Abstract
Description
Technical Field
[0001] This disclosure relates to an ultrasonic probe including a transducer capable of moving between a neutral position and an offset position based on the detection of a non-use trigger or a use trigger. Furthermore, this disclosure relates to a system and method for detecting use triggers or non-use triggers and controlling the transducer of the ultrasonic probe between the neutral and offset positions. Background Technology
[0002] An ultrasound system typically includes a control console that houses the various components of the ultrasound system and supports a display for showing ultrasound images. The ultrasound system may include one or more ultrasound probes, each configured to connect to the control console and acquire ultrasound data of various anatomical regions of interest to the subject. For example, an ultrasound system may include linear probes, phased array probes, intracavitary probes, convex probes, etc.
[0003] An ultrasound probe may include a transducer configured to generate ultrasound signals, transmit ultrasound signals toward a subject's region of interest, receive echo ultrasound signals backscattered from the subject's region of interest, and generate ultrasound data based on the echo ultrasound signals. The ultrasound system may generate ultrasound images based on the echo ultrasound signals. The transducer may include various components such as lenses, acoustic matching layers, piezoelectric layers, acoustic dematching layers, etc.
[0004] To perform ultrasound imaging, the operator can manipulate the ultrasound probe around the anatomical region of interest on the subject to obtain ultrasound data of the region of interest. After ultrasound imaging, the operator can store the ultrasound probe in the probe holder of the console. Alternatively, the operator can disconnect the ultrasound probe from the console, move the ultrasound probe to the storage area, connect the ultrasound probe to another console, or perform a sterilization process, etc. In some cases, the operator may move the console to another location.
[0005] During any of the foregoing circumstances, the ultrasound probe may be susceptible to external impact. For example, an operator may unintentionally drop the ultrasound probe while moving it from the console to the subject, moving it around the subject, moving it from the subject to the console, or moving it from the console to another area. Alternatively, the ultrasound probe may fall from its holder due to external force or movement of the console. Alternatively, the ultrasound probe may unintentionally come into contact with an external object. Specifically, the size, construction, and materials of the transducer components may make the transducer susceptible to damage from external impact. Therefore, after exposure to an external impact resulting from transducer damage, the ultrasound probe may become inoperable for ultrasound imaging. Summary of the Invention
[0006] This invention provides a more detailed description of concepts in specific embodiments. It should not be used to identify essential features of the claimed subject matter, nor should it be used to limit the scope of the claimed subject matter.
[0007] According to one aspect, an ultrasound system may include: an ultrasound probe including a transducer configured to acquire ultrasound data of a region of interest of a subject; and one or more processors configured to: detect a non-use trigger indicating that the ultrasound probe was not used to acquire ultrasound data of the region of interest of the subject; and control the transducer of the ultrasound probe to move from a neutral position to an offset position based on the detection of the non-use trigger.

[0019] Figure 9 This is a flowchart of an example method for controlling the movement of an ultrasound probe transducer between an offset position and a neutral position based on a detected trigger. Detailed Implementation
[0020] As explained above, ultrasonic probes can be easily damaged by external impacts. Specifically, considering the location of the transducer in the ultrasonic probe and the tendency of the ultrasonic probe to come into contact with external objects or surfaces at the transducer location, the transducer of the ultrasonic probe may be particularly vulnerable.
[0021] Some embodiments described herein provide an ultrasonic probe including a transducer capable of moving between a neutral position and an offset position based on the detection of a non-use trigger or an use trigger. Specifically, the transducer can be controlled to move to the offset position based on the detection of a non-use trigger. The transducer can remain in the offset position until it is controlled to move to the neutral position based on the detection of a use trigger. In the offset position, the transducer may be less susceptible to damage from external impacts compared to when it is in the neutral position. In this way, the ultrasonic probe of this disclosure is more robust than ultrasonic probes that include a fixed transducer. Therefore, this disclosure provides an improved ultrasonic probe and a technical improvement in the field of ultrasonic imaging technology.
