Specific embodiment
A kind of aided diagnosis method and device based on shearing wave elastic image, can apply disclosed in the embodiment of the present application
On ultrasonic device, ultrasonic device is visualized for emitting shearing wave, and to the elastic information that shearing wave detects, visually
Elastic information is shearing wave elastic image.
Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of embodiments of the present application, instead of all the embodiments.It is based on
Embodiment in the application, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall in the protection scope of this application.
Fig. 1 is a kind of aided diagnosis method based on shearing wave elastic image disclosed in the embodiment of the present application, including following
Step:
S101: the shearing wave elastic image at diagnosis position is obtained.
Specifically, the probe that ultrasonic device can be used emits shearing wave to diagnosis position, and set according to ultrasound is reflexed to
Standby shearing wave is imaged, to obtain the shearing wave elastic image at diagnosis position.
In the present embodiment, diagnosis position includes but is not limited to: the different position of elasticity, example under normal condition and pathological condition
Such as liver.
S102: according to the shearing wave elastic image at diagnosis position, the elastic parameter at diagnosis position is calculated, object elastic is obtained
Parameter.
In the present embodiment, elastic parameter includes but is not limited to Young's modulus, is illustrated by taking Young's modulus as an example below.
According to the shearing wave elastic image at diagnosis position, the specific method of the Young's modulus at diagnosis position, Ke Yican are calculated
See the prior art, which is not described herein again.
S103: the state at diagnosis position and the default corresponding relationship of elastic parameter are obtained.
Because the elasticity at the different diagnosis position of state is different, elastic parameter is different.It is right by taking Young's modulus as an example
It should be related to diagnose the corresponding relationship of the state at position and Young's modulus.If table 1 is each state as diagnosis position liver
With the corresponding relationship of Young's modulus.
It is emphasized that number of actual measurements of the Young's modulus according to ultrasonic device in the present embodiment, in corresponding relationship
According to determination.Specifically, the ultrasonic device of measurement Young's modulus, the ultrasound for as collecting the shearing wave image at diagnosis position is set
It is standby.
Further, because ultrasonic device can acquire the shearing wave elastic image at diagnosis position, and according to shearing wave
The Young's modulus at elastic image measurement diagnosis position, so, the poplar at the diagnosis position that available ultrasonic device had measured
Family name's modulus (i.e. the Young's modulus at historical diagnostic position), and the true health status at historical diagnostic position is obtained, resettle history
The Young's modulus at position and the corresponding relationship of true health status are diagnosed, the state as disconnected position is corresponding with elastic parameter to close
System.
The process for more specifically obtaining corresponding relationship is introduced in following embodiment.
It should be noted that the acquisition of corresponding relationship, can process shown in Fig. 1 start before execute, in S103, only
Corresponding relationship need to be obtained from the memory module of ultrasonic device, therefore, the corresponding relationship of acquisition is considered as default correspondence
Relationship.
S104: according to corresponding relationship is preset, the corresponding state of object elastic parameter being calculated is determined.
For example, including that liver, mammary gland etc. diagnose the state at position and the corresponding relationship of Young's modulus in corresponding relationship.Its
In, (the Young's modulus section in table 1 is only to show to the corresponding relationship example of the different conditions of liver and Young's modulus as shown in table 1
Example, does not represent true Young's modulus):
Table 1
| Liver state | Young's modulus section |
| Normally | 【1-6】 |
| 1 grade of liver fibrosis | 【7-10】 |
| 2 grades of liver fibrosis | 【11-15】 |
| 3 grades of liver fibrosis | 【16-20】 |
| 4 grades of liver fibrosis | 【17-25】 |
| 5 grades of liver fibrosis | 【26-30】 |
Assuming that the value of the Young's modulus for the liver being calculated in S102 is 5, the table of comparisons 1 is fallen in section [1-6], because
This, it is normal that diagnosis, which prompts the state of corresponding liver,.
S105: generating and exports diagnosis prompt.
