Technical field:
The present invention relates to communication, computer and field of medical technology, particularly interactive network constitution of medicine image obtained by multipoint searching access implementation method and system.
Background technology:
Along with the digitized realization of various medical informations, and being extensive use of of Internet and correlation technique, telemedicine has become one of focus that current medical science and the network information technology intersect.People are after finishing the information for hospital digital Construction, step up research and utilization high speed information net and setting up wide area network electronic health record (Electronic Patient Record, be called for short EPR) system, it mainly is that same patient canned data data in different hospitals is carried out association by express network (Internet or Private Network), make patient's medical history information can be in network with patient's the situation of seeking medical advice and demand, in the different section office of hospital internal, call mutually between different hospital information systems and the different hospital and flow, because it is professional widely different between medical development level between hospital and the section office, therefore, between the different section office of hospital internal, between the different hospitals, and clinic or the like active demand can provide the network diagnosis of interactive medical digital image, the system of advisory role, enable to effectively utilize medical information, improve clinical diagnose, the level of treatment and health service, quality and efficient, and economize on resources greatly.Develop the network diagnosis of interactive medical digital image, the main bottleneck of consulting system is: because the Radiation Medicine image mostly is high-resolution (〉=2K * 2K, as CR, DR, Mammography etc.), Da Rong body (60-400M, as MR, CT, US Series etc.) image, and with the diverse network store status, various medium form (still images, dynamic image, two dimension or three-dimensional etc.) occur, under the prerequisite that guarantees the medical diagnosis quality, any 2 points on network, adopt the best transmission scheme to obtain image information, and these high-resolution multi-media images are carried out real real-time Transmission, show, handle and interactive clinical diagnose, the consultation of doctors and consulting are difficult to realize perfectly.Present existing telemedicine is seeked advice from, the consultation system situation is more as shown in table 1.
Table 1: remote medical consultation with specialists at present, consulting system situation are relatively
| Existing remote medical consultation with specialists system | The employing technology | There is situation | |
| 1 | Net meeting system | " share blank " | Picture size little (512 * 512) |
| 2 | Expert's center mode | Transmission of PACS remote image and demonstration have central store, and transmitted image is arranged the consultation of doctors in advance | Image is in consultation of doctors front transfer, need spend 4～24 hours, non-online, non real-time is had access to, and can not repeatedly select different experts, place |
| 3 | The point-to-point consultation of doctors | Images between two image consultation of doctors work stations, the long-range then radiation consultation of doctors | With different expert consultations, distinguish transmitted image to expert system |
From table 1, can find, use net meeting system (Tele-VideoConference) or carry out remote medical consultation with specialists by the special line video system, owing to adopt " sharing blank " (Shared WhiteBoard) technology, permutable data volume of institute and information are limited, so poor image quality of holding a consultation, the picture size of being held very little (512 * 512), both sides' operation can not be synchronous, can not carry out image processing etc. simultaneously.In addition, owing to be subjected to the restriction of wide area network bandwidth, therefore teleradiology on, the consultation of doctors are mostly adopted expert's center mode (Expert Center), are carried out with non-online (off-line), non real-time mode at present, be image before the consultation of doctors, spend 4～24 hours (owing to be high-resolution, Da Rong volume image) by PACS (image transmission and storage system) remote transmission to its storage system, then, again by long-range expert by PACS to image studies (may take on the telephone with the requesting party betwixt and carry out state of an illness inquiry), draw diagnostic result and pass the requesting party back.This mode can solve non-emergent case, but both sides can not the simultaneous operation image during the consultation of doctors, and distance perspective is strong, and consultation of doctors effect and efficient are not high.And " point-to-point " pattern, its limitation is that image transmits complicated when holding a consultation respectively with a plurality of experts.
Summary of the invention:
In sum, how to overcome the weak point of prior art, utilize the net structure grid environment, on existing PACS system and consultation system basis, design a kind of can on express network, carrying out fast to the complicated state of an illness or " acute disease " patient Radiation Medicine image, in real time, the real-time diagnosis of interactive operation, consulting is a technical problem to be solved by this invention, therefore, the object of the present invention is to provide a kind of interactive network constitution of medicine image obtained by multipoint searching access system and its implementation, be characterized in: a real-time interactive with real meaning, the multiple spot addressing, the best transmission scheme is obtained image and is carried out the medical digital image network diagnosis that SRC is handled image, consulting system, the consultation of doctors can be to obtain/to extract image in several ways, effectively utilize network bandwidth resources, consultation of doctors side " does not have distance " when consultation of doctors sense, its consultation of doctors effect is equal to both sides' consultation of doctors that " sits together ", thereby given full play to a small amount of medical expert's speciality, and serve the numerous common people, to improve the numerous common people's medical treatment ﹠ health level.