[0022] Furthermore, this disclosure reduces or eliminates the need for stringent handling procedures for ultrasound probes, which improves the efficiency of non-scanning processes such as cleaning, sterilization, and / or disposal. Additionally, this disclosure allows ultrasound probes to have small form factors and / or reduces the need for various protective features, increased component sizes, or sensors included in the ultrasound probe. For example, in some cases, the ultrasound probe may not require relatively thick external protective features to protect the lens. Such external protective features may increase the gap between the transducer lens and the subject, which can negatively impact image quality, increase signal attenuation, and increase reverberation. Therefore, the ultrasound probe of this disclosure acquires ultrasound data with improved image quality compared to ultrasound probes with external protective features. Furthermore, the ultrasound probe of this disclosure can utilize lenses with relatively small form factors, which improves image quality compared to ultrasound probes implementing thicker lenses. Additionally, the ultrasound probe may not require sensors to detect drop events. Such sensors may have high false positive rates and / or may increase the complexity of the ultrasound probe. By eliminating the need for sensors, the ultrasonic probe of this disclosure reduces various situations caused by false positives and / or may be relatively less complex compared to ultrasonic probes that include such sensors. Furthermore, the ultrasonic probe of this disclosure can maintain the transducer in an offset position until a use trigger is detected. In this way, the ultrasonic probe provides a protection mechanism for additional external impact events besides drop events. Moreover, the ultrasonic probe can maintain the transducer in an offset position after the ultrasonic probe is disconnected from the control panel and / or after the control panel is powered off. In this way, the ultrasonic probe can increase the duration of protection maintained for the transducer.

[0034] Figure 2 This is a diagram of an example ultrasound system 100 according to the implementation plan. For example... Figure 2 As shown, the ultrasound system 100 may include a console 106, a display 120, and a probe holder 126. The probe holder 126 may be disposed on top of the display 120 and may include a plurality of slots, each configured to hold and support an ultrasound probe 102.
[0035] Figure 3 This is a diagram of an example ultrasonic probe 102 according to the implementation scheme. For example... Figure 3 As shown, the ultrasound probe 102 may include a housing 302, a support 304, a rotating frame 306, and a transducer 104. The housing 302 may be configured to house various components of the ultrasound probe 102. The support 304 may be configured to support the rotating frame 306 and allow the rotating frame to rotate about one or more axes. For example, the rotating frame 306 may rotate about such... Figure 3 The z-axis shown is as follows: Figure 3 The x-axis shown and / or as shown Figure 3 Rotation along the y-axis as shown. The rotating frame 306 can be configured to rotate around, as shown... Figure 3 One or more axes are shown that rotate and can be configured to support transducer 104.
[0036] Figure 4 This is a diagram of an example ultrasonic probe 102 according to the implementation scheme. For example... Figure 4As shown, the ultrasound probe 102 may include a support 304, a rotating frame 306, a transducer 104, a rotating device 402, and a guide wire 404. The rotating device 402 may be connected to the rotating frame 306 via the guide wire 404. Based on the movement of the rotating device 402, the rotating frame 306 may rotate around... Figure 4 Rotation of one or more axes as shown.
