Detailed Description

For the purpose of better explaining the present disclosure, and to facilitate understanding thereof, the present disclosure will be described in detail below by way of specific embodiments with reference to the accompanying drawings.

All technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein in the description of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Based on the prior art, in the DICOM browsing process, when the currently browsed DCIOM image is to be saved and output, only the current screenshot of the window can be saved, and the description information displayed in the image window cannot be modified in content and relative size, but when the image is output in a printing function or in a report form, the size of the description information usually needs to be changed, even if an interpolation algorithm is used for processing, local deformation of the image inevitably occurs, and the analysis and diagnosis result of a doctor is influenced. Therefore, the present invention provides a method and a device for processing DICOM data, which are described in detail as follows:

fig. 1 is a flowchart of a method for processing DICOM data according to an embodiment of the present disclosure, as shown in fig. 1, specifically including the following steps:

as shown in fig. 1, in step S110, DICOM data displayed in a current window and a base view angle of the window are acquired, where the DICOM data includes a DICOM image and description information;

as shown in fig. 1, in step S120, the description information in the DICOM data is segmented to obtain at least one local image corresponding to the description information;

as shown in fig. 1, in step S130, performing multi-plane reconstruction on the DICOM image according to the basic view angle and a preset transformation relationship to obtain a two-dimensional image;

as shown in fig. 1, in step S140, performing scaling adjustment on the local image according to a preset scaling ratio to obtain an adjusted local image;

as shown in fig. 1, in step S150, the two-dimensional image and the adjusted local image are rendered and displayed in a virtual window according to relative positions, and an image displayed in the virtual window is output.

The specific implementation of the steps of the embodiment of fig. 1 is described in detail below:

in step S110, the DICOM data displayed in the current window and the base view angle of the window are acquired.

In an embodiment of the disclosure, the DICOM data includes a DICOM image and description information, where the description information is mainly used for storing information related to a medical image. After loading the DICOM data in this step, the method further includes: and acquiring a volume data set formed by pixel points in all DICOM images, wherein the volume data set comprises space coordinates from the first DICOM image to the center position of the first pixel at the upper left corner, the volume data size and the volume data number.

For example, the browsing software loads the local DICOM data by selecting a folder. The DICOM data are loaded, the DICOM images are analyzed in the loading process, and three-dimensional space information of the DICOM image volume data set is stored. Because the volume data is usually obtained by scanning with an instrument such as a CT and the like and then stored in pixel points of a picture, the volume data is composed of voxels, the voxels are basic volume elements, and the three-dimensional space information of the volume data set is the arrangement information and color information of the voxels in the three-dimensional space. Fig. 2 is a schematic diagram of an image displayed in the window in step S110 according to an embodiment of the present invention.

In addition, since the DICOM image is displayed in the window, the current view angle of the window is used as the basic view angle, and the subsequent view angle transformation is changed by using the current basic view angle as the original angle.

In step S120, the description information in the DICOM data is segmented to obtain at least one local image corresponding to the description information.

In an embodiment of the present disclosure, the description information needs to be segmented from the DICOM image in this step, where the relative position of the description information and the DICOM image may be: the left upper part, the upper right part, the right upper part, the right lower part, the lower left part and the left part are 8 different directions. When in segmentation, segmentation can be carried out on the basis of the image, namely, the description information in the DICOM data is segmented according to the relative position with the DICOM image; then, the description information block in the divided relative orientation is used as a local image.

In an embodiment of the present disclosure, after the dividing, it is further required to determine how to define the size of each description information tile, so that after obtaining at least one local image corresponding to the description information, the method further includes: calculating the width and height occupied by the description information of 8 directions positioned at the periphery and four corners of the DICOM image window, wherein the width and the height are all in pixel unit.

