The invention relates to positioning image and position line, can be applied to Medical Imaging, Graphing of Engineering neck Domain and other fields for being related to positioning image and position line are sketched lower positioning image and are determined below by taking Medical Imaging as an example The application of bit line：

In Medical Imaging, such as CT, MR Medical Imaging, go out for the ease of rebuilding 3-dimensional image or diagnosis The size and shape of lesion, the relevant technologies can be that each image determines positioning image in medical image sequence, then calculate each Position line of the image on positioning image, then the spatial relation between different images, and then basis are determined by position line Spatial relation carries out 3D image reconstruction or diagnoses the size and shape of lesion.

Schemed come when determining the spatial relation between different images, inevitably operation positions by position line Picture, position line or the corresponding image of position line, these, which are operated, may trigger the rendering for positioning position line on image, and the application The designer of scheme is had found by a large amount of analytic demonstration, due to relevant technology, the positioning on calculating positioning image After line, acquiescence be using position line with positioning image as the content of same piece image, the two can be configured in same container into Row renders display, and as shown in Figure 1A, position line is to position the lines of the horizontal and vertical centre of image, and the gray scale layer of the bottom is the back of the body Scape.Therefore, to the operation of positioning image, position line or the corresponding image of position line, in the case of the rendering for triggering position line, Positioning image can be rendered while rendering position line, position line and positioning image are rendered as a whole, this is to wash with watercolours The resource consumption of dyeing equipment is larger.If rendering apparatus processing capacity it is limited or it is frequent triggering position line rendering, it is likely that Longer time is expended, the rendering of position line could be completed, therefore easily the low problem of position line rendering efficiency occur.Concrete application When to Medical Imaging, position line rendering efficiency is low, can not well adapt to tele-medicine doctor be accurately positioned patient's lesion, It was found that the scene of subtle lesion, is also unsuitable for the scene of progress positioning operation under the conditions of massive medical image data, because these Under scene, position line and positioning image are rendered as a whole, and it is low further to highlight position line rendering efficiency Problem brings poor usage experience to user.

In view of the low problem of position line rendering efficiency in the related technology, the embodiment of the present application can be by the rendering of position line (separation) is decoupled with the rendering of positioning image, the position line after decoupling and positioning image are as shown in Figure 1B, and difference is respectively configured Container in, the gray scale layer of the bottom is background, can in positioning image registration to same container.When specific implementation, it will work as The coordinate data of preceding image position line on positioning image, is configured in independently arranged rendering container, to be held by rendering Device carries out independent rendering to position line, due to position line with position image configurations in different containers, it is possible to by the two Rendering separate, without while rendering position line, render and position image.It is fixed to be rendered accordingly, with respect to the relevant technologies The case where positioning image must be rendered while bit line, can save the resource for rendering positioning image consumption to a certain extent, Improve position line rendering efficiency.

When being applied to Medical Imaging, medical image and the overall performance of position line can be improved, is utmostly ensured Medical doctor also can clearly browse faultage image while smooth operation position line, more accurately to obtain lesion Spatial position.The position line Rendering operations of lower the embodiment of the present application are discussed in detail below in conjunction with attached drawing：

It, can be with referring to Fig. 2, Fig. 2 is the flow chart of the position line rendering intent shown in one exemplary embodiment of the application Applied to computer equipment, including step S201 to step S203：

Step S201, the coordinate data of position line of the present image on positioning image is obtained.Number of coordinates mentioned herein According to include for indicate position line positioning image on position data, can be that position line is positioning coordinate system where image In data, can also be other can indicate position line positioning image on position data.

Step S202, the coordinate data is configured to the rendering container for carrying position line；The rendering container with The positioning image corresponds to, and exists independently of the container for carrying the positioning image.

Step S203, by carrying out rendering processing to the position line with the rendering container postponed.

