Produktentwicklung mit Augenmaß im Hinblick auf die ökonomischen Verhältnisse im Gesundheitswesen

Zusammenfassung

Die Produktentwicklung in der Medizintechnik vollzieht sich gleichermaßen in den Bereichen der Hard- und der Software. Eine kostengünstige Möglichkeit, die Leistungsfähigkeit vorhandener Medizinprodukte zu steigern, besteht in der Entwicklung angepasster Software, die darüber hinaus auch einfacher nachzurüsten ist. So können beispielsweise die Sensitivität und die räumliche Auflösung eines PET-Scanners oder einer SPECT-Gammakamera durch den Einsatz aufwendiger Rekonstruktionsverfahren erheblich verbessert werden. Die Nutzung dieser rechenintensiven Verfahren in der Routine wird durch die rasante Entwicklung im Bereich der Computertechnologie ermöglicht. Anhand dreier Beiträge wird gezeigt, welchen Nutzen reine Software in der täglichen Routine zu bringen vermag.

Abstract

Product development in medical technology is taking place likewise for hardware and software. A cost-effective way to improve the performance of existing medical products is the development of dedicated easy upgradable software. Installing additional complex reconstruction algorithm packages can improve the sensitivity and spatial resolution of PET scanners or SPECT systems dramatically. The rapid improving computer power today allows the implementation of computational very intensive algorithms. For three applications the advantage of pure software implementations in the daily routine is shown.
