

[0073] Here, the data of the scan lines can be obtained directly first, or the following steps can be used:

[0074] Obtain the original scan parameter table, which includes the original data of multiple scan lines arranged in order;

[0075] Compress the original data of each scan line to obtain the data of each scan line.

[0076] The host 100 can include a compression module. After the original data is compressed by the compression module, the amount of data is reduced, and the original data of each scan line is compressed to become multiple compressed data arranged in order.

[0077] In addition, the compression step of the compression module can be performed first, and then step 101 described above can be started. The compression can also be performed when the difference data of each line is calculated below, that is, the original data of each scan line is compressed first, and then the difference data is calculated, and then the next scan line is compressed.

[0078] For example, the background technology or Figure 1 , multiple scan lines are arranged in a certain order, in order of L0, L1, …… Lm, and the ultrasonic probe 200 scans column by column according to the order of the scan line arrangement. Figure 3 In the original scan parameter table S00, all scan lines of a frame are included, and the original data of the scan lines includes S01, S02, S03, etc. in order. The original data is compressed to obtain the data described above.

[0079] Step 102: Store the data of the nth scan line in the nth position of the reduced table.

[0080] The nth scan line is the first scan line, i.e., L0, and the first scan line is determined as a baseline, and the data thereof is directly saved.

[0081] In Figure 3 , the first scan line is completely stored in the start position of the reduced table, i.e., the position of the first line in the module S11.

[0082] Step 103: calculating difference data of the data of the (n+1)th scan line and the data of the nth scan line.

[0083] When n is 1, the (n+1)th scan line is the second scan line, and the difference data of the data of the second scan line and the data of the first scan line is calculated.

[0084] The difference data can be calculated by an exclusive or algorithm, and the difference data includes index information and difference content information, the index information includes an index number corresponding to a position where the content of the same position of the data of the (n+1)th scan line and the data of the nth scan line is different, and the difference content information includes a specific difference value of the position corresponding to the index number.

[0085] Since many bits of many scan lines are the same, especially between adjacent scan lines, there are only differences in some positions, and therefore, by the calculation method of the difference data, many repeated data can be omitted, and only the difference part is reserved, and specifically, the specific difference content can be determined by the index information and the difference content information.

[0086] For example, it is assumed that each scan line has 100 bits, and the difference between the nth scan line and the (n+1)th scan line is that the bit data of the 69th bit and the 72nd bit is different, and the bit data of the remaining 98 positions is the same. In the exclusive or algorithm, when two bit data are the same, the value obtained is 0, and when they are different, the value obtained is 1, that is, the values of the remaining 98 positions are not expressed, and only the 69th bit and the 72nd bit are recorded in the index information, and the specific difference of the 69th bit and the 72nd bit is recorded in the difference content information. Except for the data of the first scan line, all the scan lines are saved in the form of difference data, which greatly reduces the data amount.

[0087] Step 104: storing the difference data of the (n+1)th scan line in the nth+1 position of the reduced table, and storing the data of the (n+1)th scan line in the cache area.

[0088] In the reduced table, the data in the nth position is the complete data of the scan line, and the data after the nth+1 position is all difference data.

[0089] Step 105: Calculate the difference between the data of the next scan line and the data of the previous scan line.

[0090] The data from the (n+2)th scan line is compared with the data from the (n+1)th scan line, the data from the (n+3)th scan line is compared with the data from the (n+2)th scan line, and so on, until the difference calculation for all scan lines is completed. In other words, each line is compared with the previous adjacent scan line.

[0091] Step 106: Store the difference data in the position corresponding to the next scan line in the simplified table, and at the same time replace the data of the previous scan line in the cache with the data of the next scan line.

[0092] The difference between the (n+2)th scan line and the (n+1)th scan line is calculated. Although the data of the (n+1)th scan line has already been converted into difference data and stored in the simplified table, in step 104, the data of the (n+1)th scan line is stored in the buffer. Therefore, the data of the (n+2)th scan line is compared with the difference data of the (n+1)th scan line in the buffer. After the difference data of the (n+2)th scan line is calculated, the data of the (n+2)th scan line replaces the data of the (n+1)th scan line in the buffer. And so on, after calculating the difference data of any subsequent scan line, its data replaces the previous data in the buffer.

