The specific embodiment
Describe each related detailed problem in the technical solution of the present invention in detail below in conjunction with accompanying drawing.Be to be noted that described embodiment only is intended to be convenient to the understanding of the present invention, and it is not played any qualification effect.
As shown in Figure 1, the system that has a ultrasonic diagnostic equipment of Fingerprint Identification Unit forms and to comprise: transducer (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, 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 be embedded device or the microcomputer that has operating system; 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; Fingerprint Identification Unit can use very sophisticated in the market product, is connected on the controller by multiple interfaces.Although clearly do not indicate among the figure, the Fingerprint Identification Unit of mentioning here also can directly be embedded on the keyboard, and is mutual by the Interface and Controler of keyboard again.The main purpose of Fingerprint Identification Unit is that patient is carried out identity identification, thereby information such as patient's passing inspection data and medical history reliably, are correctly organized together, and makes things convenient for doctor's diagnosis.
Mostly provide preset value (Presets) that various imaging parameters are pre-seted on the present ultrasonic diagnostic equipment, Fig. 2 has provided the imaging parameters commonly used that is comprised in the cover 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, realizes that therefore the relevant preset value relevant with the doctor of patient is very necessary.
For the preset value of realizing that patient is correlated with, each patient information all must have the set of the preset value of a cover oneself so, as shown in Figure 3, the preset value set that certain given patient information is had is according to check point taxonomic organization, each check point can have the different preset value of many covers, such as check point 1 M is arranged
1The cover preset value is respectively preset value 1～preset value M
1The tricks of the preset value of each check point can be different, and the tricks of the preset value that check point n (1≤n≤N, N are the number of check point altogether) is had is M
n(M
n〉=0).(1≤n≤N) is with set (preset value 1～preset value M of its corresponding all preset value for check point n
n) be called check point n corresponding preset value table, if M
n=0, just we can say that check point n corresponding preset value table is for empty.In addition, because comprise a lot of parameters,, use " check point n. preset value i. parameter j " such contraction to refer to j parameter in the i cover preset value among the check point n here for the convenience of follow-up narration once the cover preset value.
Equally, for the preset value of realizing that the doctor is correlated with, each doctor must have the set of the preset value of a cover oneself so, as shown in Figure 4, the preset value set that certain particular doctor had is also organized according to check point, each check point can have many cover preset values, at first is the preset value that system provides, and is the preset value that doctor oneself preserves then.What the preset value set of being correlated with patient was different is, the preset value set owner that the doctor is correlated with will reflect doctor individual's hobby, therefore each preset value all has a name, be convenient to the doctor and select to use which preset value, and the preset value set owner that patient is correlated with will reflect patient's individual variation, only preset value should be able to automatically be selected by system, and does not need doctor's interference.That is to say that it is explicit that doctor's preset value is selected, and the preset value that patient is correlated with selection being an implicit expression, carries out automatically, is fully transparent to the doctor.
Fig. 5 is having preset value selection that the realization patient is correlated with on the ultrasonic diagnostic equipment of Fingerprint Identification Unit and the flow chart of preserving, and these steps realize in controller that all step is as follows:
51: gather patient's finger print information;
52: with all patient's finger print information comparisons of storing among the data base;
53: whether find the fingerprint of coupling, if find then execution in step 54, otherwise execution in step 56;
54: the pairing patient information of match query fingerprint from the data base;
55: load the preset value set of this patient information, execution in step 58 then;
56: create a new patient information;
57: this patient information is generated the preset value set of a sky;
58: the doctor selects check point n;
59:, from the preset value set of patient information, obtain corresponding preset value table according to the check point n that selects;
510: whether the preset value table is empty, if be sky then execution in step 511, otherwise execution in step 512;
511: load with check point n corresponding preset value the preset value when system dispatches from the factory, execution in step 513 then;
512: from the preset value set of patient information, select and load only preset value;
513: use the preset value that loads to begin patient is checked;
514: inspection data and the preset value of preserving patient.
