Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Each step in this application is accomplished by ultrasonic probe or ultrasonic equipment, and the two cooperates the completion to ultrasonic probe's switching, and wherein, ultrasonic probe is responsible for detecting the motion and report the switching request to ultrasonic equipment, and ultrasonic equipment is used for deciding whether switch over after receiving the switching request to accomplish the probe and switch over. The probe processor may be implemented by a micro control unit (i.e., microcontroller Unit, MCU) or the like. The motion detection means is a means for detecting the moving state of the ultrasonic probe, and may be implemented by an inertial measurement unit (i.e., inertial Measurement Unit, IMU), an acceleration sensor, or the like. The probe processor and the motion detection component are configured on a board card of the ultrasonic probe, and are connected to the probe socket through a wire harness.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an ultrasonic probe switching system provided in an embodiment of the present application, which includes an ultrasonic probe (i.e. a probe) and an ultrasonic device (including a host and a display), wherein the ultrasonic probe includes a micro control unit MCU and an inertial measurement unit IMU, and at least a signal channel and a data channel are provided between a probe processor and a motion detection component. Wherein the signal channel is a channel for transmitting control signals and the like between the probe processor and the motion detection component, and can be realized through an EXIT channel (namely, an interrupt channel) between the MCU and the IMU. The data channel is a channel for transmitting data between the probe processor and the motion detection component, and can transmit data collected by each component in the probe, wherein the data can be realized through I2C (Inter-Integrated Circuit, two-wire serial bus).
The ultrasound device is connected to the ultrasound probe, and in particular, the ultrasound device may have a host processor therein, which may be communicatively connected to the probe processor, so as to receive a switching request sent by the ultrasound probe. After the ultrasonic equipment obtains the switching request, whether the ultrasonic probe is really required to be switched or not can be judged, namely whether the switching request is generated due to false touch or whether the current running state of the ultrasonic equipment is suitable for switching the ultrasonic probe or not. If the ultrasonic probe is determined to be required to be switched, the ultrasonic probe which sends the switching request is determined to be the currently used probe, and the switching of the ultrasonic probe is completed.
Specifically, referring to fig. 2 and fig. 3, fig. 2 is a timing chart of an ultrasonic probe switching method provided in an embodiment of the present application, and fig. 3 is a flowchart of an ultrasonic probe switching method performed by an ultrasonic probe provided in an embodiment of the present application. The method comprises the following steps:
s101: a signal path between the listening and motion detection components.
S103: and when the switching signal sent by the signal channel after the motion detection part detects the motion of the ultrasonic probe is monitored, sending a switching request to the ultrasonic equipment.
Steps S101 and S103 are executed by a probe processor in the ultrasound probe, in which the probe processor is added in the ultrasound probe, and the ultrasound probe is used to actively report the switching request. A signal path is provided between the probe processor and a motion detection component that is capable of detecting a change in the motion attitude of the probe, such as an acceleration change. When a user wants to use a certain currently unused ultrasonic probe, the probe can be removed from the probe holder, which can cause a change in the motion attitude of the ultrasonic probe, which can be detected by the motion detection means. Upon detecting this change, the motion detection component can actively send a switching signal (i.e., the INT signal, the interrupt signal, or referred to as an interrupt signal in FIG. 1) to the probe processor. The switching signal is a signal indicating that the motion detection means detects a change in the motion posture of the ultrasonic probe to which it belongs.
Specifically, the motion detection unit may compare the acquired motion data with data in a register (may be that the ultrasonic probe is in a stationary state or the motion amplitude is smaller than gesture data corresponding to a set amplitude threshold value), and if the acquired motion data and the gesture data are inconsistent, determine that movement occurs, and send a switching signal to the probe processor. After the probe sensor monitors the switching signal, the probe sensor sends a switching request to the ultrasonic equipment. A switching request refers to a request indicating that the ultrasonic probe to which the switching request belongs is switched to a probe currently in use, and a specific form thereof is not limited, for example, in an embodiment, a switching signal may be directly used as the switching request; alternatively, the switching signal may be encapsulated, and the switching request may be obtained after the encapsulation is completed. And actively reporting a switching request to the ultrasonic equipment.
By the mode of actively reporting the switching request, the ultrasonic equipment can scan the motion detection component in the probe without polling to identify the motion state of the motion detection component, so that the burden of the ultrasonic equipment is reduced, and the defect of reduced imaging frame frequency caused by polling scanning of the ultrasonic equipment in an imaging gap is avoided. Meanwhile, the problem that the probe switching cannot be completed due to the fact that the probe is not scanned in time due to the fact that the motion state of some probes is changed due to the fact that the polling signals sent out during polling scanning cause interference to an ultrasonic image generated by ultrasonic equipment and the problem that the probe switching cannot be completed due to the fact that the scanning speed is low during polling scanning is avoided.