[0093] The original scanning parameter table includes several groups of modules, each group of modules including several scanning lines. These groups of modules correspond to one or more of the following: a two-dimensional image module (B module), a color Doppler module (CF module), a pulse Doppler module (PW module), a harmonic imaging module (HAR module), and an M module (TM module). The two-dimensional image module (B module) corresponds to the B mode in ultrasound, the color Doppler module (CF module) corresponds to the CF mode in ultrasound, the pulse Doppler module (PW module) corresponds to the PW mode in ultrasound, the harmonic imaging module (HAR module) corresponds to the HAR mode in ultrasound, and the M module corresponds to the M mode in ultrasound.

[0094] Continue with Figure 3 For example, module S00 corresponds to the background technology. Figure 1 A stream, or a frame, in an ultrasound image has a baseline. The scan lines in each frame are identical, the only difference being the scan time. Therefore, the host 100 only needs to send a simplified table S10 to the ultrasound probe 200 once.

[0095] Furthermore, such as Figure 4As shown in the figure, each scan line in the reduced table includes a head part, a data part and a tail part, each head part includes a fixed word head, each tail part includes an end check mark, the data part at the n-th position includes all data of the n-th scan line, and the data part at the rest positions includes difference data of the scan line corresponding to the position.

[0096] The ultrasonic imaging system 1000 can have a simplex mode, a duplex mode, a triplex mode, etc. In the simplex mode, the original scan parameter table includes one set of modules in the two-dimensional image module, the color Doppler module, the pulse Doppler module, the harmonic module and the M module. In the duplex mode, the original scan parameter table includes two different sets of modules in the two-dimensional image module, the color Doppler module, the pulse Doppler module, the harmonic module and the M module. In the triplex mode, the original scan parameter table includes three different sets of modules in the two-dimensional image module, the color Doppler module, the pulse Doppler module, the harmonic module and the M module, and so on.

[0097] In the simplex mode, the method described above is run.

[0098] Specifically, the original scan parameter table includes only one set of modules, which can be a two-dimensional image module (B module). In the duplex mode, the original scan parameter table includes two different sets of modules, which can be a two-dimensional image module (B module) and a color Doppler module (C module). Figure 3 In the duplex mode, the original data of all scan lines in the B module (S01) are compressed by the compression module, wherein the first scan line is stored in the reduced table S11, and the difference data of the remaining all scan lines is stored in the corresponding position in S11, and the compression processing calculation of S01 is completed.

[0099] In the duplex mode, the original scan parameter table includes a first module and a second module, the first module includes p scan lines, the second module includes q scan lines, and a total of p+q scan lines, and the specific method is as follows:

[0100] The difference data of the last scan line of the first module is stored in the p-th position of the reduced table, and the data of the last scan line of the first module is stored in the cache area;

[0101] The difference data of the first scan line of the second module and the data of the last scan line of the first module are calculated;

[0102] The difference data of the first scan line of the second module is stored in the p+1-th position of the reduced table, and the data of the last scan line of the first module in the cache area is replaced by the data of the first scan line of the second module.

[0103] Next, the next scan line in the second module is compared with the adjacent scan line in the second module, and the difference data is stored in the p+2-th position of the reduced table, and the data of the last scan line of the first module in the cache area is replaced by the data of the next scan line in the second module. Figure 3S12 stores the difference data, and sequentially completes the entry of the difference data of all scan lines in S02 into the simplified table.

[0104] In the three-mode, the original scan parameter table includes a first module, a second module and a third module, the first module includes p scan lines, the second module includes q scan lines, and the third module includes m scan lines, a total of p+q+m scan lines, and the specific method is as follows:

[0105] The difference data of the last scan line of the first module is stored in the pth position of the simplified table, and the data of the last scan line of the first module is stored in the cache area;

[0106] The difference data of the first scan line of the second module and the data of the last scan line of the first module is calculated;

[0107] The difference data of the first scan line of the second module is stored in the p+1th position of the simplified table, and the data of the last scan line of the first module and the data of the first scan line of the second module are stored in the cache area;

[0108] The difference data of the remaining scan lines in the second module is calculated and stored in the simplified table;

[0109] The difference data of the first scan line of the third module and the data of the last scan line of the first module is calculated;

[0110] The difference data of the first scan line of the third module is stored in the p+q+1th position of the simplified table, and the data of the last scan line of the first module in the cache area is replaced by the data of the first scan line of the third module;

[0111] The difference data of the remaining scan lines in the third module is calculated and stored in the simplified table, and the next scan line in the third module is compared with the adjacent scan line in the third module, and the difference data is stored in the simplified table. Figure 3 S13 stores the difference data, and sequentially completes the entry of the difference data of all scan lines in S03 into the simplified table.

