Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In the present embodiment, the image processing involved may be loading and rendering processing of an image sequence such as a medical image sequence, a mechanical image sequence, a civil construction image sequence, an archaeological image sequence, a game image sequence, or the like. For example, the mechanical image sequence may be an image sequence consisting of mechanical images of different parts of the same part; the medical image sequence may be understood as a sequence of multi-slice images generated by a medical scanning device such as a CT device, an MRI device (Magnetic Resonance Imaging), a DBT device (Digital Breast three-dimensional tomography), etc., scanning a subject, for example, a CT image sequence, a DBT image sequence, etc. It should be noted that, in this embodiment, a medical image sequence is taken as an example for description, and processing methods of other image sequences are similar and are not described again.
The image processing method provided by the application can be applied to the application environment shown in fig. 1. The PACS (Picture Archiving and Communication Systems) server 102 is connected to at least one medical scanning device 103 and the image processing workstation 101, and the connection mode may be network connection or DICOM (Digital Imaging and Communications in Medicine) connection. The PACS server can acquire and store a medical image sequence generated by the medical scanning equipment in a digital form, and can also send the medical image sequence to an image processing workstation; the image processing workstation can perform rendering processing such as size adjustment, window level adjustment, smoothing, sharpening and the like on the medical images in the medical image sequence and display the medical images, a user (such as a doctor) can directly read the rendered medical images on the image processing workstation, and the image processing workstation can be various graphic workstations or other computer equipment capable of processing the medical images; the medical scanning device may be a CT device, an MRI device, a DBT device, etc. Of course, the image processing method provided by the present application may also be applied in an application environment where the medical scanning device 103 and the image processing workstation 101 are directly connected, and a PACS server is not required; in short, the present embodiment does not limit this.
In one embodiment, as shown in fig. 2, there is provided an image processing method, which is described by taking the method as an example applied to the image processing workstation in fig. 1, and comprises the following steps:
s201, receiving an image reference instruction input by a user in the process of loading an image sequence to a memory; the image review instruction includes at least one image identification.
Generally, the image processing workstation may receive at least one medical image sequence transmitted by the medical scanning device and store the medical image sequence in a hard disk or other storage device of the image processing workstation, and then load the medical image sequence in the hard disk into a memory of the image processing workstation according to a preset loading order and render the medical image sequence according to a preset rendering order. For example, when there are a plurality of medical image sequences in the hard disk, the preset loading order may be an arrangement order of sequence identifiers of the medical image sequences, an arrangement order according to generation times of the medical image sequences, or the like, for the plurality of medical image sequences; for a plurality of medical images in the same medical image sequence, the preset loading sequence may be an arrangement sequence of image identifiers of the medical images in the medical image sequence, or an arrangement sequence of generation times of the medical images in the medical image sequence, or the like; the preset rendering order may be the same as the preset loading order.
Since the data size of the medical image is generally large, the medical image sequence generally includes a plurality of medical images, and therefore the loading time of the medical image sequence is relatively long. For example, for a medical image sequence composed of 8 medical images with image identifiers 21, 22 … … 27, and 28, respectively, which is in the process of loading, when a user wants to view a target medical image with an image identifier of interest 25 in advance, the user may select a plurality of image identifiers (or may further include associated image thumbnails, etc.) in the display interface of the image processing workstation during loading, select at least one image identifier, and the image processing workstation may receive an image review instruction triggered by the user's selection of the at least one image identifier, where the image review instruction includes the at least one image identifier.
S202, judging whether the target image associated with the image identifier is loaded in the memory completely.
When the medical images are loaded in the memory of the image processing workstation, the image processing workstation can acquire the image identifiers of the loaded medical images, so that whether the medical images are loaded in the memory can be judged; therefore, when the image reference instruction is received, the image processing workstation can judge whether the target medical image associated with the image identifier is completely loaded in the memory according to the image identifier in the image reference instruction. When the image reference instruction includes a plurality of image identifiers, the image processing workstation may determine whether the target medical image respectively associated with each of the plurality of image identifiers is completely loaded in the memory.
S203, if the target image is not loaded in the memory completely, the target image is preferentially loaded in the memory, and the loaded target image is rendered.
If the target medical image is not loaded in the memory completely, in order to enable the user to view the rendered target medical image as soon as possible, the image processing workstation may preferentially load the target medical image from the hard disk into the memory and render the loaded target medical image, that is, the image processing workstation is in a processing flow of loading and rendering the image medical sequence.
