Technical field
The invention belongs to ultra sonic imaging Detection Techniques field, be specifically related to a kind of integrated small ultrasonic scanning image probe system.
Background technology
Ultrasound imaging probe is widely used in medical diagnosis and industrial detection system.The ultrasound imaging probe the most generally used mainly has two kinds:
One is to use multiple excess sound pressure electroceramics wafers, is arranged in array, makes each wafer launch ultrasonic and receive echo-signal the most successively, is carrying out data fusion later thus obtain ultrasonoscopy.The advantage of this system is not have machinery, and each wafer can be launched in time the most in turn, and detection time is fast.But, owing to the volume of pottery wafer is difficult to do little, limited ceramic wafer can only be placed in limited space.
Another kind of method uses double-shaft level electric machine control system, is fixed on motor by single-die ultrasonic probe, it is achieved moving horizontally of ultrasonic probe.Generally object to be imaged is positioned in tank, hangs from above by ultrasonic probe from level-regulating system, submerged in water, so that being coupled by water between ultrasonic probe with object under test.Controlled the position of probe by motor, carry out C-scan imaging.The advantage of this system is that probe displacement accuracy is high, it is possible to obtain higher imaging precision.But this systems bulky, and typically require to be placed in water object under test and just can be scanned imaging, use very inconvenient.
Summary of the invention
It is an object of the invention to the defect being to overcome above-mentioned prior art, it is provided that a kind of resolution integrated small ultrasonic scanning image probe system used high, convenient.
The integrated small ultrasonic scanning image probe system that the present invention provides, its structure includes: probing shell, X-axis screw rod, X-axis micromachine, Y-axis screw rod, Y-axis micromachine, control circuit, flexible signal line, miniature ultrasonic focus on wafer, coupling liquid.All parts are encapsulated in the probing shell of full coupling liquid；Wherein:
Control circuit is connected to X-axis micromachine, Y-axis micromachine and miniature ultrasonic by flexible signal line and focuses in wafer.Owing to during scanning imagery, motor and focus ultrasonic wafer all can carry out displacement, so using flexible signal line to be attached.Control circuit sends control signal, X-axis micromachine moves on X-axis screw rod, Y-axis micromachine moves on Y-axis screw rod in control respectively, thus realize the two-dimensional movement of focus ultrasonic wafer, and launch ultrasound wave in each displaced position control focus ultrasonic wafer and receive echo-signal, thus realize Ultrasonic C Scanning Image.
In the present invention, between the enclosure bottom and object under test of ultrasonic probe, scribble ultrasonic conducting couplant.First the ultrasound wave that focus ultrasonic wafer sends is transmitted to probing shell bottom surface in probe inside by coupling liquid, after ultrasound wave penetrates probing shell, is transmitted to object under test by the couplant smeared between object under test.The ultrasound echo signal of reflection couplant bottom probe and between object under test arrives bottom probe, then arrives focus ultrasonic wafer through the coupling liquid within probe, is converted to the signal of telecommunication by focus ultrasonic wafer.After pointwise collects echo-signal, it is transmitted to main frame and carries out imaging.
In the present invention, described probing shell can be circular, it is also possible to is square, rectangle or other suitable shapes.
In the present invention, described coupling liquid can be the water soluble polymer gel with electrical isolation capabilities and low acoustic attenuation coefficient.The ultrasonic conducting couplant that described couplant generally can use for ultra sonic imaging.
The present invention uses micromachine and miniature screw rod to constitute twin shaft mobile control system, miniature ultrasonic is focused on wafer and is fixed on y-axis motor；Shell fills special ultrasonic coupling liquid.By twin shaft mobile control system, control miniature ultrasonic focusing wafer and carry out two-dimensional movement detecting ultrasonic backscatter signal, carry out merging by the signal that all sensing points in whole displacement region obtain thus obtain ultra sonic imaging.Focusing on the displacement of wafer owing to micromachine can accurately control miniature ultrasonic, compared to supersonic array imaging system, the present invention is obtained in that higher resolution.Whole system is encapsulated in the shell of full coupling liquid, the advantage with integration and miniaturization.Present invention achieves the integrated design of ultrasound probe, can use as an independent ultrasonic probe, be a kind of convenience and the ultrasonic scanning system with high-resolution.
