Embodiment 1,
An embodiment of the present application provides a method for loading a medical image, which is applied to a device for loading a medical image, as shown in fig. 1, and fig. 1 is a flowchart of a method for loading a medical image provided in an embodiment of the present application. The medical image loading method comprises the following steps:
step 101, loading a target medical image in a first image guidance phase.
It should be noted that the first image guiding stage may be an image guiding stage of the diagnosis and treatment process, for example, the first image guiding stage may be a positioning stage. The target medical image may be any one of medical images, which may be a medical image to be loaded, and may be a CT image, a magnetic resonance (english: magnetic Resonance, MR) image, for example; of course, the description is intended to be illustrative only and is not to be taken as limiting the present application. The loading of the target medical image may be a process of reading the target medical image into a cache/memory of a loading device of the medical image, so that after the target medical image is loaded, the target medical image occupies a certain storage space in the cache/memory, which may be understood as a process of storing the target medical image in the cache/memory, and the loading of the target medical image may include storing. Illustratively, the target medical image may be acquired from a radiation therapy planning system (English: treatment Planning System, TPS) server and loaded into memory/cache.
The loading of the target medical image may be a direct loading of the target medical image or a loading of a treatment plan containing the target medical image, e.g. loading the target medical image in the first image guidance phase comprises: a treatment plan is loaded during a first image-guided phase, the treatment plan including a target medical image.
Here, a process of loading a target medical image will be described in detail by listing three application scenarios:
optionally, in the first application scenario, loading the target medical image in the first image guidance phase includes: in a first image guidance phase, the target medical image is loaded into a storage unit of the memory and stored into 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 to the memory for storage. In the first image guidance stage, when the target medical image is needed to be utilized, the target medical image is loaded into a memory, and subsequent operations can be performed by utilizing the target medical image after the target medical image is loaded.
Optionally, in combination with the first application scenario, in the second application scenario, the first image guidance phase may be a swing image guidance phase, and loading the target medical image in the first image guidance phase includes: in the wobble image guidance phase, the target medical image is loaded into a memory unit of a memory. In the present application, the positioning image guiding stage may be a positioning stage before a treatment process, specifically, in the positioning stage, a position of the target object imaged in the real-time medical image (i.e., a current position of the target object) may be compared with a position of the target object imaged in the target medical image (i.e., a position of the target object in a treatment plan), and the position of the target object is adjusted so that the position of the target object coincides with a position when the plan is made. In the phase of image guiding, after the target medical image is loaded to the storage unit of the memory, the target medical image can be displayed, so that the user can observe conveniently, and the offset of the target object in the real-time medical image relative to the target object in the target medical image can be determined, so that the positioning can be adjusted. The target object may be a human skeleton, a human tissue, a tumor, a gold-labeled marker, etc., which is not limited in this application.
Optionally, in a third application scenario, loading the target medical image in the first image guidance phase includes: a first process is established and a target medical image is loaded. The target medical image may be loaded by running a first process, which may be the process of the first image guidance stage executing the loading of the target medical image, or may be the process including the loading of the target medical image, which is not limited in this application.
Step 102, acquiring a storage address of the loaded target medical image.
The memory address may be a memory address occupied by the target medical image during loading.
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: and acquiring the storage address of a storage unit occupied by the target medical image in the memory.
And step 103, calling the target medical image in a second image guiding stage according to the loaded storage address of the target medical image.
The second image guidance phase follows the first image guidance phase, which may be a real-time image guidance phase during treatment, i.e. during radiation treatment. Of course, this is only an exemplary illustration.
