Description

Technical Field

[0001] This invention relates to the field of ultrasound imaging equipment, and more particularly to a method for testing ultrasound imaging equipment, an ultrasound imaging device, and a system. Background Technology

[0002] Ultrasonic imaging equipment is a device that uses an ultrasonic probe to generate ultrasonic waves that irradiate the human body, and obtains visible images of the properties and structure of human tissues by receiving and processing the echoes that carry information about the characteristics of human tissues or structures.

[0003] Currently, most ultrasound imaging equipment manufacturers design individual board testing fixtures for incoming material inspection of different board components. These board components, after passing individual board testing, are then assembled into a complete machine for direct image performance testing. Furthermore, during long-term use of the ultrasound imaging equipment, some components may malfunction, leading to a decline in performance and consequently affecting the image quality. For example, aging of board components may affect the consistency of pulse signal transmission and reception, causing image problems such as dark channels. However, in existing technologies, it is often difficult to quickly locate the abnormal transceiver channel when problems occur; instead, it is necessary to disassemble the board components one by one and retest them individually to identify the abnormal transceiver channel. In the existing single-board testing process, the single-board testing fixtures are large in size, and each board component requires the development and maintenance of dedicated testing software, which is costly, inconvenient to carry, and inefficient, and cannot quickly locate problems. Furthermore, in the existing technology, the optimization of the image performance of ultrasonic imaging equipment is mostly done by adjusting parameters in real time, without intuitive and accurate data support, resulting in low efficiency and accuracy in optimization and debugging. Summary of the Invention

[0004] Therefore, it is necessary to provide an ultrasonic imaging device detection method, ultrasonic imaging device and system to address the above-mentioned technical problems, so as to solve the problems of low efficiency and inability to quickly locate abnormal transceiver channels of board components, and low efficiency and accuracy in optimizing and debugging the image performance of ultrasonic imaging devices.

[0005] A method for detecting an ultrasound imaging device, comprising:

[0006] After confirming that the self-test probe is plugged into the ultrasound imaging device, the set of ultrasound channels to be tested corresponding to the ultrasound imaging device is obtained. The set of ultrasound channels to be tested includes at least two groups of channels to be tested interconnected through the attenuation network module of the self-test probe. Each group of channels to be tested includes two ultrasound channels in the ultrasound imaging device combined according to a preset combination rule.

[0007] The attenuation network module is used to test the ultrasonic imaging signal of each of the channel groups under test, and to obtain the pulse information corresponding to each of the channel groups under test.

[0008] The channel fault detection result for each of the test channel groups is determined based on all the pulse information.

[0009] An ultrasound imaging device includes a controller for performing the ultrasound imaging device detection method described above.

[0010] An ultrasound system includes a self-test probe, an ultrasound probe, and the aforementioned ultrasound imaging device.

[0011] In this invention, after confirming the insertion of a self-test probe into the ultrasound imaging device, an attenuation network module within the self-test probe simulates human tissue as the object of ultrasound imaging, attenuating the pulse signal emitted by the ultrasound channel. The attenuated pulse signal is then received by another ultrasound channel, thereby enabling ultrasound imaging signal testing of each group of channels under test and acquiring their corresponding pulse information. Finally, the channel fault detection result for each group of channels under test is determined based on the pulse information corresponding to each group. This invention allows for accurate localization of specific abnormal faults in the channel groups under test on the circuit boards without disassembling the various circuit board components of the ultrasound imaging device. It also enables precise detection of the consistency and attenuation of the ultrasound channels in the ultrasound imaging device. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 and Figure 6 As shown, in one embodiment, a detection method for an ultrasound imaging device 100 is provided, comprising the following steps:

[0021] S100: After confirming that the self-test probe 200 is connected to the ultrasound imaging device 100, a set of ultrasound channels to be tested corresponding to the ultrasound imaging device 100 is acquired. This set includes at least two groups of channels to be tested interconnected by the attenuation network module 210 of the self-test probe 200. Each group of channels to be tested includes two ultrasound channels in the ultrasound imaging device 100 combined according to a preset combination rule. Understandably, the ultrasound imaging device 100 includes multiple ultrasound channels; for example, some ultrasound imaging devices have 64 ultrasound channels, while others have 128. In some embodiments, the preset combination rule includes combining multiple ultrasound channels in the set of channels to be tested one-to-one to form multiple groups of channels to be tested. Each group of channels to be tested includes two ultrasound channels. The two ultrasound channels in each group of channels to be tested are a transmitting channel and a receiving channel. The set of ultrasound channels to be tested refers to the collection of pairs of channels to be tested formed by combining all the ultrasound channels to be tested in the ultrasound imaging device 100. The set of ultrasound channels to be tested includes all ultrasound channels in the ultrasound imaging device 100. That is, each ultrasound channel must appear as either a transmitting or receiving channel in at least one group of ultrasound channels in the set. Furthermore, since each ultrasound channel can be combined with other ultrasound channels in pairs to form a group of ultrasound channels to be tested, and can function as either a transmitting or receiving channel, the groups of ultrasound channels to be tested cannot be repeated (i.e., it is not allowed for two ultrasound channels to appear in two different groups of ultrasound channels, and for their corresponding transmitting and receiving channels to have the same role). Therefore, the number of groups of ultrasound channels to be tested is less than or equal to 2×C(n,2), where: C is Combination, i.e., the number of combinations; n is the number of ultrasound channels; and C(n,2) is the number of all combinations of taking two ultrasound channels from n different ultrasound channels. Understandably, the above specific descriptions of the groups of ultrasound channels to be tested are all part of the preset combination rules.

