Detailed description of the invention

For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention Formula is described in further detail.

Before detailed explanation is carried out to the embodiment of the present invention, first the application scenarios of the embodiment of the present invention is given Introduce.The embodiment of the present invention provide method be applied in terminal, this terminal can for computer, smart mobile phone, panel computer, Notebook computer, Ultra-Mobile PC (English: Ultra-mobile Personal Computer, be called for short: UMPC), Net book, personal digital assistant (English: Personal Digital Assistant, be called for short: PDA) etc. or CT machine, The two-dimensional medical video capturing devices such as NMR, this is not limited by the embodiment of the present invention.Further, this terminal is at least There is display function, be used for showing two-dimensional medical images, and Pseudo-color technology can be carried out to two-dimensional medical images, thus by two dimension Organ on medical image shows with color version.Example, this terminal can be by image processing software display two dimension Medical image, and Pseudo-color technology is carried out to this two-dimensional medical images, this is not limited by the embodiment of the present invention.

Fig. 1 is the flow process of the pseudo-color display methods of histoorgan of a kind of two-dimensional medical images that the embodiment of the present invention provides Figure, sees Fig. 1, and the method can include following several step:

Step 101: by the priority of multiple histoorgans mark and the plurality of histoorgan mark, be stored in priority pair In should being related to.

Wherein, each histoorgan mark in the plurality of histoorgan mark can be the title of this histoorgan, volume Number etc., this is not limited by the embodiment of the present invention.In addition, each histoorgan mark includes organization identification or organ mark, also I.e., each histoorgan mark can be the mark etc. of the mark of tissue or organ, and the embodiment of the present invention is to this also Do not limit.Example, this histoorgan mark can be Organ naming, such as liver, pancreas, stomach etc. or organization name Claim, such as blood vessel, tumour etc..

In the embodiment of the present invention, in order to realize multiple organizers to two-dimensional medical images for the priority according to histoorgan Official carries out pseudo-colour display screen simultaneously and shows, before pseudo-colour display screen shows, it may be predetermined that multiple histoorgans identify, and it is many to be respectively provided with this The priority of each histoorgan mark in individual histoorgan mark, then by the plurality of histoorgan mark and corresponding priority It is stored in priority corresponding relation.

Wherein, the plurality of histoorgan mark can determine according to two-dimensional medical images, and i.e. the plurality of histoorgan identifies Can be the mark of histoorgan indicated by all or part of histoorgan image of display in two-dimensional medical images, certainly, The plurality of histoorgan mark also can determine according to the appointed part of human body or animal body, for example, when this appointed part is behaved During the abdominal cavity of body, the plurality of histoorgan mark can be the mark of all or part of histoorgan of human body abdominal cavity；Or Person, when this appointed part is whole human body, the plurality of histoorgan mark can be all or part of tissue of whole human body The mark etc. of organ, this is not limited by the embodiment of the present invention.

Wherein, in the plurality of histoorgan mark, the priority of each histoorgan mark is used for indicating this histoorgan mark Knowing the priority that the pseudo-colour display screen of corresponding histoorgan image shows, priority is higher, represents the corresponding tissue of this histoorgan mark Organic image is got over and can be shown by preferential pseudo-colour display screen.The priority of the plurality of histoorgan mark can be by terminal default setting, it is possible to With by user setup, and, the priority of the plurality of histoorgan mark can set according to the spatial relationship of histoorgan Put, it is also possible to be configured according to the criticality that operation route is formulated, or set according to the lesion degree of histoorgan Putting, this is not all limited by the embodiment of the present invention.

Wherein, this priority corresponding relation is specifically as follows tabular form, naturally it is also possible to store form for other, this This is not limited by bright embodiment.