In the present embodiment, diagnosis prompt includes the corresponding state of object elastic parameter at diagnosis position, such as above-mentioned liver
State " normal ".
Optionally, in order to increase diagnosis position diagnostic state credibility, diagnosis prompt in can also include diagnostics division
Each state of position and the corresponding relationship of each elastic parameter.
It can be seen that in the present embodiment from process shown in FIG. 1, after the shearing wave elastic image for obtaining diagnosis position,
The elastic parameter at diagnosis position is calculated, and according to corresponding relationship and elastic parameter, determines the state at diagnosis position.Therefore, real
The purpose that may cause the disease of tissue elasticity variation using ultrasonic image diagnosis is showed, so unnecessary puncture can be reduced
Biopsy can be detected the lesion (such as liver fibrosis) that suspicious and previous ultrasound image is difficult to, to implement earlier
Remedy measures.
More importantly the corresponding relationship for auxiliary diagnosis, the actual measurement data according to ultrasonic device is determined, because
This, corresponding relationship is suitable for the shearing wave elastic image that ultrasonic device obtains, i.e., for any one ultrasonic device, corresponding relationship
Suitable for the ultrasonic device, thus it is possible to the ultrasound transmitting-receiving discrepant ultrasonic device of principle is avoided to share a set of corresponding relationship, into
And restriction of the ultrasonic device for auxiliary diagnosis is avoided, with the existing aided diagnosis technique based on shearing wave elastic image
It compares, method described in the present embodiment has universality.
Fig. 2 is the acquisition process of corresponding relationship described in Fig. 1, comprising the following steps:
S201: the true health status of the sample at the diagnosis position is obtained, and is obtained by ultrasonic device actual measurement
, sample corresponding elastic parameter under true health status.
The sample at diagnosis position refers to that ultrasonic device has collected shearing wave elastic image and according to shearing wave elasticity
Image determines the diagnosis position of Young's modulus.That is, the diagnosis position that will have been crossed after diagnosing, as sample.
Wherein, true health status and the above-mentioned state determined according to Young's modulus and corresponding relationship are (hereinafter referred to as pre-
Survey state) it is different, true health status can be the true strong of the more close diagnosis position using modes such as biopsies, determined
The state of health state.
Specifically, each sample can be obtained by way of receiving the biopsy results for each sample being manually entered
True health status.
For example, a ultrasonic device tested Young's modulus to 100 livers and this 100 livers have been made a definite diagnosis
(mode of making a definite diagnosis may include biopsy etc.), then using this 100 livers as the sample of liver.
Assuming that the true health status of a liver in sample is normal, the poplar for the liver that ultrasonic device measurement obtains
Family name's modulus is 5, then true health status " normal " and Young's modulus " 5 ", as one in corresponding relationship group corresponding relationship.
It should be noted that sample can be corresponded to by the unique identification of patient, such as name or social security card number etc.
Parameters (including predicted state, true health status, Young's modulus etc.) carry out result output.
S202: for any one true health status, corresponding each elastic parameter under the true health status is calculated
Accounting.
Wherein, accounting refers to, the quantity of an elastic parameter corresponding sample under the true health status, true at this
In the quantity of all samples under health status, shared ratio.
For example: for 3 livers, ultrasonic device divides according to the Young's modulus that its shearing wave elastic image is calculated
Not Wei 1,5 and 5, also, the biopsy results of this three livers be it is normal, i.e. the true health status of this three livers is positive
Often, in normal state, the accounting of Young's modulus 1 is 1 (quantity of the corresponding sample of Young's modulus 1)/3 (normal liver samples
This total quantity) ≈ 33%, the accounting of Young's modulus 5 is 2 (quantity of the corresponding sample of Young's modulus 5)/3 (normal livers
The total quantity of sample) ≈ 67%.
As it can be seen that accounting is also considered as the probability of elastic parameter appearance in the case where sample is enough.