[0022] Understandably, the self-test probe 200 includes an attenuation network module 210, which simulates human tissue and attenuates the pulse signal emitted by the ultrasound channel. After the self-test probe 200 is plugged into the ultrasound imaging device 100, the attenuation network module 210 interconnects the two ultrasound channels in each group of channels under test, facilitating subsequent ultrasound imaging signal testing of the interconnected groups of channels under test in the ultrasound imaging device 100. Understandably, the self-test probe 200 includes a test board, and the attenuation network module 210 is patch-connected to the test board of the self-test probe 200. The self-test probe 200 has a housing, and the test board and modules mounted on the test board are protected within the housing. The attenuation network module 210 can be a high-precision matching network composed of a symmetrical attenuation network. The two ultrasound channels of the ultrasound imaging device 100 are connected by a symmetrical attenuation network. One ultrasound channel acts as a transmitting channel, and the other as a receiving channel. The high-voltage pulse signal emitted by the transmitting channel is attenuated to the linear receiving range of the receiving device of the ultrasound imaging device 100 by the symmetrical attenuation network. The high-voltage pulse signal (i.e., the echo signal) after being attenuated by the symmetrical attenuation network is then transmitted to the controller 110 of the ultrasound imaging device 100 for processing through the receiving channel. At the same time, the controller 110 stores the relevant information of each transmitted and received pulse signal for analysis and calculation. The attenuation network module 210 can simulate the attenuation of high-voltage pulse signals by human tissue, so that the echo is attenuated to the linear receiving range. On the other hand, the symmetrical attenuation network allows the same ultrasound channel to act as both a transmitting and receiving channel, enabling different analyses by using it as a transmitting and receiving channel respectively. Furthermore, by testing the ultrasound imaging signal of each channel as a transmitting and receiving channel, the pulse information of each ultrasound channel can be obtained as a direct and accurate data source for image optimization.

[0023] In one embodiment, the self-test probe 200 is provided with a first identification code, and determining that the self-test probe 200 is plugged into the ultrasound imaging device 100 includes: acquiring the first identification code of the insertion device plugged into the ultrasound imaging device 100; when the first identification code of the insertion device is detected to be a preset self-test identification code, determining that the self-test probe 200 is plugged into the ultrasound imaging device 100.

[0024] S200, the ultrasound imaging signal of each of the test channel groups is tested through the attenuation network module 210 to obtain pulse information corresponding to each test channel group. In one embodiment, the test channel group includes two ultrasound channels: a transmitting channel and a receiving channel; the transmitting channel is interconnected with the receiving channel through the attenuation network module 210. It is understood that each ultrasound channel in the test channel group can both transmit and receive pulse signals, but cannot simultaneously function as either a transmitting or receiving channel (i.e., the same ultrasound channel cannot simultaneously transmit or receive pulse signals). In this embodiment, the ultrasound channel in the test channel group that transmits pulse signals is used as the transmitting channel, and another ultrasound channel interconnected with the transmitting channel through the attenuation network module 210 is used as the receiving channel to receive the pulse signal attenuated by the attenuation network module 210. It is understood that in another embodiment, the ultrasound channel that transmits pulse signals in this embodiment can also function as a receiving channel to receive the pulse signal transmitted by another ultrasound channel interconnected by the attenuation network module 210 as a transmitting channel and attenuated by the attenuation network module 210. In this step, after recognizing that the self-test probe 200 is plugged into the ultrasound imaging device 100, the controller 110 of the ultrasound imaging device 100 can automatically select the self-test probe 200 and directly start the self-test (i.e., perform an ultrasound imaging signal test). Alternatively, the operator can select "self-test probe 200" in the preset display interface of the ultrasound imaging device 100, and then click "start self-test" before the self-test of the self-test probe 200 begins. Understandably, before the self-test, the user's identity needs to be verified. That is, only specific personnel who can perform the self-test (such as R&D or customer service personnel) can perform the self-test. Therefore, the user's identity needs to be verified before the self-test. For example, the user's identity can be verified through facial recognition, voiceprint recognition, password verification, etc., and the self-test will only begin after the verification is correct.

[0025] Furthermore, such as Figure 2 As shown, in step S200, the step of performing ultrasound imaging signal testing on each of the test channel groups through the attenuation network module 210 to obtain pulse information corresponding to each test channel group includes:

[0026] S210, an initial pulse signal is transmitted to the attenuation network module 210 through the transmission channel of the channel group under test. In some embodiments, the initial pulse signal includes a high-voltage pulse signal.

[0027] S220: The initial pulse signal, attenuated by the attenuation network module 210 according to a preset ratio, is received through the receiving channel of the channel group under test, and the attenuated initial pulse signal is recorded as pulse information corresponding to the interconnected channel group under test. The preset ratio is determined based on the attenuation ratio of ultrasound waves to human tissue. In one embodiment, the preset ratio ranges from 20:1 to 60:1. Preferably, the preset ratio is 40:1. That is, the attenuation network module 210 attenuates the initial pulse signal emitted by the transmitting channel by a preset ratio by adjusting the amplitude of the transmitted pulse. The initial pulse is attenuated according to the preset ratio upon entering the attenuation network module 210.

[0028] S300, determine the channel fault detection result for each of the tested channel groups based on all the pulse information. The channel fault detection result may include the presence or absence of a fault. When the channel fault detection result indicates a fault, maintenance is required. Since the channel fault detection result for each tested channel group has been determined, the faulty tested channel group can be accurately located based on each of the channel fault detection results. Understandably, in some embodiments, the consistency information and channel attenuation information of the ultrasonic channels in each tested channel group can also be determined based on all the pulse information, thereby achieving accurate detection of the consistency and attenuation of the ultrasonic channels in the ultrasonic imaging device 100. The aforementioned consistency information and channel attenuation information can be included in the channel fault detection result or can exist as other information; this is not limited here.

