Description

Technical Field

[0001] This application relates to the field of ultrasonic probe technology, and in particular to a zeroing control method, system, and storage medium for ultrasonic probes. Background Technology

[0002] Currently, the probes used in ultrasonic 3D imaging are typically mechanical volumetric probes. During 3D scanning, the probe's transducer oscillates back and forth driven by an internal motor. In non-3D mode, the transducer needs to remain stationary at the zero-position. Zeroing control of the probe involves stopping the transducer at the zero-position. Due to the structural limitations of current mechanical volumetric probes, the sensor output signal is often high regardless of whether the transducer's rotation angle is to the left or right of the zero-position. Therefore, related technologies cannot directly determine the transducer's zeroing direction based on the sensor's signal state. Instead, they require repeatedly adjusting the transducer's rotation angle, combining this with changes in the sensor's signal state to determine the zeroing direction, and then controlling the transducer to zero based on this determined direction. Furthermore, due to system propagation and response delays, the transducer cannot accurately stop at the preset zero-position. Consequently, zeroing control in related technologies often takes a considerable amount of time and cannot accurately control the transducer to return to the preset zero-position.

[0003] There is currently no effective solution to the problems of low zeroing efficiency and low accuracy of transducers in related technologies. Summary of the Invention

[0004] This embodiment provides a zeroing control method, system, and storage medium for an ultrasonic probe to solve the problems of low zeroing efficiency and low accuracy of transducers in related technologies.

[0005] Firstly, this embodiment provides a method for zeroing control of an ultrasonic probe. The ultrasonic probe is equipped with a sensor and a shielding component. The shielding component rotates synchronously with the transducer of the ultrasonic probe, and the sensor is fixedly positioned at a preset zeroing position of the transducer. The method includes:

[0006] The initial signal state of the sensor is obtained; the initial signal state is either an on state or an off state; wherein, the on state is the signal state output by the sensor when it is not blocked by the blocking component; the off state is the signal state output by the sensor when it is blocked by the blocking component.

[0007] The transducer is controlled to rotate continuously in the first rotation direction until the current signal state of the sensor undergoes its first change; the first rotation direction is the rotation direction in which the position of the transducer is zeroed, determined based on the initial signal state of the sensor.

[0008] The transducer is controlled to rotate in a second rotation direction until the current signal state of the sensor undergoes a second transition; wherein the second rotation direction is opposite to the first rotation direction, and the angle by which the transducer rotates in the second rotation direction is less than the angle by which it rotates in the first rotation direction.

[0009] In some embodiments, when the initial signal state is on, the first rotation direction of the transducer is the direction that causes the signal state of the sensor to jump to the blocking state.

[0010] In some embodiments, the method further includes:

[0011] After the sensor's current signal state undergoes a second transition, the transducer is controlled to rotate in a third rotation direction until the sensor's current signal state undergoes a third transition; the third rotation direction is opposite to the second rotation direction.

[0012] In some embodiments, the method further includes:

[0013] When the initial signal state is either an on state or an off state, after the current signal state of the sensor undergoes a second transition, the transducer is controlled to rotate in a third rotation direction until the current signal state of the sensor undergoes a third transition; the third rotation direction is opposite to the second rotation direction.

[0014] When the initial signal state is either an on state or an off state, the transducer is controlled to stop rotating after the current signal state of the sensor undergoes a second transition.

[0015] In some embodiments, when the initial signal state is a blocked state, the first rotation direction of the transducer is the direction that causes the signal state of the sensor to jump to an on state.

[0016] In some embodiments, controlling the transducer to rotate in a second rotational direction until the current signal state of the sensor undergoes a second transition includes:

[0017] The transducer is controlled to rotate in a second rotation direction at a preset step angle until the current signal state of the sensor undergoes a second jump.

[0018] In some embodiments, controlling the transducer to rotate in a second rotation direction by a preset step angle until the current signal state of the sensor undergoes a second transition includes:

[0019] Each time the transducer is controlled to rotate once in the second rotation direction by a preset step angle, it is determined whether the current signal state of the sensor has changed for the second time. If so, the transducer is controlled to stop the step rotation; otherwise, the transducer is controlled to continue rotating once in the second rotation direction.

[0020] In some embodiments, controlling the transducer to rotate continuously in a first rotation direction until the current signal state of the sensor undergoes its first change includes:

[0021] Within the limit rotation angle of the transducer, the transducer is controlled to rotate continuously in the first rotation direction until the current signal state of the sensor undergoes its first change.

