The EPI-CT project aims to collect an international cohort of paediatric patients undergoing CT examinations to estimate cancer risk after exposure to low doses of ionizing radiation. This is done by linkage with national cancer registries and analysis of cancer incidence in respect of individual radiation doses. The dosimetry information is calculated based on the technical parameters of the images acquired during scan.
The PerMoS – Performance and Monitoring Server for Medical Data is used to perform the data collection from PACS. The lightweight, easy to install PerMoS Upload Client is used to query, treat and securely collect the pseudonymous technical DICOM header metadata and transfer it to the central PerMoS Server. Each study participant can securely access the collected data with the PerMoS Data Manager - depending on their role within the study. Special Calculator Components at the server provide different evaluations, like different CT dosimetry calculations.
Based on the aim and design of the European EPI-CT study, the software's specific functionality and design will be demonstrated. First implementations in Germany in the university hospitals Mainz and Mannheim revealed preliminary results on performance and acceptance during data collection as well as challenges in dosimetry and special characteristic of the retrieved data.
The presentation will outline the aims and the design of the EPI-CT study as well as the software design and the software functions. The conclusions include first results, discuss the challenge of dosimetry, the experiences during data collection and characteristics of the collected data.
