Description

Technical Field

[0001] The embodiments of the present invention relate to the field of angiography technology, and in particular to an image display method, an image display device, an angiography device and a storage medium. Background Art

[0002] Angiography is an auxiliary examination technology that uses the principle that X-rays cannot penetrate contrast agents to observe vascular lesions. It is widely used in the diagnosis and treatment of various diseases in clinic. At the same time, angiography is a minimally invasive technology that requires inserting a catheter into the blood vessel to inject contrast agents into the blood vessel, and then using imaging equipment to image the blood vessel.

[0003] When viewing the imaging results, doctors need to continuously zoom in or out the image in order to obtain comprehensive vascular information, thereby continuously switching between images of different fields of view on the display screen.

[0004] Based on the above existing technical solutions, when doctors perform angiography, if they need to compare images of different fields of view, they need to switch images continuously. Since users need to switch the vascular images on the display device continuously, the imaging object needs to be rescanned each time the switch is made, which reduces the diagnostic efficiency of angiography. At the same time, repeated switching also increases the risk of error in the diagnostic results of angiography. Summary of the invention

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0025] Embodiment 1

[0026] Figure 1 This is a flow chart of an image display method provided in the first embodiment of the present invention. This embodiment is applicable to the case where angiography equipment is used for imaging and the imaging results are displayed. The method can be executed by an image display device, which can be implemented in software and / or hardware, and can be configured in angiography equipment. Specifically, the following steps are included:

[0027] S110 , acquiring a first blood vessel image of the imaging object acquired by a blood vessel angiography device based on a first field of view parameter, and displaying the first blood vessel image.

[0028] Angiography is a technology that visualizes blood vessels in X-ray sequence images. Contrast agents are injected into blood vessels. Since X-rays cannot penetrate contrast agents, angiography uses X-rays to scan and image the measured area. The contrast agent creates a material density difference between the blood vessels and other tissues in the measured area, so that the scanned image can accurately reflect the location and extent of vascular lesions.

[0029] Wherein, exemplary, the first field of view parameter includes but is not limited to at least one of a first field of view range, a first magnification, a first field of view center position and a first imaging mode. Taking the abdomen as an example of the imaging object, specifically, the first field of view range can be used to describe the size of the region corresponding to the imaging object in the first blood vessel image. Exemplarily, assuming that the overall region size corresponding to the abdomen is 100*100, the first field of view range can be 100*100, or 30*50. When the first field of view range is 30*50, the first field of view range includes a part of the field of view range in the abdomen field of view range. Specifically, the first magnification ratio can be used to describe the magnification ratio of the first blood vessel image to the imaging object, similar to magnifying the blood vessel 100 times in the image. Wherein, the first magnification ratio can be a relative magnification ratio relative to the standard magnification ratio, or it can be an actual magnification ratio relative to the image of the blood vessel. If the first magnification ratio is a relative magnification ratio relative to the standard magnification ratio, when the first magnification ratio is greater than the standard magnification ratio, the first blood vessel image is an enlarged image relative to the image corresponding to the standard magnification ratio, and when the first magnification ratio is less than the standard magnification ratio, the first blood vessel image is a reduced image relative to the image corresponding to the standard magnification ratio.

[0030] Specifically, the center position of the first field of view can be used to describe the image center position of the first blood vessel image. From the perspective of the angiography device, the center position of the first field of view can be used to describe the position on the detector corresponding to the center position of the beam of the ray source. Specifically, the first imaging mode includes a perspective mode or an exposure mode. Among them, the perspective mode is an imaging mode with a large radiation dose and a low image resolution, and the exposure mode is an imaging mode with a small radiation dose and a high image resolution. Specifically, in actual application scenarios, users can switch imaging modes by using the Zoom function on the angiography device.

[0031] In one embodiment, displaying the first blood vessel image includes: displaying the first blood vessel image in a preset display area of ​​a display device, or displaying the first blood vessel image on an entire display interface of the display device.

[0032] S120: Determine a second field of view parameter based on the received parameter adjustment instruction and the first field of view parameter.