[0112] The above steps are mainly the compression data steps in the host 100, and the decompression data process of the ultrasonic probe 200 will be discussed below. Figure 5 As shown in the figure, the hardware scan process of the decompression link is as follows: Figure 6 As shown in the figure, the scan timing diagram of the ultrasonic probe 200 when working is as follows: Figure 7 As shown in the figure.

[0113] The method includes the following steps:

[0114] obtaining a compact table of a plurality of scan lines arranged in sequence;

[0115] setting data of the nth scan line of the compact table as baseline data;

[0116] restoring difference data of the (n+1)th scan line to data of the (n+1)th scan line according to the baseline data;

[0117] restoring difference data of the (n+2)th scan line to data of the (n+2)th scan line according to the data of the (n+1)th scan line, and restoring data of all scan lines in this way.

[0118] Referring to FIG. 1, an ultrasound probe 200 is shown. Figure 6 Referring to FIG. 1, an ultrasound probe 200 is shown. Figure 6 The A region and the B region in FIG. 1 are two regions artificially divided in a processing unit 70 (FPGA) of the ultrasound probe 200. The baseline of the A region specifically refers to the nth scan line as described above. When n is 1, the baseline refers to the first scan line at the beginning of each scan. The first scan line is determined as the baseline. The line of the B region refers to other lines excluding the baseline at the beginning of the scan.

[0119] The processing unit 70 then stores the baseline in the scan information obtained completely in the A region, and stores other scan lines excluding the baseline in sequence in the B region. The data format of the scan line is shown in FIG. 2. Figure 4

[0120] When starting to work, referring to FIG. 3, and combining FIG. 1, when a trigger signal (TRIG) of the internal logic control of the processing unit 70 is at a low level, baseline data is written in the A region first, and the baseline data of the A region is read and stored in the B mode (Bmode) of the C region (CF mode working condition, then stored in the B mode and the CF mode at the same time). Figure 6 Figure 7 When the trigger signal (TRIG) of the internal logic control is at a high level, the data of the B mode (B mode) (CF mode working condition, then the B mode and the CF mode are read out at the same time) of the scan line is read out from the C region to each module, such as an AFE (analog front end module), a TX (transmitting module), and a BF (beam forming module).

[0121] When the trigger signal (TRIG) of the internal logic control is at a high level, the data of the B mode (B mode) (CF mode working condition, then the B mode and the CF mode are read out at the same time) of the scan line is read out from the C region to each module, such as an AFE (analog front end module), a TX (transmitting module), and a BF (beam forming module).

[0122] Next, other scan lines are read from the B region and parsed when the TRIG is at a low level:

[0123] ​​If it is B / PW / TM mode, the scan line is written into the B mode (B mode) corresponding RAM of the C area, the data of different parts in the B mode RAM is restored, and the scan line is read from the B mode RAM to each module (AFE, TX, and BF module) when the TRIG is high;

[0124] If it is CF mode, the scan line is written into the CF mode (CF mode) corresponding RAM of the C area, the data of different parts in the CF mode RAM is restored, and the scan line is read from the B mode RAM to each module (AFE, TX, and BF module) when the TRIG is high.

[0125] After one frame (one stream, or S00) scan is completed, the corresponding baseline content in the A area is read and written into the B mode RAM and the CF mode RAM in the C area, and the above steps are repeated to perform a new round of scanning.

[0126] The data transmission method of the ultrasonic imaging system 1000 described above can greatly reduce the data transmission amount, and further make the ultrasonic imaging system 1000 more miniaturized, have higher endurance, have higher real-time system switching, and have smaller heat generation during long-time work. When data is transmitted through a wireless network, the requirement for bandwidth transmission rate is reduced, so that more data can be processed in a miniaturized ultrasonic device, which is conducive to the better development of the miniaturized ultrasonic device.

[0127] In one embodiment, an ultrasonic imaging system 1000 is provided, which includes a host 100 and an ultrasonic probe 200. The host 100 and the ultrasonic probe 200 can be connected through a wired or wireless manner. Since the data amount is greatly reduced by using the data transmission method described above, the wireless connection is more preferred. The host 100 mainly completes the compression of ultrasonic scanning data, and the ultrasonic probe 200 is used for data decompression and human body scanning.
