Life-threatening pacemaker dysfunction associated with therapeutic radiation: a case report.

Reports about pacemaker (PM) dysfunction during irradiation (IR) are very rare, which is because of the extensive protective mechanisms that exist in these devices against electromagnetic interference (EMI). We report a case in which one of the most clinically relevant type of PM malfunctions, a runaway PM, occurred during radiation in a 76-year-old woman who was treated for inoperable esophageal cancer with a course of photon IR. The estimated IR dose of 0.

Integration of ultrasound in a fully digital radiology department.

Objectives: The authors' experiences concerning the use of video-framegrabbers for the integration of ultrasound devices into a fully digital imaging environment are presented.

Methods: Video acquisition workstations (VAW) (Siemens, Gammasonics Inc., Hoffman Estates, IL) are used in our department to link ultrasound devices to the picture archiving and communication system (PACS).

Integration of radiology and hospital information systems (RIS, HIS) with PACS: requirements of the radiologist.

PACS development has now reached a stage where it can clearly be stated that the technology for storage, networking and display in a fully digital environment is available. This is reflected by an already large and rapidly increasing number of PACS installations in USA, Western Europe and Japan. Such installations consist of a great variety of information systems, more or less interconnected, like PACS, HIS, RIS and other departmental systems, differing in both hardware and software.
