Referring to fig. 1, a flowchart of a method for constructing an intravascular ultrasound image according to an exemplary embodiment is shown, as shown in fig. 1, including:
s101: acquiring line data in each frame of cross-section image of the intravascular ultrasound image, and processing the line data into line data to be displayed;
in the specific implementation, a small high-frequency ultrasonic probe is arranged on a catheter, the probe is placed in a blood vessel, the probe is pulled back at a constant speed under the control of a motor, and therefore a series of intravascular ultrasonic images are obtained, wherein the intravascular ultrasonic images contain original line data and need to be stored to construct longitudinal section images.
In this embodiment, before storing the line data, the original line data is preprocessed into line data to be displayed, and when a target longitudinal-section image is subsequently constructed, the processed line data to be displayed is directly used, so that the processing time of the original line data can be reduced.
As a possible implementation, the step of processing the original line data into line data to be displayed includes: and carrying out interpolation processing and resampling processing on the line data to obtain the line data to be displayed. In specific implementation, digital signal processing may be performed on each pixel point in the original line data, and the processed line data may be directly displayed, where the processing may include interpolation processing, resampling processing, and the like.
S102: storing the line data to be displayed and the corresponding longitudinal section identification according to a preset data structure according to the longitudinal section corresponding to the line data to be displayed;
it can be understood that each processed line data to be displayed corresponds to a longitudinal section, where the longitudinal section is specifically a section of a blood vessel, and a tangent line intersects with a central axis of the blood vessel, taking the number of lines 512 as an example, and contains 256 longitudinal section images in total.
In this step, a longitudinal section corresponding to the line data to be displayed is determined, and the line data to be displayed and the corresponding longitudinal section identifier are stored according to a preset storage mode, so as to be used for constructing an ultrasonic image of the target longitudinal section.
As a possible implementation manner, the storing the line data to be displayed and the corresponding longitudinal section identifier according to a preset storage manner includes: and storing the data of the lines to be displayed corresponding to the same longitudinal section mark into a group of longitudinal section image data, wherein the group number of the longitudinal section image data corresponds to the number of the longitudinal section marks. In the implementation, as shown in fig. 2, the intravascular ultrasound image includes a total of 256 longitudinal-sectional images, which are 1024 frames, 512 lines and 580 points per line, for example. And adding the data of the lines to be displayed to the corresponding longitudinal-section image to generate longitudinal-section image data, storing the data to be displayed according to the longitudinal-section image, and storing the data to be displayed corresponding to one longitudinal-section image to one page. In the present embodiment, 256 pages are included in total, and the data structure of the vertical slice image data is char A [256] [1024 × 580].
As another possible implementation manner, the storing the line data to be displayed and the corresponding longitudinal section identifier according to a preset storage manner includes: and storing the line data to be displayed, which is obtained by processing the line data in each frame of cross-section image, into a group of frame image data, wherein the group number of the frame image data corresponds to the frame number of the cross-section image.

And storing the data to be displayed according to the received data frame, and storing one frame of data to one page. In the present embodiment, 1024 pages are included, and the data structure of the frame data is char A [1024] [256 × 580].
It should be noted that, although not specifically limited herein, the line data to be displayed may be stored in any one of the above embodiments, or both of the above embodiments may be simultaneously selected to store the line data to be displayed.
It can be understood that, in the process of storing the line data to be displayed, the longitudinal section image in the blood vessel can be imaged in real time, the user can specify the longitudinal section image to be displayed, namely the target longitudinal section, and the program displays the target longitudinal section image based on the target line data to be displayed corresponding to the target longitudinal section. As a feasible implementation manner, a corresponding identifier may be set for each longitudinal plane, the user only needs to input the identifier of the target longitudinal plane to be displayed, and the program may read the corresponding target line data to be displayed according to the identifier of the target longitudinal plane, and display the target longitudinal plane image based on the target line data to be displayed. And if the user does not specify the target longitudinal section to be displayed, displaying the ultrasonic image of the default longitudinal section. The user can flexibly set the angle of the tangent line corresponding to the default longitudinal section in advance, and the angle is not specifically limited here. Certainly, in the real-time imaging process, in order to facilitate the medical staff to view the information, the original line data can be subjected to digital signal processing such as interpolation, resampling and the like to display the cross-section image in the blood vessel.
