Application of Multiprotocol Medical Imaging Communications and an Extended DICOM WADO Service in a Teleradiology Architecture

Abstract

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

The Virtual Reality Radiology Workstation: Current Technology and Future Applications

“…Importantly, cybersecurity has been incorporated into teleradiology practices since its inception, and there continues to be considerable research in this area seeking to improve and perfect security features. 43 Going forward, institutions must establish strict security measures to safeguard patient data if this technology is used for remote work.…”

A Web-Based Synchronized Architecture for Collaborative Dynamic Diagnosis and Therapy Planning

“…In addition, a multi-functional telemedicine system that supported both telediagnosis and teleconsultation services was proposed by Lin et al [31]. For the purpose of integrating DICOM and common Internet services into an operational domain that allowed access to all levels of the DICOM information hierarchy, Koutelakis et al [32] implemented a modular multiprotocol teleradiology architecture, while Mitchell et al [33] introduced a client-server teleradiology system for the diagnosis of acute stroke, which could interactively visualize 2D and 3D brain images on a smartphone device.…”

Teleradiology: current perspectives

“…27 Digital Imaging and Communications in Medicine (DICOM) also addresses security and privacy issues, and there is continued research into improving the standard and optimizing its performance. 28 For teleradiology, digital watermarking is becoming one of the more popular methods to protect images. Digital watermarking is a method of adding information to an image as a watermark (much like the watermark on a piece of paper or fifty dollar bill).…”
