Multiprotocol medical imaging communication through the Internet is more flexible than the tight DICOM transfers. This paper\r\nintroduces a modular multiprotocol teleradiology architecture that integrates DICOM and common Internet services (based on\r\nweb, FTP, and E-mail) into a unique operational domain. The extendedWADO service (a web extension of DICOM) and the other\r\nproposed services allow access to all levels of the DICOM information hierarchy as opposed to solely Object level. A lightweight\r\nclient site is considered adequate, because the server site of the architecture provides clients with service interfaces through the\r\nweb as well as invulnerable space for temporary storage, called as User Domains, so that users fulfill their applications� tasks. The\r\nproposed teleradiology architecture is pilot implemented using mainly Java-based technologies and is evaluated by engineers in\r\ncollaboration with doctors. The new architecture ensures flexibility in access, user mobility, and enhanced data security.