S203: for any one true health status, by elastic parameter sequence corresponding under the true health status,
The sum of accounting be greater than preset threshold top n elastic parameter, as the diagnosis position under the true health status corresponding bullet
Property parameter.
Wherein, the corresponding elastic parameter sequence of any one true health status are as follows: all under the true health status
The sequence that elastic parameter is arranged according to the sequence of accounting from big to small.
It should be noted that if the accounting of first elastic parameter in the sequence is to be greater than preset threshold, first
A elastic parameter is otherwise the diagnosis position corresponding elastic parameter under the true health status joins the latter elasticity
Several accountings is added with the accounting of first elastic parameter, if sum of the two is greater than preset threshold, the first two elastic parameter
The corresponding elastic parameter ... ... of the true health status at the as diagnosis position and so on.
For example: table 2 is the Young's modulus and accounting that 20 normal livers are obtained by ultrasonic device measurement.
Table 2
From Table 2, it can be seen that the Young's modulus of 20 normal livers is distributed in section [0,6], each Young's modulus exists
Accounting in the total sample of normal liver (i.e. 20) is distributed as shown in the probability in table 2, for example, Young's modulus 0 is in 20 samples
This accounting is 2%, that is, having 20*2%=4 normal liver using the Young's modulus that step S201-S204 is obtained is 0.
In the manner described above, it determines that maximum accounting is 60% from table 2, is less than threshold value 80%, then continues to look for second largest account for
Than for 10%, 60% and 10% and be 70%, be still not more than threshold value 80%, continuing to look for the third-largest accounting is 10%, 60%,
10% and 10% and be 80%, be still not more than threshold value 80%, then continuing to look for the fourth-largest accounting is 8%, 60%, 10%, 10%
With 8% and be 88%, be greater than threshold value 80%, then 3 and of Young's modulus that accounting is 60% Young's modulus 5, accounting are 10%
4 and accounting be 8% Young's modulus 6, be the corresponding Young's modulus of normal condition of liver to get to the normal of liver
The corresponding Young's modulus section of state is [3,6].
So far, the state at the diagnosis position for auxiliary diagnosis and the corresponding relationship of Young's modulus are obtained.It needs to illustrate
It is that above to be illustrated by taking the normal condition of liver as an example, Young's modulus corresponding for other true health status uses
Process identical with normal condition obtains, and for other diagnosis positions, is obtained using process identical with liver, no longer superfluous here
It states.
It should be noted that can be used to improve the accuracy of corresponding relationship and be placed on the same of different location
The data of the sample of the actual measurement of the ultrasonic device of type, determine corresponding relationship.
Specifically, in step s 201, obtaining the true health status of the sample at diagnosis position, and by difference is arranged in
The sample of the same type of ultrasonic device actual measurement of application site, the corresponding elastic parameter under true health status,
And in the next steps, the elastic parameter obtained with the ultrasonic device actual measurement of different location is executes object.
In practice, the ultrasonic device of same producer's production, ultrasonic transmitting-receiving principle usually identical (the i.e. class of ultrasonic device
Type is identical), therefore, the diagnosis position that the ultrasonic device actual measurement which is placed on different location is crossed, can as sample
With the sample that referred to as multicenter acquires, by data (Young's modulus and true health status including actual measurement) conduct of sample
The determination basis of corresponding relationship can obtain wider data, so that corresponding relationship has higher accuracy.It can will be same
The sample for the actual measurement that the multiple ultrasonic devices for being placed on different location (such as multiple hospitals) of one producer's production are collected
Data determine corresponding relationship, referred to as multicenter result.
Further, in order to improve the accuracy of corresponding relationship, the measurement data of new samples can also be used, for
The corresponding relationship that S201-S203 is obtained is modified, and detailed process is as follows:
S204: the elasticity for obtaining the ownership health status of the new samples at diagnosis position and being obtained by ultrasonic device actual measurement
Parameter.
