Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an image display method according to an embodiment of the present invention, where the embodiment is applicable to a case where an angiography device is used to perform imaging and display an imaging result, the method may be performed by an image display apparatus, the apparatus may be implemented in software and/or hardware, and the apparatus may be configured in the angiography device. The method specifically comprises the following steps:
and S110, acquiring a first blood vessel image of an imaging object acquired by the angiography device based on the first field of view parameter, and displaying the first blood vessel image.
The angiography technology is a technology for visualizing blood vessels of X-ray sequence images, and by injecting a contrast agent into blood vessels, because X-rays cannot penetrate through the contrast agent, the angiography uses the X-rays to scan and image a detected part, and the contrast agent enables the blood vessels in the detected part to form material density difference with other tissues, so that the scanned images can accurately reflect the positions and the degrees of vascular lesions.
Illustratively, 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 imaging object as an abdomen, in particular, the first view field can be used to describe a size of a region corresponding to the imaging object in the first blood vessel image. For example, assuming that the overall size of the region corresponding to the abdomen is 100 × 100, the first view range may be 100 × 100 or 30 × 50, and when the first view range is 30 × 50, the first view range includes a part of the abdomen view range. Specifically, the first magnification may be used to describe the magnification of the first blood vessel image to the imaging subject, similar to 100 times the blood vessel image. The first magnification may be a relative magnification with respect to the standard magnification or an actual magnification with respect to the image with respect to the blood vessel. If the first magnification is a relative magnification with respect to the standard magnification, when the first magnification is greater than the standard magnification, the first blood vessel image is an enlarged image with respect to the image corresponding to the standard magnification, and when the first magnification is less than the standard magnification, the first blood vessel image is a reduced image with respect to the image corresponding to the standard magnification.
In particular, the first center of field of view position may be used to describe an image center position of the first vessel image, and from the perspective of the angiographic apparatus, the first center of field of view position may be used to describe a position on the detector corresponding to a beam center position of the radiation source. Specifically, the first imaging mode includes a perspective mode or an exposure mode. 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 an actual application scenario, a user may switch the imaging mode by using a Zoom function on the angiography device.
In one embodiment, displaying a first blood vessel image comprises: and displaying the first blood vessel image in a preset display area of the display device, or displaying the first blood vessel image on the whole display interface of the display device.
And S120, determining a second visual field parameter based on the received parameter adjusting instruction and the first visual field parameter.
In this embodiment, the parameter adjustment instruction includes a scaling adjustment ratio. Specifically, when the scaling adjustment ratio is greater than one, the second magnification in the second visual field parameter is greater than the first magnification or the second visual field range is smaller than the first visual field range. When the zoom adjustment scale is less than one, the second magnification in the second visual field parameter is less than the first magnification or the second visual field range is greater than the first visual field range. From the viewpoint of the blood vessel image, when the scaling adjustment ratio is larger than one, a magnification operation is performed on the first blood vessel image. And when the scaling adjustment proportion is less than one, performing reduction operation on the first blood vessel image.
When the parameter adjustment instruction only includes the zoom adjustment ratio, if the zoom adjustment ratio is 1, the first visual field parameter is the second visual field parameter, and the subsequently obtained second blood vessel image is completely the same as the first blood vessel 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, the method further includes: and if the first visual field parameter is the same as the second visual field parameter, generating prompt information. Specifically, the prompt information may be used to prompt the user that the blood vessel image corresponding to the parameter adjustment instruction already exists. Further, the user may be prompted about the display position of the blood vessel image corresponding to the current visual field adjustment parameter. Illustratively, the prompting mode can be at least one mode of a text prompt, a voice prompt and a prompt lamp. The method includes the steps that a corresponding prompting lamp can be set for at least one display device, and if a blood vessel image displayed on the display device at present corresponds to a current parameter adjusting instruction, the prompting lamp flickers. The method has the advantages that the blood vessel images with the same visual field parameters are prevented from being displayed, waste of display positions is avoided, and the utilization rate of the display equipment is reduced.
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: a second magnification in the second field of view parameter is determined based on the zoom adjustment scale and the first magnification in the first field of view parameter. In this example, assuming that the first magnification in the first visual field parameter is 2 times and the zoom adjustment scale is 3 times with respect to the preset standard magnification, the second magnification is 6 times.
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: a second horizon in the second horizon parameter is determined based on the scaling and the first horizon in the first horizon parameter. In this case, it is exemplarily assumed that the first visual field range is 10 × 10, and the scaling ratio is 2 times, and the second visual field range is 5 × 5.
