This disclosure is a continuation of International Application No. PCT/CN2020/071098, filed on Jan. 9, 2020, which claims priority to Chinese Patent Application No. 201910133780.X, filed on Feb. 22, 2019. Both of the aforementioned disclosures are hereby incorporated by reference in their entireties.
Embodiments of the present disclosure relate to ultrasound data transmission technology and, in particular, to a multi-ultrasound imaging device.
An ultrasound imaging method is widely used in clinical diagnosis and becomes a first choice for clinical diagnosis of various diseases. The ultrasound imaging method controls an ultrasonic probe to transmit and receive signals through a host of an ultrasound imaging device to accomplish the purpose of ultrasound imaging.
With the development of science and technology, researchers continue to improve an ultrasound imaging system and obtain an ultra-high-speed ultrasound imaging system that can support the requirement of ultra-high-speed imaging.
There are many differences between the ultrasound imaging system and the ultra-high-speed ultrasound imaging system. For example, the ultrasound imaging system mostly uses a line scan method for transmission, reception and imaging, while the ultra-high-speed ultrasound imaging system mostly uses a plane wave method for transmission, reception and imaging. For another example: the ultrasound imaging system and the ultra-high-speed ultrasound imaging system use different numbers of array elements and different imaging modes during operation, so that the excitation voltage of the ultrasonic probe is not completely consistent. In addition, the ultrasonic probe corresponding to a design of the ultra-high-speed ultrasound imaging system also has different requirements.
If it can be compatible with the ultra-high-speed ultrasound imaging system based on the original ultrasound imaging device, it can even support other ultrasound imaging systems presented in subsequent development, and can fully and effectively multiplex the components of the original ultrasound imaging device and provide an ultrasound imaging system with good compatibility, compact design and low cost, which will have very important and realistic scientific and economic value.

The processor 10 is configured to receive an ultrasound system setting instruction input by a user, so that an ultrasound system 20 of the N ultrasound systems 20 is in an enabled state.
The ultrasound system in the enabled state is configured to send a control instruction to the ultrasonic probe 40 via the communication channel 30.
The ultrasonic probe 40 is configured to cooperate with the ultrasound system in the enabled state to operate according to the control instruction.
In this embodiment, the ultrasound imaging device includes N ultrasound systems 20, where the ultrasound imaging device including two ultrasound systems 20 is taken as an example for description in this embodiment. The two ultrasound systems are: a first ultrasound system and a second ultrasound system.
The ultrasound system setting instruction may be an ultrasound system setting instruction input by the user in real time according to current needs. For example, when the user currently needs to use the first ultrasound system, an instruction which can enable the first ultrasound system to be in the enabled state is input to the processor 10, and if the user would use the second ultrasound system then, an instruction that can enable the second ultrasound system to be in an enabled state would be input to the processor. The ultrasound system setting instruction may also be a use flow of the first ultrasound system and the second ultrasound system set by the user. For example, the time periods, during which the first ultrasound system and the second ultrasound system are in the enabled state, are set respectively. Where the first ultrasound system and the second ultrasound system cannot be in the enabled state at the same time, that is, the first ultrasound system and the second ultrasound system cannot be used at the same time.
After the processor 10 obtains the ultrasound system setting instruction input by the user, a current operating system of the ultrasound imaging device is determined according to the ultrasound system setting instruction, where the current operating system is the ultrasound system in the enabled state of the two ultrasound systems 20 of the ultrasound imaging device, the control instruction corresponding to the ultrasound system in the enabled state is generated, and the control instruction is sent to the ultrasound system in the enabled state.
Optionally, the ultrasound imaging device may further include: a control channel 50.
The control channel 50 is configured to transmit the control instruction to the ultrasound system in the enabled state.
It can be understood that the processor 10 can send the control instruction to the first ultrasound system or the second ultrasound system using the same control channel 50, or send the control instruction to the first ultrasound system or the second ultrasound system using mutually independent control channels 50. When the same control channel 50 is used, the control channel 50 may be a high-speed serial computer expansion bus standard (Peripheral Component Interconnect Express, PCIe) cable or a USB interface. When the mutually independent control channels 50 are used, the mutually independent control channels 50 may be PCIe cables or USB interfaces at the same time, or one of them is a PCIe cable and the other is a USB interface.
