Description

Measurement protocol optimization for medical skill device

Technical field

The present invention relates to data process and field of medical technology, and the device of particularly imaging device, Such as MRT device.

Background technology

In using imaging device to check, such as use MRT device (MRT), Computed tomographic apparatus (CT), positron emission tomography device (PET) or other core doctor During treatment device checks, there is following necessity in clinical practice, the agreement ginseng of agreement will be measured Number is flux matched with value and other inspection specific to patient.It is thus possible, for instance the measurement agreement that must will determine Parameter is mated with each vital capacity or the EKG value of patient.These values are different according to situation difference, and Generally only just it is recorded before being respectively checked or measured.

In clinical practice, multiple predefined measurement agreement has the most been summarized as useful Measure agreement.But, if mated manual with specific amount and value for these predefined measurement agreements, Known method the most in the prior art may adversely find, the most unfortunately find suboptimal Agreement adjusts, and this causes lower picture quality and ultimately results in the diagnostic value of reduction.

Depending on type and other clinical and/or medical treatment amounts of checked organ, agreement is measured in definition Different protocol parameters.The example of such protocol parameter is following amount: TE-echo time, TR -the repetition time, FOV-visual field, layer thickness/slice thickness, etc..

For optimizing the determination measuring protocol parameter, well known in the art provide for automatization MR The method measuring sequence.For checking knee joint, check that automatic MR measures sequence the most under study for action raw Become (see F.E.Lecouvet et al., " Clinical Evaluation ofAutomated Scan Prescription Of Knee MR Images " in:Journal of Magnetic Resonance Imaging 29:141-145 (2009)).Other clinical researches are also dedicated to MR and measure automatically generating of agreement, it may be assumed that T.Benner et Al., " Comparison of Manual and Automatic Section Positioning of Brain MR Images " in: " Radiology ": Vol.239:No.1-April 2006 and K.L.Weiss et al., " Automated Spine Survey Iterative Scan Technique " in: " Radiology ", Vol.239: No.1-April 2006。

Jointly suggested one for other method aforementioned that mention in detail and from prior art can It is used for automatically generating the method measuring agreement.

But, show that this has obvious shortcoming, in terms of i.e. the method does not provides user in practice Configuration possibility.But distribute predetermined value for user.Due to clinical and/or medical, Need repeatedly to mate existing protocol and actual value.

This problem solves in the known method of prior art in the following way, i.e. MR scanning device each Operator first determine data specific to patient (such as, vital capacity (Lufthaltevolumen), Patient height, patient position on platform, the rhythm of the heart etc. of patient).Then, operator are from a large amount of MR Agreement select he think most suitable MR agreement.In a subsequent step, operator must be then Measure, according to patient, the protocol parameter that will determine, such as acquisition time (acquisition time), with specific to The value (such as vital capacity) of patient or carry out manual coupling according to the visual field of the height of patient.The method quilt Prove time consuming and be particularly easy to make a mistake, because due to manual impact, so the wind of mistake input Danger raises.

Need at this it is considered that the determination often multidimensional suitably measuring agreement with each protocol parameter is asked Topic.This determination based on following situation, i.e. protocol parameter is the most interrelated.In other words, The selection of one protocol parameter can affect the determination of other protocol parameters.

Summary of the invention

Therefore the technical problem to be solved in the present invention is, proposes a kind of life improved and simplify measurement agreement The method become.Especially, the determination process of single protocol parameter should be optimized, and should be user and provide pass In condition to be determined and the configuration possibility of rule.

Above-mentioned technical problem is joined especially by the agreement of a kind of measurement agreement for optimizing measurement equipment The method of number, and solved by the system of a kind of computer supported, described method can also be configured to meter Calculation machine program or hardware are implemented.

Hereinafter according to the solution in terms of method, the present invention will be described.Advantage, spy referred in this Point and alternate embodiments are also applied for other claim categories, such as system, or vice versa.Method Each functional character wherein implements each functional module at this corresponding to system or computer product.Mould Block can be software and/or hardware module.

