[0054] In order to achieve the purpose of being more portable, portable ultrasound imaging equipment is set as a handheld terminal product. The portable ultrasound imaging equipment removes modules such as the display and control panel, and only retains basic functions such as energy storage, ultrasound imaging and communication. Therefore, the portable ultrasound imaging equipment needs to be connected to a terminal device with a display function (such as a mobile phone, tablet and traditional ultrasound equipment with a display function) to achieve complete ultrasound imaging.

[0055] The portable ultrasonic imaging device can be connected to different terminal devices to achieve ultrasonic imaging. The portable ultrasonic imaging device and the terminal device have relatively independent power supply modules, resulting in different remaining battery life of the portable ultrasonic imaging device and the terminal device. The two need to work together, so the lower remaining battery life of the portable ultrasonic imaging device and the terminal device determines the usage time of the ultrasonic imaging work.

[0056] In view of this, in this embodiment, the portable ultrasonic imaging device and the terminal device, which are independently powered, are configured to be able to charge and discharge each other. An energy storage management module is provided in the portable ultrasonic imaging device, and the energy storage management module can control the portable ultrasonic imaging device to charge the terminal device, or control the terminal device to charge the portable ultrasonic imaging device, so as to balance the remaining battery life between the portable ultrasonic imaging device and the terminal device, and finally improve the use time of the ultrasonic imaging work.

[0057] Of course, an energy storage management module is set in the terminal device, and the energy storage management module in the terminal device can also control the portable ultrasonic imaging device to charge the terminal device, or control the terminal device to charge the portable ultrasonic imaging device, so as to balance the remaining battery life between the portable ultrasonic imaging device and the terminal device. Alternatively, the energy storage management module in the portable ultrasonic imaging and the energy storage management module in the terminal device can coordinately control the mutual charging between the portable ultrasonic imaging device and the terminal device, so as to balance the remaining battery life between the portable ultrasonic imaging device and the terminal device.

[0058] During the charging process of a portable ultrasonic imaging device, especially during wireless charging, the frequency used in transmitting charging power overlaps with the frequency range of echoes received by the portable ultrasonic imaging device during ultrasonic imaging, causing the portable ultrasonic imaging device to generate electromagnetic interference to the echo signal during charging, thereby degrading the image performance of ultrasonic imaging.

[0059] In this embodiment, three solutions are provided to eliminate the electromagnetic interference of charging on the echo signal, and the solutions are as follows:

[0060] The first one: physical isolation eliminates interference, and the charging module and the module receiving echo signals in the ultrasound host are relatively far apart. For example, the charging module and the module receiving echo signals are arranged at opposite ends of the ultrasound host to increase the distance between them, so as to reduce or avoid electromagnetic interference of the charging module to the module receiving echo signals during charging; or, a physical shielding structure is provided between the internal charging module and the module receiving echo signals, for example, an electromagnetic shielding cover is provided between the two, so as to reduce or avoid electromagnetic interference of the charging module to the module receiving echo signals during charging by means of physical blocking.

[0061] The second solution is to eliminate interference by staggering the timing. The charging of the ultrasound host and the ultrasound imaging scan are staggered, that is, ultrasound imaging scan is not performed during charging, and ultrasound imaging scan is not performed during charging, so that there is no electromagnetic interference caused by charging during ultrasound imaging scan.

[0062] The third solution: Data processing to eliminate interference. After the ultrasound host receives the echo signal interfered by electromagnetic interference, it filters the echo signal and removes the interference signal in the echo signal to ensure the imaging quality of the ultrasound image.

[0063] The above solutions can be selected from one or more of them and combined into a portable ultrasonic imaging device.

[0064] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0065] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0066] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0067] In one embodiment, a portable ultrasonic imaging device is provided. The portable ultrasonic imaging device can be a palm-held terminal. The portable ultrasonic imaging device may not include components such as a display module and a control panel. The portable ultrasonic imaging device only includes basic functions such as ultrasonic scanning, energy storage charging, and signal communication. This makes the portable ultrasonic imaging device have a smaller size and greatly improves portability. For example, a user can carry the portable ultrasonic imaging device with him.