[0022] Secondly, this embodiment provides a zeroing control system for an ultrasonic probe, including: an ultrasonic probe and a controller; wherein, the ultrasonic probe is provided with a shield and a sensor, the shield rotates synchronously with the transducer of the ultrasonic probe, and the sensor is fixedly installed at a preset zeroing position of the transducer;

[0023] The ultrasonic probe is used to perform ultrasonic three-dimensional imaging of the object being tested.

[0024] The controller is used to execute the zeroing control method for the ultrasonic probe described in the first aspect above.

[0025] Thirdly, this embodiment provides a storage medium storing a computer program that, when executed by a processor, implements the zeroing control method for the ultrasonic probe described in the first aspect.

[0026] Compared with related technologies, this embodiment provides a zeroing control method, system, and storage medium for an ultrasonic probe. The zeroing control method first acquires the initial signal state of the sensor; the initial signal state is either an on state or an off state; the on state is the signal state output when the sensor is not off-target; the off state is the signal state output when the sensor is off-target. Next, the transducer is controlled to rotate continuously in a first rotation direction until the sensor's current signal state undergoes its first change; the first rotation direction is the rotation direction for zeroing the transducer position determined based on the sensor's initial signal state. Finally, the transducer is controlled to rotate in a second rotation direction until the sensor's current signal state undergoes its second change; the second rotation direction is opposite to the first rotation direction, and the angle of rotation of the transducer in the second rotation direction is less than the angle of rotation in the first rotation direction. It can determine the position of the transducer based on the signal status of the sensor, thereby achieving accurate control of the transducer rotation. Furthermore, by detecting two signal transitions, it can accurately position the transducer at a preset zero position, thereby improving the efficiency and accuracy of the transducer zero-point control.

[0038] The method embodiments provided in this example can be executed on a terminal, computer, or similar computing device. For example, it can run on a terminal.

[0041] This embodiment provides a zeroing control method for an ultrasonic probe. The ultrasonic probe is equipped with a sensor and a shielding component. The shielding component rotates synchronously with the transducer of the ultrasonic probe, and the sensor is fixedly installed at a preset zeroing position of the ultrasonic transducer. Figure 2 This is a flowchart of the zeroing control method for the ultrasonic probe in this embodiment, as follows: Figure 2 As shown, the process includes the following steps:

[0042] Step S210: Obtain the initial signal state of the sensor; the initial signal state is either an on state or an off state; wherein, the on state is the signal state output by the sensor when it is not blocked by the blocking component; the off state is the signal state output by the sensor when it is blocked by the blocking component.

[0043] The ultrasonic probe in this embodiment is a volumetric probe equipped with a sensor for probe zeroing. For example, it can be a mechanical volumetric probe driven by a motor, or it can be other types of volumetric probes. This embodiment does not specifically limit the type of probe. Figure 3 This is a schematic diagram of one structure of the ultrasonic probe in this embodiment. Figure 3As shown, the ultrasonic probe includes a transducer 301. In addition, the ultrasonic probe also includes a sensor 302 and a blocking member 303. The sensor 302 is fixedly mounted at a preset zero position of the transducer, for example, fixedly mounted on the base of the transducer. The blocking member 303 can be mounted on the rotating shaft of the transducer, and the blocking member 303 rotates synchronously with the transducer 301. Specifically, the sensor 302 can be a photoelectric switch, with the transmitter and receiver integrated. In this embodiment, when the transducer 301 is not in the preset zero position, the signal state output by the sensor 302 is either an on state or a blocked state, where one signal state corresponds to a high level and the other to a low level. For example, when the sensor 302 is blocked by the blocking member 303, the output signal state is blocked, and the output signal is low; when the sensor 302 is not blocked by the blocking member 303, the output signal state is on, and the output signal is high.

[0044] Figure 4 This is a schematic diagram illustrating the positional relationship between the sensor and the blocking element in this embodiment. Figure 4 As shown on the left, the blocking member 303 blocks the sensor 302 as the transducer rotates synchronously; as Figure 4 As shown in the middle section, the positional relationship between the blocking component 303 and the sensor 302 is at the critical state of blocking and not blocking. At this time, the transducer is in the zero position, and the signal output by the sensor 302 may be in an on state or a blocked state depending on the error. Figure 4 As shown on the right, the shielding component 303 does not block the sensor 302 at this time.

