[0026] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application.
[0027] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms "a", "said" and "the" used in this application are also intended to include plural forms, unless the context clearly indicates other meanings.
[0028] In order to enable those skilled in the art to better understand the technical solutions provided by the embodiments of the present application and to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application are further described in detail below in conjunction with the accompanying drawings.
[0029] See also Figure 1 , Figure 1 This is a flow chart of the method provided in the embodiment of the present application. The process is applied to an ultrasonic imaging system. In this embodiment, an ultrasonic self-test device and a signal self-test device are newly deployed in the existing ultrasonic imaging system.
[0030] As an embodiment, the ultrasound self-checking device and the signal self-checking device are arranged in the ultrasound probe of the ultrasound imaging system. The ultrasound imaging system also includes a host (also called ultrasound imaging system host).
[0031] As an embodiment, the ultrasonic self-test device, the signal self-test device, and the ultrasonic probe are deployed on the same central control mainboard, which is equivalent to being deployed on the same physical structure. Figure 2 shown.
[0032] As an embodiment, the ultrasound self-checking device and the signal self-checking device are deployed on other main boards independent of the main board where the ultrasound probe is located, which is not specifically limited in this embodiment.
[0033] In order to timely and accurately detect whether the ultrasonic probe has a fault, such as the minor defects described in the background technology or other serious defects, this embodiment sets the ultrasonic imaging system to work in a self-test mode. When the ultrasonic imaging system works in the set self-test mode, the following is performed: Figure 1 The process shown:
[0034] like Figure 1 As shown, the process may include the following steps:
[0035] Step 101: A control signal self-test device detects whether the channel connection between the ultrasonic probe and the ultrasonic self-test device is normal.
[0036] As an embodiment, in this step 101, based on a preconfigured period, the signal self-test device can be periodically controlled to detect whether the channel connection between the ultrasonic probe and the ultrasonic self-test device is normal, or the signal self-test device can be timed or externally triggered to detect whether the channel connection between the ultrasonic probe and the ultrasonic self-test device is normal.
[0037] Optionally, in this embodiment, the signal self-test device detection, the ultrasonic probe and the ultrasonic self-test device are bidirectionally connected, as shown in FIG. Figure 2 Under this premise, the signal self-test device detects whether the channel connection between the ultrasonic probe and the ultrasonic self-test device is normal. There are many ways to implement it. For example, the signal self-test device sends a reference signal. After the ultrasonic probe and the ultrasonic self-test device receive the reference signal, they will carry the local parameters related to the reference signal (such as the amplitude of the reference signal, the sensitivity of the received reference signal, whether the received reference signal is distorted, etc.) in the reference signal and continue to send it. Figure 2 On the premise that the links of the ultrasonic imaging system shown are normal, the final reference signal will be returned to the signal self-test device. After the signal self-test device receives the reference signal, it will rely on the parameters added by the ultrasonic probe and the ultrasonic self-test device carried by the reference signal to determine whether the channel connection between the ultrasonic probe and the ultrasonic self-test device is normal. For example, if at least one of the above parameters indicates that the reference signal is distorted and / or the amplitude value of the reference signal is less than the set amplitude value, and / or the receiving sensitivity of the reference signal is less than the set sensitivity, it is determined that the channel connection between the ultrasonic probe and the ultrasonic self-test device is abnormal, otherwise, it is determined that the channel connection between the ultrasonic probe and the ultrasonic self-test device is normal.
[0038] Step 102, when the signal self-test device detects that the channel connection between the ultrasonic probe and the ultrasonic self-test device is normal, the target detection data is obtained.
[0039] As an embodiment, the target detection data is data obtained by controlling the ultrasonic probe and the ultrasonic self-test device to enter the monitoring state. Here, the ultrasonic probe is prohibited from transmitting ultrasonic signals in the monitoring state. The ultrasonic self-test device monitors whether the ultrasonic probe receives ultrasonic signals in the monitoring state and generates the reference data of the ultrasonic probe in the non-working mode based on the ultrasonic signals received by the ultrasonic probe in the monitoring state. The reference data at this time is the above-mentioned target monitoring data. Finally, the target detection data described in step 102 is obtained when the signal self-test device detects that the channel connection between the ultrasonic probe and the ultrasonic self-test device is normal.
