Description

Technical Field

[0001] The present application belongs to the field of telemedicine systems, and in particular, to a remote ultrasonic diagnosis system, method and device. Background Art

[0002] Telemedicine refers to the use of communication technology to provide medical services and diagnosis at a distance. Typically, in telemedicine technology, the scanned images obtained by ultrasound scanning can be transmitted over long distances, giving full play to the advantages of medical technology and medical equipment of large hospitals or specialized medical centers to provide remote diagnosis, treatment and consultation for the injured and sick in remote areas, islands or ships with poor medical conditions.

[0003] When implementing telemedicine technology, a stable and high-speed broadband network is crucial. Telemedicine technology requires real-time data transmission, including images, videos, sounds, etc. If the broadband speed is too slow, data transmission will be delayed, affecting the doctor's judgment and treatment of the condition. Therefore, for telemedicine technology, the broadband speed should have sufficient bandwidth to ensure the stability and accuracy of real-time data transmission.

[0004] However, due to the different bandwidth conditions in different regions, lossless compression of ultrasound scan images may not meet the bandwidth requirements, resulting in low efficiency of remote transmission. In order to improve transmission efficiency, the relevant images can only be compressed and transmitted. In the prior art, an image compression algorithm with a higher compression rate is usually directly selected to compress the ultrasound scan image, and the compressed image is transmitted remotely. Although the compressed image processed with a higher compression rate reduces the image size and ensures the transmission of the image, it may cause the lesion area in the ultrasound scan image to lose some detailed features, resulting in impaired image accuracy.

[0005] Therefore, a remote ultrasonic diagnosis system that can select real-time image compression mode according to network conditions is in urgent need of development. Summary of the invention

[0060] The present application is further described below in conjunction with the accompanying drawings.

[0061] In view of the problem in the prior art that, in order to ensure transmission efficiency, an image compression algorithm with a higher compression rate is directly selected to compress ultrasound scanning images, which causes image accuracy to be damaged, the present application provides a remote ultrasound diagnosis system, method and device that can ensure image quality while ensuring transmission efficiency.

[0062] Specific embodiment 1:

[0063] This application provides an embodiment:

[0064] like Figure 1 The present embodiment provides a real-time image compression mode selection module, comprising: a control unit 100, a test unit 200, a detection unit 300, a selection unit 400, a verification unit 500 and an adjustment unit 600; wherein the test unit 200 interacts with the control unit 100 for sending test data to the control unit 100; the detection unit 300 interacts with the control unit 100 for obtaining the delay of the current network according to the test data; the selection unit 400 interacts with the control unit 100 for determining a preliminary compression mode for the image to be transmitted according to the delay; the verification unit 500 interacts with the control unit 100 for obtaining the image quality of the image to be transmitted after being compressed using the preliminary compression mode; the adjustment unit 600 interacts with the control unit 100 for comparing the image quality with a preset image quality threshold to adjust the compression mode until the compressed image quality meets the preset image quality.

[0065] In this embodiment, the control unit 100 can be any programmable unit, such as a PLC or a single-chip microcomputer; the test unit 200 can be an ultrasonic probe; the ultrasonic probe is used to directly scan the sample, and the scanned sample can be an artificially prepared scanning sample to generate test data; the test unit 200 can also be constructed using software so that the control unit 100 can retrieve the original ultrasonic scanning image as test data.

[0066] Regarding the detection unit 300 and the control unit 100 described in this embodiment performing data interaction, the step of obtaining the delay of the current network according to the test data may be the following steps.

[0067] Network delay refers to the time required from one end of a network to the other end, and usually includes four parts: transmission delay, propagation delay, processing delay and queuing delay. Among them, transmission delay refers to the time required for data to be sent from the sender to the network; propagation delay refers to the time required for data to be transmitted on the network; processing delay refers to the time required for network equipment to process data; queuing delay refers to the time required for data to wait for processing in the cache queue of the network device; the total delay is equal to the sum of these four parts.

[0068] In this embodiment, the ultrasonic probe is used to directly scan the sample to generate an ultrasonic image, and then Traceroute is used to obtain the network delay. Traceroute is a tool for testing delay. In this embodiment, it uses a data packet consisting of an ultrasonic image and records the time required for each intermediate node through which the data packet passes from the source to the destination one by one to obtain the current network delay.

[0069] like Figure 2 , the determining of the preliminary compression mode for the image to be transmitted according to the delay includes: obtaining an existing commonly used compression mode and encapsulating it for easy calling; classifying the compression mode according to lossless compression and lossy compression to obtain a compression mode set; obtaining the compression rate of any compression mode in any of the compression mode sets; according to the compression rate corresponding to any of the compression modes, sorting the compression modes in sequence and numbering them in sequence to form a compression mode list; setting at least one delay threshold, corresponding the delay to the compression mode list, so that the higher the delay, the higher the corresponding compression rate, so as to determine the preliminary compression mode for the image to be transmitted.