It can be understood that, in this embodiment, both the Central Processing Unit (CPU) and the image processor (GPU) in the image processing workstation can render the target medical image, although the rendering speed of the image processor is faster, when the target medical image is not completely loaded in the memory, it means that if the target medical image is rendered by the image processor, the target medical image needs to be loaded into the memory from the hard disk and then loaded into the video memory from the memory before rendering, compared with the rendering by the central processing unit, the target medical image needs to be loaded into the memory from the hard disk only before rendering, the loading takes longer time and the resource consumption is more; therefore, optionally, the rendering the target medical image after the loading is completed may include: and calling a central processing unit to render the target medical image in the memory. Therefore, the target medical image which is not loaded in the memory is rendered by the central processing unit, and the waiting time of the user is shorter than that of the image processor.
And S204, displaying the rendered target image.
In this embodiment, the image processing workstation may display the rendered target medical image for the user to read after the rendering is completed; the user can read the film more efficiently according to the rendered target medical image.
In the image processing method of the embodiment, when the user wants to view a required target image, the image processing workstation may preferentially load the rendering target image and display the rendered target medical image after receiving an image viewing instruction for the target image input by the user, so that the waiting load time of the target image is avoided, and therefore, the waiting time of the user is reduced.
In an embodiment, referring to fig. 3, on the basis of the image processing method shown in fig. 2, if the target image is completely loaded in the memory, this embodiment may further include a step of further determining whether the target image is completely loaded in the video memory, and performing corresponding processing, which may specifically include:
s301, if the target image is loaded in the memory completely, judging whether the target image is loaded in the video memory completely.
Generally, when the medical image sequence is completely loaded in the memory, the image processing workstation will automatically load the medical image sequence from the memory into the video memory. In this embodiment, if the target medical image is completely loaded in the memory, the image processing workstation needs to further determine whether the target medical image is completely loaded in the video memory. Similarly, since the image processing workstation can know the image identifier of the loaded medical image every time when a medical image is completely loaded in the video memory of the image processing workstation, it can be determined whether each medical image is completely loaded in the video memory.
S302, if the target image is loaded in the video memory, calling a graphics processor to render the target image in the video memory.
It can be understood that, if the target medical image is completely loaded in the display memory, the image processing workstation may invoke the graphics processor to render the target medical image in the display memory, and the rendering speed is faster than that of the central processor to render the target medical image. If the target medical image is not loaded in the video memory, the image processing workstation can call the CPU to render the target medical image in the memory, and can also load the target medical image in the memory into the video memory and call the GPU to render the target medical image in the video memory. Optionally, if the target medical image is not completely loaded in the video memory, the image processing workstation may obtain the data size of the target medical image; and if the data size of the target medical image is larger than a preset data size threshold, calling a CPU (Central processing Unit) to render the target medical image in the memory. When the target medical image is too large, more resources are consumed for loading the target medical image from the memory into the video memory, and more time is needed for loading the target medical image from the memory into the video memory, which is not enough to make up for the advantage that the GPU is faster than the CPU in rendering, that is, in total, the user is required to wait for a longer time.
In short, in the image processing method of the embodiment, when the target medical image is completely loaded in the video memory, the graphics processor is called to render the target medical image in the video memory, so that the rendering speed is faster.
In an embodiment, referring to fig. 4, on the basis of the image processing method shown in fig. 2, if the target image is completely loaded in the memory, this embodiment may further include a step of further determining whether a target image sequence to which the target image belongs is completely loaded in the video memory, and performing a corresponding efficient processing operation, which may specifically include:
s401, if the target image is completely loaded in the memory, judging whether the target image sequence associated with the image identifier is completely loaded in the video memory;
s402, if the target image sequence is loaded in the video memory, calling a graphics processor to render the target image in the video memory.
It should be noted that, generally, when the image processing workstation loads the medical image sequence from the memory into the video memory, the medical images may be loaded one by one, or the entire medical image sequence may be loaded. When medical images are loaded in the video memory one by one, the image processor can take each medical image as a separate object and create a corresponding two-dimensional texture for rendering; when the whole medical image sequence is loaded, the image processor can take the whole medical image sequence as an object to create a three-dimensional texture for rendering, obviously, the rendering efficiency is higher and the occupied resources are less when the image processor loads the whole medical image sequence.
The image processing workstation may store therein an association relationship between each sequence identifier and each image identifier, for example, the sequence identifier 2 may be associated with image identifiers such as 21 and 28. The image processing workstation may obtain a target sequence identifier associated with the image identifier in the image review instruction, and obtain a current sequence identifier of the medical image sequence currently being loaded, and when it is determined that the target sequence identifier is the same as the current sequence identifier, it means that the medical image sequence being loaded is the target medical image sequence in which the target medical image is located. At this time, the image processing workstation may only adjust the loading sequence of each medical image in the loaded medical image sequence, for example, may load the current medical image in the loading process first, and load the target medical image after the current medical image is loaded; the loading of the current medical image can be suspended, and the target medical image is loaded into the memory from the hard disk; or other preferential loading methods, which is not limited by the embodiment.