If the first ultrasound system receives the control instruction sent by the processor 10, and the first ultrasound system is in the enabled state, according to the control instruction, a state control instruction that can control the operating state of the ultrasonic probe 40 to correspond to the first ultrasound system is generated, and the communication channel 30 is controlled to perform channel configuration, so that it can send the state control instruction corresponding to the first ultrasound system to the ultrasonic probe 40. If the second ultrasound system receives the control instruction sent by the processor 10, and the second ultrasound system is in the enabled state, according to the control instruction, a state control instruction that can control the operating state of the ultrasonic probe 40 to correspond to the second ultrasound system is generated, and the communication channel 30 is controlled to perform channel configuration, so that it can send the state control instruction corresponding to the second ultrasound system to the ultrasonic probe 40.
After receiving the state control instruction, the ultrasonic probe 40 cooperates with the ultrasound system in the enabled state to work according to the state control instruction.
In this embodiment, in the ultrasound imaging device provided with N ultrasound systems, a processor generates a control instruction that can instruct the current operating system of the ultrasound imaging device according to a user's setting instruction, and, through the control instruction, controls one ultrasound system of the N ultrasound systems to operate, that is, in the enabled state; and the ultrasound system in the enabled state generates a state control instruction according to the control instruction, and controls a communication channel for channel configuration, so that the configured communication channel can transmit the state control instruction generated by the ultrasound system in the enabled state to the ultrasonic probe, thereby controlling the ultrasonic probe perform the operation corresponding to the state control instruction. And the ultrasonic probe feeds back feedback information to the ultrasound system in the enabled state through a configured communication channel. It is realized that when N ultrasound systems operate separately, they can perform the transmission of the state control instruction and the feedback information through the same communication channel, so that the ultrasound imaging device does not need to set up a communication channel for each of the N ultrasound systems separately, which improves functional compatibility of the ultrasound imaging device, and reduces the cost and volume of manufacturing an ultrasound imaging device.
Optionally,
One side of the system multiplexing array 31 includes N groups of ports, where each group of ports is connected to an ultrasound system 20.
The system multiplexing array 31 is configured to send a state control instruction sent by the ultrasound system in the enabled state to the sensor control array 32.
The sensor control array 32 is configured to send the received state control instruction sent by the ultrasound system in the enabled state to the ultrasonic probe 40.
In this embodiment, the ultrasound system that receives the control instruction among the first ultrasound system and the second ultrasound system starts to operate. For example, if the first ultrasound system receives the control instruction, the first ultrasound system is in the enabled state, generates a state control instruction according to the control instruction, and controls the connection between the system multiplexing array 31 and the first ultrasound system, the connection state between the system multiplexing array 31 and the sensor control array 32, and the connection state between the sensor control array 32 and the ultrasonic probe 40. Therefore, the multiplexing array 31 and the sensor control array 32 can transmit the state control instruction generated by the first ultrasound system to the ultrasonic probe 40.
Optionally,
The system multiplexing control unit 311 is configured to control, according to the ultrasound system in the enabled state, a group of ports in the system multiplexing connecting unit 312 corresponding to the ultrasound system in the enabled state to connect with the ultrasound system in the enabled state in a communicational way.
Specifically, the system multiplexing connecting unit 312 includes the N groups of ports, and each group of ports is configured to connect with one of the N ultrasound systems 20.
When the ultrasound imaging device includes two ultrasound systems, that is, the ultrasound imaging device includes a first ultrasound system and a second ultrasound system, the system multiplexing control unit 311 is controlled by the ultrasound system in the enabled state in the first ultrasound system and the second ultrasound system, and the system multiplexing control unit 311 controls the connection state of the two ports in the system multiplexing connecting unit 312, to enable only one port of the two ports of the system multiplexing connecting unit 312 to be connected at the same time. Where the number of ports included in the system multiplexing connecting unit 312 is greater than or equal to the number of ultrasound systems included in the ultrasound imaging device. That is, the system multiplexing control unit 311 determines that the ultrasound system in the enabled state is the first ultrasound system, and the port, used to connect to the first ultrasound system among the ports of the system multiplexing connecting unit 312, is controlled to connect to the first ultrasound system. If the ultrasound system in the enabled state is determined to be the second ultrasound system, the port, used to connect to the second ultrasound system among the ports of the system multiplexing connecting unit 312, is controlled to connect to the first ultrasound system. Therefore, the system multiplexing array 31 can only receive the state control instruction sent by the first ultrasound system or the second ultrasound system at the same time, and send the state control instruction to the sensor control array 32.
