Description
Technical field
The invention belongs to DCM technical fields, and in particular to a kind of data transfer and storage method based on DCM files.
Background technology
With the development and the continuous improvement of computer application level of information technology, medical information system of new generation has progressively developed into towards medical services, the synthesization multimedia management information system for hospitals of integrated medical information, medical image information and medical control information.For the ease of the shared of image information and exchange, ACR and American National appliance manufacturers association combine and have formulated medical digital images communication standard DICOM3.0, its main purpose is, in order to provide consistent interface between various medical imaging products, digitized video to be exchanged more effectively to be transmitted between medical imaging device.At present, main in the world Medical Devices manufacturer all uses this standard as the interworkng interface and medical image digital interface of medical imaging device.
But transmitted using the DCM files in existing DICOM3.0 sometimes mistake can occurs with data storage because of extraneous interference, so easily trigger to the erroneous judgement of medical data so as to cause the generation of malpractice.
The content of the invention
It is an object of the invention to provide a kind of data transfer and storage method based on DCM files, the dicom standard interface first in each self-configuring in some medical imaging devices for needing and being in communication with each other, so some medical imaging devices for needing to be in communication with each other can be just attached by respective dicom standard interface with communication network, so as to reach the purpose of transmission data mutually, in conjunction with other encrypting step methods, the invention can just be allowed to avoid the DCM files in existing DICOM3.0 can easily trigger the erroneous judgement to medical data so as to cause the problem of the generation of malpractice transmitting with data storage because extraneous interference causes to occur wrong.
It is specific as follows the invention provides a kind of data transfer based on DCM files and the processing scheme of storage method in order to overcome deficiency of the prior art：
A kind of data transfer and storage method based on DCM files, step are as follows：
Step 1：The dicom standard interface first in each self-configuring in some medical imaging devices for needing and being in communication with each other, so some medical imaging devices for needing to be in communication with each other can be just attached by respective dicom standard interface with communication network, so as to reach the purpose of transmission data mutually；
Step 2：So after these medical imaging devices collect image data, just these image datas according to data set mode end to end composition DCM files successively；
Step 3:After constituting DCM files, then it is packaged, this encapsulation belongs to the head addition encryption head in DCM files, and in the afterbody addition encryption tail of DCM files；
Step 4：After encapsulating DCM files, medical imaging device is just stored the DCM files after encapsulation in storage region；
Step 5：If necessary to be in communication with each other between medical imaging device, the DCM files after encapsulation are just read out from the storage region of medical imaging device, be then sent in other medical imaging devices by dicom standard interface and by communication network；
Step 6：Other medical imaging devices receive encapsulation after DCM files after, respectively by encrypt data carry out verification confirm data it is errorless after, then to encryption head decode, obtain encapsulation after DCM files in data.
Described data set includes some data elements being linked in sequence, and each data element is made up of the label, Value Types statement, value length and the data value body that are linked in sequence.
The encryption head of the DCM files after described encapsulation includes the file type of 1 byte being linked in sequence, patient information more than salt values, 8 bytes needed for the device type of 2 bytes, the encryption of 4 bytes, and the encryption tail of the DCM files after described encapsulation includes the CRC check code of 4 bytes.
The advantage of the invention is that can be achieved with verification and encryption function using encryption head and encryption tail, it is ensured that the stabilization of data transfer and accurate.
Brief description of the drawings
Fig. 1 is connection diagram of the invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples：
As shown in figure 1, data transfer and storage method based on DCM files, step is as follows：
Step 1：The dicom standard interface first in each self-configuring in some medical imaging devices for needing and being in communication with each other, so some medical imaging devices for needing to be in communication with each other can be just attached by respective dicom standard interface with communication network, so as to reach the purpose of transmission data mutually；
Step 2：So after these medical imaging devices collect image data, just these image datas according to data set mode end to end composition DCM files successively；
Step 3:After constituting DCM files, then it is packaged, this encapsulation belongs to the head addition encryption head in DCM files, and in the afterbody addition encryption tail of DCM files；
Step 4：After encapsulating DCM files, medical imaging device is just stored the DCM files after encapsulation in storage region；
Step 5：If necessary to be in communication with each other between medical imaging device, the DCM files after encapsulation are just read out from the storage region of medical imaging device, be then sent in other medical imaging devices by dicom standard interface and by communication network；
Step 6：Other medical imaging devices receive encapsulation after DCM files after, respectively by encrypt data carry out verification confirm data it is errorless after, then to encryption head decode, obtain encapsulation after DCM files in data.Described data set includes some data elements being linked in sequence, each data element is made up of the label, Value Types statement, value length and the data value body that are linked in sequence, wherein label is the signless integer pair of 16, and arrangement in order includes group number and element number；Described Value Types are expressed as the character string of 2 bytes, are the VR values of data element, and the VR of data-oriented element tags has specific definition in data dictionary, and the VR of this two byte is encoded with the default character collection of DICOM；Data value length is the signless integer of 16 or 32, indicates the length of accurate data value body, is recorded by byte number；Its length of data value body is even bytes, indicates the value of data element, and such DCM file structures are compact and reasonable, and space and efficiency high are saved in storage.The encryption head of the DCM files after described encapsulation includes the file type of 1 byte being linked in sequence, patient information more than salt values, 8 bytes needed for the device type of 2 bytes, the encryption of 4 bytes, so can be just encrypted with reference to salt values by encrypting head, and the encryption tail of the DCM files after described encapsulation includes the CRC check code of 4 bytes, the verification to DCM files is so can be achieved with reference to CRC check code.
The above, only it is presently preferred embodiments of the present invention, not make any formal limitation to the present invention, although the present invention is disclosed above with preferred embodiment, but it is not limited to the present invention, any those skilled in the art, without departing from the scope of the present invention, when making a little change using the technology contents of the disclosure above or be modified to the Equivalent embodiments of equivalent variations, in every case it is without departing from technical solution of the present invention content, according to technical spirit of the invention, within the spirit and principles in the present invention, any simple modification made to above example, equivalent and improvement etc., still fall within the protection domain of technical solution of the present invention.
