技术领域Technical field
本发明涉及超声成像技术领域，更具体地说，涉及一种超声成像设备的参数调整方法、装置、设备及计算机可读存储介质。The present invention relates to the field of ultrasonic imaging technology, and more particularly to a parameter adjustment method, apparatus, device and computer readable storage medium for an ultrasound imaging apparatus.
背景技术Background technique
目前，在使用超声设备检查使用者的过程中，往往是先是在大范围内先快速的移动探头搜索有无疑似病灶图像，一旦发现疑似病灶，会较缓慢的移动探头或者探头保持静止，然后手动或者使用机器的自动优化功能，调整参数优化图像，从而更清楚的观察和鉴别图像。在这个快速大范围搜索、然后小范围观察和鉴别的过程中，医生或者设备使用者对图像的成像速度和帧率的要求是不一样的。首先在大范围搜索过程中，医生更看重的是探头移动过程中图像的成像速度或者帧率等时间性能参数，而不是那么看重细节的图像质量等空间性能指标；而在发现疑似病灶之后需要停止探头移动，仔细的观察鉴别，这个时候医生就需要依赖的细节分辨率等空间性能指标，而不那么看重此时的成像帧率等时间性能指标。另外，对于观察人体体内的静止的器官和组织场景，和观察人体体内运动的组织和器官场景，二者对于时间性能和空间性能的侧重点是不相同的。而在常规超声成像系统中，由于成像原理的限制，很难同时满足较高的帧率和较高的图像质量，只能在参数预设时，要么只能侧重于帧率等时间性能，牺牲图像分辨率等空间性能；要么只能侧重于图像分辨率等空间性能，而牺牲图像帧率等时间新能。At present, in the process of using an ultrasonic device to inspect a user, it is often first to move the probe quickly in a wide range to search for a lesion image that is undoubtedly like a lesion. Once a suspected lesion is found, the moving probe or probe will be stationary slowly, and then manually Or use the machine's automatic optimization function to adjust the parameters to optimize the image to more clearly observe and identify the image. In this fast, wide-range search, then small-scale observation and identification, the requirements of the imaging speed and frame rate of the image by the doctor or device user are different. First of all, in the wide-scale search process, the doctors pay more attention to the time performance parameters such as the imaging speed or frame rate of the image during the movement of the probe, rather than the spatial performance indicators such as the image quality of the detail; and need to stop after the discovery of the suspected lesion. The probe moves and carefully observes the identification. At this time, the doctor needs to rely on the spatial performance indicators such as the detailed resolution, and does not value the time performance index such as the imaging frame rate at this time. In addition, for observing the static organs and tissue scenes in the human body, and observing the tissue and organ scenes of movement in the human body, the emphasis on time performance and spatial performance is different. In the conventional ultrasound imaging system, due to the limitation of the imaging principle, it is difficult to satisfy both the high frame rate and the high image quality, and only when the parameters are preset, or only focus on the time performance such as the frame rate, at the expense of Spatial performance such as image resolution; either focus on spatial performance such as image resolution, and sacrifice time and new energy such as image frame rate.
而且目前的超声成像系统是无法自动实时区分和鉴别出医生和操作者对于这两种场景对于时间性能和空间性能侧重点需求的区分，需要医生和操作者手动调节参数来使超声成像系统分别满足这两种场景对应的需求， 增加了医生的操作负担，进而降低了医生的检查效率和使用观感。Moreover, current ultrasound imaging systems are unable to automatically distinguish and identify in real time the distinction between doctors and operators for the temporal and spatial performance of these two scenarios. It is necessary for doctors and operators to manually adjust the parameters to satisfy the ultrasound imaging system. The requirements corresponding to these two scenarios increase the doctor's operational burden, which in turn reduces the doctor's inspection efficiency and the use of perception.

