Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first" and "second," and the like in the description and claims of the present invention and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not set forth for a listed step or element but may include steps or elements not listed.
In an embodiment of the present invention, an ultrasound contrast imaging method is provided, referring to fig. 1, the method including:
s101, setting multiple contrast agent types and corresponding imaging modes.
Ultrasound contrast agents are used in ultrasound contrast imaging to enhance the blood supply visualization of tissues or lesions. Generally, the micro-encapsulated microbubbles with micron-sized diameters enter a blood circulation system through intravenous injection to enhance the reflection of ultrasonic waves so as to achieve the purpose of ultrasonic contrast imaging. The different types of contrast agents have different diameter ranges of microbubbles, different coating thicknesses and different viscoelasticity, so that the receiving and transmitting parameters of the ultrasonic equipment in the imaging process are different, and the imaging effects are different.
In embodiments of the present invention, a plurality of contrast agent types that can satisfy existing contrast agent categories and corresponding imaging modalities are provided, the imaging modalities including parameters, algorithms and/or procedures that are adapted to the contrast agent type. For example, for a contrast agent with a contrast agent type of Sono Vue, the matching imaging mode adapts the configuration parameters of the contrast agent, such as the transmit frequency parameter, the receive bandwidth parameter, etc., or the imaging mode may adapt the imaging algorithm of the contrast agent, or the imaging mode may be packaged into a program to adapt the imaging process of the contrast agent. It should be noted that one or more of parameters, algorithms and procedures suitable for the type of contrast agent may be included in the imaging mode, as long as ultrasonic imaging of the contrast agent can be achieved.
After the type of the contrast agent is determined, an imaging mode corresponding to the type of the contrast agent needs to be set, and tests can be performed according to physical characteristics of the contrast agents of different types, so that configuration parameters of ultrasonic imaging performed by various contrast agents, such as transmission frequency, pulse transmission sequence, receiving bandwidth and the like, can be obtained. Or an imaging algorithm, an imaging program, etc., or an imaging algorithm may be generated according to the configuration parameters, for example, a processing link, or the parameters or the imaging algorithm may be directly packaged into a computer program. After the contrast agent type and the corresponding imaging mode are obtained, the contrast agent type and the corresponding imaging mode can be stored in a local device or a network device, so that the contrast agent type and the corresponding imaging mode can be conveniently applied to an ultrasonic imaging device in the follow-up process.
S102, external input information is obtained, the type of the contrast agent is determined, and the contrast agent is matched with a target imaging mode.
Due to the fact that multiple types of contrast agents and corresponding imaging modes are set, before ultrasonic contrast imaging is carried out, the types of the contrast agents need to be determined according to acquired external input information, the imaging mode corresponding to the types of the contrast agents needs to be matched in the existing imaging modes, and the imaging modes are recorded as target imaging modes.
The following two determination modes of the target imaging mode are included in the embodiments of the present invention, but are not limited to:
the first method is to acquire a preset external input signal, determine the type of the contrast agent according to the corresponding relation between the preset external input signal and the type of the contrast agent, and match the target imaging mode.
In this manner, the preset external input signal may be understood as a signal having a correspondence relationship with the type of the contrast agent. The preset external input signal is acquired based on an information receiving module of the ultrasonic diagnostic equipment, for example, the preset external data signal is received through a touch screen of the ultrasonic diagnostic equipment, at this time, a pull-down menu or a plurality of virtual keys of a contrast agent type are presented on the touch screen for a user to operate, and a signal triggered by the user through clicking the pull-down menu or the virtual keys on the touch screen is the preset external output signal. For another example, when the user operates the keyboard and the trackball of the ultrasound device, the signal generated by the cooperation of the keyboard and the trackball can also be used as the preset external data signal. The embodiment of the present invention does not specifically limit the information receiving module of the ultrasonic diagnostic apparatus.
And after the preset external input signal is obtained, determining the type of the contrast agent according to the corresponding relation between the preset external input signal and the type of the contrast agent. For example, a way of presenting a pull-down menu on a touch screen is described, if a first-level menu of the pull-down menu is to please select contrast agent information, after a user clicks the first-level menu, a second-level menu is presented on the touch screen, where the second-level menu includes a first contrast agent, a second contrast agent, and a third contrast agent, and if the user clicks the second contrast agent, the click signal is used as a preset external input signal, and then the second contrast agent having a corresponding relationship with the signal is used as a determined contrast agent type, and is further matched with a target imaging mode.
And secondly, acquiring external input information, analyzing the external input information according to a preset algorithm to obtain the type of the contrast agent, and matching a target imaging mode.