[0029] The ultrasonic imaging device 100 testing method provided by this invention, after confirming that a self-test probe 200 is inserted into the ultrasonic imaging device 100, attenuation network module 210 set in the self-test probe 200 simulates human tissue as the object of ultrasonic imaging detection, attenuating the pulse signal emitted by the ultrasonic channel, and receiving the attenuated pulse signal through the attenuation network module 210 through another ultrasonic channel, thereby realizing ultrasonic imaging signal testing of each group of channels to be tested and obtaining the corresponding pulse information, and finally determining the channel fault detection result of each group of channels to be tested based on the pulse information corresponding to each group of channels to be tested. In this invention, the specific abnormal faults of the group of channels to be tested on the board components can be accurately located without disassembling the board components of the ultrasonic imaging device 100. This invention can also achieve accurate detection of the consistency and attenuation of the ultrasonic channels of the ultrasonic imaging device 100.

[0030] like Figure 3 As shown, in one embodiment, in step S300, determining the channel fault detection result of each of the tested channel groups based on all the pulse information includes:

[0031] S310, determine the test difference value of the pulse information corresponding to each of the test channel groups according to a preset difference statistical model. In one embodiment, the preset difference statistical model can be obtained by deep learning based on historical pulse information samples corresponding to the transmission and reception of pulse signals in the ultrasound channels of the same type of ultrasound imaging device 100, for example, by training a neural network model. The preset difference statistical model can also be a statistical model, which can first statistically determine the mean of all pulse information, then determine the difference value between each pulse information and the mean, and record the difference value as the test difference value.

[0032] S320, when the test difference value exceeds a preset difference range, the channel group to be tested corresponding to the test difference value exceeding the preset difference range is determined, and the channel fault detection result of the determined channel group to be tested is recorded as having a fault. The preset difference range can be set according to requirements, for example, the preset difference range can be set according to different imaging accuracies of the ultrasound imaging device 100. In some embodiments, the preset difference range includes a range fluctuating around zero, that is, the difference value within the preset difference range can include both positive and negative values. Preferably, the absolute values ​​of the minimum negative value and the maximum positive value of the preset difference range are equal. It can be understood that if the test difference value exceeds the preset difference range, it is considered that the channel group to be tested corresponding to the test difference value exceeding the preset difference range may have a fault (the fault includes, but is not limited to, damage, expiration of life, etc.), and the channel group to be tested may not be usable normally. At this time, it is necessary to send a notification to a professional maintenance party so that the professional maintenance party can check it according to the notification.

[0033] In some embodiments, the channel group to be tested includes a first channel group and a second channel group. Further, in step S100, before acquiring the set of ultrasound channels to be tested corresponding to the ultrasound imaging device 100, the following steps are included:

[0034] All ultrasound channels in the ultrasound imaging device 100 are acquired, and half of them are selected as transmission channels. The remaining half of the ultrasound channels are selected as reception channels. That is, the selected transmission and reception channels are paired one by one to form the first channel group in the channel group to be tested.

[0035] After pairing and combining each of the transmitting channels and the receiving channels one by one, a first channel group is generated. In this embodiment, all first channel groups contain all ultrasound channels in the set of ultrasound channels to be tested. Furthermore, each ultrasound channel appears only once in all first channel groups.

[0036] After recording all the transmitting channels in the first channel group as new receiving channels, and simultaneously recording all the receiving channels in the first channel group as new transmitting channels, each new receiving channel and each new transmitting channel is paired and combined to generate a second channel group. That is, the selected new transmitting channels and new receiving channels are paired one-to-one to form the second channel group in the test channel group. All second channel groups contain all ultrasound channels in the test ultrasound channel set, and each ultrasound channel appears only once in all second channel groups.

[0037] After recording all the first channel group and the second channel group as channel groups to be tested, a set of ultrasound channels to be tested corresponding to the ultrasound imaging device 100 is generated based on the channel groups to be tested. In the set of ultrasound channels to be tested, each ultrasound channel of the ultrasound imaging device 100 is included in two different sets of channel groups to be tested, serving as both a transmitting channel and a receiving channel. That is, in this embodiment, each ultrasound channel in the set of ultrasound channels to be tested appears once as a transmitting channel and once as a receiving channel in a first channel group and a second channel group, respectively. It can be understood that the above selection and pairing can be regarded as part of a preset combination rule. In one embodiment, if the set of ultrasound channels to be tested includes 64 ultrasound channels, and the 64 ultrasound channels are numbered from 0 to 63, then 0 can be paired with 32, 1 with 33, ..., 31 with 63, thus achieving one-to-one pairing of ultrasound channels (understandably, ultrasound channels 0 to 31 can be paired with ultrasound channels 32 to 63 according to other rules, or they can be randomly paired one-to-one, and the rules for selecting transmitting or receiving channels can also be set according to requirements, such as randomly selecting half). In the above pairing process, ultrasound channels 0 to 31 can be used as transmitting channels, and ultrasound channels 32 to 63 can be used as receiving channels to generate a first channel group (and ultrasound channels 0 to 31 can be used as receiving channels, and ultrasound channels 32 to 63 can be used as transmitting channels to generate a second channel group). Then, the attenuation network module 210 interconnects the two ultrasound channels in each successfully paired first channel group and second channel group, and records all first channel groups and second channel groups as test channel groups. Then, the set of ultrasound channels to be tested corresponding to the ultrasound imaging device 100 can be generated according to the test channel groups.

