Description

Technical Field

[0002] As more and more people keep pets, take better care of them, and pay more and more attention to their health, pet heart examinations have become an increasingly common examination in pet hospitals. There are also more and more studies on the hearts of pets (dogs, cats, etc.), and more and more corresponding literature and data are available.

[0003] But for most veterinarians, cardiac ultrasound is a relatively "new" technology. They all know which sections and measurements to take during cardiac ultrasound, but their understanding of what the measurement results mean and how they correspond to the pet's heart performance varies.

[0045] 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.

[0046] 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.

[0047] 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).

[0048] like Figure 1 As shown, the ultrasonic imaging device provided by the present invention includes an ultrasonic probe 30, a transmitting / receiving control circuit 40 (i.e., a transmitting circuit 410 and a receiving circuit 420), a beamforming module 50, an IQ demodulation module 60, a processor 20, a human-computer interaction device 70 and a memory 80.

[0049] The ultrasonic probe 30 includes a transducer (not shown in the figure) composed of a plurality of array elements arranged in an array, wherein the plurality of array elements are arranged in a row to form a linear array, or arranged in a two-dimensional matrix to form a surface array, or the plurality of array elements can also form a convex array. The array elements are used to transmit ultrasonic waves according to the excitation electrical signal, or to convert the received ultrasonic waves into electrical signals. Therefore, each array element can be used to realize the mutual conversion between the electrical pulse signal and the ultrasonic wave, so as to realize the transmission of ultrasonic waves to the target object 10, and can also be used to receive the echo of the ultrasonic wave reflected back by the tissue. When performing ultrasonic detection, the transmitting circuit 410 and the receiving circuit 420 can be used to control which array elements are used to transmit ultrasonic waves and which array elements are used to receive ultrasonic waves, or control the array elements to transmit ultrasonic waves or receive ultrasonic waves in time slots. The array elements participating in ultrasonic emission can be excited by electrical signals at the same time, thereby transmitting ultrasonic waves at the same time; or the array elements participating in ultrasonic emission can also be excited by several electrical signals with a certain time interval, thereby continuously transmitting ultrasonic waves with a certain time interval.

[0050] The transmitting circuit 410 is used to generate a transmitting sequence according to the control of the processor 20. The transmitting sequence is used to control some or all of the multiple array elements to transmit ultrasonic waves to the target object. The transmitting sequence parameters include the array element position, the number of array elements and the ultrasonic beam transmission parameters (such as amplitude, frequency, number of transmissions, transmission interval, transmission angle, waveform, focus position, etc.) used for transmission. In some cases, the transmitting circuit 410 is also used to phase delay the transmitted beam so that different transmitting array elements transmit ultrasonic waves at different times so that each transmitted ultrasonic beam can be focused on a predetermined area of ​​interest. Different working modes, such as B image mode, C image mode and D image mode (Doppler mode), may have different transmitting sequence parameters. After the echo signal is received by the receiving circuit 420 and processed by subsequent modules and corresponding algorithms, a B image reflecting the anatomical structure of the tissue, a C image reflecting the blood flow information and a D image reflecting the Doppler spectrum image can be generated.

[0051] The receiving circuit 420 is used to receive the ultrasonic echo signal from the ultrasonic probe 30 and process the ultrasonic echo signal. The receiving circuit 420 may include one or more amplifiers, analog-to-digital converters (ADCs), etc. The amplifier is used to amplify the received echo signal after appropriate gain compensation, and the amplifier is used to sample the analog echo signal at a predetermined time interval to convert it into a digitized echo signal, and the digitized echo signal still retains amplitude information, frequency information, and phase information. The data output by the receiving circuit 420 can be output to the beamforming module 50 for processing, or output to the memory 80 for storage.

[0052] The beamforming module 50 is connected to the receiving circuit 420 signal, and is used to perform beamforming processing such as corresponding delay and weighted summation on the echo signal. Since the distances from the ultrasonic receiving point in the measured tissue to the receiving array element are different, the channel data of the same receiving point output by different receiving array elements have delay differences, and delay processing is required to align the phases and perform weighted summation on the different channel data of the same receiving point to obtain the ultrasound image data after beamforming. The ultrasound image data output by the beamforming module 50 is also called radio frequency data (RF data). The beamforming module 50 outputs the radio frequency data to the IQ demodulation module 60. In some embodiments, the beamforming module 50 may also output the radio frequency data to the memory 80 for caching or storage, or directly output the radio frequency data to the processor 20 for image processing.