One aspect of the present invention therefore relates to a kind of measurement agreement for optimizing medical equipment The computer-implemented method of protocol parameter, is wherein measured agreement and is determined by protocol parameter, described method Comprise the steps:

-it is configured to determine at least one condition of the physical parameter of protocol parameter；

-it being configured to determine at least one rule of protocol parameter, wherein said rule definition is for difference The regulation (Vorgaben) of physical parameter；

-depend on the physical values of applied record, computer supported ground Automatic Optimal protocol parameter, its In at least one condition, rule and physical values can change with being independent of each other.

It is considered herein that arrive, it is to be checked right that biophysics value is recorded by additional additionally measuring and is not related to As (organ).Biophysics value includes that vital capacity, EKG measure and/or heart signal.These biological things Reason value is not related to the geometry variable of the object that medical equipment to be used checks, such as, be not related to object Size.Biophysics value is the most full decoupled and unrelated with object to be checked (it is therefoie, for example, vital capacity Or the rhythm of the heart is unrelated with object to be checked " liver ").In a preferred embodiment of the invention, biological thing Reason value includes vital capacity (therefore, the breath holding time of patient).

Hereinafter will be explained in detail the ultimate principle used in this patent application.

Concept " optimize " or " being optimized " the most broadly understand and usually relate to automatically or The calculating of computer supported.Optimize this according to optimisation criteria to calculate.The critical aspects of the present invention is, excellent Change standard is configurable.Especially, optimisation criteria can be mated by user or configure.User can lead to Cross configuration condition and/or rule is determined in advance optimisation criteria, but also can determine optimisation criteria during measuring. It is thus possible, for instance user can determine that certain priority, according to described priority, a protocol parameter ratio Another protocol parameter is more important.In principle, it is possible to be the optimization of already present protocol parameter.Can also , first time and the most newly determined protocol parameter.

In a preferred embodiment, the present invention is designed as optimizing the measurement agreement for MR equipment Protocol parameter.But, also provide for other medical equipments in this alternative embodiment Measure agreement, such as PET, CT and/or other radiology devices.

" configure " and mean to provide the change probability in terms of user or adjust probability or coupling may Property.According to the main aspect of the present invention, should be user provides and affects protocol parameter and determine and the most generally The probability of agreement is measured in impact, without the advantage abandoning automatic pre-configured measurement agreement.In other words, Therefore user should perform specific to patient's and therefore specific to the adjustment of situation, and described adjustment affects Measure agreement.Preferably, user obtains system support when configuring (condition and/or rule).This Generally by providing screen form (Bildschirmmaske) and/or previously given menu to carry out, make User's thus optional menu option determined.This is prone to clearly operate the method according to the invention significantly Or system.

According to an aspect of the present invention, can configure or determine at least one " condition ".Here, one Condition relates separately to a protocol parameter.Condition can be defined by user or configure.Favourable in the present invention Embodiment in, condition also can be combined by Boolean condition, the most as follows combination: condition A With condition B or non-(condition C).Substantially, condition relate separately to can not measure preparatory stage from The physical parameter defined dynamicly.Physical parameter such as relates to the parameter relevant to patient or specific to measurement Parameter and/or the parameter specific to equipment, the most usually relate to cannot be determined beforehand specific to situation Parameter.

According to preferred embodiment, additionally or alternatively can also be configured " regular ".But this is optional Feature, thus also can not configuration rule or only configuration one rule.Additionally, the replacement in the present invention is real Execute in mode the most meaningfully, only configure at least one rule and not configuration condition.Described rule relates to This determine: " if<condition>, then<behavior>" or " when<condition>meet/is unsatisfactory for, then perform <behavior>".Generally, can be by multiple conditional combinations, the most as follows: " if value W1 is at a extremely If in the range of d and be worth W2 below threshold value S1, then protocol parameter P1:=X ".Therefore, make User can use rule to determine, should implement which behavior about protocol parameter in defined conditions (Aktion), its conditional relates to (such as, measuring and/or read in of the record relevant to physical parameter ) value, and wherein action relates to protocol parameter.

It is thus provided that duplex configuration probability.

