Embodiment

For making the object of the invention, technical scheme and advantage clearer, below lift embodiment the present invention is further explained.

Below be example with the CT scan, specify MOI of the present invention.How this carries out for the user who makes the user, especially lacks experience can learn current scanning, and the present invention provides a kind of real-time CT scan MOI, instructs thereby make the user obtain effective, vivid scanning.

Fig. 1 is an embodiment synoptic diagram of MOI of the present invention.Comprise the steps:

Step 101, before carrying out CT examination, the CT system at first is written into a scan protocols.Which kind of CT examination this scan protocols is for example made, how to be carried out this CT examination for patient.

Step 102, whether the input group of this scan protocols of CT systems inspection is also judged should the input group effective.

Each scan protocols has input group more than (entry group), just has when having only the input group of input group and CT systemic presupposition to coincide and instructs form to show.1. for example input group is the heart CT scan, and 2. the input group is Cranial Computed Tomography scanning, and preset input group is the heart CT scan, and 1. then input group is effectively, continues next step; 2. the input group then is invalid, and this moment, aphalangia guide window showed.

Step 103, system check successively whether the scanned items in effective input group instructs form.

Because each input group has an above scanned items (entry), each scanned items has respectively and instructs form accordingly, and these instruct form to be stored in the storer of CT system.So when carrying out like the heart CT scan, the CT system can check successively whether its each scanned items has and instruct form to show accordingly, if having, then from said storer, transfers out this and instructs form; If do not have, then continue the next scanned items of inspection.

The pairing form that instructs of different scanned items is different, and this is because the clinical meaning of different scanning item is distinguished.Eight scanned items when Fig. 2 has illustrated that the input group is the heart CT scan; Be location picture scanning, heart spiral scan, heart sequence scanning, time-out, monitoring in advance from top to bottom successively, add contrast preparation, monitoring and heart sequence scanning; Wherein the scanning of location picture instructs form for instructing form A; Heart spiral scan instruct form for instructing form B or instructing form C; The heart sequence scanning instruct form for instructing form D or instruct form E or instruct form I or instruct form J, pre-detection instruct form be instruct form F, add contrast preparation instruct form for instructing form G, monitoring instruct form for instructing form H.Be not that all scanned items all instruct form; For example suspend this scanned items and just do not instruct form, so when CT systems inspection during to this scanned items of time-out, owing to it does not instruct form; So show with regard to aphalangia guide window; Then to next scanned items---pre-detection is checked, because pre-detection instructs form, so carry out next step.

Step 104, when scanned items instructed form to show, the CT system instructed form to show to this.The user just can accomplish checked operation according to the form that instructs that shows successively like this.If the checked operation of user such as wherein one or more scanned items is very familiar certainly, also can close the form that instructs of demonstration at any time.

As shown in Figure 2, the CT systems inspection instructs form F to show to this scanned items of pre-detection, instructs form F so system shows, so that the user is according to instructing form F to accomplish the operating process of pre-detection.When scanned items instructed form to show, as adding contrast preparation, directly demonstration instructed form to get final product accordingly.

Further, said method also comprisesstep 105, if there is the said form that instructs, checks then whether said scanned items exists and the corresponding form that instructs of current scanning mode, if exist, shows that then this instructs form.

Like scanned items such as the heart spiral scan among Fig. 2, heart sequence scanning, monitoring in advance, monitorings; Because it has different scanning modes, whether the CT system needs the further current scanning mode of these scanned items of inspection, and judge and under current scanning mode, instruct form to show; If have; Show that then this instructs form, otherwise continue the next scanned items of inspection, until checking out all scanned items.Wherein current scanning mode comprise scan, scanning and scanning three kinds of states.Equally, with each instructs the corresponding scanning mode of form also to be stored in the aforementioned memory in these scanned items.