Optionally,
Specifically, when the ultrasound system in the enabled state is the first ultrasound system, the first ultrasound system controls the system multiplexing control unit 311, so that the system multiplexing control unit 311 controls the switch in the system multiplexing connecting unit 312 to connect with the first ultrasound system. When the ultrasound system in the enabled state is the second ultrasound system, the system multiplexing control unit 311 controls the switch in the system multiplexing connecting unit 312 to connect to the second ultrasound system. In this way, the system multiplexing array 31 can be connected with the first ultrasound system or can also be connected with the second ultrasound system. In addition, through the system multiplexing array 31, the first ultrasound system and the second ultrasound system can operate in different transmitting, receiving, and imaging modes, and the first ultrasound system and the second ultrasound system are not affected by each other's excitation voltage.
Optionally,
The sensor control unit 321 is configured to control, according to the current operating system, operation of the sensor connecting unit 322 and the array element corresponding to the current operating system.
Specifically, the sensor control unit 321 is controlled by the ultrasound system in the enabled state, and the sensor control unit 321 controls the operating mode of the sensor connecting unit 322, that is, controls the array element corresponding to the ultrasound system in the enabled state in the sensor connecting unit 322 to operate, and transmits the state control instruction to the array element corresponding to the ultrasound system in the enabled state in the ultrasonic probe 40, to enable the array element to operate according to the state control instruction. It is realized that the state control instruction is sent to the array element corresponding to the ultrasound system in the enabled state through the sensor control array 32, so that the array element operates according to the state control instruction sent by the ultrasound system in the enabled state.
Optionally, the sensor connecting unit 322 is an array composed of a plurality of switches.
Specifically, the process of the sensor connecting unit 322 transmitting the state control instruction is that: the system multiplexing array 31 transmits the state control instruction to the sensor connecting unit 322 through an output port of the system multiplexing connecting unit 312, and after the sensor control array 32 receives the state control instruction, the state control instruction is sent to the ultrasonic probe 40 through the switch closed in the sensor connecting unit 322.
Optionally, the operating mode of the sensor connecting unit 322 is a one-to-many mode or a one-to-one mode; where the one-to-many mode represents that one switch in the sensor connecting unit 322 can be connected to at least two of the array elements; and the one-to-one mode represents that one switch of the sensor connecting unit 322 is connected to one of the array elements.
When it is determined that the current operating system is the second ultrasound system, the working principle and process of the sensor connecting unit 322 can refer to the description when the current operating system is the first ultrasound system, which will not be repeated here.
Optionally, the N ultrasound systems 20 in the ultrasound imaging device may be mutually independent hardware systems.
Optionally, the N ultrasound systems 20 in the ultrasound imaging device can be integrated on the same hardware system.
Optionally, the ultrasound imaging device further includes: a display device.
The processor is configured to detect whether the ultrasonic probe 40 connect with the communication channel 30 in a communicational way; and if the ultrasonic probe is not connected with the communication channel in a communicational way, control the display device to display reminder information.
The display device is configured to display reminder information, and the reminder information is configured to remind that the ultrasonic probe 40 is not connected with the communication channel 30.
Specifically, the communication channel 30 may be configured to transmit a state signal, the state signal represents the operating state of the ultrasonic probe 40, and different operating states correspond to different state signals. For example, when the ultrasonic probe 40 is not connected with the communication channel 30, the state signal is 00; when operating according to the state control instruction of the first ultrasound system, the state signal is 01; and when operating according to the state control instruction of the second ultrasound system, the state signal is 10. Where the operating state of the ultrasonic probe 40 is that the ultrasonic probe 40 is not connected with the communication channel 30, or operates according to the state control instruction of the first ultrasound system, or operates according to the state control instruction of the second ultrasound system.
When the ultrasonic imaging device system is initialized, the operating state of the ultrasonic probe 40 needs to be detected firstly. Where the communication channel 30 can actively transmit the state signal to the processor 10, and the processor 10 judges the operating state of the ultrasonic probe 40 according to the received state signal; and an inquiry signal can be also sent to the ultrasonic probe 40 through the processor 10. There are different response signals for different operating status of the ultrasonic probe 40, and the processor 10 judges the operating state of the ultrasonic probe 40 according to the received response signal.
When the processor 10 detects that the ultrasonic probe 40 is not connected with the communication channel 30, a reminder information is displayed on the display to remind the user that the ultrasonic probe 40 is not connected to the communication channel 30, and the ultrasonic probe 40 needs to be connected with the communication channel 30.
