Step S101：Determine preset object elastic measurement method.
In specific implementation, a kind of preferred elasticity measurement mode, example can be arranged in user in Ultrasonic elasticity measuring device It such as, can be according to lesion in the case of the detection for the lesion for being mainly used for a certain type in the Ultrasonic elasticity measuring device Specific features select the elasticity measurement mode for being best suited for the lesion as limited elasticity measurement mode, i.e. object elastic measures Mode.
For example, in a specific embodiment, it is most of to use in the inspection that current ultrasonic elasticity measuring device is carried out The inspection at family will be directly based in the case where can be achieved the goal using the vibrating elastic measurement method based on external force vibration The vibrating elastic measurement method of external force vibration is as preferred elasticity measurement mode, i.e. object elastic measurement method.
In the present embodiment, elasticity measurement mode can be vibrating elastic measurement method based on external force vibration, be based on sound Width penetrates the shearing wave measurement method of power, strain elasticity measurement mode.
Specifically, the vibrating elastic measurement method based on external force vibration generates shearing wave by external force vibration is passed to tissue, Then it generates the propagation of shearing wave by portion within the organization and detects the method for its propagation parameter (such as spread speed) and reflect Nonhomogeneous hardness between tissue.For isotropic elastic fibrous tissue, the spread speed C of shearing wavesBetween tissue elasticity modulus E There are following relationships：Young's modulus(wherein, ρ is tissue density).That is, shear wave velocity and springform There are one-to-one relationships for amount.
Based on the shearing wave measurement method of acoustic emanation power by ultrasonic acoustic radiation force within the organization portion generate shearing wave biography It broadcasts, the propagation of shearing wave is then generated by portion within the organization and detects the method for its propagation parameter (such as spread speed) come anti- Reflect the nonhomogeneous hardness between tissue.For isotropic elastic fibrous tissue, the spread speed C of shearing wavesWith tissue elasticity modulus E it Between there are following relationships：Young's modulus(wherein, ρ is tissue density).That is, shear wave velocity and elasticity There are one-to-one relationships for modulus.
Strain elasticity measurement mode or conventional Ultrasound elasticity measurement mode, basic principle are：It will the slight compressing of probe Destination organization or by processes such as breathing, the vascular pulsations of human body itself to organizing the formation of certain pressure, before obtaining compression, Two frame ultrasound echo signal afterwards when tissue is compressed, will generate a strain along compression direction, if organization internal in tissue Young's modulus is unevenly distributed, the Strain Distribution in tissue also will difference, then detect tissue by certain methods Strain information, then by dependent variable, strain rate etc. calculated with the relevant parameter of tissue elasticity and at, to indirectly reflection apply Elastic difference in intermediate pressure section between different tissues.Specifically, according to Hooke's law, for isotropic elastomer, stress σ =strain stress × Young's modulus E, i.e. E=σ/ε.Wherein, Young's modulus E is got over the relevant parameter of tissue hardness, Young's modulus Height shows that tissue hardness is bigger.
It should be noted that in the present embodiment, elasticity measurement mode is not limited to the above-mentioned elasticity measurement mode enumerated, It can also be other elasticity measurement modes based on ultrasonic elastograph imaging.
In the present embodiment, preset object elastic measurement method can be not only pre-set specified elasticity measurement Mode can also be that user is needing the when of being detected using Ultrasonic elasticity measuring device to set, for example, starting to measure it Before set.
For example, in a specific embodiment, before being detected using Ultrasonic elasticity measuring device, on display circle Alternative elasticity measurement mode is shown on face, selects an elasticity to survey in multiple elasticity measurement modes of displaying by user Amount mode is measured as object elastic measurement method.
In another specific embodiment, before being detected using Ultrasonic elasticity measuring device, user is not straight The object elastic measurement method being detected is selected in selecting, but by inputting keyword corresponding with the detection currently carried out, by Ultrasonic elasticity measuring device determines object elastic measurement method according to keyword input by user.
