Description
Technical field
The present invention relates to the system of selection of preset value in a kind of medical supersonic diagnostic device, especially a kind of diasonograph method for selecting preset value of image guiding.
Background technology
The ultrasonic echo imaging technique has been widely used in fields such as military affairs, medical treatment at present, by launching ultrasound wave to the target area, use receiving system to receive the echo-signal that reflects then, and by signal processing technology and image processing techniques, suppress the nonuseable part in the echo-signal, finally form the image of target area.
Following the closely bound up medical field of our everyone daily life, the ultrasonic echo imaging technique has obtained significant progress especially, present various medical supersonic diagnostic device such as B ultrasonic etc. have been widely used in the clinical diagnosis of each hospital, can observe the anatomical structure of patient's interior tissue and organ except traditional black and white is super, color ultrasound can improve the clinical application range of ultrasonic diagnostic equipment to endovascular blood flow imaging greatly by using Doppler effect.
In order to be controlled to the quality of picture better, all there are a lot of parameters can supply user (ultrasonic examination doctor) to regulate on the present ultrasonic diagnostic equipment, such as tranmitting frequency, transmitting power, dynamic range, gain, time gain compensation, penetration depth, pulse recurrence frequency, focal position or the like, the One's name is legion of these parameters, if all readjust in the time of patient of the each inspection of doctor, need the expensive time just can be transferred to the picture quality of optimization so.The patent of Hewlett-Packard " Ultrasound imaging system having userpreset modes " (U.S. Patent number: 5315999) proposed the method for a kind of preset value (Presets), difference according to check point, equipment has configured the value of all parameters in preset value when dispatching from the factory, the doctor only needs to select the picture quality that suitable preset value can be optimized when in use.In addition, the stored parameters value can also be revised according to practical situation by the doctor in the preset value, and perhaps the doctor can create the preset value of oneself.
Though preset value can improve doctor's work efficiency, still there is the problem of oneself to exist.Because preset value all be equipment vendors according to a large amount of representational patient's check image, therefrom select parameter by veteran doctor, makes the mass ratio of most of image optimize and obtain, so it only has the representativeness of a part.The preset value that obtains according to Chinese patient differs and is applied to U.S. patient surely, and vice versa.Even equipment only uses in a zone of a country, because the difference of individual patient, such as the difference of obese degree, weight, height etc., preset value also not necessarily can be applicable to each patient.Because the existence of patient's area differentiation and individual variation, so in actual clinical was used, the doctor still needed the workload of very big manual adjustment parameter.For veteran doctor, thereby the picture quality that the parameter of regulating preset value is optimized can be finished in the relatively shorter time, but for new hand or experience is not very abundant doctor, the adjusting of preset value is a very task of difficulty, they often do not know parameter, and how how this regulate and regulate effect afterwards, therefore will spend a large amount of time on adjusting parameter.In order to make the adjusting of preset value more directly perceived, can provide visual feedback to the doctor better, the patent of PHILIPS Co. " Automatic setup system and method for ultrasound imaging systems " (U.S. Patent number: 6951543) proposed the control method of the preset value parameter of a kind of image guiding, at first imaging is distinguished with the combination of all parameters in the position of examine, then the image that obtains is shown to the doctor according to different compound modes, the doctor passes through constantly to select oneself satisfied image, thereby carries out the selection of parameter combinations.Although this mode can provide reasonable visual feedback information to the doctor, make the doctor can probably know in advance become the quality of image, but very big problem is also arranged: at first, because parameter is numerous in the preset value, therefore different combinations is also a lot, to so many parameter combinations respectively imaging be unpractical; Secondly, allowing the doctor select for so many parameter combinations imaging, though be to carry out with a kind of visual way, also is very loaded down with trivial details.
Consider the problems referred to above, on ultrasonic diagnostic equipment, provide a kind of visual, use and method for selecting preset value efficiently intuitively, easily, thereby reduce doctor's workload, improve medical diagnosis efficient, be very significant.

The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
The present invention at first considers doctor's use habit, and when clinical examination, when he preserved piece image, it is satisfied to the current images quality that he is described, therefore preset value information at this moment is very important, and needs and image are preserved together; Next considers the check image before the patient, because every width of cloth image has all been preserved corresponding preset value information with it, therefore when same patient will carry out checking the second time to same position, can directly use the pairing preset value of check image last time; In addition, do, so the experience that in fact parameter value of the pairing preset value of image has contained this doctor inside because the check image before the patient may be the another one doctor.The present invention represents to the doctor by visual way by the image that doctor in the check image before the patient and this inspection has been preserved, and can allow the doctor under the guiding of these image informations, obtains own desirable preset value apace; In addition, the present invention can allow the experience propagation between the doctor more easy by corresponding preset value information in the check image before the patient being extracted with suitable means and being shown to the doctor.
