Description

Mammary gland image file generation method and device and mammary gland image loading method and device

Technical Field

The application relates to the technical field of medical imaging, in particular to a mammary gland image file generation method and device and a mammary gland image loading method and device.

Background

With the continuous development of digital medical imaging technology and HTML5 technology, the development of domestic medical information construction, and medical imaging system based on B/S structure is becoming popular among doctors and patients. Among them, interpretation and diagnosis of mammary gland images are attracting attention as an important part thereof.

Typically, the breast image is scanned by an X-ray scanner and a DICOM sequence file is generated at the server according to the Digital Imaging and Communications in Medicine (DICOM) standard. When a doctor or a patient needs to browse the breast image, the network end (Web end) acquires the corresponding DICOM file from the server end, and renders and displays the DICOM file by using a front-end visualization technology means (e.g., canvas) so as to be browsed by the doctor or the patient.

However, the DICOM sequence file generated from the breast image has a large volume due to the high definition of the breast image, so that the network transmission process of the DICOM sequence file from the server to the Web is time-consuming. Moreover, the time required for loading the breast image on the Web end for the first time is long, and is usually longer than other types of images by more than 3 seconds, which seriously affects the user experience.

Moreover, since the download time and the display sequence of different breast images are different, a doctor can perform comprehensive diagnosis only by waiting for all the breast images to be displayed on the Web, so that the doctor needs to wait for a long time to see all the breast images from the Web, a large amount of waiting time is wasted, and user experience is seriously affected.

In order to improve user experience, the prior art provides a technical scheme, which specifically includes: in the process of loading the breast image by the Web end, the Web end performs preloading display by using a PNG (portable network generator) or JPG (joint photographic experts group) image generated by a server, and displays the breast image when the Web end finishes downloading the breast image required by a user.

Although the technical scheme can ensure that the Web end can rapidly display the image and avoid that the display interface of the Web end is always in a blank state, the displayed image is only a preset image and is not a breast image required by a user, and the Web end still needs to download a DICOM file corresponding to the breast image required by the user from the server end and perform rendering display on the Web end. Therefore, the technical scheme does not solve the problem that the DICOM file for downloading the breast images required by the user at the Web end is accelerated, the rendering and displaying speed at the Web end according to the DICOM file is not accelerated, and the downloading amount required by the Web end is increased due to the fact that preset PNG or JPG images need to be downloaded.

Detailed Description

As can be seen from the background section, the following technical problems still exist in the prior art:

due to the fact that the definition of the mammary gland image is high, the volume of a DICOM (digital imaging and communications in medicine) sequence file generated according to the mammary gland image is large, the transmission process of the DICOM sequence file is time-consuming, the time required for loading the mammary gland image by a Web end is long, and the mammary gland image cannot be displayed quickly; moreover, since the downloading sequence and the display sequence of different breast images are different, a doctor can perform comprehensive diagnosis only by waiting for all the breast images to be displayed on the Web terminal, so that the doctor needs to wait for a long time to see all the breast images from the Web terminal, a large amount of waiting time is wasted, and user experience is seriously influenced.

In the process of solving the technical problem, the present application finds, through research on breast images, that in each breast image, a breast area is generally located in an edge area, such as the left edge or the right edge, of the breast image. As an example, in the breast image shown in fig. 1, the breast area is located on the leftmost side of the breast image. In addition, since the breast area occupies only about half of the area in the breast image, the non-breast area (i.e., the blank area) occupies the other half of the area in the breast image; in addition, in the pixel data of the breast image, only the pixel data corresponding to the breast region has an analytical diagnostic value, and the pixel data corresponding to the non-breast region does not have an analytical diagnostic value, so that the pixel data having an analytical diagnostic value in the breast image is only about one-half of the total pixel data in the breast image.

The above contents are the characteristics of the breast image discovered by the inventor through studying the breast image, and based on the characteristics of the breast image, the application provides a breast image file generation method applied to a server side. Thus, the volume of the generated disassembled breast image file is much smaller than that of the original breast image file. Therefore, when the mammary gland image file is loaded on the Web end, the server end can send the disassembled mammary gland image file to the Web end, the time consumed by network transmission of the mammary gland image file is reduced compared with the time consumed by network transmission of an original mammary gland image file, and the download quantity of the Web end is reduced.

In order to make the technical solutions of the present application better understood, the following detailed description of the embodiments of the present application will be given with reference to the accompanying drawings in the embodiments of the present application for clear and complete description, and it is obvious that the described embodiments are only a part of the embodiments of the present application, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 2, it is a flowchart of a method for generating a breast image file according to an embodiment of the present application.

