Referring to FIG. 1, Fig. 1 is a kind of schematic diagram of the embodiment for the ultrasonic energy generating full-view image of the present invention. Ultrasonic energy 1 includes ultrasound scanner head 10, processing unit 20 and display unit 30.Ultrasound scanner head 10 can be in tested object 100 surface continuously obtains multiple black-and-white images and corresponding multiple chromatic images, and wherein tested object 100 can be people The institutional framework at the positions such as the dynamic of body or the tissue, such as heart, blood vessel of static state.Processing unit 20 is then according to ultrasound scanner head Black-and-white image and chromatic image acquired by 20 generate output full-view image, and show the output panorama shadow by display unit 30 Picture.
Movement of the ultrasonic energy 1 of the present invention using ultrasound scanner head 10 on 100 surface of tested object, with time and position The variation set obtains a series of black-and-white image and a series of corresponding chromatic images, by this two series image information with Generate the reliable full-view image of ultrasound scanning.When determining characteristic image, pass through the black and white ultrasound video of different order Characteristic point compare with it is corresponding colour ultrasound video color compare, in obtained black-and-white image and corresponding colour A series of neutral characteristic image and corresponding color property image are filtered out in image.Wherein in embodiment, ultrasonic Probe 10 in obtaining multiple chromatic image C on tested object 100 is scanned with color Doppler Supersonic wave mode, be can measure The numerical value of the dynamic changes such as flow velocity, the intensity of dynamic organization's such as blood flow, and measured blood flow is distinguished with colored color Intensity or flow velocity.
Referring to FIG. 2, Fig. 2 is ultrasonic energy using Fig. 1 to generate the flow of the method 200 of ultrasonic full-view image Figure, its step are as follows:
Step 202:In obtaining continuous multiple black-and-white images and corresponding with multiple black-and-white image on tested object Multiple chromatic images;
Step 204:Determined in multiple black-and-white image and multiple chromatic image multiple neutral characteristic images and Corresponding multiple color property images;
Step 206:It is black and white full-view image by multiple neutral characteristic image joint, multiple color property image is spelled It is connected into as color panoramic image;
Step 208:The color panoramic image is superimposed on the black and white full-view image to generate an output full-view image;
Step 210:Multiple output full-view images that multiple different start time points generate respectively are shown as continuous Dynamic full-view image.
Please also refer to Fig. 3, Fig. 3 is the multiple black-and-white images and corresponding multiple chromatic images acquired by ultrasound scanner head Schematic diagram.As described in step 202, using ultrasound scanner head 10 in continuously obtained on tested object 100 multiple black-and-white image B with And after corresponding multiple chromatic image C, then processing unit 20 executes the work of step 204~208.In step 204, Processing unit 20 determines multiple neutral characteristic images in multiple black-and-white image B according to mutual effective overlapping region, these The decision process of neutral characteristic image is also assert by the mutual effective overlapping region of the chromatic image corresponding to it, and is determined Chromatic image C corresponding to each fixed neutral characteristic image is also confirmed as a color property image.Step 204 is by one The black-and-white image B of series determines multiple neutral characteristic images and color property shadow with a series of corresponding chromatic image C As after, to select the image for being most appropriate for engagement, the splicing operation of step 206 is carried out.Then processing unit 20 is in step 206 In, multiple neutral characteristic image joints are become into black and white full-view image respectively, and multiple color property image joints are become Color panoramic image.During each characteristic image is spliced into full-view image each other, used in the seam crossing of characteristic image A kind of stitching algorithm keeps seam fuzzy, while retaining whole tissue line information, can be mixed using Alpha in embodiment Legal, Poisson mixing methods or multiband (Multi-band) mixing method are as stitching algorithm.Then in a step 208, by phase After corresponding color panoramic image is superimposed with each other with black and white full-view image, output full-view image is generated, and transfer to display unit 30 outputs, such as be presented on screen.
In addition it is noted that proceeding by step 202 in different time points, finally in the obtained output of step 208 The result of full-view image can also differ.Therefore, the output full-view image of different start time points is can be obtained using this characteristic As a result, the output full-view image that multiple different start time points generate respectively represents different moments corresponding tissue Structure.Such as ultrasound scanner head 10 starts multiple black-and-white image B continuously obtained and corresponding more in first time point A chromatic image C (steps 202) can be used to generate the first output full-view image (step 204~208), in the second time point The multiple black-and-white image B and corresponding multiple chromatic image C (steps 202) continuously obtained can be used to generate the second output Full-view image (step 204~208), and so on.Then as indicated in step 210, sequentially by these output full-view images Broadcasting can be shown as continuous dynamic full-view image on display unit 30, and can also suspend broadcasting and observe some The full-view image result of particular moment.
Illustrate the mistake that multiple neutral characteristic images and corresponding multiple color property images are determined in step 204 below Journey.Please refer to Fig.3 and Fig. 4, wherein Fig. 4 be Fig. 2 in step 204 determined in a manner of iteration (iteration) black and white with And the flow chart of the method for color property image, its step are as follows:
Step 302:First black-and-white image set in multiple black-and-white image is special as black and white reference images and black and white Image is levied, sets first chromatic image corresponding to it as colour reference image and color property image;
Step 304:Whether the last image of multiple black-and-white image and multiple chromatic image has been comparedIf It is then to execute the step 206, if it is not, thening follow the steps 306;
Step 306:Sequentially compare the degree of the black and white reference images and the overlapping region of subsequent black-and-white image;If this is black White reference image meets black and white preset value with the overlapping index of subsequent black-and-white image, thens follow the steps 308, if the black and white benchmark Image is unsatisfactory for black and white preset value with the overlapping index of subsequent black-and-white image, then executes step S306;
Step 308:Compare the image error between the colour reference image and the chromatic image of the corresponding black-and-white image;If The colour reference image meets colored preset value with the overlapping index of the chromatic image, 310 is thened follow the steps, if the colour reference Image is unsatisfactory for colored preset value with the overlapping index of the chromatic image, then executes the step 306;
Step 310:Be set separately the black and white reference images and the black-and-white image and the corresponding colour reference image with The chromatic image is neutral characteristic image and color property image;
Step 312:The black-and-white image of step 310 is set as the black and white reference images, and the chromatic image is set It is set to the colour reference image, and executes step 304.
