Description

Technical Field

[0001] The present invention relates to the medical field, and in particular to an image presentation method and system in medical imaging, an imaging system, and a computer-readable storage medium. Background Art

[0002] An aneurysm is a pathological protrusion of an arterial wall. For example, an intracranial aneurysm refers to an abnormal dilation of a cerebral artery. The incidence of intracranial aneurysms is approximately 5% to 10%, and they carry a high mortality and disability rate among young and middle-aged patients. Therefore, once diagnosed, necessary treatment is essential. With advances in technology, materials, and the accumulated experience of neurointerventional physicians, endovascular therapy has become the preferred treatment for intracranial aneurysms.

[0003] Endovascular aneurysm treatment involves inserting a microcatheter into the aneurysm and occluding it with materials such as coils and medical glue, thereby preventing bleeding and recurrence and allowing for recovery. In some treatments, such as for wide-necked or fusiform aneurysms, a stent combined with coiling is used for aneurysm embolization. A stent is a cylindrical stent that is delivered into the blood vessel using a specialized delivery system and adheres to the vessel wall. Pre-positioning the stent helps tightly pack the aneurysm and prevents the coils from protruding into the parent artery. Stent-coiling techniques can be performed in two ways. The first involves placing a stent across the aneurysm ostium. A microcatheter is then inserted through the stent mesh into the aneurysm cavity, where coils are inserted to occlude the aneurysm. The microcatheter is then removed. The second method involves inserting a microcatheter into the aneurysm cavity, placing a stent across the ostium, and then inserting coils through the microcatheter to embolize the aneurysm. Finally, the microcatheter is removed. During these procedures, the pre-placed stent may not be fully deployed, requiring further stent deployment after aneurysm embolization is complete.

[0004] During the process of intravascular treatment, radiological images are required for guidance. Since the contrast between blood vessels and surrounding tissues is low, the real-time images collected cannot be used directly for embolization guidance. Therefore, a vascular path map for navigation needs to be prepared separately. For example, Digital Subtraction Angiography (DSA) technology is usually used to subtract images containing contrast agents from images without contrast agents to obtain a vascular subtraction image. The vascular subtraction image is then reversed to obtain a vascular path map, which is then superimposed on the real-time image for embolization guidance. However, the above-mentioned vascular subtraction image will reduce or even remove the image of the stent in the blood vessel during the subtraction process. Therefore, the image of the stent will be weakened or even eliminated in the reversed vascular path map. Figure 1A The area in the box A should be the area where the stent is located, but the image of the stent is almost invisible, which is not conducive to the treatment of aneurysm embolization using stent combined with coil technology. Figure 1BAs shown, coil 11 is placed under the guidance of a vascular path map, while the stent's status is observed on another reference monitor. For applications requiring stent deployment after aneurysm embolization, another vascular path map is required to guide stent deployment. This process is not only time-consuming but also wastes contrast agent and increases X-ray dose. Summary of the Invention

[0030] In an embodiment of the present invention, to improve the efficiency of endovascular aneurysm treatment, a vascular navigation map and a stent map are displayed simultaneously in a single image. Instead of directly using the vascular path map obtained by highlighting the vascular subtraction image as the vascular navigation map, a vascular contour map is used. When superimposed on the real-time image, the vascular contour does not obscure the stent map. Similar approaches can also be used for other radiological image-based treatments, such as polyp treatment in the digestive tract.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail with reference to the following examples.

[0032] Figure 2 FIG. 1 is an exemplary flow chart of an image presentation method in medical imaging according to an embodiment of the present invention. Figure 2 As shown, the method may include the following steps:

[0033] Step 201 : Acquire an image containing no contrast agent and an image containing contrast agent of a target region including a first target.

[0034] In one example, the first target may be an aneurysm. For example, for a target region containing the aneurysm, an image of the target region without contrast agent and an image of the target region with contrast agent are acquired. The contrast agent is injected into a blood vessel. Accordingly, the X-ray device used to acquire the images may be a medical angiography X-ray machine.

[0035] In another example, the first target may be an intestinal polyp, in which case the contrast agent is injected into the intestine.

[0036] Step 202: Subtract the image containing the contrast agent from the image not containing the contrast agent to obtain a subtraction image.

[0037] In specific implementation, the image subtraction operation can be performed using a variety of methods. For example, a digital image difference algorithm can be used to perform a difference calculation on the image containing the contrast agent and the image not containing the contrast agent to obtain the subtraction image.

[0038] In one example, the subtraction image may be a blood vessel subtraction image; in another example, the subtraction image may be a bowel subtraction image.

[0039] Step 203: extract the second target contour from the subtraction image to obtain a second target contour image.

[0040] In specific implementation, there are various methods for extracting the second target contour. For example, edge detection algorithms and image segmentation algorithms can be used to detect and segment the second target contour from the blood vessel subtraction image.

[0041] In one example, the second target may be a blood vessel; in another example, the second target may be an intestine.

[0042] Step 204: register the second target outline image with the currently acquired real-time image based on the same marker and then overlay and display them.

[0043] The marker may be an object that is relatively static in the image and can be visualized in both ordinary X-ray images and enhanced images, such as bones.

[0044] In specific implementation, there can be multiple registration methods. For example, based on an image containing a contrast agent, two reference points (such as branch nodes) on the second target contour and a marker point on the marker can be determined, and the positional relationship between the two reference points and the marker point can be calculated. Then, the corresponding marker point on the same marker is determined in each real-time image collected, and based on the positional relationship, the second target contour map is registered with the real-time image, and then the pixel translation algorithm can be used to register and overlay the two in real time. Alternatively, the corresponding marker point on the same marker can be determined in a currently collected image, and based on the positional relationship, the second target contour map is registered with the image, and based on the registration relationship, the second target contour map is superimposed on the image and each real-time image collected thereafter. In other words, the registration process can be real-time registration or a one-time registration.