[0053] The beamforming module 50 may perform the above functions in the form of hardware, firmware or software. The beamforming module 50 may be integrated in the processor 20 or may be separately provided, which is not limited in the present invention.

[0054] The IQ demodulation module 60 removes the signal carrier through IQ demodulation, extracts the tissue structure information contained in the signal, and performs filtering to remove noise. The signal obtained at this time is called a baseband signal (IQ data pair). The IQ demodulation module 60 outputs the IQ data pair to the processor 20 for image processing. In some embodiments, the IQ demodulation module 60 also outputs the IQ data pair to the memory 80 for caching or storage, so that the processor 20 reads the data from the memory 80 for subsequent image processing.

[0055] The IQ demodulation module 60 may also perform the above functions in the form of hardware, firmware or software. In some embodiments, the IQ demodulation module 60 may also be integrated with the beamforming module 50 in one chip.

[0056] The processor 20 is configured to be a central controller circuit (CPU), one or more microprocessors, a graphics controller circuit (GPU) or any other electronic component that can process input data according to specific logical instructions. It can control peripheral electronic components according to input instructions or predetermined instructions, or read and / or save data from the memory 80. It can also process the input data by executing the program in the memory 80, for example, performing one or more processing operations on the collected ultrasound data according to one or more working modes. The processing operations include but are not limited to adjusting or limiting the form of ultrasound waves emitted by the ultrasound probe 30, generating various image frames for subsequent display of the human-computer interaction device 70, or adjusting or limiting the content and form displayed on the display, or adjusting one or more image display settings displayed on the display (such as ultrasound images, interface components, and positioning areas of interest).

[0057] As echo signals are received, the acquired ultrasound data may be processed by the processor 20 in real time during scanning, or may be temporarily stored on the memory 80 and processed in quasi-real time in either on-line or off-line operation.

[0058] In this embodiment, the processor 20 controls the operation of the transmitting circuit 410 and the receiving circuit 420, for example, controls the transmitting circuit 410 and the receiving circuit 420 to work alternately or simultaneously. The processor 20 can also determine a suitable working mode according to the user's selection or the setting of the program, form a transmission sequence corresponding to the current working mode, and send the transmission sequence to the transmitting circuit 410, so that the transmitting circuit 410 uses the suitable transmission sequence to control the ultrasound probe 30 to transmit ultrasound waves.

[0059] The processor 20 is also used to process the ultrasound data to generate a grayscale image of signal strength changes within the scanning range, which reflects the anatomical structure inside the tissue, called a B image. The processor 20 can output the B image to the display of the human-computer interaction device 70 for display.

[0060] The human-computer interaction device 70 is used for human-computer interaction, such as outputting visual information and receiving user input. The user input can be received by a keyboard, operation button, mouse, trackball, touchpad, etc., or a touch screen integrated with a display; the visual information can be output by a display.

[0061] The memory 80 is used to store the above-mentioned various types of data.

[0062] The ultrasonic imaging device provided by the present invention also has an intelligent analysis function. When the ultrasonic imaging device examines the target object, it performs corresponding measurement items. After the measurement results are obtained, certain prompt information is given for the existing measurement results, or the existing measurement results are recalculated, and then certain prompt information is given according to the calculation results to prompt the doctor whether the target tissue currently being examined is normal or has possible problems. The following are some embodiments for detailed description.

[0063] The intelligent analysis function can be turned on by default, or it can be turned on by default in a teaching scenario. For example, the ultrasound imaging device is provided with ultrasound teaching software (such as iScanhelper). When the ultrasound teaching software is turned on, an instruction for starting intelligent analysis is generated, thereby turning on the intelligent analysis function. The input device is provided with a first button, and when the first button is triggered, an instruction for starting intelligent analysis is generated. For example, in a clinical scenario (ultrasound teaching software is not turned on), the user can turn the intelligent analysis function on and off through the first button. In actual use, the user can also turn on / off the function at any time.