参见图1，本发明实施例提供的一种超声成像设备的参数调整方法，包括：Referring to FIG. 1 , a method for adjusting parameters of an ultrasound imaging apparatus according to an embodiment of the present invention includes:
S101、在超声成像设备的成像过程中，检测成像内容的变化程度信息；S101. In the imaging process of the ultrasound imaging apparatus, detecting information on the degree of change of the imaging content;
具体的，本方案中的成像内容的变化程度信息，可以是由于医生使用的探头是移动的，因此在探测静止/运动的器官和组织场景时，被探测区域会出现变化程度信息；或者，医生使用的探头是静止的，被探测的对象 是运动的组织和器官场景时，同样会出现变化程度信息。该变化程度信息表示被探测区域内的组织或者器官在成像过程中位置变化程度的信息，该信息可以用来判定是否需要对超声成像设备的参数进行调整，从而能够实现不同场景下对于成像的时间分辨性能和空间分辨性能的统一。Specifically, the information on the degree of change of the imaging content in the present solution may be that the probe used by the doctor is moving, so that when detecting the stationary/moving organ and tissue scene, the detected area may have a change degree information; or, the doctor The probe used is stationary, and the detected object is the moving tissue and organ scene, as well as the degree of change. The change degree information indicates information on the degree of change of the position of the tissue or organ in the detected area during the imaging process, and the information can be used to determine whether the parameters of the ultrasonic imaging device need to be adjusted, thereby enabling time for imaging in different scenarios. Unification of resolution performance and spatial resolution performance.
具体的，在本实施例中，在超声成像设备的成像过程中检测成像内容的变化程度信息可以包括：Specifically, in this embodiment, detecting the degree of change information of the imaging content in the imaging process of the ultrasound imaging apparatus may include:
在超声成像设备向被探测区域发射超声波束，并将所述被探测区域产生的回波进行波束合成生成回波信号的过程中，检测成像内容的变化程度信息；Detecting the degree of change of the imaged content during the process in which the ultrasonic imaging device transmits the ultrasonic beam to the detected area and beam-combines the echo generated by the detected area to generate an echo signal;
或者，在超声成像设备向被探测区域发射超声波束，将所述被探测区域产生的回波进行波束合成生成回波信号，并对所述回波信号进行处理生成所述被探测区域的图像信息过程中，检测成像内容的变化程度信息。Alternatively, the ultrasonic imaging device transmits an ultrasonic beam to the detected region, beam-combines the echo generated by the detected region to generate an echo signal, and processes the echo signal to generate image information of the detected region. In the process, information on the degree of change of the imaged content is detected.
具体的，超声成像设备的成像过程为现有技术内容，本方案在检测成像内容的变化程度信息时，并不局限于在成像过程中的哪一个具体的步骤进行检测，具体来说超声成像设备的成像过程包括如下步骤：Specifically, the imaging process of the ultrasound imaging device is prior art content, and the solution is not limited to which specific step in the imaging process to detect when the information of the degree of change of the imaging content is detected, specifically, the ultrasound imaging device The imaging process includes the following steps:
1)在超声成像设备向被探测区域发射超声波束，并将所述被探测区域产生的回波进行波束合成生成回波信号；1) transmitting, by the ultrasonic imaging device, an ultrasonic beam to the detected area, and beam-combining the echo generated by the detected area to generate an echo signal;
具体的，在步骤1)中，超声成像设备首先发射超声波束，对于被探测的组织或者散射子产生的回波进行波束合成，得到波束合成之后的能够代表一部分区域的发射回波信号的RF信号；重复进行发射、接收以及波束合成，最后得到能够覆盖整个图像区域的RF信号矩阵RFMatrix1。Specifically, in step 1), the ultrasound imaging apparatus first transmits an ultrasound beam, and performs beam synthesis on the echoes generated by the detected tissue or the scatterer to obtain an RF signal capable of representing a part of the region's transmitted echo signal after beam synthesis. Repeated transmission, reception, and beam synthesis, and finally an RF signal matrix RFMatrix1 capable of covering the entire image area.
2)对回波信号进行处理，生成最终的图像信息。2) Processing the echo signal to generate the final image information.
进一步，在对回波信号进行处理时，在本方案中可以通过两个处理步骤，具体包括：对RF信号矩阵进行解调，得到IQ信号IQMatrix1和回波包络信号IQEnvMatrix1；对解调之后的IQ信号或者包络信号进行滤波变采样率等操作，以及进行动态范围变换得到对应于灰度图像的数据矩阵GrayDataMatrix1。Further, when processing the echo signal, in the present scheme, two processing steps may be adopted, including: demodulating the RF signal matrix to obtain an IQ signal IQMatrix1 and an echo envelope signal IQEnvMatrix1; The IQ signal or the envelope signal performs operations such as filtering the sampling rate, and performs dynamic range conversion to obtain a data matrix GrayDataMatrix1 corresponding to the grayscale image.
