Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a first flowchart of an ultrasound contrast imaging one-key optimization method according to an embodiment of the present application.
The one-key optimization method for ultrasonic contrast imaging provided by the embodiment of the application can comprise the following steps:
step S101: and acquiring the imaging frame rate and the real-time imaging depth of the target ultrasonic imaging equipment in the ultrasonic imaging process.
In practical application, the imaging frame rate and the real-time imaging depth of the target ultrasonic imaging device in the ultrasonic imaging process can be obtained first, and it should be noted that the imaging frame rate in the application is also the imaging frame rate of the target ultrasonic imaging device applied in real time.
In a specific application scenario, the ultrasound imaging adjustment method provided by the application can be matched with a one-key optimization key set for a user, namely, after the user triggers the one-key optimization key of the target ultrasound imaging device, the steps of acquiring the imaging frame rate, the real-time imaging depth and the later steps of the target ultrasound imaging device in the ultrasound imaging process can be executed.
It should be noted that in a specific application scenario, a one-key optimization button may be set on the target ultrasound imaging device, so that the user only needs to trigger the one-key optimization button, and the target ultrasound imaging device may automatically execute the one-key optimization method for ultrasound imaging provided in the present application, and of course, other manners may also be used to trigger the one-key optimization method for ultrasound imaging provided in the present application, which is not specifically limited herein.
Step S102: the transmit timing of the target ultrasound contrast device is adjusted based on the imaging frame rate.
In practical application, because the imaging frame rate is affected by the transmitting time sequence, and the transmitting time sequence can affect the signal-to-noise ratio of the contrast agent, for example, the more the ultrasonic transmitting times in unit time are, the more the signal acquisition of the contrast agent is, the better the signal-to-noise ratio of the contrast agent is, so after the imaging frame rate is acquired, the transmitting time sequence of the target ultrasonic contrast device can be adjusted based on the imaging frame rate, and the adjusted transmitting time sequence can meet the requirements of users more.
For convenience of understanding, assuming that the time of one frame of tissue imaging is FrameTimeTissue, K times of ultrasound waves need to be transmitted in total to form a frame of contrast image, and the time of completing 1 transceiving at a specific imaging depth is LetTime, frametimecontrast=lettime×k×n, N represents the number of pulses of a group of contrast imaging pulse sequences, that is, N pulses are transmitted at one time, then the total frame time of tissue+contrast is frametimetissue=frametimetissue+frametimecontrast, and assuming that the reference minimum frame rate under contrast is FrameRef, after the number of times of transmission is increased, the response of the number of times of transmission is correspondingly increased, so that after the transmission time sequence is adjusted, the imaging frame rate and the synthesis of the ultrasound contrast image are affected.
It should be noted that since the transmission timing will affect the signal-to-noise ratio of the contrast agent and the composition of the ultrasound contrast image, the transmission timing of the target ultrasound contrast device may be adjusted based on the imaging frame rate according to the actually required signal-to-noise ratio of the contrast agent, the user's requirements for the ultrasound contrast image.
Step S103: the real-time transmit frequency of the target ultrasound contrast device is adjusted based on the real-time imaging depth.
In practical application, when the imaging depth of the target ultrasonic imaging device is different, in order to ensure the performance requirements such as the definition of the ultrasonic imaging image, different emission frequencies are needed to perform imaging, so that the real-time emission frequency of the target ultrasonic imaging device can be adjusted based on the real-time imaging depth after the real-time imaging depth is acquired in order to ensure the performance of the ultrasonic imaging image.
It should be noted that the implementation sequence of the two steps of adjusting the transmission time sequence of the target ultrasound imaging apparatus based on the imaging frame rate and adjusting the real-time transmission frequency of the target ultrasound imaging apparatus based on the real-time imaging depth is not specifically limited in this application.
Step S104: and acquiring radio frequency signal data of the target ultrasonic imaging equipment in the ultrasonic imaging process.