S103: and reading the target to-be-displayed line data corresponding to the target longitudinal section mark according to the received section display command, and displaying the data as a target longitudinal section image.
The purpose of this step is to display a longitudinal sectional image of the target. In the specific implementation, on the basis of storing the line data to be displayed and identifying the corresponding longitudinal section, when loading the target longitudinal section image, only the corresponding required target line data to be displayed needs to be read, taking the intravascular ultrasound image as 1024 frames, the number of line taking 512, and 580 points per line as an example, the data amount of the target line data to be displayed is 1024 × 580b =0.56mb, the reading time is less than 10 milliseconds calculated at the mechanical hard disk reading-writing speed of 150MB/s, and compared with a scheme of directly reading the original line data by the related technology, the data reading time is greatly reduced.
As a possible implementation, the displaying is a target longitudinal section image, and includes: adding pseudo colors to the target line data to be displayed, and displaying the data as a target longitudinal section image. In specific implementation, the user may also designate an identifier of a target longitudinal section to be displayed, and the program reads corresponding target line data to be displayed according to the identifier and adds pseudo colors to the target line data to be displayed to display a target longitudinal section image. It can be understood that, in the pseudo-color process of the line data to be displayed of the target, the user can adjust the pseudo-color mode in real time to adjust the definition of the displayed long-axis ultrasonic image, and the construction and display mode of the longitudinal section image in the blood vessel are more flexible.
It can be understood that, in order to facilitate the medical staff to view the information, when receiving the section display command, the digital signal processing such as interpolation, resampling and the like can be carried out on the original line data, so as to display the cross-section image in the blood vessel. That is, the present embodiment further includes: storing the original line data; and if a section display command is received, reading the original line data, and performing digital signal processing on the original line data to display the ultrasonic image of the cross section of the blood vessel.
According to the method for constructing the intravascular ultrasound image, before the line data is stored, the original line data is processed into the line data to be displayed, the longitudinal section corresponding to the line data to be displayed is determined, and the line data to be displayed and the corresponding longitudinal section identification are stored according to a preset storage mode. When the target longitudinal section image is constructed, only the target to-be-displayed line data corresponding to the target longitudinal section identifier needs to be read, and all original line data does not need to be read, so that the data reading amount is greatly reduced, and the construction time of the target longitudinal section image is shortened. Meanwhile, because the line data to be displayed is the processed line data, the processing time of the original line data is saved when the target longitudinal-section image is constructed, and the construction time of the target longitudinal-section image is further reduced. Therefore, the construction method of the intravascular ultrasound image improves construction efficiency of the intravascular longitudinal section image.
The embodiment of the application discloses a method for constructing an intravascular ultrasound image, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme. Specifically, the method comprises the following steps:
referring to fig. 4, a flowchart of another intravascular ultrasound image construction method according to an exemplary embodiment is shown, as shown in fig. 4, including:
s201: acquiring line data in each frame of cross-section image of the intravascular ultrasound image, and processing the line data into line data to be displayed;
s202: storing the data of the lines to be displayed corresponding to the same longitudinal section mark into a group of longitudinal section image data, wherein the group number of the longitudinal section image data corresponds to the number of the longitudinal section marks;
s203: performing pseudo color on the longitudinal section image data to generate pseudo color data, and storing the pseudo color data;
in this embodiment, the pseudo color is performed on the longitudinal-section image data after the longitudinal-section image data is generated to generate and store pseudo color data, and when a target longitudinal-section image is subsequently constructed, the target pseudo color data corresponding to the target longitudinal-section is directly used, so that the pseudo color time can be reduced, and the construction time of the target longitudinal-section image can be further reduced.
