The code-excited frequency range applied decodes corresponding ultrasound echo signal, and weights to decoded ultrasound echo signal laggard
Row Beam synthesis obtains Beam synthesis signal, and carries out ultrasound image according to the Beam synthesis signal and show.Below with specific
Ultrasonic imaging method is described in detail in embodiment.
Fig. 2A is a kind of the application embodiment flow chart of ultrasonic imaging method shown according to an exemplary embodiment, should
Embodiment can be applied on supersonic imaging apparatus, and as shown in Figure 2 A, which includes the following steps：
Step 201：Controlling Drive assembly is the code-excited of each array element application different frequency range in ultrasonic probe, so that
Each array element is generated and transmitted by ultrasonic signal using the code-excited of application.
Wherein, code-excited to can be linear FM signal (i.e. Chirp signal), and different frequency range it is code-excited in
Frequency of heart is different.It, can be with since the ultrasonic signal by code-excited generation can increase the energy of signal carrying
The average acoustical power for improving ultrasonic signal improves the penetration power (i.e. increase investigation depth) of signal.Those skilled in the art can
It can be passed through with understanding for each array element using the code-excited process for being generated and transmitted by ultrasonic signal of application
The relevant technologies are realized.
It is the coding that each array element in ultrasonic probe applies different frequency range for how to control Drive assembly in step 201
Excitation may refer to the description of following Fig. 3 A, wouldn't be described in detail herein.
Step 202：The ultrasound echo signal returned by ultrasonic probe is received, which penetrates for ultrasonic signal
After entering testee, by the signal of testee reflection.
Wherein, after each array element in ultrasonic probe launches ultrasonic signal, ultrasonic signal is injected tested
After object, testee meeting reflectance ultrasound echo-signal, at this point, each array element in ultrasonic probe can receive ultrasonic echo again
Signal.Since the code-excited frequency range applied to each array element is different, i.e., the code-excited center each array element applied
Frequency (average value of maximum frequency and minimum frequency in frequency range) is different, so that each ultrasound echo signal received is mutual
It does not interfere, improves the signal-to-noise ratio of ultrasound image, and then improve the contrast of ultrasonic imaging.
It should be noted that can reflect a ultrasound after each ultrasonic signal launched injects testee
Echo-signal comes out, the corresponding ultrasound echo signal of each ultrasonic signal, and after some array element transmitting ultrasonic signal, this is super
The corresponding ultrasound echo signal of acoustic signals may be received by other array elements.
Step 203：It is utilized as the code-excited of each array element application, decodes corresponding ultrasound echo signal.
In one embodiment, matched filtering first can be carried out to each ultrasound echo signal, to improve the signal-to-noise ratio of signal,
Then recycling is the code-excited of each array element application, decodes corresponding ultrasound echo signal, decoding formula is as follows：
xk(t)=xi(t)*xs(t), i=1,2 ... N
Wherein, xkIt (t) is decoded ultrasound echo signal, xi(t) corresponding super for the ultrasonic signal of array element i transmitting
Sound echo-signal, xs(t) represent be for array element i apply it is code-excited, * represent be convolution, N is array number.
Step 204：To Beam synthesis is carried out after the weighting of decoded ultrasound echo signal, Beam synthesis signal is obtained, and
Ultrasound image is carried out according to Beam synthesis signal to show.
In one embodiment, due to through the above steps 201 use ultrasonic coded excitation technologies can be improved ultrasound at
The contrast of picture, but its resolution ratio that can not improve ultrasonic imaging, therefore decoded ultrasound echo signal is added
Power processing, to improve the resolution ratio of ultrasonic imaging, for example, can believe by using Capon algorithm decoded ultrasonic echo
It number is weighted, the ultrasound echo signal after being weighted, then Beam synthesis is carried out to the ultrasound echo signal after weighting, specifically
Beam synthesis formula is as follows：
Wherein, YSFIt (t) is Beam synthesis signal, N is array number, xm,n(t) emit ultrasonic signal for n-th of array element, the
M array element receives corresponding ultrasound echo signal, τm,nFor the corresponding delay of ultrasound echo signal, wm,nTo be calculated by Capon
The weighing vector that method obtains.It will be appreciated by persons skilled in the art that finding weighing vector by Capon algorithm can pass through
The relevant technologies are realized.
In one embodiment, after Beam synthesis, bandpass filtering first can be carried out to Beam synthesis signal, and calculate filtering
Then the envelope of Beam synthesis signal afterwards carries out log-compressed processing to envelope again, obtains picture signal, finally believe image
Number carry out Denoising disposal, and according to after denoising picture signal show ultrasound image.
Wherein it is possible to calculate the envelope of Beam synthesis signal by Hilbert transform, and pass through two-dimentional mean filter method
Carry out Denoising disposal.
In an exemplary scene, Fig. 2 B is the ultrasound image obtained using the prior art, and Fig. 2 C is using code-excited
And the ultrasound image that the combination of Capon algorithm obtains, by comparing it is found that being obtained in conjunction with Capon algorithm using code-excited
Ultrasound image high resolution, and contrast is also high.
It is code-excited by applying for each array element in ultrasonic probe in the present embodiment, it is applied so that each array element utilizes
Add it is code-excited be generated and transmitted by ultrasonic signal, since the ultrasonic signal using code-excited generation can increase signal
The energy of carrying, therefore the penetration power of signal can be improved；Again since the code-excited frequency range applied to each array element is different,
So that each ultrasound echo signal received is not interfere with each other, the signal-to-noise ratio of image is improved, and then improves image
Contrast；Again due to the Beam synthesis carried out using weighting scheme, image resolution ratio can be promoted.It follows that this Shen
Please while with preferable image resolution ratio, picture contrast also with higher, to improve the matter of ultrasound image
Amount.