The computer equipment of the embodiment of the present application application, can be the various electronic equipments with image-capable, example As personal computer, laptop computer, cellular phone, camera phone, smart phone, media player, learning machine, intelligence are handed over Mutual tablet etc..Application program (client) with image processing function can be installed, such as CS client in these electronic equipments End or BS clients, application program (client) mentioned herein can be the applications positioned for Graphing of Engineering or medical image Program (client) can also be the application program (client) that other are related to positioning image and position line.

In practical application, the client in user's operation computer equipment can start the position line of the embodiment of the present application The flow of rendering intent introduces the triggering that lower position line renders function, in other embodiment by taking Medical Imaging as an example below In, the client of user's operation other field can also start the flow of the position line rendering intent of the embodiment of the present application, herein It repeats no more.

In one embodiment, the client installed in computer equipment is the client positioned for medical image, medical treatment It, can be by the client installed in computer equipment, really when doctor rebuilds 3-dimensional image or diagnoses the size and shape of lesion Need image and positioning image, the embodiment of the present application in medical image sequence to be shown that will currently need medicine shadow to be shown surely As the image in sequence is referred to as present image, the quantity of present image is by the image window quantity in the display interface of application program It determines.Under certain scenes, the same time is only able to display a width present image, under other scenes, it is also possible at the same show two width with On present image, the embodiment of the present application is without limitation.

Client can instruct according to the user's choice before display positioning image and present image, first determine and need to obtain The present image for taking position line, in the case where predefining out the scene of positioning image of the present image, such as present image and positioning Image is shown, the coordinate data of position line can be obtained according to present image and positioning image.

In the case where being not determined by the scene of positioning image of the present image in advance, such as present image it has been shown that positioning image It does not show, location data can be obtained according to present image, which includes the seat of the data and position line that position image Mark data.In view of the present processes need to decouple positioning image with position line, if in the location data obtained, positioning Together with the data mixing of position line, the embodiment of the present application is needed from the location data data of image, is identified and is carried The coordinate data of the position line is taken, realizes the separation of positioning image and position line, position line is individually rendered so as to follow-up.

For obtaining the detailed process of location data or position line coordinate data, type difference, current figure in client As it is different when, acquisition process is also different, and several situations exemplified below illustrate：

Situation one：If client is CS clients (client under Client/Server frameworks), medical image sequence It is stored in local, it, can be by CS clients according to medicine in the case where being not determined by the scene of positioning image of the present image in advance Position relationship between image sequence determines positioning image, and in an example, medical image sequence is CT Slice Sequences, since CT is cut Piece sequence is the cross-section image of same direction (X-direction in such as three-dimensional coordinate) different location, and CS clients can be according to CT Section sequence, the CT images for reconstructing the vertical direction of the CT Slice Sequences are positioning image, and store positioning image, are carried here The CT images and/or the Z-direction in three-dimensional coordinate that the positioning image arrived is the Y direction in three-dimensional coordinate.

In turn, CS clients can respond the selection of user, display positioning image and present image, further according to two images Position relationship calculate the coordinate data of position line of the present image in positioning image.Position line mentioned herein is current figure As the intersection with positioning image, the specific pattern of coordinate data can be determined, coordinate as the set by set coordinate system System is the image coordinate system where positioning image, and the coordinate data of position line can specify bit line belonging positions in positioning image Coordinate.

In another example, medical image sequence is MR Slice Sequences, since MR Slice Sequences include the section of different directions Image, image reconstruction direction (the X-axis side in three-dimensional coordinate that CS clients can be sliced according to any two in MR Slice Sequences To, Y direction or Z-direction), by one of two different slices of image reconstruction direction as positioning image, another conduct Present image, and record the positioning relation of two images.It, can be according to two when subsequent response user selects to show this two images The position relationship of width image calculates the coordinate data of position line of the present image in positioning image.Position line mentioned herein Coordinate data is as described above, details are not described herein.