In step 51, patient is placed on the finger of oneself and gathers finger print information on the fingerprint capturer under doctor's prompting; In step 52, the finger print information that controller obtains gathering, and with the data base in all finger print information comparisons of patient in the past of storing; In step 53, the fingerprint that controller judges whether to find in the data base and the new fingerprint of gathering is complementary if find, then changes step 54 over to, otherwise changes step 56 over to; In step 54, controller can conclude that current patient had inspection record in the past, therefore inquiry and load this patient's information such as name, sex, ID from the data base; In step 55, the controller preset value set of inquiry and loading current patient information from the data base automatically changes step 58 then over to; In step 56, because the finger print information that in the data base, does not find the fingerprint with current patient to be complementary, therefore controller can conclude that current patient did not have inspection record in the past, therefore new patient information of system creation, and allow the doctor to import patient's information such as name, sex, ID by hand; In step 57, the preset value that current patient information is generated a sky is gathered, and that is to say that the pairing preset value table of all check points all is empty, changes step 58 then over to; In step 58, the doctor selects a suitable check point according to patient's situation, is designated as check point n; In step 59, the check point n that system is selected according to the doctor obtains corresponding preset value table from the preset value set of patient information; In step 510, system judges whether above-mentioned preset value table is empty, if be empty, then execution in step 511, otherwise execution in step 512; In step 511, because the preset value table is empty, show that concerning current patient current check point is to check first, also therefore the record of the preset value of in the past not preserving loads the default preset value that is provided with when system dispatches from the factory, and execution in step 513 then; In step 512, because the preset value table is not empty, show concerning current patient, current check point had had inspection record in the past, and there have been some suitable preset values to have used, therefore controller is selected from the preset value set of patient information and is loaded only preset value, and concrete selection and loading method can be made detailed description in conjunction with Fig. 6 in the back; In step 513, the doctor uses the preset value that loads automatically in the preceding step that patient is checked, here need to prove, the selection of the preset value of patient information and loading are that system finishes automatically, and the doctor does not need to do any operation, even also are unaware of these operations that the system backstage is done, only need be placed on energy in the inspection to patient and get final product, in addition, in checking process, the doctor still can regulate the parameter of some preset value as required; In step 514, the doctor selects the preservation on the keyboard or prints button, and patient's inspection data are preserved or printed, and at this moment, system preserves the value of parameters all in the current preset value automatically, and associates with current patient.The reason of so doing is when the doctor selects to preserve or prints a sub-picture, it is satisfied to the quality of this width of cloth image that he often is described, therefore current preset value can be represented current check patient's personal feature better, needs to preserve to get up to be provided with the back and uses.Preserve the process of the preset value that patient is correlated with, will provide in conjunction with Fig. 7 in the back and specify.At last, whole process finishes.
In step 512, only preset value be selected and be loaded to controller need from the preset value set of patient information, because with current check position corresponding preset value table the parameter value of many cover preset values may have been arranged in the set of the preset value of patient information, it is very important how therefrom selecting the parameter value of most representative preset value.Here use the method for statistics, the number of times that the value of each parameter occurs in whole preset value table in the calculating preset value, take out that maximum value of occurrence number then, as most representative parameter value, as shown in Figure 6, it is as follows to select and load the concrete steps of only preset value from patient information preset value set:
61: obtain check point n;
62: inquiry obtains with the corresponding preset value table of check point n;
63: generate a new preset value S, the number L of parameter is identical with the number of parameter in the existing preset value among the preset value S;
64: the length M of judging described preset value table
nWhether greater than 1, if greater than 1, execution in step 65, otherwise execution in step 616;
65: make i=1;
66: make j=1;
67: generate a length and be 256 one dimension integer array H, all elements are initialized as 0;
68: obtain in the described preset value table value of i parameter in j the preset value, be expressed as preset value j. parameter i;
69: the occurrence number of using array H to add up described preset value j. parameter i: search a preset value j. parameter i, then make the value of H (preset value j. parameter i) increase by 1;
610: make the value of j increase by 1;
611: judge that j is whether greater than the length M of described preset value table
nIf, greater than then execution in step 612, otherwise execution in step 68;
612: in array H, search Max, make H (Max) get maximum;
613: i the parameter assignment of giving new preset value S: preset value S. parameter i=Max;
614: make the value of i increase by 1;
615: judge i whether greater than the number L of parameter among the preset value S, if greater than execution in step 618, otherwise execution in step 66;
616: in described preset value table, obtain the first cover preset value;
617: make parameters all among the preset value S equal corresponding parameters in the described first cover preset value;
618: all parameters among the output preset value S.