As shown in Figure 1: all the ultrasonic diagnostic equipment with traditional is identical for most ingredient among the figure, difference only is that the preset value memorizer must be arranged, and the program difference in the controller, so the change that the present invention can do seldom on traditional ultrasonic diagnostic equipment can be implemented.In the following description, the ingredient of traditional ultrasonic diagnostic equipment has only provided brief explanation, focuses on to implement the special part of wanting required for the present invention.Transducer among the figure (also being probe) is hyperacoustic device that transmits and receives, and is generally made by piezoelectric, can convert electrical energy into acoustic energy, also can change conversely; Radiating circuit sends the signal of telecommunication to transducer under the coordination of controller, be converted to ultrasonic emitting by transducer and go out; Receiving circuit is responsible for receiving transducer and is passed the echo signal (being converted to the signal of telecommunication by transducer) come, and amplify, processing such as digital to analog conversion; Wave beam is synthetic to carry out dynamic focusing and dynamic aperture processing to the echo signal on the different directions, and it is synthesized together; The signal that signal processing and image form wave beam after synthetic carries out processing such as noise suppressed, envelope detection, logarithmic compression, digital scan conversion, forms the image that is easy to show at last; Display can be common CRT monitor or liquid crystal display etc., is responsible for image is shown and the demonstration of some user interfaces; Controller is responsible for all other parts are controlled and coordinated, and it can be a circuit, also can be an embedded device or a microcomputer.The controller of present most of digital ultrasound diagnostic device all is embedded device or the microcomputer that has operating system, the inside operation control sequence, difference along with control sequence, the function that ultrasonic diagnostic equipment showed is also inequality, and the back can provide the method described in the invention that how to realize in conjunction with the accompanying drawings in detail in controller; Keyboard is the front end of controller, and it is mutual to come with controller for a kind of means easily of user, and trace ball is all arranged on the keyboard of present most ultrasonic diagnostic equipment, is used for realizing the function with the mouse equivalence, and is user-friendly.A lot of command key are arranged on the keyboard, trigger corresponding function after the user presses.For enforcement of the present invention, necessarily require to have on the keyboard " preservation image ", " preset value selection " and " browsing passing image " these three command key, wherein " preservation image " and " preset value selection " these two buttons are the buttons commonly used on the ultrasonic diagnostic equipment, have on the general equipment.Need to prove that in the specific implementation, these three buttons not necessarily must have special-purpose button on keyboard, can be mapped as one of these three orders to the function of existing certain button on the keyboard; The preset value memorizer is mainly used to store the value of each parameter of preset value, can be divided into three parts: first is the preset value of equipment producer's prepackage when dispatching from the factory, and generally each check point is all provided a cover or has overlapped default preset value more; Second portion be the doctor in use, the relatively more suitable preset value of preserving that oneself uses, these preset values generally are on the basis of systemic presupposition value, the Several Parameters that the doctor regulates wherein is resulting, and operations such as the preservation of these preset values, name, deletion are all finished by doctor's manual operations; Third part is that the doctor is when checking patient, satisfied to certain width of cloth image or image sequence, when pressing " preservation image " button, system preserves the parameter value of currently used preset value get off automatically, and and the image preserved associate, the preservation of this part preset value is that system finishes automatically, does not need doctor's intervention.
Mostly provide preset value (Presets) that various imaging parameters are provided with on the present ultrasonic diagnostic equipment, Fig. 2 has provided the imaging parameters commonly used that is comprised in the preset value, just in order to describe and to illustrate, therefore the parameter of listing does not have exhaustive all possible imaging parameters to the purpose here.Imaging parameters commonly used roughly can be divided three classes: Image Acquisition parameter, display parameters, signal processing parameter.Front-end modules such as Image Acquisition parameter major control radiating circuit, receiving circuit, transducer, wave beam are synthetic, the value of these parameters is very relevant with patient's individual variation, relatively fatter such as a patient, the value of " penetration depth " parameter just must be more so, and the value of " tranmitting frequency " parameter just should be a little bit smaller.Rear module such as the formation of display parameters major control image, display, these parameters mainly influence brightness, contrast, amplification minification, pseudo-colour display screen that final image shows and show etc.; Signal processing parameter major control signal processing and image forming module, the signal that is used for to wave beam after synthetic is made various Filtering Processing, and the value of these parameters has bigger influence to picture quality.In general, the value of display parameters and signal processing parameter is smaller with the dependency of patient's individual variation, often default Default Value just can satisfy most of doctor's needs, but the doctor can regulate these parameters according to individual's the hobby and the quality of actual imaging, obtains a cover preset value that is fit to oneself use.Can see that from top description the dispatch from the factory preset value that carries of system can not satisfy each patient and each doctor's needs, still needs and will carry out a large amount of manual adjusting work, adjusting therefore how to simplify the preset value parameter is very significant.