[0068] When the portable ultrasonic imaging device performs ultrasonic imaging detection, it needs to work in conjunction with a terminal device with a display function to achieve a complete ultrasonic imaging function. The terminal device can be a mobile phone, a tablet computer, a traditional desktop ultrasonic device or a traditional portable ultrasonic device. The terminal device can also have a stronger image processing capability than the portable ultrasonic imaging device to achieve higher definition ultrasonic imaging.

[0069] The portable ultrasonic imaging device has a bidirectional charging function, which can realize mutual charging between the portable ultrasonic imaging device and the terminal device to balance the remaining battery life of the portable ultrasonic imaging device and the terminal device, and ultimately increase the collaborative working time of the portable ultrasonic imaging device and the terminal device.

[0070] Please refer to Figure 1 The portable ultrasonic imaging device of this embodiment mainly includes an ultrasonic host 1. The ultrasonic host 1 can be used to connect the ultrasonic probe 2 and the terminal device 3 in a wired or wireless manner. The ultrasonic host 1 is connected to the ultrasonic probe 2 and receives the ultrasonic echo signal sent by the ultrasonic probe. The ultrasonic host 1 generates the first ultrasonic image data based on the ultrasonic echo signal. The ultrasonic host 1 is connected to the terminal device 3 and can send the first ultrasonic image data to the terminal device 3. The terminal device 3 processes the first ultrasonic image data into an ultrasonic image and displays it. Of course, the first ultrasonic image data generated by the ultrasonic host 1 based on the ultrasonic echo signal can also be directly used for imaging display. For example, the ultrasonic host 1 can process ultrasonic images with relatively low clarity and directly display them to the terminal device 3, which can meet the use of ordinary scenes such as home use.

[0071] The ultrasound host 1 can be a handheld terminal product, which is convenient for users to hold and use. The weight of the ultrasound host 1 is not more than 500g, and the dimensions of the ultrasound host 1 meet at least one of the following conditions: the length is not more than 200mm, the width is not more than 100mm, and the height is not more than 50mm. The length and width of the ultrasound host 1 can be the same or similar to the length and width of the existing mobile phone, so as to facilitate holding the ultrasound host 1 and the mobile phone stacked up and down, and facilitate wireless charging and discharging between the ultrasound host 1 and the mobile phone.

[0072] Please refer to Figure 1 The ultrasound host 1 mainly includes a first ultrasound imaging module 11, a first energy storage module 12 and a first energy storage management module 13. The first ultrasound imaging module 11 includes at least a control unit, an image processing unit and a communication unit, so that the first ultrasound imaging module 11 has control, processing and communication functions. The control unit of the first ultrasound imaging module 11 is used to control the ultrasound probe 1 to transmit ultrasound waves and receive ultrasound echoes. The control unit of the first ultrasound imaging module 11 is also used to control the reception of ultrasound echo information; the image processing unit of the first ultrasound imaging module 11 generates first ultrasound image data based on ultrasound echo signal processing; the communication unit of the first ultrasound imaging module 11 includes one or both of wired communication and wireless communication, and the communication unit of the first ultrasound imaging module 11 is used to transmit the generated first ultrasound image data to the terminal device 3 by wire or wireless means.

[0073] The first energy storage module 12 may include an energy storage battery. The first energy storage module 12 is used to store electrical energy, and the first energy storage module 12 can be charged and discharged. The first energy storage module 12 is used to provide electrical energy to the ultrasound host 1 .

[0074] The first energy storage management module 13 may include a charge and discharge control unit. The first energy storage management module 13 is connected to the first energy storage module 12, and the charge and discharge control unit of the first energy storage management module 13 is used to control the charging and discharging of the first energy storage module 12; the first energy storage management module 13 may also be connected to the first ultrasonic imaging module 11, and the first energy storage management module 13 controls the first energy storage module 12 to provide electrical energy to the ultrasonic probe 2.

[0075] The first ultrasonic imaging module 11, the first energy storage module 12 and the first energy storage management module 13 can be set as relatively independent components, connected by data lines or power lines. The first ultrasonic imaging module 11, the first energy storage module 12 and the first energy storage management module 13 can also be integrated into an integrated structure and connected by wiring on a circuit board.

[0076] In one embodiment, the first energy storage management module 13 may further include a charging and discharging module, and the charging and discharging module of the first energy storage management module 13 may include one or both of a wireless charging coil and a wired charging and discharging interface. The charging and discharging module of the first energy storage management module 13 connects the first energy storage module 12 to a power source to realize charging and discharging of the first energy storage module 12.