[0038] In one embodiment, neither the first channel group nor the second channel group contains two identical ultrasonic channels. That is, in this embodiment, the two ultrasonic channels in each test channel group will not be completely identical (but one may be identical; for example, one of the ultrasonic channels in two test channel groups may be the same, but this ultrasonic channel may be a receiving channel in one test channel group and a transmitting channel in the other). Figure 4 As shown, in step S320, after recording the channel fault detection result of the determined channel group under test as having a fault, the method further includes:

[0039] S321, the transmitting and receiving channels in the tested channel group that have faults are recorded as the target transmitting channel and the target receiving channel. That is, after determining that the channel fault detection result of the tested channel group is that there is a fault, it is necessary to determine which ultrasonic channel (or both of them) in the tested channel group is faulty. At this time, the two ultrasonic channels in the tested channel group are first identified as the target analysis objects, namely the target transmitting channel and the target receiving channel.

[0040] S322, the test channel group in the set of ultrasonic channels to be tested, in which the target transmitting channel is used as a receiving channel, is recorded as the first comparison channel group, and the test difference value corresponding to the first comparison channel group is recorded as the first comparison difference. That is, as explained in the above embodiments, each ultrasonic channel in the set of ultrasonic channels to be tested appears once as a transmitting channel and once as a receiving channel in a first channel group and a second channel group, respectively. Therefore, the test channel group in which the target transmitting channel is used as a receiving channel can be recorded as the first comparison channel group, and then its corresponding first comparison difference can be obtained to help determine whether the target transmitting channel and the target receiving channel are faulty.

[0041] S323, the test channel group in the set of ultrasonic channels to be tested, in which the target receiving channel serves as the transmitting channel, is recorded as the second comparison channel group, and the test difference value corresponding to the second comparison channel group is recorded as the second comparison difference. Similarly, since each ultrasonic channel in the set of ultrasonic channels to be tested appears once as a transmitting channel and once as a receiving channel in a first channel group and a second channel group respectively, the test channel group in the set of ultrasonic channels to be tested, in which the target receiving channel serves as the transmitting channel, can be recorded as the second comparison channel group, and then the corresponding second comparison difference can be obtained to help determine whether the target transmitting channel and the target receiving channel are faulty.

[0042] S324, based on the first comparison difference and the second comparison difference, determine the faulty channel from the two ultrasonic channels in the faulty test channel group. That is, in this embodiment, the faulty channel in the target transmission channel and the target reception channel can be further determined based on the first comparison difference and the second comparison difference.

[0043] In one specific embodiment, step S324, which involves determining the faulty channel from two ultrasonic channels in the faulty test channel group based on the first comparison difference and the second comparison difference, includes:

[0044] When the first comparison difference is within the preset difference range, the channel fault detection result of the first comparison channel group is confirmed to be fault-free, and the target receiving channel is recorded as a faulty channel. It can be understood that if the first comparison difference is within the preset difference range, it indicates that the first comparison channel group corresponding to the first comparison difference is fault-free, further indicating that the target transmitting channel, as a receiving channel, is fault-free in the first comparison channel group. Therefore, the target transmitting channel is fault-free. In summary, since the target transmitting channel in the faulty test channel group is fault-free, its corresponding target receiving channel is a faulty channel, and in this case, the target receiving channel can be recorded as a faulty channel. Understandably, if the first comparison difference exceeds the preset difference range, the first comparison channel group corresponding to the first comparison difference also has a fault, and it is also impossible to determine whether the target transmission channel serving as the receiving channel in the first comparison channel group has a fault. Therefore, referring to the content in the previous embodiment, the transmission channel in the faulty first comparison channel group is recorded as a new target transmission channel. Then, the test channel group where the new target transmission channel serves as the receiving channel is recorded as the third comparison channel group, and the test difference value corresponding to the third comparison channel group is recorded as the third comparison difference. Then, when the third comparison difference is within the preset difference range, the channel fault detection result of the third comparison channel group is confirmed to be fault-free. At this time, since the new target receiving channel corresponding to the third comparison channel group is a fault-free channel, the transmission channel in the first comparison channel group (i.e., the target transmission channel) is the faulty channel. Understandably, if the third comparison difference exceeds the preset difference range, the same analogy will be applied as in the above embodiment until the faulty channel is finally determined.

[0045] When the second comparison difference is within the preset difference range, the channel fault detection result of the second comparison channel group is confirmed to be fault-free, and the target transmission channel is recorded as a faulty channel. It can be understood that if the second comparison difference is within the preset difference range, it indicates that the second comparison channel group corresponding to the second comparison difference is fault-free, further indicating that the target receiving channel, as a transmission channel, is fault-free in the second comparison channel group. Therefore, the target receiving channel is fault-free. In summary, since the target receiving channel in the faulty test channel group is fault-free, the target transmission channel is a faulty channel, and in this case, the target transmission channel can be recorded as a faulty channel. Understandably, if the second comparison difference exceeds the preset difference range, the second comparison channel group corresponding to the second comparison difference also has a fault, and it is also impossible to determine whether the target receiving channel in the second comparison channel group, which serves as the transmission channel, has a fault. Therefore, referring to the previous embodiment, the receiving channel in the faulty second comparison channel group is recorded as a new target receiving channel. Then, the test channel group where the new target receiving channel serves as the transmission channel is recorded as the fourth comparison channel group, and the test difference value corresponding to the fourth comparison channel group is recorded as the fourth comparison difference. When the fourth comparison difference is within the preset difference range, the channel fault detection result of the fourth comparison channel group is confirmed to be fault-free. At this time, since the new target receiving channel corresponding to the fourth comparison channel group is a fault-free channel, the receiving channel in the second comparison channel group (i.e., the target receiving channel) is the faulty channel. Understandably, if the fourth comparison difference exceeds the preset difference range, the same reasoning will be applied as in the above embodiment until the faulty channel is finally determined.