Which physical parameter is defined, it is proposed, according to the invention, in side subsequently according in condition and/or rule In method step-perform described method step-measure and/or read in each physical values the most before measuring. It is to be noted that at this concept " parameter " and " value " are interpreted as common mathematical meaning.Here, ginseng The concept of number is interpreted as variable or asterisk wildcard (Platzhalter), and the physical record that value is each parameter (is surveyed Amount or read in) amount.Such as, the concrete value of parameter " Patient height " can be saying of " 1.85 " Bright；The physical values of parameter " visual field-FOV " can be such as the explanation of " 220-240 ".Concrete Physical values is not determined in advance, and depends on each medical conditions.Described physical values is likely to be dependent on patient, Depend on the type checked, depend on the time period checked, depend on checking mode, depend on scrutineer Member and/or depend on other amounts.According to the invention provides the different modes how recording physical values.Excellent Selection of land, carries out the measurement (this can directly be carried out before MR checks, or carries out) being worth in the time earlier, And/or also can read in physical values by corresponding interface.Such as it is possible that, physical values is examined from advance Look into it is known that and need not again and the most repeatedly measure.In addition it is also possible that be manually entered thing Reason value, such as, by examiner or even directly inputted by patient.For professional, obvious except aforementioned Outside the probability automatically or manually recording physical values mentioned, there is also other notes within the scope of the invention Record pattern.

Within the scope of the invention, distinguish on the one hand " protocol parameter " on the other hand " physical parameter ". First concept " protocol parameter " relate to measurement agreement to be optimized parameter (such as, TR, TE, cut Sheet thickness, etc.), and the second concept relates to specific to position and contextual parameter, it relates to system Physics or the amount of technology and impact with measurement agreement (such as, organ size, the trouble of its protocol parameter Person's height, patient position etc.).

As long as have recorded the concrete physical values about relevant physical parameter, then can apply the thing with record The condition of the configuration of reason value and/or the value of configuration.In mathematical meaning, this process is corresponding to by concrete Measured value is updated in the equation with variable.Therefore, this relates to performing fully automatically to be implemented by computer Calculating process.In " application ", therefore check which condition and/or rule meet concrete note now The physical values of record, and which condition and/or rule are unsatisfactory for.Therefore configured behavior or order are performed. This relates to the determination of protocol parameter.

In last step, therefore can according to the configured rule of the physical values for physical record and/ Or condition, (i.e. calculating) target protocol parameter of current actual agreements parameter with optimization is carried out excellent Change.Advantageously, this optimization is fully automatically carried out.In other words, it is not necessary to other user input.For This provides the access for existing protocol data set.But, advise in the advantageous extension of the present invention, When performing the measurement protocol sequence optimized, it is desirable to confirmed by user.This be for improve safety and Avoid the undesirable covering for measuring protocol sequence.However, it is possible to preset so that only existing Some measurement agreements just require that user confirms when being the most modified or optimized.

Advise according to other aspects of the invention, can simulate and calculate the dependency between protocol parameter.This Can be by being realized by user correspondingly configuration condition and/or rule.Therefore, can pass through especially The configuration of rule, depends on the determination of other protocol parameters, defines the determination of the first protocol parameter.If Should depend on that previous protocol parameter determines other protocol parameters, then when this is to determine different protocol parameters Chronological order premised on.Also by configuring corresponding rule, other dependencys can be described.Such as, it is possible to The regulation of other parameters is depended in configuration, such as, depend on executed checking in advance, parallel check or not The inspection planned.

According to another aspect of the present invention, the physical values of (such as can be measured and/or reading) record It is that patient is correlated with, biophysics and/or specific to the value measured.Described value substantially can be by connecing Mouth is automatically read, (such as from radiology information system-RIS system, or from image storage and transmission system System-PACS system reads in).Additionally, described value also can be manually entered by the user interface having been provided that. Preferably, the record of value or input and reading in directly is carried out before measuring.Alternatively, it is also possible in standard Standby stage record value.Parallel and it may be said that simultaneously record value can also be checked similarly with MR.Example As, when must record EKG signal or heart signal to determine protocol parameter during MR checks, this Point is required.Except patient be correlated with, biophysics or in addition to measuring relevant value, value can also refer to it His physical descriptor and/or device-dependent variable.Due to the multiformity of parameter to be configured, so according to this Invention can be advantageously carried out high transmutability and motility in optimization.

Advise according to another aspect of the present invention, in the rule that the physical values recorded is applied to configuration And/or configuration condition time analyze, which configuration condition and/or which configuration rule for each note The physical values of record is satisfied, and which is ungratified.Thereby determine that and which should perform about protocol parameter A little behaviors.In a preferred embodiment, concept " behavior " relates to concrete measurement protocol parameter Select, and therefore relate to its determination optimized.