In step 202 obtain as in Fig. 3 multiple black-and-white image B and corresponding multiple chromatic image C after, then according to Sequence inputs two black-and-white images, and opens whether black-and-white image has enough overlapping regions using fisrt feature algorithm comparison two.Example Such as in step 302, first using first black-and-white image B0 in multiple black-and-white image B as the benchmark compared, that is, will Black-and-white image B0 is set as black and white reference images and is also directly set as neutral characteristic image, and the chromatic image C0 corresponding to it It is then set as colour reference image and is also directly set as color property image.
Black-and-white image B0 (the first black-and-white image) as black and white reference images be then then used to sequentially with it is next Each black-and-white image B compares the degree of overlapping region between the two one by one, that is, using iteration mode by the two of input Black-and-white image is opened to compare and (sequentially compare black-and-white image B0 and black-and-white image B1, black-and-white image B0 and black-and-white image B2 ...).Example Such as, in embodiment, algorithm can be aligned using ECC (Enhanced Correlation Coefficient) image as the One characteristics algorithm obtains the overlapping region of two black-and-white images in a manner of calculating transfer matrix, in other embodiment, also may be used With use swift nature detection method (FAST, Fast feature detector), scale invariant feature transfer method (SIFT, Scale invariant feature transfer) or acceleration robust feature method (SURF, Speeded up robust Features) it is used as fisrt feature algorithm.After each iteration, until black-and-white image B0 and another subsequent black-and-white image (step 306) when the overlapping index (degree of overlapping region) of Bm (the second black-and-white image) meets black and white preset value, that is, it is black There is between image B0 and black-and-white image Bm enough overlapping regions in vain, there are enough information contents to compare the more of chromatic image General Le effect.
Then, by the image overlap range obtained by black-and-white image B0 and black-and-white image Bm, second feature algorithm comparison is utilized Image between chromatic image C0 (the first chromatic image) and the chromatic image Cm (the second chromatic image) of corresponding black-and-white image Bm Error (step 308), whether the error (Chong Die index) actually calculated between chromatic image C0 and chromatic image Cm is enough low, I.e. it is overlapped whether index also meets colored preset value.If so, indicating the Doppler response of chromatic image C0 and chromatic image Cm It is worth fairly close, blood flow velocity or intensity are quite similar, then black-and-white image Bm and corresponding chromatic image can be confirmed by arriving this Cm can be set to neutral characteristic image and color property image (step 310).For example, in embodiment, can utilize flat The square theory of error (Least Square Error Method) is as second feature algorithm to calculate the mistake between two chromatic images Difference, and judge whether the error calculated is less than the colour preset value.In other embodiment, random sampling can also be used Consensus method (RANSAC, Random sample consensus) and gradient descent method (Gradient descent) are as the Two characteristics algorithms.
It illustrates, if the chromatic image C0 and chromatic image that are obtained in step 308 with second feature algorithm When error between Cm is not below the colour preset value, then it represents that this chromatic image Cm is not appropriate for being used as the shadow of splicing As (the black-and-white image Bm corresponding to it will not be also used), therefore step 306 is returned to, continues next iteration and compare, Such as compare black-and-white image B0 and black-and-white image Bm+1 ... and so repeat step 306, step 308, until obtaining foot as described above Using the black-and-white image and chromatic image as characteristic image.
Confirming that black-and-white image Bm (the second black-and-white image) and chromatic image Cm (the second chromatic image) is respectively black and white spy After levying image and color property image, then in next cycle, using black-and-white image Bm and chromatic image Cm as New black and white reference images and colour reference image, and repeat to be compared with subsequent image by the flow step 304 It is right, to the last a black-and-white image and chromatic image.For example, in being recycled at second, as black and white reference images Black-and-white image Bm (the second black-and-white image) between the two overlapping refer to sequentially is compared with next each black-and-white image B Mark, until black-and-white image Bm meets black and white preset value with the overlapping index of subsequent another black-and-white image Bn (third black-and-white image) When (step 306), then compare the chromatic image Cn (thirds of chromatic image Cm (the second chromatic image) and corresponding black-and-white image Bn Chromatic image) between overlapping index (step 308) whether also meet colored preset value, if so, confirm black-and-white image Bn with Corresponding chromatic image Cn can be set to neutral characteristic image and color property image (step 310).Then again with black and white Image Bn (third black-and-white image) and chromatic image Cn (third chromatic image) is as new black and white reference images and colored base Quasi- image carries out the comparison of third cycle, to the last (step 304) until a black-and-white image and chromatic image, is so It can determine by the multiple black-and-white image B captured and in multiple chromatic image C multiple neutral characteristic images and corresponding more A color property image (step 204).
After above-mentioned method, processing unit 20 can be by multiple black-and-white image B acquired by ultrasound scanner head 10 Multiple neutral characteristic images and multiple color property images are determined with corresponding multiple chromatic image C, and are spliced into respectively black White full-view image and color panoramic image, and black and white full-view image and color panoramic image mutually coincide to can be obtained colour more This colored output full-view image is finally presented on display unit 30 by general Le full-view image again.