On the basis of the above embodiment, when the parameter adjustment instruction includes only the zoom adjustment scale, the second magnification and the second visual field range are calculated based on the first magnification, the first visual field range, and the zoom adjustment scale in the first visual field parameter. For example, the second center of field of view position may default to the first center of field of view position in the first field of view parameter, and the second imaging mode may default to the first imaging mode in the first field of view parameter.
On the basis of the above embodiment, optionally, the parameter adjustment instruction further 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 may customize the second view range, the second view center position, and the second imaging mode in the second view parameter, and specifically, the view adjustment range, the view adjustment center position, and the imaging adjustment mode in the parameter adjustment instruction are respectively used as the second view range, the second view center position, and the second imaging mode. The parameter adjusting instruction can be generated based on a parameter value input by a user, or generated based on a selection operation input by a displayed first blood vessel image. Illustratively, the user may effect the input of the scaling by using Zoom functionality on the angiographic device. The user can also input an image selection frame based on the first blood vessel image, and the visual field adjustment range is generated according to the size of the input image selection frame.
And 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.
In one embodiment, optionally, determining the second blood vessel image based on the second field of view parameter comprises: a second vessel image acquired by the angiography device based on the second field of view parameter is acquired. Specifically, the angiography device is controlled to acquire a second blood vessel image based on the second field of view parameter.
It should be noted that, in the embodiment of the present invention, an exemplary explanation is performed by using two blood vessel images to be displayed synchronously, and in practical applications, more blood vessel images corresponding to different field parameters can be obtained according to the image display method provided by the embodiment of the present invention, and each blood vessel image is displayed synchronously. The number of blood vessel images displayed simultaneously is not limited here.
According to the technical scheme, the second blood vessel image is determined based on the received parameter adjusting instruction while the first blood vessel image is displayed, and the second blood vessel image and the first blood vessel image are displayed synchronously, so that the problem of repeated switching display of the scanning images with different visual fields is solved, the times and the radiation quantity of repeated imaging are reduced, the service life of the angiography equipment is prolonged, the diagnosis efficiency of angiography is further improved, and the error of the diagnosis result of the angiography caused by repeated switching is reduced.
Example two
Fig. 2 is a flowchart of an image display method according to a second embodiment of the present invention, where this embodiment is further refined on the basis of the foregoing embodiment, and optionally, the synchronously displaying the second blood vessel image and the first blood vessel image includes: 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 equipment based on the changed first visual field parameter; and determining an updated second visual field parameter based on the changed first visual field parameter and the parameter adjusting instruction, and synchronously displaying the updated second blood vessel image determined based on the updated second visual field parameter and the updated first blood vessel image.
The specific implementation steps of this embodiment include:
s210, acquiring a first blood vessel image of an imaging object acquired by the angiography device based on the first field of view parameters, and displaying the first blood vessel image.
And S220, determining a second visual field parameter based on the received parameter adjusting instruction and the first visual field parameter, and determining a second blood vessel image based on the second visual field parameter.
In one embodiment, optionally, the imaging subject includes a blood vessel and a catheter inserted into the blood vessel, the second field of view parameter is determined based on the received parameter adjustment instruction and the first field of view parameter, and the method further includes: and when the scaling adjustment ratio is larger than one, acquiring a catheter tip image corresponding to the catheter in the first blood vessel image, and taking the visual field center position and the visual field range corresponding to the catheter tip image as a second visual field center position and a second visual field range in the second visual field parameter respectively.
Angiography is a technique in which a contrast medium is injected into a target blood vessel by means of catheter intervention. Specifically, in the angiography technique, a catheter is inserted into a blood vessel to inject a contrast medium into the catheter, and then the contrast medium is delivered to a specified blood vessel position through the catheter. During catheter interventions, real-time imaging of the vessel is required in order to observe the position of the catheter in the 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 by imaging the tip of the catheter.
The catheter tip image corresponding to the catheter in the first blood vessel image is obtained, specifically, the first blood vessel image is divided to obtain the catheter tip image based on a preset division rule, and the preset division rule exemplarily includes a preset image size, a preset image shape and the like. For example, the predetermined image shape may be a square, a rectangle, a circle, or an irregular shape. The preset image size may be determined according to a preset image shape, for example, when the preset image shape is a square, the preset image size may be 10mm by 10mm, and when the preset image shape is a circle, the preset image size may be 5mm in radius. Of course, the preset image size may also refer to the image area of the catheter tip image.
