Health-enabling technologies for the elderly--an overview of services based on a literature review.

Background: Services for the elderly based on health-enabling technologies promise to contribute significantly to the efficiency and effectiveness of future health care. Due to this promise, over the last years the scientific community has designed a complex variety of these valuable innovations. A systematic overview of the developed services would help to better understand their opportunities and limitations.

Health information systems for home telehealth services--a nomenclature for sensor-enhanced transinstitutional information system architectures.

Home telehealth services for elderly people promise to contribute to a more efficient health care in the future. Though isolated services at a patient's home might make sense for some applications, the full potential of home telehealth only arises through its integration into existing health information systems (HIS) and care processes. We know about traditional HIS architectures.

An approach to simulate and visualize intraoperative scattered radiation exposure to improve radiation protection training.

Intraoperative radiography based on mobile image intensifier systems (C-arms) is widely used during the treatment of trauma and emergency patients. These devices produce scattered radiation, potential hazardous for surgeon and operation room personal (ORP). The propagation and intensity of scattered radiation is not intuitive, is not perceivable by human senses and depends on many variables.

Improving education on C-arm operation and radiation protection with a computer-based training and simulation system.

Purpose: To discuss an approach to improve education in C-arm operation and reduction of radiation hazards based on a computer based training and simulation system called virtX.

Methods: virtX is equipped with a visualization of scattered radiation and means to include patient positioning changes in radiograph simulation. virtX was integrated in a course for ORP and evaluated based on questionnaires.

An approach to calculate and visualize intraoperative scattered radiation exposure.

During the intraoperative radiograph generation process with mobile image intensifier systems (C-arm) most of the radiation exposure for patient, surgeon and operation room personal is caused by scattered radiation. The intensity and propagation of scattered radiation depend on different parameters, e.g.