Example, abdominal cavity includes multiple organ and multiple tissue, and the plurality of organ includes liver, pancreas, spleen, stomach etc., The plurality of tissue includes portal vein, vein, artery, inferior caval vein etc., be designated the title of histoorgan by histoorgan as a example by, Then this terminal can arrange the plurality of according to the criticality of the spatial relationship of abdominal cavity organ and tissue and clinical operation The priority of histoorgan mark, prioritization is as shown in table 1 below:

Table 1

Organization name or Organ naming	Priority
		Portal vein	1
Vein	2
		Artery	3
Inferior caval vein	4
		Tumour	5
Liver function section 0-liver function section 9	6-15
		Liver block mold	16
Pancreas	17
		Spleen	18
Stomach	19

It should be noted that, in upper table 1, the prioritization of organization name or Organ naming, more front, represents this organization name Claim or the priority of Organ naming is higher.In addition, liver function section 0-liver function section 9 therein is dividing of liver block mold Section part, that is to say, liver block mold can be divided into 9 functional sections, and be numbered this 9 functional sections respectively, To liver function section 0-liver function section 9, and according to upper table 1 it can be seen that number the priority of preceding liver function section Higher.

Step 102: determine that multiple histoorgan of the pixel position in two-dimensional medical images identifies.

Wherein, this two-dimensional medical images can be the two-dimensional medical images directly being obtained by Medical Imaging Technology, it is possible to Thinking the two-dimensional medical images obtaining during three-dimensional reconstruction, this is not limited by the embodiment of the present invention.

For example, this two-dimensional medical images can be for by CT, (Computed Tomography, electronic computer tomography is swept Retouch), the two dimension doctor that directly obtains of the Medical Imaging Technology such as MRI (Magnetic Resonance Imaging, magnetic resonance imaging) Learn image.

Again for example, owing to the three-dimensional reconstruction of medical image refers to demonstrate two-dimensional medical images information in three dimensions Come, specifically need the multiple two-dimensional medical images obtaining digital imaging technology to carry out three-dimensional reconstruction, just can such as be organized The three-dimensional medical model of organ etc., therefore, the two-dimensional medical images shown in the embodiment of the present invention can be 3 D medical model Certain original image, owing to each organ and the tissue contours of original image may be clear not, therefore can be at three-dimensional reconstruction During, according to the more accurate image information obtaining in three-dimensional medical model or in other two-dimensional medical images, to this Original image carries out supplementing and perfect so that each organ and tissue contours more clearly indicate, thus it is real to obtain the present invention Execute two-dimensional medical images pending in example.

Wherein, multiple histoorgan mark of this pixel position is for indicating the multiple tissues belonging to this pixel Organic image, that is to say, the plurality of histoorgan mark is exactly the group of the multiple histoorgan image instruction belonging to this pixel Knit the mark of organ.For example, if the liver organ image showing in two-dimensional medical images includes a tumor image, i.e. should Tumor image is shown on this liver image, then for each pixel on this tumor image, this pixel i.e. belongs to this liver Dirty image, falls within this tumor image, and therefore, multiple histoorgan mark of this pixel position includes liver organ mark Know and Neoplastic organ mark.

In addition, if the pixel in two-dimensional medical images only belongs to a histoorgan image, then this pixel institute is in place Put only corresponding histoorgan mark, and this histoorgan mark is the organizer of the corresponding highest priority of this pixel Official identifies；If the pixel in two-dimensional medical images is not belonging to any histoorgan image, then not corresponding any group of this pixel Knit organ mark, subsequent process shows without carrying out pseudo-colour display screen to this pixel.

In the embodiment of the present invention, image segmentation algorithm, each organizer being partitioned in two-dimensional medical images can be passed through Official's image, and according to segmentation result, determine that multiple histoorgan of the pixel position in this two-dimensional medical images identifies.

Specifically, it is determined that this pixel position multiple histoorgan mark process may include that based on this two Each histoorgan mark corresponding pre-set image partitioning algorithm respectively in dimension medical image, in this two-dimensional medical images Each histoorgan image is split, and obtains the segmentation image of this each histoorgan mark, and this each histoorgan identifies Segmentation image in the segmentation image of each histoorgan mark be used for indicating the corresponding pixel point set of this histoorgan mark Close；The segmentation image identifying according to this each histoorgan, determines multiple histoorgan mark of this pixel position.