通过重复上述两个步骤，可以得到另外一帧图像的RFMatrix2、IQMatrix2、IQEnvMatrix2和GrayDataMatrix2。By repeating the above two steps, RFMatrix2, IQMatrix2, IQEnvMatrix2, and GrayDataMatrix2 of another frame image can be obtained.
需要说明的是，在本方案对成像内容进行检测时，并不具体限定在哪个步骤进行检测，例如：可以是在步骤1)的RFMatrix1和RFMatrix2上进行，也可以是在步骤2)的IQMatrix1、IQMatrix2和IQEnvMatrix1、IQMatix2上，当然也可以是在步骤2)中GrayDataMatrix1和GrayDataMatrix2上进行。在进行检测时，可以通过典型的如进行二维自相关运算，找出相关系数最大时，互相关搜索的距离，该距离代表了被探测区域的运动距离。It should be noted that, when detecting the imaging content in the present solution, it is not specifically limited in which step to perform the detection, for example, it may be performed on RFMatrix1 and RFMatrix2 in step 1), or may be IQMatrix1 in step 2). IQMatrix2 and IQEnvMatrix1, IQMatix2, of course, can also be performed on GrayDataMatrix1 and GrayDataMatrix2 in step 2). When performing the detection, the distance of the cross-correlation search, which represents the moving distance of the detected area, can be found by performing a two-dimensional autocorrelation operation as usual.
本方案无论是在哪一个步骤检测成像内容的变化程度信息，其检测变化程度信息时均具体包括：检测成像内容的连续N帧图像之间的图像运动距离；其中，N为大于1的正整数。In any step of detecting the degree of change of the imaging content, the method for detecting the degree of change includes: detecting an image moving distance between consecutive N frames of the imaged content; wherein N is a positive integer greater than 1. .
可以理解的是，本方案中的成像内容与在哪个步骤进行检测有着密切联系，如果在步骤1)中进行检测，这时的成像内容即为RF信号矩阵，如果在步骤2)中进行检测，这时的成像内容为IQ信号和回波包络信号，或者数据矩阵，因此，在检测成像内容的变化程度信息之前，首先需要确定具体在成像过程的哪个步骤进行检测，从而才可以确定通过什么成像内容来计算变化程度信息。并且，本方案通过连续执行步骤1)和步骤2)，可以得到每一帧图像的在每个步骤的具体成像内容，因此，确定需要检测的步骤后，便可以通过在该步骤的连续预定帧图像的成像内容来计算变化程度信息；具体来说，本方案中的成像内容的变化程度信息，具体可以为成像内容的连续N帧图像之间的图像运动距离，也可以为连续N帧图像之间的变化差异程度，只要能表示出成像内容的变化程度信息即可，在本实施例中，以图像运动距离为例进行描述；并且，在检测成像内容的变化程度信息时，可以通过连续的N帧图像来确定该变化程度信息，这里的N的具体取值可以根据实际情况进行设定，例如：为了减小计算工作量，可以设置N为2，也就是说，可以检测每两帧图像之间的变化程度信息；为了提高检测的准确度，这时的N的取值可以大于2。It can be understood that the imaging content in this solution is closely related to the step at which the detection is performed. If the detection is performed in step 1), the imaging content at this time is the RF signal matrix, and if the detection is performed in step 2), The imaging content at this time is an IQ signal and an echo envelope signal, or a data matrix. Therefore, before detecting the degree of change of the imaging content, it is first necessary to determine which step of the imaging process is specifically performed, so as to determine what is passed. The content is imaged to calculate the degree of change information. Moreover, the present scheme can obtain the specific imaging content of each frame image at each step by continuously performing steps 1) and 2), and therefore, after determining the step to be detected, the continuous predetermined frame in the step can be passed. The image content of the image is used to calculate the degree of change information; specifically, the degree of change of the imaged content in the solution may be an image moving distance between successive N frames of the imaged content, or may be a continuous N frame image. In the present embodiment, the image movement distance is taken as an example for description; and in the case of detecting the change degree information of the image content, it may be continuous. The N frame image is used to determine the degree of change information. The specific value of N here can be set according to actual conditions. For example, in order to reduce the calculation workload, N can be set to 2, that is, each two frames can be detected. The degree of change between the two; in order to improve the accuracy of the detection, the value of N at this time can be greater than 2.
S102、利用所述变化程度信息，生成参数调整指令；S102. Generate a parameter adjustment instruction by using the change degree information.
