The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, the present application provides an image processing system, comprising: the file receiving module 11, the metadata module 12, the data segmentation module 13, and at least one file storage module 14. The file receiving module 11 is configured to decompose the received image file to obtain meta information and image data of the image file, send the meta information to the meta data module 12, and send the image data to the data segmentation module 13; the data segmentation module 13 is configured to perform block processing on the image data to obtain at least two image data blocks, and send the at least two image data blocks to different file storage modules 14 respectively; each file storage module 14 is configured to store the received image data block, and send address information of the file storage module and an identifier of the image data block to the metadata module 12; the metadata module 12 is used for encrypting and storing the metadata, and associating and storing the metadata with the received address information of each file storage module and the identifier of each image data block.
In this embodiment, the image is a medical image obtained by a medical Imaging device, and the medical Imaging device includes a Computed Tomography (CT) device, a Magnetic Resonance Imaging (MRI) device, an X-Ray Imaging (XR) device, a Molecular Imaging device, an ultrasound device, and a multi-modality medical Imaging device combined with the above devices.
The image file is a Digital Imaging and Communications in Medicine (DICOM) file. The meta information (i.e. Tag information of the DICOM file) includes: image information, such as image width, height and data transmission format, and patient information, such as patient name, patient birthday, case hospital, case department, and description of illness state; the image data is image data of a patient in the meta information.
The file receiving module 11, the metadata module 12, and the data splitting module 13 may be respectively disposed on different servers to form a server cluster, or may be disposed on a single server; the file storage modules 14 may be respectively disposed on different servers to form a server cluster, or may be disposed on a single server.
Optionally, the data segmentation module 13 may be specifically configured to perform block fault-tolerant coding on the received image data to obtain at least two image data blocks.
In this embodiment, the client 10 may be any type of imaging device, and may also be any type of user terminal capable of acquiring an image file. When the client 10 acquires an image file, the image file may be uploaded to a file receiving module 11 in the image processing system, the file receiving module 11 may decompose or split the image file by analyzing the image file when receiving the image file, specifically, may analyze the meta information and the image data from the image file, then send the meta information and the image data to a meta data module 12 and a data segmentation module 13, respectively, the meta data module 12 may encrypt the meta information by using a preset encryption algorithm after receiving the meta information, and the data segmentation module 13 may perform block segmentation on the image data after receiving the image data to obtain a plurality of image data blocks, and perform coding operation (e.g., fault-tolerant coding) on each image data block to identify each image data block. Then, the data segmentation module 13 sends the plurality of image data blocks to the plurality of file storage modules 14, each file storage module 14 stores one image data block correspondingly, optionally, each file storage module 14 may also store a plurality of image data blocks correspondingly, and this is not limited here, as long as part or all of the plurality of image data blocks are stored separately, rather than all of them are stored in one file storage module 14 in a centralized manner. After each file storage module 14 stores the corresponding image data block, it may obtain its own address information, such as an IP address, and then feed back its own address information and the identifier of the image data block stored therein to the metadata module 12, so that after receiving the address information and the identifier fed back by each file storage module 14, the metadata module 12 may further determine the corresponding metadata according to the identifier of the image data block, and associate and store the metadata with the address information of each file storage module 14 and the identifier of the image data block, so that the client 10 may call when reading the image file composed of each image data block.
The image processing system provided by the above embodiment realizes efficient storage of image files, wherein the file receiving module does not immediately encrypt and store the entire image file after receiving the image file uploaded by the client, but decomposes the image file and encrypts only the meta information obtained after decomposition. Because the meta-information usually represents the private information of the patient and the occupied data volume is very small, the encryption of the meta-information can prevent the leakage of the private information of the patient, and the private information of the patient represented by the image data is less, so that the influence of the leakage of the private information on the patient can not be caused even if the image data is leaked, and the occupied data volume of the image data is very large, and if the image data is encrypted, the storage efficiency of the whole image file is extremely low, therefore, the processing system of the image improves the storage efficiency of the whole image file by only encrypting the meta-information. In addition, because the image data is split into a plurality of image data blocks and distributed to different file storage modules for storage, even if part of the image data blocks are leaked, the whole image file is not leaked, the possibility of leakage of the whole image file is reduced, and the safety of image file storage is improved.