This has the advantage that by automatically identifying the catheter tip image in the first vessel image, the step of manually selecting the image of the region of interest is avoided. When the first blood vessel image is changed, the catheter tip image in the changed first blood vessel image can be tracked and identified in real time, so that the diagnosis efficiency of angiography in the subsequent angiography process is greatly improved.
On the basis of the foregoing embodiment, optionally, determining the second blood vessel image based on the second field of view parameter includes: acquiring a second blood vessel image acquired by the angiography device based on the second field of view parameter; or, when the scaling adjustment scale is larger than one, determining a reference blood vessel image in the first blood vessel image based on the second visual field center position and the second visual field range in the second visual field parameter, and determining a second blood vessel image based on the second magnification in the second visual field parameter and the reference blood vessel image.
And whether the scaling adjustment proportion is larger than one or smaller than one, the angiography equipment can be controlled to acquire a second blood vessel image based on the second field of view parameter. In particular, when the scaling adjustment ratio is smaller than one, it is indicated that the reduction operation is performed on the first blood vessel image, and at this time, the second field of view range is generally larger than the first field of view range, that is, the first blood vessel image does not include all image information required by the second blood vessel image, and at this time, the angiography apparatus needs to be controlled again to acquire the second blood vessel image based on the second field of view parameters. In another embodiment, when the scaling ratio is larger than one, it is stated that the zooming operation is performed on the first blood vessel image, and the first blood vessel image generally contains all image information required by the second blood vessel image. Of course, there may be a case where the first blood vessel image does not usually include all image information required for the second blood vessel image, for example, when the center position of the second field of view is a boundary point of the first blood vessel image and the second field of view range is not 0, a method of controlling the angiography apparatus to acquire the second blood vessel image based on the second field of view parameter may also be adopted. In this embodiment, taking the example that the first blood vessel image includes all image information required by the second blood vessel image, the reference blood vessel image includes all image information required by the second blood vessel image, and the magnification corresponding to the reference blood vessel image is the first magnification, so that the reference blood vessel image needs to be magnified based on the second magnification in the second visual field parameter to obtain the second display image. The algorithm for performing the enlarging operation includes, but is not limited to, at least one of a nearest neighbor interpolation algorithm, a bilinear interpolation algorithm, and a higher order interpolation algorithm.
The method has the advantages that the reference blood vessel image is directly intercepted in the first blood vessel image, and the second blood vessel image is directly obtained based on the reference blood vessel image and the second visual field parameter, so that the repeated imaging times and the radiation quantity are further reduced, and the service life of the angiography device is prolonged.
And S230, synchronously displaying the second blood vessel image and the first blood vessel image.
In one embodiment, optionally, displaying the second blood vessel image synchronously with the first blood vessel image includes: and simultaneously displaying the second blood vessel image and the first blood vessel image. This has the advantage of avoiding the user from repeatedly switching between displaying the first blood vessel image and the second blood vessel image.
And S240, when the 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.
And S250, determining and updating the second visual field parameter based on the changed first visual field parameter and the parameter adjusting instruction.
Under the condition that the parameter adjusting instruction is not changed, when the first visual field parameter changes, the first blood vessel image also changes, and meanwhile, the second visual field parameter changes along with the first visual field parameter, so that the updated second visual field parameter is obtained.
And 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.
On the basis of the foregoing embodiment, optionally, displaying the second blood vessel image in synchronization with the first blood vessel image includes: displaying the second blood vessel image in a display area different from the first blood vessel image on a display device corresponding to the first blood vessel image; or, the second blood vessel image is displayed on a different display device than the first blood vessel image. Specifically, in an embodiment, the display interface of the same display device includes at least two regions for displaying images, where one of the regions is used for displaying a first display image and the other region is used for displaying a second display image. In another embodiment, the angiographic device comprises at least two display devices, one display device for displaying the first display image and the other display device for displaying the second display image.
Of course, when both the first visual field parameter and the second visual field parameter change, the obtained updated first blood vessel image and the updated second blood vessel image may also be displayed in different display areas of the display device, or may also be displayed on different display devices.