The method for generating the breast image file provided by the embodiment of the application comprises the following steps:

s201: and acquiring an original mammary gland image file, wherein the original mammary gland image file is a DICOM (digital imaging and communications in medicine) sequence file generated when the X-ray scanning equipment scans mammary glands.

The specific implementation of this step will be described in detail below.

S203: and searching pixel data of the mammary gland area from the pixel data of the original mammary gland image according to the orientation and the pixel row and column number of the original mammary gland image.

The specific implementation of this step will be described in detail below.

S205: and storing the file header of the original mammary gland image file and the pixel data of the mammary gland area as a new mammary gland image file.

The specific implementation of this step will be described in detail below.

In order to facilitate understanding and explanation of the generating method of the breast image file provided in the embodiment of the present application, the following describes specific implementation manners of S201, S203, S204, and S205 in sequence.

First, a specific embodiment of S201 will be described.

In S201, the original breast image file is a DICOM sequence file generated when the X-ray scanning device scans the breast, and in S201, the original breast image file may be obtained in real time by scanning the breast through the X-ray scanning device, or the stored original breast image file may be read from the storage space of the server.

For convenience of explanation and understanding of the acquisition process of the original breast image file, different embodiments of S201 will be described below with reference to the drawings.

Referring to fig. 3, the figure is a flowchart of an implementation manner of S201 provided in an embodiment of the present application.

As an embodiment, S201 may specifically be:

s2011: and the server receives a mammary gland image which is sent by the X-ray scanning equipment and obtained by scanning the mammary gland.

S2012: and the server side processes the mammary gland image according to the DICOM standard to generate an original mammary gland image file.

The original breast image file includes a file header and pixel data, and for convenience of explanation and understanding, the following description will be made with reference to fig. 4, where fig. 4 is a schematic structural diagram of the original breast image file provided in an embodiment of the present application.

Assuming that the breast image includes n pixel data, an original breast image file generated from the breast image is shown in fig. 4. In the original breast image file provided in fig. 4, the file header includes: the pixel row and column number of the original mammary gland image and the orientation of the original mammary gland image, and the pixel data comprises: pixel data 1 to pixel data n.

As an example, if the breast image includes 2816 × 2048 pixel points, the original breast image file shown in fig. 4 should include pixel data 1 through 2816 × 2048 pixel data.

A specific embodiment of S201 is introduced above, in which the breast image obtained by real-time scanning may be sent to the server side through the X-ray scanning device, so that the server side generates the original breast image file according to the DICOM standard. Thus, this embodiment enables processing of breast images obtained by real-time scanning.

In addition, the method for generating the breast image file provided by the embodiment of the application can process the breast image obtained by real-time scanning of the X-ray scanning device, and can also process the breast image stored in the storage space of the server, thereby expanding the application range of the method for generating the breast image file.

As another embodiment, S201 may specifically be: and the server side reads the mammary gland image from the first preset storage position and generates an original mammary gland image file according to the DICOM standard.

The first preset storage position can be preset or determined according to user requirements.

In addition, in order to further expand the application range of the method for generating a breast image file provided in the embodiment of the present application, the server may also directly read a stored original breast image file from the storage space, so as to process the stored original breast image file, and thus, the embodiment of the present application further provides another implementation manner, in which S201 may specifically be: and the server side reads the original breast image file from the second preset storage position.

The second preset storage position can be preset or determined according to user requirements.

In S201, the breast image obtained by real-time scanning by the X-ray scanning device may be received by the server, and the original breast image file is generated from the breast image according to the DICOM standard; the mammary gland image can also be read from the first preset storage position through the server, and the mammary gland image is generated into an original mammary gland image file according to the DICOM standard; and the original breast image file can be read from the second preset storage position through the server side. Therefore, the method for generating the breast image file provided by the embodiment of the application is not only suitable for processing the breast image obtained in real time, but also suitable for processing the stored breast image, and is also suitable for processing the stored original breast image file, so that the application range of the method for generating the breast image file is expanded.

A specific embodiment of S203 will be described below.

In S203, the pixel data may include an RGB value of each pixel, a gray scale value of each pixel, and an RGB value and a gray scale value of each pixel. For the sake of brevity, the following description will be made taking an example in which the pixel data includes a gradation value of each pixel.

Referring to fig. 5, the figure is a flowchart of an implementation manner of S203 provided in an embodiment of the present application.

As an embodiment, when the pixel data of the original breast image includes pixel grayscale values of each pixel of the original breast image, S203 may specifically be:

s203a 1: and traversing each pixel gray value of the original mammary gland image line by line from the image starting position close to the mammary gland region side according to the orientation of the original mammary gland image until the pixel line with each pixel gray value being 0 is traversed.

