Therefore, if there are too many users downloading the medical image file at the same time, the bandwidth of the download server occupied by each user will be very small. Since medical image files are usually relatively large, the transmission is particularly slow, which will inevitably affect Download speed to all u

Example Embodiment
[0027] The present invention will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0028] The BitTorrent (BT) protocol is a file distribution protocol that uses Uniform / Universal Resource Locator (URL) to identify content and integrates seamlessly with the network. Its advantage on the HTTP platform is that downloaders who download a file at the same time continuously upload data to each other while downloading, so that the download server that provides the file source can support a large number of downloaders from the server and others at the same time when the load is limited. Client download, which can reduce the load of the service provider and save the cost of providing services. Because BT adopts a multi-target shared download method, the download speed of the client can be conti...

The invention provides a medical image file transmission system, a medical image file transmission method and a server based on a bit torrent protocol. The system comprises a central server, a tracking server and a client. The central server is used for packaging a medical image file into at least one data packet in units of series in digital imaging and communications in medicine (DICOM), making a seed file for each data packet and storing the data packets and the seed files, releasing identifiers generated by the bit torrent protocol for the data packets to the tracking server, receiving a request sent by the client and used for downloading the seed file of a specified data packet, and sending the seed file of the specified data packet to the client through a secure sockets layer (SSL) protocol, wherein one data packet corresponds to one series. The tracking server is used for storing the identifiers of the at least one data packet, storing information of the central server capable of providing the data packets and information of the client, and receiving a request sent by the client and used for acquiring information of the central server capable of providing the specified data packet and information of other clients. The client is used for issuing a request for downloading the seed file of the specified data packet to the central server, acquiring the seed file of the specified data packet from the central server through the secure sockets layer (SSL) protocol, issuing a request for acquiring information of the central server capable of providing the specified data packet and information of other clients to the tracking server according to the acquired seed file, and downloading data from the central server capable of providing the specified data packet and/or other clients according to the information acquired from the tracking server so as to acquire the specified data packet.
Description
Technical field [0001] The invention relates to the technical field of image transmission, in particular to a medical image transmission system and method based on the bitstream BitTorrent protocol, and a central server and method for publishing medical image files. Background technique [0002] In traditional medical information systems, the transmission of medical images is mainly implemented by HyperText Transfer Protocol (HTTP), File Transfer Protocol (FTP), etc. As far as the implementation of these protocols is concerned, generally the medical image files to be transmitted are first collected on the downloading server. When a user requests a download, the download server directly transmits the medical image file requested by the user to download apps. Therefore, if there are too many users downloading the medical image file at the same time, the bandwidth of the download server occupied by each user will be very small. Since medical image files are usually relatively large...