[0037] Figure 5 This is a diagram of an example transducer 104 of an ultrasonic probe according to the implementation scheme. (See diagram for example.) Figure 5 As shown, transducer 104 may include a lens 502, an acoustic matching layer 504, a first electrode 506, a piezoelectric layer 508, a second electrode 510, and an acoustic dematching layer 512. Lens 502 may be configured to direct and focus an ultrasound signal toward a region of interest of the subject. For example, lens 502 may be a polymer. Acoustic matching layer 504 may be configured to facilitate impedance matching, which may exist between a relatively high-impedance transducer 104 and a relatively low-impedance subject. For example, acoustic matching layer 504 may be graphite, metal, etc. First electrode 506 may be a signal electrode, and second electrode 510 may be a ground electrode; both electrodes are configured to contact piezoelectric layer 508 to transmit an electrical signal. Alternatively, first electrode 506 may be a ground electrode, and second electrode 510 may be a signal electrode; both electrodes are configured to contact piezoelectric layer 508. For example, first electrode 506 and / or second electrode 510 may be gold, copper, nickel, silver, chromium, aluminum, etc. The piezoelectric layer 508 can be configured to receive an electrical signal, deform based on the electrical signal, generate an ultrasonic signal based on the deformation, and transmit the ultrasonic signal to the region of interest. Additionally or alternatively, the piezoelectric layer 508 can be configured to receive an echo signal reflected from the region of interest, deform based on the echo signal, generate an electrical signal based on the deformation, and transmit the electrical signal. For example, the piezoelectric layer 508 may be Pb(Mg) 1 / 3 Nb 2 / 3 )O3-PbTiO3(“PMN-PT”), Pb(In 1 / 2 Nb 1 / 2 O3-Pb(Mg) 1 / 3 Nb 2 / 3 Pb(ZrTi)O3 (“PIN-PMN-PT”) or Pb(ZrTi) (“PZT”) are examples of materials that can be used. The piezoelectric layer 508 may include electrically insulating regions forming the various elements of the ultrasonic probe 102. The acoustic dematching layer 512 may be configured to reduce insertion loss and enhance the frequency bandwidth of the transducer 104. For example, the acoustic dematching layer 512 may be tungsten carbide, silicon carbide, etc. Although... Figure 5 Specific components are shown, but it should be understood that transducer 104 may include components that are compatible with... Figure 5The components shown are compared to additional components, fewer components, or components arranged differently. Additionally, the transducer 104 may employ mechanisms other than bulk piezoelectric mechanisms for electromechanical conversion. For example, the transducer 104 may be configured as a capacitive micromechanical ultrasonic transducer (cMUT) or a piezoelectric micromechanical ultrasonic transducer (pMUT), etc.
[0038] Figure 6 This is a diagram of an example ultrasonic probe 102 according to the implementation scheme. For example... Figure 6 As shown, the ultrasound probe 102 may include a controller 602, a mobile device 604, and a transducer 104. The controller 602 may be configured to receive signals from a processor 118 and control the mobile device 604 to move the transducer 104 between a neutral position and an offset position. For example, the controller 602 may be configured to receive signals from the processor 118 based on the processor 118 detecting a non-use trigger and control the mobile device 604 to move the transducer 104 from the neutral position to the offset position. As another example, the controller 602 may be configured to receive signals from the processor 118 based on the processor 118 detecting a use trigger and control the mobile device 604 to move the transducer 104 from the offset position to the neutral position. The controller 602 may be a CPU, GPU, APU, microprocessor, microcontroller, DSP, FPGA, ASIC, or another type of processing component. The mobile device 604 may be configured to move the transducer between the neutral position and the offset position. For example, the mobile device 604 may be a rotating device, a motor, actuator, spring, lever, etc.
[0039] Figure 7A This is a diagram of an example transducer 104 of an ultrasonic probe 102 in a neutral position according to the implementation scheme. (See diagram for example.) Figure 7A As shown, axis 702 can correspond to the longitudinal axis of the ultrasonic probe 102, the longitudinal axis of the support 304, or the longitudinal axis of the housing 302 of the ultrasonic probe 102, etc. Furthermore, as... Figure 7A As shown, axis 704 may correspond to the longitudinal axis of transducer 104. The neutral position may be defined as a position where axis 702 and axis 704 are substantially parallel. As used herein, "substantially parallel" may mean that axis 702 and axis 704 are offset by 0°, 2°, or 5°, etc.