Moreover, after the image file is stored, if the image file needs to be subjected to information preview or information modification, only the meta information of the meta data module needs to be read, modified and stored, so that the efficiency and the resource occupation are improved.
In an application environment, the metadata module 12 is further configured to send a message of successful storage to the client 10 after associating and storing the metadata with the address information of each file storage module 14 and the identifier of each image data block. After the metadata module 12 associates and stores the metadata with the address information of each file storage module and the identifier of each image data block, it indicates that the image file uploaded to the file receiving module 14 by the client 10 has been safely stored, at this time, the metadata module 12 may feed back a message of successful storage to the client 10 to inform the user of the client 10 that the safe storage has been completed, and the user may retrieve the metadata at any time.
Referring to fig. 2, the present application provides an image processing system, which further includes, on the basis of the system shown in fig. 1: the compression module 15 and the compression module 14 are configured to compress the received image data to obtain compressed image data, and send the compressed image data to the data segmentation module 13, so as to instruct the data segmentation module 13 to perform block processing on the compressed image data to obtain at least two image data blocks.
The compression module 15 may be disposed on a server, and is dedicated to compressing image data. Optionally, the compression module 15 may also be disposed on the same server as the data segmentation module 13, and configured to segment the compressed image data after compressing the image data.
In this embodiment, when the client 10 obtains an image file, the image file may be uploaded to the file receiving module 11, the file receiving module 11 decomposes the image file to obtain meta information and image data, then the meta information is sent to the metadata module 12, the image data is sent to the compression module 15, after receiving the image data, may compress the image file by using a professional compression algorithm with a high compression ratio to obtain compressed image data, and then send the compressed image data to the data splitting module 13, so that the data splitting module 13 splits the compressed image data, and performs coding operation on all split blocks to obtain a plurality of split image data blocks. Then, the data segmentation module 13 sends the plurality of image data blocks to the plurality of file storage modules 14 for storage. Because the image file can be compressed and stored by adopting a compression mode with high compression ratio in the implementation, the storage space can be effectively saved, and the method is particularly suitable for application scenes for storing massive images. And the data segmentation module can perform fault-tolerant coding operation on the compressed image data to obtain a plurality of segmented image data blocks, so that the disaster tolerance of file storage can be improved.
Referring to fig. 3, the present application provides an image processing system, which further includes, on the basis of the system shown in fig. 1 or fig. 2: and the backup module 16 is configured to backup at least two image data blocks according to a preset backup number, and send the at least two backed-up image data blocks to different file storage modules 14 respectively.
The backup module 16 may be disposed on a server, and is dedicated for backing up image data. Optionally, the backup module 16 may also be disposed on the same server as the data segmentation module 13, and configured to segment the image data and then backup each segmented image data block. The preset number of backups may be determined by backup module 16 in advance according to actual application requirements.
In this embodiment, when the client 10 obtains an image file, the image file may be uploaded to the file receiving module 11, the file receiving module 11 decomposes the image file to obtain meta information and image data, then sends the meta information to the meta data module 12, and sends the image data to the data dividing module 13, so that the data dividing module 13 divides the image data to obtain a plurality of image data blocks, and performs encoding operation on all the image data blocks to obtain a plurality of divided image data blocks. Then, the data segmentation module 13 sends the plurality of image data blocks to the backup module 16, so that the backup module 16 can backup each image data block according to a preset backup number of the split image data blocks, and then send each backed-up image data block to the plurality of file storage modules 14 for storage, thereby completing efficient storage of the image data. The processing system improves the safety of image data storage through a backup mode, and avoids the problem that the client cannot normally read the image file due to the fact that part of the image data is lost due to inevitable factors.
