Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, shall fall within the scope of the present invention.
As shown in fig. 1, which is a flowchart illustrating a method for compressing browser snippets according to an embodiment of the present invention, the method shown in fig. 1 is executed in a memory, and the method includes the following steps:
101. receiving a medical digital imaging and communication DICOM source file, and acquiring corresponding text data and image data according to the DICOM source file, wherein the DICOM source file is browser film reading data;
it should be noted that Digital Imaging and Communications in Medicine (DICOM) is an international standard for medical images and related information (ISO 12052), and among tens of thousands of medical Imaging devices in use, DICOM is one of the most widely deployed medical information standards, defining a medical image format that can be used for data exchange with quality meeting clinical needs.
Medical images of all patients are stored in a DICOM file format, which contains Protected Health Information (PHI) about the patients, such as name, gender, age, and other image-related information, such as device information for capturing and generating images and some context-related information for medical treatment. The medical image facility generates a DICOM source file that the physician reads and diagnoses problems found in the image using a DICOM reader (computer software capable of displaying DICOM images).
It is understood that the act of a doctor using a DICOM reader (computer software capable of displaying DICOM images) to read and diagnose a problem found in an image is a browser reading act, and the image being diagnosed, i.e. the DICOM source file, is browser reading data.
It is understood that the browser reading action may further include the patient viewing the diagnosis result of the patient, including text and images, by using other intelligent devices, for example, through a personal computer, a mobile phone, etc., and may also include viewing the images during the image sharing diagnosis of the cross-regional medical consultation.
102. Extracting compressed data according to the DICOM source file, the text data and the image data to obtain a target file;
it should be noted that the compressed data refers to specific data related to the explicit diagnosis result in the text and image information in the dicom source file, for example, device information for capturing and generating an image contained in the dicom source file is information unrelated to the diagnosis result, and therefore, the compressed data needs to be further extracted from the text and image information in the dicom source file, so as to further reduce the compression range of the target file.
103. And compressing the target file by using a preset compression algorithm to obtain a target compressed file.
In the embodiment of the present invention, compressing the target file with the reduced compression range may further reduce the occupied space of the obtained target compressed file.
It will be appreciated that the pre-set compression algorithm may be a compression algorithm implemented based on LZ77 encoding theory.
According to the embodiment of the invention, a DICOM source file is received, and corresponding text data and image data are acquired according to the DICOM source file, wherein the DICOM source file is browser reading data; extracting compressed data according to the DICOM source file, the text data and the image data to obtain a target file; and compressing the target file by using a preset compression algorithm to obtain a target compressed file. By extracting compressed data from the DICOM source file, the text data and the image data, the compressed data is simplified relative to the original file, and the target file is compressed by using a compression algorithm, so that the storage length required by storing the compressed target file can be further reduced, the occupation of the disk space is reduced, and the enterprise cost is reduced.
To better understand the embodiment of the present invention, as shown in fig. 2, another schematic flow chart of a method for compressing browser browsing data according to the embodiment of the present invention is shown, where the method shown in fig. 2 specifically includes the following steps:
201. receiving a medical digital imaging and communication DICOM source file, and acquiring corresponding text data and image data according to the DICOM source file, wherein the DICOM source file is browser film reading data;
the content related to step 201 included in the compression method for browser rendering data in the embodiment of the present invention shown in fig. 2 is similar to the content related to step 101 in the compression method for browser rendering data in the embodiment shown in fig. 1, and specifically, the content described in step 101 in fig. 1 may be referred to, and is not described herein again.
In an embodiment of the present invention, receiving a DICOM source file for digital imaging and communications in medicine further comprises:
sending a source file acquisition request to an imaging device;
if the source file acquisition response is received, extracting the DICOM source file from the source file acquisition response;
and if the source file delay response is received, receiving the DICOM source file fed back by the imaging equipment after waiting for a preset delay time.