[0077] In one embodiment, the charging and discharging control units in the first ultrasonic imaging module 11 and the first energy storage management module 13 may be combined into one control management module.

[0078] In this embodiment, the first energy storage management module 13 is used to control the charging and discharging of the first energy storage module 12, including: when the ultrasound host 1 is connected to the terminal device 3, the first energy storage management module 13 is used to control the first energy storage module 12 to release electric energy to the terminal device 3; or, the first energy storage management module 13 is used to control the terminal device 3 to release electric energy to the first energy storage module 12, so as to balance the remaining battery life between the ultrasound host 1 and the terminal device 3, that is, to make the remaining battery life of the ultrasound host 1 and the remaining battery life of the terminal device 3 equal or approximately equal.

[0079] The ultrasound host 1 has a bidirectional charging function, the ultrasound host 1 can charge the terminal device 3, and the terminal device can also charge the ultrasound host 1. The ultrasound host 1 can also have a unidirectional charging function, for example, the ultrasound host 1 can charge the terminal device 3, or the terminal device can also charge the ultrasound host 1. The ultrasound host 1 can also have a unidirectional charging function to meet the needs of some usage scenarios. For example, when the maximum power of the first energy storage module 12 set in the ultrasound host 1 is greater than the maximum power of the terminal device 3 (a small terminal such as a mobile phone), when the ultrasound host 1 and the terminal device 3 work together, the power of the terminal device 3 is generally used up first, so the unidirectional charging of the ultrasound host 1 to the terminal device 3 can balance the remaining battery life between the ultrasound host 1 and the terminal device 3. For another example, when the maximum power of the first energy storage module 12 set in the ultrasound host 1 is less than the maximum power of the terminal device 3 (a large terminal such as a tablet), when the ultrasound host 1 and the terminal device 3 work together, the power of the ultrasound host 1 is generally used up first, so the unidirectional charging of the terminal device 3 to the ultrasound host 1 can balance the remaining battery life between the ultrasound host 1 and the terminal device 3.

[0080] The first energy storage management module 13 is used to calculate and compare the remaining battery life of the ultrasound host 1 and the remaining battery life of the terminal device 3; based on the comparison result, the first energy storage management module 13 controls the first energy storage module 12 to release electric energy to the terminal device 3; or, controls the terminal device 3 to release electric energy to the first energy storage module 12. For example, when more electric energy is stored in the ultrasound host 1 and the remaining battery life of the ultrasound host 1 is greater than the remaining battery life of the terminal device 3, the first energy storage management module 13 is used to control the first energy storage module 12 to release electric energy to the terminal device 3; when more electric energy is stored in the terminal device 3 and the remaining battery life of the terminal device 3 is greater than the remaining battery life of the ultrasound host 1, the first energy storage management module 13 is used to control the terminal device 3 to release electric energy to the first energy storage module 12.

[0081] The first energy storage management module 13 can calculate the remaining endurance time by the following formula:

[0082] T=E / V

[0083] Among them, T is the remaining battery life, E is the current power, and V is the current power consumption rate.

[0084] The first energy storage management module 13 mainly detects the discharge current of the first energy storage module 12 and the discharge current of the terminal device 3. By detecting the discharge current, the consumed electric energy can be calculated, that is, the current power E can be calculated. The current power consumption rate V is calculated by the difference between the power at the previous moment and the current power. The current consumption rate = (power at the previous moment - current power) / time difference between the two moments. Finally, the remaining battery life T is calculated by the formula T = E / V.

[0085] In one embodiment, if the terminal device 3 has built-in power monitoring and display, such as a mobile phone and a tablet computer with built-in monitoring and display of remaining power and remaining battery life, the first energy storage management module 13 can directly obtain the remaining battery life information of the terminal device 3, and the first energy storage management module 13 does not need to monitor the power of the terminal device 3.