Step S105: and adjusting the real-time receiving demodulation parameters of the target ultrasonic contrast device based on the radio frequency signal data.
In practical application, in the application process of the target ultrasonic imaging device, not only the transmission of ultrasonic waves, but also the receiving and imaging of ultrasonic waves are involved, and after the transmission process of ultrasonic waves is adjusted, in order to enable the receiving process of ultrasonic waves to be matched with the transmission process, the radio frequency signal data of the target ultrasonic imaging device in the ultrasonic imaging process can be obtained, and the real-time receiving demodulation parameters of the target ultrasonic imaging device are adjusted based on the radio frequency signal data. It should be noted that in this process, the real-time receive demodulation parameters of the target ultrasound contrast device may be adjusted based on the radio frequency signal data according to the user's performance requirements for the ultrasound contrast image.
Step S106: and re-performing ultrasonic contrast imaging based on the adjusted target ultrasonic contrast equipment to obtain a target ultrasonic contrast image.
In practical application, after the transmission time sequence, the real-time transmission frequency and the real-time receiving demodulation parameters of the target ultrasonic contrast device are adjusted, ultrasonic contrast imaging can be performed again based on the adjusted target ultrasonic contrast device, so that a target ultrasonic contrast image meeting the requirements is obtained.
According to the ultrasonic contrast imaging adjustment method, imaging frame rate and real-time imaging depth of the target ultrasonic contrast equipment in an ultrasonic contrast process are obtained; adjusting the emission time sequence of the target ultrasonic contrast device based on the imaging frame rate; adjusting the real-time transmitting frequency of the target ultrasonic contrast device based on the real-time imaging depth; acquiring radio frequency signal data of a target ultrasonic imaging device in an ultrasonic imaging process; adjusting the real-time receiving demodulation parameters of the target ultrasonic contrast device based on the radio frequency signal data; and re-performing ultrasonic contrast imaging based on the adjusted target ultrasonic contrast equipment to obtain a target ultrasonic contrast image. According to the method and the device, the transmitting time sequence of the target ultrasonic contrast device can be adjusted according to the imaging frame rate, the real-time transmitting frequency of the target ultrasonic contrast device is adjusted according to the real-time imaging depth, the real-time receiving demodulation parameters of the target ultrasonic contrast device are adjusted according to the radio frequency signal data, the adjustment of multiple parameters of the target ultrasonic contrast device is achieved, the imaging frame rate, the real-time imaging depth and the radio frequency signal data are all real-time generated data of the target ultrasonic contrast device in the ultrasonic contrast process, namely the adjustment of the target ultrasonic contrast device according to the data generated by the target ultrasonic contrast device in the operation process is achieved, in the prior art, a user needs to manually adjust the lower deflector TGC to conduct gain adjustment on the target ultrasonic contrast device, and therefore after changing one ultrasonic object, the user needs to adjust the lower deflector TGC again, the operation is complex, and the adjustment effect of each time is difficult to ensure to be consistent with the ultrasonic object.
In the method for adjusting ultrasound contrast imaging provided in the embodiment of the present application, in a working process of a target ultrasound contrast device, a user may determine an imaging frame rate range suitable for a current scanning object based on working experience, so a process of adjusting a transmission time sequence of the target ultrasound contrast device based on the imaging frame rate may specifically be: judging whether the imaging frame rate is larger than a corresponding minimum frame rate threshold value; if the imaging frame rate is greater than the minimum frame rate threshold, increasing the number of transmit pulses of the target ultrasound contrast device. Specifically, because the transmission of ultrasound and the like by different scanning objects are different due to the influence of the self tissue characteristics of the scanning objects, the required ultrasound frequency threshold value may be different when the scanning objects are scanned by ultrasound, that is, the minimum frame rate threshold value may correspond to the scanning objects, and the corresponding relation may be determined according to actual needs.