In step 61, controller at first obtains current check point, in order to narrate conveniently, supposes that current check point is check point n (1≤n≤N); In step 62, controller inquiry in the preset value set of patient information obtains with the corresponding preset value table of check point n; In step 63, controller generates the new preset value S of a cover, and wherein the value of each parameter is composed an initial value, and this initial value can be arbitrary value, and the number of parameters that all preset values comprised all equates, is assumed to be L; In step 64, controller is judged the length M of preset value table
nGreater than 1, if greater than 1, then execution in step 65, otherwise execution in step 616; In step 65, because the length of preset value table is greater than 1, therefore the number of times that needs the value of each parameter of statistics in all preset values, to occur, here adopted dual circulation to realize, the index value of representing parameter in the preset value with i, represent the index value of preset value in the preset value table with j, at first give the i initialize, make it equal first parameter; In step 66, give the j initialize, make it equal the first cover preset value; In step 67, generate a length and be 256 one dimension integer array H, all elements are initialized as 0, and array H writes down the number of times that the different values of i parameter occur in the preset value table, also be called the statistics with histogram of parameter value; In step 68, from the preset value table, obtain the value of i parameter in the j cover preset value, note by abridging and be: preset value j. parameter i; In step 69, the occurrence number of statistics " preset value j. parameter i " this value can use array H to realize, makes the occurrence number increase of " preset value j. parameter i " this value get final product for 1 time.Here it should be noted that, the value of most of parameter should be a successive value, but on present ultrasonic diagnostic equipment, often these successive values are dispersed and turn to several class, regulate to make things convenient for the user, such as the value of " edge enhancing " this parameter, originally can be a successive floating number, but on the equipment of reality, can only regulate in 1,2,3,4 these discrete shelves often, this fact has also made things convenient for here the statistics to the parameter value occurrence number.All parameter range are represented with a byte all at 0-255, so the length of array H is 256.For the ease of understanding, here provide an example, suppose that i parameter is " edge enhancing ", its value is 3 in j cover preset value, then " preset value j. parameter i "=3 suppose that 3 these values have occurred 2 times, just H (3)=2, need increase by 1 to this number of times more so now, therefore carry out H (3)=H (3)+1=2+1=3; In step 610, make j point to next cover preset value; In step 611, controller judges whether to handle preset values all in the preset value table, if handle, then execution in step 612, otherwise fall back on step 68, continues circulation and carries out; Therefore in step 612, the value condition of i parameter complete reaction is searched Max in H in array H, makes the value maximum of H (Max), and the value of Max is exactly i the most representative value of parameter so; In step 613, the most representative value Max that finds is composed i parameter to the preset value S that generates in step 63: preset value S. parameter i=Max; In step 614, make i point to next parameter; In step 615, controller judges whether to handle all parameters, and wherein L represents the number of parameter in the preset value, if handle, then execution in step 618, otherwise fall back on step 66, continues the next parameter of circular treatment; In step 616, because the length of preset value table is smaller or equal to 1, can know that from the step 510 of Fig. 5 the preset value table is not sky in addition, therefore can know and have only a cover preset value in the preset value table, only need the directly loading first cover preset value (brief note is preset value 1) to get final product; In step 617, make all parameters of the preset value S that generates in the step 63 all equal corresponding parameters in the preset value 1, execution in step 618 then; In step 618, output preset value S selects as the preset value of current patient the best.
In step 514, when the doctor selected the preservation on the keyboard or prints button, controller needed to preserve automatically all parameters in the current preset value, and associated with current patient information, as the part in the preset value set of this patient information.As shown in Figure 7, the concrete steps of preservation patient information preset value are as follows:
71: the value that reads all parameters in the currently used preset value;
72: generate a new preset value S1;
73: make all parameters among the new preset value S1 equal the value of corresponding parameter in the current preset value;
74: obtain current check point n;
75: inquiry obtains with the corresponding preset value table of current check position n;
76: make in the preset value table existing preset value one by one with preset value S1 relatively;
77: judge whether to exist with preset value S1 in all identical preset values of parameter, if exist then execution in step 79, otherwise execution in step 78;
78: preset value S1 is appended the end that is saved in the preset value table;
79: the inspection data of preserving patient.