[0033] In this embodiment, the parameter adjustment instruction includes a zoom adjustment ratio. Specifically, when the zoom adjustment ratio is greater than one, the second magnification in the second field of view parameter is greater than the first magnification or the second field of view range is smaller than the first field of view range. When the zoom adjustment ratio is less than one, the second magnification in the second field of view parameter is less than the first magnification or the second field of view range is larger than the first field of view range. From the perspective of the vascular image, when the zoom adjustment ratio is greater than one, a zoom-in operation is performed on the first vascular image. When the zoom adjustment ratio is less than one, a zoom-out operation is performed on the first vascular image.

[0034] When the parameter adjustment instruction only includes the scaling adjustment ratio, if the scaling adjustment ratio is 1, the first field of view parameter is the second field of view parameter at this time, and the second vascular image obtained subsequently is exactly the same as the first vascular image. In one embodiment, optionally, after determining the second field of view parameter based on the received parameter adjustment instruction and the first field of view parameter, it also includes: if the first field of view parameter is the same as the second field of view parameter, a prompt message is generated. Specifically, the prompt message can be used to prompt the user that the vascular image corresponding to the parameter adjustment instruction already exists. Further, the user can also be prompted to the display position of the vascular image corresponding to the current field of view adjustment parameter. Exemplarily, the prompt method can be at least one of a text prompt, a voice prompt and a prompt light. A corresponding prompt light can be set for at least one display device, and if the vascular image currently displayed on the display device corresponds to the current parameter adjustment instruction, the prompt light flashes. The advantage of such a setting is to avoid displaying vascular images with the same field of view parameters, resulting in a waste of display positions and reducing the utilization rate of the display device.

[0035] In one embodiment, optionally, determining the second field of view parameter based on the received parameter adjustment instruction and the first field of view parameter includes: determining the second magnification in the second field of view parameter based on the zoom adjustment ratio and the first magnification in the first field of view parameter. Exemplarily, assuming that the first magnification in the first field of view parameter is 2 times relative to a preset standard magnification, and the zoom adjustment ratio is 3 times, the second magnification is 6 times.

[0036] In one embodiment, optionally, determining the second field of view parameter based on the received parameter adjustment instruction and the first field of view parameter includes: determining the second field of view range in the second field of view parameter based on the zoom adjustment ratio and the first field of view range in the first field of view parameter. Wherein, illustratively assuming that the first field of view range is 10*10 and the zoom adjustment ratio is 2 times, the second field of view range is 5*5.

[0037] On the basis of the above embodiment, when the parameter adjustment instruction only includes the zoom adjustment ratio, the second magnification ratio and the second field of view range are calculated based on the first magnification ratio, the first field of view range and the zoom adjustment ratio in the first field of view parameter. Exemplarily, the second field of view center position can be defaulted to the first field of view center position in the first field of view parameter, and the second imaging mode is defaulted to the first imaging mode in the first field of view parameter.

[0038] On the basis of the above embodiment, optionally, the parameter adjustment instruction also includes at least one of a field of view adjustment range, a field of view adjustment center position, and an imaging adjustment mode. Specifically, the user can customize the second field of view range, the second field of view center position, and the second imaging mode in the second field of view parameter. Specifically, the field of view adjustment range, the field of view adjustment center position, and the imaging adjustment mode in the parameter adjustment instruction are used as the second field of view range, the second field of view center position, and the second imaging mode, respectively. The parameter adjustment instruction can be generated based on the parameter value input by the user, or by obtaining the selection operation input by the user based on the displayed first vascular image. Exemplarily, the user can input the zoom adjustment ratio by using the Zoom function on the angiography device. The user can also input an image selection box based on the first vascular image, and generate the field of view adjustment range according to the size of the input image selection box.

[0039] S130 , determining a second blood vessel image based on the second visual field parameter, and synchronously displaying the second blood vessel image and the first blood vessel image.

[0040] In one embodiment, optionally, determining the second blood vessel image based on the second field of view parameter includes: acquiring the second blood vessel image acquired by an angiography device based on the second field of view parameter. Specifically, controlling the angiography device to acquire the second blood vessel image based on the second field of view parameter.

