It referring to fig. 2, is one embodiment block diagram of scan data processing method of the present invention, this method can be applied to workPlatform, this method comprises:
Step 201, after the completion of current subject scanning being determined according to the scanning information that scan control end is transmitted, institute is receivedState the scan data of scan control end transmission.
After the scanning device using CT equipment scans subject and generates original scan data, scan control end is justBe stored with scanning device current subject is scanned check after all original scan datas for obtaining namely original sweepTrace designs picture.
According to the difference of the scanned position to current subject, original scan image can be divided into different sequences, oftenThe multiple original scan images scanned for a certain position are contained in a sequence, for example, when heart, knee to subjectWhen two positions of lid are scanned, sequence quantity is then 2, and one of sequence is contained original sweeps for what heart scanning obtainedTrace designs picture, another sequence then contains the original scan image scanned for knee.
After obtaining all original scan images, scan control end can obtain scanning letter according to all original scan imagesBreath, scanning information may include all original scan images sequence quantity and each sequence in include data bulk, hereSequence in include data bulk be to be directed to the quantity of the original scan image that some position is scanned；Scanning information is alsoIt may include the essential information of subject, for example, the information such as the ID of subject, height, weight, so that workbench is receiving thisAfter scanning information, the doctor of workbench can identify subject corresponding with the scanning information according to the essential information.ScanningObtained scanning information is sent workbench by control terminal, scanned with the subject for notifying workbench current, and will be rightThe original scan image that current subject scans successively is transmitted to workbench according to each sequence order.
Step 202, judge whether to meet described in execution according to waiting task, scanning information and received scan dataThe condition of waiting task.
It after workbench receives scanning information, that is, can determine that scanning device is scanned to current subject, cureLife can choose operation corresponding with current waiting task by clicking the task processing function option of workbench, with triggeringWorkbench judges whether scan data meets to be processed according to waiting task, scanning information and the scan data receivedThe treatment conditions of business.
In present embodiment, what waiting task can execute original scan image according to actual business requirement for doctorPost-processing operation is shown including two dimension or three-dimensional image are edited, generated to image, extracts specific tissueShow, MPR and film printing etc..
When waiting task is that the whole of specified sequence is needed to specify scan data, waiting task be can be for oneThe task that whole scan images in a or multiple sequences are handled, such as: to the Three-dimensional Display of image, tissue segmentation, moreLevel reconstruction etc.；
When waiting task is the part invisible scanning data for needing specified sequence, waiting task be can be for fingerThe task that the parts of images of sequencing column is handled, such as: it checks certain specific piece image, parts of images progress film is beatenPrint etc..
In present embodiment, workbench is determined according to waiting task, scanning information and received scan data to be metThe condition for executing the waiting task can be there are many situation:
It is received on the workbench when the waiting task needs the whole of specified sequence to specify scan dataScan data includes that the whole of the specified sequence specifies scan data；
When the waiting task is the part invisible scanning data for needing specified sequence, received on the workbenchScan data include the specified sequence part invisible scanning data.
For example, after the completion of to current subject scanning, the scan data that scan control end obtains include: sequence 01 andSequence 02, wherein sequence 01 and sequence 02 respectively include image 1-100.Workbench receives the scanning of scan control end transmissionInformation then includes sequence 01, amount of images 100；Sequence 02, amount of images 100.
If waiting task is that the invisible scanning data 1-100 of specified sequence 01 is needed to carry out MRP batch processing, then can be withFirst check for scan data that workbench is currently received whether include specified sequence 01 1-100 all images, if workReceived scan data includes the invisible scanning data 1-100 of the specified sequence 01 on platform, can determine received scanningData, which meet, currently executes the condition of MRP batch processing in workbench, on the contrary, then condition is not satisfied.
For another example if waiting task is to carry out film printing to the invisible scanning data 50-60 of specified sequence 01, equallyCan first check for scan data that workbench is currently received whether include specified sequence 01 invisible scanning data 50-60,If including, it can determine that the scan data received meets the condition for currently executing film printing to image 50-60 in workbench,On the contrary, then condition is not satisfied.
Step 203, when determining that received scan data meets the condition for executing the waiting task, then by the workMake platform and respective handling is carried out to the scan data according to waiting task.
When judging result is to determine that currently received scan data meets the treatment conditions currently handled in workbench,Illustrate that the scan data handled according to waiting task is all transmitted, the doctor of workbench without waiting canCorresponding processing is carried out to received scan data according to the waiting task.