As shown in Figure 3, wherein most of step all is to realize with program in controller.In step 1, system at first obtains examine patient's identity information.According to the function difference of used ultrasonic diagnostic equipment, this step can have a variety of implementations.In the manual user interface input system that information such as patient's name, sex, age are provided by ultrasonic diagnostic equipment of the most frequently used a kind of doctor of being, this mode does not need the ultrasonic diagnostic equipment networking, also do not need other special hardware and software, but probability of errors is than higher.If being equipped with, hospital meets HL7 agreement (Healthcare Level 7, the international standard of common therapy information network transmission) hospital information system (HIS), and ultrasonic diagnostic equipment is supported DICOM agreement (international standard of medical imaging network transmission), ultrasonic diagnostic equipment can be by the Worklist Query in the DICOM agreement so, Worklist server communication with hospital, and the Worklist server is communicated by letter with HIS by the HL7 agreement again, obtains patient's information from HIS.This method can be removed the trouble that the doctor imports patient information by hand from, but the degree that hospital information is built is than higher, and to the requirement of ultrasonic diagnostic equipment also than higher, in addition, when patient registers on HIS for the first time, still need the operator of HIS to import patient's information by hand, so still keep away the possibility of unavoidably makeing mistakes.If be equipped with Fingerprint Identification Unit on the ultrasonic diagnostic equipment (please referring to Chinese patent application " a kind of ultrasonic diagnostic equipment and method that has Fingerprint Identification Unit ", application number 200910025411.5), so just can utilize patient's finger print information to obtain patient's identity, this mode need not the doctor and imports patient information by hand, and because the maturation of fingerprint identification technology, therefore the probability of fingerprint comparison mistake is very little, in addition, Fingerprint Identification Unit is dirt cheap, can on common ultrasonic diagnostic equipment, use, the facilities such as HIS server that also do not need ultrasonic diagnostic equipment networking and hospital are convenient to implement very much; In step 2, patient status's information that the controller utilization obtains, this patient of inquiry had ultrasonic examination history before whether in the data base, if having, then changed step 3 over to, otherwise changed step 5 over to; In step 3, controller shows " passing picture browsing " dialog box on display, check image before the patient is shown with suitable manner, and allow the doctor to adjust back the pairing preset value of piece image, concrete details will 5 provide detailed description in the back in conjunction with the accompanying drawings; In step 4, controller judges whether the doctor has adjusted back a preset value, if readjustment, then execution in step 9, otherwise execution in step 5; In step 5, system enters waiting state, waits for that the doctor presses the button on the lower keyboard, and controller is handled accordingly; In step 6, if controller receives the KeyEvent that " preset value selection " button is pressed, then execution in step 7, on display, show " preset value selection " dialog box, the systemic presupposition value of storing in the preset value memorizer, doctor's preset value and patient's preset value are shown with suitable means, select for the doctor, concrete details will 4 provide detailed description in the back in conjunction with the accompanying drawings; In step 8, controller judges whether that the doctor has selected a preset value, if selected, then execution in step 9, otherwise execution in step 5; In step 9, controller the user is selected or the parameter value of the preset value of readjustment as the parameter value of current preset value, and enter step 10, carry out real time image collection with these parameter values; In step 11, controller writes down the modification that the doctor is done each preset value parameter automatically; In step 12, controller judges whether the doctor presses " preservation image " button on the lower keyboard, if press, then execution in step 13, otherwise execution in step 16; In step 13, controller is except preserving the image of current collection, also automatically the value of all parameters in the current preset value is preserved, and set up related with the image of preserving, can also preserve simultaneously doctor's information, so that knowing the preset value of this width of cloth image afterwards by which doctor is regulated out, thereby promote sharing and propagation of doctors experience, in addition, some of this preset value other general information with and source preset value and revise parameter and also all need to preserve in the lump, about general information, the source preset value, revise the detailed description of parameter, will 4 provide detailed description in conjunction with the accompanying drawings in the back; In step 14, controller generates a thumbnail to the image of preserving, and be presented at the inside, thumbnail zone of image real-time acquisition master interface below, for follow-up doctor's image readjustment or preset value readjustment, the back can be in conjunction with the accompanying drawings 6 detailed descriptions that provide image real-time acquisition master interface; In step 15, controller judges whether that the doctor adjusts back the pairing preset value of this width of cloth image in the thumbnail zone at image real-time acquisition master interface, if, then change step 9 over to, otherwise execution in step 16; In step 16, if the doctor feels to have obtained enough check image, can finish this inspection, controller judges whether that this inspection finishes, if, then withdraw from, continue to carry out otherwise change step 10 over to; In step 17, if controller receives the KeyEvent that " browsing passing image " button is pressed, then execution in step 2.