[0070] In this embodiment, the compression mode set includes a lossless compression set and a lossy compression set; among them, for the lossless compression set, the generated video formats are: WAV, PCM, TTA, FLAC, AU, APE, TAK, WavPack; for the lossy compression set, the generated video formats are: mp3, Xvid, rmvb, wma, wmv; the method of generating the above-mentioned various video formats is the existing technology and will not be repeated in this article.

[0071] Since network delay greatly affects the transmission of images or videos, in this embodiment, the delay threshold is set, the delay is matched with the compression mode list, and according to the delay threshold, it is determined that the compression mode for the image to be transmitted belongs to a lossy compression mode set or a lossless compression mode set; according to the delay threshold, the corresponding compression mode is selected from the compression mode list corresponding to the lossy compression mode set or the lossless compression mode set.

[0072] In this embodiment, multiple delay thresholds are set and arranged in order from low to high delays; for example, the network delay thresholds are: 30ms, 100ms; if the network delay is less than 30ms, it means that the network status is very good, the network speed is very fast, and the delay is almost imperceptible; at this time, any video format in the lossless compression set is selected for transmission to meet the transmission requirements; or, according to the usage habits and applicable platforms, a commonly used video format is selected for transmission; if the network delay is greater than 30ms and less than 100ms, at this time, it means that the network status is general, the lossless compression mode cannot be used, and it is necessary to switch to the lossy compression set for selection; when selecting, in order to ensure the transmission rate, at this time, the compression ratio of various compression modes is first obtained, such as: the compression ratio of MP3 is 1:10, the compression ratio of Windows Media Audio (WMA) is 1:18; the compression ratio of Xvid is 1:1.2; the compression ratio of rmvb is 1:5; the compression ratio of wmv is 1:2; the compression mode list is as follows:

[0073]

[0074] Then, when choosing from the lossy compression set, use Windows Media Audio (WMA) format as the initial compression mode. At this time, the compression rate is very high, which greatly reduces the network pressure. If the network delay exceeds 100ms, it means that the network condition is poor and remote data transmission is not possible.

[0075] However, when using a compression mode with a high compression rate, the image may be blurred, and the effect of the video or image transmission is very poor. In order to solve this problem, in this embodiment, Figure 3 , the step of comparing the image quality with a preset image quality threshold to adjust the compression mode until the compressed image quality meets the preset image quality includes: setting an image quality threshold; comparing the image quality with the preset image quality threshold, and when the image quality is lower than the preset image quality threshold, selecting a compression mode with a lower compression rate than the preliminary compression mode as the adjusted compression mode until the compressed image quality meets the preset image quality. Further, when the image quality is lower than the preset image quality threshold, selecting a compression mode with a lower compression rate than the preliminary compression mode as the adjusted compression mode includes: obtaining a compression mode list corresponding to any compression mode set when the preliminary compression mode is obtained; when the image quality is lower than the preset image quality threshold, determining the sequence number in the compression mode list corresponding to the preliminary compression mode; respectively obtaining two compression modes corresponding to two adjacent sequence numbers; comparing the compression rates of the two compression modes, and selecting the compression mode with the lower compression rate as the adjusted compression mode.

[0076] In this embodiment, in order to prevent the problem of blurred images, it is necessary to adjust the initial compression mode, that is, adjust the compression mode from Windows Media Audio (WMA) to MP3 according to the compression mode list; at this time, compressed data such as pictures or videos are formed again; at this time, the image quality of the compressed data is obtained.

[0077] This embodiment uses the mean square error, a common evaluation index for measuring data distortion, to judge image quality;

[0078] The mean square error refers to the average value of the sum of the squares of the differences between the original image and the decompressed image pixel values. The calculation formula for the mean square error is defined as:

[0079] ;

[0080] Where M and N are the length and width of the image, f(x,y) is the pixel value of the original image at point (x,y), and g(x,y) is the pixel value of the decompressed image at point (x,y). The mean square error reflects the difference between the pixel values ​​of the two images. The smaller the error, the higher the quality of the decompressed image.

[0081] However, this evaluation index tends to be over-smoothed, resulting in a small mean square error value even if part of the edge structure of the image is removed. Therefore, it is necessary to introduce a structural similarity evaluation index that can reflect the edge similarity between the original image and the decompressed image.

[0082] The calculation formula of structural similarity is defined as follows:

[0083] ;

[0084] Among them, μ is the average gray value of the image. This parameter is used as the brightness prediction of the image to calculate the brightness difference between the original image and the decompressed image. σ is the standard deviation of the image grayscale. This parameter is used as the contrast prediction of the image to calculate the contrast difference between the two images. xy is the covariance of the two images and is used to calculate the structural similarity between the two images. c1, c2, and c3 are constants used to avoid instability when the denominator is close to 0, and N is the number of pixels in the image. Structural similarity can compare the brightness, contrast, and structure of two grayscale images.

[0085] ;

[0086] The formula for calculating structural similarity is a bounded function whose value range is [0,1]. The closer to 1, the more similar the two images are. Structural similarity makes up for the lack of edge structure similarity comparison and is more in line with the actual perception of human eyes when observing images. By combining the two parameters of mean square error and structural similarity, we can objectively measure the similarity between the original image and the decompressed image, and then evaluate the performance of the image compression algorithm.

