Abstract
The invention provides an ultrasonic diagnostic equipment and the method for controlling the ultrasonic diagnostic equipment. Three ultrasonic transmissions of positive, negative and negative polarities are executed for each of a plurality of ultrasonic scan lines on the basis of a predetermined rate period. Echo signals generated due to the respective ultrasonic transmissions are received at the same rate. For each scanning line, addition of the echo signal based on the first ultrasound of positive polarity to the echo signal based on the second ultrasound of negative polarity produces a normal mode image. Also for each scanning line, addition of the echo signal based on the first ultrasound of positive polarity to the echo signal based on the third ultrasound of negative polarity produces centesis mode image data. The produced images of normal and centesis modes are displayed in a predetermined manner.
Description
Technical field

Background technology
Ultrasonic equipment for medical diagnosis is a kind of medical imaging devices, and it utilizes the ultrasonic pulse echo method non-invasively to obtain the faultage image of live body soft tissue from the surface of health.Compare with other medical imaging devices, ultrasonic equipment for medical diagnosis have size little, cheap, need not be exposed to X ray and have advantages such as tight security, and can carry out the blood flow imaging.Ultrasonic equipment for medical diagnosis is widely used in heart, abdominal part, urinary organs, and is used widely in department of obstetrics and gynecology etc.
When using ultrasonic equipment for medical diagnosis to carry out image-forming diagnose, as everyone knows, by extracting the harmonic component that the nonlinear waveform of organizing is propagated and the Non-Linear Vibration of contrast agent causes (the more higher harmonic components that occurs at the frequency place of fundamental frequency integral multiple) and making it imaging, can generate the very high-quality image that shows high-resolution and almost do not have pseudo-shadow (pseudo-shadow noise).Method as deriving the harmonic component that nonlinear component causes such as Non-Linear Vibration is typically filtering method.
In addition, for example at Iwao Abiru and Tomoo Kamakura " NonlinearPropagation of Ultrasonic Pulses " (Technical Report of the Instituteof Electronics, Information and Communication Engineers, US89-23, p53) set forth in, known that a kind of and above-mentioned filtering method is compared by more effectively removing fundametal compoment to extract the method for harmonic component.This method is such: two kinds of anti-phase ultrasonic pulses alternately are transmitted into identical ultrasonic scanning line mutually, will add up corresponding to two kinds of received signals of emission ultrasonic pulse.This method is called as " phase inversion method ".This method is a kind of very valuable technology: it is carried out fundametal compoment and offsets operation, thereby allows to remove the fundametal compoment that enters harmonic band that filtering method can't be removed; On the contrary, for harmonic component, it shows and adds and potentiation.
On the other hand, phase inversion method is under the immobilized situation at the tissue as propagation medium only, perhaps under the final identical situation of in-house propagation path, could accurately work.Therefore, if this method is applied to actual live body (in live body, existence is the motion of the organ of representative with the heart), under the influence of described motion, between the received signal at two rate times intervals (rates), displacement occurs in various piece, the result is that first-harmonic still is not eliminated, and produces motion artifacts on image.
In addition, when the transmission interval (PRF (PulseRepetition Frequency, pulse recurrence frequency) just) of ultrasonic pulse adds long time, the displacement of each several part becomes bigger, and the influence of motion artifacts becomes stronger.Motion artifacts can cover the part of wishing observation, the serious simultaneously picture quality that reduces.Therefore, in phase inversion method, common way is to carry out a kind of design that prevents motion artifacts, for example PRF is provided with unnecessarily not longly.
Simultaneously, at the radiofrequency ablation art (RFA of conduct to the topical therapeutic of hepatocarcinoma, radiofrequency ablation) in, perhaps in the biopsy of checking the hepatocyte tissue, carry out the ultrasonic leading paracentesis widely, and the interested part that accurately punctures is very important such as tumor.Therefore requirement can grasped the position that in vivo will insert puncture needle during puncturing beyond the question on the ultrasonography.

Below in conjunction with accompanying drawing four kinds of embodiments of first kind of embodiment to the of the present invention are described.Explanation in passing, in the following description, the ingredient with essentially identical function and structure has identical Reference numeral, only in the occasion of necessity, will they be repeated in this description.