具体的，本方案中的变化程度信息为表示被探测区域运动程度的信息，如果该变化程度信息表示成像内容的变化程度较大，则说明探头的移 动速度较大，和/或，被探测的组织或者器官的运动速度较大，这时生成的参数调整指令的目的为：通过对参数的调整，使在运动情况下生成的图像速率变高，从而适应运动场景；如果该变化程度信息表示成像内容的变化程度较小，则说明这时的探头移动较慢或者静止，并且，被探测的组织或者器官运动较慢或者是静止的，这时生成的参数调整指令的目的为：通过对参数的调整，使在静止情况下生成的图像分辨率较高，从而适应静止场景。Specifically, the degree of change information in the solution is information indicating the degree of motion of the detected area. If the degree of change information indicates that the degree of change of the imaged content is large, the moving speed of the probe is large, and/or the detected The movement speed of the tissue or organ is large, and the purpose of the parameter adjustment instruction generated at this time is to adjust the parameter to make the image rate generated under the motion condition become higher, thereby adapting to the motion scene; if the change degree information indicates imaging The degree of change of the content is small, indicating that the probe moves slowly or at rest, and the detected tissue or organ moves slowly or is stationary. At this time, the purpose of the parameter adjustment instruction generated is: Adjust to make the image generated in the static situation higher resolution, so as to adapt to the still scene.
S103、根据所述参数调整指令对所述超声成像设备的时间性能参数和/或空间性能参数进行调整。S103. Adjust a time performance parameter and/or a spatial performance parameter of the ultrasound imaging device according to the parameter adjustment instruction.
具体的，本方案中的时间性能参数为与成像速率相关的参数，例如：成像帧率、扫描帧率、超声波频率、解调频率等；本方案中的空间性能参数为与成像清晰度相关的参数，例如：每帧的扫查时间、帧相关系数、空间复合角度数、成像扫查线密度等。在变化程度较大时，需要侧重于帧率等时间性能参数，牺牲图像分辨率等空间性能参数；变化程度不大时，需要侧重于图像分辨率等空间性能参数，而牺牲图像帧率等时间性能参数。因此，在对参数进行调整时，需要根据具体的参数调整指令进行调整。Specifically, the time performance parameter in the solution is a parameter related to an imaging rate, such as an imaging frame rate, a scanning frame rate, an ultrasonic frequency, a demodulation frequency, etc.; the spatial performance parameter in the solution is related to imaging resolution. Parameters, such as: scan time per frame, frame correlation coefficient, spatial composite angle, imaging scan line density, etc. When the degree of change is large, it is necessary to focus on time performance parameters such as frame rate, and sacrifice spatial performance parameters such as image resolution; when the degree of change is small, it is necessary to focus on spatial performance parameters such as image resolution, and sacrifice image frame rate and other time. Performance parameters. Therefore, when adjusting the parameters, it is necessary to adjust according to the specific parameter adjustment instructions.
综上，可以看出，本方案能够自动鉴别医生对于在不同场景下对于超声成像系统的时间性能和空间性能不同需求，从而自动调节自身成像相关的图像参数，满足医生在不同场景下对于成像的时间性能和空间性能的不同需求。使得超声成像设备能够再观察快速运动图像内容时，能够自动提升图像帧率；而在观察缓慢变换甚至静止不动图像内容时能够自动增加图像分辨率、对比度和信噪比等二维图像性能指标。In summary, it can be seen that the solution can automatically identify different requirements for the time performance and spatial performance of the ultrasound imaging system in different scenarios, thereby automatically adjusting the image parameters related to the imaging of the self-image, and satisfying the doctor's imaging for different scenes. Different requirements for time performance and space performance. It enables the ultrasound imaging device to automatically increase the image frame rate when observing the fast moving image content, and automatically increases the image resolution, contrast and signal-to-noise ratio and other two-dimensional image performance indicators when observing slow-changing or even stationary image content. .
