Detailed Description

In the embodiment of the present invention, it is considered that when guiding with an image such as an X-ray image or a CT image, a user may be more interested in a certain partial region, that is, an attention region, in the image, but in the current image presentation technology, the whole image is considered as a whole, for example, a set of uniform image processing algorithms is used to perform processing such as noise reduction, edge sharpening, contrast enhancement and the like on all images. It cannot identify which areas are of interest to the user and therefore cannot guarantee the sharpness of the image of the areas of interest to the user. Therefore, in the embodiment of the invention, the attention area of the user is acquired, and the image processing is performed on the whole image by taking the attention area of the user as a standard. Further, the imaging can be performed by taking the attention area of the user as a standard, so that the presented image can not only ensure the image quality of the attention area, but also reduce the radiation dose as much as possible.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by referring to the following examples.

Fig. 1 is an exemplary flowchart of an image presenting method in interventional therapy in an embodiment of the present invention. As shown in fig. 1, the method may include the steps of:

step 101, acquiring a current image acquired by an X-ray device.

The current image is a current real-time image for guiding an interventional operation, may be an X-ray image acquired by a medical angiography X-ray machine, and may be an image obtained at an initial stage according to an initial scanning parameter or a default scanning parameter, for example, when a scanning parameter corresponding to an imaging requirement meeting a set guide wire material is taken as the default scanning parameter by default, the current image is an initial image, and may be an image obtained by using the default scanning parameter; or it may be an image based on previously determined scan parameters. Wherein the scanning parameters include exposure parameters.

Step 102, a region of interest in the current image is determined.

Typically, more than one target object may be included in an image, such as a guidewire, catheter, stent, etc., may be included in a single image. There is therefore a need to determine the region of interest in order to more accurately determine the target of interest to the user.

Specifically, the region of interest may be automatically selected by the system, for example, a fixed region, such as a region in the middle of the image, may be set in the image, and then the set region in the current image may be determined as the region of interest. In the embodiment of the present invention, the set region may be a default initial region, or may be set by a user before or during the examination or treatment. For example, the method may further comprise: providing a service interface of one-man-machine interaction of a user, receiving configuration information of a focus area input by the user through the service interface, and obtaining the set area according to the configuration information.

Alternatively, the user may manually select the region of interest in the current image and then acquire the region manually selected by the user, and considering that the region manually selected by the user may be irregular, a standardized size may be predetermined for facilitating subsequent image processing, and then the acquired region may be standardized according to the set standardized size to obtain the region of interest. In a specific implementation, more than one standardized size may be set, for example, three standardized sizes, i.e., a large standardized size, a medium standardized size, and a small standardized size, and the region of interest is obtained by performing the standardization process according to the closest standardized size according to the size of the region manually selected by the user.

Step 103, segmenting the image of the region of interest from the current image.

In this step, an image of the region of interest is extracted from the current image and is subjected to subsequent analysis processing.

Step 104, identifying a target which is interested by a user from the image of the attention area; the target of interest to the user is a predetermined intervention consumable, intervention equipment or human tissue target in intervention treatment, such as a catheter, a guide wire, a stent, a spring ring, iodized oil, a blood vessel and the like.

In this step, during specific implementation, there may be multiple implementation manners, for example, a template of each user interest target may be predetermined, such as a template of a guidewire type intervention consumable, a template of a catheter type intervention consumable, a template of a stent type intervention device, a template of a spring-ring type intervention device, a template of an iodine oil type intervention consumable, and the like, then the image of the interest region is matched with the predetermined template of each user interest target, and then the user interest target in the image of the interest region is obtained according to a matching result, for example, the user interest target corresponding to the template whose matching degree meets a set requirement is used as a candidate user interest target in the image of the interest region.

If the number of the obtained candidate user interest targets is 1, the candidate user interest targets are directly determined as the identified user interest targets, and if the number of the obtained candidate user interest targets is greater than 1, the candidate user interest target with the highest imaging requirement (for example, in X-ray imaging, the image signal-to-noise ratio is relatively worst) among the candidate user interest targets can be determined as the identified user interest target.

In addition, in consideration of the possibility of a failure in identifying the target of interest of the user, that is, the matching degree between the image of the region of interest and all the templates fails to meet the set requirement, in this embodiment, a default target material, such as a guide wire, may be preset, and in this step, if the identification of the target of interest of the user fails, the preset default target material may be used as the identified target of interest of the user. Or, in this embodiment, a default target material may not be set, and in this step, if the target identification interested by the user fails, a message indicating that the identification fails may be returned.

And 105, acquiring a personalized image processing algorithm aiming at the identified user interest target from the preset personalized image processing algorithms aiming at the user interest targets.