(first kind of embodiment)
Fig. 1 illustrates the configuration block diagram according to the ultrasonic equipment for medical diagnosis of this embodiment.As shown in the figure, this ultrasonic equipment for medical diagnosis is made of ultrasound probe 1, memory element 30, input block 7, monitor 25 and equipment body 50.
Ultrasound probe 1 generates ultrasound wave and launches ultrasound wave to the patient, receives from the echo of patient's body internal reflection and generates echo-signal.It has piezoelectric transducer.These piezoelectric transducers are acoustic-electric reversible transducers of piezoelectric ceramics or similar material.Described a plurality of piezoelectric transducer parallel arranged is set at the end of ultrasound probe 1.
Input block 7 comprises LCD panel and input equipment on its control panel, such as keyboard, tracking ball, mouse and the special purpose interface of " the puncture pattern " that will describe below being used to carry out.Operator use input block 7 to carry out the input of emission/condition of acceptance (such as patient information and rate time interval (rate period) Tr), and the selection of image display mode, or the like.
Ultrasound wave receiving element 3 comprises that preamplifier 14, analog-digital converter 15, beam form device 16 and adder 28.Preamplifier 14 is designed to amplify the tiny signal that is converted to electrical receive signal by ultrasonic transducer, and guarantees gratifying signal to noise ratio.The fundametal compoment and the harmonic component that are enlarged into the received signal of predetermined amplitude in preamplifier 14 are converted to digital signal by analog-digital converter 15, and digital signal is sent to beam and forms device 16.16 pairs of devices of beam formation are converted into the received signal of digital signal and give the focusing time delay that is used to focus on from the ultrasonic reflections ripple of desired depth, and are used for the deflection time delay of scan patients by the receiving directivity that changes the ultrasonic reflections ripple in proper order.Adder 28 makes the resulting output that forms device 16 from beam through phasing addition process (phasing addition) (wherein, the received signal that obtains from predetermined direction is with the addition of homophase mode).
Harmonic extraction unit 4 comprises wave memorizer 17, adder/subtracter 18 and filter circuit 19.Wave memorizer 17 temporarily is stored in the received signal that the first time, emission/reception was obtained of predetermined direction therein.The received signal that preserve in the n time (wherein n is at least 2 natural number, supposes n=4) received signal that emission/reception obtained and the wave memorizer 17 second time of 18 pairs of predetermined directions of adder/subtracter is carried out addition or subtraction.On the other hand, filter circuit 19 is to reduce because the wave filter of thereby the fundametal compoment that can not by phase inversion method be eliminated former such as the motion of organ and the motion of health etc.
Based on the instruction of user from the relevant model selection of input block 7 input, emission/end etc., control circuit 6 is read emission/condition of acceptance and the dedicated program that is stored in the memory element 30, and the condition that its basis is read etc. is controlled individual unit and whole system statically or dynamically.

(puncture mode capabilities)
The puncture mode capabilities that ultrasonic equipment for medical diagnosis has is described below.This functional utilization phase inversion method is imaged as motion artifacts with the motion of puncture needle.In passing the explanation, in this embodiment, below such image-forming condition be called " puncture pattern ", under this image-forming condition: PRF is prolonged, intentionally generating motion artifacts, thereby strengthen the observability of puncture needle, although this is not suitable for the diagnosis of intravital image.In addition, the image-forming condition that is used for common diagnosis before this is called " general mode ".
Fig. 2 is the conceptual schematic view that is used to illustrate the scanning sequence of being carried out by the puncture mode capabilities.As shown in the figure, when carrying out imaging based on the puncture pattern, according to predetermined PRF each bar scanning line is carried out three ultrasonic emitting, wherein, polarity is just being become (moment t
1), negative (t constantly
2) and negative (moment t
3).Additional disclosure, the SP among Fig. 2
1, SP
2And SP
3The expression of simulation ground is by the spectrum waveform of the last echo-signal that ultrasonic emitting obtained.