Wherein, the corresponding pre-set image partitioning algorithm of each histoorgan mark, for referring to this histoorgan mark The histoorgan image showing splits from this two-dimensional medical images, obtains the contour images of this histoorgan, i.e. this tissue The segmentation image of organ mark.For example, it is possible to according to the corresponding default partitioning algorithm of liver organ, along liver organ image This liver organ image is split from this two-dimensional medical images, then splits the wheel of the liver organ obtaining by exterior contour Wide image is the segmentation image of liver organ.

It is additionally, since on the segmentation image of each histoorgan mark and includes the contour images of each histoorgan, then Each pixel in the contour images of this histoorgan belongs to this histoorgan mark, therefore, this histoorgan mark Segmentation image can serve to indicate that the corresponding pixel set of this histoorgan mark, also corresponds to each histoorgan mark Segmentation image stores this histoorgan and identifies and the corresponding pixel set with this histoorgan mark, and each histoorgan The segmentation image of mark also just stores each histoorgan mark respectively and identifies corresponding pixel with each histoorgan Set.

Therefore, according to each histoorgan identify segmentation image in storage corresponding relation, it is possible to inquire with often The corresponding histoorgan of individual pixel identifies.And, when a certain pixel corresponds only to a histoorgan mark, this organizer Official's mark is in two-dimensional medical images the histoorgan mark of this pixel position；When a certain pixel corresponds to multiple During histoorgan mark, the plurality of histoorgan mark is in two-dimensional medical images multiple tissues of this pixel position Organ identifies；When a certain pixel is not corresponding with any histoorgan mark, represent this pixel not at any organizer In the segmentation image of official, then in two-dimensional medical images the position of this pixel also not in any histoorgan image, after Also it is no need for carrying out pseudo-colour display screen to this pixel in this two-dimensional medical images during Xu to show.

Wherein, the corresponding pre-set image partitioning algorithm of each histoorgan mark can be by terminal default setting, it is also possible to By user setup, this is not limited by the embodiment of the present invention.

Step 103: from this priority corresponding relation, obtains each histoorgan mark in the plurality of histoorgan mark Priority, and according in the plurality of organ each histoorgan mark priority, from the plurality of histoorgan mark choosing Select the histoorgan mark of highest priority.

For example, the citing based on step 101, if this pixel position multiple histoorgan mark include pancreas and Spleen, then this terminal can obtain the priority of pancreas and the priority of spleen from above-mentioned table 1 respectively, owing to the prioritization of pancreas is 17, the prioritization of spleen is 18, therefore can show that highest priority histoorgan is designated pancreas.

It should be noted that embodiment is only with before step 102 during the present invention, set up according to the mode of step 101 One priority corresponding relation, and at step 104, according to the priority corresponding relation of step 101 foundation, from the plurality of tissue Illustrate as a example by the histoorgan mark selecting highest priority in organ mark, and in actual application, it is also possible to by it His mode selects the histoorgan mark of highest priority from the plurality of histoorgan mark, and this is not limited by the embodiment of the present invention Fixed.

Step 104: the histoorgan mark according to this highest priority, determines the color value of this pixel.

Wherein, to carry out this pixel when pseudo-colour display screen shows to this pixel for instruction to be shown for the color value of this pixel Color.

Wherein, the histoorgan mark according to this highest priority, determines the process of the color value of this pixel, can wrap Include any one in following manner:

In first kind of way, the color value of the histoorgan mark according to this highest priority, determine this pixel Color value.

Specifically, this terminal can be deposited in advance by the color value of multiple histoorgans mark and multiple histoorgans mark Storage, in organ color value corresponding relation, that is to say the corresponding relation pre-building histoorgan mark and color value, and stores This corresponding relation, then at step 104, this terminal can be searched with this priority from this organ color value corresponding relation The high corresponding color value of histoorgan mark, and the corresponding color value of histoorgan mark of this highest priority is defined as The color value of this pixel.

Wherein, the color value of each histoorgan mark can be by terminal default setting, it is also possible to by user setup, this This is not limited by bright embodiment.This organ color value corresponding relation can be tabular form or other storage forms, This is not also limited by the embodiment of the present invention.For example, it is assumed that histoorgan is designated the title of histoorgan, then example, liver The corresponding color value of internal organs official can be redness, and the corresponding color value of pancreas organ can be blueness, the corresponding face of spleen organ Colour can be yellow etc..

