Intellectual system architecture for medical data storage and processing

In present time synergy of bio-medical engineering and information technology becomes widely spread, because actual problem exists in the field of ophthalmology medical results processing and storage. Computer information system for complex human organism express-analysis with camera based on gas discharge visualization (GDV camera) usage was developed by Kirlionics Technologies International company (Russia, St. Petersburg). As the result of several Spain universities’ collaborative work information system SIRIUS was created (System for the Integration of Retinal Images Understanding Services), which represents web application based computer system for human visual analyzer retina images processing. Several universities’ collaborative work lead to development of SIRIUS information system (System for the Integration of Retinal Images Understanding Services), which represents web application based computer system for human visual analyzer retina images analysis. Software named VAMPIRE (Vascular Assessment and Measurement Platform for Images of the REtina) developed by Dundee University, allows performing semi-automatic estimation of human visual analyzer retina vessels and their geometry characteristics.

Authors’ suggestion for the purpose of solving ophthalmology medical results processing and storage problem is to utilize predictive non-invasive human visual analyzer diagnosis intellectual system (IS). Intellectual system is based on three-tier architecture.

First tier – client web application offering user interface and consisting of three subsystems.

Second tier – server containing IS logic and consisting of five subsystems.

Third tier – information repository represented with database (DB) and consisting of two subsystems.

In its own turn intellectual system tiers consist of following subsystems:

- First tier:

o subsystem that acquires input data from information sensors (ophthalmoscope and GDV camera);

o subsystem that converts input data into format supported by IS server;

o subsystem that transmits converted data to IS for the purpose of further processing.

- Second tier:

o authentication subsystem;

o authorization subsystem;

o subsystem that routes user query inside IS;

o subsystem that processes user query in destination module;

o response generation subsystem.

- Third tier:

o subsystem that controls inserted to the database data correctness and integrity;

o information backup subsystem.

First tier main function – information sensors’ connection with second tier implementation. Multimedia information acquiring is the result of browser-to-sensors interaction. Multimedia information acquired from GDV camera or ophthalmoscope is saved within ophthalmologist’s intellectual workplace operation system file structure.

Second tier function – query and data received from user interface processing, needed information search and retrieval according to the query in the format accepted for visualization by user interface.

Third tier function – data permanent storage provisioning and their loss prevention in the case of failures (software or hardware).

Authors suggested intellectual system architecture that allows noticeable medical information search, access, storage simplifying, accelerate data gathering process for diagnosis purposes and rehabilitation process complex accompaniment with individual approach application. Computer analysis methods and techniques application for human visual analyzer predictive diagnosis results permit to increase efficiency of therapeutic and rehabilitation activities.
