The “radiotherapy structure set” (RTSTRUCT) object of the DICOM standard is used for the transfer of patient structures and related data, between the devices found within and outside the radiotherapy department. It contains mainly the information for regions of interest (ROIs) and points of interest (e.g., dose reference points). In many cases, rather than manually drawing these ROIs on the CT ...

Image processing is one of the most researched area these due to the flooding of the internet with an overload of images. The noble medicine industry is not left untouched. It has also suffered with an excess of patient record storage and maintenance. With the advent of automation of the industries in the world the medicine industry has sought to change and provide a more portable feel to it. L...

Wesentliche Defizite verfügbarer Software zur Planung von Stenting-Interventionen sind die Beschränkung auf zweidimensionale Projektionen der Gefäße und Stents sowie fehlendes Wissen über das Verhalten des Stents im Gefäß. Zur Ermittlung der Stentabmessungen werden derzeit in 2D-CT Schichten am betreffenden Areal Gefäßdurchmesser und Länge gemessen. Die Praxis zeigt, dass bei stark gekrümmten G...

The goal of this work is to build an ontology of Magnetic Resonance Imaging. The MRI domain has been analysed regarding MRI simulators and the DICOM standard. Tow MRI simulators have been analysed: JEMRIS, which is developed in XML and C++, has a hierarchical organisation and SIMRI, which is developed in C, has a good representation of MRI physical processes. To build the ontology we have used ...

Zusammenfassung. In der Arbeit wird ein Netzwerkalgorithmus für die Kompression und die Rekonstruktion von DICOM-Bildern präsentiert. Der Algorithmus besteht aus zwei Teil: die Bitebenen des Originalbildes werden aufgrund einer vorläufigen Segmentation und Analyse des Bildinhaltes klassifiziert; auf Basis der Klassifikationsergebnisse wird das DICOM-Bild in zwei Bilder aufgeteilt. Danach werden...

Picture archiving and communication systems (PACS) require highspeed networks to transmit large image files between components. While transmitting data through public networks, privacy, authenticity, and integrity have always been some critical problems. Recent years, IPv6 brings significant improvements in mechanisms for assuring a higher level of security. In this paper, we first analyzes how...