Preferably, configuration and/or the configuration of at least one condition of rule is carried out by the user of system. Thus, the configuration that user is personalized can be carried out.Therefore, optimization process can carry out spy according to applicable cases Fixed design.If but it can be possible that without specific to the coupling of situation and optimization, then according in advance The workflow of definition performs configuration.

The present invention preferred embodiment in, method can divide into two time periods: on the one hand provides Configuration phase, is on the other hand the preparatory stage for preparing actual measurement.Typically, the two rank Section is independent of each other so that the preparatory stage can (and with configuration phase independently) start at any time.But After configuration phase terminates, generally perform the preparatory stage to prepare to measure.But it can be possible that two time rank Section is overlapping.At configuration phase, (on the one hand at least one condition, and the opposing party generally carrying out configuring At least one rule of face) method step.In the preparatory stage, will record (measure and/or read in) Physical values is applied to configured rule and/or condition, and carries out the Automatic Optimal of protocol parameter.Substitute Ground, it is also possible to be only to perform the optimization of protocol parameter in the preparatory stage, and applying step still with configuration rank Duan Xiangguan.

The key feature of the solution according to the present invention is the configuration possibility in terms of user, described in join Put probability need not to be specific to patient's and also can perform during measuring the formulation of agreement.Can also It is if user starts optimization program, then to optimize process and also can measure the phase at the MR of actual motion Between perform.If optimization program causes current protocol parameter should be substituted, then by the protocol parameter optimized This also can online and it may be said that determined by corresponding user during measurement process and perform.Therefore (on-the-fly-Optimierung) is optimized in can performing to run.

Advising in a preferred embodiment of the invention, user can be from proposed a large amount of physical parameters Select the physical parameter relevant for its each applicable cases.In other words, method can include other steps:

The physical parameter that-selection is correlated with, then (subsequently) can be to described association for determining protocol parameter View parameter configuration condition and/or regular and record value.

Therefore, by being only primarily upon the physical parameter being correlated with, advantageously, optimization can be more efficiently carried out Method.It is thus possible, for instance in the shortest and less complex MR measures, if such as knee should be checked, The most do not require to record the such as heart beating of patient, vital capacity, the physical parameter of blood values etc..Therefore, can contract Short optimization process and application person are without going through clicking on the menu relating to uncorrelated parameter.

According to other aspects, optimization method is by the optimization module preferably run on MR scanning device (for example, it may be software module or hardware module) performs.Optimize other dresses of module and radiology system Put integration, such as with image reconstruction computer, memorizer (especially for protocol data group and specific to The memorizer of the data of agreement), information system etc. integrates.

Configuration is preferably performed by the user interface provided.Here, generation script and then explanation should Script and perform this script optimizing in module.Here, preferably can store configured rule and/or Configured condition, so that these adjust the optimization process that can also be used for subsequently.

In complicated medical conditions, it may be necessary to make certain rule and/or certain condition only by Step and can be configured the most under certain conditions.Such as, the configuration of rule and/or condition can Depend on the record of physical values.Additionally, configuration also can be depending on previous configuration.For also including that this applies Situation, in other embodiments of the present invention, suggestion is iteratively applied optimization method.

Obvious advantage is that of solution according to the present invention, each application person has different configurations Probability so that application person A available configuration a, and other application person B may utilize as joining that it customizes Put b.Therefore each application person may utilize and works for its protocol optimization customized.In addition, it is possible to describe or Consider during optimizing individually specific to the requirement of user.Difference can be set by configuration possibility Priority so that can be such as resolution give than signal to noise ratio, there is higher priority.

Other major advantages of the present invention also reside in, and can fully automatically perform the optimization of agreement.Additionally, only Configuration to be performed, the most also i.e. can perform optimization at runtime during MR checks.Therefore, also So that configuration (is i.e. stored preferably in configuration memorizer, according to quilt in the optimization of the present invention The configuration performed, such as rule, condition, regulation, described configuration) checking for different MR can be many Secondary use.When performing medical examination or adjusting each equipment, which results in obvious efficiency and improve.

Other advantages lie also in, and number of protocols to be generated can obviously reduce, because being no longer necessary to for often Individual applicable cases generates different configurations.Same configuration can be automatically matched to different applicable cases, and Also the different situations specific to patient is matched.