In addition, since the ultrasonic device needs to determine the motion gesture of the ultrasonic probe when executing certain services, the probe movement data refers to the data which can indicate the motion gesture of the ultrasonic probe and is acquired by the motion detection component, and the specific type of the data is not limited, and can include acceleration, angular velocity, three-dimensional space gesture information, position information and the like. Ultrasound devices typically do not directly use probe movement data, but rather require processing of the probe movement data to obtain and use the processing results. In order to reduce the burden of the ultrasonic equipment, the probe processor can be used for processing the probe movement data, and the processed target movement data can be sent to the ultrasonic equipment. Specifically, the probe processor acquires probe movement data sent by the motion detection component through a data channel (for example, an I2C channel in fig. 1) between the probe processor and the motion detection component, and preprocesses the probe movement data to obtain target movement data. It is understood that the probe movement data and the target movement data may be multiple items, and the specific type of the target movement data is not limited, so that the correspondence between the probe movement data and the target movement data, and the specific processing mode of the preprocessing are not limited. For example, an averaging process, a differentiating process, an integrating process, and the like are possible.
In one embodiment, the probe movement data may be acceleration data and the target movement data may include velocity data and/or displacement data. In this case, the acceleration data may be subjected to an integration process to obtain velocity data and/or displacement data. Specifically, the acceleration data is integrated once, so that velocity data can be obtained, and the acceleration data is integrated twice, so that displacement data can be obtained. After the target motion data is obtained, the target motion data can be sent to the ultrasonic equipment, and the ultrasonic equipment can directly utilize the target motion data to execute corresponding services. Specifically, a probe movement data channel is provided between the ultrasonic device and the ultrasonic probe, for example, an SPI (Serial Peripheral Interface ) channel in fig. 1 is used for transmitting target movement data and/or probe movement data.
Referring to fig. 2 and fig. 4, fig. 4 is a flowchart of an ultrasonic probe switching method executed by an ultrasonic device according to an embodiment of the present application, including:
s202: and acquiring a switching request sent by the target ultrasonic probe.
S204: in response to the switching request, it is determined whether a switching condition is satisfied.
S206: and if the switching condition is met, switching the target ultrasonic probe to the currently used probe.
The three steps S202, S204, S206 are performed by the ultrasound apparatus. After the ultrasonic device obtains a switching request sent by a target ultrasonic probe (specifically, any one ultrasonic probe), it can be determined that the target ultrasonic probe is to be switched to a currently used probe. The present embodiment does not limit the specific determination manner in which the switching request is transmitted by the target ultrasound probe. For example, in one embodiment, each ultrasonic probe is connected to the ultrasonic device by using a separate cable, for example, refer to fig. 5, fig. 5 is a schematic diagram of a connection manner between an ultrasonic probe and an ultrasonic host, where the ultrasonic host is connected to probes a, … … and probes E through cables. Wherein each ultrasonic probe is connected with a probe switching unit by using an independent cable, and the probe switching unit belongs to ultrasonic equipment. The ultrasonic equipment can determine the corresponding ultrasonic probe according to the acquired cable interface identifier of the switching request. In another embodiment, the switching request generated by the ultrasonic probe can include the corresponding probe unique identification information. The probe unique identification information refers to information capable of uniquely identifying an ultrasonic probe, and a specific form is not limited, and may be a serial number, a probe model, and the like.
The switching condition refers to a condition allowing the probe to be switched, and the specific content thereof is not limited, and for example, the switching condition may be a working state condition, a motion state condition of the ultrasonic probe transmitting a switching request, a switching interval condition, or the like, and may be set according to actual needs.
In one embodiment, the switching condition is a working condition, and the user generally does not change the ultrasonic probe in the scanning process when using a certain ultrasonic probe to scan a patient, so that whether the user is currently in the ultrasonic scanning mode can be judged, if the user is in the ultrasonic scanning mode, it is indicated that the user is using a certain ultrasonic probe to scan the patient, and the ultrasonic probe is unlikely to be changed, so that a preset operation can be performed, for example, no operation is performed, and the switching request is ignored. If the ultrasonic scanning mode is not adopted, the fact that the target ultrasonic probe required by the ultrasonic scanning to be started is different from the ultrasonic probe used last time in the interval of two ultrasonic scanning by the user is indicated, and probe switching is required, so that the condition of the working state is met.