Technical scheme of the present invention is as follows:
According to a kind of interactive network constitution of medicine image obtained by multipoint searching access of the present invention system comprise number at least be a plurality of image storage systems of 2 and at least number be a plurality of consultation of doctors work stations of 2, said image storage system, be exactly image management and communication system (Picture Archiving and Communication System, PACS) some of server, its basic function is to receive various medical science DICOM (the Digital Imaging andCommunications in Medicine) image that sends from each acquisition gateway, various images are carried out Classification Management and storage, DICOM is provided communication, WEB or other communication service, the WEB image querying that image storage system provides extracts interface, and the DICOM image that image storage system stored all uses unique identifier UID that it is indicated and discerns; Said consultation of doctors work station is that the doctor is used for instrument that digital medical image is diagnosed, handled, can show and handle any medical science DICOM image (CT/MR/CR/DR/US/DSA/PET etc.) and non-DICOM image, consultation of doctors work station supports DICOM or other interface based on tcp/ip communication agreement (comprising http protocol) to be connected with PACS or image storage system system; Said a plurality of image storage system can be separate operation, also can these storage systems be constituted a save mesh by a management server, each memory all is a node in the grid, DICOM and WEB Image Communication service is provided, under grid environment, image storage system that the mesh-managing registrar is can registration management all and consultation of doctors work station, and the distributed intelligence on the storage system of registration all images in grid, consultation of doctors work station query image information to the mesh-managing registrar, obtain this image and be kept at information on which storage system, therefrom select best storage system download images to show, handle; Be to support remote diagnosis, consulting, teaching etc., the remote medical consultation with specialists module of consultation of doctors work station is integrated a kind of bidirectional remote control treatment technology based on event-driven mechanism.
System of the present invention is according to the notion of N layer model, integrated application Client/Server (client/server of the present invention, C/S) pattern and (Browser/Server) B/S pattern composition network schemer consultation of doctors model, the DICOM view data follows the DICOM agreement by image documentation equipment or PACS server or other mode based on ICP/IP protocol is sent to image storage system, it between them typical C/S pattern, view data follows http protocol by image storage system or other is sent to consultation of doctors work station based on ICP/IP protocol, is typical B/S pattern between them.Can carry out interactive diagnosis, consulting to medical image between any two clients (consultation of doctors work station), interactive diagnosis between the client (consultation of doctors work station) is carried out according to point-to-point, and the image that interactive operation is handled can be from grid arbitrary node image storage system or different independent storage system obtain, consultation of doctors image does not need to be transferred in advance consultation of doctors work station, and all consultation of doctors work stations are shared the view data on the image storage system.The consultation of doctors work station that participates in interactive diagnosis, consulting can use image UID that image is inquired about to said a plurality of storage systems, select best storage to put real-time download images (as the fastest point) and show processing to consultation of doctors work station, the image of downloading can be saved in the local data base of consultation of doctors work station, when showing this image once more, can directly plant from this locality into; Because patient's medical history information can the situation of seeking medical advice and the demand with patient call mutually, flow and backup between the different section office of hospital internal, different hospital information system or different hospital in network, same width of cloth image may be kept on the image storage system of different departmental information systems or different hospitals simultaneously, when carrying out interactive diagnosis, the consultation of doctors can be to show, to handle from download same image from own nearest image storage system according to nearby principle, thereby under the situation that does not influence the interactive diagnosis effect, reach the fastest image display speed.Adopt local mouse and remote mouse interactive operation or processing image when real-time interactive diagnosis, consulting and become one group of message to pass to the other side according to certain rule encoding operating result, UID as image passes to the other side, please the other side download, and the other side utilizes this UID multiple spot to inquire about this image, and from best storage system node download etc.; Consultation of doctors requesting party can hold a consultation alternately with any expert who inserts consultation of doctors network, do not need once more images to give the other side, consultation of doctors side only transmits the small data quantity message such as control information of mouse to image each other, simultaneously long-range and local image is operated then, and when interactive diagnosis, in order to reduce late effect on the one hand, do not increase the data volume of network service on the other hand, do different transmission by the TCP circulation road with the UDP datagram passage respectively according to the significance level of message; When considering the consultation of doctors, the display that consultation of doctors both sides use is also inequality, and the requesting party uses regular display as the consultation of doctors, and expert side uses high resolution display, image shows the relevant coordinate technology with image of employing, and image is simultaneously displayed on the display of both sides' different resolution when the consultation of doctors; Because consultation of doctors image is kept at image storage system, when the third party wishes to add the consultation of doctors, need the image of the consultation of doctors not need initiatively to resend to the third party, get final product but directly extract from image storage system; The consultation of doctors based on this pattern is simpler with respect to the consultation of doctors of traditional ad hoc mode.