Fig. 3 is the conceptual schematic view that is used to illustrate to the signal processing of the ultrasonic echo signal that obtained by the puncture mode capabilities.As shown in the figure, the general mode view data that is used for generating diagnostic ultrasonography (general mode image) for example generates by this way in adder/subtracter 18: for each bar scanning line, make echo-signal corresponding to the ultrasonic emitting first time (just at the moment of Fig. 2 t
1The hyperacoustic echo-signal with positive polarity) with corresponding to the echo-signal of the ultrasonic emitting second time (just at the moment of Fig. 2 t
2The hyperacoustic echo-signal with negative polarity) add up mutually.
By contrast, the puncture mode image data that are used for generating the ultrasonography (puncture mode image) of the motion that is used to grasp puncture needle generate in such a way in for example adder/subtracter 18: will corresponding to the first time ultrasonic emitting echo-signal with corresponding to the echo-signal of ultrasonic emitting for the third time (just at the moment of Fig. 2 t
3The hyperacoustic echo-signal with negative polarity) add up mutually.
Here, the difference that will discuss below is between the generation of the generation of general mode view data and the mode image data that puncture.The general mode view data is to use the PRF corresponding to common relatively short interval to generate.Therefore, it is lower to be attributable to ultrasonic emitting for the first time and the motion artifacts of the reasons such as motion of health produces between the ultrasonic emitting for the second time probability, and therefore can generate can be to the organ ultrasonography data of imaging suitably.On the other hand, puncture mode image data are to use the PRF corresponding to the length of the PRF length that is twice in the general mode view data to generate, therefore can generate can be suitably to the ultrasonography data of motion artifacts (being attributable to ultrasonic emitting and body kinematics that takes place between the ultrasonic emitting for the third time and puncture needle motion for the first time) imaging.
In filter circuit 19 and signal processing unit 5 subsequently, the general mode view data is handled through prearranged signal, and is shown as the general mode image on monitor 5.Equally, puncture mode image data are handled through similar, and are presented on the monitor 5 as the puncture mode image.
The schematic illustration of Fig. 4 an example showing of the ultrasonography carried out by the puncture mode capabilities.As shown in the figure, on monitor 5, as an example, show general mode image and puncture mode image side by side simultaneously.Operator confirm the position of puncture needle on the puncture mode image, can observe the state of organ simultaneously on the general mode image, and can handle this organ.Especially during operation, produce the brightness flop of ultrasonography sometimes by mobile a little puncture needle, thereby strengthen the observability of puncture needle.Because the puncture mode image is to use in time than two signals separating more usually and generates, compared with prior art, motion artifacts is showed more obviously.Therefore, compared with prior art, operator can be from the position of identification puncture needle on ultrasonography more definitely visually.
The schematic illustration of Fig. 5 another example of showing of the ultrasonography carried out by the puncture mode capabilities.As shown in the figure, on display 5, as an example, stack ground shows general mode image and puncture mode image, thereby can realize same purpose.
Explanation in passing in the puncture pattern, preferably makes dynamic range, gain, post-processed, the Flame Image Process projects such as (persistence) that persists is different from the Flame Image Process project in the general mode, to strengthen the observability of puncture needle.
In addition, even the peak value maintenance processing (maximum brightness value keeps handling) of carrying out the image that utilizes several frames individually in order when the motion of pin is stopped, also to keep observability, equipment can be designed as.
In addition, for the ease of the position of identification puncture needle, equipment can be designed as the color of at least a portion (zone that for example comprises puncture needle) with the puncture mode image and is shown as and is different from around this part or the color of general mode image.
(operation)
Operation under the puncture pattern of ultrasonic equipment for medical diagnosis is described below.The flowchart illustrations of Fig. 6 the stream of the treatment step under the puncture pattern, carried out.As shown in the figure, at first import (step S1) such as patient information, diagnosis parts, select imaging pattern (selecting " puncture pattern " here) (step S2).
Next, to in a plurality of ultrasonic scanning lines (scanning direction) each, according to predetermined rate time at interval, carry out three ultrasonic emitting (step S3) with positive and negative and negative polarity, (speed rate) receives the echo (step S4) that is caused and produced by each time ultrasonic emitting according to same frequency.