[0064] The process of ultrasonic imaging equipment performing intelligent analysis functions is as follows Figure 2 As shown, the following steps are included:

[0065] Step 1, the processor 20 obtains the measurement results of the measurement items in the current ultrasonic examination. The measurement results of some measurement items can determine the diagnosis results alone, and some measurement items need to be determined together with the measurement results of other measurement items to determine the diagnosis results. Therefore, the processor 20 can specifically obtain the measurement results of a single target measurement item in the current ultrasonic examination, wherein a single measurement item pre-associated with a first diagnostic judgment condition and a first diagnostic result prompt information is a single target measurement item. The processor 20 can also obtain the measurement results of a target measurement item group in the current ultrasonic examination, wherein a measurement item group pre-associated with a second diagnostic judgment condition and a second diagnostic result prompt information is a target measurement item group, and the measurement item group includes multiple (two or more) measurement items. If the measurement results of two or more measurement items are required to determine the diagnosis result, then these measurement items constitute a measurement item group.

[0066] In this embodiment, step 1 specifically includes:

[0067] Step 11: Based on the scanning operation of the user, the processor 20 controls the ultrasonic probe 30 through the transmitting / receiving control circuit 40 to scan the target tissue of the target object to obtain an ultrasonic image of one or more sections of the target tissue. The target object can be a human or an animal. In this embodiment, dogs and cats are used as examples for description. The target tissue can be various types of organs, parts, etc. of the target object. In this embodiment, the heart is used as an example for description.

[0068] Step 12: After obtaining the ultrasound image, the user may perform manual measurement, for example, the processor 20 obtains the measurement results of the measurement items that have been measured based on the user's measurement operation on the ultrasound image of the one or more sections. Of course, the measurement may also be performed automatically, for example, the processor 20 automatically measures the ultrasound image of the one or more sections to obtain the measurement results of the measurement items that have been measured.

[0069] Step 2: The processor 20 determines whether the measurement result of the measurement item satisfies the associated diagnosis determination condition, and if so, outputs the associated first diagnosis result prompt information.

[0070] Specifically, the processor 20 determines whether the measurement result of a single target measurement item meets the associated first diagnostic judgment condition. If it meets the condition, the associated first diagnostic result prompt information is output. If it does not meet the condition, it indicates that the single target measurement item may not be abnormal or the diagnostic result cannot be obtained, and no processing is required. During the same inspection process of the same target object, the same measurement item may be measured multiple times, and the results will be saved in a preset measurement result library. A maximum of N measurement items can be saved in one inspection, and the N latest results will be retained when there are more than N items. N is an integer greater than 1. In this embodiment, N is 6. When calling the measurement result for judgment, the processor 20 can use the preset measurement result calling rule, for example, the result of the last measurement among the N results can be used, the average value, maximum value or minimum value of all results can be used, and different measurement result calling rules can be selected according to different measurement items to achieve differentiated processing. The above-mentioned measurement result calling rules can be set by the user in advance.

[0071] In one embodiment, there may be multiple first diagnostic judgment conditions pre-associated with a single measurement item, and each first diagnostic judgment condition is associated with the type or breed of the target object. The first warning interval of each first diagnostic judgment condition is different. The processor 20 is also used to obtain the type information (such as dog, cat, etc.) or breed information (such as Corgi, Husky, etc.) of the target object. Then, when judging the measurement result, the corresponding first diagnostic judgment condition is adopted. Specifically, the processor 20 judges whether the measurement result of a single target measurement item satisfies the first diagnostic judgment condition associated with the type information or breed information of the target object, and if so, outputs the associated first diagnostic result prompt information. There are large differences between animals of different types, and there are also large differences between different breeds of some animals (such as dogs). Therefore, the warning intervals corresponding to the same diagnostic result are likely to be different. Therefore, setting suitable first diagnostic judgment conditions for animals of different types or different breeds in advance can more accurately judge the diagnostic result.

[0072] In one embodiment, the first diagnostic judgment condition includes: the measurement result is in a preset first warning interval, for example, the measurement result satisfies a preset first inequality. The first inequality corresponds to the first warning interval. A single measurement item can be associated with a set of first diagnostic judgment conditions and first diagnostic result prompt information, or it can be associated with multiple sets of first diagnostic judgment conditions and first diagnostic result prompt information. For example, a single measurement item is the left ventricular posterior wall thickness at end diastole (LVPWd), and its associated set of first diagnostic judgment conditions and first diagnostic result prompt information are: LVPWd < 0.3cm (first warning interval) and "ventricular volume overload"; its associated another set of first diagnostic judgment conditions and first diagnostic result prompt information are: LVPWd > 0.6cm and "myocardial hypertrophy".