The interactive network consultation of doctors method of medical image is obtained in a kind of multiple spot addressing according to the present invention, and its consultation of doctors step comprises:
＜1〉carrying out image prepares: the image on image documentation equipment or the PACS server is transferred to image storage system carries out Classification Management and storage, or be forwarded to other or image store system in strange land backs up storage, the clinician extracts interface by the image querying that image storage system provided, according to order of priority inquiry different images storage system, select required DICOM image, be sent on the consultation of doctors work station with the form of data flow with HTTP or other communications protocol and show, to handle, diagnose, work such as report.
＜2〉request real-time interactive diagnosis, consulting: the clinician uses consultation of doctors work station that medical image is diagnosed, run into query and then ask the consultation of doctors, the client that all that list from the client side list that the WEB of image storage system service is provided have been registered at grid node or image storage system, select another client of wanting to carry out interactive diagnosis with it, connect then, start the consultation of doctors, when a certain side who holds a consultation inquires about from image storage system, when a patient's of selection image shows in the extraction image, this image UID can send the other side to by the remote medical consultation with specialists module, the UID that the other side can come according to biography automatically, according to nearby principle from showing from own nearest image storage system download images, handle: if the remote medical consultation with specialists client does not have corresponding image in its local image storage system, then on the image storage system of being registered on this consultation of doctors work station, inquiring about, extract, the image that inquires is downloaded demonstration to be handled, consultation of doctors both sides' the image all processing after consultation of doctors work station shows is an ad hoc mode, consultation of doctors both sides can operate by synchronizing interactive, handle image, and use phone to carry out speech exchange, transmit this moment is operation or processing messages to image, the message byte number is fewer, transmission time is very short, consultation of doctors effect is equal to both sides' consultation of doctors that " sits together ", the amplification that both sides can synchronizing interactive application drawing picture, dwindle, contrast/brightness adjustment, rotation, smoothly, measurement and enhancing etc.;
＜3〉further inquiry/extraction case history image document: during holding a consultation, either party is as if wanting to check the patient history image document, can inquire about/extract this patient history image document that is stored in other PACS server or other image storage system, can add the row of the message of holding a consultation after these image documents adopt nearby principle to obtain, continue the consultation of doctors.
Effect of the present invention:
Consultation of doctors requesting party's (promptly proposing a side of consultation of doctors request) can be for being positioned at the consultation of doctors work station of clinical department.Consultation of doctors requesting party is continuous with different image documentation equipment or image storage system, obtains different types of medical image.When query takes place when checking image the doctor, can propose consultation of doctors request to dept. of radiology or other experts' consultation of doctors work station by phone, and not need the expert from other places or the strange land diagnosis of coming.After distant place doctor agreed the consultation of doctors, both sides started interactive multiple spot medical digital image network consultation system in this locality separately.In real-time consultation of doctors process, the both sides that hold a consultation, the image that synchronisation is downloaded from image storage system shows (what confirm mutually that both sides operate by image UID is same width of cloth image), the simultaneous operation image, as amplify, dwindle, brightness/contrast adjustment, parameter measurement etc., and the interchange by phone simultaneous voice information is on one side both sides doctor just can discuss like this, on one side in the enterprising row labels of image, sensation is as both sides' consultation of doctors that " sits together ".In addition, the software of interactive medical digital image network consultation system is used to control the prior image of demonstration of having downloaded by TCP/UDP transmission mouse and process information respectively in the consultation of doctors process, and do not need images, guarantee real-time, the no hysteresis quality of interactive operation.Image shows the relevant coordinate technology with image of employing, can use the different resolution display and the while display image consultation of doctors both sides, makes both sides' the correct expression mutually of operating result.During the consultation of doctors, if the auxiliary consultation of doctors of patient's history's image document that either party want to check all can be stored in this patient image in the grid node PACS server according to image DICOMUID inquiry/extractions, and these data are added the row of consultation of doctors information, and continuation is held a consultation.Obviously, the present invention has following characteristic:

The first side of consultation of doctors first (clinician) is with the consultation of doctors work station among Fig. 1 21 expression,
