[0002] In the field of medical technology, it is usually necessary to take medical images of patients for doctors to observe. For example, computer tomography (CT) uses radiation to irradiate the target object and uses a detector to receive the radiation that passes through the target object to perform imaging. It can perform cross-sectional scanning of the target object (for example, the human body), with fast scanning time and clear images. Taking CT images as an example, the image guidance in the positioning image guidance stage and the image guidance in the treatment image guidance stage are two separate programs. When the patient needs to be positioned, the image guidance program in the positioning image guidance stage is started and the CT image is loaded; if the patient needs real-time medical image guidance during radiotherapy after the positioning is completed, the image guidance program in the treatment image guidance stage is started and the CT image needs to be reloaded. However, CT images are usually large, and users need to wait for the image to be loaded, which takes a long time and has a poor user experience. Summary of the invention

[0023] The specific implementation of the embodiment of the present invention is further described below in conjunction with the accompanying drawings of the embodiment of the present invention.

[0024] Embodiment 1

[0025] Embodiment 1 of the present application provides a method for loading a medical image, which is applied to a loading device for a medical image, such as Figure 1 As shown, Figure 1A flowchart of a method for loading a medical image provided in an embodiment of the present application. The method for loading a medical image comprises the following steps:

[0026] Step 101: Load a target medical image in a first image-guided phase.

[0027] It should be noted that the first image-guided stage can be an image-guided stage of the diagnosis and treatment process, for example, the first image-guided stage can be a positioning stage. The target medical image can be any medical image, and the target medical image can be a medical image to be loaded. For example, the target medical image can be a CT image or a magnetic resonance (MR) image; of course, this is only an exemplary description and does not mean that the present application is limited to this. Loading the target medical image can be a process of reading the target medical image into the cache / memory of the loading device of the medical image. Therefore, after loading the target medical image, the target medical image occupies a certain storage space in the cache / memory. It can be understood that the target medical image is stored in the cache / memory, and loading the target medical image can include a storage process. For example, it can be to obtain the target medical image from the radiation therapy planning system (TPS) server and load the target medical image into the memory / cache.

[0028] The target medical image may be loaded directly, or a treatment plan including the target medical image may be loaded. For example, loading the target medical image in the first image guidance stage includes: loading the treatment plan in the first image guidance stage, wherein the treatment plan includes the target medical image.

[0029] Here, three application scenarios are listed to explain in detail the process of loading target medical images:

[0030] Optionally, in the first application scenario, loading the target medical image in the first image guidance stage includes: loading the target medical image into a storage unit of a memory in the first image guidance stage, and storing the target medical image in the storage unit of the memory. It should be noted that the memory may be a buffer memory or a memory, and the process of loading the target medical image may be a process of reading the target medical image from an external device or a hard disk into the memory for storage. In the first image guidance stage, when the target medical image needs to be used, the target medical image is loaded into the memory, and after the target medical image is loaded, the target medical image can be used to perform subsequent operations.

[0031] Optionally, in combination with the first application scenario, in the second application scenario, the first image guidance stage may be a positioning image guidance stage, and loading the target medical image in the first image guidance stage includes: in the positioning image guidance stage, loading the target medical image into a storage unit of the memory. In the present application, the positioning image guidance stage may be a positioning stage before the treatment process. Specifically, in the positioning stage, the position of the target object imaged in the real-time medical image (i.e., the current position of the target object) may be compared with the position of the target object imaged in the target medical image (such as the position of the target object in the treatment plan), and the position of the target object may be adjusted so that the position of the target object coincides with the position when the plan is made. In the positioning image guidance stage, after the target medical image is loaded into the storage unit of the memory, the target medical image may be displayed for user observation, and the offset of the target object in the real-time medical image relative to the target object in the target medical image may be determined, thereby adjusting the positioning. The target object may be a marker such as human bones, human tissues, tumors, gold labels, etc., and the present application does not limit this.

[0032] Optionally, in a third application scenario, loading the target medical image in the first image guidance stage includes: establishing a first process to load the target medical image. The target medical image may be loaded by running the first process, and the first process may be a process for executing the loading of the target medical image in the first image guidance stage, or may be a process including the loading of the target medical image, and this application does not limit this.

[0033] Step 102: Obtain the storage address of the loaded target medical image.

[0034] The storage address may be the storage address occupied by the target medical image during the loading process.

[0035] Optionally, in combination with the first application scenario in step 102, in an embodiment of the present application, obtaining the storage address of the target medical image after loading includes: obtaining the storage address of a storage unit occupied by the target medical image in the memory.

[0036] Step 103 : calling the target medical image in the second image guiding stage according to the storage address of the loaded target medical image.