[0073] The first diagnostic judgment condition may also include: the measurement result is substituted into the preset first intermediate quantity formula to obtain the first intermediate quantity, and the first intermediate quantity is in the preset first warning interval. For example, a single measurement item is the diastolic left ventricular internal diameter (LVIDd), and its associated first diagnostic judgment condition is: the measurement result of LVIDd is substituted into the preset first intermediate quantity formula LVIDDN = LVIDd / BW 0.294 The first intermediate value LVIDDN is obtained from the first warning interval LVIDDN>1.7, where BW is the weight of the target object. That is, after obtaining the measurement result of LVIDd, according to the formula LVIDDN=LVIDd / BW 0.294 LVIDDN is calculated. If LVIDDN is greater than 1.7, it means that the measurement result of LVIDd meets the first diagnosis judgment condition, and the associated first diagnosis result prompt information is output. The first diagnosis result prompt information may be: left ventricular dilatation.

[0074] When the measurement result of a single target measurement item meets the associated first diagnosis judgment condition, the processor 20 outputs the associated first diagnosis result prompt information, which can be specifically output to an external device or to an indicator light to prompt the user through the light signal of the indicator light, or to a speaker to prompt the user through the sound signal of the speaker, or by displaying the associated first diagnosis result prompt information on a display to prompt the user. This embodiment is described using the latter as an example.

[0075] In one embodiment, even if the intelligent analysis function is not turned on, the above judgment can be performed after obtaining the measurement results of the measurement items. After the processor 20 receives the instruction for starting the intelligent analysis, the associated first diagnostic result prompt information can be directly displayed on the display, and the response speed is very fast.

[0076] The processor 20 can also determine whether the measurement results of the target measurement item group meet the associated second diagnosis judgment condition. If so, the associated second diagnosis result prompt information is output. If not, it means that the target measurement item group may not be abnormal or the diagnosis result cannot be obtained, and no processing is required. Similarly, there can be multiple second diagnosis judgment conditions pre-associated with the measurement item group, and each second diagnosis judgment condition is associated with the type or variety of the target object. The second warning interval of each second diagnosis judgment condition is different. The processor 20 is also used to obtain the type information or variety information of the target object. Then, when judging the measurement result, the corresponding second diagnosis judgment condition is used. Specifically, the processor 20 determines whether the measurement results of the target measurement item group meet the second diagnosis judgment condition associated with the type information or variety information of the target object. If so, the associated second diagnosis result prompt information is output.

[0077] In one embodiment, the second diagnosis determination condition may include: the measurement result of any measurement item in the measurement item group is in the second warning interval corresponding to the measurement item. Assuming that the measurement item group includes two measurement items A and B, the measurement result of A is in the second warning interval corresponding to A, and the measurement result of B is in the second warning interval corresponding to B, then it is considered that the measurement item group meets the corresponding second warning interval.

[0078] The second diagnostic judgment condition may also include: the measurement results of all measurement items in the measurement item group are substituted into the preset second intermediate quantity formula to obtain the second intermediate quantity, and the second intermediate quantity is in the preset second warning interval. For example, a measurement item group includes: pre-ejection time PEP and left ventricular ejection time LVET. The second diagnostic judgment condition associated with the measurement item group is: PEP and LVET are substituted into the second intermediate quantity formula R1=PEP / LVET to obtain the second intermediate quantity R1, and the second warning interval is R1≥0.3. The second diagnostic result prompt information associated with the measurement item group may be "reduced preload, abnormal myocardial contraction". For another example, a measurement item group includes: the width LA at the widest part of the left atrium and the width Ao at the widest part of the aorta. The second diagnostic judgment condition associated with the measurement item group is: LA and Ao are substituted into the second intermediate quantity formula LA / Ao to obtain the second intermediate quantity, and the second warning interval is LA / Ao>1.5. The second diagnostic result prompt information associated with the measurement item group may be "left atrial dilatation"; of course, the second warning interval may vary depending on the type of target object, as shown in the following table:

[0079] Animal species The second warning zone Diagnosis result prompt information cat LA / Ao>1.5 Left atrial dilatation dog LA / Ao>1.6 Left atrial dilatation

[0080] When the measurement results of the target measurement item group meet the associated second diagnosis judgment condition, the processor 20 outputs the associated second diagnosis result prompt information, which can be specifically output to an external device or to an indicator light to prompt the user through the light signal of the indicator light, or to a speaker to prompt the user through the sound signal of the speaker, or by displaying the associated second diagnosis result prompt information on a display to prompt the user. This embodiment is described using the latter as an example.