Subsequently, at each scanning line, will based on the first time positive polarity during ultrasonic emitting hyperacoustic echo-signal and based on the second time during ultrasonic emitting hyperacoustic echo-signal of negative polarity add up, thereby generate the general mode view data.In addition, at each scanning line, will based on the first time positive polarity during ultrasonic emitting hyperacoustic echo-signal and during based on ultrasonic emitting for the third time hyperacoustic echo-signal of negative polarity add up, thereby generate puncture mode image data (step S5).
Subsequently, show general mode image and puncture mode image (step S6) based on each view data that generates according to predetermined mode.
According to above-mentioned configuration, can obtain advantage described below.
According to this ultrasonic equipment for medical diagnosis, when utilizing the phase inversion method imaging, use at least two echos comparing interval De Gengkai in time at least with two echos that are used for diagnostic image (first image) to generate second image that intentional imaging goes out motion artifacts.For example when using puncture needle to handle,, just, can grasp the position of puncture needle more definitely than prior art by observing first image and second image of demonstration side by side or overlapping demonstration by using second image.As a result, this ultrasonic equipment for medical diagnosis can help to provide high-quality medical treatment.
In addition, according to this ultrasonic equipment for medical diagnosis, for the imaging of puncture needle, except at first selecting not need other operation the puncture pattern.Therefore, the ultrasonography that operator can observe wherein more definitely to the puncture needle imaging, and need not carry out any special operation, thus can alleviate operator's operation burden during operation.
In addition, can be realized by this way by the puncture mode capabilities of this ultrasonic equipment for medical diagnosis specific implementation: the dedicated program that will be used for this function of specific implementation is installed in existing ultrasonic system.Therefore, can realize safe puncture needle etc. easily and at low cost.
(second embodiment)
Second embodiment of the present invention is described below.This embodiment is: by further utilize rate time at interval subtractive method (rate subtraction method) carry out the imaging of the observability that strengthens puncture needle etc.Additional disclosure, " rate time is subtractive method at interval " is a kind of like this technology: utilize the difference between the same phase images (image of identical polar) to carry out imaging.This technology for example has description in JP-A-8-336527.
The conceptual schematic view of Fig. 7 is used to describe the scanning sequence of being carried out by the puncture mode capabilities according to second embodiment.In addition, the conceptual schematic view of Fig. 8 is used to describe the signal processing of being carried out by the puncture mode capabilities according to second embodiment to the ultrasonic echo signal.
As shown in Figure 7, for example, in a plurality of ultrasonic scanning lines each, with the ultrasonic pulse emission of positive and negative in other words, the positive polarity of reversed polarity three times.Explanation in passing, in the drawings, the echo-signal that obtains by ultrasonic emitting is expressed as SP with spectrum waveform respectively
1, SP
2And SP

In this embodiment, the same with first embodiment, based on echo-signal SP
1View data that addition obtains between (positive polarity) and the echo-signal SP2 (negative polarity) generates the general mode image.On the other hand, based on echo-signal SP
1(positive polarity) and echo-signal SP
3View data that subtraction obtains between (positive polarity) generates the puncture mode image.In this case, in the puncture mode image, in ultrasonic emitting the and not have part of motion not pass through the subtraction process imaging for the third time between the ultrasonic emitting first time.But, under the situation that puncture needle between twice has moved, use difference with remaining motion artifacts component suitably imaging come out.
By such configuration, can obtain the advantage identical with first embodiment, realize goal of the invention equally.
(the 3rd embodiment)

3The view data that addition obtained between (negative polarity) generates the puncture mode image.
Owing to insert empty rate time so at interval, compare with the situation of first or second embodiment, PRF can be prolonged a ultrasonic pulse emission.Therefore, can carry out imaging therebetween, can strengthen the observability of puncture needle the motion artifacts of the greater number that occurs.
Additional disclosure can be designed to this embodiment generate like this puncture mode image: carry out rate time interval subtractive method by ultrasonic waves transmitted for the first time and for the third time is provided with identical polarity.