Further, in one embodiment, when it is determined that the ultrasonic scanning mode is currently in the ultrasonic scanning mode, a scanning position targeted by the ultrasonic scanning mode may be determined, and when the scanning position is matched with the target ultrasonic probe, that is, when the target ultrasonic probe can perform ultrasonic scanning on the scanning position, it is determined that the working state condition is satisfied. The above embodiment, based on the ultrasonic scanning mode, determines whether to respond to the switching of the target ultrasonic probe, and can effectively prevent false triggering. Further, when the history use probe does not meet the requirements, the target ultrasonic probe can be switched to the current use probe. The most proper ultrasonic probe can be used under the condition of preventing false triggering, and the accuracy of an ultrasonic scanning result is ensured.
In addition, if the same scanning position can be scanned by adopting a plurality of different ultrasonic probes, namely when the scanning position and the ultrasonic probes are in a one-to-many relationship, the priorities of the ultrasonic probes can be set, and each ultrasonic probe corresponds to a different priority. It can be understood that even though the plurality of ultrasonic probes can scan the scanned region, the application degree of each ultrasonic probe to scan the scanned region is different, and there may be a case that a certain ultrasonic probe is not very suitable in practice although it can scan the scanned region. The probe priority in this embodiment is used to indicate the application degrees of the ultrasonic probe and the scanning location, and it can be understood that the same ultrasonic probe may correspond to a plurality of scanning locations, but the application degrees of the ultrasonic probe to different scanning locations may be different. When the ultrasonic equipment acquires a switching request sent by the target ultrasonic probe, whether the switching request is matched with the scanned part or not is firstly judged. If the target priority is matched, the target priority of the target ultrasonic probe corresponding to the scanning position and the current priority of the current use probe corresponding to the scanning position are obtained, if the target priority is larger than the current priority, the step of switching the target ultrasonic probe into the current use probe can be executed, and meanwhile, the current priority is updated, otherwise, the switching is considered to be caused by false touch, because a user is more likely to adopt a more applicable ultrasonic probe rather than a less applicable ultrasonic probe.
In another embodiment, the switching condition is a non-false touch condition, and the ultrasonic device may touch a certain ultrasonic probe by mistake during operation, so that the user sends a switching request, but the user does not actually use the ultrasonic probe, so that the user does not need to switch the ultrasonic probe to the currently used probe. In this case, the ultrasound apparatus may acquire motion data transmitted by the ultrasound probe and obtain motion amplitude data based on the motion data. Or the ultrasonic equipment can acquire target motion data obtained by preprocessing the motion data sent by the ultrasonic probe, and acquire motion amplitude data based on the target motion data. The motion amplitude data refers to data representing the motion amplitude of the ultrasonic probe in a three-dimensional space, and the motion amplitude can be displacement, speed and the like, and is not particularly limited. According to different acquired data, namely the motion data or the target motion data, the specific mode for obtaining the motion amplitude data can be different, for example, the motion data can be subjected to processes such as integration, average and the like, so as to obtain the motion amplitude data. For target motion data, one or more items of data may be extracted therefrom as motion amplitude data. The target interval is an interval indicating that the motion amplitude is larger or smaller and does not belong to false touch, whether the motion amplitude data is in the target interval is judged, and if the motion amplitude data is in the target interval, the condition that the false touch is not met is determined.
In alternative embodiments, the switching conditions may also include a duration condition. Further, when the motion amplitude data of the ultrasonic probe is determined to be in the target interval, the condition that the non-false touch condition is met is determined; and determining the duration of the motion amplitude data of the ultrasonic probe in the target interval, and judging that the switching condition is met when the duration is larger than a time threshold.
Further, since the user generally needs to take out an ultrasonic probe vertically from the probe holder when using it, the motion amplitude data may include a vertical displacement, in which case it may be judged whether or not the vertical displacement is greater than a preset displacement. If yes, determining that the motion amplitude data of the ultrasonic probe is in a target interval. The preset displacement may be a preset fixed value, and the specific size of the fixed value is not limited, and may be 10 cm, for example. The preset position can also be set based on the change of the ultrasonic scanning object, and at the moment, the preset displacement matched with the ultrasonic scanning object can be determined pertinently based on the shape of the ultrasonic scanning object. For example, the preset displacement may be a height difference between a center point of the ultrasonic probe holder and a specific position above the detection stage. The specific position above the detection table can be the uppermost position of the scanned parts such as the abdomen, the neck and the like of the human body when the ultrasonic scanning object is lying on the detection table, and the preset displacement corresponding to the ultrasonic scanning object with a large figure is larger than the preset displacement corresponding to the ultrasonic scanning object with a small figure. In such an embodiment, the ultrasound apparatus may acquire shape information of the ultrasound scanning object, determine a preset displacement based on the shape information, and further determine that the motion amplitude data of the ultrasound probe is in the target section based on the preset displacement. Wherein the body information may be determined based on height, weight, gender, etc.