Also being certified as advantageously, the time span performing to check can obviously reduce, because optimizing is can Automatically performing, this accelerates workflow generally.

Other advantages are the picture quality improved.By full automatic protocol optimization or coupling, can avoid by The mistake caused is manually entered in wrong.The optimization process improved also helps to undesirable for this Image effect, such as motion artifacts or non-optimal picture contrast.The configuration different by offer may Property, can in the higher level's aspect in rank coupling change strategy ( At this Automatically each coupling is performed.

Optimization process is from performing.The system that this means automatically detects configured condition and/or has joined Whether the rule put meets the physical values of record (measure or read in), and should perform agreement ginseng the most subsequently The change of number.If needing to change, then this changes execution automatically.If need not change, the most exist Optimum measurement agreement；Otherwise, current by optimizing (specified) parameter replacement (actual) parameter.

Other solutions of aforesaid the technical problem to be solved in the present invention are, are using medical skill When equipment (preferably MR equipment) performs medical examination, use the optimization side hereinbefore described in detail Method.During performing MR measurement, optimizing measurement agreement at runtime according to optimization method, method is, If desired for then replacing current actual agreements parameter by the target protocol parameter of the optimization of calculating.

Other solution is the optimization system of the computer supported according to attached claims.Excellent Change system preferably includes configuration module, logging modle and computing module.Module also can be as separate portion Part is connected on MR scanning device by corresponding interface.Module can also be embodied directly in MR scanning In device.Module can also be provided as computer program and use, described computer program can Recalled from server by network interface.It can be possible that modules is also embodied in different On armarium so that the single interface of preceding method or the single module of system are as vendible Unit, and remaining interface or module can perform in other unit.

Method is also configured as computer program, if wherein by the alternate embodiments suggestion of the present invention Computer program performs at computer or on the processor relevant to computer, then cause computer to perform Method described in detail above.The solution substituted lies also in storage medium, and described storage medium is used for Store the method for aforementioned computer enforcement and by embodied on computer readable.

Detailed description of the invention

Hereinafter describing the present invention according to embodiment, described embodiment relates to field of medical technology, especially Ground relates to radiology field.Other application possibilities are to optimize CT measurement agreement, US measures agreement, PET measures agreement or other measure agreement.

Fig. 1 has gone out the behavior and its each result performed according to the present invention with indicative icon.At end (shown on the right side of Fig. 1) obtains or outputs one group of protocol parameter optimized.For that purpose it is necessary to thing First carry out a series of adjustment illustrated in FIG.Here, if desired for still can order of the steps may be varied.Root According to preferred embodiment advising, first determine in preparation process and phase is checked for present case or MR The physical parameter closed.Then, for the physical parameter configuration condition selected.This condition can relate to region and says Bright (Bereichsangaben) and the comparison of threshold value and standard value or the comparison of other reference values.Bar Part can with the form of " if->, ", or equivalently with " when ...-> then perform " form implement. If the optimization task of complexity, then except the configuration of condition, also can additionally provide other configurations possible Property；But described configuration possibility be not compulsive requirement and be only optional.Other configuration possibilitys described Relate to the configuration of rule.Generally, multiple conditions can be combined the most as follows: " if value W1 Region [a ..., d] in, and value W2 drops to below for the threshold value of standard value S1, then set agreement and join Number P1:=X ".This rule therefore relates to two physical values or relates to two parameters W1 and W2.For specially Industry personnel are obvious, any combination between each condition of this definable.In addition, it is possible to be combined with each other rule Then.This configuration possibility not provided in the current method of prior art is provided, can automatically carry out and bright Aobvious simplification protocol optimization, this is by always repeatedly inputting optimisation criteria but for this definable in agreement Automatically the rule applied during optimization realizes.

Additionally, can for applicable cases define priority, and such as can process compared with other parameters with The physical parameter of the determination of higher priority.Dependency between the determination of protocol parameter also can be described.