(the 4th embodiment)

In the 3rd embodiment,, PRF can be prolonged a ultrasonic pulse emission owing to added empty rate time at interval.Therefore, can carry out imaging therebetween, strengthen the observability of puncture needle the motion artifacts of the greater number that occurs.
Additional disclosure, this embodiment also can be configured to generate like this puncture mode image: carry out rate time interval subtractive method by ultrasonic waves transmitted for the first time and for the second time is provided with identical polarity.
Explanation the invention is not restricted to above-mentioned embodiment in passing, when implementing, can realize by revise building block in the scope that does not depart from its purport.A kind of practicable modification in this way as described as follows.
(the 5th kind of embodiment)
The 5th kind of embodiment of the present invention is described below.In first to the 4th kind of embodiment each has all adopted and has prolonged PRF, deliberately generates the technology of motion artifacts with the observability that strengthens puncture needle, although this is not suitable for the in vivo diagnosis of image.By contrast, present embodiment will be explained a kind of like this imaging technique: in phase inversion method, for each scanning line, the time delay of wishing in the past after the benchmark ultrasonic emitting is after the T, execution is used for the ultrasonic emitting to the puncture needle imaging, thereby, be used for ultrasonic emitting by utilization to the puncture needle imaging, intentionally generate motion artifacts.
In the present embodiment, below such imaging pattern is called " manual puncture pattern ": wherein, intentionally generate motion artifacts by time delay T is set, thereby can strengthen the observability of puncture needle, even now is not suitable for the in vivo diagnosis of image.
The structure of block diagram of the ultrasonic equipment for medical diagnosis 1 of present embodiment and shown in Figure 2 basic identical.Describe below with the embodiment of having described in the different ingredient of function.
Control circuit 6 is read the dedicated program of storage in the memory element 30, and this program is expanded on the not shown memorizer, with the manual puncture of specific implementation mode capabilities.Describe the content of this function below in detail.
Ultrasonic emitting/receiving element 2 is carried out ultrasonic emitting/reception according to the setting launching condition under the manual puncture pattern.
Input block 7 is interfaces that T time delay that is used for will describing the back is set to needed value.
(manual puncture mode capabilities)
Manual puncture mode capabilities is described below.In this pattern, the benchmark ultrasonic emitting is set.It is selected as the time started of T time delay.As an example, in n the ultrasonic emitting that each bar scanning line execution is comprised at least paraphase (here, n represents to be at least 3 integer) situation under, first ultrasonic emitting or next-door neighbour are used for can being adopted to described benchmark ultrasonic emitting to the last ultrasonic emitting of the ultrasonic emitting of puncture needle imaging.
Explanation in passing, in this embodiment, in order to make explanation more concrete, supposed an example, wherein manual puncture pattern is applied to scanning sequence according to first kind of embodiment, just, in this example, under the situation of each bar scanning line being carried out three ultrasonic emitting comprising at least paraphase ultrasonic emitting of negative polarity (positive and negative), carry out the ultrasonic emitting that is used for the puncture needle imaging for the third time according to T time delay that sets with reference to ultrasonic emitting for the first time.But manual puncture pattern for example also can be applied to any one scanning sequence in second to the 4th embodiment, and need not stick to the example of being supposed.
The conceptual schematic view of Figure 13 is used to illustrate the scanning sequence of being carried out by manual puncture mode capabilities.As shown in the figure, when carrying out imaging,, carry out polarity and fallen to be (moment t just respectively in a plurality of scanning lines each based on manual puncture pattern
1), negative (t constantly
2) and negative (moment t
3) three ultrasonic emitting.Here, moment t
1With moment t
2Between interval be rate time at interval, t constantly
1With moment t
3Between interval be T time delay.Therefore, operator by predetermined operation with time delay T be set at required value, thereby can be according to carrying out the ultrasonic emitting that is used for the puncture needle imaging with the irrelevant at interval interval of PRF, can intentionally generate motion artifacts by the emission of this imaging ultrasound ripple, with to the puncture needle imaging.
