For the ease of understanding technical solution provided by the present application, first the research background of technical scheme is carried out below
Simple declaration.
Traditional two-dimensional ultrasonic imaging system provides the two dimensional image of a certain diseased region section of human body, and doctor is necessary
Two-dimensional images are synthesized in the brain according to the experience of oneself to understand its 3 D anatomy structure, this makes in heart
The diagnosis of sick and fetus congenital anomaly etc. has certain limitation.Compared with traditional two-dimensional ultrasonic imaging, three-dimensional is super
Acoustic imaging operation and image taking speed are fast, can be accurately measured to structural parameters, the clear solid shape for showing suspect structure, clearly
Clear lesions showed internal structure and content characteristic, the spatial relation inside clear lesions showed, after capable of carrying out routine examination
Reprocessing analysis etc., be widely applied in a series of clinical applications such as early stage fetal disease screening.But current three-D ultrasonic
Image quality is not very high, there is gap between 3-D view and true picture, this is because in current 3-D supersonic imaging,
The conventional gain compensation method of use is mended to being all made of identical gain applied to each two-dimensional ultrasonic image of three-dimensional modeling
Coefficient is repaid to compensate, and this gain compensating method has ignored differential declines situation of the ultrasonic wave on different imaging sections,
And then affect the picture quality of 3-D supersonic imaging.
Based on this, present applicant proposes a kind of 3-D supersonic imaging methods, by different during 3-D supersonic imaging
By imaging section compensated using different gain compensation parameters, promote the three-dimensional ultrasound pattern quality of imaged object,
This method is introduced below.
Referring to Fig. 2, it illustrates a kind of flow chart of 3-D supersonic imaging method provided by the embodiments of the present application, such as Fig. 2

Structure and content characteristic etc. contribute to the subsequent processing after carrying out routine examination to analyze, have been widely applied to early stage fetus at present
In a series of clinical applications such as disorder in screening.
But in current clinical application, three-dimension ultrasonic imaging system using ultrasonic diagnosis scan human body when, due to
Ultrasonic wave is during tissue internal communication, it may appear that the case where energy is gradually decayed as depth increases, thus it is deep
The echo-signal for spending histoorgan is more much smaller than the echo-signal of shallow histoorgan, in order to obtain good imaging effect, just
Rational gain compensation amplification measure must be taken, the weak signal of diagnostic value is shown with enhancing, is realized preferable three-dimensional super
Acoustic imaging effect.
Section is imaged using different to different present applicant proposes during 3-D supersonic imaging based on this
The method that gain compensation parameters compensate, to promote the three-dimensional ultrasound pattern quality of imaged object.
In the embodiment of the present application, in order to obtain the better three-dimensional ultrasound pattern of imaging effect, it is necessary first to determine by
Each as object is imaged section.
Wherein, imaged object refers in clinical medical, and clinician is needed to be obtained using three-dimension ultrasonic imaging system
To clearly stereo-picture, to carry out the human testing position of subsequent processing analysis, such as to the progress of pregnant woman foetus
When 3-D supersonic imaging, pregnant woman foetus is exactly imaged object.And correspondingly, each referred to generating quilt by imaging section
Each section of the two-dimensional display image of imaging object.And each imaging section is 3-D imaging system in moment from different angles
Degree display is conducive to show the anatomical structure of imaged object and its section ultrasonogram of echo characteristics.
Three-dimension ultrasonic imaging system can be cut after determining each section by imaging of imaged object according to by imaging
Face putting in order in the imaged object executes step 202 and 203 to each by imaging section successively, or right simultaneously
It is each that step 202 and 203 is executed by imaging plane.
Step 202：After by imaging section by ultrasonic irradiation, the two-dimensional ultrasonic image for being imaged section is generated, as
Initial ultrasound image.
As shown in figure 3, in practical applications, three-dimension ultrasonic imaging system can utilize energy converter (i.e. ultrasonic probe) to shine
Penetrate imaged object, when imaged object it is each by imaging section by ultrasonic irradiation after, can generate and each be cut by imaging
The corresponding two-dimensional ultrasonic image in face, as initial ultrasound image.Also, initial ultrasound image can be used as a 3 d ultrasonography
The imaging basis of picture, on the basis of this two dimensional image, further carries out subsequent operation, to realize three-dimensional ultrasound pattern to it
Imaging.
Step 203：Determine the gain compensation parameters sequence of initial ultrasound image, wherein different initial ultrasound images correspond to
Different gain compensation parameters sequences.
In practical applications, by step 202, three-dimension ultrasonic imaging system can obtain imaged object it is each by
As the corresponding two-dimensional ultrasonic image in section, i.e. initial ultrasound image.But for energy converter transmitting ultrasonic wave for, it is each by
As depth position that section is located at imaged object is different, and then ultrasonic wave is irradiated to each by imaging section
During, can gradually it decay with being increased by depth of the imaging section in imaged object, it is therefore, each to be cut by imaging
Face is different by the attenuation after the practical irradiation of ultrasonic wave, so the initial ultrasound image generated is also different, as a result,
In order to make more accurate gain compensation by the corresponding initial ultrasound image in imaging section to each, it is necessary at the beginning of different
Beginning ultrasonoscopy determines the corresponding gain compensation parameters sequence of different initial ultrasound images.
In the application in some possible realization methods, step 203 can specifically include：
Step A：Determine the corresponding ultrasound echo signal intensity of each pixel in the initial ultrasound image；
Step B：According to the ultrasound echo signal intensity, the corresponding gain compensation parameters of the pixel are determined.
In this realization method, each by imaging section of imaged object can be generated by step 201 and step 202

