As shown in Figure 1, the present embodiment provides multiple stage mobile terminal and terminal medical grade image data transmission method comprise the steps:
Step S101, first terminal and the 2nd terminal set up data cube computation, and mode of connection is that direct WiFi/ bluetooth connects, or network connects;
Step S102, select one or more medical imaging picture to be sent;
Step S103, sending after instruction when receiving, described first terminal will be sent to described 2nd terminal after described medical imaging image ciphering;
The view data received is decrypted by step S104, described 2nd terminal, and reduction obtains original medical imaging picture.
In the present embodiment, described first terminal is the terminating unit of patient, described 2nd terminal is doctor or relatives or other people terminating unit, and terminating unit can be mobile terminal (such as smart mobile phone, panel computer etc.), fixed terminal (such as computer etc.) here. First terminal and the 2nd terminal set up data cube computation, if two terminals are in close together, between two mobile phones, can directly connect by opening WiFi module or bluetooth module, if the 2nd terminal is computer, when computer is inserted with wireless WiFi network interface card, it is also possible to directly connect. If two terminals cannot directly connect, can also being connected by internet like this, such as in hospital, patient's mobile phone connects hospital lan, the working computer of doctor also accesses hospital lan simultaneously, and medical imaging picture can be sent to the working computer of doctor by patient. And for example, patient's mobile phone connecting Internet, is sent to the computer of family relatives by medical imaging picture. Achieve medical imaging picture and it is sent to the 2nd terminal from first terminal.
Hospital for patient check time, can medical imaging picture be saved in background server, patient can download to this locality by first terminal. For each image check, generating a folder, folder includes the picture number of relevant inspection, generation time of medical imaging picture, hospital department information etc. simultaneously. When medical imaging picture is sent to the 2nd terminal by needs of patients, whole folder can be selected as required on first terminal, folder can also be entered and select suitable medical imaging picture, then click and confirm to send button, after receiving transmission instruction, described first terminal will be sent to described 2nd terminal after described medical imaging image ciphering.Due to the medical imaging picture of the patient of transmission, it is contemplated that to the confidentiality of data, it is necessary to be encrypted by picture, avoid picture to leak, reveal conditions of patients. Certainly, in the 2nd terminal, corresponding client terminal is installed, can decipher according to default deciphering algorithm and obtain original medical imaging picture.
As a kind of implementation of described encryption method, as shown in Figure 2, comprise the steps:
Step S201, for often opening medical imaging picture, picture generates arbitrary trajectory, the curve of any amount and/or straight line, picture is divided into some fritters.
Picture, by picture is carried out piecemeal numbering, is then spliced by present embodiment in the 2nd terminal, and reduction obtains original medical imaging picture. Fig. 3 is the schematic diagram of picture piecemeal, by some curves and/or straight line, picture is divided into some fritters. Every bar line is all walk line according to pixel.
There is a line segment between step S202, any two adjacent isles, by all line segments pixel random assignment eigenwert of process, if picture exists border pixel in fritter, then record this border pixel.
After the wired mutual intersection of institute, many line segments can be obtained, the public line segment that every bar line segment is between two adjacent isles. This step by all line segments pixel random assignment eigenwert of process, such as at random for each pixel distributes a bit position 0 or 1 as eigenwert. If fritter is border fritter, namely fritter is positioned at the position, border of picture, there is one section of border pixel, then records this border pixel, and such as can record horizontal boundary is 01, and record vertical edges circle is 10.
Step S203, from picture select a fritter as initial piece, its adjacent fritter is carried out serial number, according to numbering order traversal numbering fritter from small to large, for each numbering fritter continue the unnumbered fritter that it is adjacent is carried out serial number, until all fritters numbering is complete, preserve the mapping table that fritter is adjacent fritter simultaneously.
After picture piecemeal completes, in addition it is also necessary to fritter is numbered. select any fritter as initial piece from picture, it is labeled as 0, in adjacent isles, an optional fritter is labeled as 1, then according to the clock-wise order follow-up fritter of numbering that adds 1 every time, then for each numbering fritter continue the unnumbered fritter that it is adjacent is carried out serial number, until all fritters numbering complete. in general preferred picture four angles, the fritter at any one angle is as initial piece. in figure 3, select the fritter in the upper left corner as initial piece, it is labeled as 0, initial piece has 3 adjacent isles, 1 it is labeled as respectively according to clock-wise order, 2, 3, then the adjacent isles of fritter 1 is numbered, the fritter numbered is just without the need to again numbering, skip, therefore here only need to numbering fritter 5, then continue in order to fritter 2, 3, the adjacent isles of 4 is numbered, the adjacent isles of fritter 2 is labeled as 6, 7, the adjacent isles of fritter 3 is labeled as 8, 9, fritter 4 does not have unlabelled adjacent isles, so skip continuation the adjacent isles of fritter 5 to be numbered, according to this kind of rule, all fritters are numbered, after having numbered, the numbering of each fritter is as shown in Figure 3. the quantity splitting lines in actual can be more, and each fritter after therefore dividing is smaller, and quantity is considerably beyond 38.