[0041] It should be noted that the embodiment of the present invention is explained by exemplifying the synchronous display of two vascular images. In practical applications, the image display method provided by the embodiment of the present invention can obtain more vascular images corresponding to different field of view parameters, and synchronously display each vascular image. The number of synchronously displayed vascular images is not limited here.

[0042] The technical solution of this embodiment solves the problem of repeatedly switching and displaying scanned images of different fields of view by determining the second blood vessel image based on the received parameter adjustment instruction while displaying the first blood vessel image, and synchronously displaying the second blood vessel image with the first blood vessel image, thereby reducing the number of repeated imaging and the amount of radiation, and increasing the service life of the angiography equipment, thereby also improving the diagnostic efficiency of angiography and reducing the error of the diagnostic result of angiography caused by repeated switching.

[0043] Embodiment 2

[0044] Figure 2is a flow chart of an image display method provided in Embodiment 2 of the present invention. This embodiment is a further refinement based on the above embodiment. Optionally, the second vascular image is synchronously displayed with the first vascular image, including: when a first visual field parameter corresponding to the first vascular image changes, acquiring an updated first vascular image acquired by an angiography device based on the changed first visual field parameter; determining an updated second visual field parameter based on the changed first visual field parameter and the parameter adjustment instruction, and synchronously displaying the updated second vascular image determined based on the updated second visual field parameter with the updated first vascular image.

[0045] The specific implementation steps of this embodiment include:

[0046] S210 , acquiring a first blood vessel image of an imaging object acquired by a blood vessel angiography device based on a first field of view parameter, and displaying the first blood vessel image.

[0047] S220 , determining a second field of view parameter based on the received parameter adjustment instruction and the first field of view parameter, and determining a second blood vessel image based on the second field of view parameter.

[0048] In one embodiment, optionally, the imaging object includes a blood vessel and a catheter inserted into the blood vessel, and the second field of view parameter is determined based on the received parameter adjustment instruction and the first field of view parameter, further comprising: when the zoom adjustment ratio is greater than one, obtaining a catheter tip image corresponding to the catheter in the first blood vessel image, and using the field of view center position and field of view range corresponding to the catheter tip image as the second field of view center position and second field of view range in the second field of view parameter, respectively.

[0049] Angiography is a technique for injecting contrast agents into target blood vessels by means of catheter intervention. Specifically, in angiography, a catheter is inserted into a blood vessel, and after the contrast agent is injected into the catheter, the contrast agent is transported to a designated blood vessel position through the catheter. During the catheter intervention process, the blood vessel needs to be imaged in real time in order to observe the position of the catheter in the blood vessel. In this embodiment, the first blood vessel image includes a catheter image. Specifically, the catheter image includes a catheter tip image, that is, an image obtained after imaging the tip of the catheter.

[0050] Wherein, the catheter tip image corresponding to the catheter in the first blood vessel image is obtained. Specifically, based on the preset division rule, the first blood vessel image is divided to obtain the catheter tip image. Exemplarily, the preset division rule includes a preset image size and a preset image shape. For example, the preset image shape can be a square, a rectangle, a circle or an irregular shape. Wherein, the preset image size can be determined according to the preset image shape. Exemplarily, when the preset image shape is a square, the preset image size can be 10mm*10mm, and when the preset image shape is a circle, the preset image size can be a radius of 5mm. Of course, the preset image size can also refer to the image area of ​​the catheter tip image.

[0051] The advantage of such a setting is that, by automatically identifying the catheter tip image in the first blood vessel image, the step of manually selecting the image of the region of interest is avoided. When the first blood vessel image changes, the catheter tip image in the changed first blood vessel image can also be tracked and identified in real time, thereby greatly improving the diagnostic efficiency of angiography in the subsequent angiography process.

[0052] Based on the above embodiment, optionally, determining the second vascular image based on the second field of view parameters includes: acquiring the second vascular image acquired by the angiography device based on the second field of view parameters; or, when the zoom adjustment ratio is greater than one, determining the reference vascular image in the first vascular image based on the second field of view center position and the second field of view range in the second field of view parameters, and determining the second vascular image based on the second magnification in the second field of view parameters and the reference vascular image.