[0040] Figure 7B This is a diagram of an example transducer 104 of an ultrasonic probe 102 in an offset position according to the implementation scheme. (See diagram for example.) Figure 7B As shown, axis 702 can correspond to the longitudinal axis of the ultrasonic probe 102, the longitudinal axis of the support 304, or the longitudinal axis of the housing 302 of the ultrasonic probe 102, etc. Furthermore, as... Figure 7BAs shown, axis 704 may correspond to the longitudinal axis of transducer 104. The offset position can be defined as a position where axis 702 is substantially offset from axis 704. As used herein, "substantially offset" may mean an offset of 20°, 25°, 30°, 40°, 45°, 60°, 70°, 90°, or 100° between axis 702 and axis 704. In other words, as shown, axis 702 and axis 704 may be offset by an angle 706. Angle 706 may be 20°, 25°, 30°, 40°, 45°, 60°, 70°, 90°, 100°, etc. In this way, the rotating frame 306 can protect transducer 104 from external impacts to the ultrasonic probe 102 because the rotating frame 306 is in the position where transducer 104 would otherwise be if it were still in a neutral position.
[0041] Although Figure 7 depicts axis 704 as substantially parallel to the longitudinal axis of the ultrasound probe 102 in the neutral position, it should be understood that axis 704 can be any predetermined axis relative to the ultrasound probe 102 in the neutral position. In any case, the offset position can be a position offset from the neutral position, regardless of the actual location of the neutral position.
[0042] Figure 8 This is a flowchart of an example method 800 for controlling the movement of the transducer 104 of an ultrasound probe 102 between a neutral position and an offset position based on the detection of a non-use trigger. Operation of method 800 may be performed by one or more components of a console 106. However, in other embodiments, one or more operations of method 800 may be performed by one or more components of the ultrasound probe 102.
[0043] like Figure 8 As shown, method 800 may include detecting a non-use trigger (operation 802) indicating that an ultrasound probe is not in use. For example, processor 118 may detect a non-use trigger indicating that an ultrasound probe 102 is not in use. A non-use trigger may be a trigger indicating that an ultrasound probe 102 is not in use. As used herein, "unused" may mean that the ultrasound probe 102 is not currently used for ultrasound imaging, is not intended to be used for ultrasound imaging, etc.
[0044] According to the implementation scheme, a non-use trigger can be a user input via user input device 116 that deselects ultrasound probe 102 for ultrasound imaging via ultrasound system 100. For example, an operator can interact with user input device 116 to input user input that deselects ultrasound probe 102 for ultrasound imaging. Processor 118 can detect a non-use trigger based on the user input.
[0045] Alternatively, a non-use trigger could be user input via user input device 116 to select another ultrasound probe 102 for ultrasound imaging via ultrasound system 100. For example, an operator could interact with user input device 116 to input user input that selects another ultrasound probe 102 for ultrasound imaging. Processor 118 can detect non-use triggers based on user input.
[0046] Alternatively, a non-use trigger can be the positioning of the ultrasound probe 102 within the probe holder 126 of the ultrasound system 100. For example, an operator may position the ultrasound probe 102 within the probe holder 126 of the ultrasound system 100 after performing ultrasound imaging. The processor 118 may detect a non-use trigger based on the positioning of the ultrasound probe 102 within the probe holder 126. For example, the processor 118 may detect a non-use trigger based on signals received from sensors of the ultrasound system 100, tracking data received from an external tracking system, or signals received from the ultrasound probe 102, which indicate that the ultrasound probe 102 is positioned within the probe holder 126.
[0047] Alternatively, a non-use trigger may be the absence of contact between the subject and the ultrasound probe 102. For example, an operator may remove the ultrasound probe 102 from contact with the subject after ultrasound imaging has been performed. The processor 118 may detect a non-use trigger based on the absence of contact between the subject and the ultrasound probe 102. For example, the processor 118 may detect a non-use trigger based on signals received from sensors of the ultrasound system 100, tracking data received from an external tracking system, or signals received from the ultrasound probe 102, which indicate that the ultrasound probe 102 is not in contact with the subject.
