Embodiment
By reference to the accompanying drawings the present invention is described in further detail below by embodiment.
As shown in Figure 1, one embodiment of the present invention provides a kind of medical image transmission system, comprising: at least one terminal 10, at least one initial data source 40, data acquisition service 20 and configuration service 30.Correlation between them is that terminal 10 is initiated to obtain request of data to data acquisition service 20, and data acquisition service 20 obtains original data source information from configuration service 30, then initiates inquiry request to initial data source 40 and obtains result data.Wherein, data acquisition service 20 communicates with initial data source 40 with terminal 10, configuration service 30 respectively.The reciprocal process of whole system is: terminal 10 is initiated to obtain request of data, responded by data acquisition service 20, data acquisition service 20 obtains the nodal information in attachable initial data source from configuration service 30, then inquiry request is initiated to initial data source 40, obtain the initial data on its attachable image documentation equipment, then initial data is fed back to terminal 10 for its display and image manipulation.
Initial data source 40 is for providing medical image initial data, usually, initial data source 40 uses medical data imaging and communication standard (DigitalImagingandCommunicationinMedicine, DICOM), and possess inquiry/extraction service (Query/RetrieveSCP, SCP full name ServiceClassProvider), the effect of this service is to provide inquiry and extracts medical image.The functional representation initial data source 40 of QuerySCP is after receiving relevant inquiring request, and initial data source 40 can receive the follow-up information inquiry of inspection message layer, sequence layer and image bearing layer etc. that will mention, and returns the result meeting querying condition; And the functional representation initial data source 40 of RetrieveSCP is by image initial data to be asked, send to inquiry by DICOM stores service.By this process, initial data source 40 can respond the inquiry request of inquiry end, and returns the qualified initial data inquired, and completes the acquisition of initial data.
In present embodiment, initial data source 40 is provided with DICOM interface (for convenience of description, be called a DICOM interface), data acquisition service 20 is also provided with DICOM interface (being called the 2nd DICOM interface), and the communication between initial data source 40 and data acquisition service 20 is by a DICOM interface and the 2nd DICOM Interface realization.By dicom standard interface, initial data acquisition can be carried out by standardized mode, and standardization also ensure that the initial data source meeting arbitrarily standard can get initial data by data acquisition service 20.
Configuration service 30 provides the mapping of medical image primary data information (pdi) and data source identification.Here, data source identification can be the device id of operator's easy understand of terminal 10, user-friendly, such as can show the list relevant to initial data source in terminal 10, wherein comprise ID and the title in initial data source, namely data source identification is obtain from this list, is the parameter that terminal 10 is initiated to use when requiring the request of acquisition medical image initial data.Medical image primary data information (pdi) is then the DICOM mark of the data acquisition equipment comprising configuration; Data acquisition equipment refers to the equipment gathering medical image initial data, such as nuclear-magnetism equipment etc.In configuration service 30, it wants management data source to identify the corresponding relation identified with the DICOM of concrete data acquisition equipment, thus provides the concrete link information of needs (being called initial data nodal information) to data acquisition service 20.To again make an explanation by embody rule by way of example below.
By configuration service 30, when initial data source 40 changes, only need the data source information revising configuration service 30 management, thus the simplicity of data source amendment can be realized, and do not affect initial data source 40 and terminal 10.
Terminal 10 generally refers to the workbench that doctor uses, and in image section office, each doctor can distribute a station terminal (also known as diagosis terminal), and it has basic function of browse and post-processing function usually.Post-processing function comprises three-dimensional MPR (Multi-plannerReformation, multiplanar reconstruction), VR (VolumeRendering, volume reconstruction), CMPR (CurvedMulti-plannerReformation, curve reestablishing) etc., terminal operator can independently carry out as required.Post-processing function needs the initial data using medical image, such as MR thin layer data etc.Obviously, each terminal 10 has human-computer interaction interface, can display of medical image, can also receive user operation.In the present embodiment, each terminal 10 also has inquiry based on medical data model and acquisition capability, the request can initiating for obtaining medical image initial data according to user operation.
