International survey on diagnostic reference levels based on clinical indications in plain radiography.

Purpose: To collect and analyze radiation dose-related data as part of international cooperation; to define diagnostic reference levels (DRL) for 24 X-ray projections in plain radiography (DX) considering anatomical region, clinical task, and procedural technique; and to harmonize the exposure practice across country borders.

Methods: A multicenter study was performed in Austria, Germany, Italy, and Switzerland in 2022-23 to provide dose-related data. Healthcare facilities were asked to provide processed data from their dose management systems.

[Radiological dose and metadata management].

This article describes the features of management systems currently available in Germany for extraction, registration and evaluation of metadata from radiological examinations, particularly in the digital imaging and communications in medicine (DICOM) environment. In addition, the probable relevant developments in this area concerning radiation protection legislation, terminology, standardization and information technology are presented.

IVEU: IT-based collection and reporting of radiological examination parameters.

In Germany, each site using ionising radiation in human medicine is assigned to a competent medical authority (CMA) for quality assurance. Duties of these CMAs are, e.g.

[Protection of eye lens in computed tomography--dose evaluation on an anthropomorphic phantom using thermo-luminescent dosimeters and Monte-Carlo simulations].

Purpose: The lens of an eye is a particularly radiosensitive organ. This study investigates two different materials for eye shielding during CT scanning, i. e.