The processing system for images described in the embodiments of fig. 1 to fig. 3 realizes efficient storage of image files, and based on the processing system, the present application also provides a processing system capable of realizing efficient reading of images of image files, and the following embodiments will describe the processing system.

It should be noted that, if the meta information acquired by the file acquiring module 17 from the meta data module 12 is encrypted meta information, before the later-stage integrating unit 173 integrates the combined image data and the meta information, the file acquiring module 17 needs to decrypt the encrypted meta information, so that the later-stage integrating unit 173 integrates the combined image data and the decrypted meta information to completely read the target image file.
Optionally, referring to fig. 5, the present application further provides an image processing system, where on the basis of the system shown in fig. 4, the file obtaining module 17 may be further configured to receive a modification request of the target image file, obtain meta information of the target image file from the meta data module 12 according to the modification request, obtain image data of the target image file from each file storage module 14 according to the meta information of the target image file, obtain the target image file according to the meta information of the target image file and the image data of the target image file, and modify the target image file according to the modification request.
Optionally, the file obtaining module 17 may further include: a modifying unit 175 for modifying the target image file according to the modification request.
The target image file is an image file to be modified, and specifically, when the target image file is modified, meta information of the target image file can be modified or image data of the target image file can be replaced.
In this embodiment, the client 10 initiates a modification request of a target image file to be checked to the file obtaining module 17, after receiving the modification request, the obtaining unit 171 in the file obtaining module 17 may further analyze the modification request, obtain an identifier of meta information of the target image file, obtain meta information corresponding to the identifier of the meta information from the meta data module 12 according to the identifier of the meta information, determine a storage address and an identifier of the target image file according to an association relationship between the previously stored meta information and address information of each file storage module and an identifier of each image data block, correspondingly read an image data block corresponding to the identifier of each image data block from each file storage module 14 based on the address information of each file storage module 14, and then send each read image data block to the merging unit 172, so that the merging unit 172 merges all the image data blocks to obtain merged image data, i.e., the entire image data, the merging unit 172 sends the merged image data to the integrating unit 173, and the obtaining unit 171 sends the metadata of the previously determined target image file to the integrating unit 173, so that the integrating unit 173 integrates the merged image data and the metadata of the target image file, and the integrated image file is the target image file. Then, the integrating unit 713 sends the integrated target image file to the modifying unit 175, and the modifying unit 175 modifies the target image file according to the modification content included in the modification request, for example, modifies the meta information of the target image file (for example, the age of the patient, the examination time, etc.), and may also update the image data of the originally stored target image file.

It is understood that, when decompressing the merged image data, the decompressing unit 174 may specifically use a preset decompressing algorithm to parse the merged image data, and the decompressing algorithm used is matched with the compression algorithm used when compressing the image data.
The medical image processing system provided by the embodiment realizes efficient reading of the image file, and as long as the client initiates a reading request or a modification request to the file acquisition module, the file acquisition module can quickly decrypt the previously split meta information, integrate the image data acquired from the file storage module, and then directly return the image data to the client. Because the meta-information occupies a small amount of data, the meta-information can be quickly decrypted, and the efficiency of reading or modifying the target image file by the client is greatly improved.
In an application environment, after the merging unit 172 in the file obtaining module 17 merges the image data blocks to obtain merged image data, the merging unit 172 may further obtain the meta information of the target image file from the obtaining unit 171, and send the meta information of the target image file and the image data to the client 10 simultaneously or sequentially, so that the client 10 may display the target image file on the display screen. Specifically, since the amount of the meta-information is small, the client 10 may display the meta-information first, so that the user of the client 10 knows the related information first, and after the image data is received, the received image data may be further interpreted according to the meta-information.
In another application environment, after the integration unit 173 in the file acquiring module 17 integrates the meta information and the merged image data to obtain the target image file, the target image file may be sent to the client 10 for the user to view.