It should be noted that client is under the certain scenes of CS clients, CS clients can cache positioning image, current Image and present image the position line of positioning image coordinate data, if CS clients close present image and positioning image In latter timing section, needs to be again turned on present image and positioning image, be equivalent to the positioning for having determined that present image in advance Image, the present image that can be selected from buffer zone calling and obtaining user, the positioning image and present image of the present image are fixed The coordinate data of position line in bit image.

Situation two：If client is BS clients (Web client, the client under Client/Server frameworks), doctor It learns image sequence and is stored in Web server, Web client sends position line request to Web client, this is not determined by advance Under the scene of the positioning image of present image, position line request includes the unique mark of present image, then by Web server It is asked according to position line, transfers out present image, the positioning image there are positioning relation with present image is determined, further according to two Spatial relation between width image calculates the coordinate data of position line of the present image in positioning image, and positioning is schemed The data of picture and the coordinate data of position line are back to Web client as location data.

In the case where having determined that the scene of positioning image of the present image in advance, position line request includes present image Unique mark and position image unique mark, Web client to Web client send position line request, Web server according to Position line is asked, and transfers out present image and its positioning image is calculated further according to the spatial relation between two images The coordinate data of position line of the present image in positioning image, Web client is back to by the coordinate data of position line.

In Medical Imaging, Web server with the format storing medical image of the DICOM file of standard, standard DICOM file is made of file header and data information.DICOM file head (DICOM File Meta Information) includes The relevant information of mark data set.Data information is data element of the group number of DICOM data elements Tag since 0x0008 The data set that element is constituted.Data information can be divided into image file data information and non-image files data information by content.Image File data information is the complex of multiple information objects, including patient (Patient), inspection (Study), serial (Series) With the data elements such as image (Image) data；Non-image files data information is managed, just by directory management, patient management, inspection It examines the management informations such as management, results management and other information is constituted.

The embodiment of the present application can use the data of DICOM file when Web server calculates the coordinate data of position line Patient Position (0018,5100), ImageType (0008,00008) in information, ImagePositionPatient(0020,0032)、IamgeOrientationPatient(0020,0037)、 PixelSpacing (0028,0030), Rows (0028,0010), Columns (0028,0011) and Frame of The attributes such as Reference UID (0x20,0x52).

The value of the wherein TAG (0018,5100) of image has determined that the direction of unified coordinate system, i.e., all image sequences Parameters are all that (according to the standard of DICOM3.0) provided is being calculated with reference to the unified coordinate system.

The value of the TAG (0020,0032) of image has determined that the coordinate X, Y, Z of the first pixel of this image (" upper left side ") Value.The value of it and TAG (0020,0037) can determine the space coordinate of all the points of entire image.

The value of the TAG (0020,0037) of image can determine the unit row vector and unit column vector of image, and the two Apposition (cross product) is exactly unit normal vector, therefore can obtain 3 unit vectors from TAG (0020,0037).

The value of the TAG (0028,0030) of image can determine the actual physics width and generation that each pixel of image represents The actual physics height of table.

The value of the TAG (0028,0010) of image can determine the height of image.

The value of the TAG (0028,0011) of image can determine the width of image.

In addition, the displacement mark of positioning image and the unique mark of present image have 3, it is respectively StudyInstanceUID (check unique mark), SeriesInstanceUID (object sequence unique mark) and SopInstanceUID (object unique mark), is briefly referred to as StudyUID, SeriesUID and SopUID, these three UID ginsengs Number is used to specify the DICOM objects of request, and Web client is based on WADO agreements, and the positioning of URL forms is sent to Web server Line is asked, and variable url_prefix comes the constant part in record access address defined in position line request, it is assumed that Web server Access path is that "/wado.cgi ", according to the requirement of WADO agreements, the URL pattern that browser sends out request is as follows：

Url_prefix="/wado.cgi？RequestType=WADO&StudyUID="+StudyUID+ "s &Se Ries-UID="+SeriesUID+ "s &SopUID="+SopUID+ " &LocalizerlineUIDS="+Localiz erline-UIDS；

When medical image is CT sectioning images, Web server is good fixed having predefined after receiving position line request Under the scene of bit image, can by the Image Type attributes of data element in DICOM file data come judge image whether be The positioning picture of present image, if LOCAL IZER then indicate that the image is positioning image；If AXIAL is then expressed as being sliced Image.