[0086] In one embodiment, the terminal device 3 may be provided with a second energy storage management module, and the second energy storage management module of the terminal device 3 may execute the control of the first energy storage management module 13, that is, when the ultrasound host 1 is connected to the terminal device 3, the second energy storage management module is used to control the first energy storage module 12 to release electric energy to the terminal device 3; or, the second energy storage management module is used to control the terminal device 3 to release electric energy to the first energy storage module 12 to balance the remaining battery life between the ultrasound host 1 and the terminal device 3. In other words, the first energy storage management module 13 may not be provided in the ultrasound host 1, and the charging and discharging control is performed by the second energy storage management module of the terminal device 3. Of course, the ultrasound host 1 may also retain the first energy storage management module 13, and the first energy storage management module 13 and the second energy storage management module cooperate to execute control to balance the remaining battery life between the ultrasound host 1 and the terminal device 3, for example; the first energy storage management module 13 is used to control the first energy storage module 12 to release electrical energy to the terminal device 3, and the second energy storage management module is used to control the terminal device 3 to release electrical energy to the first energy storage module 12; or, one of the first energy storage management module 13 and the second energy storage management module executes charging and discharging control, and the other serves as a backup.

[0087] In one embodiment, the first energy storage management module 13 is provided with a remaining battery life threshold value, and the remaining battery life threshold value serves as a trigger value for judging the charge and discharge balance. If the threshold value is not reached, it indicates that both the ultrasound host 1 and the terminal device 3 have sufficient power to perform ultrasonic imaging detection. If the threshold value is reached, it indicates that one of the ultrasound host 1 and the terminal device 3 has too low power, triggering mutual charging between the ultrasound host 1 and the terminal device 3 to achieve a balance in the remaining battery life, thereby increasing the duration of collaborative working of the ultrasound host 1 and the terminal device 3.

[0088] The principle of triggering the ultrasound host 1 and the terminal device 3 to charge each other according to the remaining endurance time threshold is as follows:

[0089] If the remaining battery life of the ultrasound host 1 is less than the remaining battery life threshold of the ultrasound host 1, the first energy storage management module 13 is controlled to control the terminal device 3 to release power to the ultrasound host 1; if the remaining battery life of the terminal device 3 is less than the remaining battery life threshold of the terminal device 3, the ultrasound host 1 is controlled to release power to the terminal device 3.

[0090] For example, the remaining battery life threshold is set to 10 minutes. If the remaining battery life of the ultrasound host 1 is less than 10 minutes and the remaining battery life of the terminal device 3 is greater than 10 minutes, the terminal device 3 is controlled to release power to the ultrasound host 1; if the remaining battery life of the terminal device 3 is less than 10 minutes and the remaining battery life of the ultrasound host 1 is greater than 10 minutes, the ultrasound host 1 is controlled to release power to the terminal device 3.

[0091] In one embodiment, the remaining battery life threshold may also be set in the terminal device 3 , and the second energy storage management module in the terminal device 3 controls the terminal device 3 to release power to the ultrasound host 1 , and controls the ultrasound host 1 to release power to the terminal device 3 .

[0092] In one embodiment, the first energy storage management module 13 includes a wireless charging and discharging management module, and the wireless charging and discharging management module may include a wireless charging coil. The ultrasound host 1 with the wireless charging and discharging management module can be wirelessly charged and discharged with the terminal device 3 with the corresponding wireless charging and discharging management module. The use of wireless charging and discharging can stack the ultrasound host 1 and the terminal device 3 up and down, reduce the use of cables, and facilitate user operation.

[0093] Please refer to Figure 2 In one embodiment, the ultrasound host 1 further includes a wired power interface 14, which can be connected to the terminal device 3 via a cable 4, and the ultrasound host 1 and the terminal device 3 can realize wired charging and discharging via the cable 4. The wired power interface 14 can also serve as a communication interface, so that the cable 4 can also transmit information such as the first ultrasound image data.

[0094] Two wired power interfaces 14 can be provided, one of which is used to connect to the terminal device 3 via a cable 4, and the other wired power interface 14 can be connected to a mobile power supply or a fixed power supply via a cable, so that when the ultrasound host 1 and the terminal device 3 are connected to work together, the ultrasound host 1 can also be charged, and the terminal device 3 can be indirectly charged to increase the remaining battery life.

[0095] The ultrasound host 1 may include one of a wireless charging and discharging management module and a wired power interface 14 to achieve wired or wireless charging and discharging. The ultrasound host 1 may also include a wireless charging and discharging management module and a wired power interface 14 to achieve wired and wireless charging and discharging, giving users more charging options.

[0096] Please refer to Figure 3In one embodiment, the ultrasound host 1 may further include a sending and receiving module 15, the ultrasound host 1 is connected to the ultrasound probe 2 through the sending and receiving module 15, the sending and receiving module 15 is used to control the transmission and reception of the ultrasound probe 2, and the first ultrasound imaging module 11 can receive the ultrasound echo signal through the sending and receiving module 15.

