Detailed description of the invention
Below in conjunction with specific embodiment, technical solution of the present invention is further illustrated.
As it is shown in figure 1, the specific embodiment of the present invention is: provide a kind of multi-modal microwave breast formation method, comprise the steps:
Microwave Scanning: microwave signal generating unit generation microwave broadband pulse signal and microwave single-frequency coherent signal, microwave signal antenna element is in a spiral manner around breast area motion scan to be measured, microwave signal antenna element launches microwave broadband pulse signal and microwave single-frequency coherent signal, and microwave signal antenna element receives microwave broadband pulse echo signal and microwave single-frequency echo-signal；
Specific implementation process is as follows: microwave generating unit passes through microwave signal antenna element to breast area generation microwave broadband pulse signal to be measured, microwave broadband pulse signal irradiates the focal area in imaging region, produce scattering on surface, focal area, receive the microwave broadband pulse echo signal from focus surface scattering with the scanning of several microwave signal antenna elements.Microwave generating unit is by microwave signal antenna element to breast area generation microwave single-frequency coherent signal to be measured, and the scanning of microwave signal antenna element receives and records the microwave single-frequency echo-signal of position.Microwave signal antenna element alternately realizes signal and launches and receive；Or microwave transmitting antenna and microwave antenna are array arrangement, carry out launching microwave signal and receiving microwave echoes signal simultaneously, microwave signal generating unit is multiple signal generator, provides microwave broadband pulse signal and microwave single-frequency coherent signal respectively for system simultaneously.In transmitting and reception process, microwave signal antenna element is in a spiral manner around breast area motion scan to be measured.
Imaging respectively: generate radar detection image according to microwave broadband pulse echo signal, according to microwave single-frequency echo signal form tomoscan image.
Specific implementation process is as follows: microwave radar image-forming principle utilizes theory of SAR, using a miniature antenna as single radiating element, the continuous motion scan in direction along a straight line, movement select some positions launch signal, receiving the corresponding echo-signal launching position, storage receives amplitude and the phase place of signal.Received the time of microwave scattering signal by microwave signal antenna element record, time delay can be calculated, and the distance of microwave transmitting antenna and focus is fixed, therefore micro-transmitting antenna distance to focus can be obtained, thus carrying out accurate imaging.Microwave wave circuits and systems method is similar to computed tomography (CT), it it is a kind of THE INVERSE ELECTROMAGNETIC SCATTERING method, by scattering object external observation to electromagnetic field carry out the electromagnetic signature parameter distribution in inversion imaging region, thus judging the information such as the position of scattering object target, shape and size distribution.The microwave single-frequency echo-signal that will receive, according to electromagnetic signature parameter distribution and the position of scattering object target, shape and size distributed intelligence generation tomoscan image.
Image co-registration: be mapped in another piece image by the pixel of piece image in described radar detection image and described tomoscan image, makes the fusion reaching unanimously to complete this two width image related like vegetarian refreshments on locus of two width images.
Specific implementation process is as follows: image co-registration includes multiple method: a kind of method is labelling method, in described radar detection image and described tomoscan image, the characteristic point place of image carries out labelling, the image tagged of described radar detection image and described tomoscan image is overlapped described radar detection image and described tomoscan image are merged, when image co-registration, the image tagged of described radar detection image and described tomoscan image is identified, then identification image is carried out image co-registration as boundary mark, identify image tagged feature, image co-registration can be made more accurate.In specific embodiment, after carrying out labelling, image is optimized, after segmentation, cut zone is carried out image co-registration.Image tagged software design becomes the boundary mark synthesized by the Feature point recognition of image as image.Image tagged software is according to labelling to the labelling of tissue identification, the labelling of lymph node identification and characteristic of described radar detection image and tomoscan image, coordinate axes is formed coincidence point, completing the fusion of described radar detection image and tomoscan image, the method is equally applicable to two dimension or the three-dimensional breast image that other modes combine.Further comprises the display to multi-modal microwave breast image, the two and three dimensions information of display breast, the labelling to focal area.Another kind of method is pixel weighted mean method, it may be assumed that the image pixel weighted average of described radar detection image and described tomoscan image correspondence position is completed image co-registration.