[0053] Wherein, no matter whether the zoom adjustment ratio is greater than one or less than one, the angiography device can be controlled to acquire the second vascular image based on the second field of view parameters. In particular, when the zoom adjustment ratio is less than one, it means that a zoom-out operation is performed on the first vascular image. At this time, the second field of view is usually larger than the first field of view, that is, the first vascular image does not contain all the image information required for the second vascular image. At this time, it is necessary to re-control the angiography device to acquire the second vascular image based on the second field of view parameters. In another embodiment, when the zoom adjustment ratio is greater than one, it means that a zoom-in operation is performed on the first vascular image. At this time, the first vascular image usually contains all the image information required for the second vascular image. Of course, there may also be a situation where the first vascular image usually does not contain all the image information required for the second vascular image, such as when the center position of the second field of view is the boundary point of the first vascular image and the second field of view is not 0, in this case, the method of controlling the angiography device to acquire the second vascular image based on the second field of view parameters can also be used. In this embodiment, the first blood vessel image includes all the image information required by the second blood vessel image. The reference blood vessel image includes all the image information required by the second blood vessel image, and the magnification corresponding to the reference blood vessel image is the first magnification. Therefore, it is necessary to perform a magnification operation on the reference blood vessel image based on the second magnification in the second field of view parameter to obtain a second display image. Exemplarily, the algorithm in the process of performing the magnification operation includes but is not limited to at least one of a nearest neighbor interpolation algorithm, a bilinear interpolation algorithm, and a high-order interpolation algorithm.

[0054] The advantage of this arrangement is that by directly intercepting a reference vascular image from the first vascular image and directly obtaining a second vascular image based on the reference vascular image and the second field of view parameters, the number of repeated imaging and the amount of radiation are further reduced, thereby increasing the service life of the angiography device.

[0055] S230: synchronously display the second blood vessel image and the first blood vessel image.

[0056] In one embodiment, optionally, synchronously displaying the second blood vessel image with the first blood vessel image includes: displaying the second blood vessel image with the first blood vessel image simultaneously. This arrangement has the advantage of preventing the user from repeatedly switching between the first blood vessel image and the second blood vessel image.

[0057] S240: When a first visual field parameter corresponding to the first blood vessel image changes, acquiring an updated first blood vessel image acquired by the angiography device based on the changed first visual field parameter.

[0058] S250: Determine to update the second field of view parameter based on the changed first field of view parameter and the parameter adjustment instruction.

[0059] Wherein, when the parameter adjustment instruction remains unchanged, when the first field of view parameter changes, the first blood vessel image also changes, and at the same time, the second field of view parameter changes along with the first field of view parameter, thereby updating the second field of view parameter.

[0060] S260 , synchronously displaying the updated second blood vessel image determined based on the updated second visual field parameter and the updated first blood vessel image.

[0061] On the basis of the above embodiment, optionally, the second vascular image is synchronously displayed with the first vascular image, including: on the display device corresponding to the first vascular image, the second vascular image is displayed in a display area different from the first vascular image; or, the second vascular image is displayed on a display device different from the first vascular image. Specifically, in one embodiment, the display interface of the same display device includes at least two image display areas, one of which is used to display the first display image, and the other is used to display the second display image. In another embodiment, the angiography device includes at least two display devices, one of which is used to display the first display image, and the other is used to display the second display image.

[0062] Of course, when both the first visual field parameter and the second visual field parameter change, the updated first blood vessel image and the updated second blood vessel image obtained may also be displayed in different display areas of the display device, or may also be displayed on different display devices.

[0063] The technical solution of this embodiment determines the updated second field of view parameters based on the changed first field of view parameters and the parameter adjustment instruction, and synchronously displays the updated second vascular image determined based on the updated second field of view parameters and the updated first vascular image, thereby solving the problem of the user having to re-determine the second vascular image when the first vascular image changes, thereby improving the diagnostic efficiency of angiography and also avoiding positioning errors caused by human factors during repeated confirmation.