[0045] When the transducer is not in the zero position, its rotation angle relative to the zero position belongs to one of two deflection ranges, which are located on both sides of the zero position. Figure 5 This is a schematic diagram illustrating the correspondence between sensor signal states and transducer rotation angles in this embodiment. For example... Figure 5 As shown, when the current rotation angle of the transducer is within the first deflection range relative to the preset zero position, such as -90 degrees to 0 degrees, the sensor is blocked by the blocking component. At this time, the initial signal state of the sensor is the blocked state, and it can output a low level. When the current angle of the transducer is within the second deflection range relative to the preset zero position, such as 0 degrees to 90 degrees, the sensor is not blocked by the blocking component. At this time, the initial signal state of the sensor is the on state, and it can output a high level. The above-mentioned first deflection range and second deflection range constitute the maximum structural limit angle range of the transducer's rotation. The correspondence between the blocked state and the on state and the high and low levels is only an example, and this embodiment does not specifically limit the correspondence between the blocked state and the on state and the high and low levels.

[0046] Furthermore, since the shielding member rotates synchronously with the transducer in this embodiment, when the transducer is zeroed, the signal status of the sensor can be detected to determine whether the rotation angle of the transducer is within the first deflection range or the second deflection range, thereby determining the zeroing direction of the transducer.

[0047] Step S220: Control the transducer to rotate continuously in the first rotation direction until the current signal state of the sensor changes for the first time; the first rotation direction is the rotation direction in which the transducer position is zeroed, determined according to the initial signal state of the sensor.

[0048] The ultrasonic transducer can be rotated by a motor inside the ultrasonic probe. Specifically, during the rotation, the sensor's signal state will change abruptly when the transducer passes through the zero-point position. For example, a high-to-low level transition will occur. Therefore, the transducer needs to be continuously rotated in a defined first direction until the sensor's signal state undergoes its first change. For example, if the transducer is in a deflection range of -90° to 0°, and the initial signal state of the sensor is in an obstructed state, then the first rotation direction is the direction that causes the sensor's signal state to change to an on state. If rotating the transducer clockwise relative to a fixed base at a fixed viewing angle can cause the sensor's signal state to change from an obstructed state to an on state, then the first rotation direction is clockwise at that fixed viewing angle; conversely, if it is necessary to change the sensor's signal state from an on state to an obstructed state, then the first rotation direction is counterclockwise at that fixed viewing angle. It should be noted that the above counterclockwise and clockwise directions are merely illustrative examples for ease of description and do not constitute a specific limitation on the zero-point control method of this embodiment. This embodiment uses the signal status of the sensor to determine the rotation direction of the transducer when it returns to zero, thereby avoiding vibration and abnormal noise caused by the transducer rotating to the structural limit in the opposite direction to the zeroing direction.

[0049] Step S230: Control the transducer to rotate in the second rotation direction until the current signal state of the sensor changes for the second time; wherein, the second rotation direction is opposite to the first rotation direction, and the angle of the transducer rotating in the second rotation direction is less than the angle of the transducer rotating in the first rotation direction.

[0050] When the sensor output signal state undergoes its first change, after the transducer stops moving, this embodiment considers that the transducer may remain in motion due to signal transmission delays and system response delays, and thus cannot stop precisely at the zero position. Therefore, after the transducer undergoes its first change and stops moving, this embodiment immediately controls the transducer to rotate a small distance in a second rotation direction opposite to the first rotation direction until the sensor signal state changes again, i.e., the second change. This ensures that the transducer stops more accurately at the zero position.

[0051] This embodiment, based on the corresponding setup of the sensor and the shielding component, determines the rotation direction of the transducer by detecting the signal state output by the sensor, and then achieves zero-reset control of the transducer in the ultrasonic probe through two signal jump detections. Compared with related technologies, it can improve the efficiency and accuracy of zero-reset control.

[0052] Steps S210 to S230 above involve acquiring the initial signal state of the sensor; the initial signal state is either an on state or an off state; wherein, the on state is the signal state output by the sensor when it is not blocked by the blocking component; the off state is formed when the sensor is blocked by the blocking component; controlling the transducer to continuously rotate in a first rotation direction until the current signal state of the sensor undergoes its first change; the first rotation direction is the rotation direction for zeroing the transducer position determined based on the initial signal state of the sensor; controlling the transducer to rotate in a second rotation direction until the current signal state of the sensor undergoes its second change; wherein, the second rotation direction is opposite to the first rotation direction, and the angle of rotation of the transducer in the second rotation direction is less than the angle of rotation in the first rotation direction. This allows for the determination of the transducer's position based on the sensor's signal state, thereby achieving accurate control of the transducer's rotation, and by detecting two signal changes, the transducer is accurately positioned at a preset zeroing position, thus improving the efficiency and accuracy of the transducer's zeroing control.