Because description information is divided into a plurality of cases, some cases are one line of characters, and some cases are multiple lines of characters, when the description information image block comprises one line of characters, the pixel height of the characters is taken as the height of a local image, and the pixel length of the characters is taken as the width of the local image; when the description information image block comprises a plurality of lines of characters, the pixel height of the characters is taken as the height of the local image, and the maximum value of the pixel length of the plurality of lines of characters is taken as the width of the local image.

Based on the above, the tile is used as the width and height of the partial image according to the determined width and height as the segmentation description information, and the pixel values of the width and height are used as the original scaling.

In step S130, performing multi-plane reconstruction on the DICOM image according to the basic view angle and a preset transformation relation, so as to obtain a two-dimensional image.

In an embodiment of the present disclosure, the multi-plane reconstruction performed in this step includes at least one of scaling, translation, rotation, and window width and level adjustment.

In an embodiment of the present disclosure, the method further includes:

Because the window width refers to the CT value range displayed by the CT image, the width of the window width directly influences the definition and the contrast of the image, and the narrower the window width is, the smaller the displayed CT value range is, the stronger the contrast is, and the method is suitable for observing the tissue structure with closer density; conversely, the wider the window width, the larger the displayed CT value range, and the poorer the contrast, the more suitable for observing tissue structures with larger density differences. The window level (window center) refers to an average value or a center value within a window width range, so if the window width and the window level are adjusted once, the color of the DICOM image must also change accordingly, and therefore, the adjusted window width and the window level need to be recorded in this step, so as to record the color.

In step S140, the local image is scaled according to a preset scaling ratio, so as to obtain an adjusted local image.

In an embodiment of the present disclosure, since in the prior art, when the currently browsed DCIOM image is to be saved and output during DICOM browsing, only the current screenshot of the window can be saved, and the saved image can be used for a printing function or output in a report form. However, the image saved in this way is in a what-you-see-what-you-get form, the size of the image is determined according to the size of the window, the size of the displayed image cannot be modified, if the image size is forcibly zoomed, the image needs to be processed by using an interpolation algorithm, so that local deformation of the image is inevitably generated, and the analysis and diagnosis result of a doctor is influenced. Based on the above problem, the local image and the DICOM image are segmented based on the above steps, and the size of the segmented local image can be adjusted according to a preset scaling ratio, so that the adjusted local image (for example, information such as orientation information and patient name) can not be scaled in proportion to the DICOM image, thereby reducing the occlusion of the local image on the image and reducing the visible range of non-important information.

Further, since the segmented local images in this embodiment usually represent different types of description information, when the preset scaling is set, the scaling with the same or different size may be set for different local images according to requirements.

In step S150, the two-dimensional image and the adjusted local image are rendered and displayed in a virtual window according to the relative position, and an image displayed in the virtual window is output.

Fig. 3 is a flowchart of step S150 in an embodiment of the present invention, which specifically includes the following steps:

in step S301, a virtual window is created, wherein the size of the virtual window is the same as the size of the image to be output.

In step S302, the volume data set is added to the virtual window as display data.

In step S303, a corresponding camera angle is set for the display data according to the basic angle and the preset transformation relationship.

In step S304, a window texture is drawn in the virtual window according to the camera angle in combination with the display data, so as to obtain the two-dimensional image.

Based on the steps, a projection relation is established according to a three-dimensional space projection principle in computer graphics, and a reconstruction method of multi-planar reconstruction (MPR for short) is used. The MPR can superpose all axial images in a scanning range, and then carry out coronal, sagittal and any-angle oblique image reconstruction on tissues appointed by reconstruction lines marked by certain marked lines, can randomly generate new tomographic images without repeated scanning, and can expand and display the growth of a curved object in one image if curved surface reconstruction is adopted. When the size of the output image needs to be Width pixels and Height pixels, the position information, the view angle information, the scaling relation and the like of the image are utilized to calculate all pixel values of Width multiplied by Height pixels in the DICOM image actually corresponding to the output image, color mapping information is set for the pixel values, and the processed pixel set can form a two-dimensional image

rendering and displaying the image of the virtual window after being drawn.