In one embodiment, before the preferentially loading the target image into the memory, the method may further include: judging whether the target image sequence associated with the image identifier is the loaded image sequence; and if not, preferentially loading the target image sequence. The image processing workstation may obtain a target sequence identifier associated with the image identifier in the image lookup instruction, and obtain a current sequence identifier of the image sequence currently being loaded, and when it is determined that the target sequence identifier is different from the current sequence identifier, which means that the image sequence being loaded is not the target image sequence in which the target image is located, the image processing workstation may preferentially load the target image sequence, for example, may suspend the currently loaded image sequence, and load the target image sequence from the hard disk into the memory.
Optionally, the preferentially loading the target image into the memory may include: setting the loading priority of the target image as the highest priority; and loading the images in the target image sequence associated with the image identifier into the memory according to the loading priority ranking order. The image processing workstation can mark each medical image in each target medical image sequence with a loading sequence, and mark the target medical image with the highest loading priority, so that the target medical image can be loaded preferentially when the target medical image sequence is loaded according to the loading priority ranking sequence; therefore, the image processing workstation can avoid excessively changing the preset loading sequence, and can complete the preferential loading of the target medical image only by changing the loading priority. Similarly, the image processing workstation may further set the rendering priority of the target medical image to the highest priority, and render the medical images in the rendering priority order.
It can be understood that, when the image lookup instruction includes a plurality of image identifiers, the image processing workstation may respectively determine whether loading of the target medical image associated with each image identifier in the memory is completed; and the steps of S203-S204, and S301-302 or S401-S402 described above may be performed for different determination results of different target medical images, respectively. In order to avoid conflict, the image processing workstation may further set a processing priority for each target medical image, and thus the image processing workstation may preferentially execute the image processing method described in this embodiment on the target medical image with the high processing priority. For example, the image processing workstation may set the processing priorities according to an order of the data sizes of the target medical images from small to large, and the higher the priority in the top order, so that the target medical images with a small data size may be preferentially loaded, rendered and displayed.
In summary, in the process of loading the target image sequence into the memory, the image processing workstation in this embodiment may select different loading and rendering modes according to different loading states of the target image corresponding to the image identifier in the image lookup instruction input by the user, so as to implement efficient loading and rendering processing and reduce the user waiting time, specifically:
when the target image is not loaded in the memory completely, the image processing workstation can preferentially load the target image into the memory from the hard disk and call the CPU to render the target image in the memory;
when the target image is loaded in the memory and is not loaded in the video memory, the image processing workstation can call the CPU to render the target image in the memory;
when the target image is loaded in the memory completely, then the target image is automatically loaded in the video memory and the loading is completed, the image processing workstation can call the GPU to render the target image in the video memory;
when the target image sequence is completely loaded in the memory, and then the target image sequence is automatically loaded in the video memory and the loading is completed, the image processing workstation can call the GPU to render the target image in the video memory.
Referring to fig. 5, the image processing workstation may include: the image processing method is described in the aspect of processing timing from another aspect, and specifically includes:
s501, an image loading module loads a medical image sequence from a hard disk of an image processing workstation into a memory of the image processing workstation;
s502, in the loading process of the medical image sequence in the step 501, the interface interaction module receives an image reference instruction triggered by a user;
s503, the interface interaction module sends a request for the target medical image associated with the image identifier to the image rendering module according to the image identifier in the image consulting instruction;
s504, the image rendering module receives and forwards a request aiming at the target medical image to the image loading module;
s505, the image loading module preferentially loads the target medical image when the target medical image is not loaded;
s506, the image loading module returns the loaded target medical image to the image rendering module;
s507, the image rendering module performs rendering processing on the target medical image;
s508, after the image rendering module finishes rendering the target medical image, the image rendering module sends a rendering result to the interface interaction module, namely the rendered target medical image;
s509, the interface interaction module receives and displays the rendered target medical image.
Likewise, the image processing workstation may perform the processing of other medical images according to the above steps or parts of the steps. It should be noted that each module may be a hardware entity in the image processing workstation, for example, the image loading module may be a DMA (Direct Memory Access), the image rendering module may be a central processing unit or a graphics processing unit, and the interface interaction module may be a touch screen display or the like.

The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