Wherein, the ownership health status of new samples be new samples true health status, in order to it is true in S201-S203
Real health status distinguishes, referred to herein as " ownership health status ".
Wherein, new samples refer to, the shearing wave elastic graph at ultrasonic device new collected diagnosis position in practical applications
Picture and the Young's modulus determined according to shearing wave elastic image.
S205: the ownership health by original sample under the ownership health status of new samples and new samples, as new samples
Sample under state.
Wherein, original sample under the ownership health status of new samples, as under the ownership health status of new samples
Used sample in S201-S203.
For example, during determining corresponding relationship in S201-S203, being used normal to 20 by taking normal liver as an example
Liver, then original sample is 20, it is assumed that has 5 normal livers in new samples, then any one in this 5 is new sample
This, new samples is added in the sample under the normal condition of liver.
S206: the accounting of corresponding each elastic parameter under the ownership health status of new samples is calculated.
Wherein, elastic parameter is obtained by ultrasonic device actual measurement.
The calculation of the accounting of elastic parameter as previously mentioned, any one elastic parameter accounting are as follows: the elastic parameter
The quantity of corresponding sample under the true health status (i.e. the ownership health status of new samples), under the true health status
All samples total quantity in shared ratio.
S207: by the elastic parameter sequence under the ownership health status of new samples, the sum of accounting is greater than preset threshold
Top n elastic parameter, as diagnosis position corresponding amendment elastic parameter under the ownership health status of new samples.
Wherein, the elastic parameter sequence under the ownership health status of new samples is the bullet of the sample under the true health status
Property parameter, the sequence arranged according to the sequence of accounting from big to small.
It should be noted that above-mentioned S204-S207 is the makeover process for any one new samples, in practice, according to
After S204-S207 is completed for the makeover process of whole new samples, that is, complete the amendment for corresponding relationship.
Assuming that table 1 show initial corresponding relationship, table 2 show a part (normal condition of revised corresponding relationship
The corresponding relationship of liver), compared with the corresponding Young's modulus section of normal condition of the liver shown in the table 1 of table 2, reduce liver
The corresponding Young's modulus section of normal condition.Realize the amendment for initial corresponding relationship.
It should be noted that a kind of situation to reduce the scope only under above-mentioned example, it is also possible to, after amendment, Young
The interval range of modulus is constant.
Optionally, the same type of ultrasonic device actual measurement mistake that different location is arranged in also can be used in new samples
Diagnosis position sample, that is, correcting the new samples that use is the sample that multicenter is collected into, to further increase corresponding relationship
Accuracy.
It can be seen that the actual measurement data that same type of ultrasonic device can be used from process shown in Fig. 2, into one
Step is modified initial corresponding relationship, therefore, can carry out after obtaining initial object relationship according to initial object relationship
Using shearing wave elastic image auxiliary diagnosis, also, collects the new data that generates in support decision process (including ultrasonic device is surveyed
The Young's modulus and corresponding true health status measured), the new data newly collected is recycled, initial corresponding relationship is carried out
Amendment.
That is, on the basis of using shearing wave elastic image auxiliary diagnosis, additionally it is possible to which the case according to diagnosis is repaired
Positive diagnosis basis so that diagnosis basis is constantly corrected, and realizes the increasing with diagnosed case to add up with sample
Add, the effect that the accuracy of auxiliary diagnosis is also promoted therewith.
It should be noted that in Fig. 2, the elastic parameter of sample or new samples can obtain automatically from ultrasonic device, may be used also
With, the elastic parameter at the diagnosis position being manually entered is received, for new samples data for the amendment of initial corresponding relationship, this
The correcting mode of the elastic parameter at the diagnosis position that kind utilization is manually entered, is properly termed as manual correction, and obtains auxiliary automatically
The correcting mode of elastic parameter obtained in diagnosis process is properly termed as correcting automatically.
Fig. 3 is a kind of auxiliary diagnostic equipment based on shearing wave elastogram disclosed in the embodiment of the present application, comprising: image