Terminal 10 uses medical data model to carry out ADM image, and here, medical image comprises the image data after medical image initial data and reprocessing.Described herein and medical data model be a kind of tissue and expression way of information.In the present embodiment, medical data model is four layers, patient information layer, inspection message layer, sequence layer and image bearing layer respectively, wherein in patient information layer a patient information correspondence proving Information Level at least one inspection, one in inspection message layer checks at least one sequence in corresponding sequence layer, and a sequence pair in sequence layer answers at least one image in image bearing layer.In this four layer model, every layer is held suitable attribute, and such as, that patient information layer holds is patient's name, and what inspection message layer held is check data, and what sequence layer held is serial ID etc.In a kind of specific implementation, this four layer model can meet dicom standard.
When using these model management data, need to select certain attribute to perform relevant operation according to each layer.Such as, terminal 10 initiates request (for convenience of describing, here involved model during initiation request is called the first medical data model), then need to select certain attribute to perform the inquiry to medical image initial data according to each layer, such as, first perform the inquiry of patient information layer, then from Query Result, select some attributes to perform the inquiry of inspection message layer, by that analogy; And querying condition is the some attributes extracted from this first medical data model, correspondingly, inquire about the result obtained also to be organized according to this first medical data model.When showing medical image, terminal 10 can use aforesaid four layer models, also can only adopt two-layer model to show (for ease of distinguishing, the model involved by display being called the second medical data model here).Second medical data model only comprises sequence layer and image bearing layer.As shown in Figure 3, the showing interface mode of terminal 10 adopts two-layer model, is window sequence and imaging window, with the display window that window sequence is basic on interface, the multiple images belonging to certain sequence can be shown, the corresponding imaging window of each image in a window sequence.Similarly, the second medical data model is also a kind of tissue and expression way of information.
Because terminal 10 adopts medical data model to carry out management data, data comprise the data that normal diagosis process relates to and the initial data obtained after initiating request, like this, the management of terminal 10 pairs of data is unified, the fusion of initial data and non-primary data (image data as after reprocessing) can be realized in terminal, namely using the part of initial data as current check, thus consistent diagosis flow process can be carried out.To again make an explanation by embody rule by way of example below.
After terminal 10 initiates the request requiring to obtain medical image initial data, data acquisition service 20 receives this request.The proprietary protocol that communication between terminal 10 and data acquisition service 20 can be arranged in advance based on both sides realizes.Like this, when terminal 10 needs to obtain initial data, request is initiated directly to data acquisition service 20, thus terminal 10 can be kept apart with initial data source 40, do not need to relate to the contents such as data source Dynamic Changes, dicom standard, but completed the conversion transmiting a request to dicom standard from terminal 10 by data acquisition service 20 by proprietary protocol.In a kind of specific implementation, terminal 10 is separated physically with data acquisition service 20; In another kind of realization, the two physically can become one, and such terminal 10 and data acquisition service 20 are combined together, obtain initial data from initial data source 40 together, from operator's aspect, data acquisition service 20 similarly is what be hidden, but in fact, the two division of labor processes.After data acquisition service 20 receives the request of terminal 10, corresponding data source identification is determined according to this request, data source identification can be carried in the request of terminal 10 transmission, then according to the data source identification determined, the initial data nodal information corresponding with this data source identification is obtained from configuration service 30, inquiry is initiated to initial data source 40 again according to initial data nodal information, inquiry obtains corresponding medical image initial data, and the medical image initial data obtained is fed back to terminal 10.
By data acquisition service 20, as aforementioned, terminal 10 and initial data source 40 can be made to keep apart, make terminal 10 not by the impact of the content such as Dynamic Changes, dicom standard in initial data source 40; Simultaneously, can be implemented in when not affecting terminal 10, carry out the operation such as interpolation, amendment in initial data source 40 easily, the availability of raising system and flexibility, and, the data source information that data acquisition service 20 is provided by configuration service 30 carries out data acquisition operations, can realize the amendment of real-time data source, namely can random growth data source; In addition, be carry out alternately based on proprietary protocol between data acquisition service 20 and terminal 10, data acquisition service 20 can by a series of proprietary protocols of definition, reach the effect coordinating with terminal 10 and realize more sophisticated functions or solve some problem.Inquiry request as by proprietary protocol transmitting terminal 10 instead of the dicom standard interface by standard.The benefit done like this is, terminal 10 can without the need to understanding the content of dicom standard, the independence of practical function; Efficiency of transmission can be improved again.Three-dimensional reconstruction can be placed on service end for another example to have come, then result of calculation be passed to terminal by proprietary protocol, solve some terminal, such as web version terminal, the problem that three-dimensional reconstruction calculates cannot be performed, enrich the function of terminal.