基于上述实施例，利用所述变化程度信息生成参数调整指令，包括：Based on the foregoing embodiment, generating the parameter adjustment instruction by using the change degree information includes:
判断所述图像运动距离与帧率增大阈值以及帧率减小阈值的关系；其中，所述帧率增大阈值大于所述帧率减小阈值；Determining a relationship between the image motion distance and a frame rate increase threshold and a frame rate decrease threshold; wherein the frame rate increase threshold is greater than the frame rate decrease threshold;
若所述图像运动距离大于所述帧率增大阈值，则生成的参数调整指令为以下参数调整指令中的任意一者：增大时间性能参数的参数值的调整指 令，增大时间性能参数的参数值并减小空间性能参数的参数值的调整指令；If the image motion distance is greater than the frame rate increase threshold, the generated parameter adjustment instruction is any one of the following parameter adjustment instructions: increasing an adjustment instruction of the parameter value of the time performance parameter, and increasing the time performance parameter An adjustment instruction that adjusts the parameter value and reduces the parameter value of the spatial performance parameter;
若所述图像运动距离小于所述帧率减小阈值，则生成的参数调整指令为以下参数调整指令中的任意一者：增大空间性能参数的参数值的调整指令，增大空间性能参数的参数值并减小时间性能参数的参数值的调整指令。If the image motion distance is less than the frame rate reduction threshold, the generated parameter adjustment instruction is any one of the following parameter adjustment instructions: increasing an adjustment instruction of the parameter value of the spatial performance parameter, and increasing the spatial performance parameter The parameter value and the adjustment instruction of the parameter value of the time performance parameter is reduced.
具体的，本方案通过连续执行步骤1)和步骤2)，可以得到每一帧图像的在每个步骤的具体成像内容，因此确定需要检测的步骤后，便可以通过该步骤在连续帧生成的成像内容来确定变化程度信息，从而生成参数调整指令；在本实施例中，以在步骤1)生成的两帧图像的成像内容为例对本方案进行描述。也就是说，在本实施例中的成像内容为RFMatrix1和RFMatrix2，则根据RFMatrix1和RFMatrix2的变化程度信息生成参数调整指令具体包括如下步骤：Specifically, the present scheme can obtain the specific imaging content of each frame image at each step by continuously performing steps 1) and 2), so after determining the step that needs to be detected, the step can be generated in consecutive frames. The content is determined to determine the degree of change information, thereby generating a parameter adjustment instruction; in the present embodiment, the present embodiment is described by taking the imaging content of the two frames of images generated in step 1) as an example. That is to say, the imaging content in the embodiment is RFMatrix1 and RFMatrix2, and the generating the parameter adjustment instruction according to the degree of change information of the RFMatrix1 and the RFMatrix2 specifically includes the following steps:
取RFMatrix1和RFMatrix2(假设矩阵大小为N*M)上，同样位置(i,j)的大小为n,m的邻域Sneibor1 i,j和Sneibor2 i,j，其中i<N，j<M。而横向纵向相关搜索范围为SL和SH，则二维互相关搜索公式为： Take RFMatrix1 and RFMatrix2 (assuming the matrix size is N*M), the same position (i, j) is n, m neighborhood Sneibor1 i, j and Sneibor2 i, j , where i < N, j < M. While the horizontal vertical correlation search range is SL and SH, the two-dimensional cross-correlation search formula is:
Figure PCTCN2018121956-appb-000001
Figure PCTCN2018121956-appb-000001
其中，
Figure PCTCN2018121956-appb-000002
among them,
Figure PCTCN2018121956-appb-000002
分别取不同的i和j执行上述步骤，最后得到整个图像区域的互相关结果矩阵，互相关结果矩阵中包含各点的运动距离计算结果和互相关系数。需要说明的是，在执行上述步骤时，可以对原数据进行插值之后，再进行二维互相关操作，以提升互相关搜索的精度。The above steps are performed by taking different i and j respectively, and finally the cross-correlation result matrix of the entire image region is obtained, and the cross-correlation result matrix includes the motion distance calculation result and the mutual relation number of each point. It should be noted that, when performing the above steps, the original data may be interpolated, and then the two-dimensional cross-correlation operation is performed to improve the accuracy of the cross-correlation search.