In the embodiment of the present invention, medical images of any one imaging device, such as Computed Tomography (CT), Angiography (Angiography), Nuclear Magnetic Resonance Imaging (NMRI), and the like, may be acquired according to the DICOM standard.
It can be understood that, when a doctor wants to diagnose a dicom source file in any imaging device, the doctor wants to send an acquisition request to the imaging device through a client for acquiring images;
it can be understood that, if the imaging device has finished shooting the image, i.e., the dicom source file, when receiving the acquisition request sent by the image acquisition client, the imaging device sends an acquisition response, and the image acquisition client extracts the dicom source file from the acquisition response; if the imaging device does not finish shooting the image, namely the dicom source file, when receiving the acquisition request sent by the image acquisition client, the imaging device sends out a delay response including a preset delay time, so that the image acquisition client receives the dicom source file fed back by the imaging device after waiting for the preset delay time.
In the embodiment of the present invention, the acquiring corresponding text data and image data according to a DICOM source file includes:
intercepting images from a DICOM source file according to frames to obtain a plurality of images with corresponding frame numbers, and virtually printing the plurality of images in a preset typesetting format through a virtual printer to obtain a typesetting image containing the plurality of images;
and performing preset format conversion on the typeset image to obtain corresponding text data and image data in a preset format file.
It can be understood that the DICOM source file is a medical image which is shot by a patient through any imaging device according to the DICOM standard, and after the DICOM source file is received, the image needs to be intercepted for the convenience of the doctor or the patient to view.
It should be noted that the DICOM standard covers almost all information exchange protocols of acquisition, archiving, communication, display, query and the like of medical digital images, so that diagnostic images are intercepted from images according to frames through the DICOM acquisition standard, and because the diagnosis of a patient needs to view an affected part in all directions to obtain an accurate diagnosis result, the image needing to be intercepted is not only one frame, and after a plurality of diagnostic images are obtained, the plurality of images are typeset in a preset typesetting format through a DICOM virtual printer and then are subjected to virtual printing to obtain the DICOM images.
It can be understood that, based on the specific image format, firstly, the image is caused to contain a large amount of text and image information, and secondly, the reader used in the viewing is also specific, so that when the image is viewed or transmitted, not only much disk space and operating memory are occupied, but also a reader supporting the format needs to be installed, and in order to make the image more convenient to view, the file format needs to be converted into a common format.
The method for converting the preset format of the typeset image to obtain the corresponding text data and image data in the preset format file comprises the following steps:
converting the typesetting image into an XML format file to obtain text data in the XML format file;
and (4) the typeset images are packaged into portable network picture png format files and destructive image jpeg format files, and image data in the png format files and the jpeg format files are obtained.
In the embodiment of the present invention, the xml format file is a file obtained by reading the non-image data portion in the layout image.
In the embodiment of the present invention, the portable network picture png format file is a file obtained by reading the image data portion in the layout image.
In the embodiment of the present invention, the destructive image jpeg format file is a file obtained by reading the image data portion in the layout image and performing down-sampling.
It is understood that the compression algorithm compresses data corresponding to text or images, and thus extracts desired text data and image data from the above-described format.
The reason for extracting the data after the DICOM image is converted into the preset format is two: first, to save time; secondly, in order to obtain an image which is easy to view when decompressing.
It should be noted that, data can be directly extracted from a DICOM image, but due to the special format, conversion of many algorithms is required, so that the extraction process cannot be performed quickly and stably, a lot of time is wasted, and the extraction efficiency is reduced.
In the embodiment of the invention, the DICOM image is converted into the xml format file, the png format file and the jpeg format file, and then the data is extracted, so that the compressed file can obtain the file format which is convenient to view after being decompressed without being converted again.
202. Analyzing DICOM source files, text data and image data by using a preset protocol to obtain compressed data;
203. performing data merging storage on the compressed data in a byte array mode to obtain a target file;
in the embodiment of the present invention, the preset protocol may be a dicom3.0 protocol or any other protocol that can be resolved. And further analyzing the DICOM source file, the text data and the image data through a preset protocol, extracting all data to be compressed as compressed data, and merging and storing the compressed data in a byte array form to obtain a target file.