It should be noted that the orientation of the original breast image can be obtained from the file header of the parsed original breast image file, which can be used to represent the position information of the breast area in the breast image. For example, the orientation of the original breast image may indicate that the breast region is located at the far left or right of the breast image. According to the orientation of the element mammary gland image, the side of the image where the mammary gland area is positioned can be determined, and the starting position of the image can be determined.

The gray-scale value of the pixel ranges from 0 to 255. When the value is 0, a non-mammary gland region is indicated, and when the value is non-0, a mammary gland region is indicated.

Furthermore, the pixel data of the original breast image may be represented in the form of a pixel matrix. Let it be assumed that the original breast image is an m-row and n-column pixel image, and accordingly, the pixel data of the original breast image is a pixel matrix including m × n pixel gray values. Wherein m and n are positive integers.

As a specific example, if m is 5 and n is 7, the pixel data of the original breast image may be represented by a pixel matrix of 5 × 7, which may be, as a more specific example:

where F is used to represent the pixel matrix of the original breast image.

In addition, the value and position of each element in the pixel matrix F correspond to the pixel gray value and position of each pixel in the original breast image, and the specific correspondence relationship is as follows: the first column of the pixel matrix F is used to represent the leftmost column of pixel data in the original breast image, and the adjacent relationship between different columns in the pixel matrix F is the same as the adjacent relationship between different pixel columns in the original breast image; likewise, the first row of the pixel matrix F is used to represent the uppermost row of pixel data in the original breast image, and the adjacent relationship between different rows in the pixel matrix F is the same as the adjacent relationship between different rows of pixels in the original breast image.

In addition, based on the characteristics of the breast image, that is, the breast area is only concentrated on the left side or the right side of the whole breast image, therefore, the original breast image is split in order to improve the user experience. Specifically, the splitting needs to be performed from the line boundary of the breast region and the non-breast region of the original breast image. The line boundary of the breast region and the non-breast region refers to line pixel data located at the boundary of the breast region and the non-breast region when line-by-line traversal of the pixel data is performed in the breast image.

For convenience of understanding and explanation, the following explains and explains the line boundary between a breast region and a non-breast region in a breast image with reference to fig. 6, where fig. 6 is a schematic structural diagram of the line boundary in the breast image provided in the embodiment of the present application.

In the breast image shown in fig. 6, a line boundary divides the breast image into a left region and a right region in terms of pixel lines, wherein a breast region is located in the left region of the breast image, and a non-breast region is located in the right region of the breast image.

In addition, since each pixel column in the breast region includes pixel data related to the breast, so that at least one pixel gray value not equal to 0 exists in each corresponding pixel column in the breast region in the pixel matrix, but since each pixel column in the non-breast region does not include any pixel data related to the breast, so that each pixel gray value in each pixel column in the non-breast region in the pixel matrix is equal to 0, when determining the column boundary according to the pixel matrix corresponding to the breast image shown in fig. 6, the pixel column closest to the breast region and each pixel gray value being equal to 0 may be used as the column boundary between the breast region and the non-breast region in the breast image.

As a specific example, when the pixel data of the original breast image is the following pixel matrix F,

it can be determined that, in order from left to right, the first column, the second column and the third column of the matrix F are used to represent column pixel data corresponding to a breast area in a breast image, and the fourth column, the fifth column, the sixth column and the seventh column of the matrix F are used to represent column pixel data corresponding to a non-breast area (blank area) in the breast image, and in the embodiment of the present application, the fourth column pixel data closest to the breast area and having a gray value of 0 for each pixel may be used as a column boundary line, so as to subsequently determine the breast area of the breast image according to the column boundary line.

The above is the relevant content of the column boundary for distinguishing between breast regions and non-breast regions provided in the embodiments of the present application.

Based on the pixel data of the breast image provided above and the related content of the column boundary, the present application provides various embodiments of S203a1, which will be described in turn below.

As an embodiment, S203a1 may specifically be: according to the orientation of the original mammary gland image, traversing each pixel gray value of the pixel array row by row from the first pixel close to the mammary gland region side as a starting point until traversing to the pixel row of which each pixel gray value is 0.

Referring to fig. 7, this figure is a flowchart of an implementation manner of S203a1 according to this embodiment.

As an embodiment, when the pixel data of the original breast image is the pixel matrix F, then S203a1 may specifically be:

first, as can be seen from the orientation of the original breast image, the breast area is located in the left area of the breast image, and thus the image start position near the breast area side can be determined as the first column of the pixel matrix F.