[0048] Alternatively, a non-use trigger can be the absence of contact between the operator and the ultrasound probe 102. For example, the operator may release the ultrasound probe 102 after ultrasound imaging. The processor 118 can detect a non-use trigger based on the absence of contact between the operator and the ultrasound probe. For example, the processor 118 can detect a non-use trigger based on signals received from sensors of the ultrasound system 100, tracking data received from an external tracking system, or signals received from the ultrasound probe 102, indicating that the ultrasound probe 102 is not in contact with the operator.
[0049] Alternatively, a non-use trigger may be the absence of an ultrasound image displayed via display 120. For example, if ultrasound probe 102 is not near the subject, display 120 may not display any ultrasound image. Processor 118 may detect a non-use trigger based on the absence of an ultrasound image displayed via display 120.
[0050] Alternatively, a non-use trigger may be the absence of an echo signal received via ultrasound probe 102. For example, ultrasound probe 102 may not receive any echo signal after it is no longer near the subject. Processor 118 may detect a non-use trigger based on the absence of an echo signal received via ultrasound probe 102.
[0051] Alternatively, the non-use trigger may be the generation of an ultrasound image that includes a quality metric that meets a threshold. For example, ultrasound probe 102 may generate an ultrasound image that includes a quality metric (e.g., noise, sharpness, contrast, or resolution) that meets a threshold indicating low quality when ultrasound probe 102 is not near the subject. Processor 118 may detect the non-use trigger based on the generated ultrasound image that includes a quality metric that meets the threshold.
[0052] Alternatively, a non-use trigger could be the position of the ultrasound probe 102 relative to the ultrasound system 100. For example, after ultrasound imaging, the operator can position the ultrasound probe 102 in a position indicating that the ultrasound probe 102 was not used for ultrasound imaging. The processor 118 can detect a non-use trigger based on the position of the ultrasound probe 102 relative to the ultrasound system 100. For example, the processor 118 can detect a non-use trigger based on signals received from sensors of the ultrasound system 100, tracking data received from an external tracking system, or signals received from the ultrasound probe 102, which identify the position of the ultrasound probe 102 relative to the ultrasound system 100.
[0053] Alternatively, the non-use trigger can be a time frame. For example, a time frame can be the elapsed time since the start of ultrasound imaging, the elapsed time since the end of ultrasound imaging, the time of day, a day of week, etc. The processor 118 can detect the non-use trigger based on the time frame.
[0054] Alternatively, a non-use trigger can be a user input via user input device 116 that powers off the ultrasound system 100. For example, an operator can interact with user input device 116 to power off the ultrasound system 100. Processor 118 can detect non-use triggers based on user input.
[0055] Alternatively, a non-use trigger could be the disconnection of the ultrasound probe 102 from the console 106. For example, an operator could disconnect the ultrasound probe 102 from the console 106. The processor 118 could detect a non-use trigger based on the disconnection of the ultrasound probe 102 from the console 106.
[0056] Alternatively, the non-use trigger can be a user input via the input component of the ultrasound probe 102, indicating that the ultrasound probe 102 will not be used for ultrasound imaging. For example, an operator can interact with the input component of the ultrasound probe 102.
[0057] Alternatively, a non-use trigger could be a drop event of the ultrasonic probe 102. For example, an operator of the ultrasonic probe 102 might accidentally drop it, causing a drop event. In this case, the processor 118 could detect the non-use trigger based on the drop event. For example, the processor 118 could receive sensor data from the sensors of the ultrasonic probe 102 and determine that the sensor data meets a threshold indicating a drop event of the ultrasonic probe 102. The sensor data could be acceleration data, rotation data, velocity data, etc.
[0058] like Figure 8 As further shown, method 800 may include controlling the movement of the transducer of the ultrasound probe between a neutral position and an offset position based on the detection of the non-use trigger (operation 804). For example, processor 118 may control the transducer 104 of ultrasound probe 102 to move from a neutral position to an offset position.
