NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
An Innovatively Collaborative and Extensible Mobile Consultation and Diagnosis Platform with Advanced Data Transmission
Background:
Mobile consultation and diagnosis platform (MCDP) gets rid of limitations in fixed location for radiologists, which has improved the efficiency of diagnosis. Experts who located in different places could discuss cases on-line with visualization of medical images. In recent years, a great number of papers have published different related platforms. Due to unacceptable performance in Internet or incomplete functional designs, most of them cannot carry out in practice.
Objective:
The objective of our study was to build and test a novel MCDP with enough features and transmission method for practices in clinics.
Methods:
For these problems, an advanced collaborative strategy was proposed. During group discussion, privileged user (everyone could be) has right to interact images accompanied by AV in mobiles. Screen is shared for clients as if they located in a face to face conference. Another innovation involved optimization of traditional difference transmission. Compared with description of two integers, we put forward the bit difference compression transmission that endows bit new content and saves attractive scale of data. This idea has been applied in neighbor images delivery for sharing successfully. However, it becomes frustrated within remote 3D volume due to low similarity. We presented a novel remote collaboration in 3D volume rendering by camera status sharing, which can survive in bad network condition. By experiments it proved that proposed algorithms have obvious predominance rather than popular methods. Moreover, CUDA and off-screen techniques came to resolve speed and rendering windows overlapped. At last, we gave an excited feature plug-in. Clients can develop and share specialized plug-ins embedded in server, enriching platform for certain areas.
Results:
In evaluation of functional implementation, we had compared our proposed MCDP with similar 18 ones cited highly in recent years. As we presented advanced collaborative or transmission ideas in 2D and 3D synchronization, our platform had obvious advantages. In 11 evaluative standards, it is difficulty for a MCDP accounts for more than 60%, but ours satisfies 100%. In performances of 2D transmission, scale of necessary data by bit difference compression transmission is near 50% of difference transmission, 40% of blocks and 55% of H.264. Meanwhile, in evaluation of advanced 3D collaborative method, our proposed solution acquires extremely no more than 0.1 KB with 10 fps, when other methods cannot be accepted at all.
Conclusions:
Compared with other familiar platforms our proposed MCDP has innovative features for promoting feasibility in practice. Future work is to increase parallel computing ability and facilitate plug-in market for clients. Moreover, we wish to improve interactive experience in web for widespread.