Dependency when determining or optimize protocol parameter is explained in following example.Such as, if should hold The wherein patient that goes must hold one's breath not make the axially measured (such as, with VIBE of the liver of scalloping Order), then draft (aufsetzen) and cover 72 tomographies of the tomography thickness being respectively provided with 3mm Typically measure agreement.Use these protocol parameters to adjust be completely covered and can hold one's breath 20 seconds patient Period measurement standard liver.If but this physical parameter can not be met, such as because patient is only capable of holding one's breath Shorter time (such as, 15 seconds) and/or the liver because of patient are exaggerated, then must select other Protocol parameter.Therefore, optimization is necessary, because bigger covering is necessary.The quantity of tomography must Such as must rise to 80 from 72.Further, it is necessary to carry out the coupling of physical parameter, in order to such as will Data set " PhasePartialFourier " changes into 6/8 from 8/8, again to obtain within the following time period The measurement time, within this time period, patient can hold one's breath (being 15 seconds in previous example).This example because of This explains, physical parameter (size of the parameter being correlated with for patient at this, such as liver, hold one's breath time Between length etc.) change also make the optimization of protocol parameter become required.

Further, it is also possible to, the amendment of a protocol parameter, mate or optimize and also cause other agreements The change of parameter.This iteration of method perform in FIG by sending from result, i.e. from the association optimized The group of view parameter is set out and points to left side and arrow diagramming that therefore pointing method starts.

In example mentioned above, the physical parameter selected is:

1. breath holding time length, and

2. liver size

By condition and the configuration of rule, can be depending on the quantity of the tomography that aforementioned parameters definition needs with each Tomography thickness.

So far the method step needed for the moment, i.e. selects physical parameter, configures the bar for this physical parameter Part and configuration, for the rule of physical parameter, can perform in any time before inspection in advance.This generally exists Configuration phase performs, and described configuration phase substantially can be measured with the MR that reality performs and perform independently, And carry out before it.In FIG, another step is relevant to configuration phase.This relate to measure for The physical values of the physical parameter selected.This step the most necessarily performs at configuration phase, but also can be direct Carry out before measuring, and also the most relevant to the preparatory stage.

Illustrate which result the method step of diagram in first row has the most in a second column. Therefore, the selection of physical parameter causes a parameter group, and the configuration of condition causes a condition group, rule Configuration cause a rule sets, and the measurement relating to the physical values of selected physical parameter causes one group Value.They are optionally stored in separate file, thus also can change them with being independent of each other.Additionally, In another embodiment, outside example (instanz) also may have access to this data set or file.Only Parameter group to be defined, condition group, then configuration phase can terminate.Then can be complete in any moment subsequently Automatically carrying out actual optimization, this occurrence relating to physical parameter by measurement is carried out.Concept " is surveyed Amount " it is to be understood as included within this in meaning of " record ".Therefore, it is noted that by additional Additionally measure (such as by MR scanning device self, or by other equipment, such as EKG, blood pressure Equipment etc.) record described value.It can be possible that read in from the unit of other computer supporteds by interface Described value.If patient has been examined once, the most such as can be by Patient height and weight in patients from other The memorizer of module (RIS, PACS etc.) recalls or reads in.It is of course also possible to, application person and / or patient manually enter the input of the determination about value at this.

After have recorded value, this value can be applied to configured condition and/or configured rule. Herein it is again noted that the configuration of rule needs the most forcibly.The configuration of rule is only for wherein The complicated optimization situation that such as should define priority provides.Simple optimization task is only carried out joining of condition Put.

Shown in arranging the 3rd in FIG, will record (measure, manually enter or otherwise record) Value be applied to configured condition and/or rule.This application causes defined in condition and/or rule Protocol parameter may be changed.Then in each applicable cases (with concrete physical values, described physical values It may be said that " use " is in configured condition and/or rule) the middle protocol parameter optimizing change.

But, the present invention not only can be only used as pure software solution and be implemented in computer program, and And hardware can be provided to implement.Here, the system of computer supported includes configuring module K, described configuration mould Block K is designed as configuring at least one condition for the physical parameter selected, and the most selectively can set It is calculated as configuring at least one rule.Additionally, system includes logging modle E, described logging modle E It is designed as measuring and/or reading in and/or manually enter the physical values relating to selected physical parameter.Record Module E can arrange any logging mode, and performs automatically and manually record.Additionally, system includes meter Calculating module B, described computing module B is designed as being applied to the physical values recorded by logging modle E The rule of configuration and/or configured condition.Additionally, computing module B is designed as assisting for Automatic Optimal View parameter.Here, carry out according to the physical values of the record applied in configured rule and/or condition Optimize.