S204: and reading target pseudo-color data corresponding to the target longitudinal section identification according to the received section display command, and displaying the target longitudinal section image based on the target pseudo-color data.
In this step, target pseudo-color data corresponding to the target longitudinal section is read, and a long-axis ultrasonic image of the target longitudinal section is constructed and displayed based on the target pseudo-color data.
Therefore, in the embodiment, the corresponding pseudo-color data is generated and stored based on the longitudinal section image data, and when the target longitudinal section image is constructed, the target pseudo-color data corresponding to the target longitudinal section is directly used, so that the pseudo-color time in constructing the long-axis ultrasonic image can be reduced, the construction time of the target longitudinal section image is further reduced, and the construction efficiency of the longitudinal section image in the blood vessel is improved.
The embodiment of the application discloses a method for constructing an intravascular ultrasound image, and compared with the first embodiment, the embodiment further explains and optimizes the technical scheme. Specifically, the method comprises the following steps:
referring to fig. 5, a flowchart of another intravascular ultrasound image construction method according to an exemplary embodiment is shown, as shown in fig. 5, including:
s301: acquiring line data in each frame of cross-section image of the intravascular ultrasound image, and processing the line data into line data to be displayed;
s302: storing the line data to be displayed and the corresponding longitudinal section identification according to a preset data structure according to the longitudinal section corresponding to the line data to be displayed;
s303: reading default to-be-displayed line data corresponding to the default longitudinal section identification according to the received section display command, and displaying the default to-be-displayed line data as a default longitudinal section image;
in this embodiment, when constructing the intravascular longitudinal plane image, the ultrasound image of the default longitudinal plane is displayed first, and the user may flexibly set the angle of the tangent line corresponding to the default longitudinal plane, which is not specifically limited in this embodiment. In specific implementation, the default to-be-displayed line data corresponding to the default longitudinal section is read, and the default longitudinal section image is displayed based on the default to-be-displayed line data.
S304: calculating a tangent plane angle between the target longitudinal tangent plane and the default longitudinal tangent plane according to a target longitudinal tangent plane identifier contained in the received longitudinal tangent plane adjustment command;
s305: and reading target to-be-displayed line data corresponding to the target longitudinal section according to the section angle, and displaying the target longitudinal section image based on the target to-be-displayed line data.
In an implementation, the user may make a slice angle adjustment based on a default longitudinal slice to display a long-axis ultrasound image of the target longitudinal slice. As a possible implementation manner, a corresponding identifier may be set for each longitudinal plane, the user only needs to input the identifier of the target longitudinal plane to be displayed, the program may calculate a plane angle between the target longitudinal plane and the default longitudinal plane according to a difference between the identifier of the target longitudinal plane and the identifier of the default longitudinal plane, read the target line-to-be-displayed data corresponding to the target longitudinal plane based on the plane angle, and display the target longitudinal plane image based on the target line-to-be-displayed data. It can be understood that the processing time required for displaying the long-axis ultrasound image of a longitudinal section is mainly the loading time of the section, so that repeated operation is not required after reading the target longitudinal-section image data based on the section angle, and the section adjustment time is less than 10 milliseconds taking 1024 frames of the intravascular ultrasound image, 512 line-taking numbers and 580 points per line as examples.
As can be seen from the above discussion, in the present embodiment, when constructing the longitudinal-section image in the blood vessel, the ultrasound image of the default longitudinal section is displayed first, and the user may adjust the section angle based on the default longitudinal section to display the target longitudinal-section image. When the tangent plane is adjusted, the default longitudinal tangent plane is loaded, so that repeated loading operation of the target longitudinal tangent plane is not needed, and the tangent plane adjusting speed is increased. Therefore, the loading playback speed and the section adjusting speed of the historical longitudinal section image data are increased, medical staff can conveniently and quickly check the longitudinal section image information, and the medical staff can be supported to make a diagnosis decision quickly.