[0059] The neutral position can be a position where the axis of the ultrasound probe 102 is substantially parallel to the axis of the transducer 104. For example, the neutral position can be a position with an axis offset of 0°, 2°, or 5°. Alternatively, the neutral position can be a predefined position of the transducer 104. The offset position can be a position where the axis of the ultrasound probe 102 is substantially offset from the axis of the transducer 104. For example, the offset position can be a position with an axis offset of 20°, 25°, 30°, 40°, 45°, 60°, 70°, 90°, or 100°. Additionally or alternatively, the offset position can be a position substantially offset from the neutral position. For example, the offset position can be 20°, 25°, 30°, 40°, 45°, 60°, 70°, 90°, 100°, etc., offset from the neutral position.
[0060] According to one embodiment, processor 118 may transmit a signal to controller 602 of ultrasound probe 102, causing controller 602 to control mobile device 604 to move transducer 104 from a neutral position to an offset position. Alternatively, processor 118 may transmit a signal to mobile device 604, causing mobile device 604 to move transducer 104 from a neutral position to an offset position. Alternatively, controller 602 may control mobile device 604 to move transducer 104 from a neutral position to an offset position.
[0061] According to the implementation scheme, the ultrasonic probe 102 can maintain the transducer 104 in the offset position until a use trigger is detected and / or a signal is received that causes the transducer 104 to move from the offset position to the neutral position. After the ultrasonic probe 102 is disconnected from the control console, the ultrasonic probe 102 can maintain the transducer 104 in the offset position. Additionally or alternatively, the ultrasonic probe 102 can maintain the transducer 104 in the offset position after the ultrasonic system 100 is powered off.
[0062] In this way, the rotating frame 306 can protect the transducer 104 from external impacts on the ultrasonic probe 102, because the rotating frame 306 is in the position where the transducer 104 would normally be while it is still in a neutral position.
[0063] although Figure 8 Specific operations and sequences of operations are described, but it should be understood that other implementations may include those related to... Figure 8 The different operations and / or operations arranged differently are shown.
[0064] Figure 9 This is a flowchart of an example method 900 for controlling the movement of an ultrasound probe transducer between an offset position and a neutral position based on detection using a trigger. Operation of method 900 may be performed by one or more components of console 106. However, in other embodiments, one or more operations of method 900 may be performed by one or more components of ultrasound probe 102.
[0065] like Figure 9 As shown, method 900 may include detecting a use trigger (operation 902) indicating the use of an ultrasound probe. For example, processor 118 may detect a use trigger indicating the use of ultrasound probe 102. A use trigger may be a trigger indicating the use of ultrasound probe 102. As used herein, "use" may mean that ultrasound probe 102 is currently used for ultrasound imaging, intended for ultrasound imaging, etc.
[0066] Alternatively, the use trigger can be user input via the ultrasound probe 102 through the user input device 116, which selects the ultrasound probe 102 for ultrasound imaging via the ultrasound system 100. For example, an operator can interact with the user input device 116 to input user input that selects the ultrasound probe 102 for ultrasound imaging. The processor 118 can detect the use trigger based on the user input.
[0067] Alternatively, a use trigger may be the removal of the ultrasound probe 102 from the probe holder 126 of the ultrasound system 100. For example, an operator may remove the ultrasound probe 102 from the probe holder 126 of the ultrasound system 100 before performing ultrasound imaging. The processor 110 may detect the use trigger based on the removal of the ultrasound probe 102 from the probe holder 126. For example, the processor 118 may detect the use trigger based on signals received from sensors of the ultrasound system 100, tracking data received from an external tracking system, or signals received from the ultrasound probe 102, indicating that the ultrasound probe 102 has been removed from the probe holder 126.