As picture scans in this scanned items in the location among Fig. 2; This scanned items of CT systems inspection is by instructing form; Because location picture scanning has different scanning modes, system needs the further current scanning mode of inspection location picture scanning, if scanning or scanning mode; System draws through judgement and scanning/and do not instruct form to show under the scanning mode, so aphalangia guide window shows; If the current scanning mode of CT systems inspection location picture scanning is scanning, and instruct form A to show under the scanning mode through judging not draw, so form A is instructed in demonstration, like this user just based on the location of instructing form A to accomplish heart as scanning process.Scanning or scanning mode do not instruct the reason of form to be, instruct form is to instruct the user before scanning, how to operate, when scanning or the end of scan shows that it is useless instructing form.This is explanation from another point of view also, and same scanned items is different at the form that instructs of difference inspection state, because the clinical meaning of same scanned items under difference inspection state is distinguishing.For example, in advance monitoring instructs form for instructing form F when scanning mode not, just scanning mode and scanning mode all do not instruct form.

In addition, it is different to be also shown in same scanned items residing position in whole scanning flow process among Fig. 2, instructs the form also can be different.As among the figure two scanned items being arranged all is the heart sequence scanning; One after the picture scanning of location; One after the notes tracking monitoring of (being divided into the stages such as preparatory monitoring, vein group notes, monitoring clinically); The difference of this position causes its clinical meaning also inequality, so doctor's focus is just different, need formulate corresponding form based on the clinical effect of this scanned items.Because the CT system checks successively whether scanned items exists to instruct form accordingly; When finding identical scanned items is arranged; Because the previous scanned items of this same scan item is different; So it is different that system can judge the form that instructs that this same scan item shows in different position, from the storer of form is instructed in storage, transfers the different forms that instructs in view of the above and show, correspondingly; Also further stored these in the storer and instructed the previous scanned items of form, instructed form accordingly to make things convenient for system to transfer exactly.Like the heart sequence scanning after location picture scanning, when scanning mode not,, just when scanning mode, do not instructing form for instructing form D, at scanning mode for instructing form E; Heart sequence scanning after monitoring for instructing form I, is not just instructing form when scanning mode when scanning mode not, during scanning mode for instructing form J, instruct form C here and instruct form J to instruct for next step image reconstruction.

Wherein instruct the content of form as shown in Figure 3; The synoptic diagram that instructs form A for this scanned items of location picture scanning among Fig. 2; For before carrying out heart location picture scanning, four operation stepss that the user need carry out, according to from top to bottom, from left to right order is respectively:

Sub-window 1: clinical guidance is used to make the user to know the degree that can assess coronary atherosclerosis through the calcium index;

Sub-window 2: put electrocardio (Electrocardiograph, ECG) electrode well;

Sub-window 3: sweep limit is set;

Sub-window 4: patient directions is exhaled with air-breathing.

Wherein sub-window is to instruct to indicate the user to carry out the step of checked operation in the form.

Visible when showing current sub-window among Fig. 3, current sub-window maximization, other sub-windows then minimize.Each sub-window comprises picture and/or literal, and its Chinese words is used for the concrete operations of this sub-window and/or effect are described, and picture is used for how operating to user signal, thus give user image, directly, the guidance that is easily understood.For example insub-window 2; Text prompt is: only after patient puts position (being that patient lies on the examination couch to check required correct body position), could place the ECG electrode; And whether inspection ECG signal normally shows; If the ECG electrode triggering on the card (Trigger card) appears dimmed, then can not scan; The picture ofsub-window 2 has then been illustrated the placement location of ECG electrode on human body.So user; Especially the user who lacks experience just can accomplish the operation of putting the ECG electrode well according to these tutorial messages (like literal and/or picture); And need not remove to consult user manual or ask experienced user to give some on the spot guidance, thereby practiced thrift the time, saved manpower.