Secondly, traversing the gray values of the pixels in the first column of the matrix F from the first pixel 10 of the first column close to the mammary gland region side as a starting point, and determining that the gray values of the pixels in the first column of the matrix F are not equal to 0, determining that the first column of the matrix F is not a column boundary line of the mammary gland region and the non-mammary gland region in the mammary gland image.

Secondly, traversing the gray values of all pixels in the second column of the matrix F, and determining that the gray values of all pixels in the second column of the matrix F are not equal to 0, determining that the second column of the matrix F is not a column boundary of the mammary gland region and the non-mammary gland region in the mammary gland image.

Second, traversing each pixel gray value in the third column of the matrix F and determining that there are pixel gray values in the third column of the matrix F that are not equal to 0, then determining that the third column of the matrix F is not the column boundary of the breast region and the non-breast region in the breast image.

Then, traversing each pixel gray value in the fourth column of the matrix F, and determining that each pixel gray value in the fourth column of the matrix F is 0, determining that the fourth column of the matrix F is a column boundary of the breast region and the non-breast region in the breast image.

The above provides a specific embodiment for determining the column boundary of the pixel matrix F, and thus, based on this embodiment, it can be seen that when the original breast image corresponds to the pixel matrix F with m rows and n columns_m×nAnd when the breast area is located on the left side of the original image, S203a1 may specifically be:

s203a 11: according to the orientation of the original mammary gland image, the mammary gland region is located in the left region of the mammary gland image, so that the image initial position close to the mammary gland region side can be determined as the pixel matrix F_m×nThe first column of (2).

S203a 12: traversing each pixel gray value in the pixel matrix F column by taking a first pixel in the first column as a starting point, determining whether each pixel gray value in a current traversal column of the pixel matrix F is equal to 0, and if so, determining that the current traversal pixel column is a column boundary; if not, the next row of pixel gray values is continuously traversed.

The above is a specific embodiment of S203a 1. In S203a1, the pixel data of the breast area may be acquired according to the line boundary by traversing each pixel gray value of the original breast image line by line from the image start position near the breast area side until the pixel line with each pixel gray value of 0 is traversed, and the pixel line with each pixel gray value of 0 is used as the line boundary of the breast area and the non-breast area in the breast image.

S203a 2: pixel data between the image start position near the breast area side and the previous one of the pixel rows for which the respective pixel gradation values are 0 is taken as pixel data of the breast area.

As an embodiment, when the pixel data of the original breast image is F, and it is determined that the image start position near the breast area side is the first column of the matrix F, and the fourth column of the matrix F is the column boundary between the breast area and the non-breast area in the breast image, then S203a2 may specifically be: pixel data between the first, second and third columns of the matrix F

As pixel data of the breast area.

The above provides an embodiment of S203, in which the pixel data between the image start position near the breast area side and the previous column of the pixel column as the column boundary of the breast area can be used as the pixel data of the breast area by traversing each pixel gray value of the original breast image column by column starting from the image start position near the breast area side so as to determine the pixel column where each pixel gray value is 0 and can be used as the column boundary of the breast area and the non-breast area in the breast image. As such, this embodiment can distinguish the pixel columns including the breast region from the pixel columns not including the breast region, so that the pixel data of the breast region can be acquired from the pixel columns including the breast region later.

In addition, since some blank area line pixel data may still be included in the line direction in the pixel data including the breast area obtained in the foregoing embodiment, in order to further reduce the content of the blank area pixel data in the obtained pixel data including the breast area, and further reduce the volume of a new breast image file, the present embodiment further provides another embodiment of S203, which will be explained and explained below with reference to the drawings.

Referring to fig. 8, which is a flowchart of another implementation manner of S203 provided in this application example.

S203B 1: and traversing each pixel gray value of the original mammary gland image line by line from the image starting position close to the mammary gland region side according to the orientation of the original mammary gland image until the pixel line with each pixel gray value being 0 is traversed.

The embodiment of S203B1 is the same as the embodiment of S203A1 and, for the sake of brevity, is not set forth herein.

S203B 2: according to the orientation of the original mammary gland image, pixel gray values of the original mammary gland image are traversed line by line from an image starting position close to the mammary gland region side until pixel rows with all pixel gray values being 0 are traversed.

In some practical application scenarios, the breast area may only occupy the upper left area, the lower left area, the upper right area or the lower right area of the original breast image, and at this time, only the blank area on the left side or the right side of the breast area can be removed through the step S203B1, but the blank area above or below the breast area cannot be removed.