Compared with the existing technology, this example embodiment is carrying out original scan image according to different waiting tasksWhen being further processed, whole scan datas is transmitted to after workbench without waiting for scan control end and carries out respective handling again,But by judging currently whether received scan data meets the treatment conditions of waiting task to workbench, and determining completelyRespective handling is carried out to the scan data by workbench when sufficient condition, therefore, the present invention can shorten the number to be scanned such as workbenchAccording to transmission time, and then promoted to the treatment effeciency of image.
In embodiments of the present invention, when judge received scan data be unsatisfactory for execute waiting task conditionWhen, in order to further enhance the treatment effeciency to image, the present invention can also be by sending waiting task to scan control endTask handle request, request scan control end assist execute waiting task, specifically, the method for the present invention further include:
The task processing request that the waiting task is sent to the scan control end, so that scan control end rootRespective handling is carried out to the scan data according to the waiting task, and receives the task processing that the scan control end is sentAs a result.
In another embodiment of the present invention, when judge received scan data be unsatisfactory for execute waiting task itemWhen part, in order to further enhance the treatment effeciency to image, the present invention can also send prioritised transmission request to scan control end,The scan data to be processed that do not transmit is preferentially sent to workbench processing by scan control end, specifically, the method for the present invention is alsoInclude:
Prioritised transmission request is sent to scan control end, is preferentially obtained from the scan control end and executes described to be processedThe scan data to be processed that do not transmit needed for business；
The scan data to be processed according to received scan data and preferentially obtained is completed to described to be processedThe processing of task.
In another implementation method of the invention, when judge received scan data be unsatisfactory for execute waiting task itemWhen part, in order to further enhance the treatment effeciency to image, the present invention can also further compare by workbench continue to execute toProcessing task and the time that the correspondence waiting task is handled by scan controller, when then therefrom selection executes waiting taskBetween short workbench or scan control end execute, can farthest save the waiting time in this way, improve working efficiency.Such as figureShown in 3, show for the process in the example when judging that received scan data is unsatisfactory for executing the condition of the waiting taskIt is intended to, comprising:
Step 301, workbench is swept according to having received the corresponding transmission time of scan data and calculate do not transmit to be processedThe corresponding transmission time of data is retouched, the corresponding transmission time of scan data to be processed that do not transmit and the workbench are executedThe time of waiting task is as the first transmission time；
Step 302, the second transmission time of scan control end processing waiting task is obtained；
Step 303, judge whether first transmission time is less than or equal to second transmission time, if so, executingStep 304, then the waiting task is continued to execute by workbench, otherwise, execute step 306, by scan control end processing toProcessing task；
Step 304, Xiang Suoshu scan control end sends prioritised transmission request, preferentially obtains execution from the scan control endThe scan data to be processed that do not transmitted needed for the waiting task；
Step 305, the scan data to be processed obtained according to received scan data and preferentially is completed to instituteState the processing of waiting task；
Step 306, Xiang Suoshu scan control end sends the task processing request of the waiting task, so that the scanningControl terminal carries out respective handling to the scan data according to the waiting task, and receives what the scan control end was sentTask processing result.
In step 301, workbench first according to the invisible scanning data in the corresponding specified sequence of waiting task withAnd received scan data determines the scan data to be processed that do not transmit, determines the scan data number to be processed not transmittedAmount.It then the time required for calculating every image of transmission according to received scan data quantity and transmission time, willTransmitting the time required for every image multiplied by the scan data quantity to be processed that do not transmit is the scanning to be processed that do not transmitThe corresponding transmission time of data.Later, it calculates and executes the time of waiting task in workbench, and to be processed swept what is do not transmittedIt retouches the corresponding transmission time of data and executes the time of waiting task in workbench as the first transmission time.
In step 302, workbench sends to scan control end execute the request of waiting task the time it takes first,Then control scanning end is according to the waiting task pre-calculation process whole scan data and scan control end to the wholeScan data processing sends the temporal summation of task processing result to workbench after completing, and passes as the second transmission timeGive workbench.
In step 303, by judging whether the first transmission time is less than or equal to the second transmission time to determine whetherWaiting task is continued to execute by workbench.
In step 304-305, if judging, the first transmission time is less than or equal to the second transmission time, illustrates not transmitScan data to be processed is less, still, due to scan control end transmission scan data be according to the image sequence in sequence according toSecondary transmission, therefore, even if the scan data to be processed that do not transmit is less, if do not transmit scan data to be processed sequence compared withFor rearward, according to processing mode in the related technology, it usually needs image transmitting that wait front, that it is not needed is completeAt later, capable of just receiving the scan data to be processed that do not transmit really needed, when undoubtedly increasing the waiting of doctor in this wayBetween.Therefore, when judging that the first transmission time is less than or equal to the second transmission time, in embodiments of the present invention, Ke YiyouWorkbench sends prioritised transmission request to scan control end according to the scan data to be processed that do not transmit determined, is swept with requestControl terminal is retouched by the scan data prioritised transmission to be processed that do not transmit to workbench.Workbench receives scan data to be processedAfterwards, the scan data to be processed obtained according to received scan data and preferentially executes the waiting task.