[0037] The second image guidance stage is after the first image guidance stage, and the second image guidance stage may be a real-time image guidance stage during the treatment process, that is, real-time image guidance during the radiotherapy process. Of course, this is only an exemplary description.

[0038] In the second image guidance stage, according to the storage address of the target medical image after loading in the first image guidance stage, the target medical image can be directly called without reloading; or, after the target medical image is loaded in the first image guidance stage, the target medical image is not deleted, so the target medical image loaded in the first image guidance stage can be directly called in the second image guidance stage without reloading. The user can preset whether to load the target medical image in the second image guidance stage, or the user can control in real time whether to load the target medical image in the second image guidance stage, or the user can control whether to execute the second image guidance stage. Two examples are listed here for illustration:

[0039] Optionally, in an example of the present application, before calling the target medical image in the second image guidance stage according to the storage address of the target medical image after loading, the method further includes: obtaining instruction information for executing the second image guidance stage; correspondingly, calling the target medical image in the second image guidance stage according to the storage address of the target medical image after loading includes: when determining that the instruction information is obtained, calling the target medical image in the second image guidance stage according to the storage address of the target medical image after loading. It should be noted that in this example, the instruction information for executing the second image guidance stage can be generated according to the real-time operation of the user, and whether to load the target medical image in the second image guidance stage is determined according to the instruction information, and the user control is more flexible.

[0040] Optionally, in another example of the present application, the treatment plan includes a target medical image and also includes instruction information for executing a second image guidance phase; calling the target medical image in the second image guidance phase according to the storage address of the target medical image after loading, including: when the instruction information is obtained in the treatment plan, calling the target medical image in the second image guidance phase according to the storage address of the target medical image after loading. In this example, the instruction information for executing the second image guidance phase is pre-set in the treatment plan, and the user does not need to perform further operations. If the second image guidance phase is not included in the process of formulating the treatment plan, the target medical image may not be loaded. Whether to include the second image guidance phase can be set by the user in the process of making the treatment plan.

[0041] Optionally, in combination with the third application scenario in step 101, in one embodiment of the present application, calling the target medical image in the second image guidance stage according to the storage address of the target medical image after loading includes: establishing a second process, calling the target medical image according to the storage address of the target image after loading in the first process, and the second process is different from the first process. The second process can be a process that calls the target medical image, because the first process does not delete the target image after loading it, and the second process can directly call the target medical image according to the storage address of the target image after loading in the first process, without repeated loading.

[0042] Based on the medical image loading method described in steps 101-103 above, the first image guidance stage is the positioning image guidance stage, and the second image guidance stage is the treatment image guidance stage. As an example, a specific application scenario is listed to illustrate the medical image loading method. Figure 2 As shown, Figure 2 This is a schematic diagram of an application scenario of a method for loading medical images provided in Example 1 of the present application. Figure 2 As shown, Figure 2 A medical image loading device 20, a diagnosis and treatment device 21 and a TPS server 22 are shown. The medical image loading device 20 may be a computer with a display screen, and the diagnosis and treatment device 21 may include an imaging source 211 and a detector 212, etc.

[0043] The target object to be positioned / treated can be located between the imaging source 211 and the detector 212. The target object can be an organ or a part of the human body. The imaging source 211 emits rays to the target object, and the detector 212 receives the rays for imaging to obtain a real-time medical image of the target object.

[0044] In the positioning image guidance stage, the medical image loading device 20 loads the target medical image. The target medical image can be obtained from the TPS server 22 and loaded into the memory / cache of the medical image loading device 20, or the target medical image can be first transmitted to the hard disk of the medical image loading device 20, and the medical image loading device 20 loads the target medical image from the hard disk into the memory or cache. Positioning adjustment is performed according to the real-time medical image of the target object and the target medical image. After the positioning image guidance stage is completed, the target medical image loaded in the memory or cache is not deleted and is retained in the memory or cache.

[0045] After entering the treatment image guidance stage, the diagnostic equipment 21 images the target object to obtain a real-time medical image, and transmits the real-time medical image to the medical image loading device 20. The medical image loading device 20 can directly call the target medical image in the memory or cache according to the storage address of the target medical image after loading, and compare it with the real-time medical image, thereby realizing real-time image guidance.

[0046] The medical image loading method provided in the embodiment of the present application loads the target medical image in the first image guidance stage; obtains the storage address of the loaded target medical image; and calls the target medical image in the second image guidance stage according to the storage address of the loaded target medical image. Because the target medical image is loaded in the first image guidance stage, in the second image guidance stage, the target medical image loaded in the first image guidance stage is directly called, and there is no need to reload the target medical image, thus avoiding repeated loading of medical images in different image guidance stages, reducing user waiting time, and improving user experience.