In order to specifically explain and understand the structure of the original breast image, the following description is made with reference to fig. 9, where fig. 9 is a schematic structural diagram of a boundary line in the breast image provided in the embodiment of the present application.

In the breast image shown in fig. 9, the breast area is located in the upper left region of the breast image, and the breast image specifically includes: a breast region, a first non-breast region and a second non-breast region, wherein the first non-breast region and the second non-breast region together form the non-breast region of the breast image, and wherein the breast region and the first non-breast region can be distinguished by a column boundary and the breast region and the second non-breast region can be distinguished by a row boundary.

In the breast image shown in fig. 9, a column boundary divides the breast image into a left region and a right region in terms of pixel columns, wherein the breast region is located in the left region of the breast image, and the first non-breast region is located in the right region of the breast image. In addition, since each pixel column in the breast region includes pixel data related to the breast, so that a pixel gray value different from 0 exists in each pixel column in the breast region, but each pixel column in the first non-breast region does not include any pixel data related to the breast, so that each pixel gray value in each pixel column in the first non-breast region is 0, when determining a column boundary according to the pixel matrix corresponding to the breast image shown in fig. 9, a pixel column closest to the breast region and having each pixel gray value of 0 may be used as the column boundary between the breast region and the first non-breast region in the breast image.

In addition, a line boundary divides the breast image into an upper region and a lower region by pixel lines, wherein the breast region is located in the upper region of the breast image and the second non-breast region is located in the lower region of the breast image. In addition, since each pixel row in the breast region includes pixel data related to the breast, so that a pixel gray value different from 0 exists in each pixel row in the breast region, but each pixel row in the second non-breast region does not include any pixel data related to the breast, so that each pixel gray value in each pixel row in the second non-breast region is 0, when a row boundary is determined according to the pixel matrix corresponding to the breast image shown in fig. 9, the pixel row closest to the breast region and having each pixel gray value of 0 may be used as the row boundary between the breast region and the second non-breast region in the breast image.

Based on the image described in fig. 9, as a specific example, when the pixel data of the original breast image is

When the temperature of the water is higher than the set temperature,

it can be determined that the fourth column of the pixel matrix F is a column boundary and the sixth row is a row boundary.

As is apparent from the structure of the original breast image provided above, when the pixel columns each having a gray level of 0 obtained by performing S203B1 can be taken as the column boundary and the pixel rows each having a gray level of 0 obtained by performing S203B2 can be taken as the row boundary, the non-breast region and the breast region of the breast image can be determined more accurately from the column boundary and the row boundary, so that the content of the pixel data of the hollow white region in the obtained pixel columns including the breast region can be further reduced.

S203B 3: pixel data between the image start position near the breast area side, the previous column of the pixel column for which each pixel gradation value is 0, and the previous row of the pixel row for which each pixel gradation value is 0 are taken as pixel data of the breast area.

It should be noted that there is no fixed execution sequence between S203B1 and S203B2, S203B1 and S203B2 may be executed in sequence, S203B2 and S203B1 may be executed in sequence, and S203B1 and S203B2 may be executed simultaneously.

In the above embodiment of S203, the pixel data between the previous row of the pixel column with the gray value of 0 and the previous row of the pixel row with the gray value of 0 at the image start position near the breast area side may be used as the pixel data of the breast area by traversing the gray values of the pixels of the original breast image from the image start position near the breast area side to the pixel column with the gray value of 0, and then traversing the gray values of the pixels of the original breast image from the pixel row with the gray value of 0 to the pixel row with the gray value of 0. In this way, in the traversal process, each pixel gray value encountered for the first time is 0 pixel column as a column boundary between the breast region and the non-breast region in the breast image, and each pixel gray value traversed for the first time is 0 pixel row as a row boundary between the breast region and the non-breast region in the breast image, so as to determine the pixel data of the breast region according to the column boundary, the row boundary and the image start position close to the breast region side.

In the above-provided embodiment of S203, the boundary may be determined by traversing from the starting position of the image close to the breast area side, and in addition, the embodiment of the present application may also determine the boundary by traversing from the starting position of the image far from the breast area side, so that the embodiment of the present application also provides another embodiment of S203, which will be explained and explained below with reference to the drawings.

Referring to fig. 10, it is a flowchart of another implementation manner of S203 provided in this application.

As another embodiment, S203 may specifically be:

S203C 1: according to the orientation of the original mammary gland image, starting from the image starting position far away from the mammary gland region side, traversing each pixel gray value of the original mammary gland image line by line until traversing to the pixel line of which each pixel gray value is not 0.