According to the technical scheme of the embodiment, the updated second visual field parameter is determined based on the changed first visual field parameter and the parameter adjusting instruction, the updated second blood vessel image determined based on the updated second visual field parameter and the updated first blood vessel image are synchronously displayed, the step that a user re-determines the second blood vessel image when the first blood vessel image is changed is solved, the diagnosis efficiency of angiography is improved, and meanwhile, the positioning error caused by human factors in the repeated confirmation process is avoided

Example four
Fig. 4 is a schematic structural diagram of an angiography device according to a fourth embodiment of the present invention, where the fourth embodiment of the present invention provides a service for implementing the image display method according to any of the above embodiments of the present invention, and the image display apparatus according to the third embodiment of the present invention may be configured.
The angiographic apparatus comprises an imaging assembly 40, at least one display device 41 and a controller 42, wherein the imaging assembly 40 is configured to acquire a first vessel image based on a first field of view parameter; a display device 41 for displaying the first blood vessel image and the second blood vessel image; the controller 42 includes one or more processors and memory storing one or more programs that, when executed by the one or more processors, cause the one or more processors to implement the image display method as in any of the above embodiments.
In one embodiment, imaging assembly 40 optionally includes an X-ray source and a detector. The X-ray source is used for emitting X-rays; a detector for generating a first blood vessel image from the received X-rays.
In one embodiment, the X-ray source optionally includes an X-ray high voltage generator and an X-ray tube. The high-frequency inversion high-voltage generator is divided into a continuous high-frequency inversion high-voltage generator and a computer-controlled pulse high-frequency inversion high-voltage generator, wherein pulse waves of the continuous high-frequency inversion high-voltage generator during pulse acquisition need to be generated by means of grid switch control in an X-ray bulb tube. Wherein, the X-ray bulb tube can receive high-frequency high-voltage output so as to excite and generate X-rays. The specification parameters of the X-ray bulb tube comprise two structural parameters and electrical parameters. The former refers to various parameters determined by the structure of the X-ray bulb tube, such as the inclination angle of the target surface, the effective focus, the overall dimension, the weight, the filtration equivalent of the tube wall, the anode rotation speed, the working temperature, the cooling form and the like. The electrical parameters refer to the specification data of the electrical performance of the X-ray tube, such as filament heating voltage and current, maximum tube voltage, tube current, maximum exposure time, maximum allowable power, anode heat capacity and the like. The X-ray bulb tube is characterized by small focus, high heat capacity, high load, high rotating speed and high heat dissipation rate. Exemplarily, the X-ray bulb tube can be manufactured by adopting a liquid metal bearing technology, so that the abrasion of a bearing of a common bulb tube under the condition of high rotating speed can be avoided, the heat dissipation efficiency is increased, the continuous load bearing capacity of the X-ray bulb tube is improved, the service life of the bulb tube is prolonged, the intrinsic noise of equipment is reduced, and the signal-to-noise ratio of an image is improved.
In one embodiment, optionally, the detector comprises a flat panel detector.
Specifically, when the angiography device includes at least two display devices 41, the placement relationship between the display devices and the placement positions of the display devices may be selected according to the usage habits of the user. When blood vessel images with different magnifications are displayed on at least two display devices 41, the magnification levels of the blood vessel images corresponding to the different display devices 41 may be preset, and illustratively, the magnification levels corresponding to the display device a, the display device B, and the display device C respectively are sequentially reduced, that is, the blood vessel image with the largest magnification is displayed on the display device a, and the blood vessel image with the smallest magnification is displayed on the display device C. The advantage of such a configuration is that if the correspondence between the blood vessel images and the display devices is not set, in the case of many display devices, when the user wants to view the target blood vessel image, the user needs to view the blood vessel images on each display device one by one to find the required target blood vessel image, thereby increasing the burden of the user in finding the target blood vessel image. And the corresponding relation between the blood vessel image and the display equipment is set, and the user can search the target blood vessel image according to the corresponding relation, so that the burden of the user for searching the target blood vessel image is greatly reduced, and the diagnosis efficiency of angiography is improved.
In one embodiment, the angiographic device further optionally comprises a catheter for injecting contrast agent into the target vessel.

In some instances, the memory may further include memory remotely located from the processor, which may be connected to the angiographic device over a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.
In one embodiment, the angiographic apparatus further optionally includes an input device for receiving input numeric or character information and generating key signal inputs relating to user settings and function controls of the angiographic apparatus.
Through the angiography device, the problem of repeatedly switching and displaying the scanning images with different visual fields is solved, the times and the radiation quantity of repeated imaging are reduced, the service life of the angiography device is prolonged, the angiography diagnosis efficiency is further improved, and the angiography diagnosis result error caused by repeated switching is reduced.