In practical applications, since the number of transmitted pulses includes the number of pulses transmitted by the target ultrasound imaging apparatus in a set of pulses, after increasing the number of transmitted pulses by the target ultrasound imaging apparatus, the number of pulses transmitted in a set of pulses increases, and the transmission timing corresponds to the number of transmitted pulses, so that the time of the transmission timing is prolonged, and accordingly, the imaging frame rate is also changed. It should be noted that in this process, the user may set the number of transmission pulses allowed to work for the target ultrasound imaging apparatus, and when the number of transmission pulses of the target ultrasound imaging apparatus is increased, the number of transmission pulses of the target ultrasound imaging apparatus may be adjusted in combination with the number of transmission pulses allowed to work set by the user for the target ultrasound imaging apparatus. And when the number of the transmission pulse of the target ultrasonic contrast device is increased, the number of the transmission pulse of the target ultrasonic contrast device can be increased according to the principle of increasing 1 at a time.
In the method for adjusting ultrasound contrast imaging provided in the embodiment of the present application, in a working process of a target ultrasound contrast imaging device, along with accumulation of working experience, a user may determine in advance an appropriate emission frequency at each imaging depth, and then a process of adjusting the real-time emission frequency of the target ultrasound contrast imaging device based on the real-time imaging depth may specifically be: acquiring a first corresponding relation of target ultrasonic contrast equipment, wherein the first corresponding relation is a corresponding relation between imaging depth and transmitting frequency; determining a target emission frequency corresponding to the real-time imaging depth based on the first corresponding relation; the value of the target transmission frequency is taken as the value of the real-time transmission frequency. In the process of acquiring the first corresponding relation of the target ultrasonic contrast device, the working mode of the target ultrasonic contrast device, and the imaging depth and the transmitting frequency corresponding to each working mode can be acquired; acquiring frequency points supported among transmitting frequencies corresponding to all working modes; according to the number of frequency points, the imaging depth between the corresponding working modes is divided in equal proportion, and an imaging depth section is obtained, wherein the range of the imaging depth section is inversely proportional to the number of the frequency points; and taking a frequency point corresponding to an imaging depth section with the imaging depth as a transmitting frequency value of the imaging depth.
Taking the working mode of the target ultrasonic contrast device as a high-penetration mode Pen, a general mode Gen and a high-resolution mode Res as examples, assuming that default imaging depths in three modes are respectively Depth_Pen, depth_Gen and Depth_Res, and emission frequencies are TxFreq_pen, txFreq_Gen and TxFreq_Res, when the value of the real-time imaging Depth is smaller than or equal to the Depth_pen, txFreq_pen can be used as the value of the target emission frequency; when the value of the real-time imaging Depth is larger than the depth_pen and smaller than the depth_Gen, a certain value between TxFreq_pen and TxFreq_Gen can be used as the value of the target emission frequency; when the value of the real-time imaging Depth is greater than or equal to the depth_gen and less than the depth_res, a certain value between txfreq_gen and txfreq_res can be used as the value of the target emission frequency; and when the value of the real-time imaging Depth is equal to or greater than the depth_res, txfreq_res may be taken as the value of the target emission frequency, or the like.
In practical applications, the target ultrasound imaging apparatus may support multiple emission frequencies, that is, the target ultrasound imaging apparatus may provide multiple frequency points for a user to select, where the emission frequency supported by the target ultrasound imaging apparatus may correspond to an imaging depth section actually required, that is, the first correspondence may include a correspondence between the imaging depth section and the emission frequency value.