[0064] Embodiment 3

[0065] Figure 3 is a schematic diagram of an image display device provided in Embodiment 3 of the present invention. This embodiment can be applied to the case where angiography equipment is used for imaging and the imaging results are displayed. The device can be implemented in software and / or hardware, and the device can be configured in the angiography equipment. The image display device includes: a first blood vessel image display module 310, a second visual field parameter determination module 320, and a second blood vessel image display module 330.

[0066] The first blood vessel image display module 310 is used to obtain a first blood vessel image of the imaging object acquired by the angiography device based on the first field of view parameter, and display the first blood vessel image;

[0084] Embodiment 4

[0085] Figure 4 It is a structural schematic diagram of a vascular angiography device provided by the fourth embodiment of the present invention. The fourth embodiment of the present invention provides services for the implementation of the image display method described in any of the above embodiments of the present invention, and can be configured with the image display device in the third embodiment of the present invention.

[0086] The angiography device includes an imaging component 40, at least one display device 41 and a controller 42, wherein the imaging component 40 is used to acquire a first blood vessel image based on a first field of view parameter; the display device 41 is used to display the first blood vessel image and the second blood vessel image; the controller 42 includes one or more processors and a memory storing one or more programs, and when the one or more programs are executed by one or more processors, the one or more processors implement the image display method as described in any of the above embodiments.

[0087] In one embodiment, optionally, the imaging assembly 40 includes an X-ray source and a detector, wherein the X-ray source is used to emit X-rays, and the detector is used to generate a first blood vessel image according to the received X-rays.

[0088] In one embodiment, optionally, the X-ray source includes an X-ray high voltage generator and an X-ray tube. Among them, the types of X-ray high voltage generators include industrial frequency high voltage generators and high frequency inverter high voltage generators. The most commonly used one is the high frequency inverter high voltage generator, which is further divided into a continuous high frequency inverter high voltage generator and a computer-controlled pulsed high frequency inverter high voltage generator. Among them, the pulse wave of the continuous high frequency inverter high voltage generator during pulse acquisition needs to be generated by the grid switch control in the X-ray tube. Among them, the X-ray tube can receive high frequency and high voltage output to stimulate the generation of X-rays. The specification parameters of the X-ray tube include structural parameters and electrical parameters. The former refers to various parameters determined by the structure of the X-ray tube, such as the inclination angle of the target surface, the effective focus, the external dimensions, the weight, the filtration equivalent of the tube wall, the anode speed, the operating temperature and the cooling form. The electrical parameters refer to the specification data of the electrical performance of the X-ray tube, such as the filament heating voltage and current, the maximum tube voltage, the tube current, the maximum exposure time, the maximum allowable power and the anode heat capacity. The characteristics of X-ray tubes are small focus, high heat capacity, high load, high speed, and high heat dissipation rate. For example, liquid metal bearing technology can be used to make X-ray tubes, which can avoid the wear of bearings of ordinary tubes at high speeds, not only increase the heat dissipation efficiency, but also improve the ability of X-ray tubes to withstand continuous loads, increase the life of the tube, and reduce the intrinsic noise of the equipment, and improve the signal-to-noise ratio of the image.

[0089] In one embodiment, optionally, the detector comprises a flat panel detector.

[0090] Specifically, when the angiography device includes at least two display devices 41, the placement relationship between the display devices and the placement position of each display device can be selected according to the user's usage habits. When displaying vascular images with different magnifications on at least two display devices 41, the magnification levels of the vascular images corresponding to the different display devices 41 can be pre-set. For example, the magnification levels corresponding to the display devices A, B, and C are sequentially reduced, that is, the vascular image with the largest magnification is displayed on the display device A, and the vascular image with the smallest magnification is displayed on the display device C. The advantage of such a setting is that if the corresponding relationship between the vascular image and the display device is not set, when there are many display devices, the user needs to view the vascular image on each display device one by one to find the desired target vascular image when he wants to view the target vascular image, thereby increasing the burden of the user to find the target vascular image. By setting the corresponding relationship between the vascular image and the display device, the user can follow the corresponding relationship to search for the target vascular image, thereby greatly reducing the burden of the user to find the target vascular image, thereby improving the diagnostic efficiency of angiography.

[0091] In one embodiment, optionally, the angiography device further comprises a catheter for injecting a contrast agent into the target blood vessel.