The conceptual schematic view of Figure 14 is used to illustrate the signal processing of the ultrasonic echo signal that manual puncture mode capabilities is obtained.As shown in the figure, for example in adder/subtracter 18, generate the general mode view data be used to generate diagnostic ultrasonography (general mode image) in the following manner: for each scanning line, will corresponding to the first time ultrasonic waves transmitted (just at the moment of Figure 13 t
1The ultrasound wave with positive polarity) echo-signal with corresponding to the second time ultrasonic waves transmitted (just at the moment of Figure 13 t
2The ultrasound wave with negative polarity) the echo-signal addition.
By contrast, for example in adder/subtracter 18, generate the view data of the ultrasonography (manual puncture mode image) be used to generate the motion that is used to grasp puncture needle in the following manner: will be corresponding at moment t
1The emission the first time ultrasonic waves transmitted echo-signal with at moment t
1Pass by the ultrasonic waves transmitted for the third time of emission after the time delay T afterwards (just at the moment of Figure 13 t
3The ultrasound wave with negative polarity) pairing echo-signal adds up mutually.At filter circuit at different levels subsequently 19 and signal processing unit 5 the manual puncture mode image data that generated are handled through prearranged signal, thereby generated manual puncture mode image.The manual puncture mode image that is generated for example is presented on the monitor 5 in mode shown in Figure 4.
Here, for example generation of the puncture mode image data that obtain in the first embodiment, and between the generation of the manual puncture mode image data that obtain in the present embodiment, have difference as described below.It is that the echo-signal of twice ultrasonic emitting of the integral multiple (being two times in the first embodiment) of PRF generates that puncture mode image data are to use corresponding to interval.On the other hand, manual puncture mode image data then are to use following echo-signal to generate: corresponding at moment t
1First hyperacoustic echo-signal of emission, and corresponding at moment t

(the 6th kind of embodiment)
The 6th kind of embodiment of the present invention is described below.This embodiment strengthens the observability of puncture needle on the image.
The block diagram illustration of Figure 16 according to the configuration of the ultrasonic equipment for medical diagnosis of present embodiment.As shown in the figure, the ultrasonic equipment for medical diagnosis 1 of the present embodiment place that is different from the configuration of Fig. 1 is also to comprise graphics processing unit 40 and Doppler's processing unit 50.The ingredient that graphics processing unit 40 and other function are different from aforementioned content is described below.
Graphics processing unit 40 comprises variable gain amplifier 41 and image processor 42.Variable gain amplifier 41 is used to increase or reduce the gain of doppler image signal, and it for example is made of multiplication type digital to analog converter.Image processor 42 is that image generates auxiliary unit, its function is, utilization is carried out peak value to the signal that is identified as the expression puncture needle and is kept handling from the B mode image signal of signal processing unit 5 transmission and the doppler image signal that transmits from Doppler's processing unit 50, shows track then; Its function also has from the stroke of the trajectory predictions puncture needle that is obtained, and guides from dynamic(al) correction when the trip departs from the puncture lead.Here, image processor 42 changes the gain of variable gain amplifier 41, to reduce the color sensitivity of color flow picture.
In the back in the diagnosing sequence that will describe, radiating circuit 13 is according to meeting emission ultrasound wave such as the various potential pulses of finishing the launching condition of journey, tranmitting frequency.
Tomography (tomographic layer) after the conversion that image generative circuit 24 will be made of the item of information of each scanning line is divided into pixel, and each pixel is distributed to storage address, to store the reflex strength information of sectional analysis layer therein.In addition, for the puncture lead of the on position of describing to represent puncture needle, image generative circuit 24 is stored the some position of puncture lead therein, as data.
Doppler's processing unit 50 is by phase detecting circuit 51, analog-digital converter 52, mti filter 53, correlation unit 54 and constituting arithmetical unit 55 automatically, it extracts the component motion based on Doppler effect of blood flow component and puncture needle needle point, with Doppler image information projects such as the average speed that obtains a plurality of points, variance, power.By image generation unit 8 the Doppler image information project is sent to monitor 25, and by the colored combination image that is shown as average speed image, variance image, power diagram picture or these images.