After numbering completes, just obtain fritter mapping table. Mapping table corresponding to the segmentation fritter shown in Fig. 3 is as shown in Figure 4.
Step S204, all fritters being selected to be sent to described 2nd terminal at random, and described mapping table is also sent to described 2nd terminal, each fritter comprises fritter pixel, also comprises the eigenwert of boundary sections pixel and the offset sequence of pixel.
When sending fritter, send at random. Each fritter sent, not only comprises the pixel of whole fritter, also comprises the eigenwert of boundary sections pixel and the offset sequence of pixel. As shown in Figure 5, it is according to row head-end of line-end of line-row head-row head-end of line that fritter preserves in this locality ... order arrangement, assuming currently to be saved in one-row pixels first to end of line from row, end of line pixel is edge pixel, has eigenwert, therefore end of line pixel can be identified, then preserve the off-set value of pixel, i.e. the distance of descending end of line pixel and current every trade tail pixel, then continue from end of line to the first relieved preservation row pixel of row, preserving a pixel in this way successively, eigenwert is off-set value.
2nd terminal needs to carry out reverse deciphering operation after receiving the data, specifically as shown in Figure 6, comprises the steps:
Step S601, find initial piece and adjacent isles according to numbering first in the mapping table.
During deciphering, first read mapping table and find initial piece, be namely numbered the fritter of 0, and the fritter that initial piece adjacent, and can search in the fritter received according to numbering.
Step S602, for every bar edge line segment pixels of initial piece, in the adjacent isles of initial piece, find fritter belonging to edge line segment that eigenwert mates mutually, and by this fritter correspondence splicing initial piece of consecutive position.
Step S603, then continuation select next fritter, its corresponding fritter is found in the mapping table for current fritter, to the edge line segment pixels of current fritter remainder, find fritter belonging to edge line segment that eigenwert mates mutually, by the fritter correspondence splicing found in current fritter consecutive position.
Each fritter has some edge line segments (not comprising picture boundary), for the pixel of all edges line segment of fritter, the adjacent isles that there is same characteristic features value is found according to its eigenwert, the edge pixel that then two adjacent isles have same characteristic features value is spliced one by one, certainly owing to the pixel of stitching portion is repeated once, the pixel that edge line segment repeats therefore also is deleted.
Concrete, for initial piece 0, adjacent isles has 1,2,3 totally three fritters, first-selected read initial piece 0 on the right side of the eigenwert of pixel of an edge line segment, then in the eigenwert of the edge line segment pixels point reading these three fritters respectively, after finding identical edge line line segment, namely edge line segment feature value on the right side of the pixel eigenwert of fritter 1 left side edge line segment and initial piece 0 is identical, the right side that the left side edge line segment of fritter 1 is so just aligned to one by one initial piece 0 according to pixel, is so just spliced to the right side of initial piece 0 by fritter 1 entirety. Also to be deleted fritter 1 left side edge pixel simultaneously, avoid splicing rear pixel and repeat.
For each fritter, after reading first will by the data of this fritter as in buffer memory district, according to order restoring pixel shown in Fig. 5, after reading end of line pixel, encounter the eigenwert of end of line pixel and the off-set value of next pixel, the position of descending end of line pixel so can be found according to off-set value, then data are read forward until row is first, after reading eigenwert equally, change a line again, so just can pixels all in fritter be read in internal memory, complete the digital independent of a fritter, according to the pixel eigenwert that then can obtain fritter all edges line segment, carry out matched and searched.
After finding edges matched line segment, directly the whole block of pixels of this fritter in whole buffer memory district is clipped in splice region, the pixel data of the fritter that splice region has been spliced for storing, when shearing, also to be deleted eigenwert and the off-set value of edges matched line segment pixels point.
Step S604, when all fritters select splicing after, obtain original medical image picture.
After all fritters have spliced, so just obtain original medical image picture in splice region, then it is saved in the 2nd terminal local.
The foregoing is only the better embodiment of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. done within the spirit and principles in the present invention, all should be included within protection scope of the present invention.