Further, this terminal can also identify at the histoorgan finding the corresponding highest priority of this pixel After color value, the color value of the histoorgan mark according to the corresponding highest priority of this pixel, generate this two-dimensional medical The pseudo-color mask array of image, the color mask array of this puppet is for storing the color value of each pixel in this two-dimensional medical images. Therefore, after covering color for this puppet mask array in this two-dimensional medical images, this terminal can according to this puppet coloured silk mask array, Determine the color value of this pixel, in order to the follow-up color value according to this pixel is to this pixel in this two-dimensional medical images Point carries out pseudo-colour display screen and shows.

In the second way, the mask coding of the histoorgan mark according to this highest priority, determine this pixel Color value.

Specifically, processing with machine language for the ease of terminal, this terminal can also be in advance by multiple histoorgans The mask coding of mark and the plurality of histoorgan mark, is stored in mask coding corresponding relation, wherein, and the plurality of organizer In official's mark, the mask coding of each histoorgan mark is used for indicating the corresponding color value of this histoorgan mark.In addition, should Terminal can also be stored in color value corresponding relation in advance by the color value of multiple masks coding and the plurality of mask coding. Then at step 104, this terminal can identify according to the histoorgan of this highest priority, encodes corresponding relation from this mask In, obtain the mask coding of the histoorgan mark of this highest priority, afterwards, further according to the histoorgan of this highest priority The mask coding of mark, from this color value corresponding relation, obtains the color value of the histoorgan mark of this highest priority, and The color value of the histoorgan of this highest priority is defined as the color value of this pixel.

Wherein, the color value of the mask coding of each organ, and each mask coding instruction can be set by terminal acquiescence Put, it is also possible to by user setup, this is not limited by the embodiment of the present invention.In addition, this mask coding corresponding relation and this color Value corresponding relation can be tabular form or other storage forms, and this is not also limited by the embodiment of the present invention.

Example, this terminal can be preset a byte and store each histoorgan mark corresponding mask coding, and covers Film coding can store in binary form, and owing to 1 byte is equal to 8 binary systems, then mask coding can include 2⁰ ～2⁸Totally 256 storage forms, that is to say, at most can store covering of 256 multi-forms in this mask coding corresponding relation Film encodes, and a mask coding is for one color value of instruction.For example, mask coding 0,000 0000 can indicate not do and locate Reason, mask coding 0,000 0001 can indicate redness, and mask coding etc. 0,000 0002 can indicate blueness etc..

In sum, in this implementation, this terminal can pre-build a histoorgan mark and mask coding Mapping table, and set up a mask coding and the mapping table of color value, determining this pixel position After the histoorgan mark of highest priority, histoorgan mark and the mapping table of mask coding can be inquired about, be somebody's turn to do The mask coding of the histoorgan mark of highest priority, then inquire about mask coding and the mapping table of color value, obtain with The corresponding color value of mask coding of the histoorgan mark of this highest priority, so that it is determined that go out the tissue of this highest priority The color value of organ mark, and the color value that this histoorgan identifies is defined as the color value of this pixel.

The memory space occupying due to color value is big, and the memory space that mask coding occupies is little, therefore, by setting up simultaneously Store the corresponding relation of each histoorgan mark and mask coding, the memory space of terminal can be saved, improve the fortune of terminal Row performance.

Further, this terminal can also identify at the histoorgan finding the corresponding highest priority of this pixel After mask coding, the mask coding of the histoorgan mark according to the corresponding highest priority of this pixel, generate this two dimension doctor Learning the mask array of image, this mask array is for storing the mask coding of each pixel in this two-dimensional medical images.Therefore, After covering this mask array in this two-dimensional medical images, this terminal can first determine this picture according to this mask array The mask coding of vegetarian refreshments, further according to the color value of mask this pixel of coding lookup of this pixel, in order to follow-up according to this picture The color value of vegetarian refreshments carries out pseudo-colour display screen and shows to this pixel in this two-dimensional medical images.

