In the present embodiment, ultrasonic probe 10 is all periodically to emit large deflection angle ultrasonic wave, the wherein tool of transmit cycle
Body setting is unlimited, and for how to be automatically performed the judgement of the large deflection angle degree to next period ultrasonic probe 10, the present embodiment
Realization principle specifically by first capture and identify current puncture needle 20 carry out puncture procedure during insertion be orientated (need
It is noted that puncturing enhancing image for more real-time display, can further shorten the transmit cycle duration of ultrasonic wave), in turn
It is counter to push away further according to the direction of the launch of ultrasonic wave under the large deflection angle degree relationship vertical with the insertion orientation of puncture needle 20 identified
Go out the large deflection angle degree of next period ultrasonic probe 10.
The big deflection image of a frame can generally be increased under existing puncture enhancement mode, as shown in Figure 4.In the present embodiment,

It is in the plane wave of plane or the broad beam of almost plane to include transmitting sound field corrugated within the scope of ultrasonic listening, wherein wide wave
Beam specifically refers to transmitting sound field wave beam within the scope of ultrasonic listening and shrinks wave beam that is limited and obviously not focusing.
In addition, in the present embodiment, module 403 is adjusted by large deflection angle, ensure that complete in each round image processing process
At later all can adjust automatically next round ultrasonic probe 10 emit large deflection angle ultrasonic wave when corresponding large deflection angle degree, to
The Continuous optimization of the enhancing display of puncture needle 20 is further ensured, and existing routine punctures the big deflection emitted under enhancement mode
The launch angle of angle ultrasonic wave is fixed, thus can not ensure that the ultrasonic wave direction of the launch is vertical with the insertion of puncture needle needle body orientation,
Thus enhancing display effect is poor.
In the present embodiment, since the orientation that is initially inserted into of puncture needle 20 is can be determined (namely just to open by user itself

Launch angle to corresponding ultrasonic wave be next round ultrasonic probe 10 emit it is corresponding big when large deflection angle ultrasonic wave
Deflection angle.
Wherein, it should be further noted that the insertion of the direction of the launch of ultrasonic wave and the puncture needle identified is orientated closely
Seemingly vertical is specifically determined by the practical transmitting deflection angle supported of ultrasonic system equipment, if the launch party of ultrasonic wave
It is vertical to that can be orientated with the insertion of puncture needle, then it is adjusted to the direction vertical with the insertion orientation of puncture needle, and if not
Can, then it is adjusted to the insertion with puncture needle and is orientated best approximately perpendicular direction.
In the present embodiment, emit large deflection angle ultrasonic wave in epicycle ultrasonic probe 10 to enhance display 20 image of puncture needle
In the case of, by increasing the specific waveforms ultrasonic wave of several different launch angles of transmitting, to which simplicity is rapidly completed to puncture needle
The identification that 20 insertion is orientated improves doctor and carries out puncturing operation into the insertion angle direction without fixed puncture needle 20
The flexibility ratio of operation.Meanwhile according to the transmitting of ultrasonic wave under the insertion orientation and large deflection angle degree of the puncture needle 20 identified
The insertion of direction and the puncture needle 20 identified is orientated vertical relation, and it is big partially to realize that adjust automatically next round ultrasonic probe 10 emits
Corresponding large deflection angle degree when corner ultrasonic wave to reduce the complexity for puncturing enhancing manipulation, and makes 10 institute of puncture needle
Corresponding ultrasonoscopy remains best enhancing display effect.
It is the refinement high-level schematic functional block diagram that one embodiment of intensifier is punctured in Fig. 1 with reference to Fig. 6, Fig. 6.Based on above-mentioned reality
Apply example, in the present embodiment, the puncture intensifier 40 further comprises：

When can enhance show the picture frame scan line, namely make scan image it is relatively sharp.
In the present embodiment, since each specific waveforms ultrasonic wave (such as plane wave) is directed to the puncture needle of special angle
20 detections, therefore the specific waveforms ultrasonic scanning of each angle only needs the part array element transmitting ultrasonic wave on ultrasonic probe 10
, and only need transmitting primary, without needing overlapping transmission as when conventional B ultrasound mode imaging, to greatly
Ground reduces the time of transmitting ultrasonic wave, improves image processing speed.Namely as shown in figure 9, in the present embodiment, the increasing
Add transmitting module 401 when the transmitting specific waveforms ultrasonic wave (such as plane wave) is scanned, is only sent out under same launch angle
Penetrate the primary specific waveforms ultrasonic wave.
In addition, after ultrasonic wave transmitting, tissue and the meeting of puncture needle 20 ultrasonic scatterer or are reflected back ultrasound
Probe 10, then echo data is converted into electric signal by each array element on ultrasonic probe 10, it is reconverted into digital letter by amplification

The respective pixel of rule spatial compounding image respectively assigns certain weight, and is overlapped in this radius region.It is big to ensure
Deflection image and natural fusion of the Conventional spatial combination picture on whole ultrasonoscopy.While in order to ensure that image connects in real time
Continuity when continuous display, the enhancing effect of current whole ultrasonic image frame can also be assigned certain weight and with upper one whole
The weight of ultrasonic image frame is averaged, so that continuously the display of whole ultrasonoscopy is more smoothly without lofty, promotion
The display effect of image.