Below for labelling method:
Image registration
By using coupling, superposition etc. to process means, the same target in multiple image is kept same position in the picture so that it is there is the process of identical space coordinates.
In the microwave tomoscan image registration with microwave radar image, using metastable microwave tomoscan image as reference picture I, using microwave radar image as floating image II, carry out the image registration of the maximum mutual information method based on pixel, flow chart as shown in Figure 3 under:
Rigid body translation includes transformation of scale, in two-dimensional image I I, and point (x1, y1) through rigid transformation to point (x2, y2) application formula be:
Wherein, α is the anglec of rotation, and K is scale parameter.
Mutual information relevance evaluation.The gray value of two images subject to registration is regarded as two stochastic variable A and B respectively, and scope 0 to 255, marginal probability distribution is P respectivelyA(a) and PBB (), joint probability distribution is PAB(a, b), then edge entropy and the combination entropy that can obtain A and B are respectively as follows: H (A), H (B) and H (A, B).Then have:
Normalized mutual information dependent evaluation function I (A, B) of stochastic variable A and B, for:
When two width reach optimal registration based on the image of common anatomical structure, gray scale cross-correlation value of information I (A, B) of they respective pixel should reach maximum.
Registration optimizes.After rigid body translation completes, described image optimization module 53 is optimized, that is: a kind of similarity side degree is found to weigh the similarity degree of two width images, need continuous transformation parameter α and K, similar side degree is made to reach optimum, wherein scale parameter K excursion is 0 to 1, and rotation angle range is 0 to 180 degree.
1. it is the unit vector of coordinate axes: c by α and K transformation range seti=e (i=1,2 ..., N)；
2. record initial value position vector is P0=(α0, K0)；
3. to i=1,2 ..., N, by Pi-1Move to object function I (A, B) and prolong ciThe maximum position in direction, writes down this Pi；
4. to i=1,2 ..., N, by ci+1It is assigned to ci, juxtaposition cN=PN-P0；
5. by PNMove to object function I (A, B) at cNMaximum point on direction, and record the P of this point0；
6. repeat step 2. to arrive 5., until functional value I (A, B) no longer increases.
The preferred embodiment of the present invention is: also included carrying out Image semantic classification before carrying out image co-registration.
Microwave tomoscan image preprocess method is as follows: big by external interference factor based on microwave Tomography, Image semantic classification we utilize point processing to carry out the extension of contrast, making image clear, feature is obvious, it is assumed that original image f (x, y) tonal range is [a, b], and image g after conversion (x, what tonal range y) was linear extends to [c, d], then there is grey linear transformation expression formula is:
When the grey level distribution of pixel most of in image is in interval [a, b], fmaxFor the maximum gray scale of artwork, only the gray level of very small part has exceeded this interval, then in order to improve reinforced effects, and Wo Menling
By the linear stretch to image, it is possible to be effectively improved picture contrast effect.
Microwave radar image pre-processing method is as follows: owing to microwave radar imaging is except the intrinsic problem speckle noise existed, and there is also the bright spot high-frequency noise of random appearance simultaneously, and we utilize low pass Recursive filtering method that it is carried out pretreatment.
Assume the grey decision-making x of each pixel in the n-th width microwave radar imagen(i j) represents, α is correlation coefficient, then the image y after processingn(i j) is
yn(i, j)=α * yn-1(i, j)+(1-α) * xn(i, j) (4)
It is appreciated that by formula (4), the value of current each pixel is solely dependent upon the input of this pixel and the output of last time, unrelated with the value of other pixels, and we analyze its frequency characteristic by one-dimensional transform method, analyze the frequency response of each pixel self, namely have:
Y (n)=α * y (n-1)+(1-α) * x (n) (5)
Its transmission function is,
H (z)=Y (z)/X (z)=(1-α)/(1-α z-1)(6)
In l-G simulation test, value α is the amplitude-frequency characteristic of 0.2,0.6 and 0.8, and α value is more big, and radio-frequency component is repressed more severe, weakens speckle noise more obvious.