The corresponding ultrasound echo signal intensity of vegetarian refreshments, specific formula for calculation are as follows：
I(depthij)=I0exp(-α*depthij) (1)
Wherein, depthijIndicate j-th of pixel in i-th of initial ultrasound image it is corresponding by imaging point apart from transducing
The distance of device, it is described by imaging point be i-th of initial ultrasound image it is corresponding by imaging section in point, I (depthij) indicate
The corresponding ultrasound echo signal intensity of j-th of pixel in i-th of initial ultrasound image, I0It indicates infinitely close apart from energy converter
The echo signal intensity of point, α indicate that attenuation coefficient, value depend on the tissue material of imaged object.
In turn, it can determine that each pixel is ultrasonic time corresponding in different depth initial ultrasound image according to formula (1)
Wave signal strength I (depthij), further determine that out that the corresponding gain of each pixel is mended in different depth initial ultrasound image
Repay parameter.The specific of the corresponding gain compensation parameters of each pixel in the initial ultrasound image of different depth was determined below
Journey illustrates：
Natural logrithm is asked to can be obtained formula (2) simultaneously firstly, for formula (1) both sides as follows：
ln(I(depthij))=ln (I0exp(-α*depthij)) (2)
=lnI0-α*depthij
Wherein, because of I0For constant, so lnI0It is also a constant, ln (I (depthij)) indicate i-th of initial ultrasound
The natural logrithm of the corresponding ultrasonic echo intensity of j-th of pixel in image, value is with depth linear change.
But since the pixel number of progress gain compensation is denary logarithm compression according to the compress mode of use, without
It is the natural logrithm compression used, so, ask logarithm that formula (3) can be obtained the bottom of for 10 simultaneously on formula (1) both sides as follows：
log10(I(depthij))=- (alog10e)α*depthij (3)
Wherein, a is for synthesizing constant determined by the functional unit of ultrasonic wave, and specific formula for calculation is as follows：
Wherein, CH indicates that the coboundary of compression function, CL indicate the lower boundary of compression function.
As shown in figure 4, it illustrates the corresponding broken line schematic diagrames of compression function.
The corresponding gain compensation ginseng of each pixel in the initial ultrasound image of different depth can be obtained in conjunction with formula (1)
Number is：
Wherein, Gain (depthij) indicate that the corresponding gain compensation of j-th of pixel in i-th of initial ultrasound image is joined
Number.
Further, formula (5) can be converted to a decibel intermediate scheme, i.e., it is as follows：
Gain(depthij)=20log10(exp(α*depthij))-20log10(I0) (6)
Wherein, Gain (depthij) indicate that the corresponding gain compensation of j-th of pixel in i-th of initial ultrasound image is joined
Several decibel representations.
As it can be seen that by above-mentioned calculation, the corresponding increasing of each pixel in initial ultrasound image can be calculated
Beneficial compensating parameter.
Further, since the gain compensation parameters being currently calculated may be inaccurate, when passing through above-mentioned side
After the corresponding gain compensation parameters of each pixel in initial ultrasound image are calculated in formula, parameters revision can also be carried out.
In a kind of optional embodiment, can also include after above-mentioned steps B：
Step C：Determine the corrected parameter of the corresponding gain compensation parameters of the pixel；
Step D：Using the corrected parameter, the corresponding gain compensation parameters of the pixel are modified.
In the optional embodiment, the corresponding increasing of j-th of pixel in determining i-th of initial ultrasound image
Beneficial compensating parameter Gain (depthij) after, it may further determine that out j-th of pixel pair in i-th of initial ultrasound image
The corrected parameter for the gain compensation parameters answered.
In some possible realization methods, step C can specifically include：According to gradation of image information, the picture is determined
The corrected parameter of the corresponding gain compensation parameters of vegetarian refreshments, wherein described image half-tone information includes the image ash of the pixel
Angle value.
In this realization method, in order to improve the standard of the corresponding gain compensation parameters of each pixel in initial ultrasound image

Average gray value, that is, step C can specifically include, according to the average gray value of the initial ultrasound image and the pixel
The gray value of image of point, determines the corrected parameter of the corresponding gain compensation parameters of the pixel.
In this realization method, the gradation of image information of initial ultrasound image can be utilized, i.e., it is each in initial ultrasound image
The average gray value of a pixel corresponding gray value of image and initial ultrasound image, determines each picture in initial ultrasound image
The corrected parameter of the corresponding gain compensation parameters of vegetarian refreshments, specific formula for calculation are as follows：
Wherein, μ (depthij) indicate i-th of initial ultrasound image in the corresponding gain compensation parameters of j-th of pixel
Corrected parameter, Gray (depthij) indicate i-th of initial ultrasound image in the corresponding gray value of image of j-th of pixel,
Gray (mean) indicates that the average gray value of i-th of initial ultrasound image, β indicate correction-compensation weight, determined by empirical value, than
Such as β=2.
In determining initial ultrasound image after the corrected parameter of the corresponding gain compensation parameters of each pixel, you can right
The corresponding gain compensation parameters of each pixel are modified, that is to say, that the μ that formula (7) can be utilized to be calculated
(depthij), the Gain (depth that formula (6) is calculatedij) be modified, specific correction formula is as follows：
Gain(depthij)1=20log10(exp(α*depthij))-20log10(I0)+μ(depthij) (8)
Wherein, Gain (depthij)1Indicate that j-th of pixel in revised i-th of initial ultrasound image is corresponding
Gain compensation parameters.
In calculating initial ultrasound image after the corresponding gain compensation parameters of each pixel, the present embodiment increases these
Beneficial compensating parameter is known as the gain compensation parameters sequence of initial ultrasound image.It is calculated by above-mentioned analysis it is found that different initial super
