Abstract
The utility model relates to elastic imaging equipment of a shearing wave interference method. The elastic imaging equipment comprises an equipment base frame, B-ultrasonic wave equipment, an ultrasonic probe, a left shearing wave source generation device, a right shearing wave source generation device and a shearing wave source drive system, wherein the shearing wave source generation device is fixed on the base frame; and the base frame is a quadrilateral frame, and both the upper edge and the lower edge are respectively provided with a wave source distance regulating and locking device. When the ultrasonic probe is worked, shearing wave interference can be provided by the elastic imaging equipment, and creeping waves with interference fringes are received by utilizing the ultrasonic probe; and then, the creeping waves are calculated through ultrasonic equipment so as to obtain the tissue hardenability of a detected body. The elastic imaging equipment can be used for quantitatively measuring the tissue hardenability distribution of the body in real time and helping doctors to better make accurate diagnosis on various symptoms. According to the elastic imaging equipment, the traditional ultrasonic equipment software framework is adopted, and acoustic radiation is not needed to push body tissues so as to effectively avoid possible damages generated by too high acoustic power.
Description
Technical field
The present invention relates to a kind of shearing wave interferometric method elastogram equipment, belong to the armarium technology, especially a kind of medical diagnostic equipment of ultra sonic imaging.
Background technology
The image-forming principle of conventional ultrasound imaging is based on ultrasound wave in backscattering and the reflection of body tissue the inside.A lot of focuses comprise that the formed backscattering of a large amount of cancers and reflection and health tissues difference are very little.This directly causes a lot of diseases to be failed to pinpoint a disease in diagnosis under ultra sonic imaging, mistaken diagnosis or be difficult to make a definite diagnosis.In order to improve the diagnosis accuracy of right various pathology, particularly cancer of ultrasonic image, the medical image scientific research personnel in forward position have proposed remembering with gratitude of elasticity iconography.In elasticity iconography the inside, the hardness of body tissue can by the showing of pointwise, form a series of images.With traditional image contrast, elastogram offers the brand-new body tissue information of healthcare givers, and can be the maximization of the difference of focus and health tissues, quantification.In global ultrasonic image field, the technology of ultrasonic elastograph imaging has been widely used and has been recognized has good diagnosis effect at present.Each high-end ultrasonic producer uses different technology to realize.Present classic technology is the shearing wave imaging method.Shearing wave spread speed in the medium of different hardness is different.Utilize ultrasonic the tracking to shear the distribution that wave propagation velocity just can instead push away body tissue hardness.The advantage of this technology is, thereby the hardness of measuring machine soma that can be quantitative is diagnosed more accurately.
But present shearing wave imaging method requires high to the hardware platform of ultrasonic device.Wherein most particularly its requirement can be satisfied the above ultrasonic framework of ultrahigh speed of per second 3000 frames.Under the restriction of this exacting terms, the whole world only has a ultrasonic enterprise really to realize 2 dimension shearing wave elastograms at present.
Summary of the invention
Be directed to above deficiency, the utility model proposes a kind of imaging device that utilizes shearing wave interferometric method elastogram.Present technique is such:
Shearing wave interferometric method elastogram equipment of the present utility model comprises equipment pedestal 8, B ultrasonic equipment 1, ultrasonic probe 3, it is characterized in that, it also comprises shears the wave source generating means; The middle part of equipment is detected the left side, room left shearing wave source generating means 6 is set, and be connected with left shearing wave source driving system 7 for detecting the room; The right side arranges right shearing wave source generating means 4, and is connected with right shearing wave source driving system 5; Ultrasonic probe 3 is movably arranged on the detection empty place.
As mentioned above, to this patent illustrate further into, left shearing wave source generating means 6, right shearing wave source generating means 4 all are fixed on the pedestal 8, pedestal 8 is quadrilateral frame, the up and down both sides of pedestal 8 respectively are provided with wave source distance adjustment locking device 2.
This utility model arranges two in ultrasonic device probe both sides again and shears the wave source generating means, and connect respectively a shearing wave source driving system, when ultrasonic probe is worked, can provide shearing wave to interfere, and the shearing wave of arranged on left and right sides provides different frequency, use ultrasonic probe to receive the Creeping Wave that has produced interference fringe, then by the calculating of 1 pair of Creeping Wave of ultrasonic device, can draw the hardness of organizing of the body that detects.
This equipment can be real-time, quantitative measuring machine soma hardness distribute.Can help the clinician better the various diseases that comprise tumor to be made Accurate Diagnosis
The existing ultrasonic device hardware architecture of the employing of this equipment
This equipment does not need acoustic radiation pusher soma, effectively avoids acoustical power too high to may injuring that tissue produces.
The specific embodiment
The spread speed of shearing wave in soft tissue that is to say with to organize hardness relevant, known and sheared velocity of wave propagation and tissue density's (approving generally that in the world tissue density is 103kg/m3) in the tissue, and the hardness of tissue just can have been determined.In order to measure the shearing wave propagation velocity, this patent proposes many vibration sources interference fringe measurement method, comes to obtain the Two dimensional Distribution of the body tissue hardness of real-time quantitative to organizing hardness to carry out the analysis of real-time quantitative by the interference fringe of shearing wave.
Following enforcement this patent, to be detected body and be placed in advance detection empty place of the present utility model, then open ultrasonic device, and open the shearing wave source driving system of arranged on left and right sides, drive two and shear the work of wave source generating meanss, thereby allowing ultrasonic probe scan the Creeping Wave of interference, again by calculating the local velocity of its Creeping Wave, just can accurately know the hardness of knitting of detected body, to determine the tissue health situation.
The up and down both sides of pedestal 8 respectively are provided with wave source distance adjustment locking device 2, can adjust two phase mutual edge distances of shearing the wave source generating means.
More than be exemplary description of the present utility model, the shape improvement that changes of carrying out in present technique all belongs to the present technique scope.
