Strategic information management plans: the basis for systematic information management in hospitals

• Alfred Winter, Elske Ammenwerth, +14 authors Andreas Winter
• I. J. Medical Informatics
• 2001

Information management in hospitals is a complex task. In order to reduce complexity, we distinguish strategic, tactical, and operational information management. This is essential, because each of… (More)

• Biomedizinische Technik. Biomedical engineering
• 2015

OBJECTIVE The standard ASTM F2119 describes a test method for measuring the size of a susceptibility artifact based on the example of a passive implant. A pixel in an image is considered to be a part… (More)

Software-based automated measurement of susceptibility artifacts on magnetic resonance images

• Andreas Heinrich, Felix Victor Güttler
• 2011

Introduction: MR-compatible implants and instruments for interventions under MR-imaging can cause susceptibility artifacts [1, 2]. Before clinical diagnostics or intervention, it must be known in… (More)

Capacity of IEEE 802.11-Based Ad Hoc Networks with Fairness Constraints

• Andreas Heinrich, Silke Feldmann
• IEEE 17th International Symposium on Personal…
• 2006

The capacity of IEEE 802.11-based ad hoc networks is usually a critical issue because multi-hop communication requires additional capacity which is not available for transmitting application data.… (More)