[0068] Alternatively, the use trigger may be based on contact between the subject and the ultrasound probe 102. For example, before performing ultrasound imaging, an operator may position the ultrasound probe 102 so that it contacts the subject. The processor 118 may detect the use trigger based on the presence of contact between the subject and the ultrasound probe 102. For example, the processor 118 may detect the use trigger based on signals received from sensors of the ultrasound system 100, tracking data received from an external tracking system, or signals received from the ultrasound probe 102, which indicate that the ultrasound probe 102 is in contact with the subject.
[0069] Alternatively, the use trigger may be contact between the operator and the ultrasound probe 102. For example, the operator may contact the ultrasound probe 102 before performing ultrasound imaging. The processor 118 may detect the use trigger based on the presence of contact between the operator and the ultrasound probe. For example, the processor 118 may detect the use trigger based on signals received from sensors of the ultrasound system 100, based on tracking data received from an external tracking system, based on signals received from the ultrasound probe 102, etc., indicating that the ultrasound probe 102 is in contact with the operator.
[0070] Alternatively, the use trigger can be the position of the ultrasound probe 102 relative to the ultrasound system 100. For example, between ultrasound imaging sessions, the operator can position the ultrasound probe 102 in a position that indicates the use of the ultrasound probe 102 for ultrasound imaging. The processor 118 can detect the use trigger based on the position of the ultrasound probe 102 relative to the ultrasound system 100. For example, the processor 118 can detect the use trigger based on signals received from sensors of the ultrasound system 100, tracking data received from an external tracking system, or signals received from the ultrasound probe 102, which indicate the position of the ultrasound probe 102 relative to the ultrasound system 100.
[0071] Alternatively, the trigger can be a time frame. For example, a time frame could be the scheduled scan time for the subject, a time of day, a day of the week, etc. The processor 118 can detect the trigger based on the time frame.
[0072] Alternatively, the use trigger can be a user input via user input device 116 that activates the ultrasound system 100. For example, an operator can interact with user input device 116 to activate the ultrasound system 100. Processor 118 can detect the use trigger based on the user input.
[0073] Alternatively, the trigger can be user input via an input component of the ultrasound probe 102, which instructs the ultrasound probe 102 to be used for ultrasound imaging. For example, an operator can interact with the input component of the ultrasound probe 102.
[0074] like Figure 9 As further shown, method 900 may include controlling the movement of the transducer of the ultrasound probe between an offset position and a neutral position based on the detection of the use trigger (operation 904).
[0075] According to one embodiment, processor 118 may transmit a signal to controller 602 of ultrasound probe 102, causing controller 602 to control mobile device 604 to move transducer 104 from an offset position to a neutral position. Alternatively, processor 118 may transmit a signal to mobile device 604, causing mobile device 604 to move transducer 104 from an offset position to a neutral position. Alternatively, controller 602 may control mobile device 604 to move transducer 104 from an offset position to a neutral position.
[0076] According to the implementation scheme, the ultrasonic probe 102 can maintain the transducer 104 in a neutral position until a non-use trigger is detected and / or a signal is received that causes the transducer 104 to move from the neutral position to an offset position.
[0077] although Figure 9 Specific operations and sequences of operations are described, but it should be understood that other implementations may include those related to... Figure 9 The different operations and / or operations arranged differently are shown.
[0078] In this way, some embodiments herein provide an ultrasonic probe including a transducer capable of moving between a neutral position and an offset position based on the detection of a non-use trigger or an use trigger. Specifically, the transducer can be controlled to move to the offset position based on the detection of a non-use trigger. The transducer can remain in the offset position until it is controlled to move to the neutral position based on the detection of a use trigger. In the offset position, the transducer may be less susceptible to damage from external impacts compared to when it is in the neutral position. In this way, the ultrasonic probe of this disclosure is more robust than ultrasonic probes that include a fixed transducer. Therefore, this disclosure provides an improved ultrasonic probe and a technical improvement in the field of ultrasonic imaging technology.