On the other hand; The user can also revise the content that instructs form according to the experience/demand of oneself; As delete sub-window or increase new sub-window, and revise picture and/or the literal in the sub-window, and preserve the amended form that instructs; Thereby customization is fit to the form that instructs of oneself, has illustrated to instruct an editing interface of form like Fig. 4.When the user clicks among Fig. 3 the symbol of the approximate pencil in any upper right corner in four sub-windows, just got into the editing interface that instructs form, the literal in each sub-window can be edited and revise; Picture in each sub-window also can be revised, and for example imports exterior artwork, or the picture through catching certain orientation in the current screen with it as the signal picture.Five operating keys are arranged below Fig. 4, be followed successively by from left to right: interpolation step key, deletion step key, resuming default are provided with key, preserve key and ESC Escape.Wherein adding the step key is for current sub-window increases a sub-window, and as having illustrated an interface that increases new step among Fig. 4, so the step 3 among Fig. 3 has just become step 4 in Fig. 4, whole sub-window also correspondingly became for five steps.Deletion step key is used to delete current sub-window.Resuming default is provided with key, is used for the default setting of system that the sub-window that instructs form is reverted to, like sub-window, literal, the picture of default setting.Preserve key and be used to preserve the amended form that instructs, and the new form that instructs is stored in the said storer, as an original subsequent use form that instructs form, as having added new sub-window among preservation Fig. 4 and having revised the form that instructs of literal, picture.The user can customize the form that instructs that is fit to oneself and perhaps instruct form accordingly for one of scanned items establishment not instructing form so on the one hand; On the other hand; When afterwards other patients being carried out similar inspection, show that this instructs the condition of form, then can show this subsequent use form if meet; So experienced user just can be conducted experience to the user who lacks experience in this way, avoids the manpower consumption of on-the-spot guidance.

In sum; If the Rule of judgment instep 101～104 all meets; Then instruct form to show in real time, the user just can obtain instructing at once like this, and operates step by step according to this guidance in scanning process; This user as far as lacking experience has very big help when comparing complicated CT examination.

MOI of the present invention also is applicable to the CT examination of its hetero-organization and organ, such as the inspection of breathing aspect, and breast examination and lung's inspection etc.

The present invention also provides a kind of real-time guiding device; As shown in Figure 5; This guidingdevice 1 comprises a kind of inputgroup judging unit 11, a kind ofstorer 13, a kind of scanneditems inspection unit 12 and a kind ofdisplay unit 14, and wherein inputgroup judging unit 11 is used for judging whether the input group of scan protocols is effective;Storer 13 is used to store the instruct form corresponding with said scanned items; Scanneditems inspection unit 12 is used for organizing when effective in this input, checks whether scanned items in this input group exists to instruct form, if exist, then fromstorer 13, transfers out this and instructs form;Display unit 14 is used to show the said form that instructs.Whether effectively and how to check whether scanned items is effective as for how judging the input group, existing specifying repeated no more here instep 101～103 of MOI of the present invention.

Further;Guiding device 1 also comprises a kind of scanningmode inspection unit 15, is used for when said scanned items instructs form, checks whether said scanned items exists and the corresponding form that instructs of current scanning mode; If exist, then from said storer, transfer out this and instruct form;Storer 13 be further used for the storage with said scanned items in each instructs the corresponding scanning mode of form.As for how checking scanning mode, existing specifying repeated no more here inabovementioned steps 105.

Wherein,display unit 14 comprises an above sub-window, and said sub-window can be deleted or adds based on input.Said display unit also comprises editable picture and/or literal.These aforementioned to the explanation of Fig. 3 and Fig. 4 in existing concrete implementation, repeat no more here.

Further,storer 13 also is used to preserve the form that instructs behind said deletion, interpolation or editor, with it as an original subsequent use form that instructs form.The user can customize the form that instructs that is fit to oneself so on the one hand, on the other hand, when afterwards other patients being carried out similar inspection, also can show this subsequent use form, makes experienced user to conduct experience to the user who lacks experience in this way.

The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