In step 71, controller at first reads the value of all parameters in the preset value of the current usefulness of doctor, and the value of these parameters has been represented the once successful Image Acquisition to current patient, and therefore the representative meaning is relatively arranged; In step 72, controller generates a new preset value S1; In step 73, make parameters all among the preset value S1 equal the value of corresponding parameter in the current preset value; In step 74, obtain current check point n; In step 75, inquiry obtains with the corresponding preset value table of current check position n from the preset value set of patient information; In step 76, controller will guarantee that the current preset value that will preserve can not be identical with the preset value that has existed in the preset value table, therefore to make in the preset value table existing preset value one by one with preset value S1 relatively; In step 77, controller judge in the preset value table, whether exist with preset value S1 in all identical preset values of parameter, if exist, then execution in step 79, otherwise execution in step 78; In step 78, controller appends the end that is saved in the preset value table with new preset value S1, thereby as the part of the preset value of current patient information set; In step 79, controller is saved in patient's inspection data among the data base.
As shown in Figure 8, have and realize on the ultrasonic diagnostic equipment of Fingerprint Identification Unit that preset value that the doctor is correlated with is selected and the concrete steps of preserving are as follows, these steps all realize in controller.
81: gather doctor's finger print information;
82: with all doctor's finger print information comparisons of storing among the data base;
83: whether find the fingerprint of coupling, if find then execution in step 84, otherwise execution in step 85;
84: the preset value set that the doctor of loading coupling fingerprint correspondence is correlated with, execution in step 86 then;
85: load the default preset value set of installing when diasonograph dispatches from the factory;
86: the check point grouping is pressed in the preset value set that loads arrange, be shown to the doctor;
87: the doctor selects check point n1 and preset value;
88: begin to check;
89: the doctor regulates the parameter of preset value and selects to preserve;
810: doctor's preset value title of preset value input for preserving;
811: in the preset value set that the doctor is correlated with, obtain with the corresponding preset value table of described check point n1;
812: will select all parameter values of the preset value preserved and the preset value title of doctor's input to append the end that is saved in described preset value table.
In step 81, doctor oneself gathers the finger print information of oneself on Fingerprint Identification Unit; In step 82, the finger print information that controller obtains gathering, and with the data base in all doctors' of storing finger print information comparison, because use the doctor's of this ultrasonic diagnostic equipment number to be far smaller than patient's number certainly, therefore in order to accelerate the speed of fingerprint comparison, in the system patient's finger print information and doctor's finger print information branch are deposited two data bases the insides; In step 83, the fingerprint that controller judges whether to find in doctor's finger print information data base and the new fingerprint of gathering is complementary if find, then changes step 84 over to, otherwise changes step 85 over to; In step 84, because found the fingerprint of coupling, illustrating so before the doctor of current use equipment has overwriting in system, so controller loads this doctor's preset value set automatically, and execution in step 86 then; In step 85, because do not find the fingerprint of coupling, the doctor that current use equipment is described so for the first time uses this equipment, so the default preset value that controller is provided with when moving loading equipment dispatches from the factory is gathered; In step 86, controller is arranged the preset value set that loads according to check point, be presented on the display, selects for the doctor; In step 87, the doctor selects a suitable check point (being designated as check point n1) and preset value according to patient's situation; In step 88, the doctor begins patient is checked; In step 89, the doctor regulates the parameter of some preset values according to the use habit of oneself, if feel satisfied, can select to preserve, and this moment, controller can show on display that is preserved a dialog box; In step 810, the name of doctor's input preset value in preserving dialog box, this name has been come according to the personal like, when same doctor uses equipment next time, sees that this name just can know that this overlaps preset value and is applicable to what purpose; In step 811, controller inquiry from the set of doctor's preset value obtains with the corresponding preset value table of check point n1; In step 812, controller reads the value of parameters all in the preset value of current use and the name of the preset value that the doctor imports, append the end that is saved in doctor's preset value table, in addition, between set of doctor's preset value and doctor's finger print information, set up relatedly, use during in order to next fingerprint matching.At last, whole process finishes.