Consultation of doctors side's first of present embodiment is formed (not shown) by demonstration diagnostic work station, network communication interface and a phone (optional), and clinician's consultation of doctors work station is directly connected to for example a certain image storage system of hospital 12.Arm holder for radiographic imaging apparatus is sent to image storage system 12 to medical image continually, and this image storage system 12 also can be forwarded to image another set of (long-range) storage system 1N, is used for backup or other clinical service.The medical image that arrives image storage system 1N meets dicom standard, and the image kind is supported X-ray, CT, all kinds of medical images such as CR, MR, and image resolution ratio reaches 4000 * 5000.The doctor of the clinical department of consultation of doctors work this moment 21 has a question when checking image, can put through the phone of radiology department, proposes the consultation of doctors.After the radiologist agrees, both sides open interactive multiple spot addressing and obtain the network diagnosis of medical digital image information, consulting system program, the either party can use interactive multiple spot addressing to obtain the network diagnosis of medical digital image information, consulting system software, from client side list, select the other side to set up consultation of doctors agreement, begin the consultation of doctors, consultation of doctors both sides show diagnosis from downloading the DICOM image with close separately image storage system synchronously, as the clinical department institute-level image storage system 12 of taking up a job as a doctor, dept. of radiology downloads from its dept. of radiology's image storage system 12.Consultation of doctors process both sides use mouse synchronously, interactive operation consultation of doctors image, and use communication on telephone view separately.Also can join the consultation of doctors process during consultation of doctors from close separately PACS server quick search/extraction patient's history image.
Its structure diagram of interactive network constitution of medicine image obtained by multipoint searching access systems soft ware of present embodiment as shown in Figure 2, design philosophy provides the work station 21 of can not only holding a consultation in this locality, also can be in the mechanism of remote medical consultation with specialists work station 2N control image data stream.This control must all be equal to this place and remote parties, could guarantee that like this both sides' operation can be synchronously with in real time.
1: system software architecture as shown in Figure 2, by forming with lower module:
1) the image querying module 61: from the relevant information of image storage system or consultation of doctors work station local data library inquiry medical image;
2) the image receiver module 62: according to DICOM, HTTP or other agreement based on TCP/IP, receive the DICOM medical image;
3) the image memory module 63: preserve the received DICOM medical image of image receiver module;
4) show processing module 64: show, handle the DICOM medical image;
5) incident sends and receiver module 65: local and remote message route.
2: incident or message-driven mode:
The running of whole procedure is dependence incident or message-driven.Demonstration processing module 64 has been finished the function that image shows.The user operates GUI window or display image, then produces an incident, sends to show processing module 64, realizes image management and image processing function, adjusts as the Window/level contrast of image, amplifies/dwindle, rotation etc.Incident sends and receiver module 65 is for the bidirectional remote controlling Design of remote medical consultation with specialists.Because the incident that GUI produces is rudimentary, system's dependence incident comparatively speaking, and remote medical consultation with specialists need be under the system of different hardware configurations transmission information, system is provided with an incident interpreter, and rudimentary incident is converted to application-layer events.Application-layer events after being converted has two whereabouts: one of them copy is used to adjust the local application state, and another copy is encoded and message is passed to the module incident sends and receiver module 65.After incident transmission and receiver module 65 obtain coded messages, they are sent to remote node.Incident transmission and 65 whiles of receiver module are receiving remote information also, and reception information is by the incident interpreter, and the change event state is assigned to image and shows that event handling is equal to local event in the processing module 64.
3: the message coding rule:
Consider that TCP/IP socket forms the nagle algorithm that bigger network data newspaper sends for reducing the network traffic employing with little information in realizing, even and cancellation nagle algorithm, but, all can make the remote mouse of system when the consultation of doctors, move tangible hysteresis owing to increased network traffic.In order to address this problem,
1) incident is divided into two classes: influence the reference event of the take charge part and the interim state of representation program of final Application Status, the setting of reference event is only in order to make remote operation continuously and for instant.The part of taking charge sends by the TCP circulation road, can guarantee like this to transmit and the state consistency of both sides' application program.The UDP datagram passage is used in the transmission of reference event, and instantaneous transmission can be provided.Because reference event need not keep Application Status, though so datagram transmission " packet loss " phenomenon is arranged, the loss of reference event can be neglected by safety.
2) each message is provided with two sequence counters, can eliminates the negative effect of the message rearrangement that brings by datagram transmission.
