Background technology
In the radiating medical applications of high strength supersonic, for example in lithotrity or in the artificial fever therapy apparatus, requirement can change focus depth location in vivo.Require the shape of focus and service condition (the not size of calculus or downright bad tumor) separately to be complementary in addition, do the machinery exchange with respect to the position of health or to image-forming block and needn't change supersonic source for this reason.
The lithotrite that has variable-focus is for example open in German patent application prospectus DE 37 39 390A1.In this known lithotrite, the second pulse wave source belt passing round that has the annular surface of emission has the first pulse wave source setting of annular emission face.The impulse wave that the first pulse wave source is produced focuses on the acoustic lens of first focus to be positioned at water prerun section (Wasservorlauf strecke) with first pulse wave source mode separately.These lens are surrounded at the parabola of second focus by an impulse wave pack with the emission of the second pulse wave source.The first and second pulse wave sources can be controlled jointly or separately from each other, thereby can produce the impulse wave that has different focal positions.For focus being created in outside the lithotrite and, require paraboloidal mirror that big extending axially is arranged in order to obtain the overwhelming majority by loop pulse wave source emitting sound wave.Because the ultrasound wave that is sent by the first pulse wave source is propagated along all direction in spaces, and be not to propagate as parallel beam, the quality of the focus that is formed by the second pulse wave source is unsatisfied.
The axial location of the focus of pulsed ultrasonic wave for a change, a kind of focusing arrangement that adopts is disclosed at european patent application prospectus EP0 486 815 A1, it is full of fluidic gap and is constituted by a plurality of, its interface be shape flexibly, thereby its profile and the performance that forms thus can change by charging quantity.
European patent application prospectus EP 0 421 290 A1 disclose a kind of pulsed ultrasonic wave transducer, and it is made of a plurality of sectors, and their sides respect to one another can tilt or change the distance of its opposite side.Each of these sectors produces the focus of a point-like, stretches thereby obtained variable focal area when the stack of the impulse wave that is produced respectively by these sectors.
Above the shortcoming of last-mentioned two kinds of devices be: for a change focus requires mechanically to change over the picture physical dimension.
As a kind of substitute mode, by J.Y.Chapelon at " The Feasibility of Tissue Ablationusing High Intensity Electronically Focussed Ultrasound ", Proceedings IEEEUltrasonic Symposium, the 1211-1214 page or leaf discloses a kind of annular array, its one transducer unit can control on Phase delay ground, thereby depth location that can focusing carries out electrical adjustment.Yet a kind of like this phase array controlled see technically and take a lot of trouble.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of device that is used to ultrasonic therapeutic to produce ultrasonic radiation, and it can change focal position or focus shape easily when keeping high focusing quality.
According to the present invention, the technical scheme that solves the problems of the technologies described above is: the device that is used to ultrasonic therapeutic to produce ultrasonic radiation comprises a plurality of ultrasonic transmitters that can independently control each other, they produce the ultrasonic radiation that has the focus of differing from one another (promptly be positioned at diverse location and/or have different-diameter) separately, each ultrasonic transmitter has a supersonic source, for supersonic source has disposed lens that are arranged on close supersonic source emitting surface to focus on the ultrasonic radiation by its generation.Thereby if each ultrasonic transmitter is controlled separately, the focus supersonic radiation that then can utilize each ultrasonic transmitter to produce the high focus quality that is applicable to ultrasonic therapeutic is because these lens are arranged on the place near the supersonic source emitting surface.Concrete medical conditions focusing performance demands is only depended in the selection of the ultrasonic transmitter of each self-application, promptly at first is the depth location and the focus expansion of focus.Because a plurality of ultrasonic transmitters have the focus that differs from one another, just can satisfy that different medical treatment requires and the measure that needn't take to change structure with same device bothersomely.Because producing one, each ultrasonic transmitter self can do bothersome phase retardation control with regard to unnecessary to a plurality of ultrasonic transmitters in addition for the focus supersonic radiation of treatment usefulness.In addition, thus have flat emitting surface supersonic source simple in structure by utilizing lens to come imaging just may utilize.
