Description
Technical field
The present invention relates to Medical Image Processing, three-dimensional visualization and communication technical field, mainly be applicable to processing and the display packing of portable terminal to view data in the PACS system.
Background technology
Medical image files and communication system (Picture Archiving and Communication System, PACS) be information system important in the hospital, managing computer assisted tomography projection (Computed Tomography, CT), magnetic resonance imaging (Magnetic Resonance Imaging, MRI), the medical image of the generation such as ultrasonic (Ultrasonic, US) plurality of devices.By means of the PACS system, the doctor can in time view the full resolution medical image on computers.So not only improve doctor's diagnostic skill and diagnosis efficiency, and changed doctor's working method.In traditional system, the doctor can only at hospital internal, check patient's image and patient information by means of work station in the fixed position by local area network (LAN).But in the situations such as urgent rescue, remote diagnosis, the medical practitioner of hospital outside can not in time obtain patient's image and information, and this has lengthened Diagnostic Time greatly, has reduced diagnosis efficiency, is unfavorable in time patient being diagnosed.
And in the diagnosis of common burst disease (such as acute ischemic stroke, coronary heart disease), it is particularly important that the shape of blood vessel, position and depth information seem, and original two-dimensional medical images is difficult to accurately reflect above-mentioned information, need to by means of three-dimensional visualization technique, blood vessel be carried out three-dimensional visualization rebuild.Present diagnostic three-dimensional visualization method comprises: MIP (Maximum Intensity Projection, MIP), minimum density projection (Minmum Intensity Projection, MinIP), multiplanar reconstruction (MultiPlanar Reconstruction, MPR) and direct volume drawing (Direct Volume Rendering).MIP and MinIP can reflect the monochrome information of object, and the diagnosis of calcification and thrombus is had important effect.MPR can obtain according to original image the image of other cross section equal qualities.Direct volume drawing then can obtain high-quality rendering image, can represent intuitively the shape of each organ, and position, brightness and depth information are widely used in the medical diagnosis.
Because computing capability, storage capacity and the flying power of present mobile device are limited, on size of data, picture quality, interactive speed and visualized algorithm are selected, the medical image collection are carried out three-dimensional visualization and also have restriction.At present, the mobile hand-held device that generally uses lacks the support for three-D grain among the Open GL ES, therefore can only adopt the 2 d texture mapping algorithm to realize direct volume drawing, this algorithm need to make up three axial 2 d texture sequences in internal memory, this means and to finish the visual of same target at mobile device, need to take the internal memory that is equivalent to three times of three-D grains.In addition, the visual image that is generated by the 2 d texture mapping algorithm is relevant with direction of visual lines.When direction of visual lines and direction of principal axis are in 45 when spending, effect of visualization is relatively poor.The remote rendering technology not only can solve the restriction of memory size, also can be applicable to existing visualization technique and obtains high-quality image.And along with the application of many rows CT and high-resolution MRI, the increase of medical image sequences data volume, and it is complicated to carry out the algorithm of three-dimensional reconstruction, needs to carry out high-precision vector sum integral operation and realizes.The hardware condition of mobile hand-held device all is difficult to satisfy the real-time operation to 3-D view.

7. as claimed in claim 6 with processing and the display packing of portable terminal to view data in the PACS system, it is characterized in that, described portable terminal sends to intermediate server according to the information of awaiting orders that receives and plays up parameter, the intermediate server basis is played up parameter generating three-dimensional image, and sends to portable terminal; Portable terminal receives 3 d image data and shows and comprises:
Described portable terminal sends to described intermediate server according to the described information of awaiting orders that receives and plays up resolution and the picture quality factor;
Intermediate server is according to the described resolution generating three-dimensional image of playing up that receives;
Intermediate server compresses according to the 3-D view of the described generation of described picture quality factor pair that receives again, and the 3-D view after will compressing sends to portable terminal;
Portable terminal receives the 3 d image data that intermediate server sends, and carries out the decompress(ion) demonstration of contracing.
8. as claimed in claim 7 with processing and the display packing of portable terminal to view data in the PACS system, it is characterized in that, receive the 3 d image data that intermediate server sends at described portable terminal, carrying out decompress(ion) contracts when showing, record current network state information, and according to described network state information the described parameter of playing up is carried out the self adaptation adjusting; Concrete grammar comprises:
Described portable terminal elder generation target setting frame rate is played up the excursion of resolution, and the excursion of the picture quality factor is played up parameter update time and record timing statistics scope;
Portable terminal in each record data length when receiving 3 d image data, collect time and current time;
Portable terminal records again rejects apart from the data of current time before the record timing statistics of described setting;
Calculate at record and collect total number of data in the timing statistics and collect the time, and calculate actual frame rate;
The target frame rate of the described actual frame rate that calculates and described setting is compared; If actual frame rate greater than target frame rate, then improves the value of playing up resolution and the picture quality factor; If actual frame rate less than target frame rate, then reduces the value of playing up resolution and the picture quality factor; If actual frame rate equals target frame rate, then keep playing up resolution and the picture quality factor is constant;
The parameter of playing up that portable terminal will generate sends to intermediate server.
9. as claimed in claim 8 with processing and the display packing of portable terminal to view data in the PACS system, it is characterized in that, after described intermediate server upgrades the database of intermediate server by the original DICOM view data that receives, described original DICOM view data is carried out preliminary treatment.
10. as claimed in claim 9 with processing and the display packing of portable terminal to view data in the PACS system, it is characterized in that, receive the 3 d image data that intermediate server sends at described portable terminal, carry out decompress(ion) contract show after, the user operates the 3-D view on the described portable terminal;
If described operation relates to the remote rendering parameter, then portable terminal sends to described intermediate server with parameter, and intermediate server is rebuild the described volume data of Pixel Information that comprises, and will rebuild the image that obtains and send to portable terminal;
If operation does not relate to the remote rendering parameter, then mobile terminal self is handled it, and generates corresponding image and demonstration.
