Detailed description of the invention
Fig. 1 is the schematic diagram of this utility model elastomeric check apparatus embodiments one, and as shown in Figure 1, this elastomeric check equipment comprises:
Processor 1, imaging device 2, ultrasonic transducer 3 and sting device 4;
Described ultrasonic transducer 3 is connected with described processor 1, obtains the information from objective pattern of tissue and the resiliency characterizing information of described tissue for detecting;
Described imaging device 2 is connected with described processor 1, for under the control of described processor 1, obtain morphological image and the elastic image of described tissue respectively according to described information from objective pattern and described resiliency characterizing information, and in described morphological image, merge the described elastic image of display;
Described sting device 4 is connected with described processor 1, for the guiding according to the image after fusion, determines puncture position, carries out puncture sampling to described tissue.
Particularly, the number of described ultrasonic transducer 3 is one or two.
The elasticity of biological tissue and the biological characteristics of focus are closely related, and the diagnostic procedure for disease has important reference value.But the traditional medicine image mode comprising x-ray imaging, ultra sonic imaging, nuclear magnetic resonance (MRI), computed tomography (CT) etc. all directly can not provide the information of the basic mechanical attribute of this tissue of elasticity.
In the present embodiment, elastography is adopted to carry out the resiliency characterizing information of detection by quantitative tissue.Its ultimate principle to organize applying inside (comprising self) or outside dynamic/static state/quasi-static excitation, under the effect of the physics law such as Elasticity, biomechanics, organize generation one response.Because the coefficient of elasticity (stress/strain) of different tissues (comprising normal and pathological tissue) is different, after being subject to external force pressure, its strain size is also different.To organizing the ultrasonic signal/image before and after deformation to process, obtain the elastic characteristic parameter of tissue, then by color map, the elastic characteristic parameter values map of tissue is become gray scale or coloured image, thus location pathological changes.
In the present embodiment, in existing tissue elasticity checkout equipment except realizing the detection to tissue elasticity characteristic information, be also integrated with the measuring ability of tissue morphology characteristic information, jointly to be supported for tissue needle biopsy provides to locate by elasticity and shape information.Thus not only can carry out normal tissue elasticity detection, but also tissue elasticity detection transmitting tissue can be utilized to carry out aspiration biopsy, be conducive to the integrated and specialized of equipment, be conducive to the accuracy rate improving aspiration biopsy.
Specifically, in the present embodiment, elastic displacement information and the information from objective pattern of tissue can be obtained by one or two ultrasonic transducer 3, and then obtain the morphological image of tissue and the elastic image of corresponding scanning plane.
For morphological image, ultrasonic transducer 3 utilizes piezoelectric effect to launch ultrasound wave, can reflect when ultrasound wave is propagated in the tissue, scattering, the physical phenomenons such as diffraction, ultrasound wave and the ultrasonic echo of reflection and backscattering are received by ultrasonic transducer 3, it is the signal of telecommunication that ultrasonic transducer 3 recycles inverse piezoelectric effect by the Ultrasonic transformation received, preprocessor 1 utilize AD to sample, Wave beam forming, envelope detected, the signal processing modules such as logarithmic compression carry out morphology imaging control to tissue, finally on imaging device 2, carry out gray scale imaging, obtain the GTG morphological image of tissue.
For elastic image, by to organizing applying inside (comprising self) or outside dynamic/static state/quasi-static excitation, deformation can occur under being organized in excitation, the degree that deformation occurs tissue is relevant with the hardness and elasticity organizing self.Utilize ultrasonic transducer 3 to detect ultrasound echo signal before and after deformation, suppose to be respectively S1 and S2, so just there is a temporal skew and time shift between signal S1 and signal S2, or be embodied in the skew of frequency and the skew of frequency displacement or phase place and phase shift.Processor 1 utilizes time domain cross-correlation, spectrum cross-correlation, square error and, SPECKLE TRACKING, scale invariant feature point is followed the tracks of, dynamic programming, zero crossing is followed the tracks of, the signal processing methods such as peak value searching can detect this time shift/frequency displacement/phase shift, thus measure deformation and the displacement of tissue, the information such as strain, recycling empirical equation can calculate the elastic characteristic value of tissue, described elastic characteristic value comprises displacement, strain, shear wave velocity, shearing wave attenuation quotient, modulus of shearing, Young's modulus etc., finally controlling imaging device 2 utilizes color map that the elastic characteristic value of tissue is mapped to GTG or coloured image, obtain GTG or the color elastic image of tissue.
Wherein, when using same ultrasonic transducer, because same ultrasonic transducer corresponds to the same scanning plane of tissue, can synchronously obtain the elastic image matched with morphological image.

And then, in the morphological image of tissue, merge the elastic image of display organization.Elastic image with the resiliency characterizing information of color-coded GTG or coloured image mode display organization, with the resiliency characterizing information that the diverse location of different colors or GTG representative tissue is corresponding, such as elasticity number.The morphological image of tissue shows with gray scale image, with the information from objective pattern that the diverse location of different GTGs representative tissue is corresponding, and the silhouette markup such as organized point.By the resiliency characterizing information Overlapping display in GTG or coloured image in form gray scale image, the fusion realizing information from objective pattern and resiliency characterizing information shows.
Advantage after two kinds of image co-registration is to show information from objective pattern, can show elastic displacement information again, thus can more accurate display organization.Such as when morphological image can not know display organization border, elastic image can make up; Partial volume effect causes morphological image can not distinguish some subtly when organizing for another example, and elastic image can as auxiliary, because the elasticity number of different tissues has different features; Further, elastic image can also display organization inside hardness distribution, therefore when reality punctures, the guiding of puncture needle being thrust to organization internal has important function.
What deserves to be explained is, the result of fusion is: in same piece image, show information from objective pattern and resiliency characterizing information simultaneously, carries out fusion display by morphological image and elastic image.And, to ensure that the position be organized in two kinds of images matches before merging display.The resiliency characterizing information of tissue and the mode of information from objective pattern is obtained for by same ultrasonic transducer, this condition is easy to meet, obtain the resiliency characterizing information of tissue and the mode of information from objective pattern for by two different ultrasonic transducers, need to ensure that the locus of these two ultrasonic transducers, angle are relative to same scanning plane.
In the present embodiment, by obtaining resiliency characterizing information and the information from objective pattern of tissue, imaging obtains morphological image and elastic image respectively, thus according to the additive fusion result of elastic image and morphological image, jointly for the location of puncture position provides guiding, pathological tissues can be navigated to exactly, the reliability of aspiration biopsy is improved greatly.