Especially, when the platycelous lens are used in combination with the supersonic source that has flat emitting surface, preferably make its plane towards associated supersonic source.This can make the compact conformation of this device, and (being flush ground) is coupling in emitting surface because lens can be directly.
In another kind of preferred implementation, the lens that belong to different ultrasonic transmitters are made from a variety of materials.
If ultrasonic transmitter has one around the rotational symmetric surface of emission of a shared central shaft, and these emitters produce a focus that is positioned on this common center axle separately, then can realize a kind of special compact structure.
In addition, above-mentioned technical problem can also solve like this: the device that is used to ultrasonic therapeutic to produce ultrasonic radiation comprises a plurality of ultrasonic transmitters that can independently control each other, they produce the ultrasonic radiation that has the focus of differing from one another separately, wherein each ultrasonic transmitter has a supersonic source, and this supersonic source has the emitting surface of a bending to focus on the ultrasonic radiation by its generation.Replace adopting lens to produce focusing, adopted just to have the supersonic source of crooked emitting surface at first, make to focus on by its ultrasound wave that sends.

The specific embodiment
According to Fig. 1, a kind of device that is used to ultrasonic therapeutic to produce ultrasonic radiation U1, U2, U3 comprises a plurality of ultrasonic transmitter S1 to S3, and they are around the coaxial setting of a shared central shaft A, and has around this rotational symmetric surface of emission.Each ultrasonic transmitter S1 to S3 comprises a supersonic source Q1 to Q3 who has a planar transmit face.Being positioned at intermediary supersonic source Q1 has a discoidal surface of emission, and be positioned at outside supersonic source Q2 and Q3 the annular surface of emission is arranged respectively.For each supersonic source Q1 to Q3 has disposed a plano-concave acoustic lens L1 to L3, its recessed surface has different radius of curvature each other, thereby the focal point F 1 to F3 that belongs to ultrasonic transmitter S1 to S3 respectively is positioned at different locus each other on this common center axle A.It is annular being positioned at outside lens L2, L3, is made of a plano-concave shape disk and be positioned at intermediary lens L1.Lens L1 to L3 is provided with near the mode of supersonic source Q1 to Q3 with its plane surface, promptly at interval less than 10cm, the preferred interval scope 0.1 and 4cm between.
Ultrasonic transmitter S1 to S3 can control separately, thereby has obtained different focal depth position (focus of ultrasonic radiation U1 is F1 in the drawings) according to the control ultrasonic transmitter of selecting (being S1 among the figure).If a plurality of ultrasonic transmitter S1 to S3 are controlled simultaneously, then the variation of locus and the expansion of focal area have been obtained according to selected ultrasonic transmitter S1 to S3.
In replacement embodiment as Fig. 2, the coaxial arrangement that replaces the lens of different curvature radius, coaxial lens M1, the M2 that be provided with the recessed surface of same curvature radius, but the material that constitutes these lens has different spread speeds to ultrasonic, thereby also is different by focal point F 1 of their generations and the locus of F2 in this case.
In embodiment as shown in Figure 3, coaxial arrangement ultrasonic transmitter S1 and S2 are for their supersonic source Q1 and Q2 only disposed a platycelous lens L.Though ultrasonic radiation U1 and the focal point F 1 of U2 and the depth location of F2 by ultrasonic transmitter S1 and S2 generation when adopting this device is identical, its stretching area yet (focus diameter or Focus length) is different, thereby can change this stretching area by selection or the combination of control ultrasonic transmitter S1 and S2.Iff the most intermediary ultrasonic transmitter S1 work, when the diameter d 1 of the focal point F 1 that then obtains work than external ultrasound emitter S2 greatly, the latter produces the ultrasonic radiation U2 that its focus has smaller length and less diameter d 2.
For reaching desirable focusing, can allow the acoustic emission of supersonic source Q1 to Q3 self wear radius of curvature in principle and replace employed imaging device, as shown in Figure 4 expectation show like that.
In addition, the present invention is not limited to the coaxial annular layout of ultrasonic transmitter.In fact, as long as the ultrasonic radiation that a plurality of ultrasonic transmitters that the present invention comprises can be controlled separately and generation has different performance (focal position, Focus length or focus diameter) focus separately is just enough.