[0097] The first energy storage management module 13 and the transmitting and receiving module 15 in the ultrasound host 1 are electromagnetically shielded from each other, so that the first energy storage management module 13 will not generate electromagnetic interference to the ultrasonic echo signal received by the transmitting and receiving module 15 during the charging and discharging process.

[0098] The ultrasonic host 1 may be a rectangular structure, and has a first end and a second end opposite to each other in the length direction. The first end of the ultrasonic host 1 is used for connection with the terminal device 3, and the second end of the ultrasonic host 1 is used for connection with the ultrasonic probe 2. The first energy storage management module 13 is located at the first end of the ultrasonic host 1, and the transmitting and receiving module 15 is located at the second end of the ultrasonic host 1. The first energy storage management module 13 and the transmitting and receiving module 15 are located at both ends of the ultrasonic host 1. The first energy storage management module 13 and the transmitting and receiving module 15 are relatively far apart, so that charging and discharging occur at the first end of the ultrasonic host 1, and receiving the ultrasonic echo signal occurs at the second end of the ultrasonic host 1, which can avoid the electromagnetic interference of charging and discharging on the receiving ultrasonic echo signal as much as possible.

[0099] In one embodiment, an electromagnetic shielding structure may be provided in the ultrasound host 1, and the electromagnetic shielding structure is provided between the first energy storage management module 13 and the transmitting and receiving module 15. The electromagnetic shielding structure separates the first energy storage management module 13 and the transmitting and receiving module 15 by physical isolation. For example, the first energy storage management module 13 is located at the first end of the ultrasound host 1, the transmitting and receiving module 15 is located at the second end of the ultrasound host 1, and the electromagnetic shielding structure is located in the middle of the ultrasound host 1. The electromagnetic shielding structure includes an electromagnetic shielding cover or an electromagnetic shielding film, which may be made of metal, and the electromagnetic shielding cover or the electromagnetic shielding film can shield electromagnetic interference to eliminate electromagnetic interference to the received ultrasonic echo signal during the charging and discharging process.

[0100] In one embodiment, the ultrasound host 1 sets the transmitting and receiving module 15 to transmit and receive and the first energy storage management module 13 to charge and discharge at different time sequences, that is, the ultrasound host 1 sets the transmitting and receiving module 15 to transmit and receive and the first energy storage management module 13 to charge and discharge cannot be performed at the same time. When the transmitting and receiving module 15 of the ultrasound host 1 is in the transmitting and receiving operation, it cannot be charged and discharged even if an external power supply is connected; when the ultrasound host 1 and the terminal device 3 are in a state of mutual charging and discharging, or when the ultrasound host 1 is connected to the external power supply and is in a charging state, the transmitting and receiving module 15 cannot perform the transmitting and receiving operation. By staggering the timing, when the transmitting and receiving module 15 is in the transmitting and receiving operation, there is no electromagnetic interference caused by charging and discharging, thereby ensuring the quality of the received ultrasonic echo signal.

[0101] In one embodiment, when the first ultrasonic imaging module 11 of the ultrasonic host 1 generates first ultrasonic image data based on the ultrasonic echo signal, it includes performing data processing operations such as filtering processing to eliminate interference signals generated by charging and discharging, so that the first ultrasonic image data does not include interference data, and the quality of the ultrasonic image can also be guaranteed.

[0105] The plug 22 of the ultrasonic probe 2 is adapted to be connected with the probe interface 16. The ultrasonic probe 2 may include a variety of different models. For example, the ultrasonic probe 2 may be a linear array probe or a planar array probe. Different models of ultrasonic probes 2 are used for different parts of the body. Different models of ultrasonic probes 2 are detachably connected to the ultrasonic host 1. The user can select the desired ultrasonic probe 2 to be connected to the ultrasonic host 1 for use as needed.

[0106] The ultrasound host 1 and the ultrasound probe 2 may also be configured as an integral non-detachable structure, for example, the probe 21 of the ultrasound probe 2 is directly connected to the transmitting and receiving module 15 in the ultrasound host 1 via a cable; or, the probe 21 of the ultrasound probe 2 is directly fixed to the outer shell of the ultrasound host 1.