In the second image guiding stage, according to the storage address of the target medical image after being loaded in the first image guiding stage, the target medical image can be directly called without reloading; or after the target medical image is loaded in the first image guiding stage, the target medical image is not deleted, so the target medical image loaded in the first image guiding stage can be directly called in the second image guiding stage without reloading. The user may preset whether to load the target medical image in the second image guidance phase, or the user may control in real time whether to load the target medical image in the second image guidance phase, or the user may control whether to perform the second image guidance phase, as described herein by way of two examples:
optionally, in one example of the present application, the method further includes, before invoking the target medical image in the second image guidance phase, according to the loaded storage address of the target medical image: acquiring indication information for executing a second image guidance stage; correspondingly, according to the storage address of the target medical image after being loaded, the target medical image is called in a second image guiding stage, which comprises the following steps: and when the indication information is determined to be acquired, calling the target medical image in a second image guiding stage according to the storage address of the loaded target medical image. It should be noted that, in this example, the instruction information for executing the second image guidance phase may be generated according to a real-time operation of the user, and whether to load the target medical image in the second image guidance phase is determined according to the instruction information, so that the user control is more flexible.
Optionally, in another example of the present application, the treatment plan includes a target medical image, further including indication information to perform a second image guidance phase; according to the storage address of the target medical image after being loaded, the target medical image is called in a second image guiding stage, which comprises the following steps: and when the indication information is acquired in the treatment plan, calling the target medical image in a second image guiding stage according to the storage address of the loaded target medical image. In this example, the indication of the execution of the second image guidance phase is preset in the treatment plan, and no further action is required by the user. If the second image guidance phase is not included in the process of planning the treatment, the target medical image may not be loaded. Whether the second image guidance phase is included or not may be set by the user himself during the treatment planning.
Optionally, in combination with the third application scenario in step 101, in an embodiment of the present application, invoking the target medical image in the second image guidance stage according to the loaded storage address of the target medical image includes: and establishing a second process, calling the target medical image according to the storage address of the target image loaded in the first process, wherein the second process is different from the first process. The second process can be a process for calling the target medical image, because the first process does not delete the target image after the target image is loaded, the second process can directly call the target medical image according to the memory address of the target image after the target image is loaded in the first process, and repeated loading is not needed.
Based on the method for loading the medical image described in the above steps 101-103, the first image guiding stage is a swing image guiding stage, the second image guiding stage is a treatment image guiding stage, and a specific application scenario is listed to illustrate the method for loading the medical image, as shown in fig. 2, and fig. 2 is a schematic application scenario diagram of the method for loading the medical image according to the first embodiment of the present application. As shown in fig. 2, fig. 2 shows a medical image loading device 20, a diagnosis and treatment device 21, and a TPS server 22, where 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, a detector 212, and the like.
The target object to be positioned/treated may be located between an imaging source 211 and a detector 212, the target object may be an organ of a human body or a part of a human body, the imaging source 211 emits radiation to the target object, and the detector 212 receives the radiation for imaging, so as to obtain a real-time medical image of the target object.
In the swing image guiding stage, the medical image loading device 20 loads the target medical image, which may be obtained from the TPS server 22, and the target medical image is loaded into the memory/cache of the medical image loading device 20, or the target medical image may be first transferred to the hard disk of the medical image loading device 20, and the medical image loading device 20 loads the target medical image into the memory or cache from the hard disk. Performing positioning adjustment according to the real-time medical image of the target object and the target medical image, after the positioning image guiding stage is finished, the target medical image loaded in the memory or the buffer memory is not deleted, is kept in the memory or the buffer memory,
after entering the treatment image guiding stage, the diagnosis and treatment device 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 store the real-time medical image in a memory or a cache, and call the target medical image according to the storage address of the loaded target medical image, and compare the target medical image with the real-time medical image, so that the real-time image guiding is realized.
According to the medical image loading method, a target medical image is loaded in a first image guiding stage; acquiring a storage address of a target medical image after loading; and calling the target medical image in the second image guiding stage according to the storage address of the loaded target medical image. Because the target medical image is loaded in the first image guiding stage, and the target medical image loaded in the first image guiding stage is directly called in the second image guiding stage, the target medical image does not need to be reloaded, the situation that the medical image is repeatedly loaded in different image guiding stages is avoided, the waiting time of a user is reduced, and the user experience is improved.