204. And compressing the target file by using a preset compression algorithm to obtain a target compressed file.
The content related to step 204 included in the compression method for browser rendering data in the embodiment of the present invention shown in fig. 2 is similar to the content related to step 103 in the compression method for browser rendering data in the embodiment shown in fig. 1, and specifically, the content described in step 103 in fig. 1 may be referred to, which is not described herein again.
In the embodiment of the present invention, compressing the target file by using a preset compression algorithm to obtain the target compressed file, and then further includes:
if a storage request is received, storing the target compressed file to a disk;
and if the transmission request is received, the target compressed file is stored to a disk and then transmitted to the request sending client.
In the embodiment of the invention, after the target file is compressed in the memory to obtain the target compressed file, the target compressed file needs to be stored in the disk, and when other clients, namely the patient end or other doctor seeing ends send transmission requests, the stored target compressed file is transmitted to the corresponding client.
The method comprises the steps of receiving a medical digital imaging and communication DICOM source file, and acquiring corresponding text data and image data according to the DICOM source file, wherein the DICOM source file is browser film reading data; using a preset protocol to analyze a DICOM source file, text data and image data to obtain compressed data; performing data merging storage on the compressed data in a byte array mode to obtain a target file; and compressing the target file by using a preset compression algorithm to obtain a target compressed file. The target files obtained by merging the compressed data in a byte array mode are compressed, so that the compression range is further reduced, the obtained target compressed files are stored to a disk, the occupied space is less, the enterprise cost is reduced, and the transmission speed is higher when the target compressed files are transmitted to other clients for reference.
To better understand the embodiment of the present invention, as shown in fig. 3, a further flowchart of a method for compressing browser browsing data according to the embodiment of the present invention is shown, where the method shown in fig. 3 specifically includes the following steps:
301. receiving a medical digital imaging and communication DICOM source file, and acquiring corresponding text data and image data according to the DICOM source file, wherein the DICOM source file is browser film reading data;
302. analyzing DICOM source files, text data and image data by using a preset protocol to obtain compressed data;
303. performing data merging storage on the compressed data in a byte array mode to obtain a target file;
the contents related to steps 301, 302, and 303 included in the compression method for browser rendering data according to the embodiment of the present invention shown in fig. 3 are similar to the contents of steps 101, 201, 202, and 203 in the compression method for browser rendering data according to the embodiment shown in fig. 1 and fig. 2, and specifically refer to the contents described in steps 101, 201, 202, and 203 in fig. 1 and fig. 2, which are not repeated herein.
304. Calculating the length of memory bytes occupied by the target file to obtain the length of bytes to be compressed;
it is understood that, before compressing the target file, the length of the bytes to be compressed of the target compressed file needs to be determined, and other calculation methods may be performed by using a function in C language, a function in JAVA, and the like, which is not limited in this example.
Taking the calculation by using the function in the C language as an example, further details are given as follows:
(1) calling an ifstream function to open a file to be calculated;
(2) calling a seekg function to set the get pointer as the end of the file, seekg (0, ios _ base:: end);
(3) calling a tellg function to obtain the total byte number, wherein the actually obtained offset byte number of the get pointer relative to the file header;
(4) reset get pointer to point to the header so as to execute other operations seekg (0, ios:: beg);
for each read of a file by the ifstream, the ifstream can be called, wherein gcount obtains the number of bytes read, the return value of gcount is streamsize, and streamsize is integer, signed int or signed long.
It is to be understood that the above examples are illustrative only and not limiting in any way
305. And determining a compression parameter of a preset compression algorithm according to the length of the byte to be compressed, and compressing the target file by using the compression parameter to obtain the target compressed file.