Specifically, the histoorgan mark according to this highest priority, determines that the process of the color value of this pixel is permissible Including: from mask coding mapping table, obtain the mask coding of the histoorgan mark of this highest priority, this priority The mask coding of histoorgan mark the highest is for indicating the color value of the histoorgan mark of this highest priority, this mask Each histoorgan mark being stored with in this two-dimensional medical images in coding mapping table and this each histoorgan mark Mask coding；The mask coding of the histoorgan mark according to the corresponding highest priority of this pixel, generates this two dimension doctor Learning the mask array of image, the mask array of this two-dimensional medical images is for storing each pixel in this two-dimensional medical images Mask coding；The mask coding of this pixel is obtained from this mask array；Mask coding according to this pixel, from color Value mapping table in, obtain the color value of this pixel, multiple mask that is stored with in this color value mapping table coding and The color value of the plurality of mask coding.

In this kind of mode, this pixel in whole two-dimensional medical images is being carried out before pseudo-colour display screen shows, can be with Mr. Become and this whole two-dimensional medical images corresponding mask array.Wherein, if the only corresponding histoorgan of a certain pixel identifies, Then in the mask array of this two-dimensional medical images, the mask coding of this pixel is the mask coding of this histoorgan mark；If A certain pixel identifies corresponding to multiple histoorgans, then need first to determine that the plurality of histoorgan mark medium priority is the highest Histoorgan mark, then inquire about the mask coding of the histoorgan mark of this highest priority, and this two-dimensional medical images In mask array, the mask coding of this pixel is the mask coding of the histoorgan mark of this highest priority；If a certain picture Vegetarian refreshments is not all corresponding with any histoorgan mark, then in the mask array of this two-dimensional medical images, the mask of this pixel encodes Can be for not carrying out the mask coding of any process to this pixel for instruction, for example, it is possible to be 0,000 0000 etc..

Further, determine the mask coding of this pixel in mask array according to machine language for the ease of terminal, should Terminal can also pre-build the corresponding relation of priority and mask coding, and stores this corresponding relation, in order to terminal is according to this The priority of the histoorgan mark of the corresponding highest priority of pixel, determines the mask coding of this pixel.

For example, it is assumed that the mask array of this whole two-dimensional medical images is the pel array of n × n, then corresponding mask is compiled Code can be designated as Mask (n, n), it is assumed that certain pixel corresponding histoorgan mark total number be m, then belonging to this pixel Histoorgan mark can be designated as t₀～t_m-1, and histoorgan mark t_iPriority can be designated as P (t_i), priority P Mask coding can be designated as M (P), then mask array i-th row of this whole two dimensional image, and the mask coding Mask of j row (j) may be used by i Think:

Mask (i, j)=M (max (P (t_i)) (1)

Wherein, max (P (t_i) represent multiple histoorgan mark t_iIt is preferential that medium priority histoorgan the highest identifies Level, M (max (P (t_i)) represent and max (P (t_i) corresponding mask coding, and mask array i-th row of this whole two dimensional image, j (i j) is equal to M (max (P (t to the mask coding Mask of row_i)).Wherein, with max (P (t_i) corresponding mask coding, Ke Yicong The above-mentioned priority pre-building and the corresponding relation of mask coding obtain.

In addition, obtain the i-th row in this mask array, j row mask coding Mask (i, j) after, can also be according to storage Color value corresponding relation, obtain with this mask array in the i-th row, j row mask coding Mask (i, j) corresponding color value, Example, with the i-th row in this mask array, (i, j) corresponding color value can be designated as C (Mask to the mask coding Mask of j row (i, j)).