[0046] Understandably, the faulty test channel group includes two ultrasonic channels. In this embodiment, the faulty channel is determined from the two ultrasonic channels in the faulty test channel group by the difference between the two ultrasonic channels in different test channel groups, thereby realizing the location of the specific faulty channel in the test channel group.

[0047] In one embodiment, after recording the channel fault detection result of the determined test channel group as having a fault, the method further includes:

[0048] The transmitting and receiving channels in the test channel group that have faults are recorded as the target transmitting channel and the target receiving channel. That is, after determining that the channel fault detection result of the test channel group is that there is a fault, it is necessary to determine which ultrasonic channel (or both of them have faults) in the test channel group has a fault. At this time, the two ultrasonic channels in the test channel group are first identified as the target analysis objects, namely the target transmitting channel and the target receiving channel.

[0049] Acquire a first waveform difference and / or a second waveform difference; the first waveform difference refers to the waveform difference information between the target transmission channel and other transmission channels adjacent to the target transmission channel; the second waveform difference refers to the waveform difference information between the target receiving channel and other receiving channels adjacent to the target receiving channel; wherein, it is understood that in this invention, it is possible to first acquire only one of the first waveform difference and the second waveform difference, or the first waveform difference and the second waveform difference can be acquired simultaneously. For example, if the first waveform difference is obtained first, the waveform amplitude, phase, and other information of one other transmission channel adjacent to the target transmission channel (or several consecutive adjacent transmission channels, such as 3 or 4; for example, if the test group of transmission channel 2 and receiving channel 34 fails, the waveform amplitude, phase, and other information of the other transmission channels will be compared with those of transmission channel 2 and its adjacent transmission channels 0 and 1) to obtain the waveform difference information between the target transmission channel and the other transmission channel, and record it as the first waveform difference. Similarly, if the second waveform difference is obtained first, the waveform amplitude, phase, and other information of one other receiving channel adjacent to the target receiving channel (or several consecutive adjacent receiving channels, such as 3 or 4) can be compared to obtain the waveform difference information between the target receiving channel and the other receiving channel, and record it as the second waveform difference.

[0050] When the first waveform difference exceeds a preset waveform difference range, the target transmitting channel is confirmed as a faulty channel; when the second waveform difference exceeds the preset waveform difference range, the target receiving channel is confirmed as a faulty channel. That is, in this embodiment, if the first waveform difference is first acquired, and the first waveform difference exceeds the preset waveform difference range (which can be set according to requirements), the target transmitting channel can be confirmed as a faulty channel. In this case, it is not necessary to acquire the second waveform difference to determine that the target transmitting channel is a faulty channel. However, if it is necessary to further determine whether the receiving channel is faulty, the second waveform difference will be acquired, and when the second waveform difference exceeds the preset waveform difference range, the target receiving channel will be confirmed as a faulty channel. Conversely, if the first waveform difference is within the preset waveform difference range, the target transmitting channel is confirmed as not a faulty channel; if the second waveform difference is within the preset waveform difference range, the target receiving channel is confirmed as not a faulty channel. Other embodiments can be determined similarly, and will not be elaborated further here.

[0051] In one embodiment, determining the channel fault detection result based on all the pulse information includes:

[0052] The test difference value of the pulse information corresponding to each of the test channel groups is determined according to a preset difference statistical model. In one embodiment, the preset difference statistical model can be obtained by deep learning based on historical pulse information samples corresponding to the transmission and reception of pulse signals in the ultrasound channels of the same type of ultrasound imaging device 100, for example, by training a neural network model. The preset difference statistical model can also be a statistical model, which can first statistically determine the mean of all pulse information, then determine the difference value between each pulse information and the mean, and record the difference value as the test difference value.

[0053] When the test difference value is within a preset difference range, the channel group under test corresponding to the test difference value within the preset difference range is identified, and the channel fault detection result of the identified channel group under test is recorded as fault-free. It is understood that the preset difference range can be set according to requirements; for example, the preset difference range can be set according to different imaging accuracies of the ultrasound imaging device 100 or according to different types of ultrasound probes used. If the test difference value is within the preset difference range, the channel group under test corresponding to the test difference value within the preset difference range is considered fault-free, but the channel group under test can be used normally.

[0054] In one embodiment, after recording the channel fault detection result of the determined test channel group as fault-free, the method further includes:

[0055] After all the channel fault detection results for the tested channel groups are found to be fault-free, the latest self-test time point is recorded. Specifically, if all the channel fault detection results for the tested channel groups are fault-free, it means that all ultrasound channels in the current ultrasound imaging device 100 are fault-free. In this case, no further self-testing is required within a preset self-test duration after the self-test by the self-test probe 200 is completed (the preset self-test duration can be set to six months or one year, etc., and is not limited here). The recorded latest self-test time point can be the time point when the current self-test is started, such as the time point when the self-test probe 200 is detected to be plugged into the ultrasound imaging device 100, or the time point when it is confirmed that all the channel fault detection results for the tested channel groups are fault-free.

