Abstract

Telemedicine, which is the application of telecommunication tools for information processing in healthcare services, is one of the ways to increase its effectiveness. Remote consultations are an important part of telemedicine, but their implementation, in addition to using common communication tools, involves working with documents, including those in specific formats of diagnostic equipment. The article considers the possibility of implementing a compact module for accessing medical diagnostic data in the standard DICOM format in order to further integrate this converter as simply as possible into an information system for teleconsultations. For this purpose, a threetier architecture widely used in web technology was chosen, but with the implementation of the data layer based on special software that provides data import into formats acceptable for the web, i.e. DICOM data is converted into a standard JPEG image. This conversion takes into account the visualization parameters recorded in the examination file, or those transmitted in an asynchronous request from the client side of the system as the current settings from the user. In parallel with generating data for displaying the medical image in the browser, the data layer software prepares its textual supplement based on metadata from the DICOM file. At the same time, taking into account the configuration file that is set by system administration, the examination is anonymized by blocking part of the metadata, which is a mandatory component of the information security of the telemedical resource. Development testing has shown that the full data processing on the server side implemented in this project provides sufficient speed for user access to the image when changing the visualization parameters and scrolling through frames in series, which are the basis for structuring most graphical diagnostic files. Full data preparation and buffering on server side also simplifies the synchronization of graphical data playback on two or more clients, which is necessary for certain types of teleconsultations.