[0045] In this way, for endovascular treatment of aneurysms, there is no need to display the vascular path map and stent map separately on two screens. The vascular contour map and stent map used for guidance can be displayed simultaneously on one image, thereby improving the efficiency of endovascular treatment of aneurysms. In addition, for applications where the stent needs to be released after the aneurysm embolization is completed, since the stent map is always displayed in the real-time image, there is no need to create another vascular path map for guiding the stent release, thereby reducing the use of contrast agents and X-ray doses. For other treatments based on radiological images, such as intestinal resection of polyps, although stents are not necessarily required, the intestinal contour map can still be used as a navigation map.

[0046] Of course, in this embodiment, the positions of the system and the patient need to remain unchanged.

[0047] In this embodiment, the superimposed real-time image may be displayed on a real-time screen, and the real-time screen may refer to a screen / display for displaying the real-time image or a portion of the screen / display.

[0048] In addition, the present embodiment may allow the user to adjust the position of the second target outline image that needs to be superimposed and displayed on the real-time image. For example, if the user feels that the initial superimposed position automatically superimposed by the system in step 204 is not very accurate, the user may be allowed to perform position movement operations such as up, down, left, and right translation on the second target outline image. Accordingly, the present embodiment may further include: providing the user with a position adjustment function for the second target outline image superimposed and displayed on the real-time image, receiving the user's shift instruction for the second target outline image superimposed and displayed on the real-time image, and adjusting the position of the second target outline image according to the shift instruction. In addition, if the user is not satisfied with the position that he or she manually adjusted, the present embodiment may further provide the user with a function to restore the initial superimposed position. Accordingly, the user may receive a reset instruction for the second target outline image superimposed and displayed on the real-time image, and according to the reset instruction, restore the second target outline image to the initial superimposed position.

The following describes in detail the image presentation system for interventional treatment in an embodiment of the present invention.

[0055] In a specific implementation, the third unit 303 may use an edge detection algorithm and an image segmentation algorithm to detect and segment the second target contour from the subtraction image.

[0056] The fourth unit 304 is configured to register the second target outline image with the currently acquired real-time image based on the same marker and then overlay and display the two images.

[0057] In specific implementation, the fourth unit 304 can further determine two reference points on the second target contour and a marker point on the marker based on the image containing the contrast agent, and calculate the positional relationship between the two reference points and the marker point; then determine the corresponding marker point on the same marker in each currently acquired real-time image, and based on the positional relationship, align the second target contour map with the real-time image, and use a pixel translation algorithm to superimpose and display the two; or, determine the corresponding marker point on the same marker in a currently acquired image, and based on the positional relationship, align the second target contour map with the image, and superimpose the second target contour map on the image and each real-time image acquired thereafter based on the alignment relationship.

[0064] An embodiment of the present invention further provides an imaging system, which includes an X-ray device such as a medical angiography X-ray machine and an image presentation system for medical imaging in any of the above embodiments.

[0065] It should be noted that not all steps and modules in the above processes and structure diagrams are required, and some steps or modules can be omitted based on actual needs. The division of modules is merely for the purpose of describing the functional division adopted. In actual implementation, a module can be implemented by multiple modules, and the functions of multiple modules can be implemented by the same module. These modules can be located in the same device or in different devices.

[0066] It will be appreciated that the hardware modules described in the above embodiments can be implemented mechanically or electronically. For example, a hardware module may include a specially designed permanent circuit or logic device (e.g., a dedicated processor, such as an FPGA or ASIC) to perform a specific operation. A hardware module may also include a programmable logic device or circuit (e.g., a general-purpose processor or other programmable processor) temporarily configured by software to perform a specific operation. Whether to implement a hardware module mechanically, using a dedicated permanent circuit, or using a temporarily configured circuit (e.g., configured by software) can be determined based on cost and time considerations.

Furthermore, instructions based on the program code can be used to cause an operating system, etc., operating on the computer to perform some or all of the actual operations. The program code read from the storage medium can also be written to a memory provided in an expansion board inserted into the computer or to a memory provided in an expansion unit connected to the computer. Subsequently, based on the instructions of the program code, a CPU, etc., installed in the expansion board or expansion unit can be configured to perform some or all of the actual operations, thereby implementing the functions of any of the aforementioned embodiments. Examples of storage media for providing the program code include floppy disks, hard disks, magneto-optical disks, optical disks (such as CD-ROMs, CD-Rs, CD-RWs, DVD-ROMs, DVD-RAMs, DVD-RWs, and DVD+RWs), magnetic tapes, non-volatile memory cards, and ROMs. Alternatively, the program code may be downloaded from a server computer via a communications network.

[0068] It can be seen from the above scheme that since in the embodiment of the present invention, the second target contour map such as the blood vessel contour map superimposed on the real-time image will not block other object images such as the stent image on the real-time image, the second target contour map such as the blood vessel contour map and other object images such as the stent image used for guidance can be displayed simultaneously on one image, without the need to display the second target contour map such as the blood vessel path map and other object images such as the stent image separately on two display screens, thereby improving the efficiency of radiological image-based treatments such as intravascular treatment of aneurysms.

[0069] In addition, for applications where the stent needs to be released after aneurysm embolization is completed, since the stent image is always displayed in the real-time image, there is no need to create another vascular path map to guide the stent release, reducing the use of contrast agents and X-ray doses.

[0070] In addition, real-time registration of superimposed images can make the display more accurate, while one-time registration of superimposed images can reduce the amount of calculation.

[0071] In addition, by providing the function of manually adjusting or resetting the superposition position, the superposition effect can be adjusted according to actual conditions, thereby enhancing the applicability of the system.