[0056] The self-test time point is determined based on the latest self-test time point and the preset self-test duration, and a self-test reminder message is sent to a preset recipient at the self-test time point. That is, at the determined self-test time point, the specific personnel who need to perform the self-test can be directly notified to remind them to perform a self-test on the ultrasound imaging device 100 again. However, in this invention, only a self-test reminder message can be sent, and the ultrasound imaging device 100 is not required to perform a mandatory self-test.

[0057] In one embodiment, after recording the channel fault detection result of the determined test channel group as fault-free, the method further includes:

[0058] Based on the test difference values ​​corresponding to the fault-free test channel group and the preset ratio of the attenuation network module 210, signal compensation parameters corresponding to the ultrasound channels in the test channel group are generated. These parameters are then used to compensate for the consistency and attenuation of the ultrasound channels. It can be understood that if the test difference value is within the preset difference range, the test channel group corresponding to the test difference value within the preset difference range is considered fault-free, with only some consistency differences. However, the test channel group can be used normally. In this case, the consistency differences and attenuation of each test channel can be compensated using the test difference values ​​corresponding to each test channel group and the preset ratio of the attenuation network module 210 to meet the signal consistency requirements of each ultrasound channel. Understandably, in the test channel group, the transmitting channel transmits an initial pulse signal to the attenuation network module 210, which attenuates it. The ultrasonic imaging device 100 then receives the attenuated initial pulse signal through the receiving module. In this process, the entire circuit for transmitting pulse signals between the test channel group and the attenuation network module 210 includes attenuation from the attenuation network module 210, as well as channel attenuation from the transmitting and receiving channels. In this embodiment, compensation for the channel attenuation is required. Therefore, it is necessary to first determine the attenuation information corresponding to the channel attenuation based on the specific attenuation ratio of the attenuation network module 210 and the final test difference value. Then, based on this attenuation information, the corresponding signal compensation parameters (such as the apodization parameters used in ultrasonic beamforming) are accurately determined. This allows all fault-free ultrasonic channels to be compensated to the same level, ultimately achieving consistency among the ultrasonic channels. Understandably, if the attenuation information corresponding to the channel attenuation of the test channel group is zero, the signal compensation parameter used to compensate the test channel group can also be zero.

[0059] Understandably, in this invention, after the self-test of each ultrasound channel is completed, the ultrasound imaging device 100 will automatically save all test data and can automatically print a test report containing the test data when connected to a printer.

[0060] In one embodiment, after generating the signal compensation parameters corresponding to the ultrasound channels in the group of channels to be tested, the process includes:

[0061] After confirming that the ultrasound probe is connected to the ultrasound imaging device 100, signal compensation parameters corresponding to the ultrasound channel are obtained; human detection pulse signals are transmitted and received through the ultrasound channel and the ultrasound probe; at the same time, consistency and attenuation compensation are performed on the ultrasound channel according to the signal compensation parameters, and consistency and attenuation compensation are performed on the probe array elements of the ultrasound probe according to the received human detection pulse signals; an ultrasound image is generated and displayed based on the compensated human detection pulse signals. In this embodiment, it can be understood that after the self-test probe 200 confirms that all ultrasonic channels of the ultrasonic imaging device 100 are fault-free, and the signal compensation parameters associated with each ultrasonic channel are determined, and the ultrasonic imaging device 100 is put into use, the ultrasonic probe used for actual ultrasonic imaging can be inserted into the ultrasonic imaging device 100. At this time, after the ultrasonic probe is inserted into the ultrasonic imaging device 100, a human body detection pulse signal will be transmitted to the ultrasonic probe through the ultrasonic channel, and then the echo of the human body detection pulse signal will be received sequentially through the ultrasonic probe and the ultrasonic channel. In the above process, the ultrasonic channel used for transmitting or receiving the human body detection pulse signal can be compensated for in terms of consistency and attenuation by the signal compensation parameters. At the same time, although the ultrasonic channel can be compensated by the signal compensation parameters in the above process to achieve consistency between the ultrasonic channels of the ultrasonic imaging device 100, While the pulse signals emitted by each ultrasound channel of the ultrasound imaging device 100 are compensated by the signal compensation parameters, the human body detection pulse signals of the echoes may still differ. At this point, the center frequencies of each echo signal will not display as equal-frequency patterns, indicating that the probe array elements of the ultrasound probe corresponding to the abnormal echo signal are abnormal. In this case, if the abnormality of the probe array elements is minor (within the preset array element difference range), the probe array elements can be compensated by the array element compensation parameters. That is, the array element compensation parameters are determined based on the human body detection pulse signals received by the echoes (i.e., based on the human body detection pulse signals received by the echoes and the preset algorithm). Then, the probe array elements of the ultrasound probe are compensated for consistency and attenuation using the array element compensation parameters. Ultimately, through the dual compensation of the ultrasound channels and probe array elements, real-time optimization of ultrasound images is achieved. Figure 5 The diagram illustrates the process of compensating for the consistency and attenuation of probe array elements using array element compensation parameters. Specifically, after the ultrasound probe is connected to the ultrasound imaging device 100, the human body detection pulses emitted by each ultrasound channel of the ultrasound imaging device 100 are compensated by the aforementioned signal compensation parameters. The echo signals between the probe array elements of the ultrasound probes connected to each ultrasound channel also need to be compensated by the array element compensation parameters before the center frequency can be displayed. Figure 5 The topmost is the isofrequency graph.