When medical image is MR sectioning images, after receiving position line request, Web server can not lead to Web server ImageType attributes are crossed to judge.In view of MR positioning images are an opposite, mutual concepts, as long as being deposited between two images In intersection, then any image is all likely to become the positioning figure of another image in MR Slice Sequences.It therefore, can basis The image reconstruction direction of MR slices determines the positioning image of present image.

It should be noted that client is under the certain scenes of BS clients, BS clients can cache positioning image, current Image and present image the position line of positioning image coordinate data, if BS clients close present image and positioning image It in latter timing section, needs to be again turned on present image and positioning image, can be selected from buffer zone calling and obtaining user current Image, the coordinate data of the position line of the positioning image and present image of the present image in positioning image.

For the location data got, the embodiment of the present application is in order to avoid whole as one using position line and positioning image Body is rendered, can be by the data configuration of position line to the rendering container for carrying position line, the rendering container and positioning Image corresponds to, and exists independently of the container of carrying positioning image.Here the coordinate data for rendering container and removing carrying position line Outside, other pixel datas such as color, the gray scale of position line can also be preset, further, it is also possible to encapsulate there are many rendering function, Such as：According to the currently supported rendering functions of equipment CPU, position line is rendered.The container of carrying positioning image and rendering The function of container is identical, is all the container for rendering image, the difference is that the image data of carrying is different, pair of rendering As difference, details are not described herein.

Configuration render container during, if the quantity of present image be two width with when, in order to reduce the configuration of equipment Consumption, the coordinate data of position line that can be by each width present image on same positioning image, configures to same rendering and holds Device.

In certain examples, before configuration renders container, if being that position line creates rendering container in advance, directly by position line Data configuration to advance environment rendering container.If container is rendered without being created for position line in advance, by position line Data configuration to the rendering container for carrying position line before, need according to positioning image, create with position image it is corresponding Render container, then by the data configuration of position line to establishment rendering container.Here why container and positioning image will be rendered It is corresponding, it is when subsequently showing position line, to need to show position line because position line is intersection of the present image in positioning image Onto positioning image.

In one example, dynamic creation can be carried out according to unique mark of positioning image, the rendering container being created that passes through It positions the unique mark of image and positions image for that in other examples, positioning image can also be corresponded to, other modes is taken to create Rendering container is built, details are not described herein.

In another example, when configuration renders container, it is contemplated that the difference between image coordinate and screen coordinate system can pass through Operate the rendering container coordinate data being configured to for carrying position line below：

According to the mapping relations between image coordinate system and screen coordinate system, the coordinate data is mapped to screen coordinate System.Here mapping relations can be between image coordinate system and screen coordinate system transformation relation, primarily to after convenient Continuous display position line.

The coordinate of starting pixels point is identified from the coordinate data after mapping and terminates the coordinate of pixel, and is stored to institute State rendering container.In other examples, other modes of operation were also opened by the data configuration of position line to container is rendered, will such as be determined The coordinate of all pixels point of bit line is stored to container is rendered, and the embodiment of the present application is without limitation.

It, can be according to specific application scenarios, using corresponding technological means, by matching for the rendering container postponed The rendering container postponed carries out rendering processing to position line.Such as：The method of the embodiment of the present application is applied and Web client, can To use the painting canvas attribute of HTML5, by carrying out rendering processing to position line with the rendering container postponed, wherein in HTML5 <canva>Element can be used as and render container.