[0053] In one embodiment, when the initial signal state is on, the first rotation direction of the transducer is the direction that causes the sensor's signal state to jump to the blocked state.

[0054] Specifically, when the initial signal state is on, the rotation direction that causes the signal state to change to an occlusion state can be determined based on a pre-determined correspondence between the transducer's rotation direction and the sensor's signal state. For example, at a fixed viewing angle, when the occlusion element does not obstruct the sensor, the transducer needs to rotate counterclockwise to make the occlusion element obstruct the sensor, thus bringing the transducer to zero. In this case, the first rotation direction is the aforementioned counterclockwise direction. Therefore, this embodiment can accurately determine the transducer's rotation direction.

[0055] Furthermore, in one embodiment, the above-described ultrasonic probe zeroing control method may further include:

[0056] After the sensor's current signal state changes for the second time, the transducer is controlled to rotate in the third rotation direction until the sensor's current signal state changes for the third time; the third rotation direction is opposite to the second rotation direction.

[0057] Therefore, in this embodiment, after the sensor's current signal state undergoes a second transition, the transducer is controlled to rotate in a third direction so that the sensor's current signal state undergoes a third transition, thereby more accurately stopping the transducer at the preset zero position.

[0058] Furthermore, in one embodiment, the above-mentioned zeroing control method for the ultrasonic probe may also include:

[0059] When the initial signal state is either on or off, after the sensor's current signal state changes for the second time, the transducer is controlled to rotate in the third rotation direction until the sensor's current signal state changes for the third time; the third rotation direction is opposite to the second rotation direction; when the initial signal state is either on or off, after the sensor's current signal state changes for the second time, the transducer is controlled to stop rotating.

[0060] For example, when the initial signal state is "on," if the transducer is rotated in the first rotation direction to cause the sensor's signal state to change from "on" to "blocked," to avoid the transducer being affected by signal transmission delay, system response delay, etc., the transducer is then rotated again in the second rotation direction to cause the sensor's signal state to change to "on" again. To ensure that the transducer remains stationary on the same side of the zero position after returning to zero from any direction, the transducer can be slightly rotated again after the second signal state change, causing a third signal state change. In this case, if the initial signal state of the sensor is "blocked," a third signal state change is unnecessary. In this case, regardless of whether the initial signal state is "on" or "blocked," the transducer can remain stationary on the same side of the zero position. The angle of rotation of the transducer in the third rotation direction can be less than or equal to the angle of rotation in the second rotation direction.

[0061] Understandably, if the sensor's initial signal state is blocked, the transducer can be controlled to rotate to cause the sensor to undergo a third transition. Conversely, if the sensor's initial signal state is on, only the transducer needs to be controlled to rotate to cause the sensor to undergo two transitions. Based on this, this embodiment ensures that the transducer stops on the same side after returning to zero at any position, thereby improving the consistency of the zeroing position.

[0062] In another embodiment, when the initial signal state is a blocked state, the first rotation direction of the transducer is the direction that causes the sensor's signal state to jump to an on state.

[0063] When the initial signal state is obstructed, the rotation direction to change the signal state to on can be determined based on a pre-defined correspondence between the transducer's rotation direction and the sensor's signal state. For example, at a fixed viewing angle, when the obstructing element blocks the sensor, the transducer needs to rotate clockwise to prevent the obstructing element from blocking the sensor, thus bringing the transducer to zero. In this case, the first rotation direction is the aforementioned clockwise direction. Therefore, this embodiment can accurately determine the transducer's rotation direction.

[0064] Furthermore, in one embodiment, based on the above step S230, controlling the transducer to rotate in the second rotation direction until the current signal state of the sensor undergoes a second transition, specifically may include:

[0065] The transducer is controlled to rotate in a second rotation direction at a preset step angle until the current signal state of the sensor changes for the second time.

[0066] Specifically, when the sensor's current signal undergoes its first change, the transducer is controlled to stop moving. Then, it rotates in small increments in a second direction opposite to the first rotation direction until the sensor's current signal state undergoes a second change. For example, the transducer can be controlled to rotate in steps with fewer than 100 pulses. Exemplarily, each step angle can be less than 0.01 degrees, such as 0.001 degrees, 0.0013 degrees, 0.0015 degrees, 0.0017 degrees, or 0.002 degrees. Other pulse counts can also be set; this embodiment does not specifically limit this. By using a step-by-step rotation method, small adjustments to the transducer's rotation direction can be achieved, thus avoiding excessively large adjustments that could cause the transducer to deviate from its zero-position. Based on this, this embodiment can improve the accuracy of the transducer's zeroing.