In this embodiment, it is considered that the image processing emphasis points of the objects of interest of different users may be different, for example, the guide wire may adopt a somewhat simpler personalized image processing algorithm, such as edge sharpening and contrast enhancement. The iodine oil may need to have a certain rendering effect because of the need to have a hierarchical sense. Therefore, in the embodiment, different image processing can be preset for various targets of interest of different users, and corresponding personalized image processing algorithms can be preset. Correspondingly, in the step, only the personalized image processing algorithm aiming at the identified user interest target needs to be obtained.

And 106, processing the current image by using the acquired personalized image processing algorithm and then displaying the processed image.

In the step, the current image is processed by adopting an image processing algorithm of the user interest target identified by aiming at the attention area, and then the processed image is presented. Therefore, the whole image can be subjected to image processing by taking the attention area of the user as a standard, and the presentation definition of the user interest target in the attention area of the user is ensured.

In addition, in consideration of the possibility of a failure in identifying the target of interest of the user, that is, the matching degree between the image of the region of interest and all the templates fails to meet the set requirement, in this embodiment, a default target material, such as a guide wire, may be preset, and in this step, if the identification of the target of interest of the user fails, the preset default target material may be used as the identified target of interest of the user. Alternatively, in this embodiment, a default target material may not be set, and in step 104, if the target of interest of the user fails to be identified, a message indicating that the identification fails may be returned. Accordingly, in this embodiment, a general image processing algorithm may be preset, and when a message indicating that the identification fails is returned in step 104, the current image is processed by using the general image processing algorithm and then displayed. The general image processing algorithm may include some simple processes such as noise reduction, edge sharpening, and contrast enhancement.

In this embodiment, after step 104, the method may further include: determining a developing material of the user interest target according to a pre-stored corresponding relation between the user interest target and the developing material, determining a current exposure parameter according to the developing material, and controlling the X-ray equipment to acquire an image by using the exposure parameter.

For example, the catheter-like material is typically polyester fiber, the guidewire-like material is typically iron, and the stent-like material is typically titanium alloy, nickel titanium alloy, or the like. In this embodiment, a material database of each user-interested target may be preset, and a set of exposure parameters may be stored corresponding to the requirement of the developing material of each user-interested target for the signal-to-noise ratio. In this way, the imaging can be performed with the region of interest of the user as a standard, so that the presented image can both guarantee the image quality of the region of interest and reduce the radiation dose as much as possible.

Further, it is considered that the object of interest of the user may have failed to be identified in step 104, and a message indicating the failure of the identification is returned. Accordingly, in this embodiment, a set of default exposure parameters may be preset, and when a message indicating that the identification fails is returned in this step 104, the default exposure parameters may be determined as the current exposure parameters, and imaging may be performed using the exposure parameters.

In addition, the embodiment of the invention allows the user to correct the materials of the target of interest of the user, which is determined by the system. Accordingly, the method may further comprise: and providing a service interface for further human-computer interaction of the user, receiving the change of the developing material of the target which is interested by the user and input by the user through the service interface, and returning to execute the operation of determining the current exposure parameter according to the developing material.

In addition, the embodiment of the invention also allows the user to change the attention area in the checking process. Accordingly, the method further comprises: receiving the change of the attention area by the user, standardizing the changed attention area according to the set standardized size to obtain an updated attention area, and returning to execute the step 103.

In addition, the personalized image processing in the embodiment of the invention is image processing for presenting images in real time, and the corresponding personalized image processing algorithm takes the principle of not influencing the display real-time performance of the images as a principle.

The image presenting method in the interventional therapy in the embodiment of the present invention is described in detail above, and the image presenting system in the interventional therapy in the embodiment of the present invention is described in detail below.

It should be noted that not all steps and modules in the above flows and structures are necessary, and some steps or modules may be omitted according to actual needs. The execution order of the steps is not fixed and can be adjusted as required. The division of each module is only for convenience of describing adopted functional division, and in actual implementation, one module may be divided into multiple modules, and the functions of multiple modules may also be implemented by the same module, and these modules may be located in the same device or in different devices.

It is understood that the hardware modules in the above embodiments may be implemented mechanically or electronically. For example, a hardware module may include a specially designed permanent circuit or logic device (e.g., a special purpose processor such as an FPGA or ASIC) for performing specific operations. A hardware module may also include programmable logic devices or circuits (e.g., including a general-purpose processor or other programmable processor) that are temporarily configured by software to perform certain operations. The implementation of the hardware module in a mechanical manner, or in a dedicated permanent circuit, or in a temporarily configured circuit (e.g., configured by software), may be determined based on cost and time considerations.