Specifically, the above-mentioned preset object elastic measurement method of determination includes：At least one character string for receiving input is made For keyword；In preset at least one elasticity measurement mode, according to preset elasticity measurement mode and keyword Matching relationship determines elasticity measurement mode corresponding with the keyword as object elastic measurement method.
Character string input by user can be doctor identification, test serum position, cause of disease etc., and the character string inputted can To be more than one.When the character string of input is " liver, cancer ", " liver, cancer " is used as keyword.
Different keywords has corresponded to different elasticity measurement modes, therefore, keyword determination after, you can determine with The corresponding elasticity measurement mode of the keyword.For example, in the case where keyword is " liver, cancer ", determining elasticity measurement Mode is the shearing wave measurement method based on acoustic emanation power.
In another embodiment, keyword can be not only one or more character string, can also be the disease of user Number of cases determines keyword automatically according to case data or history case data according to either history case data or determines target Elasticity measurement mode.
It should be noted that in the present embodiment, the determination of preset object elastic measurement method can also be its other party Formula, such as according to the historical data of Ultrasonic elasticity measuring device, determine the highest elasticity measurement mode of frequency of use；Alternatively, root Object elastic measurement method is determined according to historical data and the keyword being currently received.
Step S102：Measurement parameter corresponding with the object elastic measurement method is obtained, according to the measurement parameter pair Ultrasonic probe is configured.
Different elasticity measurement modes has corresponded to different concrete operations, also, the radiation pattern of corresponding ultrasonic wave It differs, that is to say, that different elasticity measurement modes has corresponded to the different emission parameter of ultrasonic probe.In the present embodiment, After the object elastic measurement method being detected determines, you can obtain preset corresponding with the object elastic measurement method Measurement parameter (for example, emission parameter of ultrasonic probe), and the emission parameter of ultrasonic probe is set according to the measurement parameter It sets, so that the relevant parameter and object elastic measurement method of the ultrasonic wave of ultrasonic probe transmitting are matched.
In a specific embodiment, above-mentioned acquisition measurement parameter corresponding with the object elastic measurement method, root According to the measurement parameter to ultrasonic probe be configured including：Obtain corresponding with object elastic measurement method wavelength or Frequency；The emission parameter of ultrasonic probe is configured according to the wavelength of the acquisition or frequency, so as to control the ultrasound The pulse train emitted of popping one's head in is corresponding with the wavelength of the acquisition or frequency.
That is, different elasticity measurement modes has corresponded to the ultrasonic wave of different frequency or wavelength, and difference is corresponded to Radiation pattern, therefore, object elastic measurement method determination after, you can obtain it is corresponding with the object elastic measurement method Frequency or wavelength, and the emission parameters such as radiation pattern corresponding with the object elastic measurement method are obtained, then ultrasound is visited The emission parameter of head is configured so that ultrasonic probe transmission is ultrasonic wave with the wavelength of acquisition or frequency be it is corresponding, And it is corresponding with the radiation pattern of acquisition.
Step S103：By the ultrasonic probe to test serum transmitting and the matched ultrasonic wave of the measurement parameter, connect Receive the echo signal data returned.
After the emission parameter to ultrasonic probe is configured, you can using Ultrasonic elasticity measuring device to test serum It is detected.Specifically, control ultrasonic probe using pulse train occurs ultrasonic wave, the pulse train and target to test serum The corresponding measurement parameter of elasticity measurement mode is matched.
It should be noted that in the present embodiment, the ultrasonic wave sent from ultrasonic probe to test serum is shearing wave, i.e., The direction of propagation of ultrasonic wave is vertical with the direction of vibration of the particle of test serum.
After emitting shearing wave to test serum by ultrasonic probe, shearing wave can be passed in test serum It broadcasts.In the present embodiment, ultrasonic probe can not only emit signal, can also receive signal, that is, receive test serum and be reflected back Signal data, i.e. ultrasonic probe receives the echo signal data that is reflected back of test serum.