Further, based on step 102, after the segmentation image obtaining each histoorgan mark, this terminal is all right The segmentation image identifying according to each histoorgan, generates the mask array of this two-dimensional medical images.Specifically, this terminal is permissible Inquire about the segmentation image of each histoorgan mark successively, obtain the corresponding pixel set of each histoorgan mark, and depend on The mask coding of secondary acquisition each histoorgan mark, thus according to the mask coding that each histoorgan identifies, be this two dimension This pixel aggregate assignment in the mask array of medical image.Wherein, during assignment successively, if this pixel set In certain pixel before not assignment, then directly the mask coding of this histoorgan mark can be defined as this pixel Mask coding；If certain pixel assignment in this pixel set, then also need to the mask of assignment before Encode corresponding histoorgan mark priority with currently will assignment histoorgan identify priority compare, if The priority of histoorgan mark before more than the priority of current histoorgan mark, then can be ignored and currently will compose The histoorgan mark corresponding mask coding of value, and before still retaining, the mask of assignment has encoded, if organizer before The mask coding of assignment less than the priority of current histoorgan mark, then can be replaced by the priority of official's mark Change, that is to say that replace with the mask of this pixel coding currently will the histoorgan mark corresponding mask coding of assignment.

It in this kind of mode, is coded into by the priority that identifies according to the histoorgan mask to pixel in mask array Row is replaced, and can realize that the mask coding by the histoorgan mark of corresponding for pixel highest priority is defined as this pixel Mask coding, and then realize that the color value by the histoorgan of corresponding for pixel highest priority mark is defined as this pixel The color value of point, in order to the color value of the histoorgan mark of follow-up follow-up highest priority carries out pseudo-colour display screen and shows to pixel, Thus the histoorgan image boundary that the repeatedly pseudo-color colour mixture avoiding a pixel causes obscures, and improves multiple organizer Official carries out the definition that pseudo-colour display screen shows simultaneously.

Step 105: according to the color value of this pixel, carries out pseudo-colour display screen and shows to this pixel.

Specifically, the color value according to this pixel, carries out the process that pseudo-colour display screen shows and may include that determination to this pixel The gray value of this pixel in two-dimensional medical images；Determine the pseudo-color transparency that pseudo-colour display screen shows；Color value according to this pixel, The gray value of this pixel and the color transparency of this puppet, carry out pseudo-colour display screen and show to this pixel.

Wherein, pseudo-color transparency is for indicating the transparency that color value shows, is used for guaranteeing originally to show with gray scale form Histoorgan identification information in the two-dimensional medical images shown is still high-visible after pseudo-colour display screen shows.The color transparency of this puppet is permissible By terminal default setting, it is also possible to by user setup, this is not limited by the embodiment of the present invention.

Wherein, pseudo-color transparency is bigger, and the transparency that color value shows is lower, and histoorgan identification information is more unclear Clear, it is therefore desirable to controlling the color transparency of this puppet can not be too big, original histoorgan identification information otherwise can be made invisible or Unintelligible, thus affect the degree of accuracy of diagnosis.Example, color for this puppet transparency can be set to 0.3,0.31 by this terminal Deng this is not limited by the embodiment of the present invention.

Wherein, carry out pseudo-colour display screen to this pixel to show, that is to say and the gray value of this pixel is multiplied by the first weight, and will The color value of this pixel is multiplied by the second weight, and by above-mentioned two product addition, thus obtain the final display of this pixel Value, it is achieved the colour mixture of color value and gray value.Wherein, the first weight is the difference of numerical value 1 color transparency with puppet, and the second weight is Pseudo-color transparency.

Example, it is assumed that this two-dimensional medical images is the pel array of n × n, then the i-th row, the gray value of jth row pixel Can be designated as IMG (i, j), the i-th row, the final show value of jth row pixel can be designated as DISP (i, j), the i-th row, jth row picture The color value of vegetarian refreshments can be designated as C (i, j), and pseudo-color transparency can be designated as α, then after Pseudo-color technology, this two-dimensional medical images In the i-th row, jth row pixel final show value DISP (i, j) be:

DISP (i, j)=(1-α) × IMG (i, j)+α × C (i, j) (2)

Wherein, when the corresponding multiple histoorgan mark of the pixel that this i-th row, jth arrange, this i-th row, jth row pixel Point color value C (i, j) be the corresponding highest priority of pixel histoorgan mark color value；When this i-th row, jth During the only corresponding histoorgan mark of the pixel of row, this histoorgan mark is the corresponding highest priority of this pixel Histoorgan mark, then this i-th row, jth row pixel color value C (i, j) be this histoorgan mark color value； When pixel only not corresponding any histoorgan mark that this i-th row, jth arrange, then without this pixel being carried out at pseudo-coloured silk Reason.