[0062] Understandably, the array element compensation parameters can be stored in the ultrasonic probe's memory. When subsequent compensation of the probe elements using these parameters is needed, they can be retrieved from the memory without repeated determination, thus improving detection efficiency. Of course, the determination of the array element compensation parameters can be performed periodically, or when a difference is found in the human detection pulse signal echoed after compensation using the aforementioned parameters. Understandably, if the probe element abnormality exceeds the preset array element difference range, a probe element abnormality will be indicated, prompting replacement or repair of the ultrasonic probe. That is, the array element compensation parameters can only be adjusted within the preset array element difference range. If the range is exceeded, it is assumed that the ultrasonic probe's array elements may be damaged or have reached the end of their lifespan, rendering them unusable. In this case, further processing is required, and unlimited compensation is not permitted. This prevents unrestricted compensation even when the probe elements are damaged or their lifespan has expired, thus avoiding abnormal errors.

[0063] Understandably, the above signal compensation parameters can only be set within a preset compensation range and cannot exceed the preset compensation range (exceeding this preset compensation range indicates a fault in the ultrasound channel of the ultrasound imaging device 100, and compensation cannot be performed without limit). Understandably, the above preset compensation range can be adjusted according to the type of ultrasound probe.

[0064] In this invention, the array element compensation parameters are stored in the memory of the ultrasound probe and are used to compensate the probe array elements of the ultrasound probe. After the signal compensation parameters are generated, they are associated with the ultrasound channel and stored in the memory chip of the ultrasound imaging device 100 and are used to perform signal compensation processing and channel gain adjustment on the ultrasound channel associated with it. That is, the consistency and attenuation compensation of the human body detection pulse signals transmitted or received through the ultrasound channel and the ultrasound probe are performed according to the signal compensation parameters and the array element compensation parameters.

[0065] In one embodiment, the ultrasound probe is provided with a second identification code. Determining that the ultrasound probe is inserted into the ultrasound imaging device 100 includes: acquiring the second identification code of the insertion device inserted into the ultrasound imaging device 100; and determining that the ultrasound probe is inserted into the ultrasound imaging device 100 when the second identification code of the insertion device is detected to be a preset ultrasound imaging identification code. In this step, after recognizing that the ultrasound probe is inserted into the ultrasound imaging device 100, the controller 110 of the ultrasound imaging device 100 can automatically select the ultrasound probe and directly start ultrasound imaging detection (i.e., perform consistency and attenuation compensation on the human body detection pulse signal transmitted or received through the ultrasound channel; generate and display ultrasound images based on the compensated human body detection pulse signal). Alternatively, the operator can select "ultrasound probe" in the preset display interface of the ultrasound imaging device 100, and then click "start detection" before starting ultrasound imaging detection.

[0066] Understandably, the ultrasonic imaging device 100 is provided with a first connector for the self-test probe 200 to be plugged into and a second connector for the ultrasonic probe to be inserted into. Understandably, the first connector and the second connector can be the same connector, allowing either the self-test probe 200 or the ultrasonic probe to be plugged into. In this case, the connectors of the self-test probe 200 and the ultrasonic probe have the same shape and size. Thus, by redesigning the connector circuitry and integrating the detection code of the self-test probe 200 into the software, the self-test function of the transceiver channel of the self-test probe 200 can be realized, optimizing the overall self-test fixture design. The design is simple and compact, while significantly reducing the cost of the ultrasonic imaging device 100. Understandably, in this invention, the first connector and the second connector may be different connectors. The first connector is used to connect the self-test probe 200, and the second connector is used to connect the ultrasonic probe. In this case, whether the shape and size of the connectors of the self-test probe 200 and the ultrasonic probe are consistent depends on whether the specifications of the first connector and the second connector are consistent.

[0067] Furthermore, the first and second interfaces of the ultrasonic imaging device 100 are also provided with locking components. After the self-test probe 200 and the ultrasonic probe are respectively inserted into the first and second interfaces, they can be locked and positioned by the locking components.

[0068] In one embodiment, after determining that the self-test probe 200 is connected to the ultrasound imaging device 100 in step S100, the method further includes:

[0069] The ultrasound imaging device 100 sends control or status signals to the analog-to-digital converter module of the self-test probe 200 through its preset hardware circuitry. Understandably, the control or status signals include, but are not limited to, high-level signals or low-frequency signals. In one embodiment, the control or status signals are control signals or status signals, wherein the control signals include, but are not limited to, enable signals, mode switching signals, and button signals; the status signals include, but are not limited to, ultrasound probe power supply (e.g., 5V, 3.3V), reset signals, and low-frequency sine wave signals. Since the above control or status signals are all high or low level signals, or low-frequency signals with frequencies as low as tens of hertz, the analog-to-digital converter module of the self-test probe 200 is preferably a low-speed ADC (Analog-to-Digital Converter) chip. The ADC chip can be surface-mounted onto the test board of the self-test probe 200, and the signals between the two are transmitted through a board connector with the same definition. That is, according to the Nyquist sampling theorem, a sampling frequency ≥ 2 times the frequency of the sampled signal is sufficient to recover the sampled signal without distortion. Here, the sampled signal (control or status signal) is a low-frequency signal, so there is no need to use a high-speed ADC chip, saving costs. The aforementioned preset hardware circuit includes, but is not limited to, the storage circuit, indicator light driving circuit, high-precision matching network, ADC acquisition circuit, etc. in the ultrasound imaging device 100. When the ultrasound imaging device 100 can normally write or read data from the storage chip (corresponding to the storage circuit), the channel attenuation consistency is passed (corresponding to the high-precision matching network), the indicator light is normally on and off (corresponding to the indicator light driving circuit), and the ADC acquisition value is consistent with the preset value (corresponding to the ADC acquisition circuit), it indicates that the preset hardware circuit of the ultrasound imaging device 100 is normal. When any of these items cannot be performed normally, it indicates that there is an abnormality in the preset hardware circuit corresponding to the item that cannot be performed.