(operation)
Below in conjunction with the operation of accompanying drawing description according to ultrasonic equipment for medical diagnosis of the present invention.
The flowchart illustrations of Figure 17 the operation in an embodiment of ultrasonic equipment for medical diagnosis of the present invention.In addition, the schematic illustration of Figure 18 A carry out during the puncture ultrasonography that on monitor 25, shows in the present embodiment.In addition, as a reference, in Figure 18 B, illustrate puncturing during, the ultrasonography of the prior art that on monitor 25, shows.
As shown in figure 17, when mobile puncture needle first (S1), Doppler signal is sent to image generation unit 8 from signal processing unit 5 and Doppler's processing unit 50.Doppler's processing unit 50 judges that relevant signal is the signal (S2) by the motion generation of puncture needle.
Shown in Figure 18 B, in the prior art, the image of puncture needle is buried in the image of live body, is difficult to discern puncture needle and where is positioned at.Therefore, shown in Figure 18 A, discern puncture needle like this: utilize to send to the signal of image generation unit 8 from signal processing unit 5 and Doppler's processing unit 50, speed under brightness under the B pattern and positional information project, the doppler mode, power and direction of travel information project, or the like, in image processor 42, carry out threshold determination.
Be used for discerning the threshold value of the judgement of puncture needle for image processor 42, as an example, following condition arranged:
(1) the brightness height under the B pattern;
(2) signal is near the signal the puncture lead;
(3) in doppler mode, comprise velocity component;
(4) direction in the doppler mode and puncture lead indicated direction basically identical;
(5) performance number is big.
The signal that satisfies above-mentioned some at least conditions is identified as puncture needle by image processor 42.In addition, threshold value is stored in the memory element 30, and under the situation of carrying out threshold determination, image processor 42 is read this threshold value from memory element 30.
Generally speaking, puncture needle only shows relative higher brightness at needle point (end portion), show lower brightness in other parts, so the image of puncture needle is buried in the image of live body.Therefore, under the situation that identifies the Doppler signal that satisfies above-mentioned condition (S2: "Yes"), then its to be identified as be to be produced by the motion of puncture needle, image processor 42 makes the B mode image signal of the needle point of puncture needle keep handling through peak value.Like this, the track of the needle point of puncture needle is regarded as the image of whole puncture needle.Therefore, it is more definite that the image of puncture needle becomes, even when the motion of puncture needle stops and no longer producing Doppler's component, also can know the position at puncture needle needle point place, and the residing state of whole puncture needle.It is to carry out (just under puncture needle such as inserts, stops and extracting at any state in all states) under any state of the puncture of carrying out with puncture needle that additional disclosure, the peak value of image processor 42 keep handling.In addition, when puncture needle moves, do not carry out Doppler measurement in the prior art.
Here, in the present embodiment, the puncture needle that identifies also can be handled through the colorize of image processor 42, thereby strengthens its observability.
In addition, when image processor 42 execution only showed the processing of the puncture needle tip portion of being discerned by B mode image signal with different colors, only the puncture needle needle point was emphasized, it is more clear and definite that the position that puncture needle has advanced to becomes.
The schematic illustration of Figure 19 in puncture needle inserts patient's body and when in patient's body, withdrawing from, carried out the puncture needle image that peak value keeps by above-mentioned processing.
When puncture, carried out puncture needle is inserted the part (" target tumor of puncture " among the figure) that will be punctured, and the series of after this puncture needle being extracted operation.Shown in the condition (3), when inserting puncture needle, doppler image signal has the component of the body surface left as described above, and when extracting puncture needle, doppler image signal has the component of convergence body surface.
Therefore, image processor 42 is carried out such processing: when inserting puncture needle, just, (S3 among Figure 17: "Yes"), as previously mentioned, the track of puncture needle (needle point) is left when doppler image signal has the component that leaves body surface; (the S3 among Figure 17: "No") when extracting puncture needle, just, when detecting doppler image signal and have the component of convergence body surface, keep the track of the puncture needle needle point that shows for carry out peak value by aforementioned processing, eliminate moving displacement component (S5 among Figure 17).
