[The new possibilities of digital luminescence radiography (DLR) and digital imaging data processing for the making of field verification images].

Background: Treatment verification for reasons of quality control takes an important place in daily radiotherapeutic work. The quality of conventional, e.g.

[A simple method of digitizing analog scintigrams for quantification and digital archiving].

This study was undertaken to evaluate a quick, reliable and cheap method of digitizing analog scintigrams. 40 whole-body bone scintigrams were obtained simultaneously in analog and genuine digital format. The analog scans on x-ray film were then digitized secondarily by three different methods: 300 dpi flat-bed scanning, high-resolution camera scanning and camcorder recording.

[Digital archiving and communication in hospitals].

Different concepts and already available components of a HIS (Hospital Information System) for archiving all data in a hospital are described. Using the example of the Kiel University Hospital, it is shown that a complete HIS-system can be made from already commercially available components.

[Do strong static magnetic fields in NMR tomography modify tissue perfusion?].

Findings obtained in humans and test animals raised the question whether strong static magnetic fields as used in NMR-tomography may affect tissue perfusion. In two test series including 20 subjects, each skin blood flow at the thumb was determined by heat clearance, and forearm blood flow was measured by venous occlusion plethysmography. For comparative purposes, measurements were carried out bilaterally at both extremities.