进一步，得到整个图像区域的互相关结果矩阵后，需要计算综合图像运动距离，计算方法有多种，在本方案中通过计算整个互相关结果矩阵的平均运动距离来进行确定，该图像运动距离Sdis计算公式如下所示：Further, after obtaining the cross-correlation result matrix of the entire image region, the integrated image motion distance needs to be calculated, and there are various calculation methods. In this solution, the average motion distance of the entire cross-correlation result matrix is calculated to determine the image motion distance Sdis. The calculation formula is as follows:
Figure PCTCN2018121956-appb-000003
Figure PCTCN2018121956-appb-000003
i∈[0,N]I∈[0,N]
j∈[0,M]J∈[0,M]
最终，计算出图像运动距离之后，便可以通过该图像运动距离Sdis与预先设定的阈值进行比较，该阈值用来对运动场景和静止场景进行区分；在本方案中，设置的阈值包括帧率增大阈值SfrmInc以及帧率减小阈值SfrmDec这两个阈值，也就是说，当计算得到综合图像运动距离Sdis大于SfrmInc时，表明图像需要提高成像帧率，降低每帧图像的扫查时间，降低帧相关系数和空间复合角度数等；Sdis小于SfrmDec时，表明需要降低图像帧率，提高图像二维质量，比如提升成像的帧相关系数，增加空间复合角度数，增加成像扫查线密度等。Finally, after calculating the image moving distance, the image moving distance Sdis can be compared with a preset threshold, which is used to distinguish between the moving scene and the still scene; in the present scheme, the set threshold includes the frame rate. Increasing the threshold SfrmInc and the frame rate reduction threshold SfrmDec, that is, when calculating the integrated image motion distance Sdis is greater than SfrmInc, indicating that the image needs to increase the imaging frame rate, reducing the scan time of each frame of the image, and reducing Frame correlation coefficient and spatial composite angle number; when Sdis is smaller than SfrmDec, it indicates that it is necessary to reduce the image frame rate and improve the image two-dimensional quality, such as increasing the frame correlation coefficient of imaging, increasing the number of spatial composite angles, and increasing the density of imaging scan lines.
需要说明的是，如果Sdis介于帧率增大阈值SfrmInc以及帧率减小阈值SfrmDec之间，这时可不对参数进行修改，也可以仅仅对时间性能参数或者空间性能参数进行修改；例如：确定帧率增大阈值SfrmInc以及帧率减小阈值SfrmDec之间的中间阈值，若Sdis介于帧率增大阈值SfrmInc与中间阈值之间，这时可以仅仅增加时间性能参数的参数值；若Sdis介于帧率减小阈值SfrmDec与中间阈值之间，这时可以仅仅增加空间性能参数的参数值；同样的，如果Sdis超过帧率增大阈值SfrmInc或者小于帧率减小阈值SfrmDec的程度在可允许的程度，这时也可以只增加时间性能参数的参数值或者只增加空间性能参数的参数值，也就是说，具体如果根据变化程度信息对参数进行调节，可以根据实际的情况来设定不同的参数调节规则，在本实施例中仅以上述论述为例，并不具体限定。It should be noted that if the Sdis is between the frame rate increase threshold SfrmInc and the frame rate decrease threshold SfrmDec, the parameters may not be modified at this time, or only the time performance parameter or the spatial performance parameter may be modified; for example, determining The intermediate threshold between the frame rate increase threshold SfrmInc and the frame rate decrease threshold SfrmDec. If Sdis is between the frame rate increase threshold SfrmInc and the intermediate threshold, then only the parameter value of the time performance parameter may be increased; Between the frame rate reduction threshold SfrmDec and the intermediate threshold, the parameter value of the spatial performance parameter may be increased at this time; likewise, if the Sdis exceeds the frame rate increase threshold SfrmInc or is less than the frame rate reduction threshold SfrmDec, the degree is allowed. To this extent, it is also possible to increase only the parameter values of the time performance parameters or only the parameter values of the spatial performance parameters, that is to say, if the parameters are adjusted according to the degree of change information, different ones can be set according to actual conditions. The parameter adjustment rule is only exemplified in the above description in the embodiment, and is not specifically limited.
可以理解的是，在本实施例中，仅仅以检测步骤1)的变化程度信息为例进行描述，在步骤2)中的对回波信号进行处理的过程中，同样可以获取变化程度信息，从而调整参数，在此并不具体赘述。并且，在本实施例中所述的根据成像内容的变化程度信息对参数进行自适应调节的功能，可以通过医生或者设备操作者控制其功能的打开或者关闭。It can be understood that, in this embodiment, only the change degree information of the detecting step 1) is taken as an example, and in the process of processing the echo signal in step 2), the change degree information can also be obtained, thereby Adjustment parameters are not described in detail here. Moreover, the function of adaptively adjusting the parameter according to the degree of change information of the imaged content described in the embodiment can be controlled by the doctor or the device operator to turn on or off the function.