" preset value selection " dialog box as shown in Figure 4 shows during " preset value selection " button on by lower keyboard the doctor, the dialog box of similar functions is common on traditional ultrasonic diagnostic equipment, allows the doctor to select a suitable preset value to check.In general, the preset value 43 that the systemic presupposition value 42 of installing when this dialog box can be dispatched from the factory equipment, doctor preserve shows according to check point or inspect-type 41, the doctor selects different check points by mouse in 41, corresponding systemic presupposition value 42 and doctor's preset value 43 also can refresh thereupon, the doctor can select one with mouse in systemic presupposition value or doctor's preset value, begin to check.In addition, do not come though draw in Fig. 4, also can add the selection of probe here at an easy rate, probe is according to the difference of its purposes, can have different check point (perhaps inspect-type), general every ultrasonic diagnostic equipment all can be equipped with more than one probe.When the doctor was switched probe, the check point 41 among Fig. 4 also refreshed into this pairing check point of popping one's head in thereupon and gets final product.
For the method for this traditional selection preset value, be very not intuitively, the just name of these preset values that the doctor sees, image effect is how after using as for these preset values, without any information.This problem is particularly serious for the not too abundant doctor of experience, because he can only see systemic presupposition value and the preset value of preserving himself, can't see the preset value that other doctors preserve.Because to the preset value self-distrust of oneself preserving, therefore these doctors must select one from the systemic presupposition value, obtain some check image and viewing effect, if unsatisfied words, the parameter value of regulating system preset value, reuse " preset value selection " dialog box is selected another one systemic presupposition value, and this process is time-consuming very, and wants self-dependent groping fully.
The present invention makes full use of this important information of patient's check image in the past, adds the demonstration of patient's preset value 44 in traditional " preset value selection " dialog box.Patient's preset value is shown as two parts, above a part be that the patient of current examine carried out the image 45 that ultrasonic examination is preserved in the past, these images are also classified according to check point, only show the corresponding image of check point with current selection; A following part is that preset value describes 47, when the doctor uses after mouse chosen piece image in the above, can show the description of choosing the used preset value of image here.The doctor that is shown as of patient's preset value 44 provides visual preset value effect, and role mainly contains two here: the first, provide a kind of method of selecting preset value very intuitively, easily to the doctor.Suppose that a patient had carried out the ultrasonic examination of abdominal part before, the doctor can select the satisfied image of a width of cloth very apace in 45 so, click " selection " button 412 then or double-click image, thereby select the pairing preset value of this width of cloth image to check.Because what use is the preset value before of same patient, same check point, so the effectiveness that this preset value is selected can be fully guaranteed.In addition, consider that patient has check image before many at same check point, therefore in 45, during display image, must sort, thereby make things convenient for doctor's selection according to certain condition.Here show a slice 46 on the upper left side of every width of cloth image, the length of slice representing this width of cloth image the number of times that is employed of corresponding preset value, if slice is long more, just represent relatively good that the preset value of this width of cloth image regulates, the number of times that is employed is many, and what therefore also just show is forward more.Here need to prove,, do not illustrate that the preset value of this width of cloth image just has been employed once, because the doctor also may be in the value of some parameter of process intermediate regulations of checking if a doctor has selected the preset value of piece image to check.Therefore described preset value is employed the computational methods of number of times and is: suppose that preset value comprises N parameter altogether, when the doctor pressed " preservation image " button, the value of all parameters went on record inside this time preset value, uses p
1, p
2..., p
NRepresent; Suppose that the always total M of the passing image of patient opens, i opens the parameter value c of the pairing preset value of image
I1, c
I2..., c
INRepresent (1≤i≤M), and if only if p

2=c
I2..., p
N=c
INWhen satisfying simultaneously, we can say that just the preset value that i opens image has been employed once, the preset value that i opens image is employed number of times to be increased by 1 time.Second effect of patient's preset value is to be embodied in preset value to describe 47, when the doctor has selected piece image in 45 after, chooses the description of image corresponding preset value to be revealed.For better contextual information is provided to the doctor, preset value is described and is divided into three parts, and first part is that 48, the second parts of general information are that preset value 49, the three parts in source are for revising parameter 410.In general information part 48, the main holding time that shows the name of this preset value, doctor's name (being that this width of cloth image by which doctor is preserved), preset value etc., the name of preset value is generated when preserving image automatically by controller, general numeral number with order guarantees not repeat to get final product; In source preset value 49 and modification parameter 410 parts, show the evolutionary process of the preset value of current selection image in 45.