The pixel column with the gray value of each pixel different from 0 refers to the pixel column with the gray value of each pixel different from 0 which is encountered for the first time in the traversal process, and the pixel column can be used as a column boundary of a mammary gland region and a non-mammary gland region in a mammary gland image.

For ease of understanding and explanation of S203C1, the following description will be given taking as an example an original breast image comprising m rows and n columns of pixels. Wherein m and n are positive integers.

As an embodiment, when the original breast image is an m-row and n-column pixel image, and accordingly, the pixel data of the original breast image is a pixel array including m × n pixel gray scale values, S203C1 may specifically be: according to the orientation of the original mammary gland image, traversing each pixel gray value of the pixel array row by row from the first pixel far away from the mammary gland region side as a starting point until traversing to the pixel row of which each pixel gray value is 0.

For ease of understanding and explanation of this embodiment, the original breast image represented by a 5 × 7 matrix will be described below with reference to fig. 11 as an example.

Referring to fig. 11, this figure is a flowchart of an implementation manner of S203C1 according to an embodiment of the present application.

As an example, when the pixel data of the original breast image is F, S203C1 may specifically be:

S203C 11: according to the position of the original mammary gland image, the image starting position far away from the mammary gland region side is determined to be the seventh column of the pixel matrix F.

S203C 12: traversing each pixel gray value in the pixel matrix F column by taking the first pixel 0 of the seventh column as a starting point, determining whether each pixel gray value in each column of the pixel matrix F is equal to 0, and if so, continuously traversing the next column of pixel gray values; if not, determining that the pixel column traversed currently is a column boundary.

The above is a specific embodiment of S203C 1. In S203C1, the pixel data of the breast region may be acquired according to the line boundary by traversing each pixel gray value of the original breast image line by line from the image start position far from the breast region side until the pixel line where each pixel gray value is not 0 is traversed, and the pixel line is used as the line boundary of the breast region and the non-breast region in the breast image.

S203C 2: pixel data between the image start position near the breast area side and the pixel column in which the respective pixel gradation values are not all 0 is taken as pixel data of the breast area.

As an embodiment, when the pixel data of the original breast image is F, the image starting position far from the breast area side may be determined to be the seventh column of the matrix F, and the third column of the matrix F is determined to be a column boundary line between the breast area and the non-breast area in the breast image, then S203C2 may specifically be: the pixel data between the first column of the matrix F and the third column of the matrix F is taken as the pixel data of the mammary gland region.

The above provides an embodiment of S203, in which the pixel data between the image start position close to the breast area side and the pixel column as the column boundary of the breast area and the non-breast area in the breast image can be used as the pixel data of the breast area by traversing each pixel gray scale value of the original breast image column by column starting from the image start position far from the breast area side so as to determine the pixel column where each pixel gray scale value is not 0 and can be used as the column boundary of the breast area and the non-breast area in the breast image. As such, this embodiment can distinguish the pixel columns including the breast region from the pixel columns not including the breast region, so that the pixel data of the breast region can be acquired from the pixel columns including the breast region later.

In addition, since the pixel array including the breast area obtained in the foregoing embodiment still includes some pixel data of blank areas, in order to further reduce the content of the pixel data of blank areas in the obtained pixel array including the breast area, another embodiment of S203 is provided in the embodiments of the present application, which will be explained and explained below with reference to the drawings.

Referring to fig. 12, it is a flowchart of another implementation manner of S203 provided in this application.

As another embodiment, S203 may specifically be:

S203D 1: according to the orientation of the original mammary gland image, starting from the image starting position far away from the mammary gland region side, traversing each pixel gray value of the original mammary gland image line by line until traversing to the pixel line of which each pixel gray value is not 0.

The embodiment of S203D1 is the same as the embodiment of S203C1, and for brevity, is not repeated here.

S203D 2: according to the orientation of the original mammary gland image, pixel gray values of the original mammary gland image are traversed line by line from an image starting position far away from the mammary gland region side until pixel rows with the gray values of all pixels different from 0 are traversed.

The pixel row with the gray value of each pixel different from 0 refers to the pixel row with the gray value of each pixel different from 0 encountered for the first time in the traversal process, and the pixel row can be used as a row boundary line of a mammary gland region and a non-mammary gland region in a mammary gland image.

When the pixel columns of which the respective pixel gradation values obtained by performing S203D1 are not all 0 can be taken as the column boundary and the pixel rows of which the respective pixel gradation values obtained by performing S203D2 are not all 0 can be taken as the row boundary, the non-breast region and the breast region of the breast image can be determined more accurately from the column boundary and the row boundary, so that the content of the pixel data of the obtained hollow white region in the pixel columns including the breast region can be further reduced.

