Description
Technical field
The utility model relates to four-dimensional ultrasound imaging probe, is specifically related to a kind of four-dimensional ultrasound imaging probe.
Background technology
In ultrasonic image-forming system, if obtain four-dimensional image, just need to use special ultrasonic probe one four-dimensional ultrasound probe.Four-dimensional ultrasound probe is to add that by common ultrasonic transducer stepper motor and gearing form.Produce and swing around an axle when electric motor drives makes ultrasonic transducer, in the process swinging at ultrasonic transducer, transmitter module applies emitting voltage to ultrasonic transducer, make it to send ultrasound wave, by these echoed signals, ultrasonic image-forming system can construct the real time 3-D image of surveying position, i.e. four-dimensional image.
In the time material being polarized with extra electric field, the electricdomain of polycrystalline material can redirect to the direction being close with extra electric field nearby, but is subject to the restriction of domain boundary, does not often reach with external electric field in full accordly, and polarizability can only reach 60-70%; And monocrystal is because existing without domain, not limited by domain boundary, polarity can be in full accord with external electric field, and polarizability approaches 100%.The globality polarized state of monocrystalline, makes it under applied alternating field excitation, can only in polarised direction, produce simple longitudinal (thickness) vibration mode.And unlike polycrystal, in the time doing longitudinally (thickness) vibration, there is certain lateral vibration mode simultaneously.And this simple longitudinal (thickness) vibration mode of monocrystal must produce simple compressional wave in medium.Therefore by using single crystal probe to propagate the detection mode of simple compressional wave in media, be called " pure wave technology ".
Summary of the invention
The utility model has overcome an above-mentioned difficult problem, and a kind of four-dimensional ultrasound imaging probe that high-penetration ability and sharpness can be provided is provided.
The technical solution of the utility model is to provide a kind of four-dimensional ultrasound imaging probe, comprise pure wave transducer and drive the drive unit of described pure wave transducer, it is characterized in that: described pure wave transducer is provided with several and is arranged in the unit 2 of shaking of convex surface 3, described in the unit of shaking 2 comprise the first electrode slice and the second electrode slice and the single-chip between described the first electrode slice and described the second electrode slice that are oppositely arranged.
As preferred version, described single-chip becomes described convex surface 3 according to the arranged with interval of fluting 0.05-0.50mm.
As preferred version, described drive unit comprises the first motor and the second motor, described the first motor drives described pure wave transducer to rotate along its axle core, and described the second motor drives described pure wave transducer in its axial plane, to do fan-shaped rotary motion.
As preferred version, described the first motor and described the second motor are stepper motor.
As preferred version, the further described transducing scanner of the every step of described the second motor completes ultrasound emission and echo is accepted, and forms a fan-shaped tangent plane.
As preferred version, the every stepping of described the first motor once described pure wave transducer in its plane internal conversion one position radially.
As preferred version, described the first motor and described the second motor replace stepping.
As preferred version, after described the first motor rotates a circle, fan-shaped tangent plane forms conical three dimensions 7 described in several of described pure wave transducer scanning.
Four-dimensional ultrasound imaging probe of the present utility model, the drive unit that adopts the first motor and the second motor to combine makes the scanning angle of pure wave transducer and the displacement of each step all more accurate and flexible; The piezoelectric property of single-chip makes it can only produce compressional wave, has avoided producing shear wave and the therefore interference of coupling generation.