It can be understood that LZ77 encoding is a dictionary-based lossless compression algorithm, widely used in communication, computer file archiving, etc., and encodes long character strings (also called phrases) into short labels, and replaces the phrases in the dictionary with small labels, thereby achieving the purpose of compression. That is, it compresses data by replacing a long string of multiple repeated occurrences in the data with small marks. The symbols to be processed are not necessarily text characters, and may be symbols of any size. Different dictionary-based algorithms use different methods to maintain their dictionaries, LZ77 using a forward buffer and a sliding window.
Where LZ77 first loads a portion of the data into the forward buffer, in order to facilitate understanding how the forward buffer stores phrases and forms a dictionary:
first, we depict the buffer as a character sequence of S1, …, Sn, and Pb is a set of phrases consisting of characters, n phrases being composed from the character sequence S1, …, Sn, defined as follows:
pb { (S1), (S1, S2), …, (S1, …, Sn) }, e.g., if the forward buffer contains a character (a, B, D), then the phrase in the buffer is { (a), (a, B, D) };
second, once a phrase in the data passes through the forward buffer, it will move into the sliding window and become part of the dictionary. To better understand how phrases are represented in a sliding window, first, imagine the sliding window as a sequence of characters of S1, …, Sm, and Pw is a phrase set composed of these characters, the process of generating a phrase data set from the sequences S1, …, Sm is as follows:
pw { (Si), (Si, Si +1), …, (Si, Si +1, …, Sm) }, for example, if the symbol (a, B, C) is included in the sliding window, then the phrases in the window and the dictionary are { (a), (a, B, C), (B, C), (C) };
it will be appreciated that the main idea of the LZ77 algorithm is to continually find the longest phrase in the forward buffer that can be matched to the phrase in the dictionary. Taking the forward buffer and sliding window described above as examples, the longest matching phrase is (a, B).
There are two cases of matching between the forward buffer and the sliding window: either a matching phrase is found or no matching phrase is found. When the longest match is found, it is encoded as a phrase marker.
Wherein the phrase token contains three parts: 1. offset in sliding window: the previous character from the head to the start of the match; 2. the number of symbols in the matching; 3. after the matching is over, the first symbol in the forward buffer.
It will be appreciated that when no match is found, the unmatched symbol is encoded into a symbol tag. This symbol mark contains only the symbol itself and no compression process. In fact, we will see that the symbol mark is actually one bit more than the symbol, so slight spreading occurs.
It will be appreciated that once the n symbols have been encoded and the corresponding markers generated, the n symbols are removed from one end of the sliding window and replaced with the same number of symbols in the forward buffer. The forward buffer is then refilled. This process keeps the most recent phrase in the sliding window. The number of phrases specifically maintained by the sliding window and the forward buffer is determined by their own capacity.
In the embodiment of the present invention, a preset algorithm is an LZ77 algorithm, and an LZ77 algorithm is used to compress a character string abacbababcacad as an example, and a compression process is described as follows:
firstly, determining a compression parameter according to the byte length of a character string to be compressed, wherein the size of a sliding window is 8 bytes, and the size of a forward buffer is 4 bytes.
Next, the compression of the string ababcabacad is started:
starting: finding no matching phrase from the forward buffer ABAB in the sliding window, encoding a as the symbolic marker a;
finding no matching phrase from a forward buffer BABC in a sliding window A, and coding B into a symbol mark B;
finding phrase AB in sliding window AB from forward buffer ABCB, at the position of sliding window offset 6, coding AB into symbol mark (6, 2, C);
finding the phrase BAB from the forward buffer BABA in the sliding window ABABC at the position of the sliding window offset of 4, and coding the BAB into a symbol mark (4, 3, A);
finding phrase BC at the position with the sliding window offset of 2 in a forward buffer area BCAD in a sliding window BABCBABA, and marking BC code as (2, 2, A);
sixthly, encoding D as a symbol mark D in the sliding window CBABABCA from the forward buffer D, wherein D is not found in the sliding window.