Configuration module K and logging modle E is depicted in fig. 2 in left side.From module at Fig. 2 Middle finger arrow to the right should marked the result of each module.Therefore, in configuration module K, have selected phase The physical parameter closed.Additionally, be configured with for (selected) physical parameter in configuration module K Condition.The rule for (selected) physical parameter is also provided in configuration module K.Relate to And the occurrence of selected physical parameter can be recorded to logging modle E.Here, logging modle also may be used It is incorporated in MR scanning device, is i.e. incorporated in medical equipment.All aforementioned quantities (physical parameter, Value, condition, rule) it is supplied to computing module B as input quantity (Input).Computing module by based on Calculate or optimize protocol parameter.

In the advantageous extension of the present invention, computing module B may be designed as again with other add-on modules. These modules can be used for automatically eliminating mistake (such as, input error), or provides notice to user.

Illustrating flow chart in figure 3, described flow chart is explained in detail in the allusion quotation according to preferred implementation The flow process of type.Here, read in configuration in the first step.Here, only join in simple embodiment Put condition.Here, can only define again a condition.But multiple conditions are generally configured at this.Alternatively, Can additionally configuration rule, wherein rule definition is for the regulation of different physical parameters.

Check that whether this is the final step of method.If it is not, then read in current agreement and record thing Reason parameter.This step includes selecting relevant physical parameter and record (by measuring and/or by reading in) Relate to the concrete physical values of physical parameter.

Check in a subsequent step, if all values and/or parameter detect the most.If it is not, then Check whether that all conditions is the most detected.If certainly, then checking whether that strictly all rules is the most tested Survey.If certainly, then jumping to next instruction.

If not all conditions or not strictly all rules the most detected, then check whether changing in agreement Become and still can carry out.If no longer can be changed, the most also jump to next instruction.If still can change Become, then perform automatically changing or optimizing of agreement.

After detecting all regulations, check whether and be successfully applied to strictly all rules, condition and miscellaneous stipulations. If can to this certainly, then method terminates.Otherwise, check whether and still can be changed in agreement, and Carry out as explained above.

Then other information of the configuration possibility of the condition of relating to should be again given.Definable one in condition The limit that fixed protocol parameter has to comply with.

Rule determines, with which protocol parameter of which kind of order modification.Preferably, MR agreement is being performed certainly During body, protocol changes or protocol optimization are blocked and therefore can not be carried out.But, because this due to (less than 0.5 second) is there is soon, so application person is the most not for optimizing the algorithm of the optimization of process The long waiting time must be considered.Rule such as can be as follows:

If " [condition] is unsatisfactory for, then with the step-size change of [value] (new settings, improve, reduce) [association View parameter] until [value] ".

In the MR of patient's liver checks, it usually needs carry out relative complex agreement operation, in order to energy Enough adjustment adjusting optimum about current patents position, Patient height and/or the vital capacity about patient. Generally draft previously given MR agreement at this, described agreement is optimised according to the present invention.First will be disconnected Layer location and subsequently observation have the image of acceptable signal-to-interference ratio (signal and the ratio-SNR of noise) Cross section (visual field-FOV).For each patient, final optimization pass acquisition time length, optimal to produce Picture quality.

In aforementioned exemplary, each adjust (FOV that such as, relates to, SNR, organ size etc.) also Can have certain tolerance value.

In cardiology checks, the most described acquisition time length is depending on vital capacity.Especially, Acquisition time length is necessarily less than vital capacity, so as to ensure enough picture quality.Here, gather Time span the most additionally depends on other parameters, such as, depend on organ size, and examine at cardiology Depend in looking into that (RR here means that the starting to each of Electrocardiographic QRS complex to RR gap length Time interval between next QRS complex), it affects phase encoding step (Phasenendcodierungsschritte).In this case, it is therefore necessary to the rule that configuration is complicated, with Just it is contemplated that dependency between protocol parameter.

It is finally pointed out that the description of the present invention and embodiment is interpreted as being not limited in principle the present invention Certain physics realization.For professional especially it is evident that the present invention can be partially or completely Ground software and/or hardware and/or multiple physical product-at this be the most also computer program- Interior distribution ground realizes.