In this method, the contrast agent type may be obtained only by analyzing external input information, for example, the external input information is voice information, and the corresponding contrast agent type may be obtained only by recognizing and extracting the voice information according to a preset voice extraction algorithm, or for example, the external input information is picture information, and the preset algorithm at this time is an image recognition algorithm, and image recognition or text information extraction is required for the picture information to obtain the contrast agent type. It should be noted that the picture information may include one or more of a text label of a contrast agent, a trademark picture, a barcode, or two-dimensional code information. For example, if external input information, that is, image information of a contrast agent, is acquired through a camera connected to an ultrasonic diagnostic device, the image is identified by using a preset image identification algorithm, then it is determined whether the image contains information capable of representing the type of the contrast agent, and if contrast agent two-dimensional code information is obtained through detection, the two-dimensional code information is matched with the type of the contrast agent, so that a target imaging mode is obtained.
In addition, the external data information also includes gesture information, since most users of the ultrasonic diagnostic equipment are professional doctors or image operators, for the needs of hygiene and diagnosis, the users usually have medical gloves, and at this time, signals cannot be input through a capacitive touch screen, the gesture information of the users can be acquired based on a mobile sensing device of the ultrasonic diagnostic equipment, and then the gesture information is analyzed through a preset gesture information recognition algorithm to obtain a target imaging mode. That is, the preset algorithm in the embodiment of the present invention can be matched with different external input modules of the ultrasound diagnostic apparatus, but the above-mentioned voice recognition algorithm is matched with the sound receiving module of the ultrasound diagnostic apparatus, and is used for recognizing and analyzing the received voice information, but the present invention does not limit the kind of the preset algorithm, and a plurality of preset algorithms can be included to meet the analysis requirements of different input information.
And S103, carrying out ultrasonic contrast imaging according to the target imaging mode.
After the target imaging mode is obtained, the ultrasonic diagnostic equipment can adjust the working mode of an imaging module in the ultrasonic diagnostic equipment according to parameter information, an algorithm or a program and the like in the target imaging mode, so that contrast imaging is realized.
The invention provides an ultrasonic contrast imaging method, which is characterized in that a target imaging mode matched with a contrast agent is determined according to contrast agent information, then imaging is carried out according to the target imaging mode, respective imaging modes can be matched according to different contrast agents, and the use requirements of different contrast agents are met.
Correspondingly, on the basis of the above embodiment of the ultrasound contrast imaging method, in another embodiment of the present invention, the method may further include generating a prompt message, specifically:
in response to the failure to resolve the contrast agent type from the external input information or the failure to match to the target contrast mode according to the contrast agent type, the method further comprises:
selection prompt information is generated for prompting a user of failed resolution, failed matching, and/or selection of one of a plurality of contrast agent types currently set.
That is, when the target contrast pattern cannot be matched based on the external input information, the system generates the prompt information, which mainly prompts the user that the target contrast pattern cannot be matched, but the prompt information may be presented in various forms, for example, a prompt information that the input information is failed to be identified, a prompt information that the contrast pattern cannot be matched, or a prompt information that directly prompts the user to select one contrast agent type from currently existing contrast agent types.
Correspondingly, in response to the contrast agent type and/or the corresponding imaging mode not being set, the ultrasound contrast imaging method further includes:
setting prompt information is generated for prompting a user to set a contrast agent type and/or a corresponding imaging mode.
When the method is used for inputting contrast agent related information, if the current ultrasound imaging system or ultrasound diagnostic apparatus does not set a contrast agent type or a corresponding imaging mode, the user is prompted to perform setting of the contrast agent related information, for example, setting of the contrast agent type, and setting of the imaging mode of the contrast agent, which may include setting of corresponding imaging parameters, algorithms, and/or programs. When the input ends based on the user are different, the interfaces presented by the prompt information are different, if the user inputs the prompt information based on the touch screen of the ultrasonic equipment, the prompt information is displayed on the touch screen of the ultrasonic equipment, and if the user inputs the prompt information based on the network equipment, such as an intelligent terminal, the prompt information is displayed on the intelligent terminal.
For example, after a plurality of contrast agent types and corresponding imaging modes are set in the ultrasound imaging device, in the ultrasound imaging system supporting voice recognition, if a user needs to switch the contrast agent imaging mode, the ultrasound imaging device may switch to the contrast agent imaging parameters or algorithm link required by the user after correctly recognizing the voice command for contrast agent mode imaging switching by issuing a specific voice instruction. When the contrast agent type input by the user is not the stored contrast agent type, the user is reminded that the contrast agent cannot be identified, and the current default contrast agent imaging mode is adopted or the user is reminded to set the imaging mode corresponding to the contrast agent type.
If the ultrasonic imaging device comprises the code scanning device, a user can face the bar code of the package of the contrast agent to the code scanning device, and after the code scanning device successfully acquires the bar code, the bar code is switched to a corresponding contrast agent imaging mode.
Correspondingly, if the ultrasonic imaging device includes an image recognition device such as a camera, a user may face a contrast agent packing box or a bottle of contrast agent to the camera of the ultrasonic device, at this time, the external information acquired through the camera is the image information of the contrast agent packing box or the bottle, and then the image information is recognized and switched to a corresponding contrast agent imaging mode, and if the external information cannot be recognized or cannot be matched with the imaging mode, prompt information is generated to prompt the user to adopt a default contrast agent imaging mode.