[0081] In one embodiment, even if the intelligent analysis function is not turned on, the above judgment can be performed after obtaining the measurement results of the measurement items. After the processor 20 receives the instruction for starting the intelligent analysis, the associated second diagnostic result prompt information can be directly displayed on the display, and the response speed is very fast.

[0082] The ultrasonic imaging device provided by the present invention also supports the user to select the measurement results to be involved in the determination calculation from the preset measurement library, how to calculate the measurement results, how to compare the results after calculation, and how to calculate again. The system has a built-in measurement formula editor (conventional calculation, scientific calculation formula), and the user can specify the measurement results corresponding to each calculation item in the formula. The following is a detailed introduction.

[0083] The processor 20 is also used to receive an instruction for opening the editing of the diagnostic judgment condition, and in response to the instruction, display the editing interface through the display. For example, the input device is provided with a corresponding key, which can be a physical key or a virtual key. When the user presses this key, an instruction for opening the editing of the diagnostic judgment condition is issued, and the editing interface can be seen on the display, such as Figure 3 shown.

[0084] Furthermore, based on the user's operation on the editing interface, the processor 20 can add, modify or delete the association between a single measurement item, the first diagnostic judgment condition and the first diagnostic result prompt information, and can also add, modify or delete the association between the measurement item group, the second diagnostic judgment condition and the second diagnostic result prompt information.

[0085] Specifically, Figure 3As shown, the editing interface may be provided with: an item selection bar a for providing multiple measurement items for the user to select, a formula editor b for editing formulas, and an input bar c for the user to input diagnostic result prompt information. For the association between the newly added measurement items, the diagnostic judgment conditions, and the diagnostic result prompt information, the user can select the measurement items in the item selection bar, and can select only one or multiple items to form a measurement item group. The user can use the formula edited by the formula editor to determine the warning interval, which also determines the diagnostic judgment conditions, and the user can input the diagnostic result prompt information. That is, the processor 20 determines the measurement item selected by the user in the item selection column through the input device; determines the formula edited by the user using the formula editor based on the selected measurement item through the input device, and the formula is used to determine the warning interval; receives the diagnosis result prompt information input by the user through the input device; and then associates the selected measurement item, the warning interval determined by the edited formula, and the input diagnosis result prompt information. If the user only selects one measurement item, the association obtained is the association relationship between the single measurement item, the first diagnosis judgment condition, and the first diagnosis result prompt information; if the user selects multiple (two or more) measurement items, the association obtained is the association relationship between the measurement item group, the second diagnosis judgment condition, and the second diagnosis result prompt information. For example, if the user wants to add an analysis function for evaluating myocardial contraction in dogs, he can first select the measurement items (PEP and LVET) to be evaluated in the item selection column a (measurement library). The measurement library can classify the menu according to cardiac measurement-canine applicability, and then use the formula editor to select the calculation formula "division", specify the dividend as PEP and the divisor as LVET, then the calculation formula is R1 = PEP / LVET, and then select the "threshold judgment" rule, set R1 greater than or equal to 0.3 to trigger a diagnostic result prompt message, and then enter the prompt message as "reduced preload, abnormal myocardial contraction". Finally, save this association relationship.

[0086] The editing interface also has a check button for triggering the processor 20 to check the formula edited by the user to check whether the formula is correct or not, and to feed back the check result (correct or incorrect).

[0087] The ultrasonic imaging device may also include a communication module, such as a communication interface, a wireless communication module, etc., for communicating with an external device. The processor 20 may receive and save the association between a single measurement item, a first diagnostic judgment condition, and a first diagnostic result prompt information transmitted by an external device through the communication module, or may receive and save the association between a measurement item group, a second diagnostic judgment condition, and a second diagnostic result prompt information transmitted by an external device through the communication module. For example, the external device may be other ultrasonic imaging devices, various types of computers, smart phones, and other terminals with data processing capabilities. The external device may also have Figure 2The functions shown in the figure take mobile terminals such as smartphones as an example, which can obtain the measurement results of the measurement items from the ultrasonic imaging equipment and then use Figure 2 The method shown displays the corresponding diagnostic result prompt information on the screen, which is convenient for other doctors to remotely understand the patient's condition. The mobile terminal also has the above-mentioned editing interface. The doctor can edit the relationship between the measurement items, diagnostic judgment conditions and diagnostic result prompt information on the mobile terminal and transmit it to the ultrasonic imaging device, allowing the doctor to work more flexibly and expanding the applicable scenarios of the ultrasonic imaging device.