Based on the above, taking the image shown in fig. 2 as an example, fig. 4 is a specific flowchart for processing DICOM data by combining the image shown in fig. 2, and includes the following steps:

step S1, the browsing software loads DICOM data.

And step S2, acquiring DICOM data three-dimensional information.

And step S3, displaying the DICOM data and acquiring a basic visual angle.

Next, the window image is transformed, mainly by dividing the DICOM image and the description information, and then processed separately.

Step S4, an image conversion operation is performed.

The operations of zooming, translation, rotation, window width and window level adjustment and the like can be carried out on the image in the window. After the above operations are performed, the content of the data displayed in the window is changed, and operations such as zooming, translating, rotating and the like are performed on the image, so that the view angle of the window is changed, that is, the operations change the relative position of the image and the viewpoint for viewing the image. And recording a relative coordinate transformation relation Matrix of the changed viewpoint and the image.

In this step, taking the translation operation as an example: setting the coordinate of a pixel A in a three-dimensional space as (X, Y, Z), performing translation on the pixel point, translating the pixel point by a units in the X direction, translating the pixel point by b units in the Y direction, translating the pixel point by c units in the Z direction, and setting the new coordinate of the pixel A after the translation as (X, Y, Z)₁,Y₁,Z₁)：

According to the three-dimensional space transformation rule, multiplying all the transformations by steps to obtain a total transformation matrix: a Matrix transformation relation Matrix is a translation Matrix and a scaling Matrix and a rotation Matrix; the Matrix transformation Matrix is a relative coordinate transformation relation Matrix of the viewpoint and the image, wherein one or more of translation, scaling and rotation can be selected.

And step S5, acquiring the size of the description information picture block.

And step S6, setting DICOM image output parameters.

In this step, based on the data saving operations in steps S4 and S5, the saving output parameters, such as the name of the generated DICOM image, the length of the DICOM image, the wide pixel value, the scaling percentage value of the image description information, the DICOM image saving path, and other related information, can be set through the operation interface of the software.

Next, the DICOM image (steps S7 and S8) and the description information are still processed separately (steps S9 and S10), as follows:

step S7, create a virtual window and set the window size.

In which a virtual window is set according to the parameters set at S6.

And step S8, setting display data.

And setting a volume data set formed by pixel points of the DICOM image into a window as display data, and recording a coordinate transformation matrix of the current window and position information of the current image.

And creating a virtual OpenGL window, setting the window size to be consistent with the size of the stored image, setting a volume data set formed by pixel points of the DICOM image into the window as display data, and setting the view angle of the camera by using the recorded viewpoint and the transformation matrix of the image.

Fig. 5 is a schematic diagram of display data obtained in an embodiment of the present invention.

Step S9 is to hide the image so that only the image description information is displayed on the image display window.

Fig. 6 is a schematic diagram of description information according to an embodiment of the present invention, where a pixel value of display data is temporarily set to 0, at this time, all of the DIOCM image display contents in the window are empty, the window completely displays a background, and the current window image is captured, that is, the information description image. The 8 positions of the descriptive information tile are shown in fig. 6.

And step S10, intercepting the partial image according to the size of the description information block.

In the step, the length and height occupied by the image window periphery and the four-corner description information image block are calculated, and the size of a rectangular bounding box of a character description block is obtained by taking a pixel as a unit, namely W x H. The width and the height of the character description information block are calculated and recorded, and the recorded value is used as the original zooming value.

And intercepting a local image at a corresponding position and a corresponding size on the information description image according to the width and the height of the recorded text description information block. Fig. 7 is a partial image corresponding to the description information block 2 in fig. 6 according to an embodiment of the present invention, and fig. 8 is a partial image corresponding to the description information block 7 in fig. 6 according to an embodiment of the present invention. Scaling the partial image according to the set description information scaling percentage,

and step S11, performing off-line rendering image combination, and replacing the window texture to be drawn of the virtual window with the zoomed partial image.