It should be noted that, when setting a plurality of contrast agent types and corresponding imaging modes, the setting may be performed based on a local setting or based on a web server. If a plurality of contrast agent types and corresponding imaging modes are directly set in the ultrasound diagnostic apparatus, when the country and region to which the ultrasound diagnostic apparatus is facing are known and the contrast agent type used in the country or region is known, the contrast agent type and the corresponding imaging mode may be set as default information, and the other contrast agent types and the corresponding imaging modes may be set as alternative information. Before the ultrasonic diagnostic equipment is used, a user can send an imaging mode setting instruction to the corresponding network end equipment, and then the network end equipment outputs a corresponding imaging mode program to the ultrasonic diagnostic equipment to set the imaging mode of the contrast agent.
There is also provided in an embodiment of the present invention an ultrasound contrast imaging system, see fig. 2, comprising:
a storage unit 201 for storing a plurality of contrast agent types and corresponding imaging modalities comprising parameters, algorithms and/or programs adapted to the contrast agent types.
The storage unit is arranged at a local device or a network server end, wherein the local device can be an ultrasonic diagnosis device or a local computer, and the network server end can be a cloud server or a remote debugging terminal.
For different contrast agent imaging, the ultrasound diagnostic apparatus supports the following operations:
the method comprises the following steps of performing clinical tests on each different contrast agent, presetting corresponding optimal contrast imaging transmitting and receiving parameters, even an independent algorithm module, and ensuring that the imaging effect of each contrast agent is optimal;
the ultrasonic diagnostic equipment supports user configuration default entering of an imaging mode, and supports parameters, algorithm links, programs and the like corresponding to the imaging mode.
Besides the ultrasonic diagnostic equipment, the storage unit can also be arranged at a network server side, and the network server side can be in communication connection with the ultrasonic diagnostic equipment and can also be in communication connection with a local computer. If the communication connection is carried out with the ultrasonic diagnosis equipment, the ultrasonic diagnosis equipment is required to be provided with a communication module, and the network server side can send the set type of the contrast agent and the corresponding imaging mode to the ultrasonic diagnosis equipment. Or the ultrasonic signals can be sent to a local computer, and then sent to the ultrasonic diagnostic equipment by the local computer based on a wireless transmission mode, a Bluetooth transmission mode or a wired transmission mode.
The network server comprises a computer and a mobile device, that is, the settings of the contrast agent type and the corresponding imaging mode can be stored by the computer of the network terminal or the mobile device. For example, when the storage is performed by the computer, the setting request may be sent to the computer and the computer may respond. Of course, for convenience and modification of setting, the corresponding setting information can be stored in the mobile terminal of operation maintenance personnel or product testing personnel, so that the setting request can be responded in time, and the unsuitable imaging mode can be modified or set in time.
An obtaining unit 202, configured to obtain external input information.
In the intelligent ultrasonic diagnostic apparatus, the external information may be acquired by a voice acquisition device, an image acquisition device, a code scanning acquisition device, a mobile sensing device, and the like, and the specific type of the input device of the ultrasonic diagnostic apparatus in the embodiment of the present invention is not limited. When there are a plurality of information acquisition devices, the information acquisition devices respond only to an external input device that has information input. However, for example, when there is input information simultaneously in the camera, the voice device, and the code scanning gun in the peripheral input, the selection is performed according to the result of the most occurrence among the three, or the response priority may be set, and the external input devices simultaneously existing may be selected in order of priority. Specifically, the voice acquisition device may adopt a microphone array, the image acquisition device may adopt a camera, the code scanning acquisition device may be a code scanning gun, the mobile sensing device may include a camera and an infrared sensor, the above devices may be integrated on the ultrasonic diagnostic equipment, and may also be used as an external input device to be connected with the ultrasonic diagnostic equipment in a wired or wireless manner, and the specific embodiment form and the connection mode are not limited.

Specifically, the acquiring unit 202 acquires a preset external input signal generated by an external operation, and the matching unit 203 determines the contrast agent type according to the corresponding relationship between the preset external input signal and the contrast agent type, and matches the target imaging mode from the storage unit 201.

Correspondingly, the obtaining unit 202 obtains external input information, and the matching unit 203 analyzes the external input information according to a preset algorithm to obtain the type of the contrast agent, and matches the target contrast mode from the storage unit.
The acquisition unit 202 at this time may be an image acquisition device, a sound acquisition device, and/or a movement sensing device, corresponding to the ultrasonic diagnostic apparatus. If the acquisition unit is a sound acquisition device, the acquired external input information is voice information output by a user, then the voice information is identified according to a voice identification algorithm to obtain corresponding identification information, and then the type of the contrast agent is obtained according to the identification information.