[0070] The system receives circuit test results corresponding to the preset hardware circuit from the analog-to-digital conversion module. These circuit test results are determined by the analog-to-digital conversion module based on the control or status signal and preset signal values. The preset signal values ​​include a first preset value corresponding to the control signal and a second preset value corresponding to the status signal. The expected values ​​are set according to the specific circuit connection design of the preset hardware circuit of the ultrasound imaging device 100. Understandably, if the control or status signal and the preset signal value are consistent, it indicates that the circuit test result of the corresponding preset hardware circuit is normal; if the control or status signal and the preset signal value are inconsistent, it indicates that the circuit test result of the corresponding preset hardware circuit is abnormal. This abnormality is usually due to an open circuit in the preset hardware circuit. In this case, an abnormality alert needs to be sent to the preset developer, prompting them to check and repair the preset hardware circuit.

[0071] In this invention, the original ultrasonic probe interface of the ultrasonic imaging device 100 can be reused, and the echo feedback data (the aforementioned pulse information) of the attenuation network module 210 can be combined with the basic function test and image optimization of the ultrasonic imaging device 100 to realize the whole-machine transceiver self-test and precise channel attenuation compensation of the ultrasonic imaging device 100; thereby realizing probe array element difference compensation (after the channel fault detection result is no fault, compensation is performed through signal compensation parameters), probe life indication (after the channel fault detection result is no fault, the magnitude of the test difference value is indicated), inter-channel crosstalk optimization (part of consistency compensation), whole-machine probe socket signal abnormality alarm (after obtaining all channel fault detection results and circuit test results, if the whole-machine probe socket signal is abnormal, an alarm is triggered), channel transmission / reception abnormality alarm (when the channel fault detection result is a fault, an abnormality alarm is triggered), etc.

[0072] In one embodiment, an ultrasound imaging device 100 is also provided, including a controller 110 for performing the ultrasound imaging device 100 detection method as described above. The execution function of the controller 110 corresponds one-to-one with the ultrasound imaging device 100 detection method in the above embodiment. Specific limitations of the controller 110 can be found in the limitations of the ultrasound imaging device 100 detection method described above, and will not be repeated here. Each submodule in the controller 110 can be implemented entirely or partially through software, hardware, or a combination thereof. Each submodule can be embedded in hardware or independently of the processor in the controller 110, or stored in software in the memory chip of the controller 110, so that the processor can call and execute the operations corresponding to each submodule.

[0073] like Figure 6As shown, in one embodiment, an ultrasound system is also provided, including a self-test probe 200, an ultrasound probe, and the aforementioned ultrasound imaging device 100. The ultrasound imaging device 100 is provided with a first connector for the self-test probe 200 to be plugged into and a second connector for the ultrasound probe to be inserted into. Understandably, the first connector and the second connector can be the same connector, which can be used to respectively adapt to the plugging of the self-test probe 200 or the ultrasound probe. In this case, the shape and size of the connectors of the self-test probe 200 and the ultrasound probe are consistent. Thus, based on the existing ultrasound imaging device 100, while keeping the original connectors for plugging into the ultrasound probe unchanged, by redesigning the connector circuit and then integrating the detection code of the self-test probe 200 into the software, the functional self-test of the transceiver channel of the self-test probe 200 can be realized. This optimizes the overall self-test tooling design, making it simple and compact, while significantly reducing the cost of the ultrasound imaging device 100. Understandably, in this invention, the first connector and the second connector may be different connectors. The first connector is used to connect the self-test probe 200, and the second connector is used to connect the ultrasonic probe. In this case, whether the shape and size of the connectors of the self-test probe 200 and the ultrasonic probe are consistent depends on whether the specifications of the first connector and the second connector are consistent.

[0074] Furthermore, the first and second interfaces of the ultrasonic imaging device 100 are also provided with locking components. After the self-test probe 200 and the ultrasonic probe are respectively inserted into the first and second interfaces, they can be locked and positioned by the locking components.

[0075] Understandably, the ultrasound imaging device 100 also includes a storage chip, which stores a preset self-test identification code for identifying the self-test probe 200 and a preset ultrasound imaging identification code for identifying the ultrasound probe. The specific identification process is described in the above embodiment and will not be repeated here.

[0076] In one embodiment, the self-test probe 200 includes a connector that plugs into the first interface, a test board connected to the connector, and a housing. The test board is connected to the ultrasound imaging device 100 via the connector. The housing can be identical to the housing of the ultrasound probe, thus eliminating the need for a separate housing mold, saving R&D costs, and allowing both to reuse the second interface already reserved for the ultrasound probe on the ultrasound imaging device 100. The self-test probe 200 of this invention is compact and portable, serving as a tool for R&D personnel to debug test boards and optimize image performance, and also convenient for customer service personnel to carry to the fault location site to troubleshoot and quickly locate the fault, significantly reducing testing costs.

[0077] In one embodiment, the test board includes a storage module 230 for storing the first identification code of the self-test probe 200, a digital-to-analog converter module 220 for detecting control or status signals of the ultrasound imaging device 100, and an attenuation network module 210 for detecting the ultrasound channel. The storage module 230, digital-to-analog converter module 220, and attenuation network module 210 are all surface-mounted to the test board. The specific functions of each module are as described in the above embodiment and will not be repeated here.