S203D 3: and taking pixel data between an image starting position close to the mammary gland region side, a pixel column with each pixel gray value different from 0 and a pixel row with each pixel gray value different from 0 as the pixel data of the mammary gland region.

It should be noted that, in the embodiment of the present application, the S203D1 and the S203D2 have no fixed execution sequence, and may execute the S203D1 and the S203D2 in sequence, may execute the S203D2 and the S203D1 in sequence, and may execute the S203D1 and the S203D2 at the same time.

In the above-mentioned embodiment of S203, the pixel data between the pixel columns with the gray values being not 0 and the pixel rows with the gray values being not 0 near the image start position near the breast area side and between the pixel columns with the gray values being not 0 and the pixel rows with the gray values being not 0 may be used as the pixel data of the breast area by traversing the pixel gray values of the pixels of the original breast image column by column from the image start position far from the breast area side until the pixel columns with the gray values being not 0 are traversed, and then traversing the pixel gray values of the pixels of the original breast image row by row until the pixel rows with the gray values being not 0 are traversed. In this way, in the traversal process, the line where the gray values of the pixels encountered for the first time are not all 0 pixel can be used as the line boundary between the breast area and the non-breast area in the breast image, and the line where the gray values of the pixels encountered for the first time are not all 0 pixel can be used as the line boundary between the breast area and the non-breast area in the breast image, so as to determine the pixel data of the breast area according to the line boundary, the line boundary and the image start position near the breast area side.

In S203, according to the position and the number of rows and columns of pixels of the original breast image, pixel data of a breast area may be searched from the pixel data of the original breast image, so as to generate a new breast image file according to the pixel data of the breast area in the following step.

A specific embodiment of S204 is described below.

As an embodiment, when the breast region includes N pixel data: when the 1 st pixel data, the second pixel data, … …, and the nth pixel data are included, S204 may specifically be: according to the positions of the 1 st pixel to the Nth pixel in the original mammary gland image file, respectively obtaining the pixel data of the 1 st pixel to the Nth pixel from the pixel data of the original mammary gland image, and taking the pixel data of the 1 st pixel to the Nth pixel as the pixel data of the mammary gland area.

As an example, when the pixel data of the original breast image is a pixel matrix F of 5 × 7, it is determined that 15 pixel data are included in the breast region after S203

When the temperature of the water is higher than the set temperature,

s204 may specifically be: determining the positions of the 1 st pixel to the 15 th pixel in the original mammary gland image file according to the step S203, respectively acquiring the pixel data of the 1 st pixel to the 15 th pixel from the pixel data of the original mammary gland image, and taking the pixel data of the 1 st pixel to the 15 th pixel as the pixel data of the mammary gland region.

In this way, the number of pixels can be reduced from 5 × 7 to 35 pixels in the original breast image to 5 × 3 to 15 pixels including the breast region, and the number of pixel data can be effectively reduced, thereby reducing the volume of the new breast image file obtained from the 15 pixels including the breast region.

In S203, the pixel data of the breast area may be extracted from the pixel data of the original breast image according to the position order of each pixel in the original breast image file.

A specific embodiment of S205 is described below.

As an embodiment, S205 may specifically be: according to the DICOM standard, a file header of an original breast image file is used as a file header of a new breast image file, and pixel data of a breast area is used as pixel data of the new breast image file.

In this way, the new breast image file includes both the orientation and the pixel row and column number of the original breast image and the pixel data of the breast area. At this time, since the pixel data of the breast area is much smaller than that of the original breast image, the volume of the new breast image file is much smaller than that of the original breast image, so that the transmission data volume of the breast image file is reduced, and the transmission speed of the breast image file is further improved.

In S205, the file header of the original breast image file and the pixel data of the breast area are stored as a new breast image file.

In this embodiment, based on the characteristics of the breast image, that is, the breast area only occupies a partial area of the original breast image, the original breast image file is disassembled, that is, the pixel data of the breast area is extracted from the original breast image file, and then the disassembled breast image file is generated according to the extracted pixel data of the breast area. Thus, the volume of the generated disassembled breast image file is much smaller than that of the original breast image file. Therefore, when the mammary gland image file is loaded on the Web end, the server end can send the disassembled mammary gland image file to the Web end, the time consumed by network transmission of the mammary gland image file is reduced compared with the time consumed by network transmission of an original mammary gland image file, and the download quantity of the Web end is reduced.

The first method embodiment provides a method for generating a breast image file, in which pixel data of a breast area is split from an original breast image file, and a new breast image file is generated according to the pixel data of the breast area, so as to reduce the volume of the breast image file, reduce the transmission data volume of the breast image file, and further improve the transmission speed of the breast image file.