[0087] Based on the above method, in this embodiment, the picture quality threshold can be set according to experience. If the picture quality formed by the preliminary compression mode is lower than the picture quality threshold, the preliminary compression mode needs to be adjusted, that is, the compression mode is adjusted from Windows Media Audio (WMA) to MP3 according to the compression mode list; at this time, compressed data such as pictures or videos are formed again; at this time, the image quality of the compressed data is obtained again and compared with the picture quality threshold until the compressed image quality meets the preset image quality; at this time, the selected compression mode is used as the final compression mode and involved in actual work.

[0088] Specific implementation II:

[0089] This application also provides an embodiment:

[0090] like Figure 4 A remote ultrasonic diagnostic system comprises: a real-time image compression mode selection module as described in specific embodiment I, at least one acquisition unit 1000, a processing module 2000, an output terminal 3000 and an auxiliary module 4000; the real-time image compression mode selection module as described in specific embodiment I is used to select a compression mode for an ultrasonic image to be transmitted; the acquisition unit 1000, such as an ultrasonic probe, is used to acquire the ultrasonic image to be transmitted in real time; the processing module 2000, such as a PC end, interacts with the real-time image compression mode selection module for data compression processing of the ultrasonic image to be transmitted using the compression mode selected by the real-time image compression mode selection module to obtain a compressed ultrasonic image; the output terminal 3000, such as a display, interacts with the processing module 2000 for data remotely receiving the compressed ultrasonic image through a network and displaying it to an operator; the auxiliary module 4000 interacts with the real-time image compression mode selection module for data adjustment of the compression mode list formed in the real-time image compression mode selection module according to the acquisition information of the ultrasonic image to be transmitted, so as to simplify the compression mode list in the real-time image compression mode selection module.

[0091] After selecting a compression mode through the real-time image compression mode selection module as described in specific embodiment I according to the network delay, the acquisition unit 1000 is used to acquire ultrasound images or videos; since the ultrasound video is composed of frames of images, it can be considered as frame-by-frame ultrasound images during transmission; then, in the processing module 2000, the acquired ultrasound image is compressed using the selected compression mode, and then sent to the output terminal 3000, i.e., the remote end, through the network to facilitate remote consultation.

[0092] However, it can be found in the specific embodiment I that when selecting from the lossy compression set, the format with the highest compression rate is used as the initial compression mode; if the image quality cannot meet the requirements, it is necessary to reselect the compression mode in sequence, resulting in a large amount of calculation and reduced work efficiency. In order to solve this problem, in this embodiment, Figure 5 , the compression mode list formed in the real-time image compression mode selection module is adjusted according to the acquisition information of the ultrasound image to be transmitted, including: acquiring information of the ultrasound image to be transmitted, such as ultrasound scanning site; comparing the information with a historical information library, obtaining a historical compression mode list according to the number of times used, and arranging the lists from the least number of times used according to the number of times used; obtaining the sum of the sequence number of any compression mode in the historical compression mode list and the sequence number in the compression mode list, and removing the compression mode with the smallest sum of the three sequence numbers according to the needs to obtain a streamlined compression mode list; using the streamlined compression mode list to obtain a preliminary compression mode in the real-time image compression mode selection module, and being able to quickly adjust the preliminary compression mode according to the image quality.

[0093] When in use, due to the differences in acoustic parameters such as acoustic impedance, density, and sound speed in various parts of the tissue, ultrasound will be backscattered (weak difference) or reflected (strong difference) in places where the acoustic parameters change during the propagation of the tissue. As a result, part of the sound wave is transmitted backward, and the remaining part continues to propagate deep into the tissue. Therefore, for scanning different parts, the complexity of the obtained ultrasound image is different due to the different scanning depths. For example, abdominal ultrasound diagnosis covers more organs and the imaging is more complicated; while for ultrasound examination of the thyroid gland, the imaging is relatively simple; therefore, for examinations of organs with more complex imaging, higher image quality is required. Therefore, in historical data, lossy compression modes with lower compression rates are mostly used; and for examinations of organs with simpler imaging, lossy compression modes with higher compression rates are mostly used in historical data. Therefore, after sorting according to historical data, the serial number of any compression mode in the historical compression mode list can be obtained, and then the serial number is added to the serial number in the compression mode list, and the compression mode with the smallest sum of 1, 2 or 3 serial numbers is removed according to needs to obtain a streamlined compression mode list. In this embodiment, the auxiliary module 4000 can be linked with the hospital's platform to obtain the ultrasound scan site according to the patient's name or consultation form; it can also be obtained by other means, such as scanning the QR code on the consultation form, etc., which will not be repeated in this article.

[0097] In this method, in order to ensure transmission efficiency, an image compression algorithm with a higher compression rate is directly selected to compress the ultrasonic scanning image, which causes the image accuracy to be damaged. The method described in this embodiment selects and determines the preliminary compression mode for the data to be transmitted according to the network delay; at the same time, in order to ensure the transmission quality, the data compressed by the preliminary compression mode is also verified, and the preliminary compression mode is adjusted according to the verification result until the image quality is met.