Further, based on above-mentioned steps 104, as the i-th row, jth row pixel corresponding color value C, (i, j) according in advance When the mask array first generating obtains, (i, (Mask (i, j)), correspondingly, in this two-dimensional medical images j) to be also denoted as C for this C I-th row, jth row pixel final show value DISP (i, j) can be:

DISP (i, j)=(1-α) × IMG (i, j)+α × C (Mask (i, j)) (3)

In actual application, in view of the dynamic range that pseudo-color transparency is limited, multiple for corresponding in two-dimensional medical images The pixel of histoorgan mark, if obtaining the corresponding face of each histoorgan mark in the plurality of histoorgan mark respectively Colour, and carry out pseudo-colour display screen to this pixel according to the plurality of color value respectively and show, that is to say the plurality of color value at this picture Carry out colour mixture on vegetarian refreshments, not only result in histoorgan identification information and show unintelligible, and multiple histoorgan can be caused pseudo- The color distinction of coloured picture picture is less, and boundary obscures, thus adds discrimination difficulty and the resolution duration of doctor, results even in doctor Raw erroneous judgement.And in the embodiment of the present invention, can be according to the space characteristic of each histoorgan and tissue, and in surgical guidance Criticality, carries out prioritization to multiple histoorgans mark, it is possible to according only to the tissue of corresponding highest priority The color value of organ, carries out pseudo-colour display screen and shows to the pixel in two-dimensional medical images, thus at the weight of multiple histoorgan images The histoorgan image of highest priority is also only carried out pseudo-colour display screen by folded region show, it is to avoid organ and organ, organ and group The blocking of pcolor picture between knitting or organizing and organize, such that it is able to do not affect key message complete on the premise of, according to The color value to overlapping region for the priority is accepted or rejected, so the image information in two-dimensional medical images accurately with simplify it Between achieve suitable balance.

In addition, during the present invention in embodiment, by setting the priority of multiple histoorgan mark, can also be in certain group The pcolor picture knitting organ mark increases or deletes the pcolor picture of a certain histoorgan mark or tissue.For example, in abdominal cavity In internal two-dimensional medical images, gallbladder tissue's image is generally comprised within liver organ image, when identify liver organ When priority is set greater than the priority of gallbladder tissue's mark, this two-dimensional medical images will only show the puppet of this liver organ Coloured picture picture, and when the priority that gallbladder tissue identifies is set greater than the priority of liver organ mark, this two-dimensional medical Image will preferentially show the pcolor picture of this gallbladder tissue, it is achieved thereby that add gall-bladder group on the pcolor picture of liver organ The pcolor picture knitted.Therefore, embodiments provide a kind of flexibly, can be with the tissue of self-defining two-dimensional medical images The pseudo-color display methods of organ, according to the method, user can eliminate neatly as desired or add a certain organ or tissue Pcolor picture.

In sum, in the embodiment of the present invention, can first determine that the pixel position in two-dimensional medical images is many Individual histoorgan identifies, more therefrom chooses the histoorgan mark of highest priority, and according to the organizer of this highest priority Official identifies, and determines the color value of this pixel, can carry out pseudo-colour display screen to this pixel according to the color value of this pixel afterwards Show.Wherein, the color value of the pixel identifying due to the corresponding multiple histoorgans in position, is all according to this pixel place The histoorgan mark of the highest priority of position determines, when therefore pseudo-colour display screen shows, this pixel is also according only to priority The color value of high histoorgan mark instruction carries out pseudo-colour display screen and shows, and the color value of not according to multiple histoorgan mark instruction Carry out pseudo-colour display screen respectively to show to this pixel, thus avoid the colour mixture of multiple color values in a pixel, and then avoid Between multiple organ or tissues, pcolor picture is overlapped, and display effect is succinct, clear, it is achieved that excellent according to histoorgan First level carries out pseudo-colour display screen simultaneously and shows to multiple histoorgans, and flexibility is high.