In addition, in order to display a new breast image file on a Web end, the application also provides a loading method of the breast image, which will be explained and explained below with reference to the drawings.

Method embodiment two

Referring to fig. 13, it is a flowchart of a breast image loading method provided in the second embodiment of the present application.

The mammary gland image loading method provided by the embodiment of the application comprises the following steps:

s1301: and the Web end sends a request for acquiring the breast image file to the server end.

S1302: and the Web end receives the breast image file returned by the server end.

The step may specifically be: after the server receives the request for acquiring the breast image file sent by the Web, the server returns the breast image file newly generated according to the method embodiment to the Web, so that the Web can receive the breast image file returned by the server.

The volume of the mammary gland image file is smaller than that of the original mammary gland image file, so that the transmission time of the mammary gland image file from the server to the Web end is reduced, the data volume of the mammary gland image file received by the Web end from the server is reduced, the speed of receiving the mammary gland image file by the Web end from the server is increased, the waiting time required by the Web end for displaying the mammary gland image is reduced, and the user experience is improved.

S1303: and the Web terminal analyzes the mammary gland image file according to the DICOM standard to obtain a file header and pixel data of the mammary gland image file.

It should be noted that the file header of the parsed breast image file includes the pixel row and column number and the image orientation of the original breast image corresponding to the breast image file.

S1304: and the Web end sets the gray value of each pixel in the visible area of the Web end to be 0 according to the number of pixel rows and columns of the original mammary gland image.

As an embodiment, as shown in fig. 14, when the original breast image is an m-row and n-column pixel image, S1304 may specifically be: and the Web end sets the gray value of each pixel in the m rows and n columns of pixels in the visible area of the Web end to be 0 according to the number m and the number n of the rows of the pixels of the original mammary gland image.

S1305: and the Web end performs covering rendering on the pixel gray value of each pixel of the mammary gland image file from the initial position of the visible area close to the mammary gland area side according to the direction of the original mammary gland image.

As an embodiment, as shown in fig. 15, S1305 may specifically be: the Web side performs rendering by overlaying the pixel gray values of the pixels of the breast image file from the initial position of the visible area near the breast area side by using a front-end visualization technical means (e.g., canvas) according to the orientation of the original breast image.

For convenience of explanation and explanation, the breast region including the pixel image of i rows × j columns will be described as an example, where i is less than m, i is less than n, and i and j are positive integers.

Let it be assumed that the breast region is i rows x j columns of pixels, and accordingly, the pixel data of the breast image file is a pixel matrix including i x j pixel gray scale values.

As an embodiment, S1306 may specifically be: according to the azimuth of the original mammary gland image, coverage rendering is carried out on the visual area by adopting pixel gray values in the pixel array according to row sequencing from the first pixel close to the mammary gland area side as a starting point, wherein the row is changed after j pixels are rendered until i rows are rendered.

As another embodiment, S1305 may specifically be: according to the azimuth of the original mammary gland image, coverage rendering is carried out on the visual area by adopting pixel gray values in the pixel array according to column sequencing from the first pixel close to the mammary gland area side as a starting point, wherein the rendering is carried out in a column-changing manner after i pixels are rendered until j columns.

In the embodiment, because the breast image file obtained by the Web end is only used for recording the pixel data of the breast area, and the pixel data of the breast area is only part of the pixel data in the original image, the volume of the breast image file obtained by the Web end is much smaller than that of the original breast image file, so that the downloading amount of the Web end for obtaining the breast image file from the server end is reduced, the efficiency of the Web end for obtaining the breast image file from the server end is improved, and the user experience is further improved. In addition, because the Web end carries out rendering display according to the mammary gland image file, and the pixel data volume recorded in the mammary gland image file obtained by the Web end is much less than the pixel data volume recorded in the original mammary gland image file, the pixel data required to be rendered by the Web end is less, the rendering display efficiency of the Web end can be improved, the time required for displaying the mammary gland image by the Web end can be reduced, and the user experience is further improved.

and the pixel data between the image start position near the breast area side, the previous column of the pixel column of which each pixel gray value is 0, and the previous row of the pixel row of which each pixel gray value is 0 are used as the pixel data of the breast area.

As an implementation manner, in order to further reduce the data volume of the breast image file, so as to improve the transmission efficiency of the breast image file, and further optimize the user experience, the original breast image is an m-row n-column pixel image, and correspondingly, the pixel data of the original breast image is a pixel array including m × n pixel gray values, where m and n are positive integers;
