Quick access to radiological images is important for timely diagnosis and effective patient treatment. In this paper, we present a web-based client–server system seamless image volume rendering of DICOM that provides fast the data needed without placing heavy load on computer resources client side. are rendered server, resulting 2D sent physicians who can view analyze them via web browser. Secu...

PURPOSE Collecting and analyzing findings constitute the basis of medical activity. Computer assisted medical activity raises the problem of modelling findings. We propose a unified representation of findings integrating the representations of findings in the GAMUTS in Radiology [M.M. Reeder, B. Felson, GAMUTS in radiology Comprehensive lists of roentgen differential diagnosis, fourth ed., 2003...

PURPOSE To present the experience in patient dose management and the development of an online audit tool for digital radiography. MATERIALS AND METHODS Several tools have been developed to extract the information contained in the DICOM header of digital images, collect radiographic parameters, calculate patient entrance doses and other related parameters, and audit image quality. RESULTS Th...

PURPOSE Various technologies have been established for DICOM data exchange in radiology. In addition to the patient CD, online transfers via VPN (virtual private network) or DICOM email are common practice. However, dedicated network solutions are generally not appropriate for data exchange with occasional and spontaneous partners due to missing infrastructure at the partner institutions and/or...

The use of biomarkers derived from radiological images as surrogate end-points in therapeutic cancer clinical trials is well established. DICOM is the ubiquitous standard for the interchange of images for both clinical use as well as research. It also has capabilities for the exchange of image-related information, including categorical and quantitative information derived from images. The use o...

We present a concept for a medical video server extended by a DICOM interface. DICOM conform security mechanisms will be integrated to enable secure Internet access. Especially digital stereoscopic video sequences (DSVS) that are relevant for surgery should be examined regarding clip length necessary for diagnosis and documentation and clip size manageable with today’s hardware. Methods for DSV...

Medical image data generally need a huge amount of resources for storage and transmission. In recent years, due to the extensive popularity of medical imaging applications in healthcare settings and the increased interest in telemedicine technologies, it is important to minimize both storage and transmission bandwidth necessities required for archival and communication of related data, preferab...

This paper presents our contributions in the design and implementation of a DICOM compliant environment for structured reporting in echocardiography. A structuring methodology of the medical information aiming to extend the set of contexts and templates with those corresponding to non-numerical findings is the first major contribution. The enhancement of DICOM mechanisms used in the report crea...
