    Description / Table of Contents: Zusammenfassung. Die mögliche qualitative Verbesserung des Operationsergebnisses sowie der Zwang, weitere Rationalisierungspotentiale zu realisieren, sind Gründe für die Entwicklung und Anwendung von Robotersystemen in der laparoskopischen Chirurgie. Ahmen die Robotersysteme weitgehend die Funktionen des menschlichen Kameraassistenten nach, basiert das Image Tracking System (ImagTrac, Olympus, Tokio) auf einem anderen Prinzip: Eine Zoomfunktion erlaubt bei starrer Kamera- und Teleskopmontage den durch „voice-control“ aktivierten Wechsel zwischen Übersicht und Nahsicht. Bei Nahsicht können 4 verschiedene Bildausschnitte angesteuert werden. Die Ergebnisse einer klinischen Anwendungsstudie mit Kontrollgruppe zeigen, daß das System 1. den Verzicht auf den menschlichen Kamerahalter ohne Sicherheitsverlust für den Patienten bei zum Teil größerem Komfort für den Operateur ermöglicht und 2. erlaubt, visceralchirurgische, laparoskopische Routineoperationen, wie laparoskopische Cholecystektomie und laparoskopische Hernienreparation, als „Operateur-Schwester-Operation“ (Solochirurgie) auszuführen sowie 3. im Vergleich zu Robotersystemen, die ein ähnliches Leistungsspektrum aufweisen, kostengünstiger einzusetzen ist.
    Notes: Abstract. The potential for improvement of the results of laparoscopic operations as well as necessity of enhanced efficiency in the health-care systems are the main reasons for development and practical use of robotic systems in the field of laparoscopic surgery. While robotic systems imitate the human camera-holder the Image Tracking System (ImagTrac, Olympus,Tokio) is based on another principle: A voice-activated zoom function allows change between overview and detailed view. In the zoom-in position it is possible to select four different fields of view. The results of a clinical trial with control group show that the system: 1. Makes it possible to dispense with the human camera-holder without compromising patient safety, sometimes at greater convenience to the surgeon. 2. Makes it possible for routine laparoscopic operations such as laparoscopic cholecystectomy and laparoscopic hernia repair to be performed (as solo surgery) by a team of a surgeon and a nurse only. 3. Is more cost-effective than robotic systems with a similar range of features.

    Notes: Abstract We present magentic resonance and magnetization measurements in the low dimensional spin system CsNiCl3 for temperatures down to 1.5 K and in magnetic fields up to 14 T. The frequency range from 35 GHz to 380 GHz is much larger than for previous experiments. The outstanding features of these experiments are a spreading of the magnetic resonance branches in high fields belowT N and an upturn of the magnetization at higher fields and for temperatures below 20 K. Wheras we can interpret our resonance data with a six sublattice model invoking a large interchain exchange, the magnetization points to typical one dimensional behaviour in higher fields. A theory for a consistent description of resonance data, spinwave spectra and magnetization is required.