[0040] In this embodiment, after the reference data is obtained, it is checked whether the reference data and the configured reference data range meet the preset matching condition. If so, it is determined that the ultrasound probe is normal, otherwise, it is determined that the ultrasound probe is faulty.
[0041] On the premise that the ultrasonic probe is normal based on the reference data, the state of the ultrasonic probe can be further controlled to switch from the monitoring state to the self-test state and the ultrasonic self-test device can continue to be controlled to maintain the monitoring state. The ultrasonic probe is allowed to transmit ultrasonic signals in the self-test state. The ultrasonic self-test device monitors the ultrasonic signals emitted by the ultrasonic probe in the self-test state in the monitoring state and generates the self-test data of the ultrasonic probe in the working mode based on the monitored ultrasonic signals emitted by the ultrasonic probe in the self-test state. As another embodiment, the self-test data at this time can also be called target detection data. Finally, another implementation method of obtaining the target detection data in step 102 is realized.
[0042] Step 103: Detect whether the ultrasonic probe is faulty based on the target detection data.
[0043] In this embodiment, based on the target detection data, detecting whether the ultrasonic probe is faulty may include:
[0044] If the target detection data is the above-mentioned reference data, then check whether the reference data and the configured reference data range meet the preset matching condition. If so, determine that the ultrasonic probe is normal, otherwise, determine that the ultrasonic probe is faulty. If the target detection data is the above-mentioned self-test data, then check whether the self-test data and the configured self-test data range meet the preset matching condition. If so, determine that the ultrasonic probe is normal, otherwise, determine that the ultrasonic probe is faulty.
[0045] In this embodiment, whether it is the reference data or the self-test data, it may at least include: the frequency of the monitored ultrasonic signal and / or the ultrasonic signal echo information;
[0046] Table 1 below shows the self-test data range and self-test data by taking frequency as an example:
[0047]
[0048] Table 1
[0049] Applied to Table 1, if the frequency of the ultrasonic signal monitored in the reference data or the self-test data is within ±15% of the corresponding standard frequency (ie, the transmitting frequency), the ultrasonic probe is determined to be normal; otherwise, the ultrasonic probe is determined to be faulty.
[0050] It should be noted that, in this embodiment, as described above, the reference data or self-test data may also include ultrasonic signal echo information. For example, the ultrasonic signal echo information may be the echo duration (which is affected by the vibration time after electrical excitation and the communication rate). If the echo duration is within ±5% of the standard echo duration, it can be determined that the ultrasonic probe is normal, otherwise, it is determined that the ultrasonic probe is faulty. For another example: the ultrasonic signal echo information may be ultrasonic imaging data; if the monitored ultrasonic imaging data and the lossless image data stored in the flash have a similarity that meets a set threshold, such as higher than 70%, it is determined that the ultrasonic probe is normal, otherwise, it is determined that the ultrasonic probe is faulty.
[0051] The above is just an example to describe how to detect whether an ultrasonic probe is faulty, and is not intended to be limiting.
[0052] So far, completed Figure 1 The process shown.
[0053] pass Figure 1 It can be seen from the flow chart that in this embodiment, the ultrasonic self-test device detects the test data of the ultrasonic probe in different states to detect whether the ultrasonic probe is faulty (whether the hardware characteristics and software characteristics of the ultrasonic probe are faulty), and finally realizes the detection of the ultrasonic probe, so as to timely and accurately detect whether the ultrasonic probe has defects that affect the performance;
[0054] Furthermore, this embodiment detects whether the ultrasonic probe is faulty by detecting detection data of the ultrasonic probe in different states through the ultrasonic self-detection device, which may involve hardware characteristics and software characteristics of the ultrasonic probe and covers a wide range of detection content.
[0055] Furthermore, in the present embodiment, the ultrasonic probe and the ultrasonic self-test device and the signal self-test device are independent of each other. There is no phenomenon in which the detection process is hindered by damage to the ultrasonic probe. The abnormality of the ultrasonic probe can be detected with utmost precision, and the entire ultrasonic imaging system can be self-checked without the use of other professional auxiliary detection equipment.