For example, waiting task is to print to the image 50-60 of sequence 01, and current received scan data isImage 1-20 can be sent excellent then can learn that image 50-60 is the scan data to be processed that do not transmit to scan control endFirst transmission request, to request scan control end by image 50-60 prioritised transmission to workbench.
After scan control termination receives prioritised transmission request, preferentially workbench will be transmitted to according to image 50-60.Without waiting for the time for transmitting image 21-49 the image 50-60 of needs can be obtained, and to image 50-60 in the doctor of workbenchIt is printed, and then realizes that workbench works asynchronously with scan control end.
In above-mentioned steps 306, if judging, the first transmission time is greater than the second transmission time, illustrates not transmit to be processedScan data is more, if wait scan control end to continue to transmit scan data to be processed workbench doctor can be made to wait longerBetween, and respective handling is carried out then effectively by scan control end come the invisible scanning data to the specified sequence, it therefore, canTo send to scan control end there is the task of waiting task to handle request, waiting task is executed by scan control end.?After the completion of scan control end is to scan data processing, task processing result is sent to workbench, workbench by scan control endAfter receiving the task processing result that scan control end is sent, doctor can be examined patient according to the task processing resultIt is disconnected, or the task processing result is carried out the further operating such as printing.
For example, it is assumed that waiting task is to carry out MRP batch processing to the image 1-100 of specified sequence 01, if current receiveImage be sequence 01 image 1-10, can determine that currently received scan data is unsatisfactory for executing the waiting taskCondition, then can not currently based on the received the image 1-10 of sequence 01 workbench carry out MRP batch processing.Workbench can rootTask processing request hair is generated according to waiting task MRP batch processing (carrying out MRP batch processing to the image 1-100 of specified sequence 01)It send to the scan control end with reprocessing rate, carries out MRP batches by image 1-100 of the scan control end to specified sequence 01Reason, and scan control end handle after the completion of by scan control end by task processing result be sent to workbench for doctor carry out intoSingle stepping.
In order to avoid in actual moving process of the present invention, scan control end pressure is excessive and can not be sent out in time according to workbenchThe task processing request sent executes waiting task can also receive in embodiments of the present invention at scan control endAfter the task processing request sent to workbench, according to the service condition of itself current CPU, memory, judge whether to execute toProcessing task, when such as scan control end refusal executes the waiting task, the method also includes:
After workbench receives the message for the refusal processing waiting task that the scan control end is sent, continue waiting for sweepingIt retouches control terminal and transmits the scan data to be processed that do not transmit；
After the scan data end of transmission to be processed not transmitted, by the workbench according to the waiting taskRespective handling is carried out to the received scan data.
For example, can preset CPU usage threshold value and memory usage threshold value at scan control end, which is accounted forIt is for judging the whether excessive critical value of scan control end pressure with rate threshold value and memory usage threshold value.Assuming that shouldCPU usage threshold value and memory usage threshold value are the 80% of In-commission Rate.When scan control end is receiving workbenchAfter the task processing request of transmission, scan control end can check the service condition of itself current CPU, memory, if judgement is certainlyThe current CPU of body, memory usage are respectively less than or equal to the 80% of In-commission Rate, illustrate the current CPU in scan control end, memoryOccupancy is lower, can execute waiting task；However, if judging, the current CPU in scan control end, memory usage have surpassedThe 80% of In-commission Rate is crossed, illustrates that the current pressure in scan control end is excessive, scan control end can also send to workbench and refuseThe refusal for executing waiting task absolutely handles message, to execute the operation of waiting task in workbench.
When workbench receives the message of refusal processing waiting task of scan control end transmission, scan control is determinedEnd pressure is excessive, and workbench can continue waiting for scan control end and transmit the scan data to be processed that do not transmit.What is do not transmittedAfter scan data end of transmission to be processed, corresponding position is carried out to received scan data according to waiting task by workbenchReason.
This example embodiment, without waiting will be complete when executing waiting task it can be seen from above-mentioned implementation methodThe scan data in portion is transmitted to after workbench carries out respective handling again, but by whether judging current received scan dataMeet the treatment conditions of waiting task, and dynamically determines that relatively suitable processing end executes to be processed according to judging resultBusiness, therefore, the present invention can shorten the transmission time that workbench waits scan data, promote the treatment effeciency to image, andWhile shortening workbench doctor waiting scan data transmission time, scan control end and work are also further controlledThe operating pressure of platform improves the overall performance of system.