It should be noted that, at this time, when determining the target emission frequency corresponding to the real-time imaging Depth based on the first correspondence, the corresponding target emission frequency may be determined according to the imaging Depth segment to which the real-time imaging Depth belongs, and still taking the target ultrasound imaging device supporting the three working modes as an example, assuming that the number of frequency points of the target ultrasound imaging device between txfreq_pen and txfreq_gen is N, and the number of frequency points of the target ultrasound imaging device between txfreq_gen and txfreq_res is M, when the value of the real-time imaging Depth is greater than and less than the depth_pen, the frequency point segment to which the target emission frequency belongs may be determined by the formula depth_cmp (i) =depth_pen+ (i-1) (depth_gen-depth_pen)/N, (i=1 … N), and the frequency point corresponding to the frequency point of the frequency point segment is regarded as the value of the target emission frequency; when the value of the real-time imaging Depth is greater than or equal to the depth_gen and less than the depth_res, a frequency bin to which the target emission frequency belongs may be determined by the formula Depth (j) =depth_gen+ (j-1) × (depth_res-depth_gen)/M, (j= … M), and the frequency bin corresponding to the frequency bin is taken as the value of the target emission frequency.
In the method for adjusting ultrasound imaging provided in the embodiment of the present application, a process of adjusting a real-time receiving demodulation parameter of a target ultrasound imaging device based on radio frequency signal data may specifically be: performing echo FFT (Fast Fourier Transform ) analysis on the radio frequency signal data to obtain an echo FFT analysis result; determining target receiving demodulation parameters based on echo FFT analysis results; the value of the target reception demodulation parameter is taken as the value of the real-time reception demodulation parameter.
In practical application, in the process of performing echo FFT analysis on radio frequency signal data to obtain an echo FFT analysis result, FFT analysis under different depths can be performed on radio frequency signal data received by each receiving line of a target ultrasound imaging device, and then the FFT analysis result with the same depth of each receiving line is averaged to obtain an echo FFT analysis result, for example, the echo FFT analysis result is obtained after summation/difference of transmitted echoes. In a specific application scene, when the target receiving demodulation parameters are determined based on the echo FFT analysis result, the target receiving demodulation parameters can be determined based on the echo FFT analysis result in a graphical mode; in addition, after the value of the target reception demodulation parameter is taken as the value of the real-time reception demodulation parameter, the filter coefficients of the respective filters of the target ultrasound imaging apparatus are generated, so that the respective filters of the target ultrasound imaging apparatus can be set directly according to the generated filter coefficients, and the target ultrasound imaging apparatus can obtain an optimal contrast agent echo signal by means of the filter coefficients.
In practical application, in the process of determining the target receiving demodulation parameters based on the echo FFT analysis result, the target frequency-demodulation value can be determined in the frequency values corresponding to the peak values in the FFT analysis result, specifically, the echo FFT analysis result can be displayed in a spectrogram form, the peak values and the frequency values corresponding to the peak values are determined in the spectrogram, and then the target frequency-demodulation value is determined in the frequency values corresponding to the peak values, for example, a certain number of frequency values corresponding to the peak values are used as the target frequency-demodulation value, and the mode of determining the target frequency-demodulation value can be determined according to actual needs; and determining target receiving demodulation parameters according to the target demodulation frequency value. Specifically, based on the nonlinear fundamental wave, the 1.5 th super harmonic and the second harmonic of the FFT analysis curve, the corresponding demodulation frequency point can be obtained, and the corresponding filter coefficient is generated. Since ultrasound contrast imaging requires maximum extraction of signals of these main frequencies of contrast agent reflection, the strongest signal distribution of contrast agent feedback can be obtained, the optimal frequencies are obtained for these signal distributions, and then the filter coefficients of each segment are generated according to the results of different depth analyses of these parameters, so that the optimal contrast agent echo signal can be obtained after signal demodulation and frequency compounding.
Referring to fig. 2, fig. 2 is a second flowchart of an ultrasound contrast imaging adjustment method according to an embodiment of the present application.
The method for adjusting ultrasonic contrast imaging provided by the embodiment of the application can comprise the following steps:
step S201: and acquiring the imaging frame rate and the real-time imaging depth of the target ultrasonic imaging equipment in the ultrasonic imaging process.
Step S202: the transmit timing of the target ultrasound contrast device is adjusted based on the imaging frame rate.
