A Web-based teleradiology system, called MITIS, is presented for the management and processing of obstetrical, gynecological, and radiological medical data. The system records all the necessary medical information in terms of patient data, examinations, and operations and provides the user-expert with advanced image-processing tools for the manipulation, processing, and storage of ultrasonic and mammographic images. The system can be installed in a hospital’s local area-network, where it can access picture archiving and communication system servers (if available), or any other server within the radiology department, for image archiving and retrieval, based on the DICOM 3.0 protocol over transmission control protocol/Internet protocol, and also it is accessible to external physicians via the hospital’s Internet connection. The teleradiology system is composed as a set of independent Web modules and a Win32 application for mammographic image processing and evaluation.