In another embodiment, the motion amplitude data may be horizontal displacement data. In general, a probe holder for accommodating an ultrasonic probe is not provided directly above a scanning site, but is provided laterally, and thus a user moves the ultrasonic probe to the scanning site by horizontally moving his/her hand in a certain range after picking up the ultrasonic probe. If the user misholds the ultrasonic probe, the situation is usually found in the horizontal movement process of the hand, and the misheld ultrasonic probe is replaced by the probe frame. In this case, the horizontal displacement amplitude of the ultrasonic probe may be smaller than that in the normal case. Correspondingly, the lower limit value of the target section may be set as a horizontal distance between the probe holder and a preset scanning position, which refers to a standard placement position of the scanning part, for example, a center position of the detection table, or may be determined according to a specific type of the scanning part, for example, the preset scanning positions corresponding to the neck and the abdomen may be different.
After determining that the switching condition is satisfied, the target ultrasonic probe that sent the switching request may be switched to the currently used probe so as to perform the ultrasonic scanning service using the same. The ultrasonic probe achieves data acquisition by emitting ultrasonic data (i.e., ultrasonic waves) and retrieving reflected echo data, the probe is currently used specifically for transmitting ultrasonic data to a target object and receiving echo data of the target object for the transmitted ultrasonic data. The scanning operation can thus be performed using echo data provided by the target ultrasound probe, in such a way that the switching of the currently used probe is completed. Specifically, echo data received by the target ultrasonic probe can be obtained, and as different types of ultrasonic probes need different operation data to work, operation parameters corresponding to the target ultrasonic probe can be loaded, and ultrasonic scanning operation on a target object is performed by using the operation parameters and the echo data. The execution mode of the ultrasonic scanning service can be that echo data is subjected to imaging processing by using operation parameters, specifically, echo data is subjected to filtering, calculating and other processing based on the operation parameters to obtain imaging data, and image rendering is performed by using the imaging data to obtain an ultrasonic image. The above-mentioned switching process is a software-angle switching process, and in terms of hardware, the ultrasonic device may control the relay switch circuit in the probe switching unit to implement the switching between probes.
In one embodiment, the ultrasonic apparatus includes a probe switching unit including relay switching circuits corresponding to respective ultrasonic probes; the ultrasonic probe before switching is a history use probe; the switching the target ultrasonic probe to a currently used probe comprises the following steps: closing a relay switch circuit corresponding to the probe switching unit and the history use probe in the ultrasonic equipment; and opening a relay switch circuit corresponding to the probe switching unit and the currently used probe in the ultrasonic equipment.
By applying the ultrasonic probe switching method provided by the embodiment of the application, the probe processor is arranged in the ultrasonic probe and can be communicated with the motion detection component, a signal channel is arranged between the probe processor and the motion detection component, after the motion detection component detects the motion of the ultrasonic probe, a switching signal is sent to the probe processor through the signal channel, after the probe processor detects the switching signal, a switching request is sent to the ultrasonic equipment, after the switching request is obtained, the ultrasonic equipment detects whether a switching condition is met, if so, the ultrasonic probe is determined to be the currently used probe, and the switching of the ultrasonic probe is completed. According to the method, the ultrasonic probe can actively detect the motion of the ultrasonic probe and actively report the switching request, the ultrasonic equipment can judge whether to switch according to the detection result of the switching condition, and a user can activate the probe switching in a probe moving mode without manual operation, so that the ultrasonic probe switching efficiency is improved.
Referring to fig. 6, fig. 6 is a flowchart of a specific method for switching an ultrasonic probe according to an embodiment of the present application. The ultrasonic equipment is connected with a plurality of ultrasonic probes, and each ultrasonic probe is provided with an MCU and an IMU. After the ultrasonic equipment and the ultrasonic probe start to work, the MCU and the IMU in the ultrasonic probe are initialized. Thereafter, when a certain ultrasonic probe moves, the IMU in the ultrasonic probe also moves, and at the same time, the IMU in the ultrasonic probe detects that the motion state of the ultrasonic probe changes, so that interrupt information (i.e., an interrupt signal) is sent to the MCU. After obtaining the interrupt signal sent by the IMU, the MCU reports interrupt information (i.e. interrupt request) to the host (i.e. ultrasonic device). The ultrasound device (host) determines whether it is in ultrasound scanning mode. If the ultrasonic probe is not in the ultrasonic scanning mode, the ultrasonic equipment judges whether the current movement of the ultrasonic probe is false trigger or not, and specifically, the method can be used for acquiring probe movement data sent by an MCU in the ultrasonic probe, and comparing the probe movement data with a target interval after acquiring movement amplitude data based on the probe movement data. And if the trigger is not false, executing ultrasonic probe switching. Otherwise, no processing is executed, and the IMU in each ultrasonic probe continues to detect the motion state of the IMU.