In the present embodiment, the signal of ultrasonic probe transmitting is standard signal, and the echo letter that ultrasonic probe receives Number is the signal data that some position by test serum is reflected back.Because the elasticity at each position of test serum, Or hardness etc. is different because the echo signal data being reflected back as the elasticity at each position of test serum or There is difference in the inconsistent of the parameters such as person's hardness, to reflect the related data of test serum.
Step S104：It determines reference parameter corresponding with the object elastic measurement method, judges the echo-signal number According to whether matching with the reference parameter；If it is not, thening follow the steps S105：In preset at least one elasticity measurement mode really The elasticity measurement mode for determining to select executes step S102 as object elastic measurement method：It obtains and is surveyed with the object elastic The corresponding measurement parameter of amount mode, is configured ultrasonic probe according to the measurement parameter；If so, thening follow the steps S106： Elasticity measurement data corresponding with the test serum are generated according to the echo signal data and are exported.
In the present embodiment, the echo signal data that ultrasonic probe receives is to be detected by Ultrasonic elasticity measuring device The data arrived.In the present embodiment, final output echo signal data not measured as Ultrasonic elasticity, it is also necessary to Corresponding elasticity measurement data are generated according to echo signal data, and using finally obtained elasticity measurement data as detection data Output, for example, exporting the elasticity measurement data in the form of elastic image.
In the present embodiment, it is not to be given birth in all cases by echo signal data or according to echo signal data At elasticity measurement data exported as the final output that Ultrasonic elasticity measures and terminate entire Ultrasonic elasticity and measured Process, it is also necessary to the data detected are verified, that is, judge whether current Ultrasonic elasticity measurement succeeds, if measured Failure, then remeasured.
That is, for the echo signal data obtained by object elastic measurement method in step S103, it is also necessary to Judge whether the echo signal data meets quality requirement corresponding with object elastic measurement method, only in echo signal data In the case of meeting quality requirement, just think that the echo signal data is valid data, be just used as measurement result, otherwise, is returning In the case that wave signal data is unsatisfactory for quality requirement, it is believed that the echo signal data is invalid data, needs to re-start survey Amount.
In the present embodiment, for different elasticity measurement modes, corresponding echo signal data whether with the elasticity The deterministic process of the corresponding reference parameter of measurement method (can be signal quality parameter or other reference parameters) is also different.This The reference parameter mentioned in text is whether to meet the parameter value of elasticity measurement requirement for weighing echo data, for example, for weighing Measure the signal quality parameter of echo-signal, elastic qualities parameter that quality is measured for weighing shear wave velocity in echo-signal, For weighing the elastic qualities parameter etc. for organizing strain measurement quality in echo-signal.Different elasticity measurement modes correspond to not Same reference parameter.A kind of elastic qualities parameter is provided in following embodiment as the judgment mode with reference to parameter.Have at one In the embodiment of body, reference parameter can be understood as：It is strained in shearing propagation path or tissue according in test serum On at least two time points the elastic qualities parameter that obtains of change in location, and be used to carry out to judge elastic qualities ginseng when comparing Number can take some threshold value or some quantitative range.
Specifically, being shaking based on external force vibration in the object elastic measurement method in a specific embodiment In the case of dynamic elasticity measurement method, it is described judge the echo signal data whether matched with the reference parameter including：Root According to the echo signal data ultrasonic wave was determined on the propagation path in the test serum at least two time points Location information is dependent variable by independent variable, location information of time point, is carried out to the location information at least two time point Linear fit calculates the quadratic sum of residual error corresponding with the linear fit as fit quality parameter；Judge the fitting matter Measure whether parameter is less than fit quality parameter threshold, the fit quality parameter threshold is the described and vibration based on external force vibration The corresponding reference parameter of elasticity measurement mode；The case where the fit quality parameter is less than the fit quality parameter threshold Under, determine that the echo signal data is matched with the reference parameter；It is greater than or equal in the fit quality parameter described quasi- In the case of closing quality parameter thresholds, determine that the echo signal data is mismatched with the reference parameter.