[0067] In one embodiment, controlling the transducer to rotate in a second rotation direction by a preset step angle until the current signal state of the sensor undergoes a second transition may include:

[0068] Each time the transducer is controlled to rotate once in the second rotation direction by a preset step angle, it is determined whether the current signal state of the sensor has changed for the second time. If so, the transducer is controlled to stop the step rotation; otherwise, the transducer is controlled to continue rotating once in the second rotation direction.

[0069] To further improve the accuracy of transducer zero-reset control during stepping rotation, the sensor signal state can be checked after each rotation to determine if a second transition has occurred. Once a transition is detected, the current stepping rotation is controlled. By cyclically repeating this stepping rotation and sensor signal state checks, the accuracy of zero-reset control is improved.

[0070] Specifically, in one embodiment, based on the above step S220, controlling the transducer to continuously rotate in the first rotation direction until the current signal state of the sensor undergoes its first change may include:

[0071] Within the transducer's limit rotation angle, the transducer is controlled to rotate continuously in the first rotation direction until the sensor's current signal state undergoes its first jump.

[0072] In other words, the transducer's limit rotation angle can be set as the maximum angle limit for continuous control of the transducer's rotation. The transducer will then rotate continuously without exceeding this maximum angle limit until the sensor's current signal state undergoes its first change. This limit rotation angle is the angle at which the transducer rotates from one structural limit to the other. Therefore, this embodiment avoids vibration and abnormal noise caused by the transducer rotating to its structural limit and reduces wear on the transducer's various mechanical components.

[0073] The present embodiment will now be described and illustrated through preferred embodiments.

[0074] Figure 6 This is a flowchart of the zeroing control method for the ultrasonic probe according to a preferred embodiment. Figure 6 As shown, the zeroing control method for this ultrasonic probe includes the following steps:

[0075] Step S601: Obtain the initial signal state of the sensor; wherein, the ultrasonic probe is equipped with a sensor and a shielding component, the shielding component rotates synchronously with the transducer of the ultrasonic probe, and the sensor is fixedly set at the preset zero position of the transducer.

[0076] Step S602: Determine whether the initial signal state of the sensor is an occlusion state; if yes, proceed to step S603; otherwise, proceed to step S604.

[0077] Step S603: Control the transducer to rotate in the positive angle direction; execute step S605; wherein, the positive angle direction can be the rotation direction that enables the sensor output signal to be in the on state; specifically, when controlling the transducer to rotate, the angle range of the transducer rotating in the positive angle direction can be preset based on the mechanical structure of the ultrasonic probe, the maximum structural limit of the transducer rotation, etc.

[0078] Step S604: Control the transducer to rotate in a negative angle direction; execute step S610; wherein the negative angle direction can be the rotation direction in which the signal output of the sensor is blocked; similarly, when controlling the transducer to rotate in a negative angle direction, the angle range of the transducer to rotate in a negative angle direction can be preset based on the mechanical structure of the ultrasonic probe, the maximum structural limit of the transducer rotation, etc.

[0079] Step S605: Determine whether the current signal state of the sensor has changed; if yes, proceed to step S606; otherwise, continue to step S603.

[0080] Step S606: Control the transducer to stop moving;

[0081] Step S607: Control the transducer to rotate in a negative angle direction; for example, the number of step pulses can be less than 100, and the step angle can be less than 0.01 degrees, such as 0.001 degrees, 0.0013 degrees, 0.0015 degrees, 0.0017 degrees or 0.002 degrees, etc., to control the transducer to rotate in a step.

[0082] Step S608: Determine whether the current signal of the sensor has changed; if yes, proceed to step S609; otherwise, continue to step S607.

[0083] Step S609: Control the transducer to stop rotating and end the zeroing control process;

[0084] Step S610: Determine whether the current signal of the sensor has changed; if yes, proceed to step S611; otherwise, continue to step S604.

[0085] Step S611: Control the transducer to stop moving;

[0086] Step S612: Control the transducer to rotate in a positive angle direction;

[0087] Step S613: Determine whether the current signal of the sensor has changed; if yes, proceed to step S607; otherwise, continue to step S612.

[0088] Steps S601 to S613 described above can determine the position of the transducer based on the signal state of the sensor, thereby achieving accurate control of the transducer rotation. Furthermore, by detecting two signal transitions, the transducer is accurately positioned at the preset zero position, thus improving the efficiency and accuracy of the transducer zero-reset control.