Described source preset value and modification parameter are defined as follows: if the doctor at first selects preset value A to begin to check, in the process of checking, regulated some parameter value among the preset value A, when system receives " preservation image " instruction (pressing " preservation image " button) as the doctor, the current preset value is saved as preset value B automatically, preset value A is called the source preset value of preset value B so, is called the modification parameter of preset value B with respect to preset value A with the different parameter of preset value A among the preset value B.Here it should be noted that two notions of " source preset value " and " modification parameter " all are relative, need the participation of two preset values.For patient's preset value, its source preset value has three sources: other patient's preset value of systemic presupposition value, doctor's preset value; For doctor's preset value, its source preset value has two sources: other doctor's preset value of systemic presupposition value; For the systemic presupposition value,, therefore there is not the source preset value because be when equipment dispatches from the factory, to install.Can draw from top analysis, if since patient's preset value, up review along the source preset value always, must arrive a systemic presupposition value at last, this systemic presupposition value is called the root preset value of this patient's preset value.The name of intermediary all source preset values of the root preset value from patient's preset value to it all is presented at source preset value 49 parts, and wherein arrow points to its source preset value from preset value.The doctor can select a preset value with mouse, the highlighted demonstration of preset value chosen this moment, and 48 and 410 refresh to choosing the information of preset value thereupon.If the preset value of choosing is patient's preset value, thumbnail 411 also demonstrates its pairing image so, gives the doctor with visual feedback; If the preset value of choosing is the systemic presupposition value, 48 be shown as blank so; If the preset value of choosing is the root preset value, 48 and 410 all be shown as blank so.The preset value of choosing is presented at 410 with respect to the modification parameter of its source preset value, and wherein each parameter occupies delegation, shows its value in choosing preset value and source preset value respectively.In clinical use, the modification parameter between preset value and the source preset value often can be not too many, so the doctor can understand the difference between two preset values very apace from 410.49 and 410 combine, the evolutionary process of complete patient's preset value is provided, and show in a kind of mode very intuitively, the doctor that experience is not too enriched is by this means, can be easily from those veteran doctors preserve the patient image of getting off, obtain valuable preset value and regulate experience, thereby improve the ability of oneself.
" passing picture browsing " dialog box as shown in Figure 5, the purpose that this dialog box is traditional is that current examine patient's check image in the past is shown to the doctor, the doctor can select interested image to browse, thereby obtains the more fully information about patient.All inspections that patient carried out have in the past been listed in passing inspection part 51 respectively according to patient's review time among the figure, because each inspection can be preserved many images, therefore for each inspection, listed the thumbnail of all images according to the time of image preservation.When the doctor chooses an image, click after " browse graph picture " button 52 then, system just closes " passing picture browsing " dialog box, amplifies then to show the image of choosing.In checking process, the doctor can press " browsing passing image " button at any time and open this dialog box once more.
Above described these functions all be traditional " passing picture browsing " function that dialog box provided, it does not carry out any operation to preset value.Because patient's passing check image provides very important preset value information, therefore here must utilize fully.The upper left corner of every width of cloth image that the present invention shows in 51 adds the number of times that a slice represents that the corresponding preset value of this width of cloth image institute is employed, the counterpart during specific explanations please illustrates referring to Fig. 4; In addition, also add preset value and describe part 54, when the doctor has selected piece image in 51 after, choose the pairing preset value of image to describe and just show, for doctor's reference or study.The specific explanations that preset value is described is please referring to the counterpart in Fig. 4 explanation; At last, added " readjustment preset value " button 53, after the doctor chooses piece image, can click this button, system closes " passing picture browsing " dialog box automatically, enters the image real-time acquisition state, and chooses the pairing preset value of image to be set to the preset value of current application.