In the present embodiment, in the vibrating elastic measurement method based on external force vibration, shearing wave is in incoming test serum Later, the signal returned according to test serum is cut when can determine shearing wave in the path of incoming test serum at each moment Cut the location information that wave travels to.
In the present embodiment, it can determine that shearing wave is more on the propagation path in test serum according to echo signal data The location information at a time point, it should be noted that in the present embodiment, the location information at determining time point at least 2, And when the quantity at time point is larger, the accuracy of the judgement of the signal quality parameter obtained is more acurrate.
It is dependent variable by independent variable, location information of time point, the location information at each two time points is carried out linear Fitting, determines the expression formula of linear fit, then, calculates the fit quality parameter of linear fit.In a specific embodiment In, the fit quality parameter of linear fit can be determined by calculating the error of fitting of linear fit, for example, calculating each The quadratic sum of difference between the match value at a time point location information corresponding with the time point is used as the quasi- of linear fit Close mass parameter.
For example, t1,t2,…,tnFor time point, corresponding location information is S1,S2,…,Sn, carry out what linear fit obtained Expression formula is S '=At+B, and fit quality parameter is
Then in the case where fit quality parameter is less than preset fit quality parameter threshold, the echo-signal is determined Data are matched with the reference parameter；The case where the fit quality parameter is greater than or equal to the fit quality parameter threshold Under, determine that the echo signal data is mismatched with the reference parameter.
For example, as shown in Fig. 2, be presented in Fig. 2 schematic diagram of the shearing wave in communication process, can be determined from figure The location information of different time points characteristic point (point shown in Fig. 2) then calculates the spread speed of shearing wave or average biography Broadcast speed.In general, spread speed is uniform, if larger fluctuation occurs in spread speed, measurement result may be by The influence of other factors, the error of fitting so as to cause the linear fit obtained according to time point and location information is larger, to Echo signal data is judged as to mismatch with reference parameter.
It is that the shearing wave based on acoustic emanation power is surveyed in the object elastic measurement method in another specific embodiment In the case of amount mode, it is described judge the echo signal data whether matched with the reference parameter including：Obtain described return The waveform feature data of wave signal data；Judge the waveform feature data whether with it is preset with described based on acoustic emanation power The corresponding reference parameter of shearing wave measurement method is matched；In the waveform feature data acoustic emanation is based on described with preset In the case of the corresponding reference parameter of shearing wave measurement method of power is matched, the echo signal data and the reference are determined Parameter matches；The waveform feature data and it is preset with described based on the corresponding ginseng of the shearing wave measurement method of acoustic emanation power Examine parameter it is unmatched in the case of, determine that the echo signal data and the reference parameter mismatch.
Because the shearing wave measurement method based on acoustic emanation power is easy to be interfered by noise, because can be from echo-signal The noise of data judges whether corresponding measurement data meets the requirements.
Specifically, in one embodiment, obtaining the corresponding waveform feature data of signal data in echo signal data, so Judge afterwards waveform feature data whether and it is preset with it is described based on the shearing wave measurement method of acoustic emanation power it is corresponding with reference to join Number is matched, for example, in the case of waveform feature data morphologic criteria, not lofty saltus step, determine wave character with Reference parameter is matched, conversely, the corresponding curve burr of waveform feature data is more, there are lofty saltus step, shearing wave amplitudes Spend low, signal-to-noise ratio it is excessively high in the case of, it is unmatched to determine that wave character belongs to reference parameter.
It is shearing wave morphologic criteria shown in Fig. 3, not lofty for example, in shearing wave form schematic diagram as shown in Figure 3 Saltus step, therefore be considered as being matched with reference parameter.In another embodiment, shearing wave as shown in Figure 4, curve burr It is more, there are lofty saltus steps, therefore be considered unmatched with reference parameter.