Like this, prevented from after extracting puncture needle, to stay the track of puncture needle.
Figure 20 illustrates sketch map in the following cases: when puncture needle departs from the angles of display of the lead that punctures, from the angle of dynamic(al) correction puncture lead, to show again.
Usually, under the puncture pattern, the image that is called as the lines (for example dotted line) of " puncture lead " by graphics processing unit 40 generates to be handled, and by control circuit 6 its stack is presented on the monitor 25 and (is superimposed upon on the ultrasonography), thereby the demonstration of these lines can be compared with the demonstration of the behavior of puncture needle (puncture needle inserts in patient's body or extracts in patient's body).
But in some cases, because the influence of in vivo tissue, puncture needle has distortion, and puncture needle is not according to advancing with the direction of puncture lead indication.
Therefore, carrying out linear regression by image processor 42 based on the track of the shown puncture needle needle point of aforementioned processing calculates or similar processing, control circuit 6 is based on the direction of advance of the prediction of result puncture needle of image processor 42 acquisitions, and proofread and correct the deviation of puncture lead, thereby on monitor 25, show the puncture lead again with respect to this prediction direction.
Particularly, so again show the puncture lead: control circuit 6 is indicated based on B mode image signal, puncture needle is the position of each on ultrasonography as time goes by, carrying out linear regression calculates, thereby find the position that will show the lead that punctures, thereby control circuit 6 lead that should puncture writes display image memory 23.Just, pointed puncture needle needle point each position (point) as time goes by of B mode image signal is regarded as statistical data, carry out calculating as a kind of linear regression of statistical disposition, thereby, can predict that puncture needle can be roughly along the straight ahead of the relation between the described point of expression, this straight line is shown as the puncture lead.
Like this, under the situation that the correction of the position of the puncture lead of the on position of manual ultrasonography that carries out puncture needle and indication puncture needle and angle is handled before the patient is punctured, man-hour can be shortened.In addition, owing to only just can proofread and correct the puncture lead, therefore can proofread and correct with cheap device by the linear regression counting circuit is set.
In addition, the puncture lead in the present embodiment also can be shown as formation two straight lines at any angle, rather than straight line.Here under the expected position and the situation of angle as corrected value that exceeds maximum lead through the position of gauged puncture lead and angle, equipment can be by showing that error messages come alert to proofread and correct once more.
As an example, even the puncture lead that is generated at image processor 42 at first is presented on the monitor 25 with 67 degree by control circuit 6, puncture needle is biased under the situation of 63 degree from 67 degree, angle by the sensing puncture needle, image processor 42 is carried out the processing that the lead that will puncture is corrected to 63 degree, control circuit 6 display result again on monitor 25, thus the direction of advance of puncture needle can be shown as the puncture lead.
In addition, at puncture needle very big departing from arranged, be biased under the situation of 50 degree from 67 degree with respect to the puncture lead, image processor 42 command monitor display message on ultrasonography is such as " can not accurately puncture ".Like this, the operator that known this message just have an opportunity to puncture again.
Because such demonstration, operator can confirm puncture needle with respect to significantly the departing from of puncture lead, thereby can prevent from the patient is produced injury.
The schematic illustration of Figure 21 in the present embodiment, when puncture needle is bent into shaped form, be presented at the puncture lead on the monitor.
As shown in figure 21, under the situation of puncture needle curved, based on the view data (coordinate information on ultrasonography) that control circuit 6 calculates by the execution quadratic regression or similar calculating (as the method for the deviation of proofreading and correct the puncture lead) obtains, the puncture lead of performance bending.
Equally, in this case, control circuit 6 based on B mode image signal indicated, puncture needle as time goes by each position (coordinate) on ultrasonography carries out quadratic regression and calculates.In addition, control circuit 6 will calculate the coordinate on ultrasonography that obtains and write display image memory 23, as curve puncture lead, and make monitor 25 show information in the above.Like this, even when puncture needle is bent into curve, control circuit 6 calculates the expectation stroke of puncture needles, and monitor 25 shows the trip, thereby can enough cheap device correction puncture leads.