The window pattern to be drawn according to the OpenGL virtual window shown in fig. 6 is an image with a converted size. The color mapping information (recorded in the form of window width bed) recorded in step S3 is set in the display data, and the pixel value of the corresponding position point is assigned as the pixel value on the partial image in an alternative manner, so as to obtain fig. 9, where fig. 9 is a schematic diagram of an image generated after the partial image is fused with the image in fig. 6 in an embodiment of the present invention. In the pictures of fig. 2, 5, 6, 7, 8, and 9, a black border line is added to distinguish the picture boundaries, but the border line does not exist in the actual image.

And step S12, outputting and storing the finally generated image to be rendered of the virtual OpenGL window as a DICOM image, naming the generated image according to the DICOM image name input in the step S6, and storing the image to be rendered of the virtual OpenGL window under the DICOM storage path set in the step S6. .

Step S13, clear all the resources used and created by the virtual OpenGL window, and close the virtual OpenGL window.

Through the steps, the DICOM data in the browsing window can be output as an image with a specific size by using the original data on the basis of ensuring the data value as much as possible.

Further, the above method may also be applied to multimodal fusion data. When the window display data is multi-modal data, that is, the displayed data is two sets of data to be displayed in a fused manner, only the three-dimensional space information of the two sets of data needs to be stored in step S2, and the color mapping lookup table of the fused data needs to be stored, when the display data is set in step S8, the display data in the virtual window is set according to the sequence of loading the two sets of data by software, after the setting is completed, the color mapping lookup table is set to the second set of data, the rest steps do not need to be changed, and the steps are similar to the steps of the single-modal data method, and are not repeated here.

It should be noted that, in this embodiment, the output image is data to be rendered acquired in the virtual window, and therefore, the output image may also be output in different format types according to needs.

Based on the steps, the method and the mechanism for processing and outputting the DICOM image are established, firstly, a DIOCM image displayed in a current window is obtained: in the image browsing process, if the browsed DICOM image needs to be output and stored, window viewport information where the image to be output and stored is located is obtained, and the spatial position information where the currently displayed image is located is recorded, and is used for setting relevant attributes such as output image size, zooming, color mapping configuration information and the like when the output image is generated. Secondly, acquiring description information of the displayed DICOM image: and hiding the data information of the window to obtain an information image only with image information. And (3) cutting the information image, and cutting the information of each block along the maximum text surrounding frame to form one or more local images. The relative position information of all the partial information and the partial image information are associated and recorded for re-laying out the image description information when generating the output image. Finally, an output image is constructed: the projection relation is established according to the three-dimensional space projection principle in computer graphics, and the reconstruction method is based on multi-planar reconstruction (MPR). When the size of the output image needs to be Width pixels and Height pixels, all pixel values of Width multiplied by Height pixels in the DICOM image actually corresponding to the output image are calculated by utilizing position information, visual angle information, scaling relation and the like of the image, color mapping information is set for the pixel values, and the processed pixel set can form a two-dimensional image. The recorded local image information is zoomed according to the set zoom ratio, then the local image and the generated two-dimensional image are fused with corresponding pixel points according to the position of the local image relative to the original image, so that a new image can be generated, and the image with the corresponding format is generated according to the required output format and is stored in a specified path

In summary, with the method for processing DICOM data provided by the embodiment of the present disclosure, on one hand, when a DICOM image is browsed, the local image corresponding to the description information and the DICOM image are divided and then independently zoomed, and then fused with the original DICOM image, so that details of the original data can be retained, local deformation caused by forcibly zooming the image according to the size of the window is avoided, and the problem of influence on analysis and diagnosis of a doctor due to image deformation is solved; on the other hand, the two-dimensional image is combined with the adjusted image to be drawn and displayed in the virtual window, so that the description information can be zoomed according to the setting during display, the displayed information is reduced, the shielding of the image information is reduced, and the output image is optimized.
